Description

In the proposed mine hydraulic rack, in order to save water consumption, the reservoir with the latter is filled in the rack housing, and water is pumped out of it into the working space under the piston, and when the rack is transported, it is discharged back through the tap to the reservoir.

The drawing shows a vertical section miner hydraulic rack.

On a wooden stand of t, 3 bars fastened with bolts 4, a rack body 6 is installed with a bottom 5 and a lid 8 through which nopuieHb 7 passes. On the piston 7 there is a tube And, a supporting shoe 15, to which a cantilever beam is hung, protecting peeling of the roof at the slab. In the housing 6 there is a tank A, in which water is placed, mixed with a chemical solution that prevents it from freezing, and a working space B, into which water is pumped from tank A,

In terms of volume, tank A {some more working space B in order to have some water supply in case of possible leakage of it while the rack is working.

When carrying the racks, it is necessary to open the valve 18 with a special key to communicate the working space of 1Station B with tank A. As soon as the working pressure drops to atmospheric, the upper part of the rack with pistons 7 lowers under its own weight and the hanger of the piston 7 touches the covers 8; then you need to remove the shoe and the upper bars, then move the rack with crowbars, which is done by two workers. After the rack is installed, a shoe is placed in the new row and the upper bars close the valve 18, after which the water from tank A is pumped again with a pump connected to nozzle 16 through the nozzle 17 with valve to working space B to bring the stand into working position.

The subject matter of the invention.

Mining hydraulic rack, characterized in that in its housing 6 in order to save water consumption, is located reservoir A for water pumped into working space B and discharged back into the reservoir through valve 18 when carrying the rack. To the author's testimony M.D.
