(54) CONTROL DEVICE OF POSITION COMPLEX

I

The invention relates to mining and can be used in control systems of hydroficated plow complexes.

A device for controlling a plow complex with a support and a conveyor is known, which includes a low-pressure conveyor movement line, a high-pressure movement support pipe, a support pipe, a drain line, conveyor movement hydraulic jacks, and a control distributor (}.

The disadvantage of the known device is that it does not allow the front support jacks of the lining section to be pulled forward at the same time while folding the hydraulic jacks of the conveyor and pressing the plow to the bottom.

The purpose of the invention is to increase the workmanship by reducing the resistance in frontal movement of the lining, while simultaneously ensuring the optimal value of firmly pressing the conveyor with the plane to the face.

The goal is achieved by the fact that the device is equipped with a controllable

a check valve with a supra-valve, subvalvular and control cavities, through which the piston cavities of the conveyor inner-hydraulic jacks are connected to a drain line, and the supra-valve and subvalvate cavities of the hydraulically controlled reverse valve are connected respectively to the pressure and slug lines of the headboard by the headboard. the distributor either from drain, or from the pressure head - -. 10 liters of travel firmly.

The drawing shows a hydraulic diagram of the plow complex control device.

The device contains a pressure head 1 and a drain 2 low pressure line of movement of the conveyor 3, a pressure head 4 and drain 5 high pressure line of the support of the lining 6, a hydraulic valve 7 of the movement of the conveyor 3, hydraulic cable jacks 6, control valve 9 and one directionally controlled return a valve 10 with an over-valve 11, a double-valve 12, and a control 13 cavities.

At -JTOM of the downstream line 4, the working fluid is supplied to the piston cavity of the hydraulic jacks 8. After the hydraulic piston rod 1 and the hydraulic jacks 7 are moved forward 1 and below the conveyor 3, the control valve 8 switches to the extreme right working position. The pressurized fluid enters simultaneously in lines 4 and 5 of the high pressure of movement of the lining 6. All rods of hydraulic jacks 8 are pulled out and all hydraulic jacks 7 are forcedly collapsed. At the same time, hydraulic control valve 13 receives pressure from drain line 5, which is hydraulically controlled the check valve 10 is opened and the lines 1 and 2 are interconnected, in connection with which the resistance of the hydraulic jacks 7 is reduced and the optimum pressure force of the conveyor 3 and the jet are ensured ha to slaughter.

The proposed device allows increasing the service life of the high-pressure hoses of the hydraulic jacks of the conveyor movement, reducing the energy consumption of the pumping stations of the complex and increasing the performance of individual operations of the production cycle, since the folding process of the conveyor hydraulic jacks is performed simultaneously throughout the laae.
