Inspection robot camera lifting platform and cable trench inspection robot

Abstract

The invention discloses an inspection robot camera lifting platform and a cable trench inspection robot, and relates to the technical field of cable inspection, and the inspection robot camera lifting platform comprises a working unit, a four-bar linkage assembly and a straight stroke driving mechanism; the working unit comprises a camera and a pitching mechanism, and the pitching mechanism can drive the camera to generate pitching action; the four-connecting-rod assembly comprises an upper long connecting rod, a lower long connecting rod, a head-end short connecting rod and a tail-end short connecting rod, and the head-end short connecting rod, the upper long connecting rod, the tail-end short connecting rod and the lower long connecting rod are sequentially hinged through a horizontal shaft; the straight-stroke driving mechanism comprises a straight-stroke driving source, the four-connecting-rod assembly is hinged to the straight-stroke driving source through a hinged shaft of a head-end short connecting rod and an upper-portion long connecting rod, and the working end of the straight-stroke driving source is in sliding fit with the upper-portion long connecting rod and the head-end short connecting rod. The cable trench has the advantage of being capable of better adapting to the narrow and cramped cable trench environment.

Description

technical field [0001] The invention relates to the technical field of cable inspection, in particular to an inspection robot camera lifting platform and a cable trench inspection robot. Background technique [0002] The occurrence of cable trench fire is a gradual accumulation process. 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, if the temperature and smoke inside the cable trench can be effectively monitored in real time, the fire can be prevented before it happens. Although the monitoring problem of the cable trench has attracted people's attention, a proper and reasonable solution has not been found. Traditional cable trench inspections use manual inspections. At regular intervals, inspectors enter the tunnel and use temperature measuring instruments to manually ch...

Problems solved by technology

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

The cable trench inspection robot disclosed in this patent can operate through the wall through the cable trench, thereby avoiding many usage problems caused by the existence of the firewall, and then can complete the scheduled inspection tasks efficiently; its linear displacement components directly drive One of the force arms imitating the four-bar linkage assembly can also realize the controllable function of the camera's lifting height, but it will require a large installation space and movement space, and it is difficult to adapt to the narrow and cramped cable trench environment
