Problems solved by technology

[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 fasten in place

Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings.

[0022] Such as Figure 1 to Figure 4 Shown is a power steel rod flange bolt tightening tool, including operating wrench and connecting parts;

[0023] Such as figure 1 and figure 2 shown. The connecting part includes a plate-shaped body 1, and the back of the plate-shaped body is sequentially arranged with a power gear 2, a transmission gear 3, and a bolt gear 4; the power gear 2 meshes with the transmission gear 3, and the transmission gear 3 and the bolt Gear 4 is meshed;

[0024] The central axis of the power gear 2 passes through the plate-shaped body 1 to reach the front of the plate-shaped body, and the corresponding position on the front of the plate-shaped body 1 is provided with a wrench bolt 5 connected with the central axis of the power gear;

[0025] The central position of the bolt gear 4 is a hollow structure, and there are flange bolt holes 6 for m...
