[0002] As railway construction accelerates and the railway network becomes increasingly comprehensive, rail travel is becoming the choice for more and more people. To prevent passengers from falling onto the tracks from the platform and to further strengthen safety measures for passengers on the platform, more and more stations are beginning to install platform screen door protection devices.

[0003] Existing platform screen door safety devices generally use high-strength protective ropes as a barrier. Over time and due to changes in the rope's mechanical properties, the tension of the rope gradually decreases, causing it to sag noticeably and affecting the safe operation of the platform screen door safety device. When the protective rope sags, it needs to be manually tightened, which requires a certain amount of time and manpower, is not only time-consuming and labor-intensive, but may also affect the normal operation of the platform.

Both ends of the slide rod are fixed to the mounting body. A spring is fitted on the slide rod, and a tensioning block is slidably connected to the slide rod. The tensioning block has a rope winding part, which is configured to allow the protective rope to be bent and to tighten the protective rope. The tensioning block abuts against one end of the spring and is configured such that when the protective rope is tightened, the spring is compressed by the tensioning block. The rope end lock includes two, located on the upper and lower sides of the rope tension retainer, and is configured to lock and fix the two ends of the same protective rope, which is wound in an S-shape between the two lifting gate posts.

[0006] In the above scheme, the rope end lock is vertically aligned with the end of the slide bar closest to the other lifting gate post.

[0007] In the above scheme, the main body of the installation is a vertically arranged plate, the rope end lock and the rope tension retainer are located on the same side plate of the main body of the installation, and the slide rod is parallel to the plate surface of the main body of the installation.

[0018] like Figures 1 to 3 As shown, this utility model embodiment provides a platform safety rope 6 quick tensioning device for automatically maintaining the tension of the safety rope 6 connected between two lifting gate posts (not shown in the figure).

[0019] The rope safety gate installed on the platform includes multiple lifting gate posts distributed along the edge of the platform. A protective rope 6 is connected between two adjacent lifting gate posts for interception and protection. The protective rope 6 can be fixedly installed on the two lifting gate posts or driven by the lifting mechanism on the two lifting gate posts to move up and down. The rope safety gate of the platform is existing technology, so it will not be described in detail here. The following is a detailed description of the device of this application.

[0020] The device of this application is installed on one of the lifting gate posts, and includes a mounting body 1, a rope end locker 2, and a rope tension retainer 3.

[0021] Mounting body 1 is used to connect with the lifting gate post. In this embodiment, it is a vertically arranged plate. Rope end lock 2 and rope tension retainer 3 are located on the same side plate of mounting body 1. For ease of understanding and correspondence with the accompanying drawings, in this embodiment, it is defined that rope end lock 2 and rope tension retainer 3 are located on the front plate of mounting body 1.

[0022] The rope tension retainer 3 includes a slide rod 31, which extends horizontally along the placement direction of two adjacent lifting gate posts and is parallel to the surface of the mounting body 1. Both ends of the slide rod 31 are fixed to the mounting body 1, specifically connected to the left and right sides of the mounting body 1 via a first mounting member 12 and a second mounting member 13, respectively, with the first mounting member 12 closer to the other lifting gate post. A spring 32 is fitted onto the slide rod 31, and a tensioning block 33 is slidably connected to the slide rod 31. The tensioning block 33 is fitted onto the slide rod 31 via an oil-impregnated copper sleeve and can slide along the axial direction of the slide rod 31. The tensioning block 33 has a rope winding portion 34. The rope winding portion 34 is used for winding the protective rope 6 so that the protective rope 6 is tightened by the sliding of the tensioning block 33. One end of the tensioning block 33 abuts against the spring 32, and the other end of the spring 32 abuts against the first mounting member 12. In the initial tensioned state, the protective rope 6 is taut, and a force is applied to the tensioning block 33 through the rope winding part 34, causing it to compress the spring 32. At this time, the spring 32 is in a compressed state, storing elastic potential energy. If the tension of the protective rope 6 decreases and it sags, the tensioning block 33 moves away from the first mounting member 12 under the elastic force of the spring 32 to compensate for the elongation of the protective rope 6 and maintain the tension of the protective rope 6.

[0023] Two rope end lockers 2 are provided, located above and below the rope tension retainer 3 respectively, and vertically aligned with the end of the slide bar 31 near the other lifting gate post. These two rope end lockers 2 are used to lock and secure both ends of the same protective rope 6, which winds in an S-shape between the two lifting gate posts. Specifically, one end of the protective rope 6 is first fixed to one rope end locker 2, taking the upper rope end locker 2 as an example; then the protective rope 6 extends horizontally towards the opposite lifting gate post and passes downwards around its first fixed point, such as a pulley; then it returns horizontally to this device and passes downwards around the rope winding part 34; then it returns horizontally to the opposite lifting gate and passes downwards around the second fixed point; then it returns horizontally to this device, and the other end is locked by the lower rope end locker 2 of this device. This forms an S-shaped rope winding path.

[0024] The device of this application is used to lock a single protective rope 6, which forms a barrier area with a certain horizontal length and vertical width between two lifting gate posts through an S-shaped winding. A rope tension retainer 3 supports the middle section of the protective rope 6, thus tightening the entire rope 6. This design simplifies the structure of this application, thereby simplifying the installation steps of the protective rope 6, reducing installation difficulty, and allowing the device to be more compact, smaller in size, reducing space occupation, and lowering production and maintenance costs. Furthermore, using a single protective rope 6 and applying tension through a single rope tension retainer 3 ensures consistent tension across all sections of the rope 6, preventing uneven tension from causing partial slack or excessive tightness in multiple ropes 6. Moreover, when the single protective rope 6 is wound in an S-shape, the force is shared by the entire structure, resulting in a more reasonable force distribution compared to multiple ropes 6 each bearing their own force. This makes it less prone to damage due to excessive local stress during long-term use, and enhances overall stability.

[0025] like Figure 1 and Figure 3 As shown, in order to ensure the stability of the movement of the tension block 33 and the rope winding part 34, a limiting groove 11 is provided on the mounting body 1. The limiting groove 11 extends horizontally and its position corresponds to the space between the two rope end locks 2.

[0026] The rope winding section 34 is a cylindrical column, with its axis perpendicular to the slide bar 31. One end of the rope winding section 34 is fixedly connected to the tensioning block 33, and the other end extends toward the limiting slide groove 11, entering the limiting slide groove 11 and slidingly engaging with it. To reduce friction, a guide wheel 35 is provided on the end of the rope winding section 34 that extends into the limiting slide groove 11. The guide wheel 35 rolls within the limiting slide groove 11 and slides in cooperation with it.

[0027] The limiting groove 11 not only serves as a guide but also restricts the travel of the tensioning block 33. The limiting groove 11 is located on the side of the rope end lock 2 away from the other lifting gate post, and its end near the rope end lock 2 does not extend between the two rope end locks 2, thereby ensuring the structural strength of the installation position of the two rope end locks 2.

[0028] As a preferred dimensional relationship, the length of the limiting groove 11 is designed to be / to / of the length of the slide bar 31, which not only provides sufficient movement space for the tensioning block 33, but also avoids excessive movement of the tensioning block 33 that could damage the spring 32, and provides an adjustment reference for the initial tension of the protective rope 6.

[0029] like Figure 2As shown, the rope end locking device 2 includes a rope threading part 21 and a locking tooth 22. The rope threading part 21 has a rope receiving groove 211 for the protective rope 6 to pass through. The locking tooth 22 is connected to the rope threading part 21 by a screw 23. After the end of the protective rope 6 passes through the rope receiving groove 211, tightening the screw 23 causes the locking tooth 22 to press against the protective rope 6 from one side of the rope receiving groove 211, thereby securing the protective rope 6. See details... Figure 2 As shown, the rope groove 211 extends horizontally, with an inclined wall bent on one side. The locking tooth 22 is a wedge, its inclined surface abutting against the inclined wall and capable of sliding along it. The locking tooth 22 has a horizontally penetrating slot, and the inclined wall has a horizontally extending threaded hole. The screw 23 passes through the slot and connects to the threaded hole. When the screw 23 is tightened, it applies a compressive force to the locking tooth 22, causing it to move along the inclined wall and press against the protective rope 6 within the rope groove 211. Figure 2 As shown, the horizontal movement direction of the locking tooth 22 during the pressing action is opposite to the insertion direction of the rope end of the protective rope 6. This enables the rope end locker 2 to have a certain self-locking ability and improves the effect of the rope end locker 2 in locking and fixing the protective rope 6.

[0030] In addition, such as Figure 1 As shown, the first mounting member 12 extends horizontally and longitudinally, with symmetrically recessed rope grooves 121 on its upper and lower sides. The parallel ropes located on both sides of the rope winding portion 34 pass through the two rope grooves 121. In this way, while ensuring the supporting strength of the first mounting member 12, the distance between the two parallel ropes is reduced, allowing the two rope end locks 2 to be closer together, thereby improving the overall compactness of the device structure of this application.

[0031] To further enhance safety, the device in this application also includes a broken rope alarm 4. The broken rope alarm 4 is mounted on a rope end lock 2, located on the side of the rope end lock 2 closest to another lifting gate post. The broken rope alarm 4 has a micro switch. When the protective rope 6 is under normal tension, the protective rope 6 presses down on the micro switch, disconnecting the alarm circuit. Once the protective rope 6 breaks and loses tension, the pressure on the micro switch disappears, and the switch returns to a closed state, triggering an audible and visual alarm or sending a signal to the control center to promptly alert personnel. The broken rope alarm 4 can be any commercially available alarm with a micro switch.

[0032] To facilitate quick tightening of the protective rope 6 during initial installation or adjustment of the spring 32 tension during maintenance, the device of this application includes a one-way bearing 5. This one-way bearing 5 is mounted on the mounting body 1, located on the side of one rope end lock 2 away from the other lifting gate post. As per this application… Figure 1In this configuration, the one-way bearing 5 corresponds to the lower rope end lock 2 and is located to the left of the rope end lock 2. The end of the protective rope 6 passes through the lower rope end lock 2 without being locked initially; it is first wound or connected to the one-way bearing 5. Rotating the one-way bearing 5, utilizing its unidirectional rotation characteristic, tightens the protective rope 6, and then the end of the protective rope 6 is locked in place by the rope end lock 2. This provides the operator with a labor-saving and efficient method of applying preload. The one-way bearing 5 is a mature product already existing in the art, and its structure will not be described in detail here. Those skilled in the art can select a commercially available one-way bearing of a suitable model according to its dimensions.
