Abstract
A front canopy type temporary supporting suspension device for anchor pole supporting tunnel constructions. The utility model relates to a front canopy type temporary supporting suspension device for underground tunnel constructions, which mainly comprises a bearing column, a circular ring and suspension hooks. The front canopy type temporary supporting suspension device is characterized in that one end of the columnar component (i.e. the bearing column) is fixedly connected with the circular ring in a concentric way; the back parts of the handles of the suspension hooks are fixedly connected on the two sides of the bearing column along the bearing column bus direction in a planar passing through the axis of the bearing column; the surfaces on the end parts of the suspension hook handles are fixedly connected on the lower surface of the circular ring in a cooperative way; and the integral structure after the fixed connection forms the suspension device. 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 end part of the bearing column. During a working state, the suspension hooks make a front canopy hung on the lower face of the top board. The top board is then supported.
Description
Technical field
The forestope formula temporary lining that the utility model relates to a kind of underground roadway supported by bolt construction mounts puts.
Background technology
At present domestic and international sinking and drifting uses the supporting of anchor spray technique more than 90%, its temporary lining great majority adopt forestope formula support patterns; This temporary lining erecting by overhang is an affixed nut on the external surface of one section tubular element, forms erecting by overhang, and nut cooperates with the anchor pole bolt in working order; Be fixed on tubular element below the top board; Tubular element cooperates with forestope, hangs forestope below top board, realizes the effect of supporting roof.This forestope formula temporary lining erecting by overhang has following shortcoming:
1. bearing screwed cap is fixed on the external surface of tubular element, and affixed area is little, and intensity is low, can not reach the purpose of interim control top board.
2. poor stability.
3. sling point is low, and the top amount of stopping is big, and it is big to take up room.
Summary of the invention
But little in order to overcome the existing low hanging force of temporary lining intensity, the shortcoming that sling point is low.The utility model provides a kind of intensity high, and hanging force is big, and is simple in structure, makes easily temporary lining erecting by overhang easy to use.
The utility model solves the technical scheme that its technical problem adopted:
A kind of forestope formula temporary lining erecting by overhang that is used for the roadway supported by bolt construction; It comprises: bolster stake, annulus and suspension hook; It is characterized in that: at bolster stake---an end of cylindrical component is concentric affixed with an annulus, and the thickness of annulus is the height sum of the thickness and the anchor pole pallet middle part dome of anchor pole hold-down nut, and its internal diameter is greater than the diameter of pallet middle part dome; External diameter is greater than the diameter of bolster stake; Lean on an end of annulus that the screw concentric with annulus arranged at bolster stake, the degree of depth of screw is greater than the anchor pole length of appearing, and its diameter can cooperate with the anchor pole exerted bolt.Through in the plane of bolster stake axis, parallel affixed with the back of suspension hook handle along the bolster stake generatrix direction in the both sides of bolster stake, the end surface of suspension hook handle cooperates also affixed with the soffit of annulus, the overall structure formation erecting by overhang after affixed.
The present technique scheme in working order, the annulus on the bolster stake and makes the through hole at its center cooperate with the dome of anchor pole hold-down nut and anchor pole pallet up, the screw of bolster stake end cooperates with the anchor pole exerted bolt and is fixed on erecting by overhang below the top board.Suspension hook cooperates with forestope, hangs forestope below top board, realizes the effect of supporting roof through the top of stopping.
The utility model solves the technical scheme that its technical problem adopted and can also realize like this:
A kind of forestope formula temporary lining erecting by overhang that is used for the roadway supported by bolt construction; It comprises bolster stake and suspension hook, and it is characterized in that has the screw concentric with bolster stake at bolster stake one end, and the degree of depth of screw is greater than the anchor pole length of appearing; Its diameter can cooperate with the anchor pole exerted bolt; Through in the plane of bolster stake axis,, parallel affixed with the back of the suspension hook neck of hook along the bolster stake generatrix direction in the both sides of bolster stake; And making the end of suspension hook handle and the end part aligning of bolster stake, the overall structure after affixed forms erecting by overhang.
The utility model solves the technical scheme that its technical problem adopted and can also realize like this:
A kind of forestope formula temporary lining erecting by overhang that is used for the roadway supported by bolt construction; It comprises bolster stake and suspension hook, and it is characterized in that has the screw concentric with bolster stake at bolster stake one end, and the degree of depth of screw is greater than the anchor pole length of appearing; Its diameter can cooperate with the anchor pole exerted bolt; Through in the plane of bolster stake axis,, parallel affixed with the back of the suspension hook neck of hook along the bolster stake generatrix direction in the both sides of bolster stake; And the end that makes the suspension hook handle exceeds the height sum of thickness and the anchor pole pallet middle part dome of the anchor pole hold-down nut in bolster stake end, and the overall structure after affixed forms erecting by overhang.
The beneficial effect of the utility model is:
1, erecting by overhang has the rational strength structure, has 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 the suspension ring form, makes simple to operate, time saving and energy saving.
The architecture advances of 3, hanging single-beam is form of structure that can single-beam is hung and but twin beams is hung, and twin beams is hung the stability that has not only increased supporting, can also reduce by the 1/2 fixing workload of erecting by overhang.
4, because erecting by overhang has rational technical pattern, with anchor pole of the prior art fixedly erecting by overhang compare, erecting by overhang can be more near top board, reduce the top of stopping and measure, and has taken the usefull space less.
5, this erecting by overhang compared with prior art, sling point is more stable, and is more firm.
