Abstract
The invention provides a novel hydraulic expanded recyclable anchor rod, and belongs to the field of supporting of roadways. The novel hydraulic expanded recyclable anchor rod is mainly characterized in that an expanded petal-shaped sleeve is arranged nearby a top end of the anchor rod, the upper part of the petal-shaped sleeve is formed by connecting three arc-shaped petal pieces distributed in the peripheral direction, an included angle between two ends of each arc-shaped petal piece corresponding to the axis of the petal-shaped sleeve is 120 degrees, the lower part of the petal-shaped sleeve is still a common sleeve, the whole petal-shaped sleeve sleeves the anchor rod, the upper end and the lower end of the petal-shaped sleeve are respectively in contact with an expansion-assisting anchor rod head and a top support plate; the top support plate is positioned above retractable supports; the lower ends of the retractable supports are connected with a hydraulic cavity; and the hydraulic cavity penetrates in a rod body and is connected with a dual-purpose valve at the bottom of the anchor rod. A plurality of annular support plates which are connected with the retractable supports are arranged on the rod body of the anchor rod and positioned between a supporting plate and the petal-shaped sleeve, and included angles which are 120 degrees are formed among the three retractable supports connected with the annular supporting plates in each group. The novel hydraulic expanded recyclable anchor rod is convenient to construct and low in requirements of mounting precision; grouting is not required; the novel hydraulic expanded recyclable anchor rod can be recycled after being used; and the usage rate is increased.
Description
Technical field
The present invention relates to the Roadway Support Technology field in digging up mine, and in particular 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 used in the construction of the earth's surface engineering and tunnel, stope etc. such as side slope, ground deep basal pit underground chamber, is especially widely used in current mining support field.Roofbolt specifically is made with metalwork, wooden piece, polymer member or other materials, is squeezed into earth's surface rock mass or the pre-drilled hole of chamber surrounding rock body, using its head, the special tectonic of the body of rod and afterbody supporting plate（Also can be without）, or depend on cohesive action to be combined together country rock and rock mass stability and produce suspension effectiveness, combination beam effect, reinforcing effect, to reach the purpose of supporting.Presently used various anchor poles, requirement for installing is higher, relate generally to the aspects such as precision, the cooperation of parameters, the moment of torsion of rig of drilling, tunnel adaptability for various complex situations is poor, the construction of suspension roof support is very difficult especially when construction environment is very severe, other some anchor poles need just to be can be used after waiting slurry solidification, and not recyclable, cause waste.
The content of the invention
High for current most rockbolt installation requirements, geological conditions bad adaptability need to carry out slip casting, the problems such as not recyclable, it is an object of the invention to provide a kind of new hydraulic buckling type recoverable anchor rod.
The purpose of the present invention is achieved through the following technical solutions：
A kind of novel hydraulic expanding type recoverable anchor rod, including dual-purpose valve 1（It is made up of check valve and feather valve）, nut 2, supporting plate 3, hydraulic cavities 4, annular support plate 5, telescopic prop 6 and 8, anchor pole 7, top bracing plate| 9, flap sleeve pipe 10, help swollen anchor pole first 11.It is mainly characterized by：It is provided near the top of anchor pole 7 with certain thickness expansion type flap sleeve pipe 10（Flap sleeve pipe is made up of the larger special material of rigidity, can self-resetting after telescopic prop pressure release）,The top of flap sleeve pipe 10 is made up of the three arc valve parts docking being along the circumferential direction distributed,The angle of each arc valve part two ends correspondence flap casing axis is 120 °,Bottom is still ordinary casing,Whole flap sleeve pipe 10 is enclosed within anchor pole 7,Flap sleeve pipe it is upper,Lower end contacts with swollen anchor pole first 11 and top bracing plate| 9 is helped respectively,It is conically shaped body to help swollen anchor pole first 11,In order to ensure to help in the first 11 bottom insertion flap sleeve pipe 10 of swollen anchor pole,The internal diameter of the arc valve part of the external diameter and the upper end of flap sleeve pipe 10 that help first 11 bottom of swollen anchor pole is set to match,Top bracing plate| 9 is located on telescopic prop 8,The lower end of telescopic prop 8 is connected with hydraulic cavities 4,Hydraulic cavities 4 connect dual-purpose valve 1 through the body of rod is interior,Outside liquid can be injected by dual-purpose valve 1,And pressure release can be carried out by dual-purpose valve 1,The connection anchor pole of dual-purpose valve 1 end.Multigroup annular support plate 5 being connected with telescopic prop 6 is disposed with anchor rod body between supporting plate 3 and flap sleeve pipe 10, every group of 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 telescopic props being connected with annular support plate in every group, zigzag improved mat is equipped with outside described annular support plate, with increasing friction force.
The beneficial effects of the invention are as follows：
Anchor pole is put into and drills and reach specified location, slip casting need not be carried out, both sides effect is produced by hydraulic pressure, on the one hand, constantly flap sleeve pipe is pushed up upwards by top bracing plate| telescopic prop at the top of anchor pole, make three arc valve parts of flap sleeve pipe through helping swollen anchor pole head constantly to be expanded after acting on, increase the frictional force of anchor pole and rock mass；Annular support plate in the middle part of another aspect anchor pole produces larger frictional force under hydraulic action with rock mass, so as to ensure the rock tight, wedge fit of annular support plate and drilling surrounding.The stress of anchor pole is effectively dispersed to its four anchoring positions by the effect of these two aspects, and can carry out pressure release after tunnel is scrapped reuses anchor recovering.
