Grounding grid reinforcing steel bar bending device

Abstract

The invention discloses a grounding grid reinforcing steel bar bending device. A front fixing plate and a back fixing plate each comprise a top connecting arm, a left support arm and a right support arm, each left support arm and the corresponding right support arm are distributed in a splayed manner, and the upper end of each left support arm and the upper end of the corresponding right support arm are connected to the two ends of the corresponding top connecting arm correspondingly; the lengths of the left support arm and the right support arm of the back fixing plate are larger than those of the left support arm and the right support arm of the front fixing plate, the lower portions of the left support arm and the right support arm of the back fixing plate are downwards bent to form vertical bending parts, and the front fixing plate and the back fixing plate are connected through front and back fixing plate bolts; the lower portions of the vertical bending parts of the left support arm and the right support arm are hinged to reinforcing steel bar rotation box iron through rotating pins, a lead screw base is connected between the top connecting arms of the front fixing plate and the back fixing plate, and a through hole is formed in a reinforcing steel bar fixing frame; and the lower portion of the lead screw is fixedly provided with a lead screw penetrating needle which extends into the reinforcing steel bar fixing frame, and a bearing is arranged between the lead screw penetrating needle and the reinforcing steel bar fixing frame. The grounding grid reinforcing steel bar bending device is simple in structure and convenient to carry, and reinforcing steel bars can be quickly and effectively bent and machined.

Description

technical field [0001] The invention relates to a steel bar bender for a grounding grid, which belongs to the field of mechanical equipment. Background technique [0002] During the long-term operation of high-voltage transmission lines, the safety function of the grounding grid cannot be ignored. When laying the grounding grid, the steel bars on the surface of the grounding grid should be bent. Since there is no bending tool specially used for the grounding grid steel bars in the power system, All parts that need to be bent are formed by manual bending, sledgehammer knocking or oxygen welding and baking; the efficiency of manual bending and oxygen welding and baking is very low, time-consuming and laborious; Under external operating conditions, it is easy to corrode and break the grounding grid in a short period of time, affecting the safe operation of the line, and it is easy to injure people, posing safety hazards; in addition, although there are electric steel bars in th...
