Problems solved by technology

[0004] Due to the long-term flow of concrete in the delivery pipeline, it is inevitable that some concrete will remain on the pipe wall. If the delivery pipeline and the pipeline of the switching device are not cleaned in time, the delivery efficiency of the concrete will be seriously affected.
In the above-mentioned automatic switching device for delivery pipes, since the hig

Abstract

The invention discloses a conveying pipe switching device of a material conveying system, comprising a first pipeline and a second pipeline and also comprising a fixed frame and a moving frame. The outer side of the fixed frame is fixedly connected with a discharging pipe and a feeding pipe, the first pipeline and the second pipeline are fixedly connected with the moving frame, one side of the fixed frame is provided with a first leading-in hole and a second leading-in hole, the other side of the fixed frame is correspondingly provided with a first leading-out hole and a second leading-out hole; and the moving frame is connected with a power part and switches between a first working position and a second working position relative to the fixed frame by the power device. Accordingly, the pipelines can be cleaned without dismounting the conveying pipe switching device from the system pipeline, and the pipelines can be conveniently cleaned in time. The invention also discloses a material conveying system comprising the conveying pipe switching device.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to a conveying pipe switching device for a material conveying system. The present invention also relates to a material conveying system comprising the above conveying pipe switching device. Background technique [0002] Concrete pumping system is a very common material delivery system. In the construction process, when a drag pump pumps concrete for two buildings or pumps concrete for different areas of the same building, it is necessary to switch the concrete pipeline. At the same time, in order to ensure construction safety in large-scale important projects, it is also necessary to switch pipelines between multiple towed pumps. When switching pipelines, it can be realized by manually disassembling the elbow or manually disassembling the pipeline switching device, but both of these methods need to stop the pump and empty the concrete in the pipeline, and the disassembly and a...
