Abstract
The utility model discloses a special bottom adjusting device for a thin coal seam bracket. A bottom adjusting beam hinge lug base and a bottom adjusting jack hinge lug base are arranged at the outer side of a thin coal seam bracket base outer main rib; one end of a bottom adjusting beam is hinged to the bottom adjusting beam hinge lug base; one end of a bottom adjusting jack is hinged to the bottom adjusting jack hinge lug base; and the other end of the bottom adjusting beam and the other end of the bottom adjusting jack are hinged to each other. The extension and shrinkage of the bottom adjusting beam are realized by changing the triangular shape through adjusting the edge length of the triangular bottom adjusting jack by using the principle of triangle stability. The special bottom adjusting device for the thin coal seam bracket is simple in structure and easy in arrangement, and is suitable for the restraint and slip adjustment of the thin coal seam bracket.
Description
Technical field
The utility model relates to a kind of coal-mine hydraulic support, relates in particular to a kind of Bracket in Thin Coal Seam special bottom and adjusts device.
Background technology
China's girdle (1.3 meters of thickness are following) resource distribution is very extensive, and reserves are abundant, but girdle occurrence condition is generally more complicated, and large multiple seam has larger seam inclination, much in 25 degree, and general inclination angle is 15-50 degree.High inclination-angle support in use, especially moves in frame process, be prone to wag the tail, phenomenon even glides.
In medium-thickness seam (1.3 to 3.5 meters) hydraulic support, all adopt lateral thruster and the end to adjust device, act on two positions up and down of support, be the effective mode of maturation that suppresses and regulate support to glide.
In prior art, the end of medium-thickness seam (1.3 to 3.5 meters) hydraulic support, adjusts device to have the end to adjust very heavy top and bottom to adjust two kinds of modes of crossbeam:
As shown in Figure 1 a, 1 b, for beam structure is adjusted at the end; As shown in Figure 2, for jack structure is adjusted at the end.
But for hydraulic support for low coal seam, due to the restriction in space, base cabinet is thinner, the embedded end, cannot be installed and adjusts jack.At present, the adjusting that high inclination-angle Bracket in Thin Coal Seam is wagged the tail, glided, mainly relies on lateral thruster, and device is adjusted at the end of Bracket in Thin Coal Seam, has not yet to see application.
Utility model content
The purpose of this utility model is to provide a kind of Bracket in Thin Coal Seam special bottom simple in structure, easy layout and adjusts device.
The purpose of this utility model is achieved through the following technical solutions:
Bracket in Thin Coal Seam special bottom of the present utility model is adjusted device, outside Bracket in Thin Coal Seam base, at the bottom of the arranged outside of main muscle, adjust the hinged ear seat of beam and the end to adjust the hinged ear seat of jack, the end, adjusts one end of beam and the described end to adjust the hinged ear seat of beam hinged, the end, adjusts one end of jack and the described end to adjust the hinged ear seat of jack hinged, and the described end adjusts the other end of beam and the described end to adjust the other end of jack to be hinged.
The technical scheme being provided by above-mentioned the utility model can be found out, the Bracket in Thin Coal Seam special bottom that the utility model embodiment provides is adjusted device, owing to adopting the end to adjust beam and the end to adjust jack to be articulated with respectively the outer main muscle of base outside, the end, adjusts the other end of jack and the end to adjust the beam other end hinged, utilize the principle of triangle stability, by adjusting the length of very heavy top margin at the bottom of adjusting triangle shape, change leg-of-mutton shape, realize the end and adjust stretching place and shrinking of beam, simple in structure, easily arrange, be applicable to Bracket in Thin Coal Seam inhibition and glide regulate.

Detailed description of the invention
To be described in further detail the utility model embodiment below.
Bracket in Thin Coal Seam special bottom of the present utility model is adjusted device, its preferably detailed description of the invention be:
Outside Bracket in Thin Coal Seam base, at the bottom of the arranged outside of main muscle, adjust the hinged ear seat of beam and the end to adjust the hinged ear seat of jack, the end, adjusts one end of beam and the described end to adjust the hinged ear seat of beam hinged, the end, adjusts one end of jack and the described end to adjust the hinged ear seat of jack hinged, and the described end adjusts the other end of beam and the described end to adjust the other end of jack to be hinged.
The described end, adjusts one end that beam and the described end adjust jack to be hinged to be positioned at a side of the tune hinged ear seat of beam of the described end and the hinged ear seat of end tune jack, or adjusts the hinged ear seat of beam and the end to adjust between the hinged ear seat of jack at the described end.
The described end, adjusts the hinged ear seat of beam and the end to adjust the hinged ear seat of jack and the Bracket in Thin Coal Seam base main muscle structure that is welded as a whole outward.
The described end, adjusts the hinged ear seat of beam and the end to adjust the outer main muscle of the hinged ear seat of jack and Bracket in Thin Coal Seam base to be connected by bearing pin or bolt.
The described end, adjusts beam to be changed a social system by shaped steel or form with steel plate butt welding.
