Abstract
The utility model belongs to the technical field of the coal mine tunnel safety support, in particular to a whole-recovering reutilizing rock-bolt and disassembling tool. The major technique characteristics of the utility model are that it comprises a metal rod body and a sleeve sheathed with the metal rod body; the screw thread on the top of the metal rod body is sheathed with a nut which is small inside and large outside, and the bottom of the nut is provided with screw thread and is sheathed with a nut and a tray; the inner wall of the sleeve is provided with screw thread, and the top is provided with a longitudinal slot. The disassembling tool is a screw that can rotate into the sleeve. When the rock-bolt is disassembled, the sleeve and the nut in the sleeve can be disassembled together. The utility model solves the problem of the prior art that the sleeve is left in the coal mine, which wastes material. The utility model can be widely used for safety support for various tunnels.
Description
Technical field
The utility model belongs to coal mine roadway safety support technical field, relates to a kind of callable anchor pole and removal tool thereof concretely.
Background technology
At present, in order to prevent that the safety support anchor pole that tunnel landslide is installed from mostly being pipe seam formula, resin formula, cement formula, wherein resin anchor is because anchored force is big, dependable performance and generally being adopted in the colliery.But because the metallic rod body of resin anchor is not recyclable in the anchor hole in tunnel by resin solidification, metallic rod body easily causes the tool damage of excavator or both to clash into to produce spark and have the hidden danger that produces gas explosion in the exploitation process of tunnel.In order to address this problem, the patent No. provides a kind of adhered recoverable anchor rod for the patent of 01265700.x, mode by socket plastic sleeve on metallic rod body has reached the purpose that anchor pole reclaims again, this adhered recoverable anchor rod that this patent provided, can only reclaim Metallic rod, and plastic sleeve throwing away in vain caused the huge waste of material.
The utility model content
First purpose of the present utility model provides and a kind ofly can all reclaim, all utilizes again, safe and practical full recycling anchor pole.
Second purpose of the present utility model provides a kind of removal tool that can realize whole recovery to full recycling anchor pole.
The technical scheme of a kind of full recycling anchor pole that realization the utility model proposes is: include the metallic rod body that is through in the sleeve, described metallic rod body two ends are threaded and are socketed with hold-down nut and pallet in its bottom, its top is socketed with the platform shape nut with certain taper, described sleeve has internal thread, and its top has at least two cannelures that are divided into fin.
Its additional technical feature is: described shape nut side is fixed with the fixture block that at least one and sleeve cannelure are complementary; Be fixed with non-slipping block on the outer wall of described sleeve bottom: the reach of described sleeve lining is the 1/4-1/3 of length sleeve; The length of described cannelure is the 1/5-1/4 of length sleeve; Described sleeve employing has certain flexible metal material and makes; Have the sealing sliding tray on the described sleeve top inner wall, have the groove of being with kelly on described the shape nut sidewall; The big platform diameter of described shape nut equates with the outer diameter of sleeve.
What realization the utility model proposes can realize that all the technical scheme of the removal tool of recovery is to full recycling anchor pole: comprise having the screw rod that is complementary with internal thread of sleeve.
In addition, described screw tip center is fixed with the montant of diameter less than platform shape nut internal diameter.
A kind of full recycling anchor pole and removal tool thereof that the utility model provides, compare with prior art and to have the following advantages: one, owing to have at least two cannelures on the sleeve top, platform shape nut is the rounding platform with certain taper, when metallic rod body is tightened downwards, drive it and move down, the sleeve fin is strutted, play the firm effect of installing; They are two years old,: because sleeve lining is threaded and includes the screw rod that is complementary with the sleeve lining screw thread, when needs unload, metallic rod body is backed out in the other direction, screw in the screw rod that is complementary with the sleeve lining screw thread then, with platform shape nut jack-up, fin is under the effect of external force and self elastic force, restore to the original state, take out sleeve smoothly; The sleeve that takes out since not damaged almost therefore can utilize again; Its three owing to be fixed with anti-skidding projection in the sleeve bottom, when the precession screw rod, if when sleeve rotates synchronously with screw rod, available fastening devices is fixed this projection.Its four owing to have enclosed slot on the sleeve top inner wall, described the shape nut outside has the groove that has kelly, when taking out sleeve, takes platform shape nut out of by kelly.
Description of drawings
Fig. 1 is a kind of structural representation of full recycling anchor pole;
Fig. 2 is the cross-sectional view of kind of full recycling anchor pole;
Fig. 3 is the structural representation that has the platform shape nut of kelly.
Fig. 4 is for removing the tool construction figure of full recycling anchor pole.
The specific embodiment
Below in conjunction with drawings and Examples a kind of full recycling anchor pole that the utility model proposes and the structure and the use principle of removal tool thereof are described further.
As Fig. 1,2 are depicted as a kind of structural representation of full recycling anchor pole, this anchor pole comprises and being socketed with by having the sleeve 1 that elastomeric material (as steel plate) is made, pass the metallic rod body 2 of sleeve and TBE (threaded both ends), sleeve 1 top has and (generally is at least two, the best be three or) four cannelures 6 as shown in Figure 3, this cannelure is divided into four fins 8 with the sleeve top ends, the degree of depth of cannelure 6 is equivalent to the 1/4-1/3 (preferably 1/4) of length sleeve, and the inwall of sleeve 1 other end has the screw thread 9 that roughly is equivalent to its length 1/5, metallic rod body 2 bottoms of passing sleeve are socketed with hold-down nut 4 and pallet 3, the top be socketed with the outside for have a certain taper and little big platform shape nut 5 outward in big platform diameter is identical with sleeve outer diameter, these nut 5 outsides are fixed with can insert sleeve and this cannelure 6 corresponding fixture blocks 7, and the quantity of fixture block 7 also can be less than the quantity of cannelure 6.Outside wall surface is fixed with non-slipping block 11 in the bottom of sleeve 2, is beneficial to spanner when being used to dismantle and fixes.
Be illustrated in figure 4 as the tool construction figure that removes full recycling anchor pole, be an outer wall and have the screw rod 12 of the screw thread 14 of the sleeve 1 that can screw in full recycling anchor pole, its center, top is fixed with the montant 13 of a diameter less than platform shape nut screw 15.
During use, at first will be socketed with the anchor pole that sleeve, top be socketed with platform shape nut heads in the anchor hole, screw metallic rod body 2 by pallet 3 clockwise directions, the fixture block 7 that snaps in the platform shape nut cannelure 6 can make this nut maintain static, when screwing metallic rod body 2, drive platform shape nut 5 and move down, under the tension force effect of platform shape nut, the fin on sleeve top open gradually and with the hole wall stretching, be fixed in the hole firmly.When using the back dismounting, reverse rotation metallic rod body 2, and, then, sidewall is threaded 14 screw rod 12 screws in the sleeves 2 its extraction, the montant 13 on the top of screw rod 12 inserts in the screw of platform shape nut, and top on inciting somebody to action, firmly being pulled outwardly sleeve 2, the fin 8 at its top is under the pressure and the elastic force of self of hole wall, return to original state, and take out together.
In order to guarantee when extracting sleeve out, platform shape nut 5 to be taken out, on the wall at sleeve 2 tops, have sealing sliding tray 14, platform shape nut 5 outsides have the groove 16 of the kelly 10 that has as shown in Figure 3, are about to platform shape nut and are connected to the one that can slide relatively with sleeve.
