A pipeline walking trolley

Abstract

The application relates to a pipeline walking trolley and relates to the technical field of pipeline detection and maintenance equipment, which comprises a trolley body, a connecting mechanism, auxiliary walking mechanisms and the like. The connecting mechanism comprises a central connecting rod and three connecting assemblies which are arranged at intervals in the circumferential direction of the central connecting rod, one end of each connecting assembly is connected with the central connecting rod, the distance between the other end of each connecting assembly and the central connecting rod is adjustable, and the other end of one of the connecting assemblies is connected with the trolley body. The auxiliary walking mechanisms are arranged correspondingly to the other two connecting assemblies, the auxiliary walking mechanisms are connected with the other end of the corresponding connecting assemblies, and are used for abutting against the inner wall of a pipeline. Since the auxiliary walking mechanisms are connected with the other end of the corresponding connecting assemblies, the distance between the other end of each connecting assembly and the central connecting rod is adjustable, the trolley can be adjusted according to the diameter of the pipeline, the trolley is suitable for pipelines with various diameters, the applicability is improved, the trolley in the prior art is difficult to adapt to the change of the diameter of the pipeline, the applicability is low, and the problem that the detection result is affected is solved.
