Embodiment 2

[0035] On the basis of Embodiment 1, a camera 39 is installed in the middle of the main base 1 , and a display 44 is provided outside the handle 34 , and the camera 39 and display 44 are respectively connected to the controller 37 through lines.

[0036] In this embodiment, the main base 1 is provided with a mount 40 , and the camera 39 is mounted on the mount 40 .

[0037] When the bolt pre-tightening device for high-voltage line drainage clamps according to the present invention is used, the nuts and bolt heads to be fastened are correspondingly rotated in the nut tightening mechanism and the bolt tightening mechanism, and moved to the two sides of the drainage clamps that need to be fixed. Between the two mounting plates, pass the end of the bolt through the through hole of the mounting plate, and open the device of the present invention by pressing a button, and the nut tightening mechanism will drive the nut in the rotating state to the bolt tightening mechanism under the ...

Abstract

The invention discloses a bolt pre-tightening device for a high-tension cable jumper conductor clamper, and belongs to the technical field of high-tension cable installation. The bolt pre-tightening device is innovatively characterized by comprising an L-shaped main base, wherein a moving mechanism is arranged on the main base; the bottom of the main base is provided with a grip assembly; the front and rear ends of the main base are provided with a nut tightening mechanism and a bolt tightening mechanism respectively; and the nut tightening mechanism is movably connected with the moving mechanism, and can move forwards and backwards along the upper surface of the main base under the action of the moving mechanism. The device is novel in design, simple in structure, small in size and relatively light in weight, can be carried away by only one person, is convenient to operate and use, and has a good effect and high practicability.

Description

technical field [0001] The invention belongs to the technical field of on-site installation of high-voltage lines, and in particular relates to a bolt pre-tightening device for high-voltage line drainage clamps. Background technique [0002] In the prior art, when the drain clamp in the high-voltage transmission line fails, maintenance personnel are required to immediately use tools to fasten the screw and nut of the drain clamp in a charged state to ensure safe operation of the line. At present, most of the tools used in live work are insulating wrenches and insulating sleeves. Each operation requires two insulating wrenches or insulating sleeves. One clamps the screw seat to prevent the screw from rotating, and the other clamps the nut. Turn clockwise to tighten the nut relative to the screw, but this tool needs to intermittently and continuously change the position of the clamping nut and pull it back and forth, so the fastening speed is slow, labor-intensive, low-efficie...
