Description
Technical field
The utility model relates to anchor apparatus field, being specifically related to is a kind of slope in the range of barrel
The anchor structure that body is reinforced.
Background technology
There is the unstable problem that rock fracture is grown in small-clear-distance tunnel, the expansion type anchor traditional when construction
Bar is often difficult to be fixed, and common way is after deep hole beaten by employing windlass, then irrigates anchor in anchor hole
Gu glue, until inserting anchor pole after one minute, owing to the anchor adhesive in now bolthole is already at most preferably again
Half coagulated state, be more more difficult to into toward interpolation, the problem of most critical be due to rock fracture grow shakiness
Fixed characteristic, some detritus withdrawn from hole when inwall at drilling rod can sink or deform, and partly condenses in addition
Anchor adhesive so that the insertion of anchor pole is more difficult, being even inserted into half cannot insert, can only be by this anchor hole report
Useless, the even discovery having all cannot can not pulled out after inserting, and can only cut off and scrap, not only overall work
Make inefficient, and there is the most serious wasting phenomenon.
Utility model content
This utility model purpose is to provide a kind of anchor structure that Inclination body is reinforced in the range of barrel, its energy
Technical problem in the presence of effective solution background technology.
In order to solve the problem in the presence of background technology, it comprises anchor bar body 1, one end peace of this anchor bar body 1
Equipped with nut 6 and corresponding backing plate 7；The other end of described anchor bar body 1 is provided with drill bit 3, described anchor bar body
The inside of 1 competitively offers inner tube 2, is located close near drill bit 3 one end be provided with blender in this inner tube 2
4, its other end is provided with medicament district 5, and the other end in described medicament district 5 is provided with inner tube 2 of can fitting
The piston 8 that inwall slides, the other end of this piston 8 is provided with to spin and is fixed on the closing of anchor bar body 1 end
Device 9, described anchor bar body 1 radially offers the plastic hole 10 communicated with inner tube 2,10, this plastic hole
Between drill bit 3 and blender 4.
On the periphery of described anchor bar body 1, circumference offers the antiskid groove 11 of several equidistant arrangement.
Described blender 4 is helical blade.
Owing to have employed above technical scheme, this utility model have the advantages that employing by drill bit and
The anchor bar body doubling as drilling rod is integrated into the design of an overall Bullet structure, utilizes anchor bar body to bore
Hole drill bar so that it is adding the drill bit construction that can use big 2 to 4 millimeters of the diameter than anchor bar body man-hour, making
The spatial volume that must tamp between anchor bar body and hole wall is the least, and in anchor pole, can to realize anchor pole complete for the anchor adhesive of preliminary filling
Long anchoring, while simplifying installation operation, improves rockbolt stress condition, tends to reasonable, and simplify
Down-hole supporting construction operates, improves efficiency.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model, below in conjunction with accompanying drawing, embodiment is briefly described.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
For the technological means making this utility model realize, creation characteristic, reach purpose and be readily apparent from effect
Understand, below in conjunction with the accompanying drawing in this utility model embodiment, to the technology in this utility model embodiment
Scheme is clearly and completely described.
Referring to Fig. 1, this detailed description of the invention is to be achieved by the following technical solutions, and it comprises anchor bar body 1,
One end of this anchor bar body 1 is provided with nut 6 and corresponding backing plate 7；The other end of described anchor bar body 1 is provided with
Drill bit 3, the inside of described anchor bar body 1 competitively offers inner tube 2, is located close to drill bit 3 one in this inner tube 2
Being provided with blender 4 near Duan, its other end is provided with medicament district 5, the other end in described medicament district 5
Being provided with the piston 8 that inner tube 2 inwall of can fitting slides, the other end of this piston 8 is provided with to spin and is fixed on
The sealer 9 of anchor bar body 1 end, described anchor bar body 1 radially offers the plastic hole communicated with inner tube 2
10, this plastic hole 10 is between drill bit 3 and blender 4.
On the periphery of described anchor bar body 1, circumference offers the antiskid groove 11 of several equidistant arrangement, is punching
After one-tenth, can be suitable tap anchor bar body 1 by iron hammer, make rock loose at anchor hole inwall sink automatically
Block antiskid groove 11, add anchor adhesive and be greatly improved the anchoring strength of entirety.
Described blender 4 is helical blade, the resin anchoring medicament that has flow through can be played stirring action,
Greatly add intensity when combining.
Owing to this detailed description of the invention entirety uses, drill bit 3 and the anchor bar body 1 doubling as drilling rod are integrated into one
The design of overall Bullet structure, utilizes anchor bar body 1 to make boring drilling rod so that it is permissible adding man-hour
Use and construct than the drill bit 3 of big 2 to 4 millimeters of the diameter of anchor bar body 1, must fill out between anchor bar body 1 and hole wall
Real spatial volume is the least, and in anchor pole, the anchor adhesive of preliminary filling can realize anchor pole full length fastening, executes simplifying installation
While work operation, improving rockbolt stress condition, tend to reasonable, anchor pole is no need for again after punching enters
Extract；When constructing complicated or broken rock stratum, because using anchor bar body 1 directly to hole, boring puts in place
After, sealer 9 can be opened and promote piston 8 directly to anchor, it is ensured that anchor pole is complicated or broken
Installation quality in rock stratum, and simplify down-hole supporting construction operation, improve efficiency.
Last it is noted that above example is only in order to illustrate the technical solution of the utility model, rather than right
It limits；Although this utility model being described in detail with reference to previous embodiment, this area common
It will be appreciated by the skilled person that the technical scheme described in foregoing embodiments still can be modified by it,
Or wherein portion of techniques feature is carried out equivalent；And these amendments or replacement, do not make corresponding skill
The essence of art scheme departs from the spirit and scope of this utility model each embodiment technical scheme.
