Embodiment Construction

[0023] An embodiment of the present invention will be further described below in conjunction with accompanying drawing:

[0024] The cooling control system of the shearer motor of the present invention is mainly composed of three parts: an airborne water pipe retractable control device 2 , a ground water pipe protection control device 4 and a water pipe groove 5 . The on-board water pipe retractable control device 2 is installed on the coal shearer 1, the water pipe 3 drawn from the water pipe tank 5 is connected to the water-carrying pipe retractable control device 2, and the ground water pipe protection control device 4 has two sets, which are respectively installed in the coal mining machine Both sides of the machine walking track are coordinated and controlled with the airborne water pipe retractable control device 2 through communication, such as figure 1 shown.

[0025] The airborne water pipe retractable control device 2 is composed of a controller 6 , a motor driver 7...

Abstract

Belonging to coal mine motor protection methods and devices, the invention relates to a coal mining machine motor cooling control system and method. The system consists of an onboard water pipe contraction-release control device, a ground water pipe protection control device and a water pipe groove. Specifically, the onboard water pipe contraction-release control device is composed of a controller, a motor driver, a reel water pipe motor, a water pipe reel and a communication circuit. The ground water pipe protection control device is composed of a communication circuit, a microprocessor, a motor driver, a shutter motor, a reel and a protection shutter. The system and the method provided by the invention can provide cooling water to the coal mining machine conveniently and safely, prevent coal cutting motor overheating, and ensure electric safety and efficient mining.

Description

technical field [0001] The invention relates to a control system and method, in particular to a cooling control system and method suitable for coal mine shearer motors. technical background [0002] The high-power motor of the coal mining machine for cutting coal is prone to heat when it works for a long time, causing insulation aging and shortening the service life. Therefore, it is necessary to adopt a water-cooling method to dissipate heat for the motor. The water supply of the coal mining machine is usually the water pump leading out the water pipe to the coal mining machine for water supply. There are currently two methods of laying water pipes from the mobile substation to the coal shearer. One is to hang the water pipe on the pulley for water supply through the roof pulley; the other is to lay the water pipe through the bottom groove of the scraper conveyor. water pipe. But no matter which way, the water pipe will rub against the moving situation of the coal shearer...
