A ground wire tension pole tower bridge crossing device for a power transmission line inspection robot

Abstract

The invention relates to an auxiliary device of an inspection robot of a power transmission line and particularly relates to a gap bridge device at a ground wire strain tower section. The device comprises a flexible gap bridge mechanism, a connection locating mechanism used for fixedly connecting the flexible gap bridge mechanism and two strain clamps, and a connection locating component used for fixedly connecting the gap bridge device and a strain tower head cross arm; and when the robot detects the strain gap bridge, a locking arm joint is loosened, so that two wheels can adapt to the shape of the gap bridge mechanism to roll on the gap bridge device so as to arrive at a ground wire on the other side of the tower, namely penetrating and passing through the strain tower. The device is provided with two sections of flexible spherical hinge components and two regulating mechanisms, so that the device can be arranged on different types of strain towers with different rotating angles and can adapt to wire galloping. The device is low in cost and simple in installation; and the robot can efficiently, safely and reliably penetrate through the strain tower by virtue of the device.

Description

technical field [0001] The invention relates to an auxiliary device for a power transmission line inspection robot, in particular to a bridge crossing device for a ground wire tension pole and tower section. Background technique [0002] Line inspection with line inspection robots can reach the lines that are difficult to reach manually, improve inspection efficiency, greatly reduce the labor intensity of inspection and the potential risks of manual inspection, which is the inevitable development of robot technology and power inspection technology trend. In particular, the rolling inspection robot has a lot of practical space, but the obstacle surmounting problem of the inspection robot has become a major problem in the application of the robot in the inspection of high-voltage transmission lines. Especially for the tension pole tower section, the transmission line is separated by the tension pole tower to separate the lines on both sides, which is even more inconvenient fo...

AI Technical Summary

Problems solved by technology

Will lead to increase the robot's overall size, but also increase the weight of the robot

This is not only inconvenient for robot transportation and hanging piles, but also greatly increases the design and manufacturing costs of the robot

[0005] To sum up, due to the complexity of the line structure of the ground wire tension section, it is impossible to use the method of double-arm staggered climbing to overcome obstacles. However, it is difficult to control the robot's speed by improving the structure of the robot itself to solve the above problems. Various issues such as structural size, weight, cost and inspection efficiency

This makes it meaningless to use robots to inspect transmission lines
