Abstract
Description
Technical Field
[0001] This utility model relates to the field of high-altitude protection technology, and in particular to a sliding limit structure for a high-altitude safety rope. Background Technology
[0002] A safety rope is a crucial piece of equipment used to ensure the safety of personnel during high-altitude operations. It is typically made of high-strength fiber or metal materials woven or twisted together. One end is connected to the worker's safety harness, and the other end is secured to a reliable anchor point at a high location, such as a stable building structure or equipment frame. During high-altitude operations, if a worker accidentally falls, the safety rope can support the worker's weight, preventing further fall and playing a vital role in suspending and protecting the worker's life. Its length, strength, and other parameters are designed according to the specific working environment and safety standards.
[0003] The slip-limiting structure of a high-altitude safety rope is a key component of the high-altitude work safety protection system. It ensures the safety rope's safety while reasonably limiting its slippage. It clamps the safety rope in case of abnormal slippage, preventing further sliding. This prevents workers from exceeding the designated safe activity area, thus protecting the personal safety of high-altitude workers from multiple perspectives.
[0004] Existing high-altitude safety rope sliding limit structures cannot provide movement assistance during the user's climbing process, which wastes the user's physical strength and affects the quality and efficiency of subsequent high-altitude operations. Therefore, a high-altitude safety rope sliding limit structure is proposed to solve the above problems. Utility Model Content

A drive plate 7 is fixedly connected to the drive end of the adjusting cylinder 6. The drive plate 7 can drive the subsequent components to move under the drive of the adjusting cylinder 6.
[0035] A rotating wheel 8 is rotatably connected to the front end of the drive plate 7. The rotating wheel 8 can cooperate with the rotating wheel 4 to drive the entire device to move.

[0036] Reference Figure 1 and Figure 3 The braking assembly includes a dual-cylinder 9, which provides sufficient and stable power output for the movement of subsequent components. Each drive end of the dual-cylinder 9 is fixedly connected to a motion frame 10, which drives the subsequent components under the influence of the dual-cylinder 9. A pressure plate 11 is fixedly connected to a nearby end of each of the two motion frames 10. The pressure plate 11 causes the safety rope to deform under the influence of the motion frames 10, preventing the user from falling. A limiting shaft 12 is slidably connected inside the motion frame 10, providing limitation and guidance for the movement of the motion frame 10.
[0037] Reference Figures 2 to 4 The limiting assembly includes a fixed shaft 13, which provides a limit for the rotation of subsequent components. A fixed block 14 is externally fixed to the fixed shaft 13, and the fixed block 14 cooperates with the subsequent components to clamp the safety rope. The rear end of the fixed shaft 13 is fixedly connected to the front end of a fixed plate 1, which provides stable support for the fixed shaft 13. A fixed shaft 15 is fixedly connected to the front end of the fixed plate 1, which provides support for the rotation of related components. A rotating block 16 is rotatably connected to the outside of the fixed shaft 15, and the rotating block 16 can rotate to a suitable position to cooperate with the fixed block 14 to clamp the safety rope. A limiting block 17 is rotatably connected to the front end of the fixed plate 1, and the limiting block 17 can limit the rotation block 16 by rotating to a suitable position.
[0038] A rotating plate 18 is externally rotatably connected to the fixed shaft 15.

The front ends of the two limiting shafts 12 are slidably connected to the rear ends of the fixed plate 1, allowing the fixed plate 1 to cooperate with the limiting shafts 12 to improve the limiting effect.
[0039] The front end of the double-headed cylinder 9 is fixedly connected to the rear end of the fixed plate 1.

A groove is provided at the bottom end of the rotating plate 18, and the groove's structure is coupled to the fixed shaft 13, allowing it to slide smoothly outside the fixed shaft 13.
[0040] Working principle: Before the user needs to use the safety rope, the safety rope is placed between the rotating block 16 and the fixed block 14. The rotating block 16 is rotated so that the rotating block 16 and the fixed block 14 can clamp the safety rope. Then the limiting block 17 is rotated to fix the position of the rotating block 16. At this time, the rotating plate 18 is rotated until the groove at the bottom of the rotating plate 18 is slidably connected to the outside of the fixed shaft 13, thus completing the installation of the limiting component.
[0041] Place the safety rope between spool 4 and spool 8. Then, activate the adjusting cylinder 6. The adjusting cylinder 6 drives the drive plate 7 to move to the right inside the limit frame 5. The drive plate 7 drives spool 8 to move until it can cooperate with spool 4 to clamp the safety rope. Activate the motor 3. The motor 3 drives spool 4 to rotate on the surface of the safety rope. The friction force drives the entire device to move. The device moves in the same direction as the user's climbing direction, which can save the user's physical strength.
[0042] When the user falls, the fixed plate 1 drives the fixed block 14 and the rotating block 16 to bend the safety rope and prevent the fall. When the user is in an inconvenient position and cannot trigger the limit component, the double-headed cylinder 9 is activated. The double-headed cylinder 9 drives the two moving frames 10 to move towards one end. At the same time, the two moving frames 10 drive the two pressure plates 11 to move towards one end. The two pressure plates 11 squeeze and bend the safety rope to achieve braking.
[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
