Description
Technical field
This utility model belongs to mine safety production technique field, and more particularly to a kind of Deep Underground tunnel power consumption subtracts rushes anchor
Lever apparatus.
Background technology
Currently, as China's coal-mine adopts deep increase, the bump that Deep Underground tunnel faces is dangerous also increasingly
Prominent, the safe working of deep rock stratum is faced with severe challenge.Anchor pole (rope) supporting is the broad form of mine roadway support, in coal
It is widely used in ore deposit roadway support.However, the function of existing suspension roof support and design only need to meet tunnel static stability rank
The requirement of section.Although the anchor pole pole stock intensity used in engineering is continuously available raising, in large mining depth mine laneway, impact to press
When anchor pole disrumpent feelings rate it is still very high, tunnel unstability situation happens occasionally.Therefore, existing deep-well suspension roof support material and technology
When in the face of impact dynamic load, substantially, this is a reality technology difficult problem for the numerous faced by coal enterprises of China to engineering unworthiness.
Before the present utility model, suspension roof support system be mainly used in resist exploitation cause enclose rock mass deformation, often
Support anchor rod includes common bolt, extensible anchor pole, pressure-relieving achor bar etc., is all by improving the intensity of anchor pole or strengthening anchor
The ductile characteristic of bar to improve the stress of supporting construction, so as to maintain stability of the roadway.But, bump is to roadway surrounding rock
Body is applied with a dynamic load, the rockbolt stress suddenly change for making script be under support work state, and anchor pole itself
Intensity and ductility are again limited, therefore anchor pole cannot withstand shocks and occur disrumpent feelings.
The content of the invention
The purpose of this utility model is that and overcomes drawbacks described above, and a kind of Deep Underground tunnel power consumption of development subtracts rushes anchor pole dress
Put.
The technical solution of the utility model is:
A kind of Deep Underground tunnel power consumption subtracts rushes anchor rod device, and which is mainly characterized by the connection anchoring of anchored end anchor pole
Terminal bolt, anchoring terminal bolt are connected with the piston rod of antivibrator, the antivibrator other end and free end bolt connection, free end anchor pole
The free terminal bolt of connection.
The anchored end anchor pole is by telescopic joint anchoring terminal bolt.
The free end anchor pole passes through telescopic joint free terminal bolt.
The antivibrator is viscous damper.
Each part is centrally located on same straight line.
Advantage of the present utility model and effect are to be sufficiently used viscous damper in terms of power consumption subtracts punching performance
Advantage, which passes through bolt and telescopic joint, simple structure with anchor pole.Can using conventional anchor (rope) support system construction method and
Technique, does not increase operation difficulty during construction, is a kind of very practical deep-well tunnel shock resistance ground pressure device, is especially suitable for deep
The strong mining area roadway support of colliery and pressure bump behavior.Anchor pole can utilize the tension and compressive property of itself to be supplied to and enclose
Rock anchor force, but anchor pole resistance to tension itself is limited, will be pulled off when yield strength is reached, and anchor pole is being rushed
When hitting load, its mechanical characteristic suddenly change, the intensity and extensibility of anchor pole itself are very limited, so can occur disrumpent feelings.And glue
Stagnant antivibrator subtracts punching effect with good power consumption when by bump, anchor pole is mutually screwed up with viscous damper, shape
Subtract into novel energy-consumption anchor rod device is rushed for Deep Underground tunnel, common opposing bump effect, both effectively combine, Xiang get
Benefit is evident.Impact force action passes to piston by anchor pole in anchoring section, and piston promotes oil body to produce damping force.So, impulsive force
Viscous damper piston is translated into anchor pole acting to do work oil body, i.e., mechanical energy is converted into heat energy and distributes.By such
Process, viscous damper will play a protective role to anchor pole, and be effectively protected stablizing for country rock.
