Abstract
The utility model discloses a shed leg reinforcer for the heading faces of coalmines, which comprises two fixing wedges and two guard plates, wherein the two fixing wedges are inserted into the flooralong both sides of a shed leg, the two guard plates cling to both sides of the shed leg, and the exposed ends of the fixing wedges and the guard plates are provided with corresponding holes, and arefixed together by screws for the holes. The field practice proves that the reinforcer ensures the stability of a supporting shed and that reinforcing operation is convenient.
Description
Technical field
The utility model relates to the supporting canopy that driving face in coal mine is used.
Background technology
The digging laneway of the many middle and small scale coal mines of China still adopts the temporary lining of frame canopy at present.When blowing out, knock the supporting canopy easily down.For preventing down canopy, generally be to adopt concrete reinforcings of taking root, this method not only labour intensity greatly, waste material, and setting time is longer, is blown out easily again and breaks.
The utility model content
The purpose of this utility model is to provide a kind of simple and easy bracing means that prevents down canopy.
Technical scheme is: it comprises two two backplates fixedly carving and be close to canopy leg both sides that are inserted into from canopy leg both sides the floor, is processed with corresponding hole on dew end of fixedly carving and the backplate, is fixed together with screw rod by the hole.
Using method is: earlier the float coal (or floating cash) around the canopy leg is cleaned out, carried out perforating with air drill or wind coal borer at two side direction base plates near the canopy leg then, jewel hole will be parallel to the force direction that is subjected to of canopy leg as far as possible, and eye is dark to be not less than 0.5 meter.After having beaten eye, fixed wedge is beaten in the floor rock, then two backplates are embraced the canopy leg, penetrate screw rod, fastening nut can play the effect of reinforcing the canopy leg.
The utility model has the advantages that: through the field practice checking, use this bracing means, guaranteed the stability of supporting canopy, reinforce easy to operate.Reduced worker's labour intensity; And instantaneous anchored force is big, has improved safety factor greatly.In addition, the utility model volume is little, in light weight, be convenient to processing, reclaim the reusability height, is suitable for working environment at coal mines, and particularly its use value more can be brought into play in the more frequent tunnel of opening the door, tunnel during Pillar Recovery.
