Description
Technical field
A kind of coal wall caving anchor pole supplementary anchorage device is the utility model is related to, belongs to coal wall caving anchorage technology field.
Background technology
Wall caving, refer to mine operation face, tunnel side wall deforms under action of underground, the phenomenon destroyed and come off.Roof fall
It is that top plate is out of control and phenomenon of voluntarily inbreak, the two often occurs simultaneously, and often human casualty accident occurs simultaneously in both, is referred to as emitting
Top flat is helped.The cave-in accident occurred suitable for mine, underground mining, driving and other tunnelings.
At present, the effective ways for preventing coal wall caving are to carry out anchoring setting using anchor pole, i.e., carry out supporting using anchor pole
Set, anchor pole there are the types such as wood bolt, anchor metal, cement grouted bolt and resin anchor at present.For metal inverted wedge type anchor rod, its
It is made up of the body of rod, fixed wedge, activity reverse wedge, backing plate and nut.Reinforcing bar or arope creep bar are divided into reinforced concrete anchor again
Bar and arope creep bar.Metal inverted wedge type anchor rod can be good at improving the anchoring property of anchor pole, still, if anchoring is deep
Degree is longer, and key-like structure is relatively difficult to stretch into drilling, therefore, starts setting up the anchoring cartridge coordinated with anchor pole later, still,
Current anchoring cartridge is relatively simple for structure, only sets the structures such as corrugated profile, so, when in use, after anchor bolt grouting,
Reliability cannot be guaranteed between slurries and anchoring cartridge, accordingly, it is difficult to ensure the anchoring effect of wall caving, still easily occur rib by
The phenomenon of power sliding, in turn results in the danger of wall caving.
The content of the invention
The utility model is directed to existing technical problem, there is provided a kind of coal wall caving anchor pole supplementary anchorage device, it is therefore an objective to
The anchoring effect of anchoring cartridge is improved, the generation of wall caving is prevented, intends to solve the problem of prior art is present.
To achieve the above object, the utility model provides following technical scheme：A kind of coal wall caving anchor pole piggy-back anchor is fixedly mounted with
Put, it includes anchoring cartridge and anti-loose spot, it is characterised in that described anchoring cartridge is T-type structure, the central through hole of the anchoring cartridge
For the internal thread hole coordinated with threaded anchor rod, the welded anti-loose spot for being provided with wedge shape, described on the outer wall of the anchoring cartridge
Anchoring cartridge is radially provided with multiple slip casting intercommunicating pores, and note is provided between the drilling on described anchoring cartridge and coal wall caving
Hole is starched, the anti-loose spot is stretched into slip casting and set after slip casting, and anchor pole lock nut, the anchor pole lock nut are provided with the outside of the anchor pole
It is locked on the lateral surface of anchoring cartridge.
Further, preferably, the one side that the anchor pole lock nut contacts with the anchoring cartridge is spherical.
Further, preferably, the lozenges of described anti-loose spot is set towards rib bore inner.
Further, preferably, the anchoring cartridge is radially provided with least six drilling, and each drilling is along circle
All arrays are set.
Compared with prior art, the beneficial effects of the utility model are：
The utility model can cause anchoring cartridge to be well fixed in drilling by setting anti-loose spot, moreover, anchoring cartridge
Length can be less than rock-bolt length, and slip casting intercommunicating pore is provided with anchoring cartridge, can be filled in slurries by slip casting
In slip casting intercommunicating pore, so, anchoring cartridge will form an entirety with the slip casting in drilling, realize the anchoring to rib.
