This coal mine tunnel struts support, be equipped with the variable -spacing adjustment roof beam, accessible plus -minus variable -spacing adjustment roof beam, control the interval size between the support, in order to satisfy different colliery builder's yards, the support adopts H type high -tensile structural steel, the anti transverse strength of support both sides has been increased, can effectively keep out the side -thrust that the support received, saved materials, additionally, W type ripple crossbeam is adopted respectively with the support of back timber to the connection of support upper end circular arc department, W type back timber bearing diagonal, the rock produces the support in the time of can effectively keeping out the construction, the impact force of back timber.
Description
Technical field
The utility model relates to Roadway Support Technology field, concrete a kind of colliery tunnel support support.
Background technology
In the mine of modern fully-mechanized mining, especially in stope of coal mines, along with the continuous increase of mining depth, geological condition is complicated all the more, not only Underground pressure increases, and the bump having no omen even appears in part mining area, causes serious casualties and property loss.
The passage of stope of coal mines all can be provided with some roadway supports, but the support of current roadway support often adopts rectangle or cylindrical structure, and both torsional resistances are not good, and compare waste material, not easily carry, back timber is often directly connected with support, spacing between support is remained unchanged, there is certain limitation, specific construction plant can only be used for, in addition, during construction, rock can be subject to impact force, causes support circular arc place and back timber to be subject to impact force, there is potential safety hazard.
Utility model content
The purpose of this utility model is to provide a kind of colliery tunnel support support, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme: a kind of colliery tunnel support support, comprise support, spacing regulates beam and back timber, the upper end of described support is provided with boss, described boss is provided with locating piece, described support connects spacing by the boss of upper end and regulates beam, described spacing regulates the boss of beam one end to be provided with groove, the boss of the other end is provided with locating piece, locating piece on described bracket bosses is arranged in the groove on spacing adjustment beam boss, described spacing regulates the upper end of beam to connect back timber, described support and spacing regulate beam and spacing to regulate the junction of beam and back timber all to be locked by lock ring, the upper end of described support is connected by W type ripple crossbeam, described back timber connects W type ripple crossbeam by W type back timber bearing diagonal symmetry, described W type ripple beam surface evenly has adjustment hole.
Preferably, described support adopts H type high-tensile structural steel.
Preferably, described back timber and spacing regulate beam to be U-shaped structure, and the structure at back timber two ends and spacing regulate the structure at beam two ends identical.
Preferably, nut check is passed through at described lock ring two ends.
Preferably, the end both sides of described support are fixed by bolt and right-angle installation rack and right angle base plate.
Compared with prior art, the beneficial effects of the utility model are: this colliery tunnel support support, be provided with spacing and regulate beam, beam is regulated by plus-minus spacing, control the spacing size between support, to meet different construction plants, colliery, support adopts H type high-tensile structural steel, add the anti-buckling strength of support both sides, effectively can keep out the side-thrust that support is subject to, improve supporting capacity, in addition, the connection at pedestal upper end circular arc place and the support of back timber adopt W type ripple crossbeam respectively, W type back timber bearing diagonal, when effectively can keep out construction, rock produces support, the impact force of back timber.
