Coupled with its core advantages of economy and convenience, railways have become the preferred mode of travel for the vast majority of passengers. However, the continuous growth in passenger traffic and the diversification of travel demands have also brought severe challenges to railway passenger transport departments: the difficulty of guiding passenger flow has increased, and the pressure on platform safety management has become prominent. Strengthening safety precautions and improving operational efficiency have become important directions for the industry's development. Summary of the Invention

[0003] To address the above problems, the present invention provides a channel lifting safety protection device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A channel lifting safety protection device includes two left and right column assemblies and multiple isolation strips connected between the two column assemblies. Each column assembly includes a housing column and a power traction system disposed on the housing column. The multiple isolation strips are moved up and down under the action of the power traction system disposed in the column assembly. Both ends of each isolation strip are connected to the column assembly through an isolation strip sliding mechanism. The isolation strip sliding mechanism includes a slider, which is slidably disposed on a guide rail located inside the housing column. The end of each isolation strip is connected to one end of a connecting rod through a clamping assembly. The other end of the connecting rod is connected to a tensioning mechanism disposed on the outer side of the slider. Track grooves are formed on the opposite sides of the two housing columns, and the tensioning mechanism passes through the track grooves.

[0005] Furthermore, the safety protection device also includes a blocking assembly that sequentially blocks the multiple sliders from top to bottom. The blocking assembly includes multiple slider blocking blocks spaced from top to bottom on the inner side of the housing column located on one side of the guide rail, and a blocked block on the side of each slider near the slider blocking block. The length of the multiple slider blocking blocks arranged from top to bottom increases sequentially in the direction parallel to the top surface of the housing column, and the length of the multiple blocked blocks decreases sequentially in the direction parallel to the top surface of the housing column, so that the slider blocking blocks block the blocked blocks arranged in the same order from top to bottom.

[0006] Furthermore, the clamping assembly includes a large clamping block and a small clamping block connected to the end of the isolation strip. The small clamping block is connected to the isolation strip and is engaged with the large clamping block. A protruding buckle is provided on the side of the large clamping block away from the isolation strip. The protruding buckle is inserted and locked with a clamping buckle. The connecting rod is fixedly connected to the clamping buckle.

[0007] Furthermore, the tensioning mechanism includes a clamping seat, which is fixed to the outer surface of the slider. Two vertically arranged clamping plates are provided on the outer surface of the clamping seat away from the slider, spaced apart horizontally. The connecting rod passes through the two clamping plates and is fixedly connected to them. Two guide shafts are provided vertically between the two clamping plates, and springs are passed through the two guide shafts. The connecting rod is located between the two springs.

[0008] Furthermore, limiting components are provided at both the top and bottom of the guide rail. Each limiting component includes a guide rail end pressure block and a limiting switch plate. The guide rail end pressure block is fixedly connected to the guide rail, and the limiting switch plate is fixed to the outer surface of the guide rail end pressure block. A limiting switch is provided on the limiting switch plate, and the limiting switch is controlled and connected to the power traction system through a control system.

[0009] Furthermore, the power traction system includes an active end and a driven end respectively located at the upper and lower ends of the housing column. The active end includes the main motor and the active wheel. The main motor drives the active wheel to rotate through a reducer. The driven end includes a driven wheel rotatably disposed at the lower part of the housing column (a driven wheel seat is mounted on the inner bottom surface of the lower end of the housing column, and the driven wheel is rotatably disposed on the driven wheel frame through a driven wheel shaft). A synchronous belt is wound between the active wheel and the driven wheel, and a synchronous belt buckle is provided on the synchronous belt for pulling a slider connected to the lowermost isolation belt.

[0010] Furthermore, a threaded rod is vertically inserted through the bottom wall of the housing column, and a timing belt tensioner with internal threads is fixed below the driven wheel, with the threaded rod screwed to the timing belt tensioner.

[0011] Furthermore, the safety protection device also includes a secondary power traction system, which includes a secondary motor at the top of the housing column and a bottom slider slidably mounted on the guide rail. The secondary motor is connected to a winch wheel via a second reducer, and a winch rope is wound around the winch wheel. The winch rope is connected to the bottom slider.

[0012] Furthermore, a rope release limit is fixed on the side of the limit switch plate near the winch rope.

[0013] Furthermore, the column assembly also includes an upper foreign object sensor, a lower foreign object sensor, and a voice speaker. The upper and lower foreign object sensors are connected to the main motor, the auxiliary motor, and the voice speaker via a control system.

[0014] The lifting safety protection device of this invention adopts modular physical isolation technology. Based on the arrival and departure times of trains, the lifting action of the safety equipment can be triggered in advance in manual / remote or automatic mode, creating a precisely linked isolation system between the waiting hall and the platforms of trains arriving and departing on the same day. This design enables directional connectivity between the waiting hall and designated line platforms, ensuring passengers accurately reach their corresponding boarding platforms while providing convenient passageways for transfer passengers.

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] like Figures 1-7 As shown, a channel lifting safety protection device includes two left and right column assemblies 1 and multiple isolation strips 2 connected between the two column assemblies 1. Each column assembly 1 includes a housing column 11 and a power traction system disposed on the housing column 11. The multiple isolation strips 2 are moved up and down under the action of the power traction system disposed in the column assembly 1. Both ends of each isolation strip 2 are connected to the column assembly 1 through an isolation strip sliding mechanism. The isolation strip sliding mechanism includes a slider 31, which is slidably disposed on a guide rail 12 located inside the housing column 11. The end of the isolation strip 2 is connected to one end of a connecting rod 32 through a clamping assembly. The other end of the connecting rod 32 is connected to a tensioning mechanism disposed on the outer side of the slider 31. Track grooves 111 are opened on the opposite sides of the two housing columns 11, and the tensioning mechanism passes through the track grooves.

[0025] In some embodiments, the safety protection device further includes a blocking assembly that sequentially blocks the plurality of sliders 31 from top to bottom. The blocking assembly includes a plurality of slider blocking blocks 51 spaced from top to bottom on the inner side of the housing column 11 located on one side of the guide rail 12, and a blocked block 52 disposed on the side of each slider 31 near the slider blocking block 51. The length of the plurality of slider blocking blocks 51 arranged from top to bottom increases sequentially in the direction parallel to the top surface of the housing column 11, and the length of the plurality of blocked blocks 52 decreases sequentially in the direction parallel to the top surface of the housing column 11, so that the slider blocking blocks 51 block the blocked blocks 52 arranged in the same order from top to bottom.

[0026] like Figure 4As shown, the uppermost slider block from top to bottom includes a block body 511 and a baffle post 512 located on the upper surface of the block body 511, as follows: Figure 5 As shown, the uppermost partition block is L-shaped, the partition part 521 is located to the left of the slider 31, and the fixing part 522 is located in front of the slider 31. During the downward movement of the isolation strip 2, the lower part of the partition part 521 abuts against the top of the partition post 512. The lengths of the other partition block bodies 511 arranged sequentially from top to bottom in the direction parallel to the top surface of the housing column 11 increase sequentially, while the lengths of the other partition parts 521 arranged sequentially from top to bottom in the direction parallel to the top surface of the housing column 11 decrease sequentially.

[0027] It is understandable that the partition blocks 52 among the multiple sliders 31 from top to bottom will achieve precise limiting cooperation with the multiple slider partition blocks 51 of the same order from top to bottom during the falling stroke. The purely mechanical blocking structure ensures that each slider 31 is stably maintained at the preset working height, thus ensuring the positional accuracy and reliability of the equipment operation.

[0028] Furthermore, the clamping assembly includes a large clamping block 41 and a small clamping block 42 connected to the end of the isolation strip 2. The small clamping block 42 is connected to the isolation strip 2 and is engaged with the large clamping block 41. The large clamping block 41 has a protruding buckle 411 on the side away from the isolation strip 2. The protruding buckle 411 is inserted and locked with a clamp 43. The connecting rod 32 is fixedly connected to the clamp 43.

[0029] With this configuration, the isolation belt 2 adopts a combination clamping structure of large clamping block 41 and small clamping block 42. The protruding buckle 411 of the large clamping block 41 and the clamping buckle 43 form a reliable locking fit, ensuring the stability and reliability of the connection between the isolation belt 2 and the equipment. At the same time, the top of the clamping buckle 43 has an open structure, which can realize quick unhooking operation and improve the convenience of assembly and maintenance.

[0030] Furthermore, the tensioning mechanism includes a clamping seat 33, which is fixed to the outer surface of the slider 31. Two vertically arranged clamping plates 36 are provided on the outer surface of the clamping seat 33 away from the slider 31. The connecting rod 32 passes through the two clamping plates 36 and is fixedly connected to them. Two guide shafts 34 are provided vertically between the two clamping plates 36. Springs 35 are passed through the two guide shafts 34. The connecting rod 32 is located between the two springs 35.

[0031] With this configuration, the clip 43 is rigidly connected to the clip plate 36 via the connecting rod 32. Guide shafts 34 are positioned on both sides of the assembly to provide precise guidance and constraint during movement. A spring 35 is added to the middle of the assembly, allowing the clip 43 to slide flexibly on the clip seat 33 and generate a stable elastic preload, thereby achieving the tensioning and locking function of the isolation strip 2. Even in installation scenarios with a large span of 10 meters, this elastic tensioning structure can effectively offset the effects of installation errors and environmental deformation, ensuring that the isolation strip maintains a reliable tension state over a long period, avoiding problems such as slackness or displacement.

[0032] Furthermore, limiting components are provided at both the top and bottom of the guide rail 12. Each limiting component includes a guide rail end pressure block 61 and a limit switch plate 62. The guide rail end pressure block 61 is fixedly connected to the guide rail 12, and the limit switch plate 62 is fixed to the outer surface of the guide rail end pressure block 61. A limit switch 63 is provided on the limit switch plate 62, and the limit switch 63 is controlled and connected to the power traction system through a control system.

[0033] Furthermore, the power traction system includes an active end and a driven end respectively located at the upper and lower ends of the housing column 11. The active end includes the main motor 71 and the active wheel 72. The main motor 71 drives the active wheel 72 to rotate through the reducer 76. The driven end includes a driven wheel 73 rotatably disposed at the lower part of the housing column 11. A driven wheel 73 seat is mounted on the inner bottom surface of the lower end of the housing column 11. The driven wheel 73 is rotatably disposed on the driven wheel frame 77 through a driven wheel shaft. A synchronous belt 74 is wound between the active wheel 72 and the driven wheel 73. A synchronous belt buckle 75 for pulling the slider 31 connected to the lowermost isolation belt 2 is provided on the synchronous belt 74.

[0034] Understandably, the main motor 71 provides power, which is converted by the reducer 76 and then drives the synchronous belt 74 through the driven wheel 73, thereby driving the lowermost slider to pull the isolation belt 2 to complete the lifting and lowering.

[0035] Furthermore, a threaded rod 13 is vertically inserted through the bottom wall of the housing column 11, and a synchronous belt tensioner 14 with internal threads is fixed below the driven wheel 73. The threaded rod 13 is screwed to the synchronous belt tensioner 14.

[0036] To enable a single column equipment to be equipped with two independent traction systems for dual power protection, the safety protection device also includes an auxiliary power traction system. The auxiliary power traction system includes an auxiliary motor 81 at the top of the housing column 11 and a bottom slider 82 slidably mounted on the guide rail 12. The auxiliary motor 81 is connected to a winch wheel 84 through a second reducer 83. A winch rope 85 is wound on the winch wheel 84 and is connected to the bottom slider 82.

[0037] It is understandable that the auxiliary motor 81 provides power, which is converted by the second reducer 83 and then drives the winch rope 85 through the winch wheel 84 to pull the bottom slider 82 to pull the isolation belt 2 to complete the lifting and lowering, thereby effectively controlling the lifting and lowering of the isolation belt 2.

[0038] The two power traction systems are equipped with two independent power control units. System 1 uses mains power for normal operation, while System 2 is equipped with a backup battery for emergency situations.

[0039] Understandably, the timing belt tensioner 13 applies tension to the driven pulley 73, ensuring sufficient tension on the timing belt 74 for better transmission of traction during power transmission. At the same time, the low-position limit switch 63 can also provide an accurate position signal when the bottom slider 82 is too low.

[0040] Furthermore, a rope-detachment limiter 86 is fixed on the side of the limit switch plate 62 near the winch rope.

[0041] Both power drive systems have comprehensive safety protection functions. When the top slider rises to an excessively high position, the limit switch 63 will be triggered, simultaneously protecting both System 1 and System 2 from overshoot risk during operation. Furthermore, if the traction rope shifts or becomes loose during the operation of System 2, it can be detected in time by the rope release limit 34, which will immediately stop the equipment and issue a fault warning.

[0042] Furthermore, the column assembly 1 also includes an upper foreign object sensor 14, a lower foreign object sensor 15, and a voice speaker 16. The upper foreign object sensor 14 and the lower foreign object sensor 15 are connected to the main motor 71, the auxiliary motor 81, and the voice speaker 16 via a control system.

[0043] Those skilled in the art should understand that the above description is merely a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
