Abstract

The invention relates to the field of underground mining of coal deposits and can be used to hold and move downhole conveyors in the lavas of flat and inclined seams. The goal is to ensure the work on the sloped fall layers. The actuator drive 2 downhole conveyor includes hydraulic racks (GS) 1,3, located on both sides of the conveyor. The bases of HS 1 are pivotally connected to the drive 2 of the conveyor (K). The bases of the HS 3 are pivotally connected to the ends of the support beam 4. In the latter, a longitudinal groove 5 is made, by means of which the beam 4 vertically located on the axis of the roller 6 is connected to the 2 K drive. The axis of the roller 6 is fixed on the 2 K drive. , 3 on each side of K are pivotally interconnected by hydraulic jacks (DG) 9 installed at an angle to the longitudinal axis K. As the drive 2 K moves along the lava roller 6 moves along the groove 5 of the beam 4, which rotates relative to the drive 2 K around the hinge at the base of HS 3. Simultaneously with the ba lacquer 4 unfolds and DG 8. After sampling the expansions of DG 9, they bulge HS 1, remove the thrust from HS 3, and fold DG 9 and move GS 3 along the lava. 4 il.

Description

one

The invention relates to underground mining of coal deposits and can be used to retain and move downhole conveyors in the lavas of gentle and inclined seams.

The purpose of the invention is to ensure the work on the formations of an inclined fall.

Downhole drive actuator

fan contains hydroracks 1, the bases of which are pivotally connected to the drive 2 of the conveyor; hydrorails 3, the bases of which are pivotally connected to the ends of the support beam 4, having a longitudinal groove 5 with a roller 6 located in it, the axis 7 of which is rigidly attached to the bottom of the drive 2 of the conveyor, hydraulic jacks 8 sliders pivotally connected to the conveyor drive 2 and the base of the hydraulic post 3 located on the downstream side of the conveyor, the hydraulic jacks 9, the pivotally connecting bases of the hydropeeders 1 and 3 and angled to the longitudinal axis of the conveyor Era, overlap 10 and 11, merging in pairs across the conveyor belt 1 and 3.

The conveyor drive is moved as follows.

The strut is removed from the hydraulic rails 1 and the working fluid is supplied to the piston cavities of the hydraulic jacks 8 and they are moved apart. Due to the fact that the hydraulics 3 at this time are under thrust, ensuring that the beam 4 is stationary, the conveyor drive 2 moves to the bottom, while its weight is transmitted through the roller 6 to the walls of the longitudinal groove 5 of the support beam 4. .

After moving the conveyor drive 2 to the step of digging the hydraulic post 1, the conveyor drive 2 is prevented from creeping up when the thrust is removed from the hydraulic post 3 and moved by folding the hydraulic jacks 8.

In the process of conventional shifting of the drive 2 of the conveyor and hydraulic legs 3 to the bottom of the hydraulic jacks 9 are not involved in the work and their piston and rod cavities are switched to the drain. However, thanks to their diagonal arrangement

The hydraulic jack 9, located on the intake side of the conveyor, can also be used when moving the drive 2 to the face. Hydrojacks 9 are also used when shifting the spacer legs 3 in the event of a change in the direction of developmental development. In this case, by appropriately inserting the hydraulic jacks 9 onto the expansion or folding, the support beam 4 is turned on the roller 6 in one direction or the other.

After the conveyor drive 2 is disconnected from the pan, the roller connecting the end of the beam 4 to the base of the hydraulic post 3 is taken out, the run of the hydraulic posts 1 is released, and the hydraulic jacks 9 move the conveyor drive 2 along the lava. In this case, 3 hydraulic rasperty. As the conveyor drive 2 moves along the lava, the roller 6 moves along the groove 5 of the beam 4, and the latter moves the conveyor drive 2 around the hinge at the base of the hydraulic column 3. At the same time with the beam 4, the hydraulic cylinders 8 unfold as well. thrust from hydraulic rails 3 and make folding of hydraulic jacks 9, and with it the shifting of hydraulic rails 3. along the lava. In this case, the roller 6 moves in the opposite direction. In the opposite direction, the beam 4 and hydraulic jacks 8, which do not participate in the force mode, also turn, and their piston and rod cavities are connected to the drain. After the drive of the conveyor 2 is moved along the lava by an amount equal to the length of the pan, the end of the beam 4 is again connected to the base of the hydrorack 3 located on the downhole side of the conveyor.

The initial position of the downhole end of the beam 4 relative to the bottom of the downhole hydraulic post 3 so that after moving the conveyor drive 2 along the lava to place the connecting roller in place, is ensured by the appropriate switching on of the hydraulic jacks 8 and 9. These operations are carried out in the absence of a thrust in the hydroresistant 3 while the hydraulics 1 are under thrust. Formula l and 3 rev.
