Description
Technical field
The utility model belongs to the anchor pole technical field, relates in particular to a kind of quick mounting expansion sleeve type anchor pole.
Background technique
Recoverable anchor rod is for preventing the widely used safety support anchor pole of tunnel landslide in the colliery.The structure of this anchor pole, the nut that includes pallet, metallic rod body, is used to connect this metallic rod body and is embedded in the expansion set inner top.When mounted, need firmly inwardly to impact expansion set, use mechanical inside precession metallic rod body again after waiting expansion set and anchor hole wall jam-packed, like this, the speed of installation reduces greatly.
The model utility content
The technical problem of solution of the present utility model just provides a kind of easy to use, quick mounting expansion sleeve type anchor pole of being convenient to install.
For solving the problems of the technologies described above, the technological scheme that the utility model quick mounting expansion sleeve type anchor pole adopts is: comprise internal fixation have nut 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, is positioned at the described body of rod of expansion set rearward end and is provided with apical ring.
Its additional technical feature is:
Be provided with anti-slip tank at described sleeve top;
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;
Described nut is a platform shape nut.
Quick mounting expansion sleeve type anchor pole provided by the utility model compared with prior art has the following advantages: one, owing to comprise that internal fixation has the cone of nut, 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, 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, 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, has prevented that the body of rod from withstanding on the anchor hole top, influence body of rod rotation, move to expansion set one end thereby drive cone, and expansion set has prevented to move behind the expansion set under the effect of apical ring, help mechanized operation, improved working efficiency; Its two owing to be provided with end cover at described sleeve top, metallic rod body is not exposed under the moist environment, has prevented that the body of rod from being corroded, and makes to be more conducive to back out when reclaiming; They are three years old, owing to be provided with anti-slip tank at described sleeve top, be provided with non-slip process on described end cover top and be provided with groove or anti-skidding muscle vertically in described cartridges sides, when rotating the body of rod, prevented to relatively rotate between cone and the anchor hole, helped cone the expansion set distending; Its four 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; They are five years old, because described nut is a platform shape nut, 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.

Embodiment
Be described in further details below in conjunction with the structure and the use principle of accompanying drawing the utility model quick mounting expansion sleeve type anchor pole.
As shown in Figure 1, the utility model quick mounting expansion sleeve type anchor pole comprises cone 1, be placed in the body of rod 3 that expansion set 2 on the cone 1 and metallic material are made, in cone 1 internal fixation nut 11 is arranged, on expansion set 2, have expansion joint (E.J.) 21, have body of rod through hole 12 on cone 1, the body of rod 3 passes nut 11 and body of rod through hole 12 can stretch out cone 1.Front end in cone 1 is provided with sleeve 4, and the body of rod 3 that is positioned at expansion set 2 rearward end is provided with apical ring 31, and apical ring 31 withstands on the rearward end of expansion set 2.
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, as shown in Figure 2, is provided with end cover 41 at the top of sleeve 4.
To relatively rotate between cone 1 and the anchor hole in order preventing to rotate the body of rod, to help cone 1 with expansion set 2 distendings, sleeve 4 is fixed together with cone 1, can be provided with anti-slip tank 42 at sleeve 4 tops as shown in Figure 1; Also can be provided with non-slip process 43 at end cover 41 front ends as shown in Figure 2; Can also be provided with groove 44 in the side of sleeve 4 as shown in Figure 3 and Figure 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 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.
In order to prevent that when the body of rod 3 rotation cone 1 drawing crack is improved tensile strength, nut 11 is a platform shape nut.
During use, cone 1, expansion set 2 and the body of rod 3 assembled head into anchor hole, directly rotate the body of rod 3 with the nut screwing mechanism, nut 11 is fixed in the cone 1, and when the body of rod 3 rotated, the top of the body of rod 3 can be along 12 reaches of the body of rod through hole on the cone 1, 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.
