Embodiment 1

[0034] see figure 1 , this embodiment provides a heavy object fall prevention hook for pole and tower operations, which has a locked state and an unlocked state. The heavy object fall prevention hook mainly includes a housing 1, a hook body 2, a locking mechanism 4 and an unlocking mechanism 3. One end of the rope 6 is connected to the weight 7 , the other end passes through the casing 1 upwards and extends out of the casing 1 , and the hook body 2 is fixedly connected to the outside of the casing 1 . The locking mechanism 4 includes a pressing part 42 rotatably connected to the housing 1. In a locked state, the pressing part 42 can press the rope 6 against the inner wall of the housing 1. At this time, the rope 6 can only move upward. The unlocking mechanism 3 is arranged on the housing 1. In the unlocked state, the unlocking mechanism 3 can drive the pressing part 42 to rotate away from the rope 6 so that the rope 6 can move up and down, thereby adjusting the position of th...

Embodiment 2

[0049] This embodiment provides a heavy object fall prevention hook for pole and tower operations. The difference between this embodiment and Embodiment 1 is that:

[0050] like image 3 As shown, the second switch 322 is a toggle switch, which is arranged on the top surface of the housing 1 and can be cylindrical or wedge-shaped in shape. Optionally, the upper end surface of the second switch 322 is provided with anti-slip ribs. A Z-shaped connecting rod 324 and a first elastic member 321 are disposed inside the housing 1 . The Z-shaped connecting rod 324 includes a first short side, a long side and a second short side, the first short side and the second short side are vertically connected to the two ends of the long side respectively, and the first short side and the second short side are vertically arranged , the long side is set horizontally. Optionally, the first short side is connected to the second switch 322 , and the second short side is located on the left side of...

Abstract

The invention belongs to the technical field of overhead distribution line construction equipment, and discloses a heavy object anti-falling hook for tower operation. The hook comprises a shell, a rope connected with a heavy object and penetrating through the shell, a hook body, a locking mechanism and an unlocking mechanism. The locking mechanism comprises a pressing part rotationally connected with the shell, and in a locking state, the pressing part can press the rope against the inner wall of the shell, so that the rope can only move upwards; the unlocking mechanism is arranged in the shell, and in the unlocking state, the unlocking mechanism can drive the pressing part to rotate in the direction away from the rope, so that the rope can move up and down. The heavy object anti-falling hook can be operated with one hand, operation is easy, workers can conveniently assemble and disassemble heavy objects on a tower, the operation risk is reduced, and equipment safety is guaranteed.

Description

technical field [0001] The invention relates to the technical field of construction equipment for overhead power distribution lines, in particular to a heavy-object drop-preventing hook used for pole and tower operations. Background technique [0002] In the current power industry, during the construction of overhead power distribution lines, the staff need to use the anti-fall rope to tie the equipment and the nearby fixed components tightly before disassembling the equipment, so as to prevent the equipment from falling from the tower during the installation and disassembly process. , causing equipment damage or even casualties. During the assembly and disassembly process, according to the traditional construction method, the staff needs to free up both hands to realize the action of tying the rope, especially when installing the equipment, the staff needs to transfer the equipment to the pole tower, and at the same time perform the action of tying the rope to fix it, which...
