Description

Technical Field

[0001] The utility model relates to the technical field of mining machinery, and specifically relates to an anchor protection tooling for the end frame of an extended tail beam in gob-side entry retaining. Background Technique

[0002] At present, the gob-side entry retaining technology is adopted in the mining face. During production, as the fully-mechanized mining face advances and the conveyor moves up and down, when the roof changes from hard to soft or vice versa, due to the relatively long tail beam of the No. 2 end support near the adjacent roadway (gateway), irreversible damage is caused to the roof anchor cables and steel belts during the lifting and lowering process, resulting in the failure of roof support and posing a great potential safety hazard to the roof.

[0003] At present, in order to avoid damaging the roof anchor cables, respond to the concept of mining safety, ensure the integrity of the original roof support, reduce the labor and material costs brought by subsequent supplementary drilling of anchor cables, and eliminate potential safety hazards. Content of the Utility Model

[0004] The purpose of the utility model is to provide an anchor protection tooling for the end frame of an extended tail beam in gob-side entry retaining, which can effectively solve the problems existing in the background technique.

[0005] To solve the problems existing in the background technique, it includes first ear seats 2 installed on both sides of the end of the telescopic tail beam 1 and a support box body 4 arranged on the telescopic tail beam 1. A connecting plate 3 rotatably connected and matched with the first ear seats 2 is installed on the first ear seats 2. The end of the connecting plate 3 is installed with a second ear seat 5 rotatably connected and matched with the connecting plate 3. The second ear seat 5 is fixedly installed on the outer side surface of the support box body 4.

[0006] The first ear seat 2 and the connecting plate 3 are rotatably connected and matched through a first pin shaft 6.

[0007] The second ear seat 5 and the connecting plate 3 are rotatably connected and matched through a second pin shaft 7.

[0008] The support box body 4 is an overall cuboid box-shaped structure with an opening on the upper top surface.

[0009] Due to the adoption of the above technical solutions, the utility model has the following beneficial effects:

[0010] During the mining process of the working face, the destructive effect of the original head extended tail beam support on the roof anchor is transformed into a protective effect, turning disadvantages into advantages.

[0011] The coordinated cooperation of the anchor protection tooling and the telescopic tail beam can realize the manual adjustment of the anchor protection distance, achieve accurate anchor protection, and can be installed once and used for a long time.

[0012] According to the current advancing speed of the working face, it advances about 6 - 7 m in a round shift. For every 1 m, one cable bolt needs to be supplemented. By using this tooling, 6 - 7 cable bolts can be supplemented less per shift, saving material costs;

[0013] It mainly protects the original cable bolt support, eliminates the hidden danger of roof safety, and effectively avoids the roof safety risk caused by the failure of roof support. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] In order to more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the following will briefly introduce the drawings required for the description of the embodiments or the prior art. Obviously, the following drawings are only some embodiments of the present invention. For those of ordinary skill in the art, without creative efforts, other drawings can be obtained based on these drawings.

[0015] Figure 1 is a schematic structural diagram of the present invention;

[0016] Figure 2 is a top view of the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0018] Refer to Figure 1-2 , this specific embodiment is implemented by the following technical solutions. It includes first ear seats 2 installed on both sides of the end of the telescopic tail beam 1 and a support box body 4 arranged on the telescopic tail beam 1. A connecting plate 3 rotatably connected therewith is installed on the first ear seat 2. The end of the connecting plate 3 is installed with a second ear seat 5 rotatably connected therewith. The second ear seat 5 is fixedly installed on the outer side surface of the support box body 4.

[0019] The first ear seat 2 and the connecting plate 3 are rotatably connected and cooperated through a first pin shaft 6.

[0020] The second ear seat 5 and the connecting plate 3 are rotatably connected and cooperated through a second pin shaft 7

[0021] The support box body 4 is an overall cuboid box-shaped structure with an opening on the upper top surface.

[0022] The following further elaborates on the usage method and its principle of the technical solution part in this specific embodiment with reference to the drawings:

[0023] During operation, the distance of the telescopic tail beam 1 can be adjusted by lifting the frame, and by observing the positions of the support box body 4, the cable anchor to be protected and the tray, the frame can be finally lifted to make the box body avoid the cable anchor and the tray, so as to play a role in protecting the cable anchor.

[0024] This specific implementation is simple to operate and can effectively solve the drawback that the lengthened tail beam of the No. 2 end support directly damages the cable anchor with the advancement of the working face, and the on-site use effect is good.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
