Description
Technical field:
The security appliance field that the utility model relates to use in coal mine, particularly a kind of coal mine anchor rod protective case.
Background technique:
The lengthy procedure that supporting coal mine underworkings experienced wooden support, build arch supporting, fashioned iron supporting to suspension roof support, state
It is inside and outside that it was verified that suspension roof support has, anchorage depth is big, lower part unstable formation is anchored in the rock stratum of upper stabilizer,
The advantages of supporting good reliability.Suspension roof support can apply prestressing force, realize quick, active support, therefore be tunnel economy, effective
Support form, be widely used in supporting coal mine underworkings.
Suspension roof support is installed according to array pitch between design, due to underground coal mine complex geologic conditions, crustal stress or is adopted
It is dynamic to influence often to occur, therefore the driving face of suspension roof support, two lane of fully-mechanized mining working, occasional is because of extremely abnormal original
Thus anchor rod body is caused to break, nut skid-falling situations such as, worker during this environmental work there are great security risk,
Even there is human casualty accident.
Since the probability that anchor pole breaks, nut skid-falling occurs is minimum, and not ready-made security protection method, it is general
All over not taking counter-measure.The safety measure that a small number of coal mines are taken is using the iron wire not less than 12# at the end that anchor pole exposes
Head is wound, and is then attached on reinforced mesh.
The shortcomings that prior art:
1. ascending a height operation in underground site, winding of the iron wire in the exposed end of anchor pole (about 50mm) is more difficult；
2. anchor pole winding iron wire not only occupies a large amount of working time, personnel stand bind on ladder for a long time, safety wind
Danger greatly improves, or even the worker having has grown finger and also often punctured by iron wire the binding time；
3. tunnel anchor pole uses iron wire take-up strap, iron wire consumption is very big, and winding needs to put into more people
Power, material, artificial economic cost are higher；
4. the iron wire of take-up strap is easy to that protection is caused to fail by aqueous corrosion in water drenching region.
Utility model content:
Purpose of the utility model is to solve the deficiencies in the prior art, provide a kind of coal mine anchor rod protective case.
The technical solution adopted in the utility model are as follows:
A kind of coal mine anchor rod protective case, including anchor pole, Supporting plate for anchor and for the steel wire of protection, it is characterised in that:
The anchor pole end is equipped with external screw thread and is screwed with nut, and anchor pole passes through Supporting plate for anchor, Supporting plate for anchor is located at nut
Top；
Anchor pole lower end protrudes from nut and is threaded onto a tapped anchor pole protective case, and anchor pole protection body passes through
There is steel cable, the both ends of wirerope are respectively connected with an anti-drop hook；
The upper surface of Supporting plate for anchor contacts steel wire, and anti-drop hook hook is on steel wire.
Preferably, the outer wall of anchor pole protective case is cased with plastic protective sleeve, soft elastic material is made.
Preferably, being equipped with axial through hole inside anchor pole protective case, the internal screw thread of anchor pole protective case runs through positioned at this
The upper half in hole.
Preferably, the central axes of through hole are overlapped with the central axes of anchor pole protective case, steel wire penetrating anchor pole protective case
And through hole.
Preferably, the both ends of wirerope pass through tapered end aluminium set and tapered end collar-shaped into steelwire sleeve, steelwire sleeve is worn
Cross anti-drop hook.
Compared with prior art, the utility model has the beneficial effects that:
(1) tunnel can be effectively prevented to press etc. anchor pole caused by reasons break, the possible safe thing of nut skid-falling
Therefore it is practical；
(2) wirerope-winding knots slightly loose fixation, can make anchor pole when abnormal formation stress, downward
Active force is buffered because tightening wirerope, is reduced；The biggish breaking load of wirerope can effectively solve the problem that anchor pole reinforcing bar collapses
Disconnected or nut skid-falling and issuable casualty accident；The plastic protective sleeve being arranged outside protective case can under special circumstances (Gu
Determine wirerope to be pulled off), the extent of injury to personnel is reduced in a manner of flexible impact；
(3) mode for replacing iron wire binding, had not only improved breaking load ability, but also enhance corrosion resistance；
(4) anti-drop hook keeps wirerope fixed safer reliable；Tapered end lantern ring increases the bending radius of wirerope, keeps away
Exempt from wirerope and is excessively bent the damage caused by wirerope；Rope end is withheld using tapered end aluminium set, makes rope end in big active force
Under, it can effectively prevent slipping；
(5) protective case installation procedure is simple, swift and convenient to operate, time saving and energy saving, and the labour that can substantially reduce personnel is strong
Degree reduces about 5 times of human input, shortens ascending a height the activity duration for construction personnel, security risk risk substantially reduces；
(6) it is scrapped when not used in tunnel, anchor pole protective case can recycle, and realize and be recycled.
Detailed description of the invention:
Fig. 1 is the using state structure diagram of the utility model；
Fig. 2 is the schematic view of the front view of the utility model；
Fig. 3 is the partial enlargement structural representation in the utility model Fig. 1 at A.
Specific embodiment:
