Description
Technical field
The utility model relates to mining exploitation support apparatus technical fields, more specifically, being related to a kind of country rock anchor pole guarantor
Protection unit.
Background technique
With being continuously increased for coal demand, domestic many coal mines all enter deep resource successively and exploit, great burying, height
Crustal stress, supporting condition complication are the inevitable development trend of colliery tunnel support.It is special in fault tectonic band or high-ground stress
It is the difficult complex condition such as deep soft rock roadway with large deformation, rock deformation is very big, and ground pressure shows strongly, existing supporting material
Expect that intensity is low, poor ductility, be unable to suitable for surrounding rock deformation, the phenomenon that large area anchor pole fracture failure occurs, seriously affect mine
Safety in production.For this phenomenon, most domestic coal mine is mentioned using increasing support material specification, improving the methods such as material
The mechanical property of high anchor pole, Enhanced support constrain surrouding rock deformation, not only greatly increase support cost, but also anchor pole is pulled off
Phenomenon is it is possible to can not contain.
Utility model content
The purpose of the utility model is to provide a kind of country rock anchor pole protective device, which can be improved traditional country rock anchor
The phenomenon that intensity and toughness of bar, reduction country rock anchor pole fracture failure, the service life of country rock anchor pole being extended, safety is good,
Support cost is low.
To achieve the goals above, the technical solution adopted in the utility model is as follows：
A kind of country rock anchor pole protective device, including mounting plate, the mounting plate outside are equipped with steadying plate, the mounting plate
It is mounted on country rock anchor pole, is set on the mounting plate there are three mounting hole, described three are installed by outside bolt sleeve with steadying plate
It is machined with oblique screw thread inside hole distribution triangular in shape and each mounting hole, is set on the inside of the mounting plate there are three support threaded post,
Three support threaded posts screw in inside mounting hole, and each support threaded post end is equipped with pressing plate, the pressing plate and country rock side
Contact, the mounting plate inside country rock anchor pole are equipped with support sleeve, and the support sleeve is respectively held against three by elastic link
Threaded post is supported, several anti-items that sprain are equipped between the support sleeve and mounting plate.
Further, elastic stability column is equipped with mounting plate upper installing hole corresponding position on the steadying plate.
Further, anti-skidding cushion is equipped between the pressing plate and country rock.
Further, the anti-both ends that sprain are snapped connection with support sleeve and mounting plate respectively.
Compared with the prior art, the beneficial effects of the utility model are as follows：
The utility model cooperates other component using the support threaded post of distribution oblique and triangular in shape, can receive in country rock
To immense pressure, when will tend to deformation, threaded post and the equal stress extruding of support sleeve is supported to be compressed, offset country rock anchor pole by
Radial pressure, avoid the premature failure of country rock anchor pole, while the deformation tendency of country rock can also be inhibited, the cooperation of slanting structure is anti-
Sliding cushion and steadying plate can improve stress deformation surplus, further increase the device while protecting country rock anchor pole
Reliability.
