[0002] High-voltage transmission line maintenance often requires climbing towers to high altitudes, making the protection of personnel particularly important. Personnel working at height typically have at least two sets of safety ropes with safety hooks, each attached to a secure structure. Due to the structure of most existing towers, which lack anti-fall rails, personnel are generally unprotected during ascent and descent. Climbing requires alternating the safety hooks of the safety ropes, which are fastened to tower components.

[0003] The prior art has the following technical problems: 1. The safety hook of the traditional protection rope has a fixed and small opening. Due to design limitations, the size of the hook cannot be increased blindly, as this will increase the weight and make it very difficult for people to hold it.

[0004] 2. It is not possible to hang on the main material of the tower that is closest to the climber's body and has the highest strength. The climber needs to constantly look for suitable auxiliary materials around for hanging, which greatly affects work efficiency and makes the process of going up and down the tower extremely slow. Summary of the Invention

[0023] The purpose of the present invention is to propose a special safety hook for high-altitude climbing of iron towers, aiming to solve the technical problem of the disadvantage of limited use range of existing safety protection devices. The present invention uses a connecting piece as a hinge to control the opening and closing of the safety hook, and has a safety limit device, which can adapt to iron tower materials of any size and can be effectively hung. High-altitude personnel can hang and remove the safety hook nearby, and at the same time reduce the time for high-altitude personnel to find suitable auxiliary materials for hanging, reduce work intensity, and improve work efficiency.

[0024] Example like Figure 1-5As shown, a safety hook for high-altitude climbing on iron towers is assembled from a safety 1, a double-support spring 2, a movable handle 3, a connecting piece 4, a connecting shaft 5, a main hook 6, a main handle 7, a safety washer 8, a small cylinder 9, and bolts and nuts. The movable handle 3 and two main hooks 6 are movably connected to the main handle 7.

[0025] like Figure 6-7 As shown, the main handle 7 includes an upper plate 10 and a bottom plate 11 connected by an intermediate connecting plate. Vertical poles 12 are fixedly provided at both ends of the bottom plate 11, and the vertical poles 12 are provided with stepped serrations 13 on the outer side.

[0026] like Figure 9-11 As shown, the movable handle 3 includes an upper layer 14 and a lower layer 15 connected by an intermediate connecting piece corresponding to the positions of the upper plate 10 and the bottom plate 11, and the two ends of the lower layer 15 are respectively fixed with limiting grooves 16 corresponding to the positions of the vertical poles 12. The vertical poles 12 can pass through the limiting grooves 16, and the two limiting grooves 16 can be displaced up and down on the two vertical poles 12.

[0027] like Figure 13 As shown, the front end of the main hook 6 is provided with a curved hook for hanging objects, and the rear end is provided with a through hole for installation on the main handle 7. The middle positions of the upper plate 10 and the bottom plate 11 of the main handle 7 are respectively provided with corresponding through holes for fixing the rear ends of the two main hooks 6 by bolts and nuts.

[0028] Furthermore, a through hole is provided near the rear end through hole of the main hook 6, for the connecting shaft 5 to pass through and be plugged into the through hole at one end of the connecting piece 4. Figure 14 The other end of the connecting piece 4 is provided with a through-hole for mounting the connecting piece 4 on the movable handle 3. Corresponding through-holes are provided between the upper layer 14 and the lower layer 15 of the movable handle 3 for securing the other ends of the two connecting pieces 4 with bolts and nuts. This indirectly connects the two main hooks 6 to the movable handle 3, with the two main hooks 6 passing through the space between the upper layer 14 and the lower layer 15, respectively, and located on the left and right sides of the connector.

[0029] like Figure 15 As shown, one end of the connecting shaft 5 is provided with a through hole, and a through hole as shown in FIG. Figure 16 The double-support spring 2 shown is used to keep the two main hooks 6 in a closed state. The double-support spring 2 pulls the through holes of the two connecting shafts, drives the connecting piece to rotate, and prompts the two main hooks to close.

[0030] The above connecting piece is used as a hinge to control the opening and closing of the two main hooks, and the double support spring 2 allows the opening of the safety hook to be adjusted arbitrarily. It can not only be easily locked and hooked to the auxiliary materials of any iron tower, but also adapt to the main material size of most iron towers, and can completely hook the main tower material with the highest strength.

[0031] Furthermore, a safety groove 17 is provided between the lower layer 15 of the movable handle 3 and the intermediate connecting piece for clamping the safety 1 .

[0032] like Figure 12 As shown, the safety 1 includes a clip 18 and two paddles 19 fixedly connected to the clip 18. The clip 18 is clipped into the safety slot 17 and can slide left and right within the safety slot 17. A protrusion 20 is fixedly provided at each end of the clip 18, which is used to engage the stepped serrations 13 on the vertical rod 12 when the protrusion 20 slides into the limiting slot 16. The two protrusions 20 on the safety 1 are positioned exactly to engage the stepped serrations 13 on the two vertical rods 12.

[0033] Furthermore, a wall of the vertical rod 12 is provided on one side of the stepped serrations 13 to limit the sliding position of the clamping bar 18. The clamping bar 18 can be moved in and out from the other side, thereby allowing the two protrusions 20 on the safety 1 to engage / relax the stepped serrations 13 on the two vertical rods 12, flexibly controlling the distance between the movable handle and the main handle.

[0034] like Figure 8 As shown, after the clamping strip 18 is clamped in the safety slot 17, the position of the movable handle 3 and the safety 1 is clamped by the safety gasket 8, and they are fixed and installed by bolts and nuts.

[0035] Furthermore, a small cylinder 9 is provided on the paddle 19 and at a horizontal position corresponding to the safety gasket 8, respectively. A through hole is provided on the small cylinder 9, and a double-support spring 2 is hung on the through holes of the two small cylinders 9, for keeping the two protrusions 20 in a position to clamp the two stepped serrations 13. The function of the double-support spring 2 is to reset the safety in time to prevent personnel from operating it incorrectly and avoid unhooking and loss of protection.

[0036] Furthermore, a through hole is provided at the front end of the main hook 6 near the position of the hook for movably connecting a set of bolts and nuts. The set of bolts and nuts is used to hold the angle iron in place when hooking the iron tower so that it is not tilted by gravity.

[0037] There is also a rope loop on the main handle for hanging a rope.

[0038] The through holes can also be designed as threaded holes to facilitate the fixing of bolts and nuts.

[0039] Working principle: like Figure 17-19 As shown, after the safety hook for high-altitude tower climbing is assembled, the two main hooks are locked due to the tension of the double-bracing springs, and the safety is also locked. To use, first release the safety. Then, use your finger to slide the safety lever out of the safety slot until it no longer blocks the stop slot for the movable handle. This releases the stepped serrations on the vertical pole. Applying pressure allows the movable handle to move closer relative to the main handle, and the two connecting plates drive the two main hooks to open to the desired position. Once the safety hook is opened, the curved hook at the front of the main hook engages the main member of the tower. Release the grip and no longer apply pressure. The safety hook automatically returns to its original position due to the tension of the double-bracing springs, locking the movable handle relative to the main handle. Simultaneously, the main hook is locked and cannot open, securing the safety hook to the tower. The two sets of bolts and nuts at the front of the main hook prevent the safety hook from tilting. By supporting the main member of the tower, it prevents movement and facilitates manual grip. This cycle of use provides safe access for climbing and descending the tower.

[0040] The special safety hook for high-altitude tower climbing provided by the present invention uses a connecting piece as a hinge to control the opening and closing of the safety hook. It also has a safety limiter device, which can adapt to tower materials of any size and can effectively hook them securely. Workers at high altitudes can easily hang and remove the safety hook nearby, improving work efficiency.
