Description
Technical field
The present invention relates to a kind of hydraulic support, the polygonal hydraulic active support bracket that in especially a kind of underground construction that is applicable to dig up mine, difform tunnel, chamber support are reinforced.
Background technology
The support reinforcement of the tunnel of the underground constructions such as mining, chamber etc. is one of emphasis of underground scientific worker's research always, the underground construction such as tunnel, chamber often untimely because of supporting, Support Resistance is inadequate etc. causes supporting to be lost efficacy, and causes the destructions such as tunnel, chamber, casualties etc.The supporting of underground construction needs the more efficiently initiatively support apparatus of immediate support, ensures the effective support of underground construction.
Summary of the invention
The objective of the invention is to overcome the deficiency in prior art, a kind of simple in structure, polygonal hydraulic active support bracket that supporting effect is good is provided.
Polygonal hydraulic active support bracket of the present invention comprises being located at respectively the hydraulic pressure support device of helping both sides that two of hydraulic pressure support device is hinged with respectively support bar, is hinged with the roof timbering beam between two two of the left and right of helping support bars; Be hinged with the base plate retaining-plate between two two of left and right support bars under helping, the hydraulic pressure support device comprises section of side retaining-plate, the bottom of section of side retaining-plate is provided with the articulated joint that is connected with lower support bar, section of side retaining-plate is provided with hydraulic cylinder, hydraulic cylinder is provided with the hydraulic column that matches with it, hydraulic column is provided with the guiding bolt that is hinged with upper support bar, and the both sides of section of side retaining-plate are provided with the support bar gathering sill, and hydraulic cylinder is provided with safety overflow valve.
Described roof timbering beam is straight plate or the arc that adapts to support space; Described base plate retaining-plate is straight plate or the arc that adapts to support space; Described support bar is straight-bar or the bent stick that adapts to support space.
Beneficial effect: the present invention is used for the supporting of underground construction tunnel and chamber, the effective support at middle part is helped at the top board middle part weak for tunnel and chamber support, that distortion is serious, base plate middle part, two, overcome the deficiency of existing support apparatus, realized the active support of support, realized simultaneously the pressure that allows to high pressure, realized the continuous and effective supporting of support and exempted from damaging by pressure.When the distortion of tunnel or chamber is larger; safety overflow valve is opened; release portion liquid; support still can carry out supporting to tunnel or chamber; protection tunnel or chamber exempt from destruction, and effective support tunnel or chamber are when reclaiming support; only needing to open the safety overflow valve release is recyclable support, reduces supporting difficulty and the cost of tunnel or chamber.It is simple in structure, and cost is low, and supporting effect is good, has practicality widely.

The specific embodiment
Below in conjunction with accompanying drawing, enforcement of the present invention is further described:
Polygonal hydraulic active support bracket of the present invention is mainly to be made of hydraulic pressure support device 1, support bar 2, roof timbering beam 3, base plate retaining-plate 4, section of side retaining-plate 5, hydraulic cylinder 6, hydraulic column 7, hinge section guiding bolt 8, gathering sill 9 and safety overflow valve 10.Hydraulic pressure support device 1 is hinged with support bar 2, and hydraulic pressure support device 1 is two, is separately fixed at both sides and helps, and support bar 2 has four; Hinged roof slab supporting beam 3 between two of the left and right support bar 2 of two hydraulic pressure support device 1 tops, roof timbering beam 3 is straight plate or arc, to adapt to support space top board shape; Hinge base plate retaining-plate 4 between two support bars 2 of hydraulic pressure support device 1 below, base plate retaining-plate 4 is straight plate or arc, to adapt to support space top board shape.Hydraulic pressure support device 1 comprises section of side retaining-plate 5, the bottom of section of side retaining-plate 5 is provided with the articulated joint that is connected with lower support bar, section of side retaining-plate 5 is provided with hydraulic cylinder 6, hydraulic cylinder 6 is provided with the hydraulic column 7 that matches with it, hydraulic column 7 is provided with the guiding bolt 8 that is hinged with upper support bar, the both sides of section of side retaining-plate 5 are provided with support bar gathering sill 9, and hydraulic cylinder 6 is provided with safety overflow valve 10.Support bar 2 is straight-bar or the bent stick that adapts to support space; Polygonal hydraulic active support bracket is generally octagon, also can increase and decrease as required the limit number.
During use, polygonal hydraulic active support bracket is placed in treats support space, inject high pressure liquid in hydraulic cylinder 6, hydraulic cylinder 6 promotes hydraulic column 7 and outwards moves, the guiding bolt 8 that hydraulic column 7 promotes hinge section moves in gathering sill 9, increase closed supporting and protection structure hoop girth, make roof timbering beam, section of side retaining-plate, base plate retaining-plate form Support Resistance to tunnel or chamber top, section of side, base plate respectively, active support is carried out in tunnel or chamber.Increase the polygon girth, thereby make roof timbering beam, section of side retaining-plate, base plate retaining-plate form Support Resistance to tunnel or chamber top, section of side, base plate respectively, active support is carried out in tunnel or chamber.When the distortion of tunnel or chamber was larger, safety overflow valve 10 was opened, release portion liquid; support still can carry out supporting to tunnel or chamber, and protection tunnel or chamber exempt from destruction, play the effect of supported laneway or chamber; when reclaiming support, only needing to open the safety overflow valve release is recyclable support.
