Description

Technical field: [0001] The invention relates to a human transport vehicle running in a large pipeline. Background technique: [0002] At present, the advanced detection method for the acceptance and pressure test of water supply and drainage pipelines is to conduct pressure tests at each pipeline interface. For example, Chinese patent CN1908610 internal pressure type pipeline joint pressure test method and device, it provides a kind of device for cement socket pipe joint pressure test. The device consists of a water injection pump, a pressure gauge, a sealing rubber ring and an expansion ring, as well as a water inlet pipe, an exhaust pipe and an exhaust valve. Among them, the expansion ring is spliced ​​into one by three curved steel plates with inlaid slits. The equipment and parts that make up the device must be assembled and disassembled in the pipeline. Up to now, there is no special vehicle for transporting equipment and parts in the pipeline, and it is very inconv...
