Description
Technical Field
The invention relates to the field of mining equipment, in particular to an anti-toppling device for a coal machine, which is used during the production of a depression angle of an underground coal face of a coal mine.
Background
The mining of the fully mechanized working face with a large inclination angle is a technical problem in the coal mining industry, an effective mining method is always explored at home and abroad for many years, but the coal seam is endowed with special conditions, and a plurality of difficulties are brought to safe, efficient and mechanized mining. The anti-falling device of the large-inclination-angle working surface corollary equipment is always in an exploration phase. The gravity received by the coal machine on the working face is decomposed into a normal component perpendicular to the upper edge of the coal machine and a tangential component parallel to the working face. The normal component force of the tangential component force is beneficial to stabilizing the coal machine, and the tangential component force pushes the coal machine to slide and roll downwards along the coal bed, so that the stability of the coal machine is not beneficial. The larger the inclination angle is, the more the tangential force borne by the coal machine is increased, the normal force is reduced, the more prominent the rolling inclination problem of the coal machine is, the gear of the walking part is separated from the rack rail, the stress of the walking gear is concentrated, the damage is increased, and the production is influenced because the walking gear cannot walk in serious conditions.
Disclosure of Invention
The invention aims to provide an anti-tipping device of a coal machine, which is beneficial to the stability of the coal machine.
The technical scheme of the invention is as follows:
the utility model provides a coal machine anti-overturning device, includes base, flexible roof beam and removal piston shoes, its characterized in that, the base includes the front with flexible roof beam contact and the reverse side with coal machine contact, the base bends to the reverse side, the base adopts the pin junction with flexible roof beam, flexible roof beam adopts the pin junction with removal piston shoes, be equipped with the jack in the flexible roof beam, the flexible end and the removal piston shoes of jack are connected.
Furthermore, flexible roof beam includes the shell, the shell upper end is connected with the base through bearing frame and round pin axle, the shell endotheca has flexible shell, shell and jack main part fixed connection, flexible shell is connected with the flexible end of jack.
Furthermore, the movable sliding shoe comprises a bottom plate, and two sides of the bottom plate are tilted upwards.
Furthermore, limiting clamps are arranged on two sides of the telescopic beam, and reinforcing rib plates are arranged on the outer sides of the limiting clamps.
The invention has the beneficial effects that:
1) the problem of the coal machine fuselage to the coal wall slope when big dip angle is pitched is solved, the normal contact of walking gear with the rack bar has been guaranteed, provides the guarantee for safe normal production. The damage to the cable when the rack is pushed to slide and the abrasion of the cable is obviously reduced.
2) The damage to the walking gear and the rack bar caused by the inclination of the coal machine is solved, the maintenance workload of the rack bar and the walking gear is effectively reduced, and the economic advantage is obvious.
3) The anti-dumping device of the coal machine provides power for adjusting the telescopic beam through the emulsification pump station, the telescopic beam does not need to be operated repeatedly for a coal wall with better integrity, and the anti-dumping device of the coal machine has no dependence on the power and is simple to operate.
4) The anti-dumping device for the coal machine has the advantages of simple structure, easy processing and higher popularization value.

Detailed Description
The invention is further described with reference to the following description and embodiments in conjunction with the accompanying drawings.
The utility model provides a coal machine anti-overturning device, includes base 1, flexible roof beam 2 and removes piston shoes 3, its characterized in that, base 1 include with the front of flexible roof beam contact and with the reverse side of coal machine contact, base 1 bends to the reverse side, base 1 adopts the pin junction with flexible roof beam 2, flexible roof beam 2 adopts the pin junction with removing piston shoes 3, be equipped with the jack in the flexible roof beam 2, the flexible end of jack is connected with removing piston shoes 3.
Further, flexible roof beam 2 includes shell 21, shell 21 upper end is connected with base 1 through bearing frame and round pin axle, shell 21 endotheca has flexible shell 22, shell 21 and jack main part fixed connection, flexible shell 22 is connected with the flexible end of jack.
Further, the movable sliding shoe 3 comprises a bottom plate 4, and two sides of the bottom plate are tilted upwards.
Furthermore, limiting clamps 5 are arranged on two sides of the telescopic beam, and reinforcing rib plates 6 are arranged on the outer sides of the limiting clamps 5.
During the use, two sets of coal machine anti-overturning devices are through round pin axle or welding on the coal machine, and the effect that supports the coal machine can be realized to the control jack is flexible, and the coal machine fuselage during operation is parallel with the scraper conveyor medium plate all the time, guarantees coal machine walking gear and the normal contact of rack rail strip, has guaranteed normal production, has reduced the damage to rack rail strip and walking gear, has reduced maintenance work volume.
