Abstract
The utility model discloses a flexible metal anchor rod which comprises a metal rod head, an inner rubber shell, an outer metal shell, channel steel, a base plate, a locking tool and an air inflation valve. The inner rubber shell is tightly embedded into the outer metal shell, the channel steel is in close contact with the base plate and is firmly fixed through the locking tool, compressed air enters the inner rubber shell through the air inflation valve at the tail portion of the anchor rod, and the inner rubber shell is expanded through air inflation and then form a whole support with the outer metal shell, and the whole support plays a role in flexible support. Flexibility and compressive strength of the flexible metal anchor rod are increased, the load-carrying property for anchoring rock masses is improved, and the flexible metal anchor rod has high adaptability for dynamic pressure roadways.
Description
Technical field
The utility model relates to colliery tunnel support field, especially a kind of flexible metal anchor pole.
Background technology
Bolt support is colliery economy, effective support technology.Compare with shed ding support, bolt support has significantly improved supporting effect of roadway, has reduced roadway support cost, has alleviated labor strength, has improved operating environment, has greatly simplified coal-face end support and advance support technique, has guaranteed safety in production.The anchor pole that coal mine roadway is conventional has wood bolt, steel anchor rod, cement grouted bolt, resin anchor, pipe-seam type anchor rod, grouted anchor bar and anchor metal etc., these anchor poles are main mainly with rigid protection greatly, shortage is to the fitness of surrouding rock deformation and suppleness, be difficult to rock stratum migration to carry out anchoring adjustment timely and effectively, easily cause anchored force to decline, strength and stiffness reduce, and cause anchor pole to lose efficacy.
Summary of the invention
The utility model is intended to overcome the defect of prior art, and the novel anchor rod of a kind of simple to operate, flexible support, safety and stability is provided.
For achieving the above object, the technical solution adopted in the utility model is as follows: described flexible metal anchor pole, consists of metal club head, rubber inner casing, metal shell, channel-section steel, backing plate, lockset and charging valve.Described rubber inner casing is closely embedded in metal shell, described channel-section steel and backing plate close contact, and fixedly secure by lockset, compressed air enters in rubber inner casing by the charging valve of anchor pole afterbody, it is whole that rubber inner casing after inflation and metal shell form supporting, the effect of performance flexible support.
According to described flexible metal anchor pole, described rubber inner casing is closely embedded in metal shell, and rubber inner casing and metal shell form anchor rod body.
According to described flexible metal anchor pole, described channel-section steel and roadway surrounding rock surface close contact, outside channel-section steel, additional backing plate, fixedly secures by lockset.
According to described flexible metal anchor pole, compressed air is inflated to rubber inner casing by the charging valve of anchor pole afterbody, and lockset firmly pins rubber inner casing and metal shell after inflation, forms flexible support whole, performance anchorage effect.
Compared with prior art, the beneficial effects of the utility model are: increased suppleness and the compressive strength of anchor pole, improved the load-carrying properties of Bolted Rock Masses, workings subject to dy namic pressure is had to stronger compliance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In Fig. 1, metal club head 1, rubber inner casing 2, metal shell 3, channel-section steel 4, backing plate 5, lockset 6 and charging valve 7.
Fig. 2 is the structural representation that bolt anchorage is implemented in Semicircular arched tunnel.
In Fig. 2, anchor pole 8, country rock 9.
The specific embodiment
Below in conjunction with accompanying drawing, implementation process of the present utility model is described in further detail:
As shown in Figure 1, the utility model consists of metal club head 1, rubber inner casing 2, metal shell 3, channel-section steel 4, backing plate 5, lockset 6 and charging valve 7.Rubber inner casing 2 is closely embedded in metal shell 3, and rubber inner casing 2 forms anchor rod body with metal shell 3.
As shown in Figure 1, channel-section steel 4 and roadway surrounding rock surface close contact, outside channel-section steel 4, additional backing plate 5, fixedly secures by lockset 6.
During use, first anchor pole is implanted in roadway surrounding rock, then the charging valve 7 by anchor pole afterbody is filled with compressed air in rubber inner casing 2, by the consolidation of lockset 6, the rubber inner casing after inflation 2 and metal shell 3 is firmly pinned, formation flexible support is whole, performance anchorage effect.
