Abstract
The utility model relates to a locking nut for support and protection of a bolt, which is used in mine drifts. The utility model comprises a nut body with a threaded hole. The shape of the nut body is orderly composed of a hemisphere-shaped body, a hexagonal cylinder which is connected with a circular plane of the hemisphere-shaped body, and a cylinder connected with the other face of the hexagonal cylinder. A locking ring is arranged at the inner hole position of the connection of the cylinder and the hexagonal cylinder. When the nut which is matched with an aligning tray of the bolt is used for support and protection of the bolt in the mine drifts, the nut has four functions of aligning center, high strength, quick installation, and anti-loosing, so the nut can cause the bolt to bear a reasonable force and to exert carrying capacity, can enhance the effect of supporting and protecting in the mine drifts and excavating speed, and simultaneously is convenient for using and managing parts.
Description
The locking nut that a kind of mine working bolt support that the utility model relates to is used.
At present, the development of mine working bolt support technology is very fast, common six square nuts the incompatibility bolt support about the aligning function, a requirement such as high strength and Fast Installation, for addressing these problems, all taked some new measures both at home and abroad, as: for improving the aligning function, better meet the requirement that anchor pole tilts to install, between anchor pole pallet and six square nuts, add a center-adjusting pad; For solving the requirement that increases intensity, use high strength six square nuts instead by common six square nuts; For solving the anchor pole Fast Installation, on the basis of six square nuts, install a clamp ring or pin additional with topic.These measures have certain positive role, and still, not enough is to have increased part than in the past, has also strengthened the trouble of using and managing.
The purpose of this utility model is to provide a kind of high strength locking nut that integrates above-mentioned functions.
The purpose of this utility model can reach by following measure.This nut with internal thread through hole, its outer shape is made up of three parts, is followed successively by half sphere shape and the hexagonal prism body that links to each other with the circular flat of half sphere shape, and the cylinder that is connected in hexagonal prism body another side; Junction endoporus at cylinder and hexagonal prism body is provided with clamp ring.Because the spherical of half sphere shape can correspondingly with the spherical recess on the anchor pole aligning pallet that uses that matches play the aligning effect; And hexagonal prism body and half sphere shape are integrated, and are equivalent to special high nut, have increased the bearing strength of screw thread; Clamp ring then can provide a stable moment of torsion.
Compared with prior art, the advantage that the utility model had is conspicuous:
1, this nut structure novelty, one can replace center-adjusting pad and two parts of high strength quick mounting nut, and the scene is used and managed all very big benefit.
2, the function of this nut is many, the collection aligning, and high strength, Fast Installation and locking four functions are in one, and it can simplify the anchor pole installation procedure, accelerates installation rate, and then improves tunnelling speed; By the aligning effect, can eliminate the additional bending stress of anchor pole afterbody, make anchor pole stressed rationally, give full play to the supporting effect that supporting capacity improves the tunnel.
Accompanying drawing 1 is a normal cross-section view of the present utility model.
As shown in drawings, this nut body with internal thread through hole, its outer shape is made up of three parts, is followed successively by half sphere shape and the hexagonal prism body that links to each other with its circular flat, and the cylinder that is connected in hexagonal prism body another side; Interior hole site in cylinder and hexagonal prism body junction is provided with clamp ring.Half sphere shape 1 be with anchor pole aligning pallet on spherical recess cooperated the aligning effect.Usually the little 0.5-4mm of radius of the spherical recess on this spherical radius ratio anchor pole aligning pallet can eliminate the additional bending stress of anchor pole generation when vertical with tray bottom surface, makes anchor pole keep rational stress; Hexagonal prism body 2 comes down to six square nut, it be connected with half sphere shape 1 as a whole after, its core reach has increased, become a kind of special high nut (its thickness is not less than 35mm) of special thickening, can bear bigger load and do not thread off than common six square nuts (under the situation of same material); Clamp ring 3 usefulness special plastics are made, and use the method for punching press to embed the endoporus place that hexagonal prism body 2 links to each other with cylinder 4, can play anchor pole Fast Installation and locking effect.The thickness of clamp ring is 3mm-7mm, and its internal diameter is than the little 1-3mm of internal diameter of screw.The aperture of cylinder 4 should be greater than the external diameter of nut inner thread, and the external diameter of cylinder 4 then should be less than the inscribed circle diameter of coupled hexagonal prism body 2, the operation when not hindering nut check.This nut matches with anchor pole aligning pallet when using, alternative center-adjusting pad and quick mounting nut or two parts of common six square nuts, and have aligning concurrently, high strength, Fast Installation and locking four functions, guarantee that anchor pole is stressed rationally, realize Fast Installation, improved bolt support quality and tunnelling speed.
Claims (4)
1, a kind of locking nut that is used for the mine working bolt support, comprise nut body with internal thread through hole, it is characterized in that, the outer shape of this nut is made up of three parts, be followed successively by half sphere shape and the hexagonal prism body that links to each other with its circular flat, and the cylinder that is connected in hexagonal prism body another side; Interior hole site in cylinder and hexagonal prism body junction is provided with clamp ring.
2, locking nut as claimed in claim 1 is characterized in that, the thickness of above-mentioned nut is more than or equal to 35mm.
