Description

BACKGROUND OF THE INVENTION

Field of the Invention

[0001] The present disclosure relates to a safety device for an electric locomotive platform capable of maintaining an interval between ropes and, more particularly, to a safety device for an electric locomotive platform capable of minimizing an occurrence of a safety accident by maintaining a vertical interval of ropes.

Description of the Related Art

[0002] In general, as shown in FIGS. 1 and 2, a safety device for an electric locomotive platform includes: at least one pair or more of lift driving units 10 installed at a selected position between an entrance of a platform to which an electric locomotive enters and an exit of the platform; movement bodies 20 on opposite sides of the ropes and each provided on an inner side of each of a pair of lift driving units 10 and each moved in an up-and-down (i.e., vertical) direction by each of the lift driving units 10; and a plurality of ropes 30 connecting the movement bodies 20 on the opposite sides of the ropes 30 to each other in a horizontal direction. This device is capable of blocking passage by lowering the ropes 30 when passengers are waiting on a platform (see FIG. 1), and allowing the passage by raising the ropes 30 when the passengers are on board an electric locomotive (see FIG. 2).

[0003] However, in such a safety device for the electric locomotive platform, when a passenger grabs and shakes a rope 30, the rope 30 is twisted, or deformation in which an interval between the ropes 30 is widened easily occurs, whereby there is a problem in that a hand or a body part of the passenger may easily pass through the interval between the ropes. In addition, while moving up and down, when the ropes 30 collide with a passenger or an obstacle, serious injury or damage may be caused. In addition, when any one of the ropes 30 is cut, tension of the remaining ropes may not be uniformly maintained, and thus passage of the passenger may not be blocked or allowed.

DETAILED DESCRIPTION OF THE INVENTION

[0012] Hereinafter, an exemplary embodiment of the present disclosure will be described with reference to the accompanying drawings.

[0013] A safety device for an electric locomotive platform according to the exemplary embodiment of the present disclosure may minimize an occurrence of a safety accident by maintaining a vertical interval of a rope as an interval that is set during manufacturing of the rope. Such a configuration of the safety device for the electric locomotive platform according to the exemplary embodiment of the present disclosure are shown in FIGS. 3 to 10.

[0014] Referring to FIGS. 3, 4, etc., the safety device for the electric locomotive platform according to the exemplary embodiment of the present disclosure includes: at least one pair or more of lift driving units 10 installed at a selected position between an entrance of a platform to which an electric locomotive enters and an exit of the platform; movement bodies 20 on opposite sides of the ropes and each moved in an up-and-down (i.e., vertical) direction by each of a pair of the lift driving units 10; a plurality of ropes 30 disposed at an interval so as to be spaced apart from each other in the up-and-down (i.e., vertical) direction between the lift driving units 10 that form a pair, and connecting the movement body 20 on the opposite sides to each other in a horizontal direction; and at least one or more of rope interval maintenance units 100 securing each interval of the plurality of ropes 30 by connecting the plurality of ropes 30 to each other in a vertical direction so as to suppress the plurality of ropes 30 from being deformed by an external force and suppress each interval of the plurality of ropes 30 from being changed.

[0015] The lift driving units 10 that form a pair may be disposed at a regular distance so as to be spaced apart from each other along a longitudinal direction of the platform and may face each other. Each of the lift driving units 10 that form a pair may include a post constituting a main body. Each of the posts may be erected on the platform in the vertical direction and be formed to have a predetermined height. A driving mechanism for moving each of the movement bodies 20 of the opposite sides thereof in the vertical direction may be provided inside of each post. The driving mechanism may be applied in various configurations such as a combination of a chain and sprocket with a motor, and a combination of a cylinder or screw jack with a motor.

[0016] The ropes 30 are coated with a rubber or synthetic resin material on an outer side thereof to prevent decay, as well as to minimize injury when colliding with a passenger.

[0017] The rope interval maintenance unit 100 connects the ropes 30 to each other in the vertical direction to secure the vertical interval of the ropes 30, thereby serving to prevent the ropes 30 from being deformed by a passenger who holds the rope 30 to twist the rope 30 or widen the interval between the ropes 30.

[0018] Referring to FIGS. 5 to 8, such a rope interval maintenance unit 100 includes: a fixing part 110 provided to fix the ropes 30 to each other in the vertical direction; a first buffer part 120 fixing a rope at the lowest position of the ropes 30 to a lower part of the fixing part 110 to be able to perform a buffer function in an event of colliding with a passenger or an obstacle; and a second buffer part 130 fixing a rope at the highest position of the ropes 30 to an upper part of the fixing part 110 to be able to perform the buffer function in the event of colliding with a passenger or an obstacle.

[0019] The fixing part 110 is provided with a pair thereof positioned in the front and rear of the ropes 30 and the pair is firmly fastened to each other by fasteners 112 such as bolts and nuts, so that, excluding the uppermost and lowermost ropes among the ropes 30, the remaining ropes positioned therebetween are pressed, thereby preventing deformation in which the ropes 30 are twisted by an external force or the interval between the ropes 30 is widened, thereby being able to maintain the vertical interval constant. The pair of fixing parts 110 may be provided with a pressure groove 111 into which the ropes 30 are inserted. Such a pair of fixing parts 110 may be provided in a bar shape by using a hard material such as a synthetic resin material.

[0020] As shown in FIG. 4, since the pair of fixing parts 110 connects the ropes 30 to each other in the vertical direction to secure the vertical interval of the ropes 30, tension of the remaining ropes is maintained even when some of the ropes are cut among the ropes 30, so as to be able to continue to block or allow the passage of the passenger.

[0021] The first buffer part 120 and the second buffer part 130 perform the buffer function in the event when the ropes 30 moving in the vertical direction collide with a passenger or an obstacle, thereby preventing the injury or damage from occurring. As shown in FIGS. 9 and 10, the first buffer part 120 and the second buffer part 130 may include buffer spaces 121 and 131 each inside of the first buffer part 120 and the second buffer part 130 each provided with the lowermost and uppermost ropes among the ropes 30 passing in the horizontal direction and formed to cushion a collision in the vertical direction in the event of colliding with a passenger or an obstacle. That is, the buffer spaces 121 and 131 are each provided with a certain space so that the lowermost and uppermost ropes 30 may be shaken in the vertical direction without fixing the lowermost and uppermost ropes 30, thereby performing the buffer function in the event of colliding with a passenger or an obstacle while the ropes are moving.

[0022] The first buffer part 120 and the second buffer part 130 are configured to entirely surround the outer diameters of the lowermost and uppermost ropes 30 respectively, and are made of a soft material, thereby minimizing injury caused by an event of colliding with a passenger.
