Description

Technical Field

[0001] This utility model relates to the field of anchor ring inlay technology, specifically to an anchor ring inlay mold for anchor rods used in metal mines. Background Technology

[0002] Metal mine anchor bolts, also known as slotted pipe anchor bolts, are devices used for reinforcing the surrounding rock in mine roadways. The main body is a high-strength steel pipe with longitudinal slots. A tray is movably connected to the outside of the pipe, and an anchor ring is welded to the bottom of the pipe to limit the position of the tray. When installed in a borehole slightly smaller than the pipe diameter, it applies radial pressure to the borehole wall along its entire length and resists the frictional force that prevents the surrounding rock from sliding down. Combined with the supporting force of the anchor tray, this keeps the surrounding rock in a stable state under triaxial stress. Under conditions such as blasting vibrations and rock displacement, the anchoring force will significantly increase in the later stages. Even if the surrounding rock undergoes significant displacement, the anchor bolt's support resistance will not be lost. During the anchor bolt manufacturing process, the anchor ring needs to be embedded in the outside of the anchor bolt for fixation. This step is usually completed manually after using an anchor bolt machine.

[0003] The existing pipe-seam anchor bolt machine's own anchor ring mold has a design flaw that results in the pipe-seam anchor bolt with a zero head length, which does not meet the requirement of 40-50mm head length in MT285-92 "Seamed Pipe Anchor Bolt". Furthermore, during underground use, the lack of head protection can easily cause the anchor ring to fall off, affecting safe use. Therefore, we are considering developing an embedded anchor ring mold. Utility Model Content

[0004] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0005] In view of the problems existing in the above and / or existing anchor bolt inlay ring molds for metal mines, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a mold for embedding anchor rings in anchor rods for metal mines. During use, when the spring naturally extends, the circular slider is flush with one end of the base. During operation, the anchor rod is first placed on the arc groove at the top of the fixed frame for positioning. The anchor ring is then placed on the ring magnet using magnetism. Under the action of the hydraulic cylinder, one end of the anchor rod is pushed onto the anchor ring, and the circular slider is pushed into the first inner hole. The circular slider slides backward along the slide rod. After the hydraulic cylinder resets, the circular slider moves outward under the force of the spring and pushes the anchor rod out of the first inner hole. After the anchoring is completed, stepping on the foot pedal causes the second connecting rod to rotate along the rotating axis. Through the cooperation of the second connecting rod and the first connecting rod, the first connecting rod slides upward. The first inclined block pushes the anchor rod out of the arc groove. The anchor rod rolls down the inclined surface of the first inclined block to the inclined surface of the second inclined block for guidance, so that the unloading direction is uniform. The anti-slip pad increases the friction when stepping to a certain extent, preventing slippage during the stepping process. It is convenient to collect the anchor rods uniformly for subsequent processing, eliminating the problem of anchor ring falling off during the anchor ring pressing process and the loss caused by anchor ring damage during use. It also solves the problem that the existing pipe joint anchor bolt machine itself produces pipe joint anchor bolts with zero head length due to the design defect of the anchor ring mold, which does not meet the requirement of 40-50mm head length of MT285-92 "Seamless Pipe Anchor Bolt". In addition, during underground use, the lack of head protection can easily cause the anchor ring to fall off, affecting safe use. Therefore, we considered developing an anchor ring embedding mold.

[0014] As a preferred embodiment of the anchor bolt inlay ring mold for metal mines described in this utility model, the base is fixedly connected to four corners at the bottom.

In addition, during underground use, the lack of head protection can easily cause the anchor ring to fall off, affecting safe use. Therefore, we considered developing an anchor ring embedding mold.

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0023] Example 1, please refer to Figure 1-4 This utility model provides a mold for embedding anchor rings in metal mines, including a base 1. A hydraulic cylinder 4 is fixedly connected to one side of the base 1. A push block 10 is fixedly connected to the power output end of the hydraulic cylinder 4 through one side of the base 1. A first inner hole 7 and a second inner hole 8 are respectively provided on one side of the base 1. A slide rod 9 is movably connected to one side of the second inner hole 8. A circular slider 17 is fixedly connected to one end of the slide rod 9. The circular slider 17 is movably connected to the first inner hole 7. A limit block 18 is fixedly connected to one end of the slide rod 9 through one side of the second inner hole 8. A spring 19 is provided between one side of the circular slider 17 and one side of the second inner hole 8. A ring magnet 13 is fixedly connected to one side of the first inner hole 7. A material unloading assembly is provided at the bottom of the base 1.

[0024] The base 1 has multiple fixed brackets 11 fixedly connected to its top. The top of the fixed brackets 11 is provided with arc-shaped grooves 12. Anchor rods 2 are placed between the multiple arc-shaped grooves 12. An anchor ring 3 is magnetically connected to one side of the annular magnet 13.

[0025] The first inner hole 7 has a diameter of 50 mm and a depth of 30 mm, and the second inner hole 8 has a diameter of 34 mm and a depth of 70 mm.

[0026] Specifically, when the spring 19 naturally extends, the circular slider 17 is flush with one end of the base 1. During operation, the anchor rod 2 is first placed on the arc groove 12 at the top of the fixed frame 11 for positioning. The anchor ring 3 is then placed on the ring magnet 13 using magnetism. Under the action of the oil cylinder 4, one end of the anchor rod 2 is pushed onto the anchor ring 3, and the circular slider 17 is pushed into the first inner hole 7. The circular slider 17 slides backward along the slide rod 9. After the hydraulic cylinder 4 is reset, the circular slider 17 moves outward under the force of the spring 19 and pushes the anchor rod 2 out of the first inner hole 7. After the embedding is completed, the anchor rod 2 is unloaded by the unloading assembly, which eliminates the problem of the anchor ring 3 falling off during the embedding process and the loss caused by the damage of the anchor ring 3 during use. It also solves the problem that the existing pipe joint anchor bolt machine itself produces pipe joint anchor bolts with zero head length due to design defects in the anchor ring mold, which does not meet the requirement of 40-50mm head length in MT285-92 "Seamless Pipe Anchor Bolt". In addition, during underground use, the lack of head protection can easily cause the anchor ring to fall off, affecting safe use. Therefore, we considered developing an embedding anchor ring mold.

[0027] Example 2, please refer to Figure 3 and Figure 5The unloading assembly includes a first connecting rod 5, a second connecting rod 21 is movably connected to the bottom of the first connecting rod 5, a foot pedal 23 is fixedly connected to one end of the second connecting rod 21, and an anti-slip pad is provided on the top of the foot pedal 23.

[0028] The second link 21 is horizontally fixedly connected to the rotating shaft 22 in the middle, and the third link 14 is fixedly connected to one side of the bottom of the base 1. One end of the third link 14 is provided with a through hole 15, and the rotating shaft 22 is located in the through hole 15. The second link 21 and the third link 14 are movably connected.

[0029] The top of the first connecting rod 5 passes through the bottom of the base 1 and is fixedly connected to the first inclined block 20. The second inclined block 16 is fixedly connected to one side of the base 1.

[0030] The base 1 has fixed posts 6 at each of its four bottom corners.

[0031] Specifically, after the inlay is completed, stepping on the foot pedal 23 causes the second connecting rod 21 to rotate along the rotating axis 22. Through the cooperation between the second connecting rod 21 and the first connecting rod 5, the first connecting rod 5 is driven to slide upward. The first inclined block 20 pushes the anchor rod 2 out of the arc groove 12. The anchor rod 2 rolls down the inclined surface of the first inclined block 20 to the inclined surface of the second inclined block 16 for guidance, so that the unloading direction is unified. The anti-slip mat increases the friction when stepping to a certain extent, preventing slippage during the stepping process, and facilitating the unified collection of the anchor rod 2 for subsequent processing.

[0032] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
