Background
In China, coal mine stoping roadways are supported by metal anchor rods and anchor cables, but when stoping is carried out on a working face, accidents that people are injured by throwing out the rod bodies in the process of cutting the metal anchor rods by a roller of a coal mining machine; the twisted rod body left in the coal flow can block a scraper chain and scratch a belt, so that serious economic loss is caused; in addition, the metal rod body cut by the roller is easy to generate sparks, so that the possibility of coal dust and gas explosion accidents is caused; partial coal mine sites take the loose anchor rods to be drawn out in advance before stoping, but the labor intensity of workers is high, and the major potential safety hazard exists in the coal side construction operation which is not effectively supported.
The glass fiber reinforced plastic anchor rod is brittle when being cut, the fracture is not sharp, no spark is generated, the phenomena of flying out to hurt people, chain jamming and belt scratching similar to a metal anchor rod can not occur, and no spark is generated during cutting to cause explosion accidents. The glass fiber reinforced plastic anchor rod has the advantages of corrosion resistance, light weight and high strength, and is more and more widely applied to coal mines.
However, with the increasing of the mining depth of the mine, the increasing of the section of the roadway, the severe influence of strong mining and the like, the mine pressure of the roadway appears severely, and the deformation of surrounding rocks is large, so that the roadway is subjected to support failure phenomena such as the breakage of a rod body and the shearing of the tail of the rod body when the traditional common glass steel anchor rod is used for supporting, and the use of the glass steel anchor rod in a roadway with high stress and large deformation is seriously influenced.
In recent years, although the glass fiber reinforced plastic anchor rod has been developed greatly in terms of formula and production process, mechanical indexes such as ultimate tensile strength, ultimate shear strength and maximum torque of the rod body are greatly improved, but the use requirement in a high-stress environment is still not met.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a whole glass steel stock that excels in can solve current stock in use easy broken, technical problem that tensile and shear strength are not high.
The purpose of the utility model can be realized by the following technical scheme:
the integral high-strength glass fiber reinforced plastic anchor rod comprises a rod body, a nut and a tray, wherein the nut and the rod body are matched in a threaded manner; one end of the nut is provided with a shrinkage joint extending along the axial direction, the tray is sleeved on the periphery of the end of the nut with the shrinkage joint through the conical inner hole, and the other end of the nut without the shrinkage joint extends out of the tray; the nut, the tray and the rod body are arranged concentrically.
The other end internally mounted that the nut stretches out the tray has the nut reinforcing ring, the tray is close to the one end of nut reinforcing ring and has the bulge tube that becomes an organic whole, extends along the tray axial with the tray, and bulge tube internally mounted has the tray reinforcing ring.
Has the advantages that: the nut reinforcing ring and the tray reinforcing ring are respectively arranged at one end of the nut and one end of the convex pipe, so that the ultimate bearing capacity of the tray and the nut is improved, the tray and the nut are matched with each other, the rod body is not easy to break, and the purpose of high overall strength of the glass fiber reinforced plastic anchor rod system is achieved.
As the utility model discloses a technical optimization scheme, the one end that the tray has the protruding pipe is the round platform shape, and the external connection of round platform shape has a plurality of strengthening rib, and round platform shape and strengthening rib have all increased the intensity of tray for in use bearing capacity is better.
As the utility model discloses a technical optimization scheme, tray reinforcing ring and nut reinforcing ring are the metal material, and tray reinforcing ring and nut reinforcing ring inlay respectively and establish inside the one end of protruding pipe and nut, the tray reinforcing ring not with the nut contact, the nut reinforcing ring inner wall not with the body of rod contact, adopt metal preparation tray reinforcing ring and nut reinforcing ring to increase the intensity of reinforcing ring, and is not fragile in the use. Meanwhile, the reinforcing ring is prevented from damaging the glass fiber reinforced plastic rod body and the nut, so that the rod body can be in normal threaded connection with the convex pipe and the nut.
The utility model has the advantages that:
through external connection nut and the tray at the body of rod, and at the one end installation metal reinforcing ring of nut and protruding pipe, and through a compression molding when the reinforcing ring installation for the limit bearing capacity of nut and tray obtains promoting. The nut and the tray are matched with each other, so that the strength of the glass fiber reinforced plastic anchor rod system is integrally improved, the application range of the glass fiber reinforced plastic anchor rod system is expanded, and the safety is improved. The anchor rod is not easy to break in use, and the tensile and shear resistance capability is better.
