Abstract
The utility model discloses an it is recoverable from anchor type stock comprises inside anchor head (1), outside sleeve pipe (5), tray (3), nut (4), recess (2), the recoverable body of rod (7), threaded connection (9), cover intraduct cyclic annular wedge protruding (8), outside cling compound protruding (6). Outside cover intraduct has cyclic annular wedge protruding, has on the inside body of rod and overlaps the protruding wedge recess that corresponds of the cyclic annular wedge of intraduct, and the sleeve pipe is for there being the seam steel pipe, and during the installation, through exerting the pulling force to inside body of rod afterbody, the body of rod passes through the wedge body extrusion sleeve pipe, can make the expansion of outside sleeve pipe, makes the sleeve pipe outer wall hug closely the drilling inner wall, realizes the anchor end anchor. The utility model discloses it is low to solve traditional stock anchor power, and construction process is complicated, and reuse rate hangs down, struts the high scheduling problem of expense, can improve roadway support's construction quality by a wide margin, improves the stability of country rock.
Description
Technical field
The utility model relates to a kind of recyclable from anchor type anchor pole, and this device can make the construction quality of roadway support be improved, and can solve conventional anchor anchored force low, installs complicated, the problems such as not reproducible utilization, supporting expense height.
Background technology
Bolt support is as the effective drift support type of one, due to the invigoration effect to roadway surrounding rock intensity, the stability of country rock can be significantly improved, in addition have into that lane speed is fast, labour intensity alleviates, improves drift section utilization rate, Simplified flowsheet, obviously improves the advantage such as operating environment and safety production condition, the economic benefit of mine can be improved, thus become the main support form of one of coal mining enterprise's mine laneway, represent the main development direction of colliery tunnel support technology.Since China's coal-mine promotes bolt support technology, bolt support technology is constantly reformed, but use resin anchoring agent to carry out anchoring, cost is too high.Therefore, how ensureing effective under the impregnable prerequisite of anchoring property must reducing costs, be the difficult problem that bolt support technology faces.
Summary of the invention
The utility model relate to a kind of can anchored end anchoring the novel anchor rod of recyclable recycling, this device can make the construction quality of roadway support be improved, and reduces because anchored force is not enough and fails to reach the problem that designing requirement causes wall rock destabilization.
A kind of recyclable from anchor type anchor pole, be made up of inner anchorage head, outer sleeve, pallet, nut, connecting thread, protruding, the outside antiskid projection of groove inside pipe casing ring-type wedge shape, pipe seam.It is characterized by: outer sleeve inside has ring-type wedge shape protruding, the inner body of rod there is with inside pipe casing ring-type wedge shape protruding corresponding wedge-shaped impression, sleeve pipe is seamed steel pipe, during installation, by applying pulling force to inner body of rod afterbody, the body of rod, by sphenoid squeezing bushing, can make outer sleeve expand, make sleeve outer wall be close to drill hole inner wall, realize full length fastening; During recovery, recyclable for the body of rod section is unloaded, can recycling be taken out.
As improvement, sleeve pipe is seamed steel pipe.
As improvement, the body of rod is divided into anchorage head and recyclable body of rod two parts, middle by being threaded.
As improvement, it is protruding that inside pipe casing is provided with ring-type wedge shape, and outside has antiskid protruding.
As improvement, the body of rod is provided with the protruding corresponding groove with inside pipe casing ring-type wedge shape.
As improvement, groove and ring-type wedge shape projection fit tightly.
The invention has the beneficial effects as follows: this project organization is simple, be convenient to install, in work progress, prestressed applying is not by time restriction, and the efficiency of construction of roadway support is improved; Sleeve pipe is seamed steel pipe, and casing diameter can increase; Jacket exterior has antiskid protruding, can increase the frictional force between anchor pole and drill hole inner wall, strengthens anchoring effect.This anchor pole, by frictional force anchoring, does not need to use Anchor Agent, solves in traditional anchoring process because of the hypodynamic problem of Anchor Agent anchoring; Anchor pole can recycle and reuse, and saving material can reduce support cost.

Five, detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following instance is used for the utility model is described, but is not used for limiting scope of the present utility model.
As shown in Figure 1, anchored end anchoring recoverable anchor rod is made up of inner anchorage head (1), outer sleeve (5), pallet (3), nut (4), groove (2), the recyclable body of rod (7), be threaded (9), inside pipe casing ring-type wedge shape projection (8), outside antiskid projection (6).
During installation, by applying pulling force to the inner body of rod (7) afterbody, the body of rod is by sphenoid (8) squeezing bushing (5), outer sleeve (5) can be made to expand, make sleeve outer wall be close to drill hole inner wall, the antiskid projection of sleeve outer wall can increasing friction force, realizes anchored end anchoring; During recovery, recyclable for the body of rod section is unloaded, can recycling be taken out.
As improvement, sleeve pipe is seamed steel pipe.
As improvement, it is protruding that inside pipe casing is provided with ring-type wedge shape, and outside has antiskid protruding.
As improvement, anchor rod body is made up of anchoring section and recyclable section, middle by being threaded.
As improvement, the body of rod is provided with the protruding corresponding groove with inside pipe casing ring-type wedge shape.
As improvement, groove and ring-type wedge shape projection fit tightly.
