The invention discloses a detachable auxiliary tree cutting pull rod which is characterized by comprising a pull rod body and a clamp. The clamp comprises a pedestal, an upper clamping piece, a lower clamping piece, an elastic piece, an electromagnet and a controller. The pedestal is mounted at the first end of the pull rod body, and a mounting cavity is formed in the pedestal. The first end of the upper clamping piece is connected with the pedestal, and the second end is spaced from the pedestal. The first end of the lower clamping piece extends into the mounting cavity, and the second end of the lower clamping piece is located between the pedestal and the second end of the upper clamping piece. The electromagnet is arranged in the mounting cavity and is used for attracting the first end of the lower clamping piece. The two ends of the elastic piece are connected with the pedestal and the second end of the lower clamping piece correspondingly, and the elastic piece is used for providing elastic force close to the upper clamping piece for the lower clamping piece. The controller is arranged on the pull rod body and is used for controlling the magnetic strength of the electromagnet. According to the detachable auxiliary tree cutting pull rod, the electromagnet and the elastic piece are matched to control the lower clamping piece to be close to or away from the upper clamping piece, so that opening and closing of a clamp composed of the upper clamping piece and the lower clamping piece are controlled, and the risk that branches are unhooked and contact wires can be reduced.
Description
technical field [0001] The present application relates to the technical field of insulating pull rods, in particular to a detachable auxiliary tree-cutting pull rod. Background technique [0002] Trees can benefit human beings, green the environment and purify the air. However, if trees grow below and near the transmission and distribution overhead lines, they can also bring accident hazards to the safe operation of overhead power lines. For example, when the tree trunk is wet by rain, the tree becomes a conductor. If a branch touches the single-phase conductor, it may cause a single-phase ground fault on the line. Wire, then the two wires will discharge the tree, and under the characteristics of electricity, the same sex repels and the opposite sex attracts, an arc will be generated, which will cause an arc short circuit. Therefore, technology is needed to trim trees near overhead lines. [0003] In the process of pruning trees, when the branches are too close to the ove...
