Abstract
The utility model relates to a support technical field is used in the colliery, specifically is a telescoping shoring column for coal mine. It is including relative downside canopy leg that sets up and high side canopy leg, be connected with the back timber between downside canopy leg and the high side canopy leg, high side canopy leg is connected with the footing board, each junction all fixed with the card cable, downside canopy leg and back timber, back timber be the arc structure with the high link that inclines the canopy leg, all the other positions are linear structure, back timber, downside canopy leg and the cross section of high side canopy leg be the U type. The utility model discloses simple structure, simple installation adapt to the coal seam of different angles, supporting intensity is high, ensures the production safety, the tunnel high -usage has reduced the broken rock engineering volume during the tunnelling, and the tunnelling progress is fast.
Description
Technical field
The utility model relates to support technology field, colliery, specifically a kind of colliery telescoping shoring column.
Background technology
In recent years, along with the intensification of coal mining depth, the pressure that mine is born more comes more serious, and mine roadway support difficulty strengthens.Huge pressure not only destroys roadway supporting system and surrounding rock structure, also threatens the life security of underground work personnel.
At present, usually trapezoidal canopy or U-shaped canopy supporting is adopted in mine laneway.Adopt trapezoidal canopy supporting, supporting intensity is low, and roadway deformation is comparatively large, and driving progress is slow, and potential safety hazard is large, is unfavorable for safety in production; The supporting intensity of U-shaped canopy is high, but adopts the tunnel utilization rate of U-shaped canopy supporting low, and broken rock amount is large.
Summary of the invention
In order to overcome defect of the prior art, the utility model provides a kind of colliery telescoping shoring column.The utility model structure is simple, simple installation, adapts to the coal seam of different angles; Supporting intensity is high, guarantees production safety; Tunnel utilization rate is high, the broken rock engineering quantity during decreasing driving, and driving progress is fast.
The utility model is achieved through the following technical solutions: a kind of colliery scalability frame, comprise the downside canopy leg and high side canopy leg that are oppositely arranged, back timber is connected with between described downside canopy leg and high side canopy leg, described high side canopy leg is connected with footing piece, and described each junction is all fixed with card cable; The link of described downside canopy leg and back timber, back timber and high side canopy leg is arcuate structure, all the other positions linearly structure; The cross section of described back timber, downside canopy leg and high side canopy leg is U-shaped.
Preferably, be triangle bottom described footing piece.
The beneficial effects of the utility model are: the link of downside canopy leg and back timber, back timber and high side canopy leg is arcuate structure, by the coal seam regulating connecting length can adapt to different angles, adopt card cable to fix, be preferably triangle bottom footing piece, improve supporting intensity.
The utility model structure is simple, simple installation, adapts to the coal seam of different angles; Supporting intensity is high, guarantees production safety; Tunnel utilization rate is high, the broken rock engineering quantity during decreasing driving, and driving progress is fast.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: 1 back timber, 2 downside canopy legs, 3 high side canopy legs, 4 footing pieces, 5 card cables.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in drawings: a kind of colliery telescoping shoring column, back timber 1 is connected with between downside canopy leg 2 and high side canopy leg 3, downside canopy leg 2 and high side canopy leg 3 are oppositely arranged, and described high side canopy leg 3 is connected with bottom for leg-of-mutton footing piece 4, and described each junction is all fixed with card cable 5; Described downside canopy leg 2 is arcuate structure, all the other positions linearly structure with back timber 1, back timber 1 with the link of high side canopy leg 3; The cross section of described back timber 1, downside canopy leg 2 and high side canopy leg 3 is U-shaped.
When colliery telescoping shoring column described in the utility model is installed, according to the angle in coal seam, precalculate the position relationship between back timber 1 and center line in roadway, during construction, place back timber 1 according to the inclination angle in coal seam, then downside canopy leg 2, high side canopy leg 3 and footing piece 4 are installed, finally fix with card cable 5.
The utility model structure is simple, simple installation, adapts to the coal seam of different angles; Supporting intensity is high, guarantees production safety; Tunnel utilization rate is high, the broken rock engineering quantity during decreasing driving, and driving progress is fast.
The non-detailed portion of the utility model is known technology, and the usual change that those skilled in the art carries out within the scope of technical solutions of the utility model or replacement all should be included in protection domain of the present utility model.
Claims (2)
