Problems solved by technology

[0002] Accurate measurement of grounding resistance can verify whether the design of the grounding system is reasonable, detect changes or defects in the grounding system in time, and avoid economic losses or accidents that may be caused by unqualified grounding. Usually, we use a grounding shaker to measure grounding resistance. During the process, the grounding wire needs to be removed from the concrete pole, but after dismantling, it is difficult to fix the grounding wire on the concrete pole after the measurement. After the grounding resistance measurement, the bolt cannot be fixed directly because the grounding wire sinks. In the hole, it is impossible to lift the grounding wire to the proper position without the help of tools and manpower. In the traditional operation process, the method of hand hoist is generally used to solve the problem, but this method has the following disadvantages: 1. The hand hoist is heavy and the operation is cumbersome ;2. When there is no hanging point, you have to rely on the rope as the hanging point, and it is not stable; 3. The efficiency is low and time-consuming; 4. The use effect is not good, and it is not convenient to attach the ground flat iron to the concrete pole

Abstract

The invention discloses a lifting tool for grounding wire flat iron of a concrete pole for a power transmission line. The lifting tool for the grounding wire flat iron of the concrete pole for the power transmission line comprises a support, a pry bar and a pry bar force-bearing component. The support comprises a long pole bolt, round steel and a base plate. One end of the round steel is welded to the base plate, the other end of the round steel is connected with one end of the long pole bolt, and the other end of the long pole bolt is connected with the pry bar force-bearing component. A nut is arranged on the joint of the long pole bolt and the round steel. The pry bar force-bearing component is connected with the pry bar. 45#steel is adopted to serve as the round steel. An internal thread is arranged in the round steel, and the dimension of the internal thread is matched with the size of an external thread on the long pole bolt. The long pole bolt is connected with the round steel through the external thread and the internal thread. The length of the pry bar can be adjusted. An anti-slip sleeve is arranged on the handhold portion of the pry bar, and a U-shaped frame with a certain width and a certain thickness is designed on the portion, making contact with the pry bar force-bearing component, of the pry bar. The lifting tool for the grounding wire flat iron of the concrete pole for the power transmission line is easy and convenient to operate and high in safety.
