Anti-pipe-blocking detection device, spraying device, pipeline material recycling method and pipeline cleaning method

Abstract

The invention provides an anti-pipe-blocking detection device, a spraying device, a pipeline material recycling method and a pipeline cleaning method. The anti-pipe-blocking detection device comprisesa valve body, an adjusting assembly and a proximity switch; the valve body is provided with a passage for connecting a to-be-detected pipeline and a branch communicating with the passage; the adjusting assembly is assembled in the branch, and the adjusting assembly comprises a piston matched with the branch, an elastic body acting on the piston and an end cover connected to the end of the branchin the mode of being capable of moving relative to the branch; and the proximity switch is assembled on the valve body and is arranged corresponding to the piston. The anti-pipe-blocking detection device is simple in structure, a related hydraulic system does not need to be additionally arranged, the pressure in the to-be-detected pipeline can be continuously adjusted, the pressure relief can be conducted on the pipeline in time when pipe blockage occurs, and pipe explosion accidents are avoided; according to the spraying device, residual materials in the pipeline can be collected back to a material barrel, and materials are saved; and the pipeline can be cleaned, the damage to devices due to material solidification is avoided, and therefore the service life is prolonged.

Description

technical field [0001] The application relates to the technical field of pipeline spraying construction, in particular to an anti-blocking pipe detection device, a spraying equipment, and a method for recovering and cleaning pipeline materials. Background technique [0002] At present, more and more construction robots are used to complete construction operations such as exterior wall spraying, interior wall spraying or concrete wet spraying. Since the operation of construction robots is generally an automated process and unattended, the normal operation of its various operations is based on various detection methods. When spraying, if the spraying material is real stone paint, concrete, etc., because it contains more solid particles, and the material is viscous, has poor fluidity and is easy to solidify, construction robots often block pipes during actual spraying.

AI Technical Summary

Problems solved by technology

When spraying, if the spraying material is real stone paint, concrete, etc., because it contains more solid particles, and the material is viscous, has poor fluidity and is easy to solidify, construction robots often block pipes during actual spraying. Case

However, materials such as real stone paint and concrete are not like water, gas, oil and other materials that can be detected by sensors, and there are few pressure sensors suitable for detecting real stone paint, concrete and other materials

Moreover, when the construction robot sprays, it sprays automatically. When a pipe is blocked, if it cannot be sensed in time, the spraying will not be in place.

In addition, the sprayed materials generally contain glue. If the blocked pipe is not treated in time, the material may be damaged after solidification, and the pipeline may be scrapped; pipe burst accident
