Pump truck, dredging control system and dredging control method thereof

Abstract

The invention provides a dredging control system for a pump truck, which comprises a discharging height collecting unit, a pumping state collecting unit, a processor and a control element, wherein the discharging height collecting unit is used for collecting the present discharging height information of the pump truck; the pumping state collecting unit is used for collecting the present pumping state information of the pump truck; a pumping state threshold value corresponding to the discharging height is preset in the processor; the processor is used for confirming the present pumping state threshold value according to the present discharging height information of the pump truck, comparing the present pumping state information with the present pumping state threshold value, confirming a pipe plugging fault if the present pumping state information is more than or equal to the present pumping state threshold value, and sending an actuating signal to the control element; and the control element executes the corresponding operation according to the actuating signal so as to eliminate the pipe plugging fault. According to the technical scheme provided by the invention, the pipe plugging fault can be accurately judged and effectively warned, and the effective measures are taken for solving the pipe plugging fault. The invention also provides the pump truck and a dredging control method for the pump truck.

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...

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
