Description

Recoverable anchor rod supporting structure

Technical Field

The utility model relates to a technical field is strutted in the colliery, particularly, relates to a recoverable anchor bolt supporting construction.

Background

The anchor rod is the most basic component of roadway support in the contemporary coal mine and is used for reinforcing the coal wall and preventing the occurrence of rib caving. When the coal mining machine cuts coal during the production of the coal face, the support anchor rods of the coal wall at the mining side of the upper end and the lower end of the coal face can be brought into coal flow and even wound on the coal mining machine, certain damage is caused to the coal mining machine, even the damage to operators can be caused, and meanwhile, the influence of the support anchor rods entering the coal flow on the quality of the coal is large.

In this regard, there is a need for improvements in the prior art.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a recoverable anchor bolt supporting construction to the stock is brought into the coal-winning machine among the solution prior art and is caused certain damage, influences the problem of coal quality simultaneously in the coal-winning machine.

In order to achieve the above purpose, the utility model adopts the technical proposal that:

the utility model provides a recoverable anchor bolt supporting construction, includes mounting panel, stock and chain, mounting panel fixed mounting is on the tunnel roof, the stock include screw rod, suit on the screw rod anchor disc and with screw rod threaded connection's nut cap, be connected through the chain between mounting panel and the nut cap, and the chain is in the tight state that rises.

Preferably, the middle part of the anchor disc is provided with a through hole matched with the screw rod, and an arch-shaped bulge is arranged on the circumferential direction of the through hole on one side surface of the anchor disc.

Preferably, the mounting plate is provided with a plurality of hooks, and the hooks are detachably connected with the zipper.

Preferably, the nut cap is provided with a hook ring, and the hook ring is detachably connected with the zipper.

Compared with the prior art the utility model discloses beneficial effect who has:

the utility model relates to a recoverable anchor bolt supporting construction, coal-winning machine carry out the coal mining in-process to the coal face, and the stock can be retrieved automatically, can not get into the coal stream, has avoided coal-winning machine and operating personnel's harm effectively, simultaneously, has improved the coal quality.

Drawings

In order to more clearly illustrate the technical solution of the present invention, the drawings required for the embodiments will be briefly described below, and obviously, the drawings in the following description are only some embodiments of the present invention, and it is obvious for those skilled in the art that other drawings can be obtained according to the drawings without creative efforts.

Fig. 3 is a schematic structural view of the anchor disc of the present invention.

In the figure: 1. mounting a plate; 2. a chain; 3. hooking; 4. a screw; 5. an anchor plate; 6. a nut cap; 7. a threaded segment; 8. a through hole; 9. the arch is convex.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Furthermore, in the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "fixed" are to be construed broadly, e.g., as meaning fixedly connected, detachably connected, or integrally connected; may be a mechanical connection; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in fig. 1, a preferred embodiment of the present invention provides a recyclable anchor supporting structure, which includes: mounting plate 1, stock and chain 2.

Wherein, mounting panel 1 is rectangular shape steel sheet, and mounting panel 1 passes through bolt fixed mounting on the tunnel roof, and is specific, and the welding has a plurality of couples 3 on mounting panel 1.

Wherein, the stock includes screw rod 4, anchor dish 5 and nut cap 6.

As shown in fig. 2, a screw flight 7 is provided in the front half of the screw 4, the length of the screw flight 7 being less than half the length of the screw 4.

As shown in fig. 3, the anchor plate 5 is square and made of stainless steel, a through hole 8 matched with the screw rod 4 is formed in the middle of the anchor plate 5, an arched bulge 9 is formed in the circumferential direction of the through hole 8 in one side surface of the anchor plate 5, and the anchor plate 5 is sleeved on the screw rod 4.

The nut cap 6 is in threaded connection with the screw rod 4, and a hook ring is arranged on the nut cap 6.

Wherein, one end of the chain 2 is detachably hung on the hook 3 of the mounting plate 1, and the other end of the chain 2 is detachably hung on the hook ring of the nut cap 6.

Further, the chain 2 is in a tensioned state.

The use principle of the utility model is explained as follows:

firstly, the mounting plate 1 is fixedly mounted on a roadway top plate.

Then, a drilling machine is used for drilling an anchor hole, anchoring agent is added into the anchor hole, the screw rod 4 extends into the anchor hole to be stirred, the anchoring agent reacts and anchors the screw rod 4, the anchor disk 5 is sleeved on the screw rod 4 leaking out of the coal wall, one side surface of the arched bulge 9 of the anchor disk 5 faces outwards, the anchor disk 5 is used for preventing the anchoring agent in the anchor hole from overflowing, and the nut cap 6 is screwed on the screw rod 4 and fastened.

And finally, hanging one end of the chain 2 on the hook 3 of the mounting plate 1, hanging the other end of the chain 2 on a hook ring of the nut cap 6, and adjusting the length of the chain 2 according to the field condition to enable the chain 2 to be in a tensioning state.

And completing the anchor bolt support.

The coal mining machine cuts and mines the coal face, when the coal is mined to the periphery close to the anchor rod, the coal body is soft, the anchor rod is pulled out of the coal bed under the action of the pulling force of the chain 2, and the anchor rod is prevented from entering the coal flow.

To sum up, the embodiment of the utility model provides a recoverable supporting structure of stock, the coal-winning machine carries out the coal mining in-process to the coal face, the stock can be retrieved automatically, can not get into the coal stream, has avoided coal-winning machine and operating personnel's harm effectively, simultaneously, has improved the coal quality.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
