Abstract
The utility model provides a kind of anchoring of expansion automatically tooth post anchor pole, this expands anchoring tooth post anchor pole automatically a columniform body of rod, the body of rod is provided with body of rod screw thread, the front end of the body of rod is cone-shaped pointed cone head, lever front end is fitted with columniform anchor head, and the centre of anchor head is provided with axial through hole, is provided with the screw thread mated with spiral thread on anchor bolt in through hole, laterally be provided with 3 ~ 30 evenly spaced pilot holes in anchor head, cylin-drical tooth post is housed in pilot hole.This anchored force automatically expanding anchoring tooth post anchor pole is large, and the active area of Anchor Agent is large, and it is convenient to install, and structure is simple.
Description
Technical field
The utility model relates to a kind of anchor pole of mine, and the one that especially can expand outwardly anchoring tooth post expands anchoring tooth post anchor pole automatically.
Background technology
Anchor pole is device conventional in Practical Project, and the anchored force of current anchor pole is often large not, and the destruction of anchor pole causes not due to the anchored force of anchor pole often, therefore provide the larger one of anchored force automatically to expand anchoring tooth post anchor pole just necessary.
Summary of the invention
In order to solve the hypodynamic problem of anchoring that current anchor pole exists, the utility model provides a kind of anchoring of expansion automatically tooth post anchor pole, and it is large that this expands anchoring tooth post anchor-holding force of anchor bolt automatically, and the active area of Anchor Agent is large, and it is convenient to install, and structure is simple.
The utility model solves the technical scheme that its technical problem adopts: this is automatically expanded anchoring tooth post anchor pole and comprises: the body of rod, body of rod screw thread, pointed cone head, tooth post, anchor head, rock mass; This expands anchoring tooth post anchor pole automatically a columniform body of rod, the body of rod is provided with body of rod screw thread, the front end of the body of rod is cone-shaped pointed cone head, lever front end is fitted with columniform anchor head, the centre of anchor head is provided with axial through hole, is provided with the screw thread mated with spiral thread on anchor bolt in through hole, is laterally provided with 3 ~ 30 evenly spaced pilot holes in anchor head, cylin-drical tooth post is housed in pilot hole, and tooth post can transverse shifting in the pilot hole in anchor head; During use, first the body of rod with anchor head is inserted in petrosal foramen, the body of rod is slowly continued deeply be screwed into anchor head depths, make pointed cone head outwards extrude tooth post, make tooth post outwards eject insertion rock mass, thus whole anchor pole is fixed in rock mass firmly.
The beneficial effects of the utility model are: this anchored force automatically expanding anchoring tooth post anchor pole is large, and the active area of Anchor Agent is large, and it is convenient to install, and structure is simple.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural principle schematic diagram of the present utility model.
In Fig. 1, the 1. body of rod, 2. body of rod screw thread, 3. pointed cone head, 4. tooth post, 5. anchor head, 6. rock mass.
Detailed description of the invention
In Fig. 1, a kind of anchoring of expansion automatically tooth post anchor pole, comprising: the body of rod 1, body of rod screw thread 2, pointed cone head 3, tooth post 4, anchor head 5, rock mass 6; This expands anchoring tooth post anchor pole automatically a columniform body of rod 1, the body of rod 1 is provided with body of rod screw thread 2, the front end of the body of rod 1 is cone-shaped pointed cone head 3, the body of rod 1 front end is fitted with columniform anchor head 5, the centre of anchor head 5 is provided with axial through hole, is provided with the screw thread mated with spiral thread on anchor bolt 2 in through hole, is laterally provided with 3 ~ 30 evenly spaced pilot holes in anchor head 5, cylin-drical tooth post 4 is housed in pilot hole, and tooth post 4 can transverse shifting in the pilot hole in anchor head 5; During use, first the body of rod 1 with anchor head 5 is inserted in petrosal foramen, the body of rod 1 is slowly continued deeply be screwed into anchor head 5 depths, make pointed cone head 3 outwards extruding tooth post 4, tooth post 4 is outwards ejected and inserts rock mass 6, thus whole anchor pole is fixed in rock mass firmly.
