Description

Slide Module Barrier Rope Clamping Device Technical Field

[0001] This application belongs to the field of clamping device technology, and specifically relates to a sliding table module barrier rope clamping device. Background Technology

[0002] In the field of rail transit platform safety protection, rope-operated platform screen doors achieve stable opening and closing of the doors by controlling the barrier ropes, making them a core piece of equipment for ensuring passenger safety. To prevent the exposed clamping mechanism from scratching passengers, existing technologies generally embed the barrier rope clamping device inside the doorpost, deeply integrating it with the door structure.

[0003] However, while this design meets the safety protection requirements, it has revealed some shortcomings in the maintenance process: First, the barrier rope is a vulnerable part that needs to be replaced regularly. The existing clamping mechanism is completely embedded inside the gatepost, and the replacement requires disassembling multiple layers of components such as the gatepost decorative panel and structural frame in sequence. The operation process is cumbersome, and a single replacement often takes several hours. Second, the space inside the gatepost is narrow, the disassembly tools are limited, and multiple people are required to complete the work, which increases labor costs.

[0004] In summary, while the existing barrier rope clamping device embedded in the gatepost meets the safety protection requirements, it is insufficient in terms of ease of replacement. There is an urgent need for an improved solution that can simplify the replacement process and reduce maintenance costs. Summary of the Invention

[0005] This application provides a clamping device that simplifies the replacement process and improves replacement efficiency, in order to solve the problem of low efficiency in replacing barrier ropes in existing barrier rope clamping devices.

[0006] To achieve the above objectives, this application provides a sliding table module barrier rope clamping device, including a protective housing, which is disposed on the sliding table module. A limit slide is slidably disposed inside the protective housing, and an adjusting spring is disposed between the limit slide and one side wall of the protective housing. A clamping mechanism is installed on the side of the limit slide away from the adjusting spring, and an adjusting rod is also disposed on the clamping mechanism. Limit grooves are formed on both side walls of the protective housing.

[0007] The clamping mechanism includes a housing, which is slidably disposed within a protective housing. Two mounting chambers are symmetrically fixedly disposed on the side of the housing near the limiting slide plate. Each mounting chamber contains a linkage component, which is connected by a connecting rod. Each linkage component has a connecting seat at both ends. A limiting slider is installed on the limiting slide plate, and the other end of the connecting seat is connected to the limiting slider via a connecting component. Slides are symmetrically provided through the inner wall of the mounting chamber, and the linkage components are slidably connected to the slides. A clamping component is disposed on the side of the housing away from the limiting slide plate. An adjusting rod is also connected to one of the linkage components.

[0008] In one embodiment, the linkage component includes a first link, the central axis of which is rotatably disposed within the mounting chamber, and a second link rotatably disposed at both ends of the first link. A slide is rotatably disposed at the other end of the second link, the two slides are slidably connected to the slide rail, and a connecting seat is fixedly disposed on the slide.

[0009] In one embodiment, the central axes of the two first links are connected by a connecting rod.

[0010] In one embodiment, the adjusting rod is rotatably mounted on the connecting shaft between the first link and the second link.

[0011] In one embodiment, the limiting slide plate includes a limiting plate, which is slidably disposed within the protective housing, and a mounting plate is fixedly disposed on the side of the limiting plate away from the adjusting spring corresponding to the connecting seat;

[0012] The connecting assembly includes an upper slide and a lower slide. The upper slide is located on the upper end of the mounting plate near the connecting seat, and the lower slide is located on the lower end of the mounting plate away from the connecting seat. A mounting groove is also provided through the mounting plate. A rotating rod is rotatably installed in the mounting groove. One end of the lower slide and one end of the upper slide are slidably installed at the two ends of the rotating rod, respectively. A limit slider is rotatably installed at the other end of the lower slide, and the limit slider is slidably installed in the lower slide.

[0013] The other end of the upper slide rod slides against the upper slide table.

[0014] In one embodiment, a return spring is provided between the upper slide rod on the side away from the connecting seat and the mounting plate.

[0015] In one embodiment, a T-slot is formed in the lower slide platform, and the limiting slider is slidably engaged in the T-slot.

[0016] In one embodiment, the clamping assembly includes a track fixedly disposed within a housing, and two clamping members slidably disposed within the track, the clamping members being connected by bolts.

[0017] In one embodiment, a pull ring is also provided on the track.

[0018] Compared with the prior art, the beneficial effects of this application are:

[0019] The coordinated design of the protective shell, limiting slide plate, adjusting spring, clamping mechanism, and linkage components significantly simplifies the barrier rope replacement process. Pulling the adjusting rod drives the linkage component, disengaging the connecting seat from the limiting slide plate's slot, allowing easy removal of the clamping mechanism for barrier rope replacement. This avoids the cumbersome steps of traditional replacement methods and greatly improves replacement efficiency. The rotational engagement of the first and second connecting rods and the synchronous connection design of the connecting rod in the linkage component ensure synchronous movement of the connecting seat, preventing operational deviations caused by unilateral separation and improving the stability and reliability of the device. The limiting slide plate, through the linkage structure of the rotating rod, lower sliding rod, upper sliding rod, and limiting slider, engages with the limiting slider in the limiting groove of the protective shell when unlocked, preventing movement of the limiting slide plate and ensuring a stable replacement operation. Upon relocking, it automatically returns to its original position, and combined with the reset action of the adjusting spring, ensures the device's stability, reliability, and convenient and efficient operation. Furthermore, the continuous adjustment of the barrier rope tension by the adjusting spring prevents loosening or excessive tension during long-term use, extending the barrier rope's lifespan, reducing maintenance frequency, and effectively improving the overall working efficiency and safety of the equipment.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0031] Referring to Figures 1 to 8, the slide module barrier rope clamping device provided in this application includes a protective housing 1, which is disposed on the slide module. A limiting slide plate 2 is slidably disposed inside the protective housing 1. An adjusting spring 3 is disposed between the limiting slide plate 2 and one side wall of the protective housing 1. A clamping mechanism 4 is installed on the side of the limiting slide plate 2 away from the adjusting spring 3. An adjusting rod 5 is also disposed on the clamping mechanism 4. Limit grooves 7 are formed on both side walls of the protective housing 1.

[0032] When replacing the barrier rope, the operator first pulls the clamping mechanism 4 to slide it inside the protective housing 1. During the sliding process, the clamping mechanism 4 causes the limiting slide plate 2 to slide synchronously. When the clamping mechanism 4 slides to the preset maintenance position, the limiting slide plate 2 is locked by the limiting groove 7. At the same time as the limiting slide plate 2 is locked, the adjusting rod 5 is pulled, so that the clamping mechanism 4 is released from the limitation of the limiting slide plate 2. At this time, the clamping mechanism 4 can be easily removed from the protective housing 1 for the replacement of the barrier rope. This avoids the cumbersome steps of the traditional barrier rope replacement and significantly improves the replacement efficiency.

[0033] After the clamping mechanism 4 secures the new barrier rope, it is reinserted into the protective housing 1. The clamping mechanism 4 is then pushed to re-engage with the limiting slide plate 2. Finally, the adjusting rod 5 is pulled to reset the position, restoring the locking state between the limiting slide plate 2 and the clamping mechanism 4. Simultaneously, after the limiting slide plate 2 and the clamping mechanism 4 are locked, the constraint of the protective housing 1 on the limiting slide plate 2 is released. Finally, under the action of the adjusting spring 3, the limiting slide plate 2 automatically returns to its original position, completing the entire replacement process. This ensures the device is stable and reliable, and the operation is simple and efficient, effectively shortening the barrier rope replacement time and improving the convenience and safety of equipment maintenance.

[0034] The clamping mechanism 4 includes a housing 41, which is slidably disposed within a protective housing 1. Two mounting chambers 42 are symmetrically fixed on the side of the housing 41 near the limiting slide plate 2. Each mounting chamber 42 contains a linkage component 43, which is connected by a connecting rod 434. Each linkage component 43 has a connecting seat 46 at both ends. A limiting slider 25 is mounted on the limiting slide plate 2, and the other end of the connecting seat 46 is connected to the limiting slider 25 via a connecting component. Slide tracks are symmetrically formed through the inner wall of the mounting chamber 42, and the linkage components 43 are slidably connected to these tracks. A clamping component 45 is disposed on the side of the housing 41 away from the limiting slide plate 2. An adjusting rod 5 is also connected to one of the linkage components 43.

[0035] Specifically, during the replacement of the barrier rope, the clamping assembly 45 is first pulled to cause the outer casing 41 to slide outward within the protective casing 1. When the outer casing 41 slides to the preset maintenance position, the adjusting rod 5 is pulled, causing the linkage assembly 43 connected to it to drive the connecting seats 46 at both ends to move closer together. At the same time, the linkage assembly 43 drives another linkage assembly 43 to move through the connecting rod 434, causing the other linkage assembly 43 to drive the connecting seats 46 at both ends to move closer together. During this movement, when the connecting seats 46 are completely disengaged from the connecting assembly, the outer casing 41 can be released from the constraint of the limiting slide plate 2, at which point the outer casing 41 can be easily removed for barrier rope replacement.

[0036] Meanwhile, after the connecting seat 46 is completely detached from the connecting assembly, the limiting slider 25 connected to the connecting assembly will slide into the limiting groove 7 opened on the side wall of the protective housing 1, so that the limiting slider 25 and the limiting groove 7 in the protective housing 1 are engaged, ensuring that the limiting slide plate 2 will not move during the removal of the housing 41, and further stabilizing the entire replacement operation.

[0037] After replacing the barrier rope, reinstall the outer casing 41 back into the protective casing 1, push the outer casing 41 to re-engage with the limiting slide plate 2, and reset the linkage component 43 by adjusting the pull rod 5, so that the connecting seat 46 reconnects with the connecting component, restoring the initial locking state and ensuring a stable connection between the limiting slide plate 2 and the outer casing 41. The limiting slider 25 connected to the connecting component will disengage from the limiting groove 7, thereby releasing the engagement between the limiting slider 25 and the limiting groove 7, releasing the constraint of the protective casing 1 on the limiting slide plate 2, and finally, under the action of the adjusting spring 3, the limiting slide plate 2 automatically returns to its original position.

[0038] This design not only simplifies the operation process but also maintains the adjustment of the tension of the barrier rope by the adjusting spring 3 after replacement, avoiding loosening or excessive tightness during long-term use, extending the service life of the barrier rope, reducing maintenance frequency, and improving overall work efficiency.

[0039] Optionally, the linkage assembly 43 includes a first connecting rod 431, the central axis of which is rotatably mounted within the mounting chamber 42. Second connecting rods 432 are rotatably mounted at both ends of the first connecting rod 431, and a slide block 433 is rotatably mounted at the other end of each second connecting rod 432. The two slide blocks 433 are slidably connected to the slide rail, and a connecting seat 46 is fixedly mounted on the slide blocks 433. The central axes of the two first connecting rods 431 are connected by a connecting rod 434, and an adjusting rod 5 is rotatably mounted on the connecting shaft between the first connecting rod 431 and the second connecting rod 432.

[0040] In this embodiment, when the adjusting lever 5 is pulled, the connecting shaft between the first connecting rod 431 and the second connecting rod 432 connected to it rotates, thereby causing the first connecting rod 431 to rotate around the central axis and drive the second connecting rods 432 at both ends to rotate synchronously, thereby pushing the slide block 433 to move smoothly along the slide rail. During the sliding process, the slide block 433 ensures the synchronous movement of the two connecting seats 46, avoids the operation deviation caused by unilateral separation, ensures the coordination and consistency of the entire replacement process, and improves the overall stability and reliability of the device.

[0041] Optionally, the limiting slide plate 2 includes a limiting plate 21, which is slidably disposed within the protective housing 1. A mounting plate 22 is fixedly disposed on the side of the limiting plate 21 away from the adjusting spring 3, corresponding to the connecting seat 46. The connecting assembly includes an upper slide 23 and a lower slide 24. The upper slide 23 is disposed on the upper end of the mounting plate 22 near the connecting seat 46, and the lower slide 24 is disposed on the lower end of the mounting plate 22 away from the connecting seat 46. A mounting groove 210 is also provided through the mounting plate 22. A rotating rod 26 is rotatably disposed within the mounting groove 210. A lower slide rod 27 and an upper slide rod 28 are slidably disposed at both ends of the rotating rod 26, respectively. A limiting slider 25 is rotatably disposed at the other end of the lower slide rod 27. The limiting slider 25 is slidably disposed within the lower slide 24, and the other end of the upper slide rod 28 slidably abuts against the upper slide 23.

[0042] A return spring 29 is provided between the upper slide rod 28 on the side away from the connecting seat 46 and the mounting plate 22.

[0043] In this embodiment, the connecting seat 46 can slide within the upper slide table 23. When the locking state between the limiting slide plate 2 and the outer shell 41 is released, the two connecting seats 46 move closer to each other, causing the connecting seats 46 to slide in the direction of moving away from the upper slide table 23, thereby gradually releasing the constraint on the upper slide rod 28. During this process, the return spring 29 gradually releases its elastic force. The return spring acts on the upper slide rod 28, thereby driving the rotating rod 26 to start rotating. Then, the rotating rod 26 pushes the lower slide rod 27 to make the limiting slider 25 move along the lower slide table 24. As the limiting slider 25 gradually moves out of the lower slide table 24, the limiting slider 25 will gradually engage into the limiting groove 7. When the connecting seat 46 is completely separated from the upper slide table 23, the limiting slider 25 is completely engaged into the limiting groove 7. This achieves the relative fixation of the limiting plate 21 and the protective shell 1 while the locking state between the limiting plate 21 and the outer shell 41 is released, avoiding displacement under the action of the adjusting spring 3, ensuring the stable positioning of the limiting plate 21, and further improving the safety and ease of operation of the device.

[0044] Conversely, when relocking is required, the operation is reversed. The two connecting seats 46 move away from each other, causing them to gradually return to the upper slide table 23. This applies pressure to the upper slide rod 28, causing it to slide. The return spring 29 gradually compresses the upper slide rod 28, while the upper slide rod 28 causes the rotating rod 26 to rotate in the opposite direction. This drives the lower slide rod 27 to move the limiting slider 25 back along the lower slide table 24 until the limiting slider 25 moves out of the limiting groove 7 and re-engages in the lower slide table 24, thus releasing the relative fixation between the limiting plate 21 and the protective shell 1. At the same time, in this state, the connecting seat 46 will slide back to its initial position, meaning the limiting plate 21 and the shell 41 are relocked, making them a single unit. This ingenious mechanical linkage design not only simplifies the operation process but also significantly improves the efficiency and safety of replacing the barrier rope.

[0045] In practical applications, after relocking is completed, the limiting plate 21 will automatically return to its original position under the action of the adjusting spring 3, so that the limiting slider 25 cannot slide under the action of the protective housing 1, thereby forming a stable locking state, ensuring that the housing 41 and the limiting plate 21 are tightly fitted, and preventing accidental loosening.

[0046] An avoidance groove is also provided on the limiting plate 21. The avoidance groove can prevent the first link 431 and the second link 432 from interfering with the inner wall of the limiting plate 21 during the movement, thereby ensuring the continuity of the movement.

[0047] Optionally, a T-slot is provided in the lower slide table 24, and the limiting slider 25 is slidably engaged in the T-slot to ensure that the limiting slider 25 moves accurately in the T-slot and prevents it from deviating from the track of the lower slide table 24.

[0048] Optionally, the clamping assembly 45 includes a track 451, which is fixedly disposed inside the housing 41. Two clamping members 452 are slidably disposed inside the track 451 and are connected by bolts 454.

[0049] In this embodiment, during the replacement of the barrier rope, the connection relationship of the clamping member 452 is resolved by the bolt member 454. The clamping member 452 is moved along the track 451 so that the two clamping members 452 are far apart. Then, the barrier rope is inserted between the two clamping members 452. The two clamping members 452 are then moved closer to each other along the track 451 to clamp the barrier rope. Finally, the two clamping members 452 are fixed to each other by the bolt member 454 to securely clamp the barrier rope and ensure that the barrier rope is tightly clamped.

[0050] Optionally, a pull ring 453 is also provided on the track 451. The pull ring 453 facilitates the movement of the housing 41 within the protective housing 1.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
