Inspection robot

Abstract

The invention discloses an inspection robot which comprises two inspection robot bodies. Each inspection robot body comprises a walking wheel set mechanism, a clamping mechanism and a pitch change mechanism. Each pitch change mechanism comprises a base, a slide base arranged on the base, a screw rod arranged on the base, a nut matched with the screw rod in a threaded mode and connected with the slide base and a pitch change drive device arranged on the base. Each clamping mechanism comprises a supporting box arranged on the corresponding base, a supporting frame arranged on the supporting box, a first rotary shaft, a second rotary shaft, a clamping drive device, a first clamping jaw and a second clamping jaw, wherein each first rotary shaft and each corresponding second rotary shaft are arranged on the corresponding supporting frame and are connected through a transmission mechanism, each clamping drive device drives one of the corresponding first rotary shaft and the corresponding second rotary shaft to rotate, each first clamping jaw is fixed to the corresponding first rotary shaft, each second clamping jaw is fixed to the corresponding second rotary shaft, and the first clamping jaws and the second clamping jaws can be hung on a line after being crossed and can be disengaged from the line after being separated. The inspection robot can achieve the effect of crossing over a barrier through motions of the pitch change mechanisms.

Description

technical field [0001] The present invention relates to the technical field of line inspection robots, and more specifically, relates to a line inspection robot with an obstacle-surmounting function. 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 aircraf...

Problems solved by technology

However, there must be some obstacles on the line. For regular obstacles, the driving wheel mechanism can also realize the obstacle-surpassing function through the opening and closing of the driving wheels, but for some irregularly arranged obstacles in the line, only through the opening and closing of the driving wheels It is also difficult to achieve obstacle crossing, which limits the application range of line inspection robots
