Description

TECHNICAL FIELD



[0001] The disclosure relates to the technical field of container multimodal transportation, and in particular to a container rail-road transfer system.

BACKGROUND OF THE INVENTION



[0002] At present, the development level of multimodal transportation in China is still relatively low, and road transportation has been the mainstay for a long time. The more prominent problems on multimodal transportation include: the poor coordination among roads, railways and waterway transport; the imperfect market environment; the inadequate laws, regulations and standards; and the lag in the application of advanced technologies; and so on. The scale of multimodal transportation volume only accounts for 2.9% of the total social freight volume, which is far below the development level of the United States. The operating efficiency of multimodal transportation is not high, and the cost for cargo transshipment accounts for about 30% of the total logistics cost, resulting in the domestic logistics cost much higher than the logistics cost of those countries with a developed logistics industry such as the United States, Canada and Europe. Strengthening the research and development of the core technology and equipment of the logistics industry, and promoting the industrialization of key technologies and equipment, have become the main development tasks of the national logistics industry in the medium and long term. As of September 1, 2016, there are more than 1,506 container handling stations in 18 railway bureaus across China, and there are huge application prospects for rail-road transit and transfer equipment.

[0003] A container handling line of an electrified railway station generally uses rail-road transit and transfer equipment which is not connected in a network, that is, an electrified railway contact network is disconnected in a container handling area, and rail-mounted gantry cranes, container reach stacker or other lifting equipment are used in the container handling area for loading, unloading and transshipment of containers between railway and road.

[0004] The rail-mounted gantry cranes in the prior art is bulky and costly, and requires a large work site, thereby reducing the available space in a work site. In a transit process, a train arrived at/departing from a station cannot directly enter a handling area, thus shunting and connecting operations are required, which results in a low efficiency in rail-road transshipment.

The two-way side pick-up device enables the container to move horizontally between the railway container flat car and the container lorry, which makes the container transshipment process stable and safe, and avoids the interference between the container rail-road transfer system and the electrified railway contact network during the transshipment process. Due to the adoption of the two-way side pick-up device, the container rail-road transfer system of the present disclosure is simplified and occupies a smaller space, thereby simplifying the transfer procedures and improving the transfer efficiency.

By adopting the container handling device which is used to lift the container on the container lorry and place the container on the two-way side pick-up device, and/or lift a container on the two-way side pick-up device and place the container on the container lorry, the container at the position of the container lorry can be lifted and/or placed conveniently and quickly, thereby improving lifting efficiency during the transshipment process. In addition, by adopting the container handling device, the structure of the container rail-road transfer system of the present disclosure is simplified, and the cost thereof is reduced. In this way, the container rail-road transfer system provided by the present disclosure can effectively solve the technical problems in the prior art that the utilization rate of working site on a container handling line of the electrified railway station is lower and the rail-road transfer efficiency is lower, and realize the following effects: there is no interference on the electrified railway contact network; the rail-road transfer procedures are simplified; the operating cost of the container rail-road transfer system is reduced; and the utilization rate of working site and the rail-road transfer efficiency are both improved.

Twelve sets of second limit wheels 4023 can ensure that an upper tray mechanism 401 moves along a fixed straight line. The arrangement of positions of the six sets of second limit wheels 4023 must satisfy that at least two sets of second limit wheels 4023 play the role of fixing and limiting inside the tray mechanism 401 under any working conditions.

Example 7

The travel wheel 4015 is rollingly disposed on the raising-and-lowering platform 4031 of the raising-and-lowering mechanism 403. When the bridging mechanism 402 extends from the initial position, one end of the second concave groove member 4013 rests on the second slideway 4022, and another end thereof is supported on the raising-and-lowering platform 4031 by the travel wheel 4015.

[0055] The third driving component 4011 is configured to drive the second concave groove member 4013 to extend from an initial position to the railway container flat car 7, or retract from the railway container flat car 7 to the initial position. The fourth driving component is configured to drive the second concave groove member 4013 to extend from the initial position to the parking position of the container lorry, or retract from the parking position of the container lorry to the initial position.

[0059] The third cylinder hole and the fourth cylinder hole are respectively provided at diagonal ends of two second concave groove members 4013. When the tray mechanism 401 slides toward the railway container flat car 7, the third connection cylinder acts and the rod body thereof extends into the third cylinder hole, and the third actuator cylinder pushes the tray mechanism 401 to extend. During this process, the fourth connection cylinder and the fourth actuator cylinder do not work. When the tray mechanism 401 slides towards the container lorry, the fourth connection cylinder acts and the rod body thereof extends into the fourth cylinder hole, and the fourth actuator cylinder pushes the tray mechanism 401 to extend. During this process, the third connection cylinder and the third actuator cylinder do not work.

Example 13



[0060] A rack and pinion mechanism may also be used to provide a transfer thrust for the third driving component 4011 and the fourth driving component.

[0061] Referring to Figs. 12 and 13, the two-way side pick-up device 4 according to one or more embodiments of the present disclosure further comprises an anti-tipping assembly. The anti-tipping assembly comprises a horizontal plate 405 disposed on a side of the second concave groove member 4013, and a limit frame 404 disposed on the raising-and-lowering platform 4031. The bottom of the limit frame 404 is fixed on the raising-and-lowering platform 4031, and the top thereof is a top plate arranged in parallel with the horizontal plate 405. The horizontal plate 405 is fitted under the top plate with a clearance.

[0062] When the tray mechanism 401 is in an extended state relative to the bridging mechanism 402, the anti-tipping assembly can prevent the tray mechanism 401 from tipping under its own weight.

[0063] The following describes the lifting device 2 according to one or more embodiments of the present disclosure.

Example 15



[0064] Referring to Figs. 8-10, the lifting device 2 comprises a first track 205 disposed on the carrying platform 3, a second track 206 slidably disposed on the first track 205, door-shaped support mechanisms symmetrically disposed at two ends of the carrying platform 3, two container twist lock parts 204 disposed under the top of the door-shaped support mechanisms at two sides, a first slide driving mechanism, and a second slide driving mechanism.

[0065] The first track 205 is arranged along the length direction of the carrying platform 3 and is parallel to the railway track. The second track 206 is arranged perpendicular to the first track 205. Four container twist lock parts 204 are configured to cooperate with corner fittings at four corners on top of the container 6 to lock or unlock the container 6.

[0066] The door-shaped support mechanism comprises a first telescopic leg 201, a second telescopic leg 202, and a crossbeam 203. The container twist lock parts 204 are fixed under the crossbeam 203 at two sides. A fixed end of the first telescopic leg 201 is slidably disposed on the second track 206, and a movable end is fixedly connected to one end of the crossbeam 203. A fixed end of the second telescopic leg 202 is fixedly connected to another end of the crossbeam 203, and a movable end is in a suspended state. The first slide driving mechanism is configured to drive the second track 206 to slide along the first track 205. The second slide driving mechanism is configured to drive the door-shaped support mechanisms to slide along the second track 206.

[0067] Before raising and lowering the container 6 on the railway container flat car 7, by sliding the door-shaped support mechanisms along the second track 206, the second telescopic leg 202 is extended to the side of the railway track. Thereafter, the door-shaped support mechanisms can be slide along the first track 205 so that the four container twist lock parts 204 on the door-shaped support mechanisms correspond to the positions of the corner fittings on the top of the container 6, and then the second telescopic legs 202 are extended to make themselves fixed on the ground on the side of the railway track.

[0068] A first member 207 is fixed on the bottom of the second track 206. The first member 207 is provided with a chute on the bottom thereof, and the chute is adapted to the first track 205. A first actuator cylinder is disposed inside the first telescopic leg 201 to drive the first telescopic leg 201 to extend or retract. A second actuator cylinder is disposed inside the second telescopic leg 202 to drive the second telescopic leg 202 to extend or retract.

[0069] The following describes two specific structures of the first slide driving mechanism and the second slide driving mechanism.

Example 16



[0070] The first slide driving mechanism and the second slide driving mechanism are hydraulic cylinders. A fixed end of the first slide driving mechanism is fixed on the carrying platform 3, and an output end thereof is fixedly connected to the first member 207. A fixed end of the second slide driving mechanism is fixed on the first member 207, and an output end thereof is fixedly connected to the first telescopic leg 201.

Example 17



[0071] The first slide driving mechanism is a motored screw. A fixed end of the motored screw is fixed on the carrying platform 3, and an output end thereof is fixedly connected to the first member 207. The second slide driving mechanism is a geared motor 208. A side of the first member 207 is provided as a rack that cooperates with a gear of the geared motor 208. The geared motor 208 is fixed on the first telescopic leg 201. When the geared motor 208 works, the gear rotates relative to the side of the first member 207, and thus drives the first telescopic leg 201 to slide along the second track 206.

[0072] The following introduces the container handling device according to one or more embodiments of the present disclosure.

Example 18



[0073] Referring to Fig. 11, the container handling device 1 comprises a first top beam 103, a second top beam 104, a third top beam 105, four telescopic columns 101 connected under the first top beam 103 and the second top beam 104, a spreader 106 fixed under the third top beam 105, and a support beam 102. Two telescopic columns 101 under the first top beam 103 are fixed on the carrying platform 3, and a distance between the telescopic columns 101 is greater than a length of the container 6.

[0074] Two telescopic columns 101 under the second top beam 104 are disposed on the ground, and the second top beam 104 is parallel to the first top beam 103. The parking position of the container lorry is between the first top beam 103 and the second top beam 104. The third top beam 105 is fixed between the first top beam 103 and the second top beam 104. The spreader 106 is configured to cooperate with corner fittings at four corners on the top of the container 6 to lock or unlock the container 6. A third actuator cylinder is disposed inside the telescopic column 101 to drive the telescopic column 101 to extend or retract. The support beam 102 is fixed between the telescopic columns 101 under the second top beam 104. After the bridging mechanism 402 is extended, an end of the first concave groove member 4021 is pressed against the support beam 102. The support beam 102 is parallel to the second top beam 104. The support beam 102 makes the structure of the whole device more stable. At the same time, the support beam 102 can provide support for a lateral movement equipment such as the two-way side pick-up device 4 to ensure that the container 6 is stable and safe during the transfer process. Specifically, a side end of the two-way side pick-up device 4 will fall on the support beam 102 when it moves to the side of the container lorry, so that the container 6 can fall between two support points at the bottom of the two-way side pick-up device 4 to ensure a stable support.

[0075] The operating principle of the container handling device 1 is as below: when the container 6 on the container lorry is transferred to the railway vehicle, the container lorry travels to the parking position, and the telescopic columns 101 descend synchronously, so that the spreader 106 is lowered and locked with the corner fittings on the top of the container 6; then the telescopic columns 101 rise synchronously to lift the container 6; and then the container lorry drives away from the parking position, so that the lateral movement equipment such as the two-way side pick-up device 4 can transfer the container 6 to the railway vehicle on a side thereof. When the container 6 on the railway vehicle is transferred to the container lorry, the lateral movement equipment such as the two-way side pick-up device 4 transfers the container 6 on the railway vehicle to the parking position of the container lorry, and the telescopic columns 101 of the container handling device 1 descend synchronously so that the spreader 106 is lowered and locked with the corner fittings on the top of the container 6; thereafter, the telescopic columns 101 rise synchronously to lift the container 106, and the lateral movement equipment such as the two-way side pick-up device 4 moves away from the parking position of the container lorry; afterwards, the container lorry enters the parking position, and the telescopic columns 101 descend synchronously to place the container 6 on the container lorry; then the spreader 106 and the corner fittings on the top of the container 6 are unlocked, and the transfer process is completed. In this way, the container handling device 1 can conveniently and quickly realize the lifting or lowering of the container at the position of the collecting lorry, which improves lifting efficiency during the transfer process. Additionally, by adopting the container handling device 1, the container rail-road transfer system is simplified and the cost thereof is reduced.

Example 19



[0076] Referring to Fig. 1, the container rail-road transfer system further comprises a mobile platform 5. The mobile platform 5 comprises a first steel rail, a second steel rail, and a mobile vehicle. The carrying platform 3 is fixed on the mobile vehicle. The first steel rail and the second steel rail are parallel to the railway track. The mobile vehicle is slidably disposed on the first steel rail. The second steel rail is disposed on the ground below the second top beam 104. The bottom of the telescopic column 101 under the second top beam 104 is provided with a roller, and the roller is rollingly disposed on the second steel rail. When the loading and unloading position of the railway container flat car 7 and the loading and unloading position of the container lorry are not in the same place, the two-way side pick-up device 4, the lifting device 2 and the container handling device 1 are moved along the first steel rail and the second steel rail by the moving vehicle, so as to complete container transfer operations at different locations.

[0077] The operating principle of the container rail-road transfer system is described in the following.

[0078] A container 6 being transferred from a container lorry to a railway container flat car 7 is taken as an example to describe the operating principle. After the container lorry enters a parking position between the first top beam 103 and the second top beam 104 of the container handling device 1, the telescopic columns 101 are retracted synchronously, so that the spreader 106 is lowered to a height that fits with the corner fittings on the top of the container 6. After the spreader 106 locks the container 6, the telescopic columns 101 lift the container 6; the bridging mechanism 402 of the two-way side pick-up device 4 is extended and pressed on the support beam of the container handling device 1, and the tray mechanism 401 is extended and located on the bridging mechanism 402; the telescopic columns 101 place the container 6 between the limit guide stops 4012 of the tray mechanism 401, and the spreader 106 is unlocked from the container 6; the spreader 106 rises, and the tray mechanism 401 retracts to its initial position, and the bridging mechanism 402 also retracts to its initial position. Then, the moving vehicle travels as needed to move the container 6 to the position corresponding to the railway container flat car 7. Afterwards, the bridging mechanism 402 extends to the railway container flat car 7 and presses on the top surface of the railway container flat car 7 (once the bridging mechanism 402 extends beyond the position of a central axis of the railway container flat car 7, the requirements to load the weight of the tray mechanism 401 and the container 6 can be met). The tray mechanism 401 slides on the bridging mechanism 402 to the railway container flat car 7 until the container 6 on the tray mechanism 401 is located right above the railway container flat car 7. At the same time, the lifting device 2 starts to act and slides the door-shaped support mechanisms along the second track 206, and then slides the door-shaped support mechanisms along the first track 205, so that the container twist lock parts 204 on the door-shaped support mechanisms can correspond to the positions of the corner fittings on the top of the container 6. The second telescopic legs 202 are extended to fix the second telescopic legs 202 on the ground on a side of the railroad track; and then the tray mechanism 401 slides on the bridging mechanism 402 toward the railway container flat car 7, until the container 6 on the tray mechanism 401 is located right above the railway container flat car 7. The door-shaped leg mechanisms are retracted so that the container twist lock parts 204 after being lowered can be locked with the corner fittings on the top of the container 6, and then the door-shaped support mechanisms extend to lift the container 6. After that, the tray mechanism 401 and the bridging mechanism 402 are retracted to their initial positions respectively. Finally, the door-shaped support mechanisms are retracted so that the container 6 can be placed on the railway container flat car 7, and the container twist lock parts 204 and the container 6 are unlocked.

[0079] In addition, when the container 6 is transferred from the railway container flat car 7 to the container lorry, the operating principle is contrary to the above process and will not be described in detail.

It should be understood that the detailed description and the specific examples are given by way of illustration only and are not intended to limit the present disclosure. Any changes, equivalent substitutions and modifications etc. within the spirit and principle of the present disclosure are still within the scope of the present disclosure.
