Description
Technical field
The utility model relates to a kind of mining machinery, is specifically related to a kind of mining self-locking anchor bar of supporting roadway surrounding rock.
Background technology
In supporting roadway surrounding rock field, there is multiple support anchor rod at present, by anchorage style, substantially can be divided into bonded, mechanical type etc.Bonded anchoring rod, adopts cementitious material, and the body of rod and brill drill hole wall are bonded together, adhesion stress with Anchor Agent provides anchored force, and its anchored force determines by the adhesion stress of cementitious material, and anchored force source is single, anchored force is little, does not reach the requirement of roadway support to anchored force.Mechanical type anchoring rod adopts anchor pole surface texture to improve and the frictional force of drill hole wall improves anchored force, although anchored force obviously improves, but anchored force size immobilizes, cannot anchored force be regulated for the actual conditions of country rock, anchor pole is very large at the process resistance of putting into boring simultaneously, is unfavorable for improving the efficiency of surrounding rock supporting.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of mining self-locking anchor bar, and it comprises distensible self-locking head, anchor pole main body and anchor rod pallet board.Distensible self-locking head is along with anchor pole main body and threaded sleeve is screwed into generation radial dilatation, after expansion, fully increase with drill hole wall contact raising anchored force.
The utility model is to adopt following technical scheme to realize: a kind of mining self-locking anchor bar, it comprises anchor rod pallet board, anchor pole main body and self-locking head.It is characterized in that: described anchor pole main body is the circular body of rod, its middle part makes screw thread.Described anchor rod pallet board is arranged on the outer end of anchor pole main body.Described self-locking head is comprised of threaded sleeve, cover pipe connector, connecting rod I and connecting rod II.Described threaded sleeve is tubular body, and threaded sleeve is connected with anchor pole main body screw.Described cover pipe connector is cylinder, and one end of cover pipe connector makes counterbore, and cover pipe connector is inserted in anchor pole body front end in the mode being slidably connected, and the other end of cover pipe connector is taper.Described connecting rod I and connecting rod II are rhabodoid, and connecting rod I and connecting rod II have many, and one end of connecting rod I is hinged by bolt I and hinged-support I.The other end of connecting rod I is hinged by one end of jointed shaft and connecting rod II.The other end of connecting rod II is hinged by bolt II and hinged-support II.Described hinged-support I is fixed on threaded sleeve.Described hinged-support II is fixed on cover pipe connector.
Described connecting rod I and connecting rod II are two, and every connecting rod I and connecting rod II form one group of linkage, and two groups of linkages are symmetrically distributed in anchor pole main body both sides.
The beneficial effects of the utility model are: anchor pole main body both sides adopt self-locking head as ingredient, thereby while installing and using, by being screwed into of anchor pole main body, open distensible self-locking head and improve self-locking head for the grip of drill hole wall, the anchoring effect of anchor pole and the control accuracy of grip have been strengthened, anchor pole is put into the resistance force diminishes of boring procedure, reduced workman's labour intensity, improve the simple and easy degree of construction, and can improve anchored force according to the linkage of the difference increase self-locking head of operating mode.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Accompanying drawing is mining self-locking anchor bar structural representation of the present utility model.
In accompanying drawing: 1, anchor rod pallet board, 2, anchor pole main body, 3, threaded sleeve, 4, hinged-support I, 4-1, hinged-support II, 5, bolt I, 5-1, bolt II, 6, connecting rod I, 6-1, connecting rod II, 7, jointed shaft, 8, self-locking head, 9, cover pipe connector.
The specific embodiment
As shown in drawings, mining self-locking anchor bar of the present utility model, it comprises anchor rod pallet board 1, anchor pole main body 2 and self-locking head 8.It is characterized in that: described anchor pole main body 2 is the circular body of rod, its middle part makes screw thread.Described anchor rod pallet board 1 is arranged on the outer end of anchor pole main body 2.Described self-locking head 8 is comprised of threaded sleeve 3, cover pipe connector 9, connecting rod I 6 and connecting rod II 6-1.Described threaded sleeve 3 is tubular body, and threaded sleeve 3 is threaded with anchor pole main body 2.Described cover pipe connector 9 is cylinder, and one end of cover pipe connector 9 makes counterbore, and described counterbore is inserted in anchor pole main body 2 front ends in the mode being slidably connected, and while making 2 rotation of anchor pole main body, is more prone to convenient, and the other end of cover pipe connector 9 is taper.Described connecting rod I 6 and connecting rod II 6-1 are rhabodoid, and connecting rod I 6 and connecting rod II 6-1 have many.One end of connecting rod I 6 is hinged by bolt I 5 and hinged-support I 4.The other end of connecting rod I 6 is the hinged composition linkage in one end with connecting rod II 6-1 by jointed shaft 7.The other end of connecting rod II 6-1 is hinged by bolt II 5-1 and hinged-support II 4-1.Described hinged-support I 4 is fixed on threaded sleeve 3.Described hinged-support II 4-1 is fixed on cover pipe connector 9.
