Abstract
The invention discloses a combined-connected mining transverse H-shaped steel bracket for supporting a mining roadway. The mining transverse H-shaped steel bracket mainly comprises bracket legs, stop pieces, support plates and base plates, wherein the bracket legs are arranged at the two ends of a bracket beam of the mining transverse H-shaped steel bracket; the stop pieces are arranged on the lower parts of the two ends of the bracket beam; the support plates are arranged at the top ends of the bracket legs; the base plates are arranged at the bottoms of the bracket legs. The mining transverse H-shaped steel bracket is structurally characterized in that a limiting block is arranged on the upper part of each of the two ends of the bracket beam; a rectangular hole is formed in the upper end of each bracket leg; straight connecting plates in the rectangular holes are connected with U-shaped connecting plates on the bracket beam. The mining transverse H-shaped steel bracket has the advantages of simple structure, high safety, convenience in mounting and dismounting and practicability.
Description
Technical field
The present invention relates to a kind of mining tunnel suspension device, specifically the mine I-beam bracket of composite joint for a kind of mining tunnel supporting, belongs to field of mechanical technique.
Background technology
H steel ladder shape support for mine use is the conventional a kind of support pattern in colliery, the rack beams two ends of this support are each fixes a rack leg, a block of each welding below rack beams two ends, prevent that rack leg from moving to the inside, rack leg top is welded with U-shaped supporting plate, prevent that rack beams from swinging, rack leg bottom welding has had the backing plate of stabilization.Because the rack making of this structure is simple, convenient, and be easy to installation and removal, in stope of coal mines roadway support, application is very extensive.But this support likely can loss of stability in following several situations, thereby cause the generation of roof fall or casualty accident, cause mine safety accidents.The one, in the time that press on tunnel top, side pressure is excessive or pucking is serious, easily cause the crooked and beam leg dislocation of rack beams rollover, rack leg, uncoupling, then there is support and be caving.The 2nd, when Tunnel Pressure is large, when support middle part reinforcing with hydraulic prop, rack beams and rack leg be dislocation and uncoupling easily, causes rack leg to topple over and support out-of-control phenomenon.The 3rd, in the time that surge occurs in tunnel, the block that rack leg likely can knock suddenly in rack beams is swung in the middle of tunnel, thereby causes casualties or fall of ground accident.
Summary of the invention
Task of the present invention is to provide a kind of simple in structure, safe, and installation and removal is convenient, the mine I-beam bracket of practical composite joint.
For realizing above-mentioned task, technical scheme solution of the present invention is:
A kind of mine I-beam bracket of composite joint, the rack leg mainly respectively being arranged by the rack beams two ends of H steel ladder shape support for mine use, each block arranging below rack beams two ends, the backing plate that the supporting plate that rack leg top arranges and rack leg bottom arrange forms, the mine I-beam bracket of described composite joint respectively arranges a limited block on rack beams two ends, upper end at each rack leg arranges rectangular opening, and the direct-connected plate arranging in rectangular opening is connected with the U-shaped connecting plate arranging in rack beams.
The present invention has the following advantages:
One, simple in structure, installation and removal is convenient, practicality.
Two, improved the resistance to overturning of support, made support under larger top pressure, side pressure and pucking effect, the phenomenons such as the upset of beam body, skew, beam leg uncoupling can not occur, supporting effect is more reliable;
Three, in the time reinforcing support is middle with hydraulic prop, the change in location of rack beams can not cause that beam leg uncoupling separates and roof fall accident;
Four,, in the time there is bump in tunnel, rack beams and rack leg are also difficult for dislocation and uncoupling;
Five, when the block in rack beams is come off by surge vibration, direct-connected plate is connected with bolt with the U-shaped connecting plate of back-off in rack beams through the rectangular opening on rack leg.The connection and the slip cushioning effect that have played card cable, rack leg still can keep the holding state to rack beams, is caving and roof fall phenomenon and can there is not support.

The specific embodiment
As shown in Figure 1, a kind of mine I-beam bracket of composite joint, mainly respectively weld a rack leg 2 by rack beams 1 two ends of H steel ladder shape support for mine use, a block 3 of each welding below rack beams 1 two ends, the supporting plate 4 of rack leg 2 top welding and the backing plate 5 of rack leg 2 bottom weldings form, a limited block 10 of each welding on rack beams 1 two ends, make rectangular opening 9 in the upper end of each rack leg 2, direct-connected plate 7 is connected with the U-shaped connecting plate 6 use bolts 8 of back-off in rack beams 1 through rectangular opening 9.
Claims (1)
1. the mine I-beam bracket of a composite joint, comprise the each rack leg arranging in rack beams two ends of H steel ladder shape support for mine use, each block arranging below rack beams two ends, the backing plate that the supporting plate that rack leg top arranges and rack leg bottom arrange, it is characterized in that: a limited block is respectively set on rack beams two ends, upper end at each rack leg arranges rectangular opening, and direct-connected plate is arranged in rectangular opening and is connected with the U-shaped connecting plate arranging in rack beams.
