The polygonal hydraulic active support bracket has the advantages of overcoming the shortcomings of the convention support devices, realizing the active support of the bracket, yielding to high pressure, realizing the continuous effective support of the bracket, protecting from damage, along with simple structure, good effect and low cost.
Description
Technical field
The present invention relates to a kind of hydraulic support, especially a kind of polygon hydraulic pressure active support support that is applicable to that difform tunnel, chamber support are reinforced in the mining underground construction.
Background technology
The support reinforcement of the tunnel of underground constructions such as mining, chamber etc. is one of emphasis of underground scientific worker's research always, underground construction such as tunnel, chamber is often untimely because of supporting, the supporting resistance is not enough etc. causes supporting to be lost efficacy, and causes 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 the prior art, a kind of simple in structure, polygon hydraulic pressure active support support that supporting effect is good is provided.
Polygon hydraulic pressure active support support of the present invention comprises being located at the hydraulic pressure eyelid retractor of helping both sides respectively that two of hydraulic pressure eyelid retractor is hinged with support bar respectively, two help about be hinged with the roof timbering beam between two support bars; Two under helping about be hinged with base plate between two support bars and prop up backplate, the hydraulic pressure eyelid retractor comprises that portion of group props up backplate, the bottom that backplate props up in portion of group is provided with the articulated joint that is connected with lower support bar, portion of group props up backplate and 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 that backplate props up in portion of group 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; It is straight plate or the arc that adapts to support space that described base plate props up backplate; 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, at the serious top board middle part of tunnel and chamber support weakness, distortion, the effective support that the middle part is helped at base plate middle part, two, overcome the deficiency of existing support apparatus, realized the active support of support, realized the pressure that allows simultaneously, realized the continuous and effective supporting of support and exempted from damaging by pressure high pressure.When the distortion of tunnel or chamber is big; 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 the 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:
Polygon hydraulic pressure active support support of the present invention mainly is to prop up backplate 4, portion of group by hydraulic pressure eyelid retractor 1, support bar 2, roof timbering beam 3, base plate to prop up backplate 5, hydraulic cylinder 6, hydraulic column 7, hinge portion guiding bolt 8, gathering sill 9 and safety overflow valve 10 and constitute.Hydraulic pressure eyelid retractor 1 is hinged with support bar 2, and hydraulic pressure eyelid retractor 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 support bars 2 about two hydraulic pressure eyelid retractor 1 tops, roof timbering beam 3 is straight plate or arc, to adapt to support space top board shape; The hinge base plate props up backplate 4 between two support bars 2 of hydraulic pressure eyelid retractor 1 below, and base plate props up backplate 4 and is straight plate or arc, to adapt to support space top board shape.Hydraulic pressure eyelid retractor 1 comprises that portion of group props up backplate 5, the bottom that backplate 5 props up in portion of group is provided with the articulated joint that is connected with lower support bar, portion of group props up backplate 5 and 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 that backplate 5 props up in portion of group 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; Polygon hydraulic pressure active support support is generally octagon, also can increase and decrease the limit number as required.
During use, polygon hydraulic pressure active support support is placed in treats support space, in hydraulic cylinder 6, inject high pressure liquid, hydraulic cylinder 6 promotes hydraulic column 7 and outwards moves, the guiding bolt 8 that hydraulic column 7 promotes hinge portion moves in gathering sill 9, increase closed supporting and protection structure hoop girth, make roof timbering beam, portion of group prop up backplate, base plate and prop up backplate and respectively tunnel or chamber top, portion of group, base plate are formed the supporting resistance, active support is carried out in tunnel or chamber.Increase the polygon girth, prop up backplate and respectively tunnel or chamber top, portion of group, base plate are formed the supporting resistance, active support is carried out in tunnel or chamber thereby make roof timbering beam, portion of group prop up backplate, base plate.When the distortion of tunnel or chamber was big, 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 supporting tunnel or chamber; when reclaiming support, only needing to open the safety overflow valve release is recyclable support.
