It provides a stable connection point for the safety rope, allowing the safety rope on the construction workers to be reliably suspended when working at height to prevent people from falling.

[0003] In the prior art, some suspension devices are usually fixed to the utility poles using bolts and nuts. Since the use of bolts and nuts is time-consuming and troublesome during the installation and removal process, the complex operation of bolts and nuts at high altitudes for a long time will cause the workers to be exposed to the high-altitude environment for a longer time, increasing the risk of falling, fatigue, etc. Therefore, a safety rope suspension device for power transmission and transformation projects is proposed to solve the above problems. Summary of the Invention

[0004] In order to make up for the above shortcomings, the utility model provides a safety rope suspension device for power transmission and transformation projects, aiming to improve the problem that some suspension devices in the prior art are time-consuming and troublesome during the disassembly and installation process.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figures 1 to 3 The utility model provides an embodiment of a safety rope hanging device for power transmission and transformation projects, including a shell 1, which serves as the main structure of the entire device and provides installation and protection space for various internal components. The internal bolts of the shell 1 are connected with a threaded column 2. When the handle 4 is turned to drive the connecting column 3 and thus the threaded column 2 is rotated, the axial movement of the threaded column 2 can push the rotating rod 7 to move. The external rear end of the threaded column 2 is fixedly connected with the connecting column 3. The external part of the connecting column 3 is fixedly connected with a handle 4 for the operator to hold and rotate to control the movement of the threaded column 2. The front end of the shell 1 is fixedly connected with a protrusion 5. When the threaded column 2 moves, the protrusion 5 contacts the adjacent side of the rotating rod 7, limiting the movement range of the rotating rod 7 and ensuring that the rotating rod 7 rotates within a certain angle, thereby ensuring that the movement trajectory of the clamping plate 13 is stable.

[0032] The outside of the protrusion 5 is rotatably connected to the inside of the shell 1, and the inside of the shell 1 is fixedly connected to two support rods 6 to provide rotation support for the rotating rod 7. The position and angle of the support rod 6 are carefully designed so that the rotating rod 7 can rotate within the appropriate position and angle range, thereby realizing the accurate opening and closing action of the clamping plate 13. The inside of the shell 1 is rotatably connected to the two rotating rods 7, and the internal rotation of the rotating rod 7 is connected to the outside of the support rod 6. The outside of the protrusion 5 contacts the adjacent side of the two rotating rods 7. The left and right ends of the inside of the shell 1 are fixedly connected with elastic components for reset. The elastic component includes two telescopic rods 8, one end of the telescopic rod 8 is fixedly connected to the inside of the shell 1, and the outer rear ends of the two telescopic rods 8 are fixedly connected to the inner top of the shell 1. The outside of the two telescopic rods 8 is fixedly connected with a spring 9. When the rotating rod 7 squeezes the limit block 10 to shrink the telescopic rod 8, the spring 9 is compressed to store elastic potential energy. When the clamping needs to be released, the elastic potential energy of the spring 9 is released, pushing the limit block 10, thereby driving the rotating rod 7 to rotate in the opposite direction to release the clamping plate 13.

[0033] The adjacent sides of the two telescopic rods 8 are fixedly connected to the limit block 10, the outside of the limit block 10 is slidably connected to the inside of the shell 1, the outside of the limit block 10 is in contact with the rotating rod 7, the other end of the telescopic rod 8 is fixedly connected to the rear end of the limit block 10, both sides of the rear end of the shell 1 are fixedly connected to the fixed frame 11, the inside of the shell 1 is slidably connected to the sliding block 12, the front end of the rotating rod 7 is fixedly connected to the rear end of the sliding block 12, the adjacent sides of the two sliding blocks 12 are fixedly connected to the clamping plate 13, the inside of the clamping plate 13 is fixedly connected to the friction block 14, which increases the friction between the clamping plate 13 and the clamped object.

[0034] Reference Figure 2 、 Figure 4 The bottom end of the shell 1 is fixedly connected to a rotating shaft 15, and the outer left end of the rotating shaft 15 is fixedly connected to a ratchet 16. The ratchet 16 is rotatably connected to the inner bottom end of the shell 1. The inner left end of the shell 1 is fixedly connected to a fixed rod 17, and the outer side of the fixed rod 17 is rotatably connected to a pawl 18. When the safety rope suddenly falls, the ratchet 16 rotates rapidly, and the pawl 18 engages with the ratchet 16 under the action of the ball 20, preventing the ratchet 16 from rotating and achieving quick locking. The outer side of the ratchet 16 is meshed with the outer side of the pawl 18. A sliding groove 19 is provided at the inner left end of the shell 1. The inner side of the sliding groove 19 is slidably connected to the ball 20, and the outer side of the ball 20 contacts the outer side of the pawl 18.

[0035] Working Principle: First, the operator grasps handle 4 and rotates threaded post 2 via connecting post 3. Because threaded post 2 is bolted to the interior of housing 1, its rotation generates axial displacement. As threaded post 2 moves, connecting post 3 at its rear end also moves, driving handle 4 in motion. Simultaneously, a bump 5 at the front end of housing 1 provides support and positioning within the housing. Movement of threaded post 2 does not affect the position of bump 5.

[0036] Inside the housing 1, support rod 6 provides rotational support for rotating rod 7. When threaded post 2 moves, it pushes rotating rod 7, which is in contact with it, to rotate around support rod 6. The front end of rotating rod 7 is fixedly connected to sliding block 12, so rotation of rotating rod 7 causes sliding block 12 to slide within the housing 1. Clamping plate 13 on the side adjacent to sliding block 12 also moves accordingly. Friction block 14 within clamping plate 13 increases friction with the clamped object, ensuring stable grip.

[0037] Furthermore, the elastic component within the housing 1 plays a crucial role in this process. When the threaded post 2 pushes the rotating rod 7, it compresses the contacting stopper 10. This compresses the telescopic rod 8 connected to the rear end of the stopper 10, and the external spring 9, too, stores elastic potential energy. When the clamping action needs to be released, the elastic potential energy of the spring 9 is released, pushing the stopper 10, which in turn drives the rotating rod 7 in the opposite direction, releasing the clamping plate 13.

[0038] At the bottom of the safety rope suspension device, when the safety rope suddenly drops, ratchet 16 on the outer left end of rotating shaft 15 rotates rapidly. A pawl 18, rotatably connected to fixed rod 17 on the left end of housing 1, engages with ratchet 16, preventing reverse rotation and achieving a quick lock. Simultaneously, a ball 20 in a sliding groove 19 contacts the outer surface of pawl 18, reducing friction between pawl 18 and other components and ensuring smoother movement.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
