Description

Technical field

[0001] The present invention relates to an intelligent track laying method and intelligent track laying equipment, which belong to the technical field of rail transit railway track laying.

Technical background

[0002] With the rapid development of rail transit, both manual track laying and semi-mechanized track laying can no longer meet the requirements of railway construction in terms of progress and quality. Intelligent and automated track laying have become the development trend of railway construction.

[0003] In the entire process of automated track laying, how to automatically place and recycle the rollers, how to quickly grasp and lock the rails, implement traction and push on the rails, and how to quickly place and fasten the rail fasteners are issues that the industry continues to study. So far, there still exist defects that the operation speed is slow, some operations still require manual participation and manual remediation, and so on.

[0004] The defects are mainly manifested as follows:

I. As for the roller placement and rail traction operating vehicle and the rail gripping manipulator of the rail sorting vehicle, their main problems are that the rail is not easy to lock after being gripped, the rail is easy to slip when it is pushed, it is necessary to manually drive a wedge block to lock the rail, and it takes time to withdraw the driven wedge block when the rail is released.

II. As for the roller gripping device of the roller recycling vehicle, its main problems are that the recycling mechanism is not set up properly, and the rollers recycled on the operating vehicle need to be manually pushed outside the track bed from under the rail to the middle of the track bed in advance, and the rollers should be placed according to the specified positions and postures, which will take a lot of time and labor costs.

III. As for the roller placement and rail traction operating vehicle and the roller gripping manipulator of the roller recycling vehicle, their main problems are that when improper operation causes the grabbing tool to forcefully collide with objects or be impacted by overload, some of executive components of the manipulator are easily damaged, and the downtime for maintenance requires a lot of time wasted.

IV. As for the roller placement and the roller gripping device of and rail traction operating vehicle, its main problem is that there is only one set of roller placement device, which results in the slow speed of placing the rollers.

5. The fastener fastening operating vehicle is limited to the mechanical device to tighten the track spikes, and in the rail fixing process, the insertion of the insulating block and the placement of the spring bar still need to be completed manually, which also extends the working time and increases the labor costs.

[0005] Through a domestic search, it is found that Chinese Utility Patent Application No. 201811510758.4 for utility model entitled "ROLLER RECYCLING AND PLACING DEVICE FOR TRACK LAYING, RAIL TRACTOR AND RAIL LAYING OPERATION METHOD" is the closest to the present invention. However, the solution described in the patent has the following defects:

1. There is only one set of automatic roller placement device. Due to the long run distance from grabbing the rollers to placing the rollers, the number of rollers placed per unit time is small, resulting in slow operation speed and low efficiency throughout the track laying process.

2. When grasping and locking the rail, the solution involves a process of manually driving the wedge block to lock the rail, which not only delays the time to lock the rail, but also takes time to withdraw the wedge block when the rail is released.

3. The roller placement device runs on longitudinal rails, lateral rails, and vertical rails. Its rail running mode adopts a screw-nut relative rotation propulsion mode. It requires a high-speed rotation of either the screw or the nut to move quickly on the track, resulting in fast abrasion of the screw and nut and high energy consumption.

[0006] Through a domestic search, it is also found that Chinese Application No. 201420327443.7, entitled "RAIL GRABBING DEVICE", is similar to the present invention. Its main technical features are as follows: this patent relates to a rail grabbing device, comprising a grappling hook, a chain link, and an adjustment mechanism, wherein the grappling hook, chain link, and conciliation machine are hinged through pin shafts, and the grappling hook is used to tightly grab the rail. The grappling hook comprises hook claws, a positioning pin, a sliding lock iron, and a connecting plate, wherein the connecting plate is hinged to two hook claws through pin shafts, the sliding lock iron slides in a sliding groove on the connecting plate, and the hook claws are limited by the sliding lock iron. The adjustment mechanism comprises a hanging rod, a nut adjusting handle, a fixed seat, and an adjusting nut, wherein the hanging rod is slidably connected to the fixed seat, an end of the hanging rod is provided with threads that match the adjusting nut, and the adjusting nut is rotated to drive the hanging rod to move up and down.

[0007] This patented solution is only used to grasp the rail and lift it upwards. The entire structure is a flexible structure, which cannot instantly transmit lateral force, longitudinal force, and downward vertical force to the rail, and cannot use the device to quickly grasp and lock the rail. It is difficult to instantly transmit longitudinal force to the rail to realize the longitudinal push of the rail, and the rail cannot be loosened quickly after the rail is grasped and locked.

[0008] Through a domestic search, other track laying patents are also found. Since these patents have different objectives and problems, no track laying equipment can meet requirements of an intelligent, automated, high-standard, and high-speed track laying system.

[0032] Rails 81: a rail head 82 located at an upper part of the rail, a rail bottom 85 located at a bottom part of the rail, and lower bottom surfaces on both sides of the rail head 82, which are a first bottom surface 83 and a second bottom surface 84, respectively.

[0033] Pre-installed sleepers 89: they have been installed on both sides of the track bed before the track is laid, and all accessories are pre-installed in place, and will be finally fixed.

[0034] Iron base plates 90: there are upward limiting bosses 91 at both ends of the Iron base plate, they have been installed on the pre-installed sleepers 89 before the track is laid, and an under-rail backing plate 92 is placed between the limiting bosses 91 at both ends.

[0035] Insulating blocks 93: an L-shape is formed by an inserting block 94 and a pressing block 95, and the inserting block 94 and the pressing block 95 are integrally molded.

[0036] Spring bars 96: the spring bar has a front-end lower jaw 97. Before the track is laid, the front-end lower jaw 97 has been temporarily pressed on the limiting boss 91 of the Iron base plate 90.

[0037] Track spikes 98: the rack spike has a handle, and the track spike passes through the spring bar 96 during application, and its handle is pressed on the spring bar 96.

[0038] The present invention relies on various operating vehicles to realize the intelligent track laying process, which mainly comprises: laying rails 81 on the pre-installed sleepers 89 on both sides of the track bed, so that the bottom surface of the rail bottom 85 of the rail 81 is pressed against the under-rail backing plate 92 between limiting bosses 91 at both ends of the Iron base plate 90; and fixing the rails 81 with spring bars 96, track spikes 98 and so on.

[0039] The method of the present invention will be described in detail below:
As shown in FIGS. 1, 10, 20, 21, 22, 23 and 24, an intelligent track laying method comprises: arranging a complete set of track laying equipment composed of multiple operating vehicles that is controlled by an intelligent control system; using a rail sorting vehicle 3 in the equipment to automatically grab front ends of two rails 81 from a rail conveyor vehicle 2 in the equipment on the left and right and directionally push the two rails 81 to a rail pushing vehicle in the equipment; automatically pushing the two rails 81 by the rail pushing vehicle toward a roller recycling vehicle 5 in the equipment; automatically delivering the two rails 81 toward a rail tractor 6 in the equipment by the roller recycling vehicle 5; automatically grabbing the front ends of the two rails 81 by the rail tractor 6 and making the rail tractor 6 move forward; at the same time, a roller gripping device 24 provided on the rail tractor 6 continuously placing rollers 7 forward along with the vehicle at set positions on both sides of a track bed; making two rails 81 behind be continuously placed on the rollers 7 on both sides of the track bed and continuously dragged forward along with the vehicle on the rollers; then, by using a roller recycling vehicle behind, automatically recycling the rollers 7 pressed under the rails 81 to the roller recycling vehicle 5 to put the rails between the two limiting bosses 91 of the Iron base plate 90 of the pre-installed sleeper 89; manually performing interval-type preliminary fixing of the rails 81 that fall on sleepers; and finally automatically completing a fastening operation of the rails 81 by a fastener fastening vehicle 1, thereby realizing intelligent track laying.

[0040] The interval-type preliminary fixing is a way of taking one pre-installed sleeper for every interval of N (in general, 2-6) pre-installed sleepers, wherein the operation of placing insulating blocks and fastening fasteners is completed by manually placing the rails with this pre-installed sleeper, and the preliminary fixing of the rails 81 on both sides is realized.

[0041] The length of the rail 81 described in the above method is generally 500 meters at present, and all the operating vehicles in front of the rail conveyor vehicle 2 take the placement of one rail on each side of the track bed as a work process. The fastener fastening vehicle 1 behind the rail conveyor vehicle 2 can be regarded as always following the rail conveyor vehicle 2 to perform the fastening operation forward until the rails on the rail conveyor vehicle 2 are laid.

[0042] In this way, in the entire operation process of the entire track laying equipment, except for the need for drivers to drive part of the operating vehicles, process monitoring personnel to monitor the working conditions of each operating vehicle, and workers to perform preliminary fixing of the rails that fall on sleepers, other operations no longer require manual participation, so that the operation efficiency of the entire equipment is significantly improved, and the quality standard of the operation completed under the control of the automatic control system can be fully ensured.

[0043] As shown in FIGS. 1, 2, 3, 4, 10, 11, 20, 21, 22, 24 and 25, the delivering the two rails 81 toward the rail tractor 6 by the roller recycling vehicle 5 is arranging guide rail devices 9 on both sides of the roller recycling vehicle 5, making the two rails 81 pass through the guide rail devices 9 arranged on both sides, respectively, and pushing the two rails 81 toward the rail tractor 6 in the equipment by the rail pushing vehicle.

[0053] The equipment of the present invention will be described in detail below:
In order to simplify the description and facilitate the understanding, the structures and functions of devices or components with common features that appear more frequently below will first be described:
Roller gripping device 24: as shown in FIGS. 4 and 5, it has a longitudinal rail 13, a lateral rail 14 running on the longitudinal rail 13, and a vertical rail 15 running on the lateral rail 14; its running mode adopts a running mode of gears and racks in cooperation, and the racks comprise a longitudinal rack, a lateral rack and a vertical rack, which are arranged on the longitudinal rail 13, the lateral rail 14 and the vertical rail 15, respectively.

[0054] The roller gripping device 24 further has a longitudinal drive seat 16 fixed on one side of the lateral rail 14. The longitudinal drive seat 16 is provided with a longitudinal drive gear driven by a motor. The gear teeth of the longitudinal drive gear mesh with the teeth of the longitudinal rack, and the rotation of the longitudinal drive gear can drive the lateral rail 14 to move longitudinally.

[0055] The roller gripping device 24 further has a longitudinal double drive seat 17 running on the lateral rail 14, and the vertical rail 15 runs on the longitudinal double drive seat 17.

[0056] The longitudinal double drive seat 17 is provided with a lateral drive gear driven by a motor, the gear teeth of the lateral drive gear mesh with the teeth of the lateral rack, and the rotation of the lateral drive gear drives the longitudinal double drive seat 17 and the vertical rail 15 to move laterally.

[0057] The longitudinal double drive seat 17 is provided with a vertical drive gear driven by a motor, the teeth of the vertical drive gear mesh with the teeth of the vertical rack, and the rotation of the vertical drive gear drives the vertical rail 15 to move vertically.

[0058] The roller gripping device 24 has a roller manipulator 18 installed at a lower end of the vertical rail 15.

[0059] Roller manipulator 18: as shown in FIG. 5, it has two clamping arms 19 symmetrically arranged on the left and right and respective clamping palms 20 under the two clamping arms 19. Above the two clamping arms 19 is an actuator with a pushing cylinder to open and close the two clamping arms 19, and the two clamping palms 20 are used to clamp or release the roller 7 with the opening and closing of the two clamping arms 19. In the present invention, the roller manipulator 18 is designed to prevent damage to important parts in the event of a collision or overload, that is: an upper gripping arm 19 is disconnected from a lower gripping palm 20, a self-damaging block 21 is provided between the gripping arm 19 and the gripping palm 20, and the clamping arm 19 and the clamping palm 20 are fixedly connected by the self-damaging block 21; and the self-damaging block 21 is provided with a broken groove 22 that is easy to break off.

[0060] The roller manipulator 18 is arranged in the roller gripping device 24 of the rail tractor 6 and the roller gripping device 24 of the roller recycling vehicle 5, and is used to grasp the roller wheel 8 of the roller.

[0061] Rail two-way locking manipulator: as shown in FIGS. 6, 7, 8 and 9, the rail two-way locking manipulator 23 comprises a mounting body 25 fixed on the sorting device or rail traction device, a rotating frame 26 installed on the mounting body 25 through a rotating shaft, a tilt propeller 251 with one end acting on the rotating frame 26 to push the rotating frame 26 to rotate, and a clamping assembly installed on the rotating frame 26. The clamping assembly comprises a clamping frame 27 installed in the rotating frame 26, and the clamping frame 27 has a first splint 28 and a second splint 29. The first splint 28 and the second splint 29 are provided with a first hanging pin hole and a second hanging pin hole, respectively. The first hanging pin hole and the second hanging pin hole have a first hanging pin 30 and a second hanging pin 31, respectively. When the rail 81 is grasped, lower ends of the first splint 28 and the second splint 29 can be inserted under the first bottom surface 83 and the second bottom surface 84 on both sides of the rail head 82, respectively. Bottom ends of first splint 28 and second splint 29 of the clamping frame 27 are divided into a first front foot 32 and a first rear foot 33, and second front foot 34 and a second rear foot 35, respectively. When the first pin 30 and the second pin 31 hang on the first bottom surface 83 and the second bottom surface 84 of the rail head, respectively, there is a gap between each of the first front foot 32 and the first rear foot 33 and a first top surface 86 of the rail bottom 85, and there is a gap between each of the second front foot 34 and the second rear foot 35 and a second top surface 87 of the rail bottom 85.

[0062] When a lower end of the clamping frame 27 tilts forward with the rotating frame 26, the first hanging pin 30 and the first rear foot 33 support the first bottom surface 83 and the first top surface 86, respectively, the second hanging pin 31 and the second rear foot 35 support the second bottom surface 84 and the second top surface 87, respectively, and the clamping assembly locks the rail 81.

[0063] When the lower end of the clamping frame 27 tilts backward with the rotating frame 26, the first hanging pin 30 and the first front foot 32 support the first bottom surface 83 and the first top surface 86, respectively, the second hanging pin 31 and the second front foot 34 support the second bottom surface 84 and the second top surface 87, respectively, and the clamping assembly also locks the rail 81.

[0064] When the clamping frame 27 returns to a vertical position with the rotating frame 26, locking of the rail 81 by the clamping assembly is released.

[0065] Another important feature of the rail two-way locking manipulator 23 is that after the rotating frame 26 is tilted to lock the rail, as long as the rail 81 is not absolutely horizontal, that is, the rail 81 forms an angle with a horizontal plane, when the rail two-way locking manipulator 23 exerts a horizontal force on the rail in a horizontal direction, a component force perpendicular to the rail will be generated, so that the rail two-way locking manipulator 23 will lock the rail tighter, which is very helpful for horizontal pushing and pulling of the rail 81.

[0066] Propulsion cylinder: the present invention uses Propulsion cylinders in many mechanisms, especially in the rail two-way locking manipulator. These Propulsion cylinders may be oil cylinders, pneumatic cylinders, or electric cylinders.

[0067] As shown in FIGS. 1, 22, 23 and 24, intelligent track laying equipment comprises a rail conveyor vehicle 2, and a rail sorting vehicle 3 with a rail sorting device, a rail pushing vehicle with a rail pushing device, and a rail tractor 6 with a rail traction device 6 that are sequentially located before the rail conveyor vehicle 2, wherein a roller gripping device 24 is still provided on the rail tractor 6, and a special roller recycling vehicle 5 is provided between the rail pushing vehicle and the rail tractor 6, which has a roller gripping device 24 and a roller drag-out device; and a fastener fastening vehicle 1 is provided behind the rail conveyor vehicle 2, and the fastener fastening vehicle 1 has a fastening device for installing fasteners to fix a rail 81.

[0072] II. Roller recycling vehicle 5. As shown in FIGS. 1, 3, 4, 5, 10, 11, 12, 22 and 23, the roller recycling vehicle 5 is walked on the track bed 99 through crawler wheels and rubber wheels during operation.

[0073] Guide rail devices 9 that cooperate with the roller drag-out device and the roller gripping device 24 are provided below both sides of the underframe of the roller recycling vehicle 5. A left raising opening 41 and a right raising opening 42 are provided in the middle and rear of the underframe of the roller recycling vehicle 5. A roller recycling area 11 is provided on the underframe in front of the left raising opening 41 and the right raising opening 42. The roller recycling area 11 is provided with a roller basket 12.

The temporary fixator 52 has a temporary clamping component. During operation, the roller recycling vehicle 5 is continuously driven forward. The temporary clamping component clamps the rail 81 under the underframe of the roller recycling vehicle 5, and forces the retrograde frame 49 to remain stationary relative to the track bed 99 and slide in an opposite direction relative to the roller recycling vehicle 5 on the two-way rail 51. The one-way propulsion mechanism comprises a propulsion tube and an electric cylinder propulsion rod 54 53 longitudinally fixed in the middle of the retrograde frame 49. The propulsion tube 53 is fixed to the retrograde frame 49 with the lower surface of the rear section. The electric cylinder propulsion rod 54 is located in the propulsion tube 53, and can extend out from a rear end of the propulsion tube 53. A propulsion head 55 at a rear end of the electric cylinder propulsion rod 54 can withstand the frame body of the rear part of the general assembly frame 48 and apply a backward thrust to the general assembly frame 48, so that the retrograde frame 49 obtains a forward reaction force enabling the entire retrograde roller drag-out device 47 to quickly slide forward after completing one lateral drag-out of the roller 7, so as to perform the next task of dragging out the roller 7 laterally.

[0075] The electric cylinder propulsion rod 54 further has a rail-type reinforcing rod 541 extending along with the electric cylinder propulsion rod 54 when the electric cylinder propulsion rod 54 is extended, which shares the gravity with the extended section of the electric cylinder propulsion rod 54. At least two sliders 542 for the rail-type reinforcing rod 541 to slide are provided below the rail-type reinforcing rod 541. The slider 542 is fixedly arranged on a horizontally arranged support plate 544 fixedly connected to the retrograde frame 49 above the propulsion tube 53. A rear end of the rail-type reinforcing rod 541 is connected to the propulsion head 55 at the rear of the electric cylinder propulsion rod 54 through a connecting plate 543. Restricted by the at least two sliders 542 for the rail-type reinforcing rod 541 to slide, the rail-type reinforcing rod 541 maintains a horizontal posture.

[0076] The above-mentioned front and rear directions are based on the forward driving direction of the roller recycling vehicle 5 as a forward direction.

[0077] The retrograde roller drag-out device 47 uses the lateral hook component 50 to laterally drag the rollers 7 from under the rails 81 on both sides to the middle of the track bed 99 and regularly place them on both sides of the track bed 99.
