Description

Foreign matter shearing device of transmission line maintenance device

technical field

The invention relates to a power transmission line maintenance device, in particular to a foreign matter shearing device of the power transmission line maintenance device.

Background technique

The most common defects in the operation and maintenance of overhead transmission lines are the foreign objects (advertising strips, balloons, etc.) entangled on the wires of the transmission line, and the damage caused by lightning strikes, external bursts, and fires in the wire racks. Most of them are in the wire racks. High-altitude parts are very harmful, and it is difficult for operators to find or eliminate the above-mentioned defects without entering the wires. There is a great limit to the use of live work to enter the wires, which is often restricted by the safety clearance of live work and cannot be carried out, and there is a greater risk In particular, access to broken strands or equipotential removal of foreign objects poses a great safety risk and is extremely labor-intensive. In the case of vertically arranged or crossed conductors, power outage operations are required, which reduces the reliability of power supply.

Contents of the invention

The purpose of the present invention is to overcome the deficiencies of the prior art, and to provide a method that can replace the operator to enter the wire for equipotential maintenance, realize the charged removal of foreign objects such as kites and advertising strips on the ground wire, and effectively liberate Manpower for high-altitude operations reduces the safety risk of operators, greatly improves the live operation rate of transmission line maintenance, and reduces the foreign body shearing device of the transmission line maintenance device for power outages.

A foreign matter shearing device of a power transmission line maintenance device, the key point of its structure is that the foreign matter shearing device includes a set of shearing knives composed of two moving and static blades, and the moving blades are driven by a driving device.

The shear knife composed of two blades combined with dynamic and static can easily trim and remove various foreign objects such as light and thin cloth-like objects such as advertising cloth, ropes, and agricultural greenhouse plastic films on the ground wire of the transmission line.

The movable blade is a rotary blade.

The rotary blade is a polygonal blade.

The rotary blade is an octagonal rotary blade.

In front of the shearing knife of the foreign matter shearing device, a storage device capable of storing foreign matter between the moving and stationary blade groups of the shearing knife is arranged.

The storage device is arranged in front of the shearing knife, which can cut foreign matter more conveniently and quickly.

The storage device is a "eight"-shaped storage device, one of which is installed on one side of the stationary blade, and the other is installed on the side of the moving blade.

Each side of the eight-shaped storage device is a structure with adjustable length.

With the structure of adjustable length, the size of the storage opening can be changed conveniently according to the situation of the foreign matter, so as to increase the scope of application of the shearing device.

The length-adjustable storage device either has a folded structure on its sides, or has a retracted structure on its sides.

The telescopic structure is that the side is composed of two components, and rows of sockets are arranged on the two components, and then the two components are respectively fixed on different sockets; It is composed of pipe fittings together, and threads are provided on the two-phase contact surfaces of the pipe fittings, so that the two pipe fittings can be locked in different positions.

The storage device can also be composed of a fork-type device driven by a driving device.

The driving device of the foreign matter shearing device is composed of a worm gear, the worm gear is connected with the rotating blade, and the worm gear is connected with the power source or other transmission devices.

The transmission device can be various belt transmissions, gear transmissions and the like.

The power source is a motor, a high-speed motor, or a special military-grade motor.

In summary, compared with the prior art, the present invention has the following advantages:

The foreign matter shearing device of the power transmission line maintenance device of the present invention adopts a motor-driven high-speed electric shear and a reasonable foreign matter storage structure. The electric shear adopts two sets of dynamic and static blades to cooperate, and the polygonal rotating blade and the static blade are used to form an ingenious electric scissors. It can be easily trimmed to remove foreign matter on the conductor and ground of the transmission line, and the "eight" shaped foreign matter storage device can gather the scattered foreign matter to the knife edge.
