[0021] Example one

[0022] As shown in Figure 1 , 2 , a fall-preventing climbing tower auxiliary tool includes a hooking frame 1, a sealing rod 2, a sliding rail rod 3, a connecting rod 4 and a handle rod 5. The hooking frame 1 is a frame structure with an open lower end. The sealing rod 2 is rotatably connected to the left side of the open lower end of the hooking frame 1. The sliding rail rod 3 is vertically arranged, and the upper end of the sliding rail rod 3 is connected to the left side of the lower end of the hooking frame 1. The handle rod 5 is vertically arranged, and the handle rod 5 is slidably matched with the sliding rail rod 3. The upper end of the connecting rod 4 is connected to the middle part of the sealing rod 2, and the lower end of the connecting rod 4 is connected to the upper part of the handle rod 5. A limiting structure is arranged between the handle rod 5 and the sliding rail rod 3. When the handle rod 5 slides downward, the sealing rod 2 is driven by the connecting rod 4 to rotate downward. The sealing rod 2 stops rotating downward when it rotates to a horizontal state under the limitation of the limiting structure, that is, when the sealing rod 2 closes the open lower end of the hooking frame 1. A connecting structure for connecting a safety rope is arranged at the lower end of the handle rod 5.

[0023] In order to facilitate the connection of the safety rope, the connecting structure for connecting the safety rope adopts a hanging ring 6 for hanging the safety rope. The hanging ring 6 is fixed at the lower end of the handle rod 5 by two rivets. By connecting the hanging ring 6 as a separate part with the handle rod 5, the complexity of the parts can be effectively reduced, and the separate machining and manufacturing of the hanging ring 6 or the handle rod 5 become easier. The rivet connection is firm and reliable, and can also be disassembled, replaced and maintained by tools.

[0024] In order to prevent the sealing rod 2 from continuing to rotate downward after closing the open lower end of the hooking frame 1, as shown in Figure 1As shown, the slide rail rod 3 is provided with a vertical front-to-back through limiting slot hole 301, and the handle rod 5 is provided with a limiting pin corresponding to the limiting slot hole 301. Through the cooperation of the limiting pin and the limiting slot hole 301, as a limiting structure between the handle rod 5 and the slide rail rod 3, the rotation angle of the sealing rod 2 is limited, so that the sealing rod 2 does not continue to rotate downward after closing the lower end opening of the hooking frame 1, and when the climber falls accidentally, the sealing rod 2 is ensured not to exceed the rotation angle downward, ensuring safety. In this example, the limiting pin can be a pin or a screw.

By arranging the upper end of the slide rail rod 3 in the limiting slot of the connecting block 7 and fixing it by two rivets, the connection is firm, stable and reliable. In this example, the connecting groove 702 can be located on one side of the hooking frame 1.

[0027] In order to facilitate manufacturing, the hooking frame 1 is a rectangular frame with four corners. The rectangular frame can conveniently realize the hooking structure, well adapt to the shape of the tower angle steel 8, improve the adaptability and practicality of the tool, and the structure is simple and easy to process and manufacture.

[0028] In this example, the width of the lower end opening of the hooking frame 1 is 1.5 times the cross-sectional width of the tower angle steel 8. The size of the lower end opening is reasonably optimized, which can conveniently hang in or separate from the angle steel 8.

[0029] In this example, the vertical frame height of the hooking frame 1 is 1.5 times the cross-sectional width of the tower angle steel 8. The frame height is reasonably optimized, so that the angle steel 8 can fully enter the inside of the hooking frame 1, effectively improving the safety of the hooking.

[0030] In this example, when the sealing rod 2 rotates upward to the top of the hooking frame 1, the inner top width of the hooking frame 1 on the right side of the sealing rod 2 is 1.3 times the cross-sectional width of the tower angle steel 8, and the vertical distance between the sealing rod 2 and the right side of the opening of the hooking frame 1 is 1.3 times the cross-sectional width of the tower angle steel 8. The size is reasonably optimized, and when hooked on the tower angle steel 8, the width size of the top can make the angle steel 8 connect with the inner top of the hooking frame 1, which can effectively improve the safety and stability of the hooking, and the vertical distance between the sealing rod 2 and the right side of the opening of the hooking frame 1 is optimized to make the tower angle steel 8 easily enter the right inner upper space of the hooking frame 1, and when the sealing rod 2 rotates downward, it will not collide with the tower angle steel 8, effectively improving the safety and convenience of operation.

[0031] When the construction personnel climbs the tower, the safety rope on the body is hung on the hanging ring 6 hung on the lower end of the handle rod 5, the handle rod 5 is pushed upward to the top, and the sealing rod 2 is in a fully open state, and when climbing, the hooking frame 1 is hooked on the angle steel 8 of the tower with one hand, and then the handle rod 5 is grabbed with one hand to take off from the angle steel 8, and then the higher tower angle steel 8 is hooked, and gradually climbs upward, when the accidental falling occurs, the human body falls rapidly, the safety rope on the body pulls downward, the safety rope pulls the handle rod 5 downward, and the sealing rod 2 is driven downward by the connecting rod 4 mechanism to rotate and close the lower end opening of the hooking frame 1, so that the tool is safely and reliably hung on the tower angle steel 8, which can effectively prevent the hooking frame 1 from falling off the angle steel 8, prevent the climber from falling downward, effectively improve the safety of tower climbing, the tool has simple structure, convenient manufacturing, low manufacturing cost, and can be operated with one hand, which provides safety protection for construction personnel.
