Abstract
The utility model discloses an anti rock burst tunnel hydraulic support, include: the roof beam body and stand, the roof beam body is provided with the stand including entablature, bottom end rail, back timber between entablature, the bottom end rail, and the back timber lies in the stand top and has the flat needling of forging, and the upper portion pin joint of back timber has the entablature, is connected with a pneumatic cylinder of propping up and regain the entablature between back timber and the entablature. Anti side pressure resilient means has all been settled to the lower part in the two parallel stands, fine reduction the shock effect of tunnel side pressure to the support, the needling on the base of bottom is for forging flat needling, the column cap has adopted the crew cut formula, has strengthened the shock resistance of stand and structure. The device has been solved region of high stress tunnel intersect and has been strutted the problem.
Description
Technical field:
This utility model relates to apparatus field, mine, presses alley hydraulic support particularly to a kind of shock resistance.
Background technology:
Early stage, heading all adopted railway steel supporting, and along with the deepening of mine, this support pattern can not meet the needs of mine pressure, the tunnel production constraining mine in bad repair.After 98 years, coal road have employed anchor net and adds U-shaped canopy composite support mode at net section 12m2Normal big without demonstrating supporting intensity in geological structure coal road below, that rate in bad repair reduces advantage.But at particularly fork, the roadway junction tunnel place, place that geological structural belt region of stress concentration or belt conveyer head section are bigger, easily occur roadway deformation speed in bump region fast, in bad repair seriously have a strong impact on ventilation, current and produce.
It addition, process tunnel work in bad repair easily cause bump, especially belt conveyer head tunnel infall, it is desirable to drift section is relatively big, equipment volume is relatively big, and after support compressive deformation, working space is little, and personal safety is constituted very big danger.
Utility model content:
Press alley hydraulic support to the shock resistance that the technical problems to be solved in the utility model is to provide a kind of flexible dismounting, antirust and resistance to corrosion is strong.
A kind of shock resistance ground pressure alley hydraulic support, including: beam body and column, beam body includes entablature, sill, back timber, it is provided with column between upper and lower crossbeam, back timber is positioned at column top and has the flat needling of forging, the top of back timber is articulated with entablature, is connected to the hydraulic cylinder supporting and regaining entablature between back timber and entablature.Two parallel posts middle and lower parts are all mounted with lateral pressure resistant elastic device, and well decreasing the tunnel side pressure impact on support affects, and the needling in bottom base is for forging flat needling, and stigma have employed cab over type, enhances the impact resistance of column and structural member.
Can conveniently dismantle between each big parts of described support and bracket hydraulic parts Antirust corrosion-resistant ability is strong.
This utility model one shock resistance ground pressure alley hydraulic support innovation is in that:
(1) hydraulic support is provided with the relief valve of especially big flow, in order to timely release under bump, it is to avoid damage column；
(2) cylinder body and stigma do not adopt the bulb type of general expression, change cab over type into, the needling of corresponding back timber and base is the flat needling of forging, enhance the impact resistance of column and structural member, for overcoming the tunnel side pressure impact to support, it is provided with lateral pressure resistant elastic device, for preventing the Floor Heave in Roadway caused under bump effect, under support, is provided with the sill of anti-pucking；
(3) can conveniently dismantle between each big parts of support and bracket hydraulic parts Antirust corrosion-resistant ability is strong.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of a kind of anti bumping gateway hydraulic powered support of this utility model.
Fig. 2 is the side view of a kind of anti bumping gateway hydraulic powered support.
Detailed description of the invention
As Fig. 1 and Fig. 2 presses alley hydraulic support structure chart for a kind of shock resistance, including: beam body and column 6, beam body includes entablature 1, sill 2 prevents the Floor Heave in Roadway, the back timber 3 that cause under bump effect, it is provided with column 6 between entablature 1, sill 2, back timber 3 is positioned at column 6 top and has the flat needling of forging, the top of back timber 3 is articulated with entablature 1, is connected to the hydraulic cylinder supporting and regaining entablature between back timber 3 and entablature 1.Two parallel posts 6 middle and lower parts are all mounted with lateral pressure resistant elastic device 5, and well decreasing the tunnel side pressure impact on support affects, and the needling in bottom base 4 is for forging flat needling, and stigma have employed cab over type, enhances the impact resistance of column and structural member；Essential distinction is there is no with conventional stent using method in using this stent procedures, including: rise, decline, advance, move frame, only difference is that described structure construction features.
The above; it is only detailed description of the invention of the present utility model; but protection domain of the present utility model is not limited thereto; any those of ordinary skill in the art are in the technical scope disclosed by this utility model; the change that can readily occur in or replacement, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with claims protection defined.
Claims (3)
