Embodiment

[0023] Example: such as Figure 1-5 As shown, the present invention is a special tool for replacing linear insulators of transmission lines, including an adjustment mechanism 1, an extension mechanism 2 and a clamping mechanism 3. Two extension mechanisms 2 are installed symmetrically on both sides of the adjustment mechanism 1, and the extension mechanisms 2 are installed There are two clamping mechanisms 3 .

[0024] Among them, the adjustment mechanism 1 includes a collet 11, a No. 1 threaded rod 12, an adjustment frame 13, a No. 1 threaded sleeve 14, a No. 1 limit block 15, a rotary sleeve 16, a connecting rod 17, a No. 2 limit block 18, and a fixed rod. 19. Plywood 110, No. 2 threaded rod 111 and No. 1 handle 112. The upper and lower sides of the adjustment frame 13 are respectively fixedly interspersed with No. 1 threaded sleeve 14 and rotating sleeve 16, and No. 1 threaded sleeve 14 is internally threaded with No. 1 threaded rod 12. The top of No. 1 threaded rod 12 is ...

Abstract

The invention discloses a special tool for replacing a linear insulator of a power transmission line. The special tool comprises an adjusting mechanism, extending mechanisms and a clamping mechanism,two extending mechanisms are symmetrically mounted at the two sides of the adjusting mechanism, and each extending mechanism is provided with two clamping mechanisms. The adjusting mechanism comprisesa chuck, a first threaded rod, an adjusting frame, a first threaded sleeve, a first limiting block, a rotating sleeve, a connecting rod, a second limiting block, a fixing rod, a clamping plate, a second threaded rod and a first handle, and the first threaded sleeve and the rotating sleeve are fixedly inserted into the upper side and the lower side of the adjusting frame correspondingly. The special tool for replacing the linear insulator of the power transmission line has the characteristics of being compact and reasonable in structure and being safe and convenient to replace the insulator, during use, the adjusting mechanism can perform angle and height adjustment, and the extending mechanisms can perform position change in the horizontal direction and the vertical direction, so that theadjustment requirements for different heights and different distances are met, and the clamping mechanism can effectively limit the insulator umbrella skirts.

Description

technical field [0001] The invention relates to a tool, in particular to a special tool for replacing linear insulators of transmission lines, which belongs to the technical field of electric power construction. Background technique [0002] An insulator is a special insulation control that can play an important role in overhead transmission lines. Insulators were mostly used on utility poles in the early years, and gradually developed in the high-voltage wire connection tower. There are many disc-shaped insulators hanging on one end of the tower. It is In order to increase the creepage distance, it is usually made of glass or ceramics. [0003] Linear insulators made of glass or ceramics are heavy and bulky. During power laying and maintenance work, it is extremely dangerous for operators to replace insulators with their hands. Falling accidents will endanger the lives of people on the ground. Contents of the invention [0004] The purpose of the present invention is to...
