Description

A kind of novel hydraulic expanding type recoverable anchor rod
Technical field
This utility model relates to the Roadway Support Technology field in mining, is specifically related to a kind of novel hydraulic expanding type recoverable anchor rod.
Background technology
Suspension roof support refers to a kind of its support reinforcement mode adopted in the earth's surface engineerings such as side slope, ground deep basal pit and the underground chamber such as tunnel, stope are constructed, and is especially widely used in current mining support field. Roofbolt is made specifically with metalwork, wooden piece, polymer member or other materials, squeeze in earth's surface rock mass or the pre-drilled hole of chamber surrounding rock body, utilize its head, the special tectonic of the body of rod and afterbody supporting plate (also can), or depend on cohesive action and country rock and rock mass stability are combined and produces suspension effectiveness, combination beam effect, reinforcing effect, to reach the purpose of supporting. Presently used various anchor poles, requirement for installing is higher, the aspects such as the moment of torsion relating generally to the precision of boring, the cooperation of parameters, rig, tunnel adaptability for various complex situations is poor, especially when construction environment is very severe time, the construction of suspension roof support is very difficult, additionally some anchor pole just can use after needing to wait slurry solidification, and not recyclable, causes waste.
Summary of the invention
Requiring height, geological conditions bad adaptability at present most rockbolt installations, need to carry out slip casting, the problem such as not recyclable, the purpose of this utility model is to provide a kind of novel hydraulic buckling type recoverable anchor rod.
The purpose of this utility model is achieved through the following technical solutions:
A kind of novel hydraulic expanding type recoverable anchor rod, is made up of check valve and feather valve including dual-purpose valve 1(), nut 2, supporting plate 3, hydraulic cavities 4, annular support plate the 5, first telescopic prop 6 and the second telescopic prop 8, anchor pole 7, top bracing plate| 9, flap sleeve pipe 10, help swollen anchor pole head 11.It is mainly characterized by comprising: that the top of anchor pole 7 is arranged around having certain thickness expansion type flap sleeve pipe 10(flap sleeve pipe and is made up of the special material that rigidity is bigger, can self-resetting after the second telescopic prop 8 pressure release), flap sleeve pipe 10 top is made up of three the arc lobe part docking being along the circumferential direction distributed, the angle of each arc lobe part two ends correspondence flap casing axis is 120 ��, bottom is ordinary casing, whole flap sleeve pipe 10 is enclosed within anchor pole 7, flap sleeve pipe upper, lower end contacts with helping swollen anchor pole head 11 and top bracing plate| 9 respectively, helping swollen anchor pole head 11 is conically shaped body, in order to ensure to help swollen anchor pole head 11 bottom to embed in flap sleeve pipe 10, the internal diameter helping the arc lobe part of the external diameter of swollen anchor pole head 11 bottom and flap sleeve pipe 10 upper end is made to match, top bracing plate| 9 is positioned on the second telescopic prop 8, second telescopic prop 8 lower end is connected with hydraulic cavities 4, hydraulic cavities 4 connects dual-purpose valve 1 in the body of rod, outside liquid can pass through dual-purpose valve 1 and inject, and dual-purpose valve 1 can be passed through and carry out pressure release, dual-purpose valve 1 connects anchor pole end. anchor rod body between supporting plate 3 and flap sleeve pipe 10 is provided with the many groups of annular support plates 5 being connected with the first telescopic prop 6, often group annular support plate is made up of three annular support plates being along the circumferential direction distributed, and it is mutually 120 �� of angles between three the first telescopic props being often connected with annular support plate in group, zigzag improved mat it is equipped with, with increasing friction force outside described annular support plate.
The beneficial effects of the utility model are:
Anchor pole is put into boring and arrives appointment position, without carrying out slip casting, the effect of two aspects is produced by hydraulic pressure, on the one hand, constantly flap sleeve pipe is upwards pushed up by top bracing plate| the second telescopic prop at anchor pole top, three the arc lobe parts making flap sleeve pipe are constantly expanded after helping swollen anchor pole head effect, increase the frictional force of anchor pole and rock mass; Annular support plate in the middle part of anchor pole produces bigger frictional force with rock mass under hydraulic action on the other hand, thus ensureing annular support plate and boring rock tight, wedge fit around. The stress of anchor pole is effectively dispersed to its four anchoring positions by the effect of these two aspects, can carry out pressure release and be reused by anchor recovering after tunnel is scrapped.

Fig. 2 is A-A profile.
Fig. 3 is B-B profile.
Wherein 1 is dual-purpose valve; 2 is nut; 3 is supporting plate; 4 is hydraulic cavities; 5 is annular support plate; 6 is the first telescopic prop; 8 is the second telescopic prop; 7 is anchor pole; 9 is top bracing plate|; 10 is flap sleeve pipe; 11 for helping swollen anchor pole head.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is further discussed below.
With reference to the accompanying drawings 1, a kind of novel hydraulic expanding type recoverable anchor rod, including main anchor pole 7, it is mainly characterized by near anchor pole top to be provided with expansion type flap sleeve pipe 10, flap sleeve pipe top is to help swollen anchor pole head 11, bottom is top bracing plate| 9, top bracing plate| is positioned on the second telescopic prop 8, the anchor pole other end is provided with supporting plate 3, supporting plate 3 peripheral hardware nut 2, is also provided with the first telescopic prop 6 in the middle part of anchor pole, first telescopic prop 6 upper end connects annular support plate 5, lower end connects hydraulic cavities 4, and hydraulic cavities 4 connects dual-purpose valve 1 in the body of rod, and dual-purpose valve 1 connects anchor pole 7 end. anchor pole is put in boring and is arrived appointment position, outside liquid injects hydraulic cavities by dual-purpose valve 1, first telescopic prop 6 subsequently, second telescopic prop 8 props up annular support plate 5 and flap sleeve pipe 10 respectively, flap sleeve pipe 10 constantly moves upward softened after helping the effect of swollen anchor pole head 11, then rock mass is touched, increase the frictional force of anchor pole and rock mass, rock mass is also produced pressure by the annular support plate 5 at middle part under the effect of the first telescopic prop 6, make between anchor pole and rock mass, to produce bigger frictional force, dual-purpose valve 1 can be passed through after tunnel is scrapped and carry out pressure release, annular support plate 5 and flap sleeve pipe 10 reset respectively, anchor recovering is carried out use next time.
5 groups of numbers of described annular support plate can set according to actually required rock-bolt length, only illustrates three groups at this.
Described annular support plate 5 is externally provided with zigzag improved mat, with increasing friction force.
