Pump truck, dredging control system and dredging control method thereof

Abstract

A pump truck dredge control system comprises: a material discharging height collection unit (101) for collecting information about a current material discharging height of a pump truck; a pumping status collection unit (102) for collecting current pumping status information of the pump truck; a processor (104) for presetting a pumping status threshold corresponding to a material discharging height, determining the current pumping status threshold based on the information about the current material discharging height of the pump truck, comparing the current pumping status information and the current pumping status threshold, determining a pipe blockage fault when the current pumping status information is larger than or equal to the current pumping status threshold, and sending an action signal to a control element (106); and the control element (106) for performing a corresponding operation based on the action signal to remove the pipe blockage fault. Further disclosed are a pump truck dredge control method and a pump truck. The pump truck dredge control system, control method, and pump truck can accurately determine a pipe blockage fault, give a warning effectively, and take an effective measure to solve a pipe blockage fault.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a pump truck dredging control system, a pump truck with the pump truck dredging control system and a pump truck dredging control method. Background technique [0002] At present, with the continuous improvement of the functions of concrete pumping equipment, it has brought great economic benefits to customers. However, in the process of concrete pumping, due to the different specifications and models of concrete, it may be difficult to pump concrete, or even blocked, causing great troubles to customers and construction units. For experienced operators, this kind of failure can be solved by switching between reverse pump and positive pump, but the judgment of pipe blockage is really unpredictable, which delays a certain amount of construction time. [0003] At present, manual experience is basically used to solve such faults, which mainly has the following shortcomings: [0...

AI Technical Summary

Problems solved by technology

[0005] 2) Adopting the method of reducing the displacement first and then switching between high and low pressure to increase the thrust of the oil cylinder can not solve this kind of situation from the root cause, which is basically similar to the automatic high and low pressure switching scheme;

[0006] 3) Only relying on the pumping pressure to judge, it is impossible to accurately locate the probability of pipe blockage, which may easily lead to misoperation;

[0007] 4) There is no pre-forecast for the concrete pumping status, and the equipment operating status information cannot be quantified;

[0008] 5) There is no corresponding warning prompt
