Description

Technical Field

[0001] This utility model relates to the technical field of safety devices for high-altitude operations, and in particular to a quick-installation anti-disengagement safety rope connection device for high-altitude operations. Background Technology

[0002] In high-altitude operations, safety ropes are typically worn and connected to reliable anchor points to ensure worker safety. However, existing methods for connecting safety ropes are often inconvenient, inefficient, and prone to accidental detachment of the hook during operation, posing a significant safety hazard to workers. Traditional connection methods usually require manual connection and disconnection, which is not only time-consuming and laborious in high-altitude environments but also more difficult and prone to misoperation in inclement weather or poor lighting conditions. Therefore, developing a high-altitude safety rope connection device that enables rapid connection, is easy to operate, and effectively prevents detachment is crucial for improving the efficiency and safety of high-altitude operations. Utility Model Content

[0003] To address the problems of inconvenient operation, low connection efficiency, and risk of decoupling in existing high-altitude work safety rope connection devices, a quick-installation anti-decoupling safety rope connection device is provided, which is simple in structure, easy to operate, and can achieve rapid connection of safety ropes and reliable anti-decoupling.

[0004] The technical solution adopted by this utility model is: a quick-installation anti-disengagement safety rope connection device for high-altitude operations, including an outer rod, an inner rod, and a connecting rope. The inner rod is slidably sleeved inside the outer rod. The bottom end of the outer rod is provided with a lifting ring for fixing the safety rope. The top end of the inner rod is fixedly connected to a fixing plate, and the fixing plate is provided with a hook assembly. The hook assembly includes: a fixing part, the top of which is rotatably connected to a pulley; a rotating part, the bottom end of which is rotatably connected to the fixing plate, and the top end of which extends to a connecting block; the outer rod is provided with a positioning block with a through hole; one end of the connecting rope is fixed to the connecting block, and the other end passes around the pulley, passes through the through hole, and extends to the outside of the outer rod. A torsion spring is provided at the pivot of the rotating part 42.

[0005] Preferably, the inner rod is provided with a plurality of adjustment holes, and the top end of the outer rod is provided with a corresponding mounting hole, and the bolt passes through the mounting hole and the selected adjustment hole.

[0006] Preferably, a reel is rotatably connected to the bottom end of the outer rod, and one end of the connecting rope extending to the outside of the outer rod is fixed inside the reel.

[0007] Preferably, the inner rod has guide blocks on both sides, the outer rod has a corresponding sliding groove on the top of its inner wall, and the inner rod has a limiting block at its bottom.

[0008] Preferably, a knob is coaxially fixed to the outside of the reel.

[0009] Preferably, the end of the fixing part is provided with an inclined surface facing the inside of the hook assembly, and the end of the rotating part is provided with an inclined surface facing the outside of the hook assembly.

[0010] Preferably, the connecting block, pulley, positioning block, and reel are all located on the same radial side of the outer rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are: The sliding sleeve structure of the inner and outer rods allows for the extension and retraction adjustment of the device's length. Combined with adjustment holes, mounting holes, and bolts, it can be quickly fixed according to the requirements of different working heights, thus improving the adaptability of the device.

[0012] 2. The hook assembly opens and closes by pulling the connecting rope. The beveled design at the ends of the fixed and rotating parts ensures that the hook automatically closes or remains closed when the connecting rope is not pulled by external force, effectively preventing accidental detachment and significantly improving safety during high-altitude operations. The connecting rope extends to the outside of the outer pole and is wound up and down via a reel. Combined with knob operation, this allows operators to control the opening, closing, and connection of the hook without direct contact with it during high-altitude work. They can simply operate the reel at the bottom of the outer pole to control the hook's opening, closing, and connection, greatly simplifying operation and improving work efficiency.

Detailed Implementation

[0015] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0016] like Figures 1-4 As shown, this utility model provides a quick-installation anti-disengagement safety rope connection device for high-altitude operations, including an outer rod 1, an inner rod 2, and a connecting rope 3.

[0017] The inner rod 2 is slidably sleeved inside the outer rod 1, allowing the entire device to be length-adjustable like a telescopic rod. At the bottom end of the outer rod 1, there is a lifting ring 11 for fixing the safety rope, and the worker's safety rope can be connected to this lifting ring 11.

[0018] A fixing plate 21 is fixedly connected to the top of the inner rod 2, and a hook assembly 4 is provided on the fixing plate 21. The hook assembly 4 includes a fixing part 41 and a rotating part 42. A pulley 43 is rotatably connected to the top of the fixing part 41. The bottom end of the rotating part 42 is rotatably connected to the fixing plate 21, and a connecting block 44 extends from its top end.

[0019] A positioning block 5 is provided on the side wall of the outer rod 1, and the positioning block 5 has a through hole 51.

[0020] One end of the connecting rope 3 is fixed to the connecting block 44 of the hook assembly 4, and the other end passes through the pulley 43, through the through hole 51 on the positioning block 5, and finally extends to the outside of the outer rod 1. When the operator pulls the connecting rope 3 that extends to the outside, the rotating part 42 will rotate around its rotation axis through the linkage of the pulley 43 and the connecting block 44, causing the hook assembly 4 to open; when the connecting rope 3 is released, the rotating part 42 returns to its original position under the action of the torsion spring, causing the hook assembly 4 to close, thereby realizing the quick attachment and anti-disengagement function of the safety rope.

[0021] To achieve precise adjustment and fixation of the device length, the inner rod 2 is provided with several adjustment holes 22 along its length direction, and the top of the outer rod 1 is provided with a corresponding mounting hole 12. When the inner rod 2 extends or retracts to the required length, the operator can insert bolts 6 into the mounting holes 12 of the outer rod 1 and the selected adjustment holes 22 of the inner rod 2, thereby locking the inner rod 2 and the outer rod 1 at a fixed length and ensuring stability during use.

[0022] To facilitate the winding and management of the connecting rope 3, a reel 7 is rotatably connected to the bottom end of the outer rod 1. One end of the connecting rope 3 extending to the outside of the outer rod 1 is fixed inside the reel 7. A knob 71 is coaxially fixed to the outside of the reel 7, allowing operators to manually rotate the knob 71 to wind up or wind up the connecting rope 3, keeping it clean and preventing tangling.

[0023] To ensure smooth and stable sliding of the inner rod 2, guide blocks 23 are provided on both side walls of the inner rod 2. These guide blocks 23 cooperate with the corresponding sliding grooves provided on the top of the inner wall of the outer rod 1, providing guidance during the extension and retraction of the inner rod 2 and reducing swaying. At the same time, a limiting block 24 is provided at the bottom end of the inner rod 2 to prevent the inner rod 2 from completely detaching from the outer rod 1 when it overextends, thereby improving the safety of the device.

[0024] To further optimize the opening and closing mechanism and anti-disengagement effect of the hook assembly 4, the end of the fixing part 41 is provided with an inclined surface facing inward towards the hook assembly 4, and the end of the rotating part 42 is provided with an inclined surface facing outward towards the hook assembly 4. This inclined surface design helps the rotating part 42 to rotate more smoothly when the connecting rope 3 is pulled, making it easier to open the hook; and when the connecting rope 3 is released, the interaction between the inclined surfaces of the rotating part 42 and the fixing part 41 enables a more reliable self-closing or maintaining a closed state, effectively preventing accidental disengagement.

[0025] To make the device structure more compact and ensure the optimal running path of the connecting rope 3, the connecting block 44, pulley 43, positioning block 5, and reel 7 are all located on the same radial side of the outer rod 1. This layout makes the wiring of the connecting rope 3 inside the device more direct, reduces the possibility of friction and tangling, and also makes the overall shape of the device more regular.

[0026] Working principle: Based on the actual height requirements of the high-altitude operation, extend the inner rod 2 from the outer rod 1 to a suitable length, and then fix it by passing the bolt 6 through the mounting hole 12 and the selected adjustment hole 22. Next, the operator can bring the hook assembly 4 at the top of the device close to the fixing point to be connected. At this time, by pulling the connecting rope 3 extending from the bottom of the outer rod 1, the rotating part 42 of the hook assembly 4 will rotate, causing the hook to open. After hooking the opened hook assembly 4 into the fixing point, release the connecting rope 3. The hook assembly 4 will automatically close under the action of the torsion spring, firmly hooking the fixing point, completing the connection of the safety rope. Because the hook assembly 4 has an anti-disengagement design, it is difficult to accidentally disengage even if it is subjected to external impact during the operation. When the operation is over and the connection needs to be removed, simply pull the connecting rope 3 again to open the hook, and the device can be removed from the fixing point. Finally, retract the connecting rope 3 by turning the knob 71 on the reel 7, and retract the inner rod 2 into the outer rod 1.
