Intelligent control system of double speed gearbox of dredge pump and control method thereof

Abstract

The invention discloses an intelligent control system of a double speed gearbox of a dredge pump and a control method thereof. The control system comprises an input shaft rotating speed sensor, an output shaft rotating speed sensor, a gear shifting state detecting element, an electrical control element of a gear shifting mechanism and a main controller, wherein a signal input end of the main controller is electrically connected with the input shaft rotating speed sensor, the output shaft rotating speed sensor, an electrical control system of a clutch of the dredge pump and the gear shifting state detecting element; and a signal output end of the main controller is electrically connected with a control signal input end of the electrical control element of the gear shifting mechanism. The control method comprises the following steps: after the main controller receives a gear shifting command input by a user, the main controller judges whether the rotating speeds of a power input shaft and a power output shaft are zero and whether the joint state of the clutch of the drudge pump is in a disconnecting state; and if yes, the electrical control element of the gear shifting mechanism is used for controlling the gear shifting mechanism to shift the gear. The invention realizes the gear shifting control on the double speed gearbox of the dredge pump and meets the requirements of a trailing suction dredge for different rotating speeds under different working conditions such as dredging and mud blowing.

Description

technical field [0001] The invention relates to gear box gear shift control technology, in particular to an intelligent control system and a control method for a two-speed gear box of a dredging dredger dredge pump. Background technique [0002] A trailing suction dredger is an underwater excavating machine. It sucks mud through the rake heads placed on both sides or stern of the hull, and works in a way of sucking mud while sailing. Strong wind and waves, large digging depth, etc., suitable for operations in coastal ports, wide rivers and ship anchorages. [0003] The dredge pump gearbox is an important part of the dredger. After being decelerated, the power of the prime mover can be efficiently and stably transmitted to the dredge pump system. Traditional mud pump gearboxes are all in the form of a single input shaft and single output shaft, and the mud pump can only work at one speed. At the present stage, according to the needs of actual engineering, trailing suction d...
