Mixer truck and pump truck coordinative operation system, mixer truck and pump truck coordinative operation method, mixer truck and pump truck

Abstract

The invention relates to a mixer truck and pump truck coordinative operation system, a mixer truck and pump truck coordinative operation method, a mixer truck and a pump truck. The coordinative operation system comprises a target instruction input unit, a discharge control unit and a pumping control unit; the target instruction input unit is used for inputting a target instruction corresponding to discharge needed by on-site operation; the discharge control unit is used for controlling the mixer truck according to the target instruction, so that the discharge or discharge speed of the mixer truck can reach the discharge corresponding to the target instruction; and the pumping control unit is used for controlling the pump truck according to the target instruction, so that the pump output or the pumping speed of the pump truck can reach the discharge corresponding to the target instruction. The invention utilizes the target instruction input unit to input the discharge corresponding to the target instruction, the discharge control unit and the pumping control unit uniforms the respectively controlled discharge or discharge speed and pump output or pumping speed, i.e. uniforming the discharge speed and the pumping speed or uniforming the discharge and the pump output, consequently, the coordinative operation of concrete discharge and pumping is realized, and overflowing or emptying caused by the incoordination of discharge and pumping can be prevented.

Description

technical field [0001] The invention relates to a cooperative operation system for concrete in the process of unloading and pumping in the field of construction machinery, and in particular to a cooperative operation system for a mixer truck and a pump truck. In addition, the invention also relates to a concrete unloading and pumping cooperative operation method, as well as a mixer truck and a pump truck. Background technique [0002] At present, the concrete pump truck adjusts the pumping displacement to meet the concrete pouring demand during on-site construction. The larger the displacement, the larger the pumping volume, and the faster the concrete is discharged; while the mixer truck relies on manual labor at the inlet of the pump truck. Operation, adjust the unloading speed to meet the feeding demand of the pump truck hopper. In this independent operation mode, workers are often unable to carry out precise unloading control, which is easy to cause material waste and l...

AI Technical Summary

Problems solved by technology

The problem that often occurs is that the feeding speed is difficult to control, and it is always fast and slow

1) If the discharge speed is too fast, the concrete material in the hopper of the pump truck will overflow, resulting in waste; the operator often takes a shovel to shovel the overflowed concrete material back into the hopper, which consumes physical strength and increases the labor intensity of the operator

2) If the discharge speed is too slow, the concrete in the hopper will be exhausted quickly, and the pumping system of the pump truck will be sucked out, which will affect the pumping efficiency, and it will also easily cause a large vibration of the boom

[0006] At present, there is no good solution to the existing problems in the existing technology. For the speed or volume of the mixer truck unloading and the pump truck pumping material, it is impossible to ensure consistency during the entire work process, reduce overflow or suction the occurrence of the situation
