Description
Technical field
The utility model is related to mine support field, more particularly to a kind of spiral connection left-right rotary assembly type anchor pole.
Background technology
At present in the live rockbolt installation of mine timbering, most of anchor pole used is left-handed anchor pole or dextrorotation anchor
Bar, and two kinds of rockbolt installations and have obvious advantage and disadvantage when using.When dextrorotation anchor pole is installed, because body of rod screw thread is dextrorotation, adopt
When rotating body of rod agitating resin Anchor Agent with conventional rig, right-handed thread has the power for screwing out Anchor Agent out of hole, it is impossible to have
Densification Anchor Agent is imitated in foot of hole, anchoring effect is influenceed；But dextrorotation anchor pole is good to prop surface adaptability, nut can edge
Body of rod total length is rotated, and effective anchoring can be realized to prop.When left-handed anchor pole is installed, rig rotation body of rod agitating resin Anchor Agent
When, left hand thread has the power that will be pushed away in Anchor Agent, can make Anchor Agent and the closely knit bonding of the body of rod, make anchoring reliably abundant, if but
After drilling, due in rock mass the stress of primary rock destroyed, cause institute's drilling inter collapse, cause left-handed anchor pole not go deep into
Predetermined rock mass depth, then occur that pretension screw thread can not be stretched into hole, causes that pretightning force can not be applied；Also due to tunnel surface
Rock mass is disturbed in punching and produces loosening and drop, and causes anchor rod pallet board protection zone to be recessed, can not equally apply
Enough pretightning forces can not apply pretightning force completely.Based on above-mentioned situation, in the urgent need to a kind of cost is low, it is simple to install, operation
Easy has left-handed anchor pole and the novel anchor rod of dextrorotation anchor pole advantage, while the anchor force of anchor pole is ensured, improves anchor pole
Installation effectiveness, construction effect, greatly improve the reliability of suspension roof support, it is ensured that the safety in supporting region.
Utility model content
Content of the present utility model is to propose a kind of spiral connection left-right rotary assembly type anchor pole, and the utility model passes through a left side
The bolt for revolving anchor pole segment trailer is connected with the nut groove screw-in of dextrorotation anchor pole section end, and pallet passes through anchor pole spiral shell with the dextrorotation body of rod
Parent phase connects, and the removable two parts that are divided into of anchor pole can be readily transported during underground transportation by reaching, when underground is installed, and left-handed anchor pole section is being bored
When resin anchoring agent is stirred brokenly in hole, left hand thread, which can be produced, can compress the power of Anchor Agent, so as to increase the close of Anchor Agent
Solidity, and the anchor force for ensureing suspension roof support is realized, anchor nut can be always screwed into along the body of rod of dextrorotation anchor pole section, and it is to branch
Watch box surface applies pretightning force and not limited by reach, it is ensured that can apply enough pretightning forces.To achieve these goals,
The utility model is adopted the following technical scheme that：
A kind of spiral connects left-right rotary assembly type anchor pole, including：
The left-handed anchor pole section of strap bolt, dextrorotation anchor pole section, metal tray and anchor nut with nut groove, the band spiral shell
The left-handed anchor pole section of bolt passes through left-handed anchor pole segment trailer bolt and dextrorotation anchor pole section with the dextrorotation anchor pole section with nut groove
End nut groove, which is screwed in, to be connected, and pallet is matched with the dextrorotation body of rod by nut.
Preferably, the left-handed anchor pole section is indulged muscle screw-thread steel by left-handed nothing and made, and left-handed anchor pole segment trailer be processed into
The bolt that the nut groove of dextrorotation anchor pole section matches, wherein bolt surface rolling has right-handed thread.
Preferably, described dextrorotation anchor pole section is made by dextrorotation without vertical muscle screw-thread steel, and dextrorotation anchor pole section end is processed into
The rolling of the nut groove matched with left-handed anchor pole segment trailer bolt, wherein nut groove inner surface has right-handed thread, body of rod table
Face rolling has dextrorotation full thread.
Preferably, the bolt of the left-handed anchor pole segment trailer can be screwed in the dextrorotation anchor pole section end nut groove.
Preferably, the pallet is fixed in the dextrorotation anchor pole section with the dextrorotation body of rod by the anchor nut,
And anchor nut can retreat along dextrorotation anchor pole section body of rod whole process.
Compared with related anchor pole, the utility model has the following advantages that：
The spiral connection left-right rotary assembling anchor pole that the utility model is addressed, left-handed anchor pole section, band nut with strap bolt
Dextrorotation anchor pole section, metal tray and the anchor nut of groove, each structure member are compact, reasonable in design, and dismounting, installation are simple；It is left
Rotation anchor pole segment trailer is processed into the bolt supporting with the nut groove of dextrorotation anchor pole section end；It is processed into dextrorotation anchor pole section end
For the nut groove with the bolt matching of left-handed anchor pole segment trailer；Left-handed head screws in nut groove with the dextrorotation body of rod by bolt
It is connected, ensures anchor rod strength, can be good at adapting to stress state complicated in drilling；When underground is installed, by left-handed anchor pole section
Bolt screw in the nut groove of dextrorotation anchor pole section, left-handed anchor pole section is after resin anchoring agent is stirred brokenly, and left hand thread can produce pressure
Be tight compact the power of Anchor Agent, is conducive to increasing the compactness of Anchor Agent, it is ensured that the anchor force of anchor pole；Anchor nut can be along dextrorotation bar
Body is screwed into always, is not limited by body of rod reach, the complex situations in the metapore and aperture that preferably adapted to drill.Each knot
Structure part production cost is low, and anchor pole transportation safety, simple and convenient assembly, coordinates eventually through each member in tight and realizes in guarantee anchor pole
Anchor force while, improve rockbolt installation efficiency, construction effect, greatly improve the reliability of suspension roof support, it is ensured that supporting area
The safety in domain.
