Description
Technical Field
The invention relates to the technical field of concrete equipment, in particular to a concrete pumping device and concrete pumping equipment.
Background
After the concrete pumping equipment works, the conveying pipeline, the distributing pipe valve (also called an S pipe valve) and related parts which are in contact with the concrete are required to be cleaned, so that the influence on the usability caused by the coagulation and solidification of the concrete on the surfaces of the parts which are in contact with the concrete is eliminated.
The current cleaning method completely adopts manual operation, a cleaning component such as a cleaning ball or a cleaning column (the cleaning ball and the cleaning column are made of sponge, rubber or a sponge and rubber composite structure, have certain overall compressibility, such as the diameter of 260mm in a free state, and can be placed into a pipeline with the diameter of 100 mm) is placed in a conveying pipeline, and the cleaning ball or the cleaning column is pushed to move forwards by water pressure or air pressure so as to push concrete in the conveying pipeline out of the conveying pipeline, thereby achieving the aim of cleaning the concrete conveying pipeline.
Taking a pump truck of a concrete pumping device as an example, see fig. 1 and 2, the path through which concrete passes during pumping operation is as follows: the unset concrete enters the hopper 1, is sucked into the delivery cylinder 3 by the pumping mechanism and pumped out through the distribution pipe valve 2, the delivery pipe 8, the final outlet pipe 82 of the delivery pipe, and reaches the casting working surface.
Currently, cleaning protocols generally have the following:
method one (see fig. 1 and 2): the cleaning ball or the cleaning plunger is manually moved into the outlet pipe 82 at the tail end of the concrete conveying pipe, the atmospheric pressure at the outlet end is caused by the reverse pump (negative pressure is formed in the pipeline) to push the cleaning ball or the cleaning plunger in the pipeline to move forward towards the feed inlet (conveying cylinder) until the pump is stopped at the elbow 81 of the conveying pipeline 8, which is connected with the distributing pipe valve 2, the pipe clamp on the elbow 81 is manually disassembled, the elbow 81 is rotated to take out the cleaning ball or the cleaning plunger therein, and the residual concrete in the elbow is washed by water until the residual concrete is cleaned. The cleaning path is as follows: the concrete delivery pipe ends outlet pipe 82 to elbow 81.
Method two (see fig. 1 and 2): manually disassembling a pipe clamp on the elbow pipe 81 connected with the distribution pipe valve 2, rotating the elbow pipe 81, removing part of concrete in the elbow pipe 81 (removing a cleaning ball or a cleaning column which can be put in), feeding the cleaning ball or the cleaning plunger into the elbow pipe 81, then pumping by a click, pushing the cleaning ball or the cleaning column in a pipeline to advance towards the outlet end of the pipeline by pumping water, and discharging the concrete in the pipeline from the outlet pipe at the tail end of the concrete conveying pipeline. The cleaning path is as follows: elbow 81→the outlet pipe 82 at the extreme end of the concrete delivery pipe.
The existing cleaning mode of the concrete pumping equipment needs to disassemble the pipeline (namely, disassemble the bent pipe 81 between the distributing pipe valve 2 and the conveying pipeline), so that the cleaning efficiency is low, and time and labor are wasted.
