Cable trench inspection robot

Abstract

The invention belongs to the technical field of cable inspection, and particularly relates to a cable trench inspection robot. The cable trench inspection robot comprises a vehicle body and a workpiece lifting platform installed on the vehicle body. The workpiece lifting platform comprises a working unit and a four-connecting-rod assembly used for jacking the working unit. A lower guide groove is formed in a short connecting rod at the head end of the four-connecting-rod assembly, an upper guide groove is formed in a long connecting rod at the upper part, and the upper guide groove and the lower guide groove are matched to form a splayed guide part with an opening facing a short connecting rod at the tail end; the working end of a straight stroke driving source horizontally extends towards the two sets of guide grooves to form guide blocks, and therefore the guide blocks, the upper guide groove and the lower guide groove form a guide rail sliding block matching relation at the same time. According to the cable trench inspection robot, through-wall operation can be achieved through the cable trench, so that many use problems caused by the existence of a firewall are avoided, and a predetermined inspection task can be completed efficiently.

Description

technical field [0001] The invention belongs to the technical field of cable inspection, and in particular relates to a cable trench inspection robot. Background technique [0002] The occurrence of fires in cable tunnels is a process of gradual accumulation. With the increase of time, due to the aging of the insulation layer, the accumulation of dust and oil, and the looseness of the intermediate joints, the local temperature of the cable will gradually rise, which will cause a fire. Before the accident occurs, if the temperature and smoke inside the cable tunnel can be effectively monitored in real time, the fire can be prevented before it happens. Although the monitoring problem of cable tunnel has attracted people's attention, but has not found a proper and reasonable solution. [0003] Traditional cable tunnels are manually inspected. At regular intervals, inspectors enter the tunnel and use temperature measuring instruments to manually check the temperature of the i...

Problems solved by technology

However, the disadvantages of thermal wires are: firstly, the cables located on both sides of the cable tunnel are bundled and arranged in bundles, and the thermal wires can only monitor the high temperature changes of the adjacent cables that are close to each other, and the thermal wires located at the farthest end The temperature change monitoring effect of the cable is very poor

The existence of the firewall makes it necessary to repeatedly take out the tunnel inspection robot from the previous tunnel unit-reset the cover plate on the previous tunnel unit-remove the cover plate of the new tunnel unit-replace the tunnel inspection robot every time it inspects the tunnel inspection robot. The process of entering the tunnel inspection robot is extremely complicated and requires a lot of physical labor, which obviously seriously restricts the actual inspection efficiency.

On the other hand, as stated above, the cables in the cable tunnel are arranged in bundles, so there is a certain height. The traditional tunnel inspection robot can inspect the height constant, and there must be some dead ends of the cables that cannot be inspected, resulting in inspection loopholes. ,There are security risks
