Description

This invention relates to the loading of trolleys in underground loading stations of coal mines.

A hydraulic station is known, including pusher drives and overlapping of the intercarriage space. Aeolotics of the sensors for monitoring the loading and position of the trolleys and the pumping station provide automatic loading and exchange of trolleys 1J. .

The operation of this device showed that, despite the high parameters of the pump station and the pusher drive, the carrying capacity of the loading point remains low. This is explained as follows.

Research has shown that the total load time of the trolley is divided into three periods:

The 1 st period is the time when the primary cone of coal was formed in the trolley when the pusher drive does not work and the trolley is stationary. This time is

Dimensionally 33% of the total load cycle time;

2period - loading time of the middle part of the trolley, when the trolley moves at a constant speed with a sufficient traffic flow (about 40% of the cycle time);

3period - the loading time of the end part of the trolley, when the loading of the trolley (positioning the coal at an angle of repose) should be done as the speed of its movement increases, since by the end of the loading the volume of the trolley decreases.

per unit of its length.

However, the hydraulic pusher does not have the ability to increase the speed above the nominal, which leads to the fact that the winding capacity is loading-.

The 0th point remains lower than possible, since the pusher operates at a nominal speed only in the 3rd period, and in the 2nd period it works with pauses.

The purpose of the present invention is to increase the capacity of the load item.

The goal is achieved by: THAT the drive of the pusher is connected to the hydro - bGK1sumuMy1Gb {5b1y cheroze throttle and spool, one of the cavities of which is connected to the pressure head of the spool: the load of the carriage load sensor, and the other unit with the pressure piece of the wagon, and the other, with a face piece of the wagon, the headset, and the wr-wdp unit. and a koay position sensor located at a distance from the first drive, which is the length and height of the trolley body

After the formulation is set to its original position for loading, for example, by electro-electrose, to which the pressure position corresponds. sensors 20 and 21 and 5, the down position of sensors 22, the pump station 1 is turned on. The working fluid from the pump 3 through the safety valve is simultaneously supplied to the branch pipes -, 7, 8, 11, 12, 13.

0 Since the sensor 22 is omitted, the working fluid through the spool 13 enters the right (according to the scheme) end cavity of the spool 7, which moves to the left (according to the scheme), because its other cavity is connected to the drain through the spool 11 (sensor 20 : reap).

After moving the spool 7 to the left, the working fluid enters the drive

0 6 override 23, which occupies the working position a. At the same time, the working fluid enters the spool 9 of the sensor, which is lowered, since there is no main coal in the trolley, and through it in

the end cavity of the spool 8, which, moving, directs the working fluid through the check valve 17 to the hydraulic accumulator 14. The system is ready for operation, after which the conveyor line is turned on. Line coal enters the trolley. During the loading of the primary cone, the working fluid is directed to the accumulator 14. When the cone angle deflects. sensor 19, the end cavity of the spool

i 8 is connected to the discharge through the spool 9 and the working fluid through the moved spool 8 enters the drive of the pusher 5. Medium hour loading Tj: 7th Cycle occurs when moving NI to its pusher; at the command of the sensor 19. The body of the next car rejects the sensor 22, changing the position of the valve 13, but the change in the scheme does not occur, since the valve

It is rejected by coal) enters the right (according to the scheme) end cavity of the spool 15, which moves to the left (according to the scheme), since its cavity is connected to the drain through the spool 11. Moving the spool 15 provides connection of the battery 14 through the throttle 16 with the pusher drive 5. The latter moves the trolley with increasing speed. The end of the loading of the truck is accompanied by a change in the position of the spool 11 of the 2 O sensor, which causes the transfer of the dolotnik 7 to the right (according to the scheme), the supply of working fluid to the left strip of the actuator 6, the overlap and shunting position b, the connection of the end cavity of the spool 8 with the drain, regardless of the position of the spool 9 of the sensor 19, turning on the pusher drive through the gold 8, the composition is moved to set the next trolley to its original position, which is monitored by the sensor 22, which responds, returns from its position to the starting position, after which the cycle is repeated. Thus, the system ensures the accumulation of working fluid in the battery at the time of just the trolleys and transfers it to the desired configuration (when loading the end part of the trolley), which improves the use of parameters of the pump station and leads to an increase in the loading capacity of the loading point. ; Claims of the system of loading control of a carriage that includes drives of the pusher and torsion of bodies of the intercarriage space, spools of drive control, sensors of loading and position of carriages, hydroaccumulator, throttle, check valves, pumping station, which, in order to increase the throughput of the loading point the drive of the pusher is connected to the hydroaccumulator via a choke and a spool, one of the cavities of which is connected to the pressure cavity of the spool of the first along the loading of the sensor the carriage is in communication with the pressure cavity of the loading sensor spools and the second position sensor located at a distance from the first one, determined by the length and height of the trolley body and the angle of repose of the loading material, and through the sensor spool loading, or sequentially through the spools of the load sensor and the second along the sensor position of the trolley.
