Abstract
The invention discloses a front exploring beam for a heading surface anchor rod support, which consists of an anchor rod and a double-pin hinged top beam. A saddle-shaped upper connection plate is fixed on the anchor rod through a nut and a backing plate; two wire through bolts with equal lengths are suspended at two ends of the upper connection plate; an upper clamping nut and a lower clamping nut are rotationally installed on each bolt; a middle clamping plate and an inverted saddle-shaped lower connection plate are installed on a bolt bar between the upper clamping nut and the lower clamping nut in a penetrating manner; and the double-pin hinged top beam is clamped between the middle clamping plate and the lower connection plate. Compared with the prior art, the front exploring beam has the advantages that the front exploring beam can be adjusted along with the uneven top surface of an entry or a tunnel; the top beam is tightly attached onto the rock surface, and the contact surface is increased to prevent roof rock falling.
Description
Technical field
The present invention relates to a kind of forestope that is used for coal mine roadway or tunnel roof temporary lining, especially a kind of driving face bolt support forestope.
Background technology
At present, when coal mine roadway or tunnel piercing, generally use bolting with wire mesh, when driving, the employing that the temporary lining of meeting head on has is hung pallet and is protected the top under roll bolt, and the employing anchor pole that has is hung ring belt iron pipe or long fine strain of millet down, comes interim supporting roof.Because the end face in tunnel or tunnel is up-and-down, being subjected to it to influence top board must also be up-and-down, therefore, above various methodologies all exists forestope and little, the every exposure one place's top board of top board contact area, the whole reach of forestope, and supporting intensity is low, the workman is awkward, roof fall, falling rocks take place easily, bring hidden danger to safety in production, human casualty accident happens occasionally.Therefore, designing and a kind ofly can adjust, make back timber to be close to scar, increase contact surface with the up-and-down end face in tunnel or tunnel, prevent the driving face bolt support forestope of roof fall falling rocks, be the present technical issues that need to address.
Summary of the invention
Technical problem to be solved by this invention provides a kind ofly can be adjusted, make back timber to be close to scar, increase contact surface with the up-and-down end face in tunnel or tunnel, prevents the driving face bolt support forestope of roof fall falling rocks.
The technical scheme that the present invention solves its technical problem is:
Driving face bolt support forestope, form by anchor pole and double-pin articulated roof beam, on anchor pole, be fixed with shape of a saddle upper junction plate by nut and backing plate, in the suspention of the two ends of upper junction plate two isometric harness cord bolts are arranged, be installed with the chucking nut on the bolt and tightening nut down, tighten nut and be coated with middle clamp and the lower connecting plate of falling the shape of a saddle on the shank of bolt between the chucking nut down last, described double-pin articulated roof beam is installed between middle clamp and the lower connecting plate.
The technical scheme that the present invention solves its technical problem can also be:
The anchor pole fixing hole of upper junction plate of the present invention is a slotted hole, and the width of the saddle groove of described lower connecting plate is greater than the width of double-pin articulated roof beam.
The present invention is installed with the upper junction plate hold-down nut on the bolt of upper junction plate bottom.
Compared with prior art, the present invention has and can adjust, make back timber to be close to scar, to increase contact surface with the up-and-down end face in tunnel or tunnel, prevents the advantage of roof fall falling rocks.

The specific embodiment
As shown in the figure, driving face bolt support forestope, form by anchor pole 4 and double-pin articulated roof beam 9, it is characterized in that: on anchor pole 4, be fixed with shape of a saddle upper junction plate 1 by nut 3 and backing plate 2, in the suspention of the two ends of upper junction plate 1 two isometric harness cord bolts 6 are arranged, be installed with chucking nut 8 on the bolt 6 and tightening nut 11 down, tighten nut 8 and be coated with middle clamp 7 and the lower connecting plate of falling the shape of a saddle 10 on the shank of bolt between the chucking nut 11 down last, described double-pin articulated roof beam 9 is installed between middle clamp 7 and the lower connecting plate 10.The anchor pole fixing hole of described upper junction plate 1 is a slotted hole, and the width of the saddle groove of described lower connecting plate 10 is greater than the width of double-pin articulated roof beam 9.On the bolt 6 of upper junction plate 1 bottom, be installed with upper junction plate hold-down nut 5.
