Abstract
The utility model discloses a double-K type steel belt for anchoring. The double-K type steel belt for anchoring is characterized in that the double-K type steel belt is provided with a straight board (1) in the middle and symmetrically provided with K-shaped openings (2) at the two ends. Screw holes (3) are formed in the bottom ends of the K-shaped openings (2). The double-K type belt for anchoring has the advantages of being large in peripheral supporting area, high in bending-resistant capacity, convenient to install and detach, and good in anchoring effect, and is suitable for supporting of underworkings of mines.
Description
Technical field:
The utility model belongs to the technical field of mining machinery manufacture, and in particular to a kind of mining anchorGu with double K-type steel bands, it is adapted to mine down-hole tunnel supporting.
Background technology:
At present, the big portion of supporting that underground coal mine is used is using concrete-steel band small area supportSlab supporting, although concrete-steel band is lightweight, processing is simple, but stiffness very little. HaveEffect supporting area is small, poor to roof timbering effect, and also having to use has steel band of model branchShield, the supporting area that increased around stiffness and anti-bending strength, but its anchor pole is small,Particularly when roof pressure is big, supporting failure is easily caused, causes roof collapse,There is roof fall accident when serious. It is difficult to adapt to underground big cross section, large span it is mined outTunnel, especially in complex conditions such as the common high-ground stress for arriving of mine down-hole moreThe security for demonstrate,proving its supporting is difficult to ensure, the anchoring of its supporting is also anchored using bolt,It is inconvenient in the presence of assembly and disassembly, the big defect of construction labour intensity.
Utility model content:
The purpose of this utility model is exactly to overcome the above not enough, there is provided one kindEnhancing mine down-hole tunnel supporting intensity, expands supporting area, and be convenient to mount and dismount spiritLiving, labour intensity is small, the good anchoring of anchoring property pair K-type steel bands.
The utility model is achieved in that the double K-type steel bands of described anchoring,It is characterized in that it is straight panel 1 to set a centre, two ends are symmetrically arranged with K-typeDouble K-type steel bands of mouth 2, screw hole 3 is provided with the bottom of K-type mouthful 2. ItsOperation principle is to be fixed on coal and rock by one of anchor cable or anchor pole, and other end is sequentiallyIt is firm with nut through steel band screw hole 3, pallet.
Anchoring of the present utility model has in the especially big top board of pressure with double K-type steel bandsMiddle anchoring, increases the bending strength of steel band, increased the supporting area around anchor pole,Prevent steel band from tearing and ensureing the discharge space of steel band, greatly improve roof timberingBearing capacity and anti-bendability, expand the advantage of effective support area.
