Description

Technical Field

[0001] This utility model relates to the field of grouting anchor technology, and in particular to a grouting anchor with a reinforcement structure for mine area management. Background Technology

[0002] In engineering fields such as mine area management, slope reinforcement, and tunnel excavation, grouting anchors serve as a crucial support structure, with their stability and reinforcement effect directly impacting the safety and reliability of the project. However, traditional grouting anchor designs often suffer from problems such as poor reinforcement effect and easy loosening, especially under complex geological conditions, where their stability and durability face severe challenges.

[0003] Furthermore, while there are many types of grouting anchors on the market, most suffer from complex operation and difficult maintenance. Many grouting anchors are overly complex in design, with cumbersome installation and commissioning processes, increasing construction difficulty and cost, and making them prone to malfunction or damage during use. In addition, some grouting anchors also face numerous difficulties in maintenance and replacement, such as inconvenient disassembly and easy loss of parts. All of these negatively impact the safety and efficiency of the project. Therefore, we have developed a grouting anchor with a reinforced structure for mine area remediation. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a grouting anchor bolt with a reinforced structure for mine area management, solving the problems mentioned in the background technology.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a grouting anchor bolt with a reinforced structure for mine area management, comprising: an anchor bolt body and a conical drill bit fixedly installed at the lower end of the anchor bolt body, a pad plate fixedly installed on the periphery of the anchor bolt body, a threaded groove opened on the periphery of the anchor bolt body, and a reinforced structure connected to the periphery of the anchor bolt body;

[0006] The reinforcement structure includes a sleeve pipe fixedly installed around the periphery of the anchor bolt body. A strip-shaped groove is vertically formed on the periphery of the sleeve pipe. A rotating abutment rod is rotatably connected to the inner wall of the strip-shaped groove via a pivot, which is used to unfold and abut against the inner wall of the anchor hole. A sliding rod is slidably connected to the inner wall of the strip-shaped groove, and an abutment ball is fixedly connected to the end of the sliding rod. A guide structure connects the strip-shaped groove and the sliding rod.

[0007] The anchor bolt body is connected to a pushing component for triggering the sliding rod to move.

[0008] As a further technical solution of this utility model, the pushing component includes an annular disk sleeved around the anchor rod body and a through hole opened on the surface of the pad. A pushing rod is fixedly connected to the lower end surface of the annular disk for pushing the sliding rod to move downward. A nut is threadedly sleeved around the periphery of the anchor rod body through a threaded groove and is designed to be located on the upper end surface of the annular disk.

[0009] As a further technical solution of this utility model, the guide slide structure includes a guide slide groove formed on the inner side wall of the strip groove, a guide slide block is slidably connected to the inner wall of the guide slide groove, and the opposing surfaces of the two guide slide blocks are fixedly connected to the side of the sliding rod.

[0010] As a further technical solution of this utility model, a second nut is threadedly connected to the outer periphery of the anchor rod body through a threaded groove, and the second nut is located between the pad and the annular disc to support the annular disc. A grout stop plug is fixedly connected to the lower end of the pad, and the grout stop plug is sleeved on the outer periphery of the anchor rod body.

[0011] As a further technical solution of this utility model, two grout outlet holes are respectively opened from top to bottom on the periphery of the anchor bolt body, and a second grout outlet hole is opened on the periphery of the conical drill bit. The first and second grout outlet holes are used for the subsequent discharge of grout.

[0012] As a further technical solution of this utility model, a spring is fixedly connected to the inner bottom wall of the strip groove, and one end of the spring is fixedly connected to the rotating abutment rod, so that the rotating abutment rod can be reset when it is not resisted by the abutment ball.

[0013] As a further technical solution of this utility model, the lower end of the push rod passes through the through hole and abuts against the upper surface of the sliding rod, and the inner diameter of the through hole is adapted to the outer diameter of the push rod.

[0014] As a further technical solution of this utility model, the contact ball is connected to the rotating contact rod and is used to contact the rotating contact rod to generate an unfolding. There are a total of four rotating contact rods.

[0015] This utility model provides a grouting anchor bolt with a reinforced structure for mine area treatment, which has the following advantages compared with the prior art:

[0016] 1. This design presents a grouting anchor bolt with a reinforced structure for mine area remediation. Through the design of the reinforced structure, including components such as a sleeve, a strip groove, a rotating abutment rod, a sliding rod, and an abutment ball, the grouting anchor bolt is effectively reinforced during the grouting process. When the grouting anchor bolt is injected into the anchor hole, the sliding rod and the abutment ball move downwards by the pushing components, abutting and unfolding the rotating abutment rod, making it in close contact with the inner wall of the anchor hole. This design not only increases the contact area between the grouting anchor bolt and the inner wall of the anchor hole but also provides additional fixing force through the unfolding of the rotating abutment rod, thereby significantly improving the stability of the grouting anchor bolt. This is of great significance for applications requiring high stability, such as mine area remediation.

[0017] 2. This design presents a grouting anchor bolt with a reinforced structure for mine area remediation. All components of the reinforced structure are achieved through simple mechanical connections and sliding fits, eliminating the need for complex installation and commissioning processes. Furthermore, the use of standard parts such as threaded grooves and nuts for connection and fixation makes maintenance and replacement of the grouting anchor bolt more convenient. In addition, the contact connection method between the contact ball and the rotating contact rod ensures the reliability and stability of the reinforced structure, making the grouting anchor bolt less prone to failure or damage during use.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a grouting anchor bolt with a reinforced structure for mine area remediation, mainly comprising an anchor bolt body 1 and a conical drill bit 2 fixedly installed at the lower end of the anchor bolt body 1. A pad 3 is fixedly installed on the periphery of the anchor bolt body 1 to provide a support surface during grouting. A threaded groove 18 is also provided on the periphery of the anchor bolt body 1 to facilitate subsequent connection with other components. Crucially, a reinforcing structure is connected to the periphery of the anchor bolt body 1. This reinforcing structure includes a sleeve pipe 4 fixedly installed on the periphery of the anchor bolt body 1. A strip-shaped groove 5 is vertically formed on the periphery of the sleeve pipe 4. A rotating abutment rod 7 is rotatably connected to the inner wall of the strip-shaped groove 5 via a pivot. These rotating abutment rods 7, when unfolded, can abut against the inner wall of the anchor hole, enhancing the anchor bolt's fixing effect. A sliding rod 6 is also slidably connected to the inner wall of the strip-shaped groove 5. An abutment ball 8 is fixedly connected to the end of the sliding rod 6 to push the rotating abutment rod 7 to unfold under specific conditions.

[0025] like Figure 1-4 As shown, the pushing component is an important part of the present invention. It includes an annular disc 9 sleeved around the periphery of the anchor rod body 1 and a through hole 10 formed on the surface of the pad 3. A pushing rod 11 is fixedly connected to the lower end surface of the annular disc 9. When the annular disc 9 is pushed downward, the pushing rod 11 passes through the through hole 10 and abuts against the upper end surface of the sliding rod 6, thereby pushing the sliding rod 6 to move downward. A nut 12 is also threadedly sleeved around the periphery of the anchor rod body 1 through a threaded groove 18 to fix the position of the annular disc 9. When the nut 12 is tightened, the annular disc 9 and the pushing rod 11 work together to push the sliding rod 6 and the abutting ball 8 downward, thereby triggering the unfolding of the rotating abutting rod 7.

[0026] like Figure 1-4 As shown, the guide structure is used to ensure the smooth sliding of the sliding rod 6 within the strip groove 5. It includes a guide groove 14 formed on the inner wall of the strip groove 5, and a guide block 15 slidably connected to the inner wall of the guide groove 14. The opposing surfaces of the two guide blocks 15 are fixedly connected to the side of the sliding rod 6. The cooperation between the guide structure and the guide blocks 15 makes the sliding rod 6 more stable during movement and less prone to deviation or jamming.

[0027] like Figure 1-4As shown, in order to support the annular disc 9 and provide additional fixing force, a second nut 16 is threadedly fitted onto the periphery of the anchor body 1 through a threaded groove 18, and the second nut 16 is positioned between the pad 3 and the annular disc 9. A grout stop plug 17 is also fixedly connected to the lower end of the pad 3 to prevent grout leakage during the grouting process; the combined use of the second nut 16 and the grout stop plug 17 further enhances the stability and grouting effect of the grouting anchor.

[0028] like Figure 1-4 As shown, in order to ensure the uniform distribution and effective injection of grout, two grout outlet holes 19 are opened from top to bottom on the outer periphery of the anchor bolt body 1, and a grout outlet hole 20 is also opened on the outer periphery of the conical drill bit 2; during the grouting process, the grout can flow out evenly through the grout outlet holes 19 and grout outlet holes 20, so as to achieve effective treatment of the mining area.

[0029] like Figure 1-4 As shown, in order to ensure that the rotating abutment rod 7 can automatically reset when it is not abutted by the abutment ball 8, a spring 13 is fixedly connected to the inner bottom wall of the strip groove 5, and one end of the spring 13 is fixedly connected to the rotating abutment rod 7; when the abutment ball 8 no longer abuts the rotating abutment rod 7, the elastic force of the spring 13 will cause the rotating abutment rod 7 to automatically reset, which facilitates the subsequent grouting operation.

[0030] like Figure 1-4 As shown, the lower end of the push rod 11 passes through the through hole 10 and abuts against the upper surface of the sliding rod 6, and the inner diameter of the through hole 10 is matched with the outer diameter of the push rod 11. This design ensures that the push rod 11 can accurately and stably push the sliding rod 6 downward, thereby triggering the unfolding of the rotating abutment rod 7.

[0031] like Figure 1-4 As shown, the contact ball 8 is connected to the rotating contact rod 7 and is used to abut against the rotating contact rod 7 to generate an unfolding effect. There are four rotating contact rods 7 in total to provide a more uniform reinforcement effect; when the contact ball 8 moves down and abuts against the rotating contact rod 7, the four rotating contact rods 7 will unfold simultaneously, forming a tighter contact with the inner wall of the anchor hole, thereby providing a stronger reinforcement effect.

[0032] The working principle of this utility model is as follows: the anchor body 1 is drilled into the anchor hole through the conical drill bit 2; the pad 3 is close to the anchor hole opening to provide support for the grouting process; the sleeve 4 is fixed on the periphery of the anchor body 1, and a rotating abutment rod 7 is rotatably connected in the strip groove 5 on it. These rotating abutment rods 7 are kept in the initial contracted state under the action of the spring 13.

[0033] The sliding rod 6 and its end contact ball 8 are located in the strip groove 5 and are kept sliding smoothly by the guide slide groove 14 and guide slide block 15; the second nut 16 is threaded onto the threaded groove 18 of the anchor rod body 1 and is located between the pad 3 and the annular disk 9 to support the annular disk 9; the first nut 12 is also threaded onto the threaded groove 18 of the anchor rod body 1 and its position is adjusted so that it is on the upper surface of the annular disk 9 to prepare for subsequent grouting operations;

[0034] Once the grouting anchor is ready, the annular disc 9 is pushed downwards using external tools or equipment. The pushing rod 11 at the lower end of the annular disc 9 passes through the through hole 10 of the pad 3 and abuts against the upper surface of the sliding rod 6. As the annular disc 9 continues to move downwards, the pushing rod 11 pushes the sliding rod 6 to slide downwards along the strip groove 5. The abutting ball 8 at the end of the sliding rod 6 moves accordingly and abuts against the rotating abutting rod 7. Under the action of the abutting ball 8, the rotating abutting rod 7 rotates around the axis and unfolds, abutting against the inner wall of the anchor hole, thereby achieving the reinforcement effect.

[0035] After the reinforcement structure is fully deployed, grout is injected into the grout outlet hole 19 of the anchor body 1 and the grout outlet hole 20 of the conical drill bit 2 through the grouting equipment; the grout stop plug 17 is located at the lower end of the pad plate 3 and is sleeved around the anchor body 1 to prevent grout leakage.

[0036] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
