Concrete pump and pumping control device and pumping control method thereof

Abstract

The invention discloses a concrete pump and a pumping control device and a pumping control method thereof. The pumping control device is used for pumping control of an engine of the concrete pump, a main oil pump and a pumping system, and comprises a plurality of sensors, a controller, a quick response unit and an energy-saving working unit, wherein the plurality of sensors are used for acquiring revolving speed, displacement, pumping times and pressure signals; the controller is used for judging whether the pumping working condition is stable, if so, performing revolving speed and displacement control on the output of the energy-saving working unit, otherwise, performing revolving speed and displacement control on the output of the quick response unit; the quick response unit is used for outputting revolving speed signals and displacement signals capable of allowing the pumping system to quickly respond the pumping working condition requirement; and the energy-saving working unit is used for calculating the power required for meeting the pumping working condition requirement and calculating and outputting the economic revolving speed and the corresponding displacement of the main oil pump according to an optimal fuel consumption curve. By using the device and the method, the energy consumption is greatly saved on the premise of meeting the construction requirement, and the service life of the pumping system of a pump truck can be prolonged.

Description

technical field [0001] The invention relates to a concrete pump, in particular to a pumping control device of the concrete pump, a pumping control method of the concrete pump and a concrete pump with the pumping control device. Background technique [0002] In the prior art, concrete pumps (also called concrete delivery pumps) with diesel engines as power units include concrete pump trucks, trailer pumps, and vehicle-mounted pumps. These concrete pumps use the output power of the diesel engine to transmit energy to the pumping hydraulic cylinder through the constant power variable pump connected to the diesel engine and the hydraulic system connected to it, and pump the concrete to the required position through the reciprocating movement of the piston of the hydraulic cylinder, that is, During the pumping process, there is an energy transfer between "engine-pump" and "pump-hydraulic system". [0003] In the prior art, in order to make the output power and torque of the engi...
