Abstract
Description
Technical Field
[0001] This application relates to the technical field of anchor bolts, and more specifically, to an anchor bolt mixing device and its assembly and operation method. Background Technology
[0002] Anchoring agents, serving as the bonding medium between anchor bolts and the anchored rock mass, are widely used due to their excellent properties. However, limitations in anchoring structure technology prevent them from fully realizing their potential. Currently, the largest proportion of anchoring system failures is bond failure, which occurs when the anchoring agent slips between itself and the anchor hole wall, the anchoring agent and the anchor bolt surface, or a specific layer within the anchoring agent, causing the anchor bolt to be pulled out of the anchoring structure without damage. This cannot be resolved by grouting or increasing the strength of the anchor bolt material.
[0003] Therefore, improving the performance of anchoring agents and enhancing the anchoring quality between anchor bolts and rock is crucial to preventing bond failure. In recent years, both domestic and international efforts have focused on improving bonding and preventing anchoring failure by altering the shape of the anchor hole bottom and studying the waterproofing properties of anchoring agents. However, these methods have limited effectiveness and cannot fundamentally solve the following problems: 1. The centering issue of the anchor bolt; 2. The impact of polyester film packaging on anchoring performance; 3. Insufficient mixing of the polyester resin and curing agent, resulting in poor performance; 4. The problem of resin anchoring agent leakage during the installation of vertical anchor bolts. Therefore, an effective measure to improve anchoring performance is urgently needed. Summary of the Invention
[0004] One of the technical problems to be solved by this application is to overcome the technical problem of adhesion failure in the anchoring system in the prior art, and to provide a stirring device for anchor rods and its assembly and operation method.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A stirring device for an anchor bolt, comprising:
[0007] A mixing assembly, the mixing assembly including an anchoring structure and a plurality of external teeth, the plurality of external teeth being arranged circumferentially around the anchoring structure and connected to the anchoring structure, the anchoring structure being threadedly connected to an anchor rod;
[0008] A pushing assembly is located at the end of the anchor rod away from the stirring assembly, and the pushing assembly is threadedly connected to the anchor rod;
[0009] The anchor rod is configured in conjunction with the pushing component and the stirring component, so that the anchor rod is centrally positioned.
[0010] Furthermore, the first side of the external tooth is provided as an arc-shaped surface, and the arc-shaped surface is bent toward the wall of the anchor hole.
[0011] Furthermore, the external teeth are configured as an arc-shaped strip structure or a square protrusion structure.
[0012] Furthermore, when the outer teeth are designed as square protrusions, multiple outer teeth are arranged in an array on the stirring assembly.
[0013] Furthermore, when the external teeth are designed as arc-shaped strip structures, they are symmetrically arranged on the anchoring structure along the first direction.
[0014] Furthermore, the mixing assembly also includes a crushing and mixing element, which is located on the first side of the anchoring structure, and the external teeth are located on the second side of the anchoring structure;
[0015] The first side of the anchoring structure is located near the bottom of the anchoring hole, and the second side of the anchoring structure is located near the wall of the anchoring hole.
[0016] Furthermore, the pushing assembly includes:
[0017] A plugging ring section, wherein the plugging ring section is connected with helical teeth, the helical teeth being spaced apart circumferentially on the plugging ring section;
[0018] The pushing section is provided with pushing spiral teeth, which extend in a spiral shape along the axial direction of the pushing section.
[0019] The present invention also provides a method for assembling an anchor bolt stirring device, which employs the anchor bolt stirring device and includes the following steps:
[0020] After installing the mixing assembly at the top of the anchor bolt, the mixing assembly is placed into the anchor hole;
[0021] Once the bottom of the anchor hole is reached, a pushing assembly is installed at the bottom of the anchor rod.
[0022] The present invention also provides a method for operating an anchor bolt stirring device, which employs the anchor bolt stirring device.
[0023] Furthermore, it includes the following steps:
[0024] After installing the mixing assembly at the top of the anchor bolt, the mixing assembly is placed into the anchor hole;
[0025] Rotate the anchor rod to stir the anchoring agent;
[0026] The pushing component penetrates the bottom end of the anchor bolt. As the anchor bolt continues to rotate, the pushing component rotates and rises toward the anchoring end of the anchor bolt, while simultaneously squeezing the anchoring agent. This process continues until the pushing component can no longer rotate and rise, thus completing the support construction of a set of anchor bolts.
[0027] The technical solution of this invention has the following advantages:
[0028] This invention utilizes a stirring assembly that, as it rotates and rises along the threaded anchor rod, compresses and stirs the anchoring agent, ensuring thorough mixing. Upon solidification, the multiple external teeth of the assembly not only adhere to the anchoring agent but also create grooves within the solidified agent, preventing slippage due to weakened adhesion and thus protecting the anchoring support system. Conversely, the pushing assembly, as it rotates and rises along the threaded anchor rod, compresses and propels the anchoring agent, ensuring it is fully and evenly distributed between the threaded anchor rod and the anchor hole wall, enhancing the anchoring effect. Once compacted, the work is complete, and an external anchor is applied to the anchor head for further treatment, ensuring the entire anchoring support process is completed smoothly and efficiently. This invention provides equipment for uniformly mixing the anchoring agent, thoroughly breaking down and processing the plastic packaging of the anchoring agent to fully utilize its effect. Furthermore, this equipment should also ensure the anchoring agent is evenly distributed and fully fills the anchor rod and anchor hole wall, thereby improving the adhesion effect.

Detailed Implementation
[0046] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0047] like Figure 1 and Figure 2 as well as Figure 14 and Figure 5As shown, this embodiment of the invention provides a stirring device for an anchor bolt, including a stirring assembly 10 and a pushing assembly 20: the stirring assembly 10 includes an anchoring structure 11 and a plurality of external teeth 12, the plurality of external teeth 12 being arranged circumferentially around the anchoring structure 11 and connected to the anchoring structure 11, the anchoring structure 11 being threadedly connected to an anchor bolt 30; the pushing assembly 20 is located at the end of the anchor bolt 30 away from the stirring assembly 10, and the pushing assembly 20 is threadedly connected to the anchor bolt 30; wherein, the anchor bolt 30 is configured to cooperate with the pushing assembly 20 and the stirring assembly 10, so that the anchor bolt 30 is centrally positioned.
[0048] In one embodiment, a mixing assembly 10 is installed in the anchoring section of the threaded anchor bolt, and then the anchor bolt 30 installation device is used to place the mixing assembly 10 into the anchoring hole.
[0049] After preparation, the anchor rod 30 is rotated deeper. Since the mixing component 10 has a connecting cavity 141 with a threaded section, the mixing component 10 is threadedly connected to the anchor rod 30 through the connecting cavity 141. This allows the mixing component 10 to rotate with the anchor rod 30, so that the head of the mixing component 10 touches the anchoring agent. Multiple external teeth 12 can mix the anchoring agent during rotation, making it uniform. After the anchoring agent solidifies, the multiple external teeth 12 not only adhere to the anchoring agent, but also form grooves in the solidified anchoring agent. This solves the technical problem of adhesion failure in the existing anchoring system, avoids slippage hazards caused by poor adhesion, and can protect the anchoring support system.
[0050] When the bottom of the anchor hole is reached, the pushing assembly 20 is installed. The pushing assembly 20 has an installation cavity 23 and a threaded section inside the installation cavity 23. The pushing assembly 20 is threadedly connected to the anchor rod 30 through the installation cavity 23, thereby realizing the installation and fixation between the pushing assembly 20 and the anchor rod 30. By rotating the pushing assembly 20, the pushing assembly 20 can be moved forward along the anchor rod 30.
[0051] As the pushing spiral teeth 221 rotate, they prevent the adjacent anchoring agent from shifting downwards, ensuring the density of the anchoring agent. At the same time, as the plugging ring section 21 rotates and rises, the spiral teeth 211 of the plugging ring section 21 fill the previous voids, making the anchoring agent between the threaded anchor rod and the anchoring hole wall full, uniform, and dense, thus achieving the effect of strengthening the anchoring. After the voids in the anchoring agent are filled, the pushing device cannot continue to rise due to the resistance of the anchoring agent. At this time, due to the presence of the mixing component 10 and the pushing component 20, the anchor rod 30 of the anchoring section can be centered, preventing the anchor rod 30 from shifting before the anchoring agent solidifies, while ensuring the density of the anchoring agent.
[0052] In this embodiment, as the mixing component 10 rotates and rises along the threaded anchor rod, it squeezes and mixes the anchoring agent, ensuring thorough mixing. After the anchoring agent solidifies, its multiple external teeth 12 not only adhere to the anchoring agent but also create grooves within the solidified agent, preventing slippage due to poor adhesion and providing secondary protection for the anchoring support system. On the other hand, as the pushing component 20 rotates and rises along the threaded anchor rod, it squeezes and pushes the anchoring agent, ensuring the anchoring agent on the threaded anchor rod and the anchor hole wall is full and uniform, strengthening the anchoring effect. Once compacted, the work is complete, and an external anchor is applied to the anchor head for treatment, ensuring the entire anchoring support process is completed smoothly and efficiently. This embodiment provides equipment for uniformly mixing the anchoring agent, fully crushing and treating the plastic packaging of the anchoring agent to fully utilize its effect. Simultaneously, this equipment should also address the issue of uniformly distributing and fully filling the anchor rod 30 and the anchor hole wall with the anchoring agent to improve the adhesion effect.
[0053] like Figures 6 to 8 As shown and as Figures 10 to 12 As shown, in this embodiment, the first side 121 of the external tooth is set as an arc-shaped surface, and the arc-shaped surface is bent towards the wall of the anchor hole.
[0054] In this embodiment, the first side of the external tooth 12 near the wall of the anchor hole is set as an arc-shaped surface, and the direction of the arc-shaped surface is set towards the wall of the anchor hole. This arc-shaped surface structure design is conducive to the bonding of multiple external teeth 12 with the anchoring agent, and also makes the solidified anchoring agent form a groove, which improves the bonding effect between the external teeth 12 and the anchoring agent, makes the two bond more firmly, reduces the risk of slippage, and can realize secondary protection of the anchoring support system to ensure the stability of the anchoring system.
[0055] like Figures 6 to 8 As shown and as Figures 10 to 12 As shown, in this embodiment, the external teeth 12 are configured as an arc-shaped strip structure or a square protrusion structure.
[0056] like Figures 6 to 8 As shown in the embodiment, when the outer teeth 12 are configured as square protrusions, multiple outer teeth 12 are arranged in an array on the mixing assembly 10. In this embodiment, the mixing assembly with this structure is referred to as the first mixing assembly. The outer teeth 12 of the first mixing assembly are configured as square protrusions, and the sides of the protrusions (the first side 121 of the outer teeth) are arc-shaped, with the curvature pointing towards the wall of the anchoring hole. At this time, the rotation of multiple outer teeth 12 not only fully mixes the anchoring agent, ensuring uniform mixing, but also, after the anchoring agent solidifies, the multiple outer teeth 12, in addition to adhering to the anchoring agent, also create grooves in the solidified anchoring agent. This solves the technical problem of adhesion failure in the existing anchoring system, avoids slippage hazards caused by poor adhesion, and can protect the anchoring support system.
[0057] like Figures 9 to 12 As shown in the embodiment, when the external teeth 12 are set as arc-shaped strip structures, they are symmetrically arranged between each external tooth 12 on the anchoring structure 11 along the first direction X. In this embodiment, the stirring assembly with this structure is called the stirring assembly No. 2. The external teeth 12 of the stirring assembly No. 2 are set as arc-shaped strip structures, and their arc curvature is also set towards the wall of the anchoring hole. At the same time, they are symmetrically arranged between each external tooth 12 on the anchoring structure 11 along the first direction X (i.e., the axial direction of the anchoring structure 11). That is, each external tooth 12 distributed on one side of the anchoring structure 11 is symmetrically arranged with each external tooth 12 distributed on the other side of the anchoring structure 11. This structural design will generate suction at the middle position of the two sides when the threaded anchor rod rotates clockwise. The fluid anchoring agent at the upper and lower ends will be drawn into the space between the two teeth to form a vortex and be fully mixed, so that it is evenly and fully mixed between the threaded anchor rod and the wall of the anchoring hole, thereby enhancing the anchoring adhesion effect. This invention solves the technical problem of bonding failure in existing anchoring systems, avoids slippage hazards caused by poor bonding effect, and can protect the anchoring support system.
[0058] The design of these two structures allows for the selection of appropriate anchoring agent mixing components 10 for installation based on different surrounding rock conditions during the construction of this equipment. This ensures the stability of the anchoring system, greatly reduces maintenance costs, and effectively avoids the dangers caused by the failure of the anchoring support system to bond.
[0059] like Figures 6 to 8 As shown and as Figures 10 to 12 As shown, in this embodiment, the anchoring structure 11 further includes a crushing and stirring component 13, which is located on the first side 111 of the anchoring structure, and the external teeth 12 are located on the second side 112 of the anchoring structure; wherein, the first side 111 of the anchoring structure is located near the bottom end of the anchoring hole, and the second side 112 of the anchoring structure is located near the wall of the anchoring hole.
[0060] In this embodiment, on the one hand, the crushing and mixing component 13 of the anchoring structure 11 is responsible for crushing the plastic packaging of the anchoring agent at the bottom of the anchoring hole, and on the other hand, the crushing and mixing component 13 has the function of mixing the anchoring agent; at the same time, each component plays its corresponding role, so that the entire anchoring support process can be completed smoothly and efficiently.
[0061] This embodiment improves the bonding effect of the anchoring agent by ensuring uniform mixing and allowing it to react fully. Furthermore, the crushing and mixing component 13 effectively breaks down the plastic packaging of the anchoring agent into small fragments, which facilitates the mixing reaction and prevents large plastic fragments from being mixed into the anchoring agent, thus affecting the anchoring quality.
[0062] like Figure 6 and Figure 11 As shown, in this embodiment, the anchoring structure 11 includes a first anchor 14 and a second anchor 15; the first anchor 14 is connected to the external tooth 12, and the second anchor 15 is connected to the crushing and mixing component 13; wherein, one end of the first anchor 14 is connected to the second anchor 15, and the other end of the first anchor 14 is provided with a connecting cavity 141, and the first anchor 14 is threadedly connected to the anchor rod 30 through the connecting cavity 141.
[0063] In this embodiment, the first anchor 14 is a cylindrical structure with a length of 45 mm, an outer diameter of 22 mm, and a spacing of 28 mm between the two oppositely arranged external teeth 12 of the first anchor 14; the second anchor 15 is a conical structure with a height of 18 mm.
[0064] The second anchor 15 is connected to the crushing and mixing component 13 to crush the plastic packaging of the anchoring agent at the bottom of the anchoring hole and to fully mix the anchoring agent. The first anchor 14 is connected to the external teeth 12 to mix the anchoring agent during the rotation of the anchor rod, making it evenly mixed. After the anchoring agent solidifies, the multiple external teeth 12 of the second anchor 15 bond with the anchoring agent, improving the bonding effect of the anchoring agent on the anchoring system.
[0065] like Figure 6 and Figure 11 As shown, in this embodiment, the crushing and stirring component 13 includes crushing edge teeth 131 and stirring edge teeth 132; the crushing edge teeth 131 are located at the end of the second anchor 15 away from the first anchor 14; the stirring edge teeth 132 are arranged around the second anchor 15 in the circumferential direction and are connected to the second anchor 15.
[0066] In this embodiment, the crushing edge tooth 131 is used to crush the plastic packaging of the anchoring agent at the bottom of the anchoring hole, and the stirring edge tooth 132 has the function of mixing the anchoring agent.
[0067] This embodiment solves the problem that existing anchor bolts do not respond well to the breakage of anchoring agent packaging bags, contain large fragments, affect the mixing of anchoring agent, and cause the anchoring agent to not react fully, thereby reducing the adhesion effect of the anchoring agent to the anchoring system. This embodiment improves the adhesion effect of the anchoring agent to the anchoring system by mixing the anchoring agent evenly, allowing the anchoring agent to react fully.
[0068] like Figures 2 to 4 As shown, in this embodiment, the pushing assembly 20 includes a blocking ring section 21 and a pushing section 22; the blocking ring section 21 is connected with helical teeth 211, which are spaced apart around the circumference of the blocking ring section 21; the pushing section 22 is provided with pushing helical teeth 221, which extend in a helical shape along the axial direction of the pushing section 22; wherein, the lead of the pushing helical teeth 221 can be set to 4mm.
[0069] In this embodiment, the length of the pushing component 20 along its axial direction is set to 16 mm, the length of the plugging ring section 21 along its axial direction is set to 2 mm, and the maximum outer diameter of the pushing component 20 along the direction perpendicular to its axial direction is set to 28 mm.
[0070] In this embodiment, as the pushing section 22 rotates, the pushing spiral teeth 221 prevent adjacent anchoring agents from shifting downwards, ensuring the density of the anchoring agents. At the same time, as the blocking ring section 21 rotates and rises, the spiral teeth 211 of the blocking ring section 21 fill the previous voids, making the anchoring agents between the threaded anchor rod and the anchoring hole wall full, uniform, and dense, thus achieving the effect of strengthening the anchoring. After the voids in the anchoring agents are filled, the pushing device cannot continue to rise due to the resistance of the anchoring agents. At this time, due to the presence of the stirring component 10 and the pushing component 20, the anchor rod 30 of the anchoring section can be centered, preventing the anchor rod 30 from shifting before the anchoring agents solidify, while ensuring the density of the anchoring agents.
[0071] In this embodiment, the combined action of the spiral teeth 211 and the pushing spiral teeth 221 designed on the pushing component 20 achieves a full, uniform, and dense anchoring effect between the threaded anchor rod and the anchor hole wall, thus enhancing the anchoring effect. This solves the technical problems in the prior art where the mixed anchoring agent easily leads to uneven bonding between the anchor hole wall and the anchor rod, resulting in voids; and the inability to evenly distribute the anchoring agent at the bottom of the anchor hole between the anchor rod and the anchor hole wall.
[0072] like Figure 13 and Figure 14 As shown, this embodiment of the invention provides an assembly method for an anchor bolt stirring device, which employs an anchor bolt stirring device and includes the following steps:
[0073] like Figure 13 As shown, after installing the mixing assembly 10 at the top of the anchor bolt 30, the mixing assembly 10 is placed into the anchor hole.
[0074] like Figure 14 As shown, after reaching the bottom of the anchor hole, the pushing component 20 is installed at the bottom of the anchor rod 30.
[0075] In one embodiment, the mixing assembly 10 is installed and fixed at the anchoring section at the top of the threaded anchor rod; then the mixing assembly 10 is placed into the anchoring hole using the anchor rod 30 installation device.
[0076] After preparation is complete, start rotating the anchor rod 30 to go deeper. Stop when it reaches the bottom of the anchor hole. Install the pushing component 20 to ensure that the anchor rod 30 is always in the center position and does not shift.
[0077] In this embodiment, the anchor rod 30 and the mixing component 10 first work together to break the plastic packaging of the anchoring agent and mix and fill the anchoring agent. When the mixing component 10 reaches the bottom of the anchoring hole, the pushing component 20 is installed at the bottom of the anchor rod 30. As the pushing component 20 rotates and rises, the anchoring agent is compacted. The anchor rod 30, the mixing component 10 and the pushing component 20 work together to complete a set of anchoring support processes.
[0078] This embodiment is simple to install and easy to operate. It can efficiently mix the anchoring agent, and the device can make the anchoring agent completely and evenly mixed, so as to maximize its bonding effect and ensure the effectiveness of the anchoring system.
[0079] like Figure 13 and Figure 14 As shown, this embodiment of the invention provides a method for operating an anchor bolt mixing device, which employs an anchor bolt mixing device. The method includes the following steps:
[0080] After installing the mixing component 10 at the top of the anchor bolt 30, the mixing component 10 is placed into the anchoring hole; the anchor bolt 30 is rotated to mix the anchoring agent; when it reaches the bottom of the anchoring hole, the pushing component 20 is installed at the bottom of the anchor bolt 30. Specifically, the bottom of the anchor bolt 30 is inserted through the installation cavity 23 of the pushing component 20, and through the bottom of the anchor bolt 30; the pushing component 20, passing through the anchor bolt 30, moves towards the anchoring end of the anchor bolt 30 with the help of the rotational force of the anchor bolt 30, so as to squeeze the anchoring agent until the pushing component 20 compacts the anchoring agent. At this time, the pushing component 20 can no longer rotate and rise, and the support construction of a set of anchor bolts 30 is completed.
[0081] In one embodiment, the mixing assembly 10 is installed and fixed in the anchoring section of the threaded anchor bolt; then the anchor bolt 30 installation device is used to place the mixing assembly 10 into the anchoring hole.
[0082] After preparation, the anchor rod 30 is rotated deeper, allowing the head of the anchoring agent mixing device to touch the anchoring agent. The anchoring agent is then mixed within the anchoring hole, and each component performs its corresponding function, ensuring the entire anchoring support process is completed smoothly and efficiently. The process ends at the bottom of the anchoring hole, where the pushing component 20 is installed. This device ensures the anchor rod 30 remains centered and does not shift. As it rotates and rises along the threaded anchor rod, it squeezes and pushes the anchoring agent, ensuring the anchoring agent between the threaded anchor rod and the anchoring hole wall is full and uniform, strengthening the anchoring effect. Once compacted, the work is complete. Finally, an external anchor is applied to the anchor head for treatment, completing the support construction for one set of anchor rods 30.
[0083] Installing the pushing component 20 ensures that the anchor bolt 30 remains centered and does not shift. As it rotates and rises along the threaded anchor bolt, it squeezes and pushes the anchoring agent, making the anchoring agent between the threaded anchor bolt and the wall of the anchoring hole full and uniform, thus strengthening the anchoring effect. Once it is compacted, the work is completed. Then, an external anchor is applied to the anchor head for treatment, and the support construction of one set of anchor bolts 30 is completed.
[0084] This embodiment can uniformly stir the anchoring agent and fully crush the plastic packaging of the anchoring agent, which greatly improves the anchoring effect. At the same time, this device can also solve the problem of uniformly distributing the anchoring agent and filling it fully in the anchor rod and the wall of the anchor hole, thereby improving the bonding effect. This device can maximize the bonding performance of the anchoring agent and avoid overuse.
[0085] In summary, the present invention provides a stirring device for an anchor bolt, comprising: a stirring assembly 10 and a pushing assembly 20; the stirring assembly 10 is provided with an anchoring structure 11, the anchoring structure 11 including external teeth 12, the external teeth 12 being arranged in an array on the stirring assembly 10, the external teeth 12 being arranged around the stirring assembly 10 in a circumferential direction and connected to the stirring assembly 10, and the stirring assembly 10 being threadedly connected to the anchor bolt 30; the pushing assembly 20 is located at the end of the anchor bolt 30 away from the stirring assembly 10, and the pushing assembly 20 is threadedly connected to the anchor bolt 30; wherein, the anchor bolt 30 is configured to cooperate with the pushing assembly 20 and the stirring assembly 10, so that the anchor bolt 30 is centrally located.
[0086] In this invention, an anchor support system is formed by a mixing assembly 10, a pushing assembly 20, and a threaded anchor rod. The mixing assembly 10 is responsible for breaking up the plastic packaging of the anchoring agent during the advancement process and mixing the anchoring agent to fully utilize its bonding properties. During the anchoring process, when the anchor rod assembly device rotates and rises, it ensures that the threaded anchor rod is always in the centered position, preventing displacement before the anchoring agent solidifies. The accompanying compression action ensures that the anchor hole wall is tightly sealed with the anchoring agent in the mixing assembly. The threaded anchor rod is formed by the mixing assembly 10 and the pushing assembly 20, which implement prestress and install and fix the anchoring agent. The mixing assembly 10 includes mixing teeth 132, external teeth 12, and a connecting cavity 141 for breaking the teeth 131. The crushing edge tooth 131 is mainly responsible for crushing the plastic packaging of the anchoring agent, and also plays a role in the initial mixing of the anchoring agent; the mixing edge tooth 132 is mainly responsible for mixing the anchoring agent to make it uniform; the internal thread of the connecting cavity 141 mates with the thread of the anchor rod, and is responsible for installation and fixation, so that the anchoring agent mixing device rotates with the anchor rod; the external tooth 12 can also continue to mix the anchoring agent during rotation. After the anchoring agent solidifies, its multiple external teeth, in addition to adhering to the anchoring agent, will also form grooves in the solidified anchoring agent, avoiding the slippage hazard caused by poor adhesion, and can be used as secondary protection in the anchoring support system. The pushing assembly 20 includes a helical tooth 211, a pushing helical tooth 221, and an installation cavity 23. The internal thread of the installation cavity 23 engages with the thread of the 9 anchor rod, which is responsible for installation and fixation, allowing the device to advance along the anchor rod. This equipment also keeps the anchor rod in a centered position, preventing the anchor rod from shifting before the anchoring agent solidifies. As the pushing helical tooth 221 rotates, it prevents the adjacent anchoring agent from shifting downward, ensuring the density of the anchoring agent. At the same time, due to the rotation and rise of the helical tooth 211, the previous voids are filled, making the anchoring agent between the 3-threaded anchor rod and the anchor hole wall full, uniform, and dense, strengthening the anchoring effect. After the voids of the anchoring agent are filled, the pushing device cannot continue to rise due to the resistance of the anchoring agent. At this time, due to the presence of the stirring device and the pushing device, the anchor rod in the anchoring section can be centered, while ensuring the density of the anchoring agent. The lead of the pushing helical tooth 221 is 4mm. In addition, the mixing component 10 of the present invention can also be designed with another structure, where only the outer teeth 12 of the mixing component 10 are designed as an arc-shaped strip-shaped mixing paddle structure. This mixing component 10 with the mixing paddle structure is referred to as the mixing component number two in the present invention. It is mainly responsible for fully mixing the anchoring agent. As the threaded anchor rod rotates clockwise, it generates suction in the middle, drawing the fluid anchoring agent at both ends into the space between the two teeth for thorough mixing. This ensures that the agent is evenly and fully mixed between the threaded anchor rod and the wall of the anchoring hole, enhancing the anchoring adhesion effect. This design allows for the selection of a suitable anchoring agent mixing component 10 for installation based on different surrounding rock conditions during the construction of this equipment. The stability of the anchoring system is guaranteed, maintenance costs can be greatly reduced, and the danger caused by the failure of the anchoring support system adhesion can be effectively avoided.
[0087] This invention can uniformly stir the anchoring agent and fully break the plastic packaging of the anchoring agent, thereby improving the anchoring effect. At the same time, it can also make the anchoring agent evenly distributed and fully fill the anchor rod and the wall of the anchor hole, thus improving the bonding effect.
[0088] This invention also provides a mixing device for anchor bolts and its assembly and operation method. First, assembly is performed: depending on the surrounding rock conditions, either a mixing component or a second mixing component can be installed and fixed in the anchoring section of the threaded anchor bolt; then, the anchor bolt installation device is used to place it into the anchoring hole. Second, operation begins: after preparation, the anchor bolt is rotated deeper, allowing the head of the anchoring agent mixing device to touch the anchoring agent. The anchoring agent is then mixed within the anchoring hole, and each component performs its corresponding function, ensuring the entire anchoring support process is completed smoothly and efficiently. When the bottom of the anchoring hole is reached, the anchor bolt assembly device is installed. This device ensures the anchor bolt remains centered and does not shift. As it rotates and rises along the threaded anchor bolt, it compresses and propels the anchoring agent, ensuring the anchoring agent between the threaded anchor bolt and the anchoring hole wall is full and uniform, strengthening the anchoring effect. Once compacted, the work is complete. Finally, an external anchor is applied to the anchor head for treatment, completing the anchor bolt support construction for one set.
