Abstract
A telescopic strut capable of preventing U-shaped steel from deforming belongs to the technical field of underground equipment for a coal mine, and relates to a telescopic support device that is used for preventing U-shaped steel from deforming and is used underground in the coal mine. The telescopic strut comprises the technical scheme as follows: the telescopic strut comprises U-shaped steel cross beams, U-shaped steel clips, Pi-shaped beams and individual hydraulic props, wherein every two U-shaped steel cross beams are connected to form a telescopic cross beam, the two ends of which are fixed at the upper parts of the two ends of each Pi-shaped beam; in addition, the top ends of the individual hydraulic props are fixed at the bottoms of grooves formed in the two ends of the Pi-shaped beams, and the bases of the individual hydraulic props are fixed on a laneway bottom plate. The telescopic strut has the advantages as follows: the telescopic strut is used as a deformation-resisting auxiliary device for the laneway steel erecting shed support, can adapt to different cross sections of a laneway, can bear four pressures from the laneway in the upper direction, the lower direction, the left direction and the right direction at the same time, can prevent the steel erecting shed support from deforming to the utmost extent, and can also lead working personnel to visually observe an existential threat through the pressure bearing states of the telescopic cross beam and the hydraulic props so as to develop a treatment solution in time to eliminate disasters and dangers in the bud of accidents.
Description
Technical field
The invention belongs to equipment technology field under the coal mine, relate to the scalability U shaped steel anti-deformation bracing or strutting arrangement that uses under a kind of coal mine.
Background technology
Roof accident is one of the major casualty in colliery, and it is that the coal seam is destroyed support apparatus and the landslide accident of generation by various pressure influences, and safety in production and worker's life security have been caused serious threat.At present, U shaped steel shed shoring is used in the down-hole supporting more.Traditional U shaped steel shed shoring often causes deformation of timbering because of Tunnel Pressure is excessive; When influencing workmanship safety is also caused certain influence; Being out of shape serious steelframe canopy supporting loses enabling capabilities and causes the landslide of roof fall even large tracts of land; Make the disaster enlarged areas, the safety of down-hole worker and whole mine in serious threat.
Summary of the invention
The objective of the invention is: this device prevents to make steelframe canopy supporting gross distortion cause unpredictalbe danger owing to Tunnel Pressure is excessive in the roadway support process.
Technical scheme of the present invention is: this device is made up of four U shaped steel crossbeams, two cover U shaped steel clamps, two π type beams and four hydraulic props; Wherein per two U shaped steel crossbeams connect to form a scalable crossbeam from beginning to end through U shaped steel clamp; The two ends of scalable crossbeam are fixed on top, π type beam two ends; π type beam slot opening is downward, and the top of hydraulic prop is fixed on π type beam two ends bottom portion of groove, and the base of hydraulic prop is fixed on the roadway floor.
Beneficial effect of the present invention: this device is as the anti-deformation servicing unit of tunnel steelframe canopy supporting; Can adapt to the tunnel different section; Bear the tunnel pressure in four orientation up and down simultaneously; Prevent steelframe canopy supporting distortion to greatest extent, also make the staff observe the threat of existence so that in time formulate processing scheme, disaster is threatened the bud of eliminating in accident through the artesian condition of flexible crossbeam and hydraulic prop.
Description of drawings
Accompanying drawing 1 is a structural representation of the present invention.
Accompanying drawing 2 is A of the present invention-A cross-sectional view.
Accompanying drawing 3 is user mode sketch mapes of the present invention.
The specific embodiment
This device is made up of four U shaped steel crossbeams 1, two cover U shaped steel clamps 2, two π type beams 3 and four hydraulic props 4, and wherein per two U shaped steel crossbeams 1 connect to form a scalable crossbeam from beginning to end through U shaped steel clamp 2.Scalable crossbeam is provided with entire length according to the concrete size of tunnel steelframe canopy supporting 5 before use flexibly, and its entire length shortens when bearing the left and right sides, tunnel pressure in the use and surpassing certain numerical value, and the numerical value of shortening is intuitively shown by self scale.The two ends of scalable crossbeam are fixed on top, π type beam 3 two ends, and π type beam 3 slot openings are downward, and the top of hydraulic prop 4 is fixed on π type beam 3 two ends bottom portion of groove, and the base of hydraulic prop 4 is fixed on the roadway floor 6.Hydraulic prop 4 bears downforce on the tunnel in using, and this compression value shows through self scale value.
This device is as the anti-deformation servicing unit of tunnel steelframe canopy supporting 5; Can adapt to the tunnel different section; Bear the tunnel pressure in four orientation up and down simultaneously; Prevent steelframe canopy supporting 5 distortion to greatest extent, also make the staff see the threat of existence intuitively so that in time formulate processing scheme, disaster is threatened the bud of eliminating in accident through the artesian condition of flexible crossbeam and hydraulic prop.
