Abstract
A kind of for improving the device of anchorage cable anchoring under coal mine, comprise the hollow cylinder that can be enclosed within on anchor cable, on hollow cylinder, be evenly distributed with three fixed-wings that can enter in anchor cable boring, this hollow cylinder is provided with a screw hole and the cylindrical screw of fixation hollow.This device can make anchorage cable anchoring section be placed in all the time the middle of boring, can realize all thick being distributed between anchor cable and drill hole wall of Anchor Agent, thereby the Anchor Agent that makes each orientation of anchorage cable anchoring section has identical and higher anchoring ability, significantly improve the anchoring of anchorage cable anchoring section, improve the control effect of anchor cable to surrouding rock deformation, better safeguard stability of the roadway, and this apparatus structure is simple, convenient to use, there is compliance and practicality widely.
Description
Technical field
The utility model relates to a kind of for improving the device of anchorage cable anchoring under coal mine, is particularly useful for making under coal mine all thick solidity that improves anchor cable anchor between anchor cable and drill hole wall with this that is distributed in of Anchor Agent.
Background technology
The resin anchoring agent that macromolecular material is made, adhesive strength is large, and quick solidifying is safe and reliable, has been widely used in the supporting of coal mine roadway anchor cable.The bore diameter of using due to existing colliery and the difference of anchor cable diameter are generally all between 8 ~ 14mm, anchor cable is in the process of agitating resin Anchor Agent, can cause a side of anchor cable deflection drill hole wall, thereby cause the Anchor Agent between anchor cable and boring to distribute very inhomogeneous, occur that Anchor Agent distributes in a side thicker, the situation that opposite side distribution is thinner, thicker and comparatively serious compared with the Bao Douhui anchoring property that affects Anchor Agent that Anchor Agent distributes, significantly reduce the anchored force of resin anchoring agent, easily there is anchored end sliding phenomenon, significantly reduce the effect of safeguarding stability of the roadway with anchor cable.When particularly anchor cable is safeguarded stability of the roadway, generally all adopt end anchor mode, because anchor cable drilling depth is large, while being easy to occur sending into resin anchoring agent with anchor cable, because cable body is pressed close to a certain side of drill hole wall, there is large space in opposite side, Anchor Agent is easy to enter the larger side in space so, and cannot make Anchor Agent send into foot of hole, and cause anchorage length not reach designing requirement, seriously reduce the anchoring effect of anchor cable.
Summary of the invention
The purpose of this utility model is for having problems in prior art, a kind of easy for installation, economical rationality is provided, can effectively solve Anchor Agent distributed pole between boring and anchor cable inhomogeneous for improving the device of anchorage cable anchoring under coal mine.
For achieving the above object, of the present utility model for improving the device of anchorage cable anchoring under coal mine, comprise the hollow cylinder that can be enclosed within on anchor cable, on hollow cylinder, be evenly equipped with three fixed-wings that can enter in anchor cable boring, fixation hollow cylinder is provided with a screw hole and enters the hold-down screw leaning at anchor cable through screw hole.
The outward flange of described three fixed-wings is circular-arc; The height of described hollow cylinder is decided to be 2cm.
Beneficial effect: the utility model is by three wings that are distributed on hollow cylinder, and hold-down screw composition, can make anchorage cable anchoring section be placed in all the time the device of boring middle, there is the hollow cylinder that can be enclosed within on anchor cable, can realize all thick being distributed between anchor cable and drill hole wall of Anchor Agent, thereby the Anchor Agent that makes each orientation of anchorage cable anchoring section has identical and higher anchoring ability, the Anchor Agent that can make anchorage cable anchoring section is thick being distributed between anchor cable and drill hole wall all, structure and manufacture are all comparatively simple, easy to use, install fast, well solve because of Anchor Agent skewness between boring and anchor cable, have a strong impact on the problem of anchoring effect, by installing after this device, in the time anchor cable being sent into boring, the anchor cable moment is in the middle of boring, thereby make Anchor Agent be sent to smoothly foot of hole, what three fixed-wings on this device can stir Anchor Agent simultaneously is more even, effectively improve the anchored force of Anchor Agent, significantly improve the anchoring effect of anchor cable.This device can improve the anchoring of anchorage cable anchoring section comparatively significantly, improves the control effect of anchor cable to surrouding rock deformation, better safeguard stability of the roadway, and this apparatus structure is simple, convenient to use, has compliance and practicality widely.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model in wall rock drill-hole.
Fig. 2 is the schematic diagram of the screw hole position on hollow cylinder.
In figure: 1-roadway surrounding rock body, the boring of 2-anchor cable, 3-hollow cylinder, 4-is inserted in circular hole, 5-screw hole, the 6-hold-down screw of anchor cable, 7-fixed-wing.
Detailed description of the invention
Below in conjunction with accompanying drawing, an embodiment of the present utility model is further described:
As shown in Figure 1, the utility model is for improving the device of anchorage cable anchoring under coal mine, comprise the hollow cylinder 3 that can be enclosed within on anchor cable, be evenly equipped with three fixed-wings that can enter in anchor cable boring 2 on hollow cylinder 3, the outward flange of three fixed-wings is circular-arc.Fixation hollow cylinder 3 is provided with a screw hole and enters the hold-down screw 6 leaning at anchor cable through screw hole.The interior circular diameter of hollow cylinder 3 is a bit larger tham anchor cable diameter, and the outer diameter of a circle of hollow cylinder is slightly larger than interior diameter of a circle, and the height of hollow cylinder 3 is decided to be 2cm.
Under coal mine, use, anchor cable boring 2(Φ 28 × 6500 first constructs on roadway surrounding rock body 1), anchor cable diameter 17.8mm, takes to hold anchor mode, anchorage length 1.5m; 3 this device spacing distances are installed to anchor cable to be treated on anchoring section, tighten hold-down screw 6, this device and anchor cable are tightly fixed together, resin anchoring agent and the anchor cable that has installed this device send in anchor cable boring 2, agitating resin Anchor Agent, until resin anchoring agent solidifies after certain hour, anchor rope supporting plate is installed and is applied pretightning force to anchor cable.The interior circular diameter of hollow cylinder 3 is a bit larger tham anchor cable diameter, and outer diameter of a circle is than the large 3 ~ 4mm of interior diameter of a circle, and the height of hollow cylinder is decided to be 2cm, can realize and directly be inserted in anchor cable, and can be screwed, and to realize, this device is conveniently installed.Three wings on described hollow cylinder, are fixed on hollow cylinder, and the angle between the center line of three wings is adjacent is 120
0, the outer rim of the wing adopts circular arc design, and the radius of circular arc is less than the radius of boring, and the two ends of the outer rim of the wing also adopt circular arc design, can significantly reduce like this frictional force between three wings and drill hole wall, improve the efficiency that anchor cable is installed; The central angle separately of three wings is all decided to be 30 simultaneously
0~ 40
0, the thickness of the wing is 2cm, and the space between such three wings can allow the Anchor Agent having stirred pass through smoothly, and it is more even that while three wings can also stir Anchor Agent.
