Self-propelled transmission line outgoing overhaul flying car

Abstract

The invention relates to a self-propelled transmission line outgoing overhaul flying car. The self-propelled transmission line outgoing overhaul flying car comprises a traveling mechanism and a car body mechanism. The traveling mechanism comprises a front driving wheel and a back driven wheel which can be suspended on a transmission line and are provided with line clamping grooves, wherein a hub motor capable of driving the front driving wheel is arranged in the front driving wheel, the front driving wheel and the back driven wheel are arranged in a wheel frame, and a support frame is arranged at the bottom of the wheel frame; the car body mechanism comprises a car frame, the car frame is suspended on the support frame, a handle is arranged at the upper end of the car frame, a reversing switch is arranged at the inner side of the handle, and the car frame is provided with a pedal plate, a seat pad and battery components; and an upper wheel is arranged above the traveling mechanism and is connected with the wheel frame by virtue of an upper wheel frame. The self-propelled transmission line outgoing overhaul flying car provided by the invention has the advantages of being easy, convenient and flexible to operate, reducing the power failure, improving the reliability of line operation, enhancing the running capability of a powder grid, improving the working efficiency, reducing the cost, reducing the labor intensity and being suitable for overhauling vertical twin bundled lines.

Description

[0001] technical field [0002] The invention relates to a tool for overhauling an electric overhead transmission line, in particular to a self-propelled flying car for overhauling an electric transmission line used in the transmission line. Background technique [0003] In the power system, the overhead transmission line is set outdoors, which is easily affected by various internal and external factors, such as being damaged by wind, lightning strikes, floating foreign objects, and wild birds, causing the anti-vibration hammer on the ground wire to run out and break the strands. If the impact is not eliminated in time, the ground wire will be worn out, the line will be short-circuited and tripped, and the line will be disconnected, causing line accidents and affecting the safe operation of the line. In order to ensure the safety and reliability of power supply, it is necessary to eliminate the occurrence of these situations. At present, The maintenance of overhead transmiss...

[0003] In the power system, the overhead transmission line is set outdoors, which is easily affected by various internal and external factors, such as being damaged by wind, lightning strikes, floating foreign objects, and wild birds, causing the anti-vibration hammer on the ground wire to run out and break the strands. If the impact is not eliminated in time, the ground wire will be worn out, the line will be short-circuited and tripped, and the line will be disconnected, causing line accidents and affecting the safe operation of the line. In order to ensure the safety and reliability of power supply, it is necessary to eliminate the occurrence of these situations. At present, The maintenance of overhead transmission lines is usually handled by the traditional soft ladder outlet method. During maintenance, the soft ladder frame is placed on the overhead ground wire, and the operator leans on the soft ladder frame in a standing or sitting position, and uses his own strength to pull the wires by hand Drive the ladder frame forward, and eliminate defects when going out

When dealing with defects over a long distance of more than 5 meters, the staff travel along the line not only at a slow speed, but also take a long time to get out of the line, consume a lot of physical strength, work efficiency is low, and the psychological pressure of the personnel is relatively high; the operators who perform maintenance on the ladder will also There are high security risks

In addition, ordinary outgoing ladders can only be used for maintenance of a single line. For vertical double-split transmission lines, the weight of the maintenance personnel acts on one cable and the single cable sags, which will make the two lines of the double split The cable distance is too large, it is difficult to repair the parallel double-split cables at the same time
