Abstract
The utility model relates to an easy-to-recover anchor rod which is used for the bolt-spray support of underground engineering, belonging to the field of mining. The existing inverse wedged anchor rods can not be recovered for reuse. The large end of a lower wedged block is welded with a screw nut, an upper wedged block and the lower wedged block are provided with via holes, and a rod body is penetrated through the via holes to screw with the screw nut. The rod body, a tray and the screw nut can be recovered for reuse after the easy-to-recover anchor rod is utilized.
Description
A kind of easy recovery anchor pole is used for the bolt-spary supports of underground construction, belongs to field of mining.
The metal inverted wedge type anchor rod is one of anchor pole commonly used, and its structure as shown in Figure 1.It is made up of fixed wedge (1), movable wedge (2), the body of rod (3), supporting plate (4) and nut (5) etc.Fixed wedge (1) is that at an end of the body of rod, major part is at the bottom of the hole by the cast iron cast, and the afterbody of the body of rod (3) has screw thread.Movable wedge (2) also is castiron, and the microcephaly is at the bottom of the hole.During installation, movable voussoir is tied up in fixed wedge (1) bottom, together in the patchhole, fallen the afterbody of wedge with special-purpose hammer lever hammering activity then, can with anchor rod anchored in country rock, overlap upper padding plate and fastening nut at last again.The characteristics of this anchor pole are: the anchor head part is that face contacts with hole wall, and anchoring property is good, and is simple in structure, makes easily.
The deficiencies in the prior art part is: reclaim difficulty, high material consumption.
The purpose of this utility model is: it is simple to design a kind of manufacturing, is convenient to install, and easily reclaims, can be multiplexing, and both economical novel anchor rod.
Scheme of the present utility model is: be made up of nut (6), lower wedge block (7), last voussoir (8), the body of rod (3), supporting plate (4), nut (5).Nut (6) is welded on lower wedge block (7) stub end, lower wedge block has circular hole in (7), and the surface has groove (9), and last voussoir also has circular hole in (8), also there is groove on the surface, through hole from nut (6) to last voussoir (8) stub end of the inner formation in two voussoirs butt joint back.The groove on voussoir surface (9) is used to increase frictional force and is convenient to bundle, and all there is screw thread at the body of rod (3) two ends.
Feature of the present utility model is: the lower wedge block stub end has nut, in circular hole is arranged, in the last voussoir circular hole is arranged, there is groove on two voussoir surfaces, butt joint back forms a through hole from nut to last voussoir afterbody.
Fig. 1 is the schematic diagram of inverted wedge type anchor rod.
Fig. 2 is the utility model structural representation.
Below in conjunction with embodiment the utility model further is illustrated: cylinder iron pour into upper and lower voussoir, stub end at lower wedge block is welded with nut (6), circular hole has been dug in upper and lower voussoir inside, after they dock, the body of rod (3) can insert from last voussoir afterbody, pass upper and lower voussoir, on spinning with the nut of lower wedge block end, all there is groove (9) on two voussoir surfaces.During use upper and lower voussoir is held together with iron wire, in the patchhole.Use voussoir afterbody in the specialized barrel hammering then, make to produce anchored force between two voussoirs and the hole wall, two voussoirs are anchored in the country rock, screw on the body of rod (3) after, the cover mounting plate, fastening nut (5), anchor pole can play support action to country rock.Reaching after the seeervice cycle when needing (or produce), as long as unclamp nut, can disassemble most of materials such as the body of rod, supporting plate, nut, reuse.
The utility model and inverted wedge type anchor rod are compared, and be good, simple in structure except having the anchor force performance, outside the advantage of easily making, can also reclaim the parts such as the body of rod, pallet and nut, reuses, and saved material, reduced production cost.
Fig. 2 is the specification digest accompanying drawing.
Claims (1)
1, a kind of easy recovery anchor pole is made up of upper and lower voussoir, the body of rod, supporting plate, nut, and it is characterized in that: the lower wedge block stub end is welded with nut, in the upper and lower voussoir circular hole is arranged, and the butt joint back forms through hole, and there is groove on the surface.
