The right end set is connect with the left end of front end sliding sleeve by movable connecting rod, and the middle-end sliding sleeve is slided with front end sliding sleeve, tail end respectively
Set is spirally connected, and the outer wall of the tail end mobile jib is provided with the screw thread to match with nut, and the tail end mobile jib is spirally connected with nut, the tail
The outer wall right part of end sliding sleeve is equipped with tapered plug, the inner cavity of the umbrella-type gripping mechanism is left and right be respectively embedded into the first pull strap and
Second pull strap.
Preferably, the umbrella-type gripping mechanism includes at least three groups of gripping mechanisms.
Preferably, the tapered plug is rubber tapered plug.
Preferably, the maximum gauge of the drill bit is more than the diameter of umbrella-type gripping mechanism.
Compared with prior art, the utility model has the beneficial effects that：This practicality is according to the depth adjustment middle-end master of drilling
The quantity of bar and middle-end sliding sleeve meets the drilling of different depth with this, using umbrella-type gripping mechanism, passes through the round platform of front end mobile jib
Shape so that umbrella-type gripping mechanism is opened so that umbrella-type gripping mechanism is clamped with soil layer so that this practicality rubs with bonding for soil layer
Power becomes larger so that the pressure-bearing effect of anchor pole increases.

Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
- 4 are please referred to Fig.1, the utility model provides a kind of technical solution：A kind of assembling anchor for underground mining industry
The left end of bar, including front end mobile jib 1, the front end mobile jib 1 is bolted with drill bit 2, and the right end of the front end mobile jib 1 is bolted with middle-end
Mobile jib 8, the right end of the middle-end mobile jib 8 be bolted with tail end mobile jib 9, the front end mobile jib 1, middle-end mobile jib 8, tail end mobile jib 9
Outer wall is sequentially installed with umbrella-type gripping mechanism 3, front end sliding sleeve 4, middle-end sliding sleeve 5, tail end sliding sleeve 6 and nut 7 from left to right, described
The right end of umbrella-type gripping mechanism 3 is connect with the left end of front end sliding sleeve 4 by movable connecting rod 10, the middle-end sliding sleeve 5 respectively with
Front end sliding sleeve 4, tail end sliding sleeve 6 are spirally connected, and the outer wall of the tail end mobile jib 9 is provided with the screw thread to match with nut, the tail end master
Bar 9 is spirally connected with nut 7, and the outer wall right part of the tail end sliding sleeve 6 is equipped with tapered plug 11, the inner cavity of the umbrella-type gripping mechanism 3 is left,
The right side has been respectively embedded into the first pull strap 12 and the second pull strap 13.
Wherein, umbrella-type gripping mechanism 3 include at least three groups of gripping mechanisms, gripping mechanism is more, expansion open when and soil layer
Card node it is more, the close contact with soil layer forms bigger frictional force, and tapered plug 11 is rubber tapered plug, and the maximum of drill bit 2 is straight
Diameter is more than the diameter of umbrella-type gripping mechanism 3, avoids umbrella-type gripping mechanism 3 into being opened by resistance in boring procedure.
Operation principle：Drill bit 2 and front end mobile jib 1 are spirally connected, umbrella-type gripping mechanism 3, front end sliding sleeve 4 are mounted on front end master
Umbrella-type gripping mechanism 3 is connect with front end sliding sleeve 4 by movable connecting rod 10 by the outer wall of bar 1, and drill bit 2 is sent into turn hole, will be pacified
The part of dress pierces drilling, and as length is inadequate in boring procedure, middle-end mobile jib 8 and front end mobile jib 1 are spirally connected, middle-end sliding sleeve 5 and
Front end sliding sleeve is spirally connected 4, and after the completion of hole to be drilled, tail end mobile jib 9 and middle-end mobile jib 8 are spirally connected, tail end sliding sleeve 6 and 5 spiral shell of middle-end sliding sleeve
It connects, pushes tail end sliding sleeve 6 so that middle-end sliding sleeve 5 advances towards 2 direction of drill bit so that front end sliding sleeve 4 moves, even by activity
Extension bar 10 is so that the umbrella-type gripping mechanism 3 of connection advances towards 2 direction of drill bit, because front end mobile jib 1 is in circle close to the part of drill bit 2
Mesa-shaped so that 3 forced expansion of umbrella-type gripping mechanism opens, and the first pull strap 12,13 stress of the second pull strap make umbrella-type clamping
Device 3 is close to the round platform part of mobile jib 1, and umbrella-type gripping mechanism 3 is in close contact with soil layer, and the elasticity of the second pull strap 13 is less than the
The elasticity of one pull strap 12 so that the part that umbrella-type gripping mechanism 3 is located at the second pull strap 13 is not easy loosely, to pass through rotating nuts
7 so that nut 7 is contacted with tail end sliding sleeve 6 so that tail end sliding sleeve 6 can not retreat, and multigroup middle-end sliding sleeve 5 and middle-end mobile jib 8 is arranged
Meet the drilling installation requirements of different depth.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is appreciated that can these embodiments be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaiied
