Abstract
A front canopy type temporary supporting device for anchor pole supporting tunnel constructions. The utility model relates to a front canopy type temporary supporting device for underground tunnel constructions, which mainly comprises a bearing member, suspension members and front canopies. The temporary supporting device is characterized in that the lower part of the rectangular planar plate (i.e. the bearing member) and the suspension members are fixedly connected to form a suspension device; the suspension members include a U-shaped suspension member, a groove-shaped suspension member, a planar plate type round suspension member and a planar plate type hook-shaped suspension member. The suspension device and an anchor pole bolt are fixed on the lower face of a top board in a cooperative way through a screw hole on the bearing member. The suspension device then makes the front canopy hung on the lower face of the top board through the suspension members. The top board is then supported. The front canopies include a U-shaped front canopy, a groove-shaped front canopy and a round front canopy which respectively cooperate with the corresponding suspension member to form the temporary supporting device.

The utility model solves the technical scheme that its technical problem adopted and can also realize like this:
A kind of forestope formula temporary support device that is used for the roadway supported by bolt construction; It mainly comprises bearing carrier; Hang member and forestope; It is characterized in that: erecting by overhang is at vertical affixed flute profile suspension ring below the rectangle plane plate of bearing carrier, and the integrated member after affixed forms one section rectangular tubular parts.On the soffit of the middle part of rectangle plane plate, there is a rectangular elements affixed with it along channel member deepening direction; The cylinder hole of diameter greater than anchor pole hold-down nut diameter arranged at the center of rectangle plane plate, a screw concentric with cylinder hole is arranged in the bottom of cylinder hole.Cylinder hole cooperates with the anchor pole hold-down nut in working order, and screw cooperates with the anchor pole bolt, is fixed on erecting by overhang below the top board, and the flute profile suspension ring cooperate with the flute profile forestope, hangs forestope below top board, and support action is realized to top board in the top through stopping.
This is suitable for the technical scheme realization like this that novel its technical problem of solution is adopted:
A kind of forestope formula temporary support device that is used for the roadway supported by bolt construction; It mainly comprises bearing carrier; Hang member; And forestope, it is characterized in that: erecting by overhang be below the rectangle plane plate of bearing carrier vertical affixed one with the wide U-shaped suspension ring of rectangle plane plate, have the rectangle fin in the soffit center of rectangle plane plate; In the center of rectangle plane plate upper surface the cylinder hole of diameter greater than anchor pole hold-down nut diameter arranged downwards, a screw concentric with cylinder hole is arranged in the bottom of cylinder hole.Cylinder hole cooperates with the anchor pole hold-down nut in working order, and screw cooperates with the anchor pole bolt, is fixed on erecting by overhang below the top board, and the U-shaped suspension ring cooperate with the U-shaped forestope, hangs forestope below top board, and support action is realized to top board in the top through stopping.
The beneficial effect of the utility model is:
One, erecting by overhang
1, have the rational strength structure, increased the intensity of supporting roof, can more effective control roof accident, reduce personal injury and economic loss.
2, erecting by overhang develops into the suspension hook form by single suspension ring form, makes more convenient operation, and is time saving and energy saving.
3, be improved to dicyclo to the monocycle form of hanging and hang form, not only increased the stability of supporting, can also reduce by the 1/2 fixing workload of erecting by overhang.
4, because erecting by overhang has rational technical pattern, compare with anchor pole erecting by overhang of the prior art, erecting by overhang can reduce the top amount of stopping more near top board, has taken the usefull space less.
5, this erecting by overhang compared with prior art, sling point is more stable, and is more firm.
Two, forestope
Use the U-shaped forestope, the flute profile forestope can make forestope in working order more near top board, reduces the top amount of stopping.
