Description

Technical Field

[0001] This utility model belongs to the field of municipal construction technology, specifically relating to a robot for spraying and repairing the inner wall of a pipeline. Background Technology

[0002] Currently, municipal drainage and sewage pipelines widely use materials such as ductile iron pipes, reinforced concrete pipes, high-density polyethylene spiral wound pipes, and double-wall corrugated pipes. Pipes with a diameter of DN600 and above are easy to repair manually. However, after installation, CCTVQV inspections of the pipeline network reveal cracks, breaks, material detachment, and end damage in the inner wall anti-corrosion layer. Calculations show a high defect rate in the pipeline network. To ensure the network meets functional, safety, and economic performance requirements throughout its design lifespan, rework or the addition of inspection manholes is typically used for repair. This method is costly, time-consuming, and involves personnel entering confined spaces, posing health risks. Therefore, to repair inner wall defects in pipes with a diameter of DN500 and below, a pipeline inner wall spraying repair robot needs to be designed to address these issues. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a robot for spraying and repairing the inner wall of a pipeline. This device facilitates the repair of quality defects during construction and ensures the safety and health of personnel during operation.

[0004] To achieve the above design, the technical solution adopted by this utility model is as follows:

[0005] A pipe inner wall spraying repair robot includes a robot body with tires connected to the bottom of the body; a nozzle is connected to the front end of the body through a pipe, and a booster pump is connected to the rear end of the body through a grouting connection pipe.

[0006] Preferably, the machine body has a built-in grouting channel, which connects the nozzles at the front and rear ends and the booster pump.

[0007] Preferably, high-pressure sealing rubber is used at the connection of the grouting pipe.

[0008] Preferably, the diameter of the grouting connection pipe is 1cm to 1.2cm, which facilitates movement with the traction force of the machine body.

[0009] Preferably, the booster pump delivers the grout to the grouting connection pipe through rotational suction.

[0010] Preferably, the slurry ratio is between 0.3 and 0.7.

[0011] Preferably, multiple lights are connected to the front end of the machine body.

[0012] The beneficial effects of the above-mentioned pipe inner wall spraying and repair robot are as follows:

[0013] This device solves the problem of repairing defects in the inner wall of small-diameter pipes. It is characterized by simple operation, intuitiveness, safety, high efficiency, and guaranteed quality. It facilitates the repair of quality defects during construction and ensures the safety and health of personnel. Attached Figure Description
