A self-propelled walking pipeline inner wall spraying vehicle and using method thereof

Abstract

A passive spraying vehicle for the inner wall of a walking pipeline and its use method. The spraying vehicle includes a hydraulic motor and a first chassis and a second chassis arranged on both sides of the hydraulic motor. The first chassis is provided with an energy accumulator and an unloader. The accumulator and the unloader are connected to the hydraulic motor, the hydraulic motor is equipped with a rotating disk, the side wall is equipped with a spray pipe, the bottom of the second chassis is equipped with a second wheel set and a third wheel set, and there is a Transmission shaft, one end of the transmission shaft is provided with a first bevel gear meshing with the second bevel gear of the second wheel group, and the other end is provided with a pulley meshing with one end of the belt, and the other end of the belt is connected with the hydraulic motor. The energy device inputs high-pressure paint into the hydraulic motor, and the high-pressure paint flows through the rotating disc in the hydraulic motor and is sprayed out through the spray pipe to spray the pipeline. At the same time, torque is generated to drive the hydraulic motor to rotate, and then drive the spraying vehicle in the pipeline. Self-propelled, not only can spray evenly, but also does not need electric drive, which is safe and labor-saving.

Description

technical field [0001] The invention relates to the technical field of pipeline protection, in particular to a self-propelled walking pipeline inner wall spraying vehicle and a use method thereof. Background technique [0002] In modern industry and construction, pipe is a widely used building material. In order to adapt the pipeline to different fluid qualities, a variety of special coatings are usually sprayed on the inner wall of the pipeline, so that accidents such as leakage and cracking will not occur when the pipeline flows through high-temperature or highly corrosive liquids. [0003] Spraying paint on the inner wall of various pipelines mainly depends on the inner wall spraying machine of the pipeline. At present, there are two main types of spraying machines on the inner wall of the pipeline in China. One is the spraying machine that uses electricity as energy, and the other is the spraying machine that is driven by manpower and powered by a hydraulic pump. Machin...

[0003] Spraying paint on the inner wall of various pipelines mainly depends on the inner wall spraying machine of the pipeline. At present, there are two main types of spraying machines on the inner wall of the pipeline in China. One is the spraying machine that uses electricity as energy, and the other is the spraying machine that is driven by manpower and powered by a hydraulic pump. machine, both of these spraying machines have irreparable defects

The spraying machine that relies on electricity to drive forward and spray, because it works in a relatively humid environment for a long time, it is easy to cause the circuit of the spraying machine itself to age and leak electricity, which may cause the circuit to fail during the spraying process of the inner wall of the pipeline. conditions and explosion hazards

However, for a spraying machine that sprays paint with a hydraulic spray gun, its wheels are easy to scrape off the paint that has just been sprayed on the inner wall of the pipeline, and because it is sprayed by hand, it cannot ensure that the paint is sprayed evenly, and even some paint on the inner wall of the pipeline will be overdone. Too many, insufficient paint on the inner wall of some pipelines, resulting in adverse effects such as partial corrosion or insufficient heat dissipation
