An electric bolt cutter

Abstract

The invention relates to an electric wire cutting clamp which comprises a supporting rod and a connection piece arranged at the front end of the supporting rod. The connection piece is provided with a four-bar linkage mechanism and a clamp head assembly in transmission connection with the four-bar linkage mechanism. The connection piece and the supporting rod are provided with a crank sliding block mechanism connected with the four-bar linkage mechanism, a ball screw mechanism in transmission connection with the crank sliding block mechanism and a motor drive mechanism in transmission connection with the ball screw mechanism in sequence from front to rear; and the motor drive mechanism drives the ball screw mechanism, the crank sliding block mechanism, the four-bar linkage mechanism and the clamp head assembly in sequence to cut off a wire placed in the clamp head assembly. Compared with the prior art, the electric wire cutting clamp is high in cutting force, easy in operation, high in work efficiency, good in convenience, large in length and small in weight, manpower is saved, and safety and efficiency of overhead work are effectively guaranteed.

Description

technical field [0001] The invention belongs to the technical field of electric power construction and relates to an electric bolt cutter. Background technique [0002] In electrical construction work, it is often necessary to cut wires without interruption of power supply. Bolt cutters are a commonly used tool that can cut wires relatively easily. Existing bolt cutters are mainly divided into two classes, namely large mechanical bolt cutters and small manual bolt cutters. Among them, large-scale mechanical bolt cutters are often driven by hydraulic pressure, which is bulky, heavy, inconvenient to move, lacks flexibility, and limited in scope of use; the design of small manual bolt cutters is derived from the principle of scissors, and has the advantages of simple operation, convenient use, Small size and other advantages, you can carry it with you, but small manual bolt cutters can only cut thinner wires. When encountering thicker metal wires, it is more difficult for sma...

Problems solved by technology

However, during the use of the electric bolt cutter, the main motor needs to have a relatively large torque to provide sufficient shearing force, which not only increases the cost of the main motor, but also increases the size and weight of the main motor. Increase the overall volume and weight of the electric bolt cutter, which limits the further improvement of its portability
