Description

Technical Field

[0001] The invention relates to the technical field of concrete material conveying, and in particular to a cleaning device for a concrete material conveying pipeline. Background Art

[0002] Concrete material conveying pipeline is a common pipeline in construction and engineering. The main function of concrete conveying pipeline is to convey concrete, and to transport concrete from the mixing station to the construction site quickly and efficiently, which greatly improves the efficiency of construction. The working principle of concrete conveying pipeline is mainly to use cement slurry pump to press concrete into the conveying pipeline, and then push the concrete to the destination through high-pressure airflow or other power in the pipeline. According to the scope of use, concrete conveying pipeline is divided into two types: vehicle pump pipe and ground pump pipe. The pipe head of the pump pipe is a specially processed pipe joint, which is connected to the pipe body by welding. The connection of each pipe is connected by a pipe clamp processed by precision casting process. Concrete conveying pipeline has high compressive strength and durability, can withstand large external loads, has a long service life, is not affected by weather during construction, and improves construction efficiency.

[0003] In the prior art, after the work is completed, the inside of the conveying pipeline needs to be cleaned. There are two cleaning methods. One is to use compressed air to drive a cleaner inserted into the pipeline, and use the cleaner to clean out the concrete remaining on the pipe wall. The problem is that the compressed air-driven cleaner is unstable and there is a safety hazard. If the operation is not good, the cleaner and the concrete slurry may be sprayed out of the conveying pipe, which has the effect of an "air cannon" and affects the health of on-site personnel. The second method is to inject water into the conveying pipeline, and then start the conveying pipeline driving device to make the water mixed with concrete flow out from the pipeline outlet. The problem is that the pipeline outlet is generally arranged on the working surface, and the concrete conveying pipeline needs to be cleaned frequently (in principle, the pumping operation needs to be cleaned if it stops for more than 5 minutes). The cleaned water cannot be absorbed on the working surface, which is difficult to handle and there is a serious waste of water resources. Summary of the invention

The displacement of the connecting shell and the fixed shell body drives the airbag to displace, thereby realizing the cleaning of the internal concrete slurry.
