Technical Field
The utility model relates to a colliery advance support forestope technical field, more specifically the theory relates to a colliery is forestope roof beam body for advance support.
Background
The state stipulates that during construction of a coal mine tunnel or a tunnel, an advanced temporary support must be used, and the operation of an empty roof is strictly forbidden. At present, the U-shaped steel or I-shaped steel for supporting is reinforced by adopting a front canopy for advance supporting mostly on site.
The Chinese patent with the granted publication number of CN201865679U and the patent number of 201020244877.2 discloses a front canopy for supporting a tunneling working face frame shed, which is used for supporting a coal mine roadway U-shaped steel or I-shaped steel frame shed. A metal hinged beam is arranged on a U-shaped steel or I-shaped steel bracket and is clamped by a foot rest, the foot rest is provided with a left claw and a right claw at two ends of a connecting shaft, and a through hole on each claw penetrates through a fixing plate and a positioning pin. The problem of prior art iron chain or single-leg fixture fastening support swing not firm for the canopy is solved. However, when the device is used on site, 3-4 foreheads need to be installed on the U-shaped steel or I-shaped steel bracket for fixation, and the U-shaped steel or I-shaped steel bracket is unevenly stressed due to the fact that the U-shaped steel or I-shaped steel bracket positioning device is not installed on the metal hinged beam, so that the bracket is prone to unstable swinging. Therefore, in view of the above, the invention provides a more firmly fixed forepoling beam body for coal mine forepoling, which is a problem to be solved by the technical personnel in the field.
SUMMERY OF THE UTILITY MODEL
To above defect, the utility model provides a colliery is forestope roof beam body for advance support to solve a great deal of not enough of prior art.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a forepoling beam body for coal mine forepoling comprises a metal hinged beam body and a connecting pin; a steel support fixing stop block is welded on the right side of the top end of the metal hinged beam body, an adjustable stud is arranged on the left side of the steel support fixing stop block, the adjustable stud is installed on a nut plate through threads, and the nut plate is fixed on the top end of the metal hinged beam body; a fixed nut is arranged on the adjustable stud, and a square rotating block is fixed at one end of the adjustable stud, which is far away from the steel bracket fixed stop block; the metal hinged beam body is fixedly provided with a connecting rope fixing ring, and the connecting rope fixing ring is connected with an angle adjusting wedge through a connecting rope.
Preferably, a threaded hole is formed in the small head end of the angle adjusting wedge, and an anti-flying bolt is detachably mounted in the threaded hole.
The utility model has the advantages that: the steel bracket is more firmly fixed and has better effect by adding the steel bracket fixing stop block and the adjustable stud; through the arrangement of the anti-flying bolt, when the angle adjusting wedge is loosened, the anti-flying bolt blocks the angle adjusting wedge from falling off, so that the angle adjusting wedge is prevented from flying and falling off, and the safety of the angle adjusting wedge is improved.
