Tool for fastening flange bolts for steel utility poles

Abstract

The invention discloses a tool for fastening flange bolts for steel utility poles. The tool comprises an operating lever and a connecting part. The connecting part comprises a plate body; a power gear, a transmission gear and a bolt gear are sequentially tiled on the back of the plate body; the power gear meshes with the transmission gear; the transmission gear meshes with the bolt gear; a center shaft of the power gear penetrates the plate body until the front of the plate body; the corresponding position of the front of the plate body is provided with a lever bolt integrally connected with the center shaft of the power gear; the center of the bolt gear is in a hollow structure and is provided with a flange bolt hole fitting the flange bolt; the operating lever comprises a handle portion and a main portion connected with each other; the main portion is provided with a right-hexagonal lever bolt hole which fits the lever bolt.

Description

technical field [0001] The invention relates to a tool for fastening flange bolts of electric steel rods. Background technique [0002] The flange bolts of electric steel poles have a large diameter, generally above M30. At the same time, because they must be operated at high altitudes, they cannot be deployed like ground operations. There are two major difficulties in tightening such bolts with traditional tools: 1) Restricted by the flange reinforcement ribs , The effective fastening angle of the traditional wrench is only about 30 degrees, and the effective standing position of the high-altitude workers is limited. 2) Constrained by the high-altitude working environment, it is impossible to achieve the goal of labor saving by lengthening the length of the arm. Human arm strength has a certain limit. In this case, the tightening torque transmitted to the bolt by using traditional tools is limited. , Large-diameter bolts (such as bolts above M48) are difficult to tighten i...
