Problems solved by technology

[0002] When the 500 kV transmission line four-split conductor spacer is repaired and replaced, the pin B needs to be removed, and because the conductor clamp cover clamps the conductor C, there is an elastic washer D inside, which compresses the conductor on the conductor clamp cover and After installing the pin B, due to the tension and elasticity of the elastic washer D, the wire collet cover has a tight force on the pin B, so that it will be very laborious to disassemble and install the pin B, which is an urgent problem. technical issues

Embodiment 1

[0032] State without temporary locking device and insertion rod (11): When in use, fasten the U-shaped clamping part (2-1) to the clamp neck (6) of the wire clamp cover (5), and tightly clamp the upper handle (1) and the lower handle (2), remove the force of the wire collet cover (5) on the pin B, and then remove the pin B with the other hand, and then loosen the upper handle (1) and the lower handle ( 2), open the wire clamp cover (5) to complete the disassembly.

Embodiment 2

[0034] There is a temporary locking device but no insertion rod (11): When in use, buckle the U-shaped clamping part (2-1) on the chuck neck (6) of the wire chuck cover (5), so that the toothed hook (7) Pass through the through hole of the lower handle (2) and engage (hook) with the oblique ratchet (8), then tightly clamp the upper handle (1) and the lower handle (2), in the process of gradually clamping The ratchet hook (7) gradually moves down and engages the oblique ratchet (8) downwards sequentially, because a ratchet hook (7) and the oblique ratchet (8) form a structure principle same as that of the ratchet ratchet. structure, the oblique ratchet (8) is inclined downwards, and the toothed hook (7) is also a hook compatible with the oblique ratchet (8) inclination direction, and has the effect of a torsion spring (9), so the ratchet When the tooth hook (7) moves down, it will automatically jump to the next ratchet engagement, so that the upper handle (1) and the lower hand...

Embodiment 3

[0036] State with temporary locking device and insertion rod (11): When in use, fasten the U-shaped clamping part (2-1) to the chuck neck (6) of the wire chuck cover (5), so that the toothed hook (7) wears Go through the through hole (2-2) of the lower handle (2) and engage with the oblique ratchet (8), so that the insertion rod (11) is inserted into the oblong hole (10) for positioning, and then tightly clamp the upper handle (1 ) and the lower shank (2), the ratchet hook (7) gradually moves down and engages the oblique ratchet (8) downwards in the process of gradual clamping, because the ratchet hook (7) and the oblique ratchet (8) form a structure with the same principle as the ratchet ratchet (one-way movement structure, in this application, it can only move downward, and it will be hooked upward), and the oblique ratchet (8) is downward Inclined, the toothed hook (7) is also a hook compatible with the inclined direction of the inclined ratchet (8), and has the effect of a...

Abstract

A special tool for replacing a quad-bundled conductor spacer comprises an upper handle (1) and a lower handle (2), and the front end of the upper handle (1) and the front end of the lower handle (2) are movably connected through a connecting shaft (3) to form an openable structure. The tool is simple and light in structure and convenient to operate, and can be applied to both JZX4-type and JZF4-type quad-bundled conductor spacers.

Description

technical field [0001] The present invention is called the special tool for replacing the four-split wire spacer, and is a maintenance tool for 500 kV transmission lines. Background technique [0002] When the 500 kV transmission line four-split conductor spacer is repaired and replaced, it is necessary to remove the pin B, and because the conductor clamp cover clamps the conductor C, there is an elastic washer D inside, which compresses the conductor on the conductor clamp cover and After installing the pin B, due to the tension and elasticity of the elastic washer D, the wire collet cover has a tight force on the pin B, so that it will be very laborious to disassemble and install the pin B, which is an urgent problem. technical problems. Contents of the invention [0003] Purpose of the invention: [0004] The invention provides a special tool for replacing four-split wire spacer rods, and aims to solve the existing problems in the past. [0005] Technical solutions: ...
