(54) MOUNTING MECHANISM

I

The invention relates to equipment for penetrating inclined and horizontal mine workings by drilling and blasting, and is intended for use in the coal and mining industries.

Known installation for excavation of mine workings, which includes bucket loading machines, scraper loader, boring machines, crepe layer, located on the full frame, suspended through the unit to the lifting winch 1.

The required pressure forces are provided by hydraulic jacks associated with the installation frame. With a sufficiently large inclination angle and the mass of the complex, which is about 25 tons, the necessary pressure forces are provided.

When flattening out the inclined development, the component mass of the complex turns out to be so small that it does not provide the effort needed to insert the bucket. So, with a tilt angle of 4 °, the component mass of the complex will be less than 2 tons instead of the required 6-8.

As the blasted rock mass is unloaded, the complex is lowered by a lifting winch. At small angles of inclination and clogged rail tracks, the complex can be jammed and the rope lapped.

Closest to the invention to the technical essence and the achieved result is the feed mechanism of the mining machine, which includes a transverse beam, on which grippers are installed to interact with the guide beam and a feed jack, hinged on the transverse beam.

The disadvantages of this mechanism: the complexity of the design and the lack of pressure

10 force mining machine in the workings with a low angle.

The aim of the invention is to simplify the design and increase the pressure of the mining machine in workings with a small angle.

15 tilt.

The goal is achieved by the fact that the hydraulic cylinder of the thrust is installed between the grips across the guide rail, which has a suspension rope block.

FIG. 1 shows a hearth machine;

20 in FIG. 2 - mining machine feed mechanism.

On the sheathed frame 1 of the complex there is a loading machine 2, a loader 3, a drilling rig 4, crepe layers 5 and transverse beams 6 located across the rail track. Transverse beam 6 is equipped with rail grippers 7, driven by a hydraulic cylinder 8 thrust. On the transverse beam 6 is placed the pulley 9, through which the rope hoist winch thrown. A hydraulic jack 10 of the feed connects the beam with the frame 1 of the complex.

When drilling, the frame 1 of the complex is installed at the required distance from the bottom with the help of the feed jack 10, the transverse beam 6 with the grippers 7 is fixed to the rails.

In bucket loaders, the pressure force of which is provided by special hydraulic jacks, the cross bar is fastened — beam 6 is gripped by hooks 7 by the rails. During the descent of the complex, its mixing drains and is already sealed by the hydraulic jack 10 forcibly. When the jack stem 10 is extended to its full length, the transverse beam 6 is pulled by the same jack with the lifting winch turned on.

In case a more efficient loading machine with side grip is used on the complex, the proposed mechanism provides the receiving table

Machines necessary pressure forces, regardless of the angle of inclination and without the use of any additional feed, their devices.
