Description

Technical Field

[0001] This utility model relates to the field of high-altitude operation protection technology, and in particular to a safety rope hook for high-altitude power operations. Background Technology

[0002] Safety rope hooks are personal protective equipment designed specifically for high-altitude operations. They use a mechanical structure to connect the safety rope to a fixed anchor point (such as a crossarm of a steel tower or a structural component of a building), ensuring the personal safety of workers in high-altitude scenarios such as power maintenance and protecting their lives.

[0003] In existing power line high-altitude work safety rope hooks, when workers are working at heights on power towers, they typically use the tower crossarm as the anchor point for the safety rope hook. Because the crossarm is set horizontally, the hook's position cannot be locked, causing the safety rope hook to slip due to the lack of limiting on both sides. During the slippage, the safety rope may become entangled in the crossarm angle steel, bolts, or adjacent conductors, trapping the worker in the air and increasing the risk of accidents. Furthermore, workers may be distracted by external factors, become inattentive, and forget operating procedures, lowering themselves before the hook is fully locked. Since the hook usually lacks an alarm mechanism, it may detach during descent, leading to a serious safety accident. Utility Model Content

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0029] Example 1:

[0030] Reference Figures 1-5 This is the first embodiment of the present utility model. This embodiment provides a safety rope hook for high-altitude power operations. The safety rope hook for high-altitude power operations includes a connecting block 1, and a shell 2 is fixedly connected to the outside of the connecting block 1.

[0031] One end of the connecting block 1 is provided with a main body component 3, the outer side of the main body component 3 is provided with a locking component 4, the outer side of the locking component 4 is provided with a locking component 5, the other end of the connecting block 1 is provided with a connecting component 8 for connecting a safety rope, and the outer side of the main body component 3 is provided with a sensor 6 and an alarm 7.

[0032] When sensor 6 is set up, after one end of locking block 52 touches the mechanical contact of sensor 6, sensor 6 will transmit an electrical signal to the control unit of alarm 7. When alarm 7 is set up, alarm 7 is powered by battery. When the hook is not fully locked, alarm 7 will emit flashing light and sound to remind staff to prevent negligence. This is existing technology and will not be described in detail here.

[0033] The inner shell 2 is symmetrically provided with two sets of moving components 9 and guide components 11. The outer sides of the two sets of moving components 9 are provided with springs 10 and support components 12. The outer side of the support components 12 is provided with a positioning frame 13 to prevent excessive displacement of the hook. The top of the positioning frame 13 is fixedly connected with an anti-slip pad 14 to increase friction. The outer side of the shell 2 is provided with an adjustment component 15. The outer side of the adjustment component 15 is provided with a fixing component 16.

[0034] By setting a spring 10, after deformation, the spring 10 will push the moving component 9 to move through elastic restoring force; by setting a positioning frame 13, which is designed according to the shape of the iron tower crossarm that serves as the hook anchor point when workers are working on the power tower, the positioning frame 13 is fixed to the outside of the iron tower crossarm to prevent the hook from sliding excessively; by setting an anti-slip pad 14, which is made of rubber, the friction between the positioning frame 13 and the contact surface of the iron tower crossarm is increased.

[0035] Example 2:

[0036] Reference Figures 1-3 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0037] Specifically, the main component 3 includes a fixing seat 31 fixed to one end of the connecting block 1, a connecting shaft 32 is provided at the top of the fixing seat 31, a rotating ring 33 is rotatably connected to the outside of the connecting shaft 32, an alarm 7 is installed on the outside of the rotating ring 33, and a sensor 6 is installed at the top of the fixing seat 31.

[0038] The rotating ring 33 rotates around the connecting shaft 32 to open and close the hook.

[0039] Specifically, the locking assembly 4 includes a first locking block 41 fixed to one end of the rotating ring 33, and a second locking block 42 fixedly connected to the top of the fixing seat 31.

[0040] One end of the first card block 41 and the second card block 42 are semi-circular and fit together.

[0041] Specifically, the locking component 5 includes a threaded groove 51 located on the outside of the first locking block 41 and the second locking block 42, and a locking block 52 is threadedly connected to the inner wall of the threaded groove 51.

[0042] When the locking block 52 rotates, it can move vertically along the threaded groove 51. When it moves to the connection between the first locking block 41 and the second locking block 42, it can close and lock the hook.

[0043] Specifically, the connecting component 8 includes a support base 81 fixed to one end of the connecting block 1, and a rope hole 82 is fixedly connected to the bottom of the support base 81.

[0044] The support base 81 is triangular. When the rope hole 82 is under tension, the support base 81 will transfer the concentrated load to the connecting block 1 and the outer shell 2 through the hypotenuse of the triangle, reducing local stress concentration and preventing material fatigue failure. The safety rope can pass through the rope hole 82 and be connected to the hook.

[0045] Example 3:

[0046] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0047] Specifically, the movable component 9 includes a guide rod 91 fixed to the inner wall of the housing 2, two sets of movable seats 92 slidably connected to the outer side of the guide rod 91, and a spring 10 sleeved on the outer side of the guide rod 91.

[0048] The guide rod 91 restricts the movement path of the movable seat 92, and the spring 10 supports one side of the movable seat 92. When the spring 10 releases its elastic force, it will push the movable seat 92 toward the middle point of the guide rod 91.

[0049] Specifically, the guide assembly 11 includes a guide block 111 fixed to the bottom of the movable seat 92, a guide rail 112 fixedly connected to the inner wall of the housing 2, and the outer side of the guide block 111 slidably connected to the inner wall of the guide rail 112.

[0050] When the movable seat 92 moves, it will cause the guide block 111 to slide along the inner side of the guide rail 112. The guide rail 112 restricts the movement path of the guide block 111 and ensures that the movable seat 92 moves according to the predetermined trajectory.

[0051] Specifically, the support assembly 12 includes a support rod 121 that rotates on the top of the movable seat 92, and a connecting seat 122 that is rotatably connected to the other end of the support rod 121. The top of the connecting seat 122 is fixedly connected to the bottom of the positioning frame 13.

[0052] As the height of the connecting seat 122 changes, one end of the support rod 121 will rotate along the inner side of the connecting seat 122. As the rotation angle of the support rod 121 changes, the other end of the support rod 121 will slide along the movable seat 92 toward one end of the guide rod 91.

[0053] Specifically, the adjustment assembly 15 includes an adjustment block 151 fixed to the outside of the connecting seat 122, and a slide groove 152 is provided on one side of the housing 2. The outer side of the adjustment block 151 is slidably connected to the inner wall of the slide groove 152.

[0054] When it is necessary to loosen the hook, the adjusting block 151 can be pulled downwards to lower the height of the connecting seat 122 and the positioning bracket 13.

[0055] Specifically, the fixing component 16 includes a screw 161 that slides on the inner wall of the adjusting block 151, a fixing claw 162 that is fixedly connected to one end of the screw 161, and a rotating wheel 163 that is threadedly connected to the outer side of the screw 161.

[0056] The inner wall of the adjusting block 151 has a through hole, and the screw 161 can slide inside the through hole. When the rotating wheel 163 is attached to one side of the adjusting block 151, as the rotating wheel 163 is gradually tightened, the rotating wheel 163 and the fixing claw 162 form a clamping force, which can interact to lock the adjusting block 151 to the inner wall of the outer shell 2, so that the position of the adjusting block 151 is fixed.

[0057] When in use, upon arrival at the work site, first rotate the rotating ring 33 around the connecting shaft 32, securing it to the outside of the tower crossarm. Then, close the rotating ring 33 with the fixed base 31, engaging the first locking block 41 and the second locking block 42. Next, rotate the locking block 52 to move downwards along the threaded groove 51. When it reaches the connection between the first locking block 41 and the second locking block 42, one end of the locking block 52 will touch the mechanical contact of the sensor 6. The sensor 6 then transmits an electrical signal to the control unit of the alarm 7, which then shuts off the flashing lights and sound alert. Through this mechanism, the sensor 6 and the alarm 7 achieve real-time monitoring and feedback of the hook locking status, ensuring that workers can only begin working at height after the safety device is correctly closed, significantly improving operational safety. The hook position needs to be monitored. During fixing, first rotate the wheel 163 to move it parallel to the axis of the screw 161, gradually moving it away from the surface of the adjusting block 151, causing the adjusting block 151 to lose its limit. At the same time, the connecting seat 122 is released from the fixed state. Subsequently, the spring 10 releases its elastic force, pushing the two moving seats 92 toward the center point of the guide rod 91. At the same time, the support rod 121 moves accordingly. As the position of the support rod 121 changes, it pushes the connecting seat 122 upward through its other end, causing the positioning frame 13 to be pressed against the outside of the iron tower crossarm. Then, rotate the wheel 163. When the wheel 163 is pressed against one side of the adjusting block 151, as the wheel 163 gradually tightens, the wheel 163 and the fixing claw 162 form a clamping force, which can interact to lock the inner wall of the outer shell 2, thus fixing the position of the adjusting block 151. This completes the fixing of the hook position.

[0058] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
