Description
Technical field
The present invention relates to a kind of mine safety protector, especially a kind of integrated protection device launched for anchor pole avalanche and anchor nut.Belong to downhole safety protection field.
Background technology
Anchor pole is widely used in underworkings supporting, and in deep tunnel or soft rock roadway support, surrouding rock stress is often larger, and avalanche that anchor pole is disrumpent feelings and anchor nut the ejection phenomenon that comes off happen occasionally, and the personal safety to underground work personnel causes great threat.Existing means of defence has following several classes：1）Rope is wrapped on termination point of anchor rod, is fixed on the wire netting of both sides；2）Termination point of anchor rod increase nut preventing and treating anchor nut ejection；3）Protected using sleeve plus rope.Can only the disrumpent feelings ejection of single protective mooring rod or anchor nut ejection more than existing protector, it simultaneously disrumpent feelings to anchor pole can not launch and anchor nut ejection is protected, and existing protection is generally to prevent anchor pole avalanche and anchor nut to launch in the way of limiting fixation, protector is highly vulnerable to breakage when anchor pole or anchor nut accumulation large energy, underground pedestrian is easily injured.
The content of the invention
In order to solve the protection question of the disrumpent feelings avalanche of anchor pole and anchor nut ejection, the invention provides the integrated protection device that a kind of anti-anchor pole avalanche and anchor nut are launched.
A kind of integrated protection device launched for the anti-anchor pole avalanche in underground and anchor nut, including rubber shock-absorbing piece, protective nut, cushion pad, preventing rubber termination, fixed rope part, expansion bolt.
Rubber shock-absorbing piece is the disk of perforate in the middle part of quality of rubber materials, and its middle part opening diameter is consistent with bolt diameter, and outer dia is more than anchor nut external diameter.
Protective nut is the nut that one end is closed, and protective nut screw thread can coordinate with anchor pole；Protective nut is inserted in end external diameter and is slightly larger than anchor nut external diameter, and protective nut blind end external diameter, which is more than anchor pole external diameter and is less than, is inserted in end external diameter；It is inserted on the outside of end to be provided with to be no less than in four and symmetrical retainer ring, retainer ring and is connected with fixed rope part, symmetrical retainer ring can ensures to fix tension uniform of the rope part to protective nut.
Cushion pad is one section of quality of rubber materials cylinder, and body diameter is less than protective nut internal diameter.
Fixed rope part is combined by one section of high-strength spring and steel wire rope and clamping rings.Fixed rope part one end is high-strength spring, and high-strength spring end is connected with high strength wire rope, and high strength wire rope end is respectively connected with clamping rings, and clamping rings is the annulus steel disc provided with connecting hole.High-strength spring can make to fix rope part in original state is in tension, and certain elastic deformation space can be provided when protector is moved along anchor pole direction and buffering energy-consumption effect is played.
Preventing rubber termination is divided into fixing end and anticollision end.Fixing end is one section of hollow rubber sleeve, and its internal diameter always, can be fastened on its outside with protective nut blind end external diameter, and its external diameter is inserted in external diameter more than protective nut；Anticollision termination is hollow ellipsoids, and steam vent is provided with spheroid, and exhaust pressure relief when can be collided in anticollision termination prevents explosion；Reflecting strips are provided with the outside of anticollision end, workman can be made to find when walking at anchor pole protrusion, are avoided in time, are flexible contact when preventing rubber termination can make one to contact with termination point of anchor rod, play a part of protecting tunnel pedestrian.

Embodiment
The present invention is further detailed explanation with reference to the accompanying drawings and detailed description.
The invention provides the integrated protection device that a kind of anti-anchor pole avalanche and anchor nut are launched, including rubber shock-absorbing piece 4, protective nut 5, fixed rope part 6, preventing rubber termination 7, cushion pad 10, expansion bolt 11.
As shown in figure 1, apparatus of the present invention application method is as follows：（1）Rubber shock-absorbing piece 1 is enclosed on anchor pole and against nut；（2）Cushion pad is placed in protective nut and on anchor pole, protective nut retains certain distance away from rubber shock-absorbing piece；（3）Fixing hole is bored near anchor pole, expansion bolt is put into fixing hole, the clamping rings of fixed rope part is enclosed on expansion bolt, expansion bolt nut is tightened；（4）Preventing rubber termination is arranged on protective nut blind end.
The preventing principle launched nut：When generation nut is launched, nut promotes rubber shock-absorbing piece to bump against with protective nut first, and rubber shock-absorbing piece plays a part of abatement noise when nut and protective nut are collided and damping is consumed energy；Protective nut is tightened against on anchor pole, can stop that nut ejects anchor pole；When nut kinetic energy is larger, destroys the threaded connection between protective nut and anchor pole, the high-strength spring for the fixation rope part being connected with protective nut can be deformed and absorb part impact energy, and play resistance consumption effect to the motion of anchor nut and protective nut；When whole protector is destroyed, bumper and absorbing shock is played a part of in preventing rubber termination in protector and people or underground equipment collision, while it can increase air drag, further consumes the kinetic energy of nut and protector.The present invention has multistage protection function for the nut ejection in high surrouding rock stress tunnel.
To the disrumpent feelings avalanche preventing principle of anchor pole, when anchor pole disrumpent feelings generation avalanche under the high surrouding rock stress in tunnel, the high-strength spring of the fixation rope part connected on protective nut can be deformed and absorb part impact energy, and play resistance consumption effect to the motion of anchor pole and protective nut；During the threaded connection that anchor pole kinetic energy is larger to be destroyed between protective nut and anchor pole, termination point of anchor rod can be first in surge guard nut rubber cushion blocks, rubber cushion blocks can produce elastic deformation and absorb part impact energy, prevent the direct impact failure protective nut blind end of termination point of anchor rod；When anchor pole kinetic energy fixes rope part or its attachment structure compared with havoc, bumper and absorbing shock is played a part of in preventing rubber termination in protector and people or underground equipment collision, while it can increase air drag, further consumes the kinetic energy of anchor pole and protector.
When patent of the present invention is used in high surrouding rock stress tunnel, effective integrated protection can be carried out to anchor pole avalanche and nut ejection, especially there is multistage protection function, and the present invention can be protected anchor pole avalanche and nut ejection in elastic buffer power consumption mode, the possibility that protector is totally disrupted failure is reduced, the threat of anchor pole avalanche and nut ejection to safety in production is greatly reduced.The present invention is simple in construction, it is easy to installs, dismantle, safe and reliable, and repeatable utilization.
