Abstract
The utility model relates to a kind of high anchored force recoverable anchor rod, comprise: can not exhausting section, main rod body, pallet, nut, can not exhausting section and main rod body be threaded by linking, can not be provided with external screw thread in exhausting section surface, main rod body upper end is provided with pallet and nut.The beneficial effects of the utility model are: structure is simple, easy for installation; Can improve higher anchored force, supporting effect is good; Anchor pole can realize partially recycled after use terminates, and saves support cost.
Description
Technical field
The utility model relates to a kind of high anchored force recoverable anchor rod, belongs to mine support equipment technical field.
Background technology
At present, mine often uses anchor pole to reinforce roadway surrounding rock, but common anchor pole is single use, which results in the waste of support material, considerably increases support cost; Simultaneously along with the continuous increase of mining depth, the requirement of mine to anchor-holding force of anchor bolt is also more and more higher, and common anchor pole cannot meet the demands.Therefore, under the prerequisite not affecting Anchoring Strength of Rock Bolts and quality, in the urgent need to a kind of high anchored force recoverable anchor rod easy for installation, to realize recovery and the recycling of anchor pole, reduce coal mine support cost.
Utility model content
The purpose of this utility model is the weak point overcoming prior art, and provide one to be convenient to install, supporting effect is good, reusable high anchored force recoverable anchor rod.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of high anchored force recoverable anchor rod, comprising: can not exhausting section, main rod body, pallet, nut, and can not exhausting section and main rod body be threaded by linking, can not be provided with external screw thread in exhausting section surface, main rod body upper end is provided with pallet and nut.
Described can not exhausting section end be taper head.
The described external screw thread degree of depth is 12.5 ~ 15mm, and pitch is 20 ~ 25mm.
Described main rod body is the high strength glass fiber reinforced plastic body of rod.
Therefore, the beneficial effects of the utility model are: structure is simple, easy for installation; Can improve higher anchored force, supporting effect is good; Anchor pole can realize partially recycled after use terminates, and saves support cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1. can not be connected screw thread 6. external screw thread by exhausting section 2. main rod body 3. pallet 4. nut 5.
Detailed description of the invention
The technical characteristic realized to make the utility model with reach object and be easy to understand, below in conjunction with accompanying drawing, set forth the utility model further.
As shown in Figure 1, a kind of high anchored force recoverable anchor rod, comprising: can not exhausting section 1, main rod body 2, pallet 3, nut 4, can not be connected by being connected screw thread 5 with main rod body 2 by exhausting section 1, can not be provided with external screw thread 6 in exhausting section 1 surface, main rod body 2 upper end is provided with pallet 3 and nut 4.
Adopt high anchored force recoverable anchor rod of the present utility model, directly can rotate into soft-rock tunnel, be convenient to install; Can not exhausting section and country rock close contact, larger anchored force can be provided; After anchor pole use terminates, back out nut, lay down pallet, oppositely screw out main rod body, realize the partially recycled of anchor pole, thus save support cost.
Claims (4)
1. a high anchored force recoverable anchor rod, comprising: can not exhausting section, main rod body, pallet, nut, and can not exhausting section and main rod body be threaded by linking, can not be provided with external screw thread in exhausting section surface, main rod body upper end is provided with pallet and nut.
2. high anchored force recoverable anchor rod as claimed in claim 1, is characterized in that: described can not exhausting section end be taper head.
