Utility model content
The purpose of this utility model there is provided a kind of coal mine tunnel suspension device; contractibility is large; supporting capacity is strong; bending resistance and twisting resistance strong; be under pressure after avoiding section to increase flexural deformation; supporting effect is good; the stable of roadway surrounding rock body can be safeguarded well; improve the supporting intensity to tunnel side direction and base plate; solve pucking because tunnel side pressure causes and tunnel bottom width to narrow phenomenon; improve tunnel integer support intensity, solid and reliable, decrease the roof accident in tunnel and the safety of protection constructor.
The technical solution adopted in the utility model is as follows:
A kind of coal mine tunnel suspension device, comprise arched roof, reinforced shed and arch of the anti-end, described arched roof is arranged at above reinforced shed, arch of the anti-end is arranged at below reinforced shed, described arched roof comprises arched girder and symmetrically arranged pillar, the top of described pillar is provided with groove, the two ends of arched girder are located at groove, arched girder is connected with pillar upper-end bent, the lower end of described pillar tilts laterally, described reinforced shed comprises crossbeam and symmetrically arranged canopy leg, welded by U-shaped holder between crossbeam with canopy leg, described crossbeam is connected to form by two U29 type clamps by two U29 shaped steel, described canopy leg comprises telescopic mast and hollow sleeve, described telescopic mast and hollow sleeve nested encryptions, junction is provided with fastening bolt, arch of the described anti-end is arranged on below roadway floor, packed layer is provided with between arch of the anti-end and roadway floor, described packed layer is spoil.
Described arched girder and junction, pillar upper end embed rubber mass backing plate.Embed rubber mass backing plate, make arched roof have certain contractibility, between arched girder and pillar, gapless forms continuous supporting, makes arched girder can not because of the flexural deformation that is under pressure.
The radian of described pillar upper-end bent is 30 degree, and the angle of inclination of lower rod end is 10 degree.
The bottom of described canopy leg is provided with backing plate.
Described crossbeam is provided with limited block.Limited block plays and increases the effect that resistance is spacing, prevent crossbeam continuation from shrinking.
Compared with the prior art, the beneficial effects of the utility model are as follows:
(1) coal mine tunnel suspension device of the present utility model; by arranging arched roof, reinforced shed and arch of the anti-end; described arched roof is arranged at above reinforced shed; arch of the anti-end is arranged at below reinforced shed, supporting capacity is strengthened, improves tunnel integer support intensity; the stable of roadway surrounding rock body can be safeguarded well; solve pucking because tunnel side pressure causes and tunnel bottom width to narrow phenomenon, solid and reliable, decrease the roof accident in tunnel and the safety of protection constructor.
(2) coal mine tunnel suspension device of the present utility model, described arched roof comprises arched girder and symmetrically arranged pillar, the top of described pillar is provided with groove, the two ends of arched girder are located at groove, arrange groove by the top at pillar, and the two ends of arched girder are located at groove, groove makes the top of pillar not only play longitudinal supporting role to arched girder, and also there is supporting role to the transverse direction of arched girder, thus make integrated support more stable, improve supporting effect; Arched girder is connected with pillar upper-end bent, the pressure at top, tunnel is transferred to the pressure of pillar to ground, tunnel, and the lower end of pillar tilts laterally, effectively the pressure of tunnel side direction is converted into the pressure on ground, tunnel, solve pucking because tunnel side pressure causes and tunnel bottom width to narrow phenomenon, improve supporting intensity; Simultaneously embed rubber mass backing plate at arched girder and junction, pillar upper end, make arched roof have certain contractibility, gapless formation continuous supporting between arched girder and pillar, make arched girder can not because of the flexural deformation that is under pressure.
(3) coal mine tunnel suspension device of the present utility model, described reinforced shed comprises crossbeam and symmetrically arranged canopy leg, welded by U-shaped holder between crossbeam with canopy leg, described crossbeam is connected to form by two U29 type clamps by two U29 shaped steel, canopy leg comprises telescopic mast and hollow sleeve, telescopic mast and hollow sleeve nested encryptions, junction is provided with fastening bolt, roadway deformation can be prevented, after being subject to ore deposit pressure, crossbeam and canopy leg have contractibility, can not because of the flexural deformation that is under pressure, supporting effect is good, make its applicable large section roadway supporting, the old U29 type steel shed adopting down-hole to reclaim processes, accomplish the recycling of material, arch of the described anti-end is arranged on below roadway floor, and between arch of the anti-end and roadway floor, be provided with packed layer, described packed layer is spoil, effectively increases the supporting to base plate, prevents pucking phenomenon, strengthen tunnel integer support intensity.
