Embodiment 1

[0038] like figure 1 and figure 2 as shown, figure 1 It is a structural schematic diagram of a belt conveyor control system provided by an embodiment of the present invention, figure 2 Yes figure 1 The schematic diagram of the structure of the hydraulic prop shown, the control system includes a conveyor body 10 and a controller, the conveyor body 10 is provided with a hydraulic prop 20 for supporting the conveyor body, and the hydraulic prop 20 includes an oil cylinder 21 and a telescopic rod 22 , one end of the telescopic rod 22 is movably connected with the oil cylinder 21, and the other end of the telescopic rod 22 is connected with the mine roof, wherein:

[0039] The controller is used for controlling the hydraulic pressure of the oil cylinder 21 when the first support pressure between the telescopic rod 22 and the mine roof exceeds a preset support pressure threshold.

[0040] The other end of telescopic rod 22 can be connected with mine roof by pressure sensor 23,...

Embodiment 2

[0064] Such as image 3 as shown, image 3 It is a work flow chart of a control method of a belt conveyor control system provided by an embodiment of the present invention, including:

[0065] Step S11: detecting the first support pressure between the telescopic rod and the mine roof;

[0066] Step S12: When the first support pressure exceeds a preset support pressure threshold, control the hydraulic pressure of the oil cylinder.

[0067] Specifically, a hydraulic prop is provided on the conveyor body. The hydraulic prop includes an oil cylinder and a telescopic rod. One end of the telescopic rod is movably connected to the oil cylinder, and the other end of the telescopic rod is connected to the mine roof through a pressure sensor. The pressure sensor detects the first support pressure between the telescopic rod and the mine roof in real time, and sends the detected first support pressure to the controller. When the controller receives the first support pressure sent by the...

Embodiment 3

[0078] Such as Figure 4 as shown, Figure 4 It is a work flow chart of a control method of a belt conveyor control system provided by an optional embodiment of the present invention, including:

[0079] Step S21: Detect the first support pressure between the telescopic rod and the mine roof;

[0080] Step S22: Detect the hydraulic pressure in the oil cylinder;

[0081] Step S23: Calculate the second supporting pressure of the oil cylinder on the mine roof according to the hydraulic pressure, and judge the sinking of the mine roof when the pressure difference between the first supporting pressure and the second supporting pressure exceeds the preset first pressure difference threshold;

[0082] Step S24: When the pressure difference between the first support pressure and the second support pressure exceeds the preset second differential pressure threshold and / or the number of pressurization times of the oil cylinder exceeds the preset pressure boost number threshold, it is d...

Abstract

The invention discloses a belt conveyor control system and a control method. The belt conveyor control system comprises a conveyor body and a controller, wherein the conveyor body is provided with atleast one hydraulic prop for supporting the conveyor body, and the hydraulic prop comprises an oil cylinder and a telescopic rod; the oil cylinder is movably connected to one end of the telescopic rod, and a mine roof is connected to the other end of the telescopic rod; and the controller is used for controlling the hydraulic pressure of the oil cylinder when the first supporting pressure betweenthe telescopic rod and the mine roof exceeds a preset supporting pressure threshold value. According to the belt conveyor control system and the control method, the hydraulic prop for supporting the conveyor body is arranged on the conveyor body, disassembly and assembly are convenient, the hydraulic prop can be reused, and thus the cost is reduced; and a pressure sensor is used for detect the first supporting pressure between the telescopic rod and the mine roof in real time, and the hydraulic pressure of the oil cylinder is controlled according to the first supporting pressure to realize automatic control over the hydraulic prop.

Description

technical field [0001] The invention relates to the technical field of coal mines, in particular to a belt conveyor control system and a control method. Background technique [0002] A belt conveyor is a friction driven machine that transports material in a continuous manner. It is mainly composed of frame, conveyor belt, idler roller, roller, tensioning device, transmission device and so on. It can form a material conveying process from the initial feeding point to the final unloading point on a certain conveying line. It can not only transport broken materials, but also transport finished items. [0003] In the coal mining industry, it is usually necessary to set up a belt conveyor under the mine to transport the coal from the underground to the ground. At present, the installation method of the existing belt conveyor is usually to set a cement foundation of a certain height first, then embed ground anchor bolts in the cement foundation, and finally fix the belt conveyo...
