Straightening equipment based on bent steel bar in electric power tower

Abstract

The invention discloses a straightening device based on a curved steel bar in an electric power tower, which includes a backboard, a boss for placing steel bars on the side wall of the backboard, a guide block on the side wall of the backboard, and a guide block There is a movable rod on the top, the movable rod is connected with the guide block by thread, and the movable rod can move along the axis direction of the guide block when the movable rod is rotated. There is a pressure plate on the rod, and the pressure plate can rotate around the pressure rod; the top of the boss is provided with an arc-shaped groove, a movable plate and a fixed block, and a push rod is arranged on the fixed block, and when the push rod is rotated, the push rod can push the movable plate to move . The invention is simple in structure and easy to operate, and can straighten the bent steel bar. During the operation, the steel bar can be fixed on the boss, avoiding displacement or shaking during the straightening process, and ensuring the straight line of the steel bar after straightening. At the same time, the device is easy to carry and is suitable for field operations.

Description

technical field [0001] The invention relates to a steel bar processing device, in particular to a straightening device based on curved steel bars in a power iron tower. Background technique [0002] Transmission line towers are generally divided into five types according to their shapes: wine cup type, cat head type, upper type type, dry type type and barrel type. Replacement of conductor phase position towers), terminal towers and spanning towers, etc. Their structural characteristics are that various tower types are space truss structures, and the rods are mainly composed of single equilateral angle steel or combined angle steel, and the material is generally Q235 (A3F) And Q345 (16Mn), the connection between the rods is made of rough bolts, and the bolts are connected by shear force. The whole tower is composed of angle steel, connecting steel plates and bolts, and individual components such as tower feet are welded by several steel plates to form an assembly Therefore, ...

AI Technical Summary

Problems solved by technology

At present, artificial straightening or special straightening machines are generally used for straightening steel bars. The method of manual straightening needs to straighten both ends of the steel bars separately, and it is easy to scratch yourself during the straightening process. High efficiency, less labor cost, but generally large volume, when used outdoors, due to the limited space, it is not convenient to install the straightening machine in some places, and it is also not convenient to carry
