Synchronous control method for pushing oil cylinders of slope mining transporting unit

Abstract

The invention belongs to the technical field of open pit coal mine equipment control, and particularly relates to a synchronous control method for pushing oil cylinders of a slope mining transportingunit. The synchronous control method comprises the following steps that S100, a main oil cylinder and a slave oil cylinder are determined; S200, a parameter value of a control curve is determined; S300, a curve is fitted to obtain a curve expression; and S400, the current speed Vs of the slave oil cylinder is obtained according to the obtained output variable y. The synchronous control method forthe pushing oil cylinders of the slope mining transporting unit acts on a specific transporting unit driving device of slope equipment, synchronous control over the oil cylinders on the two sides is achieved by obtaining the specific curve through multiple times of demonstration in combination with slope mining working condition requirements and existing conditions, the error of mechanical designis made up, the complexity of hydraulic control is reduced, the slope mining cost is saved, and the curve parameters are adjustable; and further adjustment can be conducted according to the working conditions and the like to achieve the expected effect, and flexibility and operability are achieved.

Description

technical field [0001] The invention belongs to the technical field of equipment control in open-pit coal mines, in particular to a synchronous control method for pushing oil cylinders of side mining transport units. Background technique [0002] At present, my country's national economy is in a period of rapid development, and the demand for energy has been further increasing. As one of the major energy sources in my country, coal's main position is still unshakable. In recent years, with the increase of my country's energy consumption and the introduction of environmental governance policies, the requirements for coal utilization and mining rates have increased year by year. Due to the particularity of mining and the imperfection of related technologies in open-pit coal mines, most of the accumulated coal in the thin coal seam of the side is abandoned in China. In view of this, a new type of side mining complete set of equipment has been developed in China. The equipment ...

Problems solved by technology

Due to various factors such as the difference in the hydraulic circuit and the error of its own mechanical design, the phenomenon of out-of-synchronization of the push cylinders on both sides is caused, and the stroke error of the push cylinders on both sides will directly cause the transport unit to deviate from the track, and the fuselage will be skewed to damage the equipment, directly causing Paralysis of side mining

There is currently no effective and suitable synchronous control method for the left and right side push cylinders of the transport unit to achieve stable walking of the transport unit
