SU279545A1 - HYDROPHYTED FASTENER FOR DEVELOPMENT OF INCLINED AND TILTED LAYERS - Google Patents

Description

The invention relates to the field of underground mining of coal seams oblique and steep falls, namely, the fastening of the working faces.

Hydroficated roof supports are known for developing inclined and steep seams, including sections of the same type with bases, hydraulics and ceilings, inclined hydraulics, and lower and upper base beams, consisting of pivotally connected sections and interconnected telescopes. However, these supports are not stable during movement, because the position of each section at the end of its turn must adjust visually relative to the uncovered adjacent sections. This leads to errors when installing sections during operation, which, as a result, makes it impossible to restore each section of the lining.

The return of the inclined sections to the normal position is necessary to lead only from the extreme upper or lower sections, which is a time consuming operation that requires a lot of time.

The purpose of the present invention is to ensure the stability of the heel during movement.

The upper base beam is equipped with a follower device, made of a spool and the levers connected with it, which are connected to the beam section and interact with the hydroresistant section of the harness.

FIG. 1 shows the proposed lining, view from the bottom; in fig. 2 - the same, top view; in fig. 3 shows the node A in FIG. one.

The support is made up of individual sections, each of which has a base /, 2-uphill hydraulic posts to 3. Sections with non-movement hydraulic jacks 4 and restoring hydraulic jacks 5 are connected to the lower base beam 6. The hydraulic jack 7 is connected to the telescopic stand 8. The lower and upper base beams 6 and 9 combine the lining sections into separate groups. Telescopic post 8 connects both base beams to each other. The inclined W stand is installed in the center of each section group.

The section of the upper beam 9 is provided with a follower device consisting of the valve 11 of the control of the hydraulic cylinder 7 and the levers 12. The levers are pivotally connected to the section of the upper beam and interact with the hydroresistant 2. The switching of the slide is realized by means of the springs 13.

with it and attached to it with the help of telescopic struts of the upper beam section; the cavities of the jacks 5 and 7 are connected to the drain, and the inclined hydroresistance 10 is connected to the pressure line. The teleconsole rack and the sections of the upper beam are in a normal position relative to the lower beam.

Subject invention

Aggregated roll for development of sloping and steep seams, including

sections of the same type with axes, hydraulics and overlaps, inclined hydroresistances, lower and upper base beams, consisting of hinged sections and interconnected telescopic links, which differ from TQU in order to ensure the stability of the support during shifting , upper to each section of the tilt is connected by means of a hydrojack with a telescopic stand, and the section of the upper base beam is equipped with a follower device, made of a spool and associated levers hinged to the section of the beam in Interaction of a gndrostoykoy support frame.
