Description
Technical Field
The utility model relates to a tunnelling supporting equipment field. In particular to a turnover beam.
Background
In the existing tunneling support equipment system, turnover beams are mostly made of rigid materials, when the rigid material turnover beams meet a rugged roof, all the turnover beams cannot be in top contact, and the roof support effect is greatly reduced. And at present in order to guarantee that the roof beam body is difficult for the rupture, set up a plurality of reinforcing plates at the internal portion of roof beam, the structure is complicated, and the cost is higher.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a upset roof beam, simple structure, the roof beam body is firm, and the cost is lower. The turnover beam top surface can be fully abutted, the effective top protection area of the turnover beam is increased, the supporting effect of the turnover beam on the top plate is greatly improved, two turnover beam overlapping operations in the laying process are facilitated, the whole structure is stable, and potential safety hazards such as roof collapse and collapse caused by incomplete abutting of the existing rigid turnover beam are effectively avoided.
In order to solve the technical problem, the technical scheme of the utility model is that the turnover beam comprises a support, a beam body and a turnover driving device, wherein one end of the beam body is hinged with the support, one end of the turnover driving device is hinged with the support, and the other end of the turnover driving device is hinged with the side surface of the beam body; the top surface of the beam body is provided with a flexible material layer; the top surface and the side wall of the beam body are provided with a plurality of reinforcing ribs which are punched inwards at intervals.
On the basis of the scheme, the overturning driving device is a hydraulic jack.
On the basis of the scheme, the other end of the beam body is provided with a threaded hole.
On the basis of the scheme, the novel vertical beam structure further comprises a vertical beam, wherein a plurality of threaded holes are formed in the vertical beam, and the vertical beam is in threaded connection with the threaded holes of the beam bodies.
On the basis of the scheme, the flexible material layer is a rubber layer.
By adopting the technical scheme, the flexible material layer is arranged on the top surface of the beam body, so that the top surface of each turnover beam can be fully abutted, the effective top protection area of the turnover beam is increased, and the supporting effect of the turnover beam on the top plate is greatly improved; meanwhile, the lapping operation of the two turnover beams in the laying process is facilitated, the whole structure is stable, and the potential safety hazards of roof fall, collapse and the like caused by the fact that the existing rigid turnover beams cannot be completely abutted are effectively avoided. Because roof beam body top surface and lateral wall interval are provided with the strengthening rib of a plurality of inside punching press for the roof beam body is firm, is difficult for buckling, simple structure moreover, and the cost is lower.
