Description

Technical Field

[0001] This utility model relates to the field of mine support technology, specifically a quick-installation mine support anchor tray. Background Technology

[0002] Mine support is a crucial technical aspect of the mining process, aiming to maintain the stability of the surrounding rock through engineering means, ensuring operational safety and production efficiency. After mine excavation, the top of the tunnel loses the support of the underlying mineral mass. Larger mineral masses will remain relatively stable due to the clamping force of the surrounding mineral masses. However, smaller minerals, due to insufficient clamping force to overcome their gravity, will partially fall, affecting the safe production of the mine. Anchor bolts or cables are often used to connect the surrounding rock to the deeper stable rock mass, utilizing friction or adhesion to transfer stress and enhance the self-supporting capacity of the surrounding rock.

[0003] Referring to Chinese Patent Publication No. CN222162670U, with the publication date of December 13, 2024, an anchor rod with built-in resin anchoring agent is disclosed. This utility model pushes the rod into a pre-drilled hole, and pushes the anchoring agent out of the rod body by pushing, thus completing the resin anchoring and mixing. From drilling the hole to completing the installation, only two steps are required to install the anchor rod. In addition, the outer packaging of the anchoring agent can be filtered, and the outer packaging will not continue to be squeezed out, thereby ensuring the smooth extrusion of the anchoring agent.

[0004] However, during the use of this utility model, it is inconvenient to fix the anchor rod in the borehole when releasing the anchoring agent, and it is also inconvenient to release the anchoring agent evenly in the borehole. In addition, when connecting the anchor rod, tray and tunnel, if the tunnel and the borehole are inclined, it is inconvenient to fit the anchor rod tray tightly with the tunnel, which makes quick installation inconvenient. Therefore, there is still room for further improvement.

[0005] Therefore, we propose a quick-installation anchor bolt tray for mine support to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide a quick-installation anchor bolt tray for mine support, in order to solve the problems mentioned in the background art. Specifically, during use, it is inconvenient to fix the anchor bolt in the borehole when releasing the anchoring agent, and it is also inconvenient to evenly release the anchoring agent into the borehole. Furthermore, when connecting the anchor bolt, tray, and roadway, if the roadway and borehole are inclined, it is inconvenient to tightly fit the anchor bolt tray with the roadway, thus hindering quick installation. Therefore, there is still room for further improvement.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a quick-installation anchor bolt tray for mine support, comprising:

[0008] An anchor bolt body, wherein a retaining ring is provided inside the anchor bolt body, and the anchor bolt body is threadedly connected to a fastening nut;

[0009] Also includes:

[0010] The upper side of the anchor bolt body is provided with a quick-release mechanism for releasing the anchoring agent, and the upper side of the anchor bolt body is threadedly connected to the threaded sleeve.

[0020] Preferably, the lower side of the anti-slip plate is provided with anti-slip blocks, and the anti-slip blocks are distributed in an array.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows: The quick-installation anchor bolt tray for mine support has a locking block inside the uniform conveying pipe. When the anchoring agent is discharged from the slot, the locking block will be in an inclined state. The inclined locking block will also play a reinforcing role, thus facilitating quick installation. Rotating the threaded rod will allow the connecting ring to move upward, and the connecting ring will be rotatably connected to the connecting plate. Therefore, the connecting ring will cause the connecting plate to rotate with the tray body, thereby realizing the angle adjustment and further facilitating quick installation.

[0022] 1. It is equipped with an anchor bolt body, a retaining ring and a piston. The retaining ring is located inside the lower part of the anchor bolt body. The retaining ring can prevent the piston and resin anchoring agent from sliding out from the lower part of the anchor bolt body.

[0023] 2. It is equipped with resin anchoring agent, anchoring agent coating separator and mixer. The anchoring agent coating separator is located above the resin anchoring agent. When the resin anchoring agent comes into contact with the anchoring agent coating separator, the sharp teeth on the inside of the anchoring agent coating separator will puncture the resin anchoring agent, and then the anchoring agent will be discharged from the resin anchoring agent. After being mixed by the mixer, it is released into the homogenization delivery pipe and finally discharged into the borehole.

[0024] 3. It is equipped with a homogenizing conveying pipe, a slot, and a clamping block. The clamping block is rotatably connected inside the homogenizing conveying pipe. When the anchoring agent is discharged from the slot, the clamping block will be in an inclined state. The inclined clamping block will also play a reinforcing role, thus facilitating quick installation.

[0025] 4. It is equipped with a tray body, an anti-slip plate, and a sliding groove. The anchor bolt body passes through the tray body and the anti-slip plate, and the fastening nut is threadedly connected to the anchor bolt body to lock it in place.

[0026] 5. It is equipped with a sliding block, a threaded rod, and a connecting ring. The sliding block is slidably connected to the sliding groove, and the sliding block is rotatably connected to the threaded rod. The threaded rod is threadedly connected to the connecting ring. Therefore, rotating the threaded rod will allow the connecting ring to move upward. The connecting ring is rotatably connected to the connecting plate, so the connecting ring will cause the connecting plate to rotate along with the tray body, thereby achieving angle adjustment and further facilitating quick assembly.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Please see Figures 1-6 As shown, this utility model provides a technical solution: a quick-installation anchor bolt tray for mine support, comprising: an anchor bolt body 1, a retaining ring 2, a piston 3, a resin anchoring agent 4, an anchoring agent coating separator 5, a mixer 6, a homogenizing conveying pipe 7, a threaded sleeve 8, a slot 9, a locking block 10, a fastening nut 11, a tray body 12, an anti-slip plate 13, a sliding groove 14, a sliding block 15, a threaded rod 16, a connecting ring 17, a connecting plate 18, and an anti-slip block 19.

[0036] The existing utility model is inconvenient to fix the anchor rod in the borehole when releasing the anchoring agent, and it is also inconvenient to release the anchoring agent evenly in the borehole. In addition, when connecting the anchor rod, tray and tunnel, if the tunnel and the borehole are inclined, it is inconvenient to fit the anchor rod tray tightly with the tunnel, which makes quick installation inconvenient. Therefore, there is still room for further improvement.

[0037] like Figure 3As shown, a retaining ring 2 is provided at the lower interior of the anchor bolt body 1, and a piston 3 slides inside the anchor bolt body 1. The retaining ring 2 prevents the piston 3 and the resin anchoring agent 4 from sliding out from the lower interior of the anchor bolt body 1. In addition, the anchoring agent outer coating separator 5 is located above the resin anchoring agent 4. When installing the anchor bolt, the anchor bolt body 1 and the homogenization delivery pipe 7 are first inserted into the borehole. Then, when it is necessary to release the anchoring agent from the anchor bolt body 1 into the borehole, the piston 3 moves upward inside the anchor bolt body 1. At this time, the resin... The anchoring agent 4 is carried upward by the piston 3. When the resin anchoring agent 4 comes into contact with the anchoring agent outer coating separator 5, the sharp teeth on the inner side of the anchoring agent outer coating separator 5 will puncture the resin anchoring agent 4, and then the anchoring agent will be discharged from the resin anchoring agent 4. As the resin anchoring agent 4 moves upward, its outer side is tightly attached to the inner wall of the anchor rod body 1, so the anchoring agent will be discharged from the resin anchoring agent 4 and enter the anchoring agent outer coating separator 5. After being mixed by the mixer 6, it is released into the homogenization delivery pipe 7.

[0038] like Figure 3 and Figure 4 As shown, the homogenizing delivery pipe 7 is connected to the anchor bolt body 1 through a threaded sleeve 8. The homogenizing delivery pipe 7 has a slot 9 inside, and a locking block 10 is rotatably connected inside the homogenizing delivery pipe 7. When the anchoring agent enters the homogenizing delivery pipe 7, the anchoring agent will be discharged from the slot 9. At this time, the locking block 10 will rotate and be in an inclined state. Finally, the anchoring agent is discharged into the borehole. After the anchoring agent solidifies, the locking block 10 will be in an inclined state. The inclined locking block 10 can also increase the contact area between the homogenizing delivery pipe 7 and the anchoring agent or the borehole, thereby playing a reinforcing role and facilitating quick installation. In addition, the slots 9 are distributed in an array, so the anchoring agent will be evenly delivered into the borehole.

[0039] like Figure 1 , Figure 5 and Figure 6 As shown, the anchor bolt body 1 passes through the tray body 12 and the anti-slip plate 13, and the fastening nut 11 is threadedly connected to the anchor bolt body 1. After the anchor bolt body 1 is connected to the drilled hole by the anchoring agent, the fastening nut 11 is threadedly connected to the anchor bolt body 1. At this time, the tray body 12 and the anti-slip plate 13 will be fixedly connected to the anchor bolt body 1, which plays a locking role.

[0040] like Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, if the borehole in the tunnel is not perpendicular to the outer facade of the tunnel, the pallet body 12 and the anchor bolt body 1 cannot be tightly connected, thus making quick installation impossible. Since the anti-slip plate 13 has a sliding groove 14 inside, and the sliding block 15 is slidably connected to the sliding groove 14, and the sliding block 15 is rotatably connected to the threaded rod 16, and the threaded rod 16 is threadedly connected to the connecting ring 17, and the connecting ring 17 is rotatably connected to the connecting plate 18, rotating the threaded rod 16 will allow the connecting ring 17 to move upward. Therefore, the connecting ring 17 will cause the connecting plate 18 to rotate along with the pallet body 12, thereby achieving angle adjustment. At this time, the anti-slip plate 13 will fit tightly with the tunnel, further facilitating quick installation, which is very convenient. The sliding block 15 will move within the sliding groove 14. In addition, an anti-slip block 19 is provided on the upper side of the anti-slip plate 13 to further prevent slippage.
