Embodiment Construction

[0026] Such as figure 1 The electrical control system of the thin coal seam electric traction shearer shown, the core component is the controller, which may include the main controller and the expansion controller, which are connected through the CAN bus. Each controller is also connected with corresponding operation buttons, temperature sensors, current sensors and control relays.

[0027] The controller is respectively connected with the local display operation device and the remote host computer through the CAN bus, the bus conversion module and the RS232 serial port bus.

[0028] This system uses the explosion-proof button to control the start and stop of the cutting motor. By automatically starting at staggered time, the superimposed peak current of each motor is greatly reduced, which prolongs the life of the motor and protects the power grid at the same time.

[0029] This system monitors the temperature rise of each engine in real time through each motor temperature s...

Abstract

The invention provides an electric control system of a thin-seam electric traction coal mining machine, relating to the field of engineering machinery. The electric control system comprises a temperature sensor, a current sensor, operation buttons, a relay, a controller, a display operation device and the like. The electric control system can be used for completing various control to the coal mining machine; a human-machine interface supplies a conversion environment to an operator with the coal mining machine; and the current working state and the current working parameters of the coal mining machine can be learned through the human-machine interface, the states of various working points are monitored in real time, and simultaneously, the operator the operator can also set the control parameters of the coal mining machine through the human-machine interface. By utilization of the electric control system, the automation level of the coal mining machine can be increased, the working efficiency is high, and stronger reliability is equipped. Meanwhile, energy saving, consumption reduction and environment pollution reduction can be realized by using electric power.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to an electric control system for a thin coal seam electric traction shearer. Background technique [0002] Coal shearer is divided into four types: sawing type, planing type, drilling type and milling type. It is a coal mining machine that breaks coal with a rotating working mechanism and loads it into a conveyor or other transportation equipment. It is a mechanical, It is a large and complex system integrating electrical and hydraulic pressure, and the working environment is harsh. If there is a failure, it will lead to the interruption of the entire coal mining work, resulting in huge economic losses. With the development of the coal industry, the shearer has more and more functions, and its own structure and composition are more and more complex, so the reasons for the failure are also complicated. [0003] The reserves of thin coal seams (thickness less than 1.3 meters) i...
