Abstract
The utility model discloses a recoverable anchor rod with high-strength prestressing force, which is especially applicable for supporting in mining engineering and geotechnical engineering. A recoverable rod body and a non-recoverable rod body of the anchor rod are connected by screw threads, and a pin used for realizing prestressed anchorage is arranged at the thread connection part. The nut of an outer anchoring head has an integrated structure with the rod body of the anchor rod, and a counter nut or a welded nut is adopted. On the premise of not reducing the original mechanical parameters of the anchor rod, the high-strength prestressed anchorage operation of the anchor rod is realized. During the supporting process of a coal mine roadway, not only the non-uniform intensity problem of the rod body of the anchor rod is solved, but also part of the rod body of the anchor rod is recoverable and can be used for a plurality of times, thereby greatly reducing the material costs of the anchor rod, and decreasing the cost for supporting. The structure is simple, the prestressed anchorage operation is realized, the supporting effect is good, and the practicability is wide.
Description
Technical field
The utility model relates to a kind of support anchor rod, especially a kind of high-strength prestressed recoverable anchor rod that is applicable to mining engineering and geotechnical engineering supporting.
Background technology
Anchor pole is widely used in China's coal-mine roadway support at present, obtained extraordinary supporting effect, but the anchor pole in using all is disposable use, too high these two problems of support cost of support material waste and coal mine roadway have been caused, particularly in recent years along with the increasing of the coal mining degree of depth, roadway support is more and more higher to Anchoring Strength of Rock Bolts and quality requirement, the better anchor pole of higher supporting intensity and quality requirement is produced material, cause the further raising of anchor pole cost of production, aggravated the support cost expenditure of coal mine roadway.Therefore under the prerequisite that does not influence Anchoring Strength of Rock Bolts and quality, press for high-strength prestressed recoverable anchor rod,, improve the utilization rate of resource to realize that high-strength prestressed anchor pole reclaims and recycling, reduce the support cost of coal mine roadway greatly, improve the colliery economic benefit.
Summary of the invention
The purpose of this utility model is the weak point that overcomes in the prior art, provides a kind of simple in structure, and supporting power is strong, reusable high-strength prestressed recoverable anchor rod.
For achieving the above object, the technical solution of the utility model is: the recyclable body of rod of anchor pole is threaded with can not reclaiming between the body of rod, and connection of thread is provided with pin, and the end of the recyclable body of rod is provided with universal ball seat, antifriction packing ring and outer anchorage head successively.
Described outer anchorage head is made of the square toes or the six prismatic nuts that are connected as a single entity with the recyclable body of rod.
The utility model is on existing high-strength prestressed anchor structure basis, improve its syndeton, outer anchorage head adopts with anchor rod body and is linked as whole nut, is convenient to reclaim anchor pole, under the prerequisite that does not reduce the original mechanics parameter of anchor pole, realize the high-strength prestressed anchoring of anchor pole; In the colliery tunnel support process, not only solved the problem of anchor rod body intensity inequality, and can the part body of rod of anchor pole have been reclaimed, can repeatedly reuse, greatly reduce the Master Cost of anchor pole, reduced support cost.It is simple in structure, realizes prestress anchoraging, and supporting effect is good, has practicality widely.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Among the figure: anchorage head in the 1-, the 2-pin, the 3-universal ball seat, 4-antifriction packing ring, the outer anchorage head of 5-, I-can not reclaim the body of rod, the recyclable body of rod of II-.
The specific embodiment
The utility model will be further described below in conjunction with the embodiment in the accompanying drawing:
Shown in the accompanying drawing, the recyclable body of rod II of anchor pole is threaded with can not reclaiming between the body of rod I, and the inner termination that can return body of rod II is a prestressed structure, and screw connection point is provided with pin 2, to realize the prestress anchoraging of anchor pole, the active support effect of performance anchor pole.The end of recyclable body of rod II is equipped with universal ball seat 3, antifriction packing ring 4 and outer anchorage head 5 successively, outer anchorage head 5 is made of the square toes or the six prismatic nuts that are connected as a single entity with recyclable body of rod II, square toes or six prismatic nuts and recyclable body of rod II can be machined directly to body, also can weld or be threaded.Outer anchorage head 5 just with the stirring and the recovery of anchor pole; The interior anchorage head 1 of anchor pole is fried dough twist structure or non-fried dough twist structure, helps agitating resin; Anchor rod body is except that the part of interior anchorage head 1 usefulness resin anchoring is not recyclable, and other parts are all recyclable and can reuse.
Claims (2)
