Its additional technical feature is:
Be provided with end cover at described sleeve top, be provided with non-slip process on described end cover top;
Between described expansion set rearward end and described apical ring, be provided with pad;
Described sleeve and described cone are fixed together;
Be provided with groove in described cartridges sides;
Be provided with vertically anti-skidding muscle in described cartridges sides;
Be inlaid with the tension pad in described nut slideway rear end.
The recyclable expansion sleeve type anchor pole of quick mounting provided by the utility model compared with prior art has the following advantages: one, owing to comprise cone, be placed in the expansion set and the body of rod that have expansion joint (E.J.) on this cone, on described cone, have body of rod through hole, front end in described cone is provided with sleeve, in described sleeve, be provided with the nut slideway of inwall and nut outer rim coupling, in described nut slideway, be provided with the nut that can in this nut slideway, move, described body of rod top is spun on described nut, be positioned at the described body of rod of expansion set rearward end and be provided with apical ring, when with cone, after the expansion set and the body of rod assemble and head into anchor hole, the nut that is rotary with the body of rod is under action of inertia, be positioned at nut slideway front end, when the rotation body of rod, can be easy to cone is advanced in the expansion set, therefore can directly rotate the body of rod with the nut screwing mechanism, when the body of rod rotates, the top of the body of rod can have the reach of body of rod through hole on cone, enter in the sleeve, prevented that the body of rod from withstanding on the anchor hole top, influence body of rod rotation, thereby driving cone moves to expansion set one end, and expansion set is under the effect of apical ring, prevented to move behind the expansion set, help mechanized operation, improved working efficiency; They are two years old, owing to be provided with end cover at described sleeve top, be provided with non-slip process on described end cover top, metallic rod body is not exposed under the moist environment, prevented that the body of rod from being corroded, make when reclaiming, to be more conducive to back out and when rotating the body of rod, to have prevented to relatively rotate between cone and the anchor hole, help cone the expansion set distending; Its three owing between described expansion set rearward end and described apical ring, be provided with pad, when the rotation body of rod, prevented that apical ring from pushing up bad expansion set; Its four owing to be provided with groove or be provided with vertically anti-skidding muscle, prevented to relatively rotate between cone and the anchor hole in described cartridges sides in described cartridges sides; They are five years old, owing to be inlaid with the tension pad in described nut slideway rear end, prevented when the body of rod rotates the cone drawing crack, having improved tensile strength, is the body of rod of 16mm for diameter, and the tensile strength of existing anchor pole is 40,000 Ns, the anchor pole ground tensile strength that has the tension pad reaches 80,000 Ns, and be the body of rod of 18mm for diameter, the tensile strength of existing anchor pole is 60,000 Ns, has the anchor pole ground tensile strength of tension pad to reach more than 100,000 Ns.
Description of drawings
Fig. 1 is the structural representation of the recyclable expansion sleeve type anchor pole of the utility model quick mounting;
Fig. 2 is the A-A sectional view of Fig. 1.
Embodiment
Be described in further details below in conjunction with the structure and the use principle of accompanying drawing the recyclable expansion sleeve type anchor pole of the utility model quick mounting.
As depicted in figs. 1 and 2, the recyclable expansion sleeve type anchor pole of the utility model quick mounting comprises cone 1, be placed in the body of rod 3 that expansion set 2 on the cone 1 and metallic material are made, on expansion set 2, have expansion joint (E.J.) 21, on cone 1, have body of rod through hole 12, front end in cone 1 is provided with sleeve 4, in sleeve 4, be provided with nut slideway 41, in nut slideway 41, be provided with the nut 42 that can in this nut slideway 41, move, nut slideway 41 inwalls and nut 42 outer rims coupling, nut 42 can not rotate in nut slideway 41.Nut 42 is spun on the body of rod 3, and the body of rod 1 that is positioned at the rearward end of expansion set 2 is provided with apical ring 31.In order to prevent apical ring 31 top bad expansion sets 2, between the rearward end of expansion set 2 and apical ring 31, be provided with pad 32.
Because anchor pole generally uses more than half a year in mine, and there was dampness in the air in the tunnel, metallic rod body 3 is easy to corrosion, in order to prevent that the body of rod 3 from being corroded, is provided with end cover 47 at the top of sleeve 4.
Relatively rotate between cone 1 and the anchor hole in order to prevent to rotate the body of rod 1, help cone 1 with expansion set 2 distendings, sleeve 4 is fixed together with cone 1, and can be provided with non-slip process 43 at end cover 47 front ends, can also be provided with groove 44 in the side of sleeve 4, can be provided with anti-skidding muscle 45 vertically again in the side of sleeve 4, said method can also use simultaneously.
In order to improve tensile strength, when rotating, the body of rod, is inlaid with tension pad 46 in the rear end of nut slideway 41 with the cone drawing crack.Like this, for diameter is the body of rod of 16mm, the tensile strength of existing anchor pole is 40,000 Ns, the anchor pole ground tensile strength that has the tension pad reaches 80,000 Ns, and be the body of rod of 18mm for diameter, the tensile strength of existing anchor pole is 60,000 Ns, has the anchor pole ground tensile strength of tension pad to reach more than 100,000 Ns.Improved tensile strength greatly.
During use, cone 1, expansion set 2, the body of rod 3 and sleeve 4 assembled head into anchor hole, directly rotate the body of rod 3 with the nut screwing mechanism, nut 42 is fixed in the sleeve 4, and when the body of rod 3 rotated, nut 42 can move behind nut slideway 41, and expansion set 2 is under the pushing tow of apical ring 31, prevented to move behind the expansion set 2, like this, cone 1 can be rapidly with expansion set 2 distendings, withstand on the anchor hole wall, do not need inwardly firmly to impact expansion set 2, help mechanized operation, improved working efficiency.
