Abstract
A kind of novel hydraulic expansion anchor rod, belongs to mining tunnel supporting field.It is mainly characterized by：Expansion type flap sleeve pipe is provided with the middle part of anchor pole, flap cannula tip is made up of the four arc valve parts docking being along the circumferential direction distributed, the angle of each arc valve part two ends correspondence flap casing axis is 90 °, bottom is ordinary casing, whole flap casing pipe sleeve is on anchor pole, tabular sleeve pipe top and bottom ends are contacted with helping swollen anchor bar body and top bracing plate| respectively, wherein helping swollen anchor bar body to be divided into helps swollen anchor bar body to help swollen anchor bar body with, top bracing plate| and annular hydraulic column contacts, and annular hydraulic pillar is connected with hydraulic cavities, dual-purpose valve of the hydraulic cavities through connection anchor pole bottom in the body of rod.The utility model easy construction, installation accuracy requires low, can be reclaimed without carrying out slip casting, and using after finishing, improve utilization rate.
Description
Technical field
The utility model is related to the roadway support equipment in mining, and in particular to a kind of novel hydraulic expansion anchor rod.
Background technology
Suspension roof support refers to adopt in the earth's surface engineering and tunnel, stope etc. such as side slope, ground deep basal pit underground chamber are constructed
A kind of its support reinforcement mode, is especially widely used in current mining support field.Specifically with gold
Roofbolt is made in category part, wooden piece, polymer member or other materials, squeezes into earth's surface rock mass or the pre-drilled hole of chamber surrounding rock body
In, utilize its head, the special tectonic of the body of rod and afterbody supporting plate（Also can be without）, or dependent on cohesive action by country rock and stably
Rock mass is combined together and produces suspension effectiveness, combination beam effect, reinforcing effect, to reach the purpose of supporting.Presently used
Various anchor poles, the requirement for installation is higher, relates generally to the side such as precision, the cooperation of parameters, moment of torsion of rig of drilling
Face, the tunnel adaptability for various complex situations is poor, and suspension roof support applies especially when construction environment is very severe
Work is very difficult.
The content of the invention
In order to overcome the existing various not enough and shortcomings of suspension roof support, the purpose of this utility model is to provide a kind of New
Compression swelling anchor pole, solves installation accuracy height, the problem of affected by environment big.
To achieve these goals, the technical solution adopted in the utility model is as follows：
A kind of novel hydraulic expansion anchor rod, including dual-purpose valve（It is made up of check valve and feather valve）, nut, supporting plate, hydraulic pressure
Chamber, flap sleeve pipe, top bracing plate|, annular hydraulic pillar, anchor pole, under help swollen anchor bar body, on help swollen anchor bar body.It is mainly characterized by：
Certain thickness expansion type flap sleeve pipe is provided with the middle part of anchor pole（Flap sleeve pipe is made up of the larger special material of rigidity, in ring
Can self-resetting after shape hydraulic prop pressure release）, flap cannula tip docks structure by four arc valve parts being along the circumferential direction distributed
Into the angle of each arc valve part two ends correspondence flap casing axis is 90 °, and bottom is ordinary casing, whole flap casing pipe sleeve
On anchor pole, flap sleeve pipe top and bottom ends are contacted with helping swollen anchor bar body and top bracing plate| respectively, wherein helping swollen anchor bar body to be divided into helps swollen
Anchor bar body and under help swollen anchor bar body, it is upper and lower to help swollen anchor bar body to be conically shaped body, in order to ensure upper and lower to help swollen anchor bar body to be embedded in
In flap sleeve pipe, the internal diameter of the arc valve part of the upper and lower external diameter for helping swollen anchor bar body and flap sleeve pipe is set to match, top bracing plate| and ring
Shape hydraulic prop is contacted, and annular hydraulic pillar is connected with hydraulic cavities, and hydraulic cavities connect dual-purpose valve, outside liquid through the body of rod is interior
It can be injected by dual-purpose valve, and pressure release, dual-purpose valve connection anchor pole end can be carried out by dual-purpose valve.
The beneficial effects of the utility model are：
Anchor pole is put into and drills and reaches specified location, without carrying out slip casting, passes through the annular in the middle part of hydraulic action anchor pole
Flap set tube top is constantly helped swollen anchor bar body to help swollen anchor bar body, four arc valve parts warp of flap sleeve pipe with by hydraulic prop upwards
Help swollen anchor bar body constantly to be expanded after acting on, increase each angle in 90 ° between the frictional force of anchor pole and rock mass, and arc valve part, because
The stress of flap sleeve pipe and country rock can be effectively dispersed to four anchoring positions by this, and pressure release can be carried out after being scrapped in tunnel will
Anchor recovering is reused, and easy construction, and construction precision requires low.
Brief description of the drawings
Fig. 1 is the front view of novel hydraulic expanding type recoverable anchor rod.
Fig. 2 is A-A profiles.
Fig. 3 is B-B profiles.
Wherein 1 is dual-purpose valve；2 be nut；3 be supporting plate；4 be hydraulic cavities；5 be flap sleeve pipe；6 be top bracing plate|；7 be annular
Hydraulic prop；8 be anchor pole；Swollen anchor bar body is helped under 9；10 be above to help swollen anchor bar body.
Embodiment
The utility model is further discussed below below in conjunction with accompanying drawing.
With reference to the accompanying drawings 1, a kind of novel hydraulic expansion anchor rod, including main anchor pole 8, it is mainly characterized by setting in the middle part of anchor pole
Have an expansion type flap sleeve pipe 5, the top of flap sleeve pipe 5 with above help swollen anchor bar body 10 or under help swollen anchor bar body 9 to contact, bottom and top
Fagging 6 is contacted, and top bracing plate| 6 is contacted with annular hydraulic pillar 7, and annular hydraulic pillar 7 is connected with hydraulic cavities 4, and anchor pole bottom is provided with
Supporting plate 3, the peripheral hardware nut 2 of supporting plate 3, hydraulic cavities 4 connect the end of anchor pole 8 through connection dual-purpose valve 1 in the body of rod, dual-purpose valve 1.By anchor pole
8 are put into drilling and reach specified location, and outside liquid injects hydraulic cavities 4 by dual-purpose valve 1, and subsequent annular hydraulic pillar 7 will
Flap sleeve pipe 5 push up help upwards swollen anchor bar body 10 and under help swollen anchor bar body 9, flap sleeve pipe 5 is softened therewith, then touches rock
Body, increases the frictional force of anchor pole and rock mass, and pressure release, the He of annular hydraulic pillar 7 can be carried out by dual-purpose valve 1 after being scrapped in tunnel
Flap sleeve pipe 5 is resetted respectively, and anchor recovering progress is used next time.
Helped on described swollen anchor bar body 10 and under help the group number of swollen anchor bar body 9 can be set according to actually required rock-bolt length,
Only illustrate one group herein.
