Abstract
The utility model is related to a kind of cable bolting joists, belong to colliery tunnel support technical field, including anchor cable, support plate and lockset, the anchor cable is fixed in the support plate by the lockset, the support plate includes U-shaped steel frame and the supporting plate of the upper groove surface opening welding in the U-shaped steel frame, the hole of the support plate is penetrated through there are two being set on the bottom surface of the U-shaped steel frame, the anchor cable passes through the hole, one end of the anchor cable is fixed on the U-shaped steel frame by the lockset, the utility model is by being arranged supporting plate, anchor cable fastener can effectively be avoided and form point contact at the top of tunnel, the integral reinforcing ability of cable bolting can be increased, improve the stability and globality of roadway surrounding rock control.
Description
Technical field
The utility model is related to colliery tunnel support technical field more particularly to a kind of anchor cable branch of underground coal mine supporting
Protect joist.
Background technology
Deep-well compound roof soft-rock tunnel, fully-mechanized digging machine cutting（Bursting work）After coal breakage, empty top zone domain need to be carried out permanent
Supporting.In order to ensure the globality and stability of back, anchor cable is needed to fix, is applied to roof timbering object by anchor cable pulling force
Add towing force, inhibits directly top chance water generation swelling stress that the supportings object such as anchor pole, anchor cable is caused to fail.Current roof timbering owner
Anchor cable pallet is used, is process by square iron plate, central bore, anchor cable pallet is by the downward pressure in coal seam and drawing
Power, therefore the position that anchor cable pallet is connect with anchor cable is easy to happen recess, aperture by as the relative weakness of entire anchor cable pallet
Become larger or produces fracture phenomenon.In addition, anchor cable pallet is directly contacted with back, anchor cable lock and anchor cable pallet are easily and top plate
Point contact is formed, causes anchor cable that failure by shear occurs.
Invention content
To overcome above-mentioned technical problem, the utility model to provide a kind of anchor that can improve top plate globality and stability
Rope supporting joist.
To achieve the above object, the utility model is realized using following technical scheme：
The anchor cable is fixed on the branch by a kind of cable bolting joist, including anchor cable, support plate and lockset, the lockset
On fagging, the support plate includes U-shaped steel frame and the supporting plate of the upper groove surface opening welding in the U-shaped steel frame, described U-shaped
It is set on the bottom surface of steelframe there are two the hole for penetrating through the support plate, the anchor cable passes through the hole, and the lockset is by the anchor cable
One end be fixed on the U-shaped steel frame.
Width of the width of the supporting plate not less than the upper groove surface opening of the U-shaped steel frame.
The supporting plate is made of three parts, and middle section and the both ends part of the supporting plate, which are respectively equipped with, can make the anchor cable
The gap passed through.
Pallet is equipped between the U-shaped steel frame and the lockset.
It is welded with side guard plate in the both ends of the surface of the U-shaped steel frame, the upper surface of the side guard plate is not higher than the supporting plate
Upper surface.
The utility model has the positive effect that：
Back area of suspension roof can be effectively reduced by the way that supporting plate is arranged, is applied to roof timbering object by anchor cable pulling force
Towing force avoids anchor cable firmware and forms point contact at the top of tunnel, fails so as to cause the supportings object such as anchor pole, anchor cable.

Specific implementation mode
Referring to Fig. 1,2,3, a kind of cable bolting joist, including anchor cable, support plate and lockset, the lockset is by the anchor cable
It is fixed in the support plate, the support plate includes the support of U-shaped steel frame and the upper groove surface opening welding in the U-shaped steel frame
Plate is set on the bottom surface of the U-shaped steel frame there are two the hole for penetrating through the support plate, and the anchor cable passes through the hole, the lock
One end of the anchor cable is fixed on the U-shaped steel frame by tool, and the width of the supporting plate is not less than the upper groove surface of the U-shaped steel frame
The width of opening, when the width of the supporting plate be more than the U-shaped steel frame upper groove surface opening width when, the supporting plate with
Contact surface bigger at the top of tunnel, can be safer bear higher anchor cable pulling force；The supporting plate is made of three parts, described
The middle section of supporting plate is respectively equipped with the gap that the anchor cable can be made to pass through with both ends part, and the supporting plate subsection setup can be kept away
Exempt to punch so that anchor cable passes through on the supporting plate；Pallet is equipped between the U-shaped steel frame and the lockset, it is possible to increase described
Contact area between lockset and the U-shaped steel frame avoids the lockset from forming point contact with the U-shaped steel frame, causes anchor cable tight
Gu failure；It is welded with side guard plate in the both ends of the surface of the U-shaped steel frame, the upper surface of the side guard plate is upper not higher than the supporting plate
End face is arranged the side guard plate in the both ends of the surface of the U-shaped steel frame, can reinforce the enabling capabilities of the U-shaped steel frame, avoid by
It is excessive in anchor cable pulling force, cause the supporting plate weld failure, the U-shaped steel frame to crack along upper groove surface opening.
The operation principle of the utility model is as follows：
Before the utility model use, poured by punching loading anchor cable 1 in the country rock of tunnel top, later by anchor cable 1
Across hole 6, pallet 7 is penetrated after anchor cable 1, anchor cable 1 is fastened on U-shaped steel frame 4 by lockset 3.
