Embodiment Construction

[0059] The core of the present invention is to provide a pinch wheel mechanism to ensure that the driving wheel of the line patrol robot has the function of overcoming obstacles and improve the application range of the line patrol robot;

[0060] Another core of the present invention is to provide a traveling wheel set mechanism with a pinch wheel mechanism.

[0061] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0062] see figure 1 , figure 1 Schematic diagram of the structure of the pinch wheel mechanism prov...

Abstract

The invention discloses a pinch roller mechanism. The pinch roller mechanism comprises a fixed box, a lifting driving device arranged on the fixed box and a pinch roller set which is connected with the lifting driving device and is driven by the lifting driving device to rise and fall, wherein the pinch roller set at least comprises a pinch roller. When the pinch roller mechanism works, the pinch roller of the pinch roller set is compressed to the lower side of a line, and an inspection robot can walk through cooperation between the pinch roller and a driving wheel mechanism; when one pinch roller mechanism of the inspection robot approaches to a barrier and can not pass through, the pinch roller set is driven by the lifting driving device to move downwards, and then compression of the line is released; the inspection robot walks continuously, the lifting driving device drives the pinch roller set to move upwards when the pinch roller mechanism bypasses the barrier, and then compression of the line is achieved. According to the pinch roller mechanism, an obstacle crossing function is achieved, and the application range of the inspection robot is widened. The invention further discloses a traveling wheel set mechanism provided with the pinch roller mechanism.

Description

technical field [0001] The invention relates to the technical field of line inspection robots, and more specifically, to a walking wheel mechanism. Background technique [0002] The use of high-voltage and ultra-high-voltage overhead power lines is the main way of long-distance power transmission and distribution, and the safe operation of high-voltage and ultra-high-voltage lines is the guarantee for long-distance power transmission. However, overhead transmission lines have been exposed to the field for a long time. Due to the impact of continuous mechanical tension, wind and sun, and material aging, damage such as broken strands, wear, and corrosion often occurs. It may expand, eventually leading to serious accidents and large-scale power outages, which will bring great economic losses and serious social impacts. [0003] In the early days, the traditional line inspection method used manual visual inspection and aircraft cruise. Manual visual inspection is often time-co...
