Description
Technical field
The utility model is related to colliery digging technology field, and in particular to support shield type flexible support.
Background technology
Coal is one of important energy, and coal is widely used in the fields such as electric power, transport.Therefore, coal resource
Excavate with exploiting significant.Colliery is generally divided into underground mine and open coal mine.When coal seam is remote from earth's surface, be typically chosen to
Tunnel digging coal is dug in underground, and this is underground mine.When distance of the coal seam away from earth's surface is close, it is typically chosen and directly peels off ground
Topsoil excavates coal, and this is open coal mine.China's overwhelming majority colliery belongs to underground mine.
Colliery is largely to be imbedded in underground, during coal mining, must use and arrive shield support.Shield support leads to
Often include back timber and supporting leg, back timber and supporting leg are hinged, and pass through the flexible gradient to adjust supporting leg of hydraulic jack.
Shield support needs to bear larger weight, and existing support is in the yielding fracture of weight, and service life is shorter.
Utility model content
The purpose of this utility model is offer support shield type flexible support, solves existing shield support variable in weight
Shape is broken, and causes the problem of service life is shorter.
The utility model is achieved through the following technical solutions：
Support shield type flexible support, including back timber, the back timber include multiple supporting plates be arrangeding in parallel, adjacent supports
Plate is connected by the first connector, and described supporting plate one end is hinged with the first supporting leg, and the other end is hinged with the second supporting leg, and described
The first hydraulic jack is provided between one supporting leg and supporting plate, the second hydraulic oil is provided between second supporting leg and supporting plate
Cylinder, the supporting plate includes multistage connecting plate, and adjacent connection plates are connected by the second connector, the length of second connector
For 50mm-100mm.
Existing support is under weight, and inside produces stress, and stress can not discharge, in the presence of stress support by
Stretching, yielding fracture, service life is shorter.
Back timber described in the utility model, the first supporting leg and the second supporting leg constitute support frame, wherein, pass through the first hydraulic jack
And second hydraulic jack the flexible folding that can realize the first supporting leg and the second supporting leg (between the first supporting leg and the second supporting leg
Distance), and then the whole height of support frame is adjusted, the length (the distance between adjacent connection plates) of second connector is difficult
It is excessive, the excessive structural stability for influencing whether support frame.
The utility model by supporting plate by being divided into multistage connecting plate, and adjacent connection plates are connected by the second connector,
Therefore, space is formed between adjacent connection plates, after supporting plate is stressed, is released alleviating in gap, it is to avoid should
Power caused deformation fracture in supporting plate, in this way, the utility model solves existing shield support in the yielding fracture of weight,
Cause the problem of service life is shorter.
Further, the second connector is steel chain.
Further, the second connector is detachable is arranged between 2 adjacent connection plates.
Specifically, detachable can be buckle structure.
Further, the second supporting leg includes the first linkage section, the second linkage section and supporting section, described first linkage section one end
It is fixedly connected with supporting plate, the other end is hinged with the second linkage section, second linkage section one end is hinged with the first linkage section, the other end
It is hinged with supporting section.
Said structure is hinged for multistage, can preferably realize the regulation to the second supporting leg.
Further, back timber, the first supporting leg and the second supporting leg are made of steel.
The steel are prior art material, with preferable intensity and hardness, and are difficult corrosion.
The utility model compared with prior art, has the following advantages and advantages：
The utility model by supporting plate by being divided into multistage connecting plate, and adjacent connection plates are connected by the second connector,
Therefore, space is formed between adjacent connection plates, after supporting plate is stressed, is released alleviating in gap, it is to avoid should
Power caused deformation fracture in supporting plate.
