Description
Technical field
The invention belongs to coal mine down-hole tunnel gib technical field, is related to a kind of enclosing at the top of coal mine down-hole tunnel
It integrally can quickly be moved in the case of the soft inbreak of coal, enclose the safety support device that the tiny fragments of stone, coal, etc. is not leaked in shielding entirely, and in particular to one kind is used for
Driving and the shield support of back production.
Background technology
At present in stope, particularly caving coal mining working face, two lane advance supports are the emphasis of roadway support
And difficult point.Reason is that for working face in exploitation process, the advanced 20 meters of inside ceiling panel pressure in two lanes is significantly greater than the other portions in tunnel
Point, moreover, advanced section is also constantly changing with the propulsion of working face.Existing supporting generally adds π using hydraulic prop
Section steel beam mode, this mode globality poor, needs are manually more, translational speed is slow and dangerous；Other such as combination beam type lanes
The advance timberings such as road support, double leval jib step type excavation support, most of complicated, action is cumbersome, and more with to top plate
Based on supporting, there is no supporting to roadway's sides, it is difficult to adapt to the soft coal seam easily emitted or country rock.
Publication No. CN203531931U Chinese patent discloses underground coal mine temporary support for drivage face equipment, bag
Include support, cylinder, hook and forestope, it is characterised in that support there are uniform vertically upward 4, and frame upper is equipped with symmetrical
2 groups of sliding equipments, sliding equipment includes hook, supporting plate, forestope and cylinder, and hook is on support, hook bottom dress
There is the supporting plate that transverse horizontal is arranged, there is horizontally disposed composition in the sliding channel of supporting plate between supporting plate and support
Forestope, cylinder is parallel in the forestope through attachment means, and there is stay hook the piston rod end of cylinder；Described connection dress
Put including the first fixed plate, the second fixed plate, screw bolt and nut, cylinder is in the first fixed plate, and the first fixed plate is through bolt
It is connected with the second fixed plate mounted in both sides inside forestope, bolt both ends have for fixed nut.Described hook is through upper
The pressing plate in portion is fixed on support；Described support is circular arc.The underground coal mine gib equipment is provided only with support, the branch
Frame belongs to horizontal support, and to the unrestrained then non-support ability of the coal tiny fragments of stone, coal, etc. from coal mine roadway inner top longitudinal direction.
Publication No. CN203308478U Chinese patent discloses gib frame, including left support plate, right support plate,
And some top plates, it is characterised in that also including left hydraulic cylinder, right hydraulic cylinder, and some upper hydraulic cylinders, the upper hydraulic cylinder
Both ends connect two pieces of top plates respectively, one end and the left support plate of described left hydraulic cylinder are hinged, and the other end is with being connected left support
The top plate of plate is hinged；One end of right hydraulic cylinder is hinged with right support plate, and the other end is hinged with being connected the top plate of right support plate；It is described
Upper hydraulic cylinder is asymmetric to be hinged on two pieces of top plates.By be hinged between the left support plate, each top plate and right support plate
It is connected, and operating angle can be regulated and controled by hydraulic system.The gib frame must get to specify by external force
Position, in concrete operations, waste time and energy, efficiency it is low.
Publication No. CN201802428U Chinese patent discloses temporary support device for coal mine heading, including pressure pin, connection
Part and cylinder；One end of pressure pin is provided with fixing device, and the other end is connected by connector with cylinder；Air inlet is provided with cylinder
Hole, the opening of air admission hole are provided with control valve；Non-slip feet is installed in the piston rod bottom of cylinder.The temporary support is in work
When making：That one end of pressure pin equipped with fixing device is placed on to the working face of firm explosion, the other end is connected by connector and cylinder
Connecing, top power is attributed to top plate cylinder angular adjustment to 50-55 degree, control valve is connected with external pressure pipe, so as to which cylinder must press,
Piston rod, which stretches out, makes support is dry to withstand top plate.The temporary support device for coal mine heading is only capable of realizing local supporting, for from non-branch
Mask then non-support ability, poor practicability.
In addition, existing support pattern, generally existing support process is complicated, the slow-footed problem of integer support, it is impossible to suitable
Answer the requirement of face mechanization high-efficiency mining.In addition, during tunnelling, no matter big gun pick or machine pick all refer in advance
Gib problem, the more original backwardness of current method, greatly affected driving speed and safety.It is therefore, a kind of overall
Property it is strong, movement is rapid, safe and efficient supporting is imperative.
