Pipeline internal inspection robot

Abstract

The invention discloses a pipeline internal inspection robot. The pipeline internal inspection robot comprises a vehicle body with wheels and a lifting frame arranged on the vehicle body. The lifting frame comprises a base connected with the vehicle body, the base is rotationally connected with a connecting rod, and a camera assembly is arranged at the end, opposite to the base, of the connecting rod. The pipeline internal inspection robot is characterized in that the base can slide forwards and backwards relative to the vehicle body; a driving mechanism capable of driving sliding is arranged between the vehicle body and the base; the vehicle body is provided with a linkage part driving the lifting frame to ascend and descend so that the wheels on the vehicle body can be stressed in a more balanced mode. The pipeline internal inspection robot is effectively prevented from inclining forwards or turning over backwards, and continuous and stable work of the pipeline internal inspection robot is guaranteed.

Description

technical field [0001] The invention relates to a non-excavation technology, more specifically, it relates to a pipe endoscopic robot. Background technique [0002] With the rapid development of the country's economic construction, urban construction has also made great progress, and a large number of infrastructure constructions have also been promoted. As an important part of municipal infrastructure projects, urban water supply and drainage pipelines are also continuously dense and extended in cities and suburbs. Because the pipeline is underground and hidden, a large number of water supply pipelines have been laid for a long time, and the inner wall is corroded, which may easily cause pipeline damage, road surface subsidence, and gas leakage. While affecting the quality of life of residents, it also brings huge potential safety hazards, and the probability of pipeline failure in cities is very high. In view of the problems existing in pipelines and the environment in w...

Problems solved by technology

[0004] However, the above-mentioned patents have defects. When the camera assembly is rising or falling, the center of the camera relative to the base will change, which will easily lead to different forces on the front and back of the base. At the same time, the weight of the camera assembly accounts for a large part of the overall weight. When the wheels pass through obstacles, it is easy to cause forward or backward tilt, which affects the continuous work of the crawler
