Description

Step-type cleaning machine for variable-size pumping concrete conveying pipeline Technical Field The invention relates to the technical field of pipeline cleaning, in particular to a variable-size step-by-step type cleaning machine for a pumping concrete conveying pipeline. Background The pumping concrete is to transport and pour concrete mixture along the conveying pipe by a concrete pump or a pump truck. The concrete mixture transportation method is an effective concrete mixture transportation mode, is fast in speed and low in labor force, is particularly suitable for transportation and pouring of large-volume concrete and high-rise building concrete, and is generally used for transporting pumping concrete at present by adopting an assembled steel pipe, and the interior of a transportation pipeline is required to be cleaned after the work is finished. The high-rise pumping concrete pipeline cleaning is usually performed in a water washing and air washing or water-air combined washing mode, the air washing is to drive a cleaner plugged into the pipeline by using compressed air, the cleaner is used for cleaning out concrete remained on the pipeline wall, but the compressed air is used for driving the cleaner to be unstable, potential safety hazards exist, the cleaner is not easy to operate, the cleaner is connected with a concrete slurry spraying conveying pipe, an air cannon effect is achieved, the health of field personnel is affected, water is injected into the conveying pipeline, a conveying pipeline driving device is started to enable water mixed with concrete to flow out from a pipeline outlet, the pipeline outlet is generally arranged on a working face, the concrete conveying pipeline needs to be cleaned frequently (in principle, the pumping operation is stopped for more than 5 minutes, the cleaned out water cannot be consumed on the working face, the processing is difficult, and water resource waste is caused.
