Description

Technical Field

[0001] This utility model relates to the field of transportation platforms, specifically to a rail transit platform. Background Technology

[0002] Rail transit platforms are mainly divided into island platforms and side platforms. Island platforms have the tracks on both sides and the platform in the middle, maximizing space utilization and facilitating transfers. Side platforms have the tracks in the center and the platform on both sides, offering a compact design suitable for city centers. In addition, there are also special platform designs such as hybrid, one-island-two-sides, three-island, double-island, and stacked island platforms.

[0003] A search revealed that CN220395311U discloses a rail transit platform, including a base. A column is fixedly connected to the center of the top of the base, and a canopy is fixedly connected to the top of the column. Several limiting components are embedded in the top of the base. Each limiting component includes a frame, with mounting slots at both ends inside the frame. A motor is fixedly connected to one side of the outer wall of the frame. The motor drive shaft passes through the frame and is fixedly connected to a railing. Sliding grooves are provided on both sides of the railing. An electromagnet is fixedly connected to the top of each sliding groove, and a limiting rod is provided inside the sliding groove.

[0004] The aforementioned rail transit platform, through the cooperation between the base, railings, and motor, and by setting up movable railings on the platform, facilitates the flexible boarding and alighting of passengers when there are few passengers, and facilitates the rapid formation of pedestrian passages during peak travel periods, allowing passengers to line up along the railings and move in an orderly manner.

[0005] When there are few tourists, this design uses a motor and electromagnet to lower the limiting bar used to form a queuing channel into the base to keep the upper part of the base flat. However, the drawback of this design is that after the limiting bar is lowered into the base, the top of the limiting bar is at the same height as the base. As a result, passengers will continuously step on the top of the limiting bar. This not only makes the limiting bar easy to accumulate a lot of dirt, but the dirt will also soil the clothes of tourists when the limiting bar is raised. At the same time, the lowered limiting bar is also prone to wear and tear during the stepping of passengers, thus reducing its service life. Utility Model Content

[0006] This utility model proposes a rail transit platform that solves the problems of existing technology, which not only makes the limit bar easy to accumulate a lot of dirt, but also makes the dirt dirty the clothes of tourists when the limit bar is raised. At the same time, the recessed limit bar is also prone to wear and tear during the process of passengers stepping on it, thus reducing its service life.

[0007] The technical solution of this utility model is as follows: A rail transit platform includes a platform roof. A linkage component is installed inside the platform roof. Two sets of driven components are also arranged in parallel inside the platform roof. Each driven component includes a bidirectional screw that can rotate forward and backward with the linkage component. Two sets of guardrail components are symmetrically arranged on one side of each driven component. Each guardrail component includes a rotating arm that can rotate 90 degrees with the driven component. The guardrail component also includes an elastic rope that can form a protective enclosure between the two sets of rotating arms on one side.

[0008] Preferably, the linkage component includes two sets of rotating shafts, which are parallel and rotatably connected to the inner groove of the platform roof. Each rotating shaft is fixedly connected to each bidirectional screw. The linkage component also includes a forward and reverse motor, which is fixedly installed on the outside of the platform roof. The output end of the forward and reverse motor is fixedly connected to one of the rotating shafts.

[0009] Preferably, the linkage assembly further includes a timing pulley, each timing pulley being fixedly connected to the outside of each rotating shaft, and the linkage assembly further includes a timing belt, which is sleeved on the outside of the two sets of timing pulleys and the timing belt and timing pulleys are meshed and connected.

[0010] Preferably, the driven component includes two sets of slides, which are threadedly connected to opposite threads on both sides of the bidirectional screw. The driven component also includes a toothed groove group, which is formed at the bottom of the slide side.

[0011] Preferably, the driven component further includes a connecting rod, which is rotatably connected inside the platform roof. One end of the connecting rod is fixedly connected to the rotating arm, and the other end of the connecting rod is fixedly connected to a gear plate, which is in meshing contact with the tooth groove group.

[0012] Preferably, the guardrail assembly further includes a telescopic rod, the fixed end of which is fixedly connected to the rotating arm.

[0013] Preferably, the telescopic rod has a rotating bead connected to its telescopic end, and two sets of rotating beads on one side are fixedly connected to both ends of the elastic rope.

[0014] Preferably, the guardrail assembly further includes an infrared detection element, which is fixedly installed on the outside of the swing arm.

[0015] The beneficial effects of this utility model are as follows:

[0016] This invention places the guardrail assembly for forming a queuing channel inside the platform canopy. When the passenger flow on the platform below the canopy is large and it is necessary to classify and queue passengers in an orderly manner, the forward and reverse motors can be started to drive the rotating shaft to rotate. With the cooperation of the synchronous pulley and synchronous belt, the two sets of bidirectional screws rotate synchronously in the same direction. At this time, the slides threaded to the opposite threads on both sides of the bidirectional screws move horizontally in opposite directions and drive the gear plate to rotate through the toothed groove group. At this time, each rotating arm and telescopic rod rotates synchronously with the gear plate to vertically downward. At this time, the elastic rope between the two sets of rotating balls on both sides forms a guardrail channel for passengers to queue and board the vehicle. Compared with the prior art, this design effectively reduces the problem of guardrail assembly being stepped on by passengers, which causes dirt to adhere or even be damaged.

The guardrail components 4 include a rotating arm 41 that can rotate 90 degrees with the driven component 3. The guardrail components 4 also include an elastic rope 43 that can form a enclosure between the two sets of rotating arms 41 on one side.

[0025] This design solves the problems of existing technology, which not only makes the limit bar prone to accumulating a lot of dirt, but also makes the dirt dirty when the limit bar is raised and soils the tourists' clothes. At the same time, the recessed limit bar is also prone to wear and tear during the stepping of passengers, thus reducing its service life.

[0026] Please see Figure 2 The linkage component 2 includes two sets of rotating shafts 22, which are parallel and rotatably connected to the inner groove of the platform roof 1. Each rotating shaft 22 is fixedly connected to each bidirectional screw 31. The linkage component 2 also includes a forward and reverse motor 21, which is fixedly installed on the outside of the platform roof 1. The output end of the forward and reverse motor 21 is fixedly connected to one of the rotating shafts 22. The linkage component 2 also includes a synchronous pulley 221, which is fixedly connected to the outside of each rotating shaft 22. The linkage component 2 also includes a synchronous belt 23, which is sleeved on the outside of the two sets of synchronous pulleys 221 and is meshed with the synchronous pulleys 221.

[0027] This design allows the two sets of rotating shafts 22 to rotate synchronously and in the same direction within the platform canopy 1.

[0028] Please see Figure 3 The driven component 3 includes two sets of slides 32, which are threadedly connected to opposite threads on both sides of the bidirectional screw 31. The driven component 3 also includes a toothed groove group 321, which is opened at the bottom of the slide 32. The driven component 3 also includes a connecting rod 33, which is rotatably connected inside the platform canopy 1. One end of the connecting rod 33 is fixedly connected to the rotating arm 41, and the other end of the connecting rod 33 is fixedly connected to a toothed disc 331. The toothed disc 331 and the toothed groove group 321 are in meshing contact.

[0029] When each shaft 22 rotates, the bidirectional screw 31 connected to each shaft 22 will rotate synchronously inside the platform roof 1. At this time, the slide blocks 32 threaded to the opposite threads on both sides of the bidirectional screw 31 will move synchronously towards each other, and drive the gear plate 331 meshing below the gear plate 321 to rotate synchronously through the gear groove group 321. At this time, the connecting rod 33 fixedly connected to one end of the gear plate 331 and the rotating arm 41 will rotate synchronously.

[0030] Please see Figure 3 and Figure 4 The guardrail assembly 4 also includes a telescopic rod 42, the fixed end of which is fixedly connected to the rotating arm 41;

[0031] The telescopic rod 42 has a rotating bead 421 rotatably connected to its telescopic end, and two sets of rotating beads 421 on one side are fixedly connected to the two ends of the elastic rope 43.

[0032] The guardrail assembly 4 also includes an infrared detection element 411, which is fixedly installed on the outside of the rotating arm 41;

[0033] The telescopic rod 42 and the infrared detection element 411 are both connected to the external control system to enable the infrared detection element 411 to detect people walking below and the telescopic rods 42 to extend and retract synchronously.

[0034] The working principle and usage process of this utility model are as follows:

[0035] This design places the guardrail assembly 4, used to form a queuing channel, inside the platform canopy 1. When the passenger flow on the platform below the canopy 1 is large and it is necessary to classify and queue passengers in an orderly manner, the forward and reverse motor 21 can be started to drive the rotating shaft 22 to rotate. With the cooperation of the synchronous pulley 221 and the synchronous belt 23, the two sets of bidirectional screws 31 rotate synchronously in the same direction. At this time, the slides 32 threaded to the opposite threads on both sides of the bidirectional screws 31 move horizontally in opposite directions and drive the toothed disc 331 to rotate through the toothed groove group 321. At this time, each rotating arm 41 and the telescopic rod 42 rotate synchronously with the toothed disc 331 to a vertical downward position. At this time, the elastic rope 43 between the two sets of rotating beads 421 on both sides forms a guardrail channel for passengers to queue and board the vehicle. Compared with the prior art, this design effectively reduces the problem of guardrail assembly 4 being stepped on by passengers, which causes dirt to adhere or even be damaged.
