Connecting piece of fastening tool for electric steel pole flange bolt

Abstract

The invention discloses a connecting piece of a fastening tool for an electric steel pole flange bolt. The connecting piece comprises a plate-shaped body; a power gear, a transmission gear and a bolt gear are arranged in sequence on the back face of the plate-shaped body in a tiling manner; the power gear and the transmission gear are meshed, and the transmission gear and the bolt gear are meshed; the center shaft of the power gear passes through the plate-shaped body to reach the front face of the plate-shaped body; a spanner bolt connected with the center shaft of the power gear into a whole is arranged at a corresponding position on the front face of the plate-shaped body; the central position of the bolt gear is of a hollow structure, and a flange bolt hole matched with the flange bolt is formed in the central position of the bolt gear. Power is transmitted by adopting the combination of the three gears of the connecting piece, and thus, the goal of labor saving is achieved on the premise that a force direction or the length of a moment arm is not changed, and the requirement of the fastening torque of a large-diameter bolt is met; the force application point of an operation spanner is shifted to the outer side, and therefore the constraint and restriction of a flange reinforcing rib are ridded, and an effective fastening operation angle reaches 190 degrees.

Description

technical field [0001] The invention relates to a connecting piece of a power steel rod flange bolt fastening tool. 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...

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 fasten in place
