Description

Technical Field

[0001] The utility model relates to the field of coal mine roadway support, and particularly to a waterproof device for an anchor bolt fixing system. More specifically, the utility model discloses a waterproof bowl-shaped anchor bolt tray for improving the waterproof performance and service life of the anchor bolt system in a water-rich environment. Background Art

[0002] The anchor bolt fixing technology is widely used in fields such as geotechnical engineering, tunnel engineering, and mine engineering for reinforcing rock masses, soil bodies, or concrete structures. Traditional anchor bolt fixing systems usually include components such as anchor bolts, anchoring agents, trays, and locks. Among them, the tray is an important component connecting the end of the anchor bolt to the fixed surface, playing a role in dispersing stress and protecting the anchoring point. However, existing anchor bolt trays generally have deficiencies in terms of end waterproof performance and structural design. The main problems include: Flat design: Most existing trays adopt a simple flat or slightly convex design, which cannot effectively guide water flow away from the end of the anchor bolt and is prone to water accumulation. Insufficient end sealing: The connection between the end of the anchor bolt and the tray often lacks effective sealing measures, resulting in easy infiltration of moisture from here. Material limitations: Some tray materials are prone to corrosion or aging in a water-rich environment, affecting the service life and sealing effect. Lack of drainage function: Existing trays usually do not have a special drainage design and cannot quickly drain the water accumulated at the end of the anchor bolt. Fragile structure: Many existing designs do not consider the pressure generated when the anchor bolt lock is tightened, easily causing damage to the sealing ring or the tray body. Unreasonable force transmission: In some designs, the force when the anchor bolt lock is tightened directly acts on the plastic structure or the sealing ring, reducing the durability and reliability of the system. These problems may lead to the following consequences: Deterioration of anchoring point performance: Moisture infiltration from the end will affect the strength and durability of the anchoring point. Corrosion of the anchor bolt end: The continuous water-rich environment will accelerate the corrosion process of the anchor bolt end and reduce its service life. Local structural degradation: Moisture penetration may cause a reduction in the local strength of the structure around the anchor bolt end. Increased maintenance costs: Insufficient end waterproof performance will increase the maintenance frequency and cost of the system. Damage to the sealing ring: The sealing ring may be crushed when the anchor bolt lock is tightened, resulting in waterproof failure. Rupture of the plastic structure: Excessive pressure may cause the plastic bowl-shaped structure to rupture, affecting the overall waterproof performance. In view of the above problems, it is of great practical significance to develop an anchor bolt tray with excellent end waterproof performance and a reasonable force transmission structure. An ideal design should not only effectively protect the key end of the anchor bolt but also protect the sealing ring and plastic structure from damage when the anchor bolt lock is tightened. The utility model aims to solve the deficiencies in the prior art and provide a bowl-shaped anchor bolt tray with a reasonable structure, remarkable end waterproof effect, and an innovative force transmission design. This design effectively protects the sealing ring and the plastic bowl-shaped structure from excessive pressure when the anchor bolt lock is tightened by setting a special structure outside the sealing ring, while improving the protection ability of the end of the anchoring system in a water-rich environment and the overall durability.

[0025] The following will further describe the present invention in detail with reference to the drawings.

[0026] As Figure 1 , Figure 2 shown, the waterproof tray at the end of the bolt provided by the utility model is an improved design based on the original bolt tray. This design mainly consists of a bowl-shaped structure (1), a metal reinforcement plate (4) and a polyurethane sealing ring (3). These three components are combined in a specific way to form an integral waterproof structure.

[0027] The bowl-shaped structure (1) is made of high-strength waterproof material and is the outer layer of the entire device. Multiple annularly distributed drainage grooves (2) are provided at its edge for quickly discharging the moisture that may seep in. A metal reinforcement plate (4) is embedded inside the bowl-shaped structure, and the two are firmly combined through a connection structure (5). The metal reinforcement plate (4) not only enhances the overall structural strength but also provides a stable installation foundation for the internal polyurethane sealing ring (3).

[0028] A polyurethane sealing ring (3) is installed at the center of the metal reinforcement plate (4). This sealing ring is made of polyurethane and can closely fit with the bolt rod body (7). A central hole (8) is provided at the center of the entire structure for the bolt rod body (7) to pass through.

[0029] The working principle of the present utility model is as follows:

[0030] The working principle of the waterproof tray at the end of the bolt of the present utility model is mainly reflected in its multi-layer structure design and special installation method. As Figure 2 shown, during actual installation, this waterproof tray is placed on top of the original bolt tray (9), and the bolt rod body (7) sequentially passes through the original bolt tray (9), the central hole (8) of this waterproof tray, and the polyurethane sealing ring (3). The entire device is fixed on the bolt rod body (7) through a lock (6), and at the same time, the original bolt tray (9) and this waterproof tray are pressed tightly. This installation method forms a multi-layer waterproof structure from the outside to the inside: the bowl-shaped structure (1) serves as the first line of defense to block most of the moisture, and the drainage grooves (2) at its edge can quickly discharge the accumulated moisture; the internal metal reinforcement plate (4) evenly disperses the pressure when the lock is tightened to keep the structure stable; the innermost polyurethane sealing ring (3) is in direct contact with the bolt rod body (7) and deforms under pressure to adapt to the surface of the rod body, forming a tight waterproof barrier.

[0031] During actual work, when moisture seeps in from the environment, it will be gradually blocked and discharged by this multi-layer structure. The bowl-shaped structure first blocks and guides the moisture to the drainage grooves, and a small amount of infiltrated moisture is further blocked by the metal reinforcement plate and the polyurethane sealing ring. The double pressing effect of the lock ensures the tightness of the entire system and further enhances the waterproof effect. The original bolt tray and the newly added waterproof tray work together to form a double protection, and can continue to play a role even in a long-term humid environment, effectively protecting the bolt system from moisture erosion. This design not only improves the waterproof effect but also realizes simple and efficient installation and maintenance through compatibility with the original system, and is applicable to various humid or waterlogged environments.

[0032] The installation process is simple and intuitive: First, place the bowl-shaped structure (1) (already assembled with the metal reinforcement plate (4)) above the original anchor bolt tray (9) to ensure central alignment. Then, place the polyurethane sealing ring (3) at the center of the metal reinforcement plate (4). Next, pass the anchor bolt rod body (7) through the entire structure, and finally fix and tighten it with the lock (6) so that the polyurethane sealing ring (3) fits tightly against the anchor bolt rod body (7).

[0033] This design not only improves the waterproof performance of the anchoring system but also maintains compatibility with the existing system. It is applicable to anchoring systems in various water-rich environments, such as tunnels, underground projects, mines, etc., without significant modification to the original equipment, and has high practical value and broad application prospects.

[0034] The utility model is applicable to anchoring systems in various water-rich environments, such as tunnels, underground projects, mines, etc. It not only improves the waterproof performance of the anchoring system but also maintains compatibility with the existing system, without significant modification to the original equipment, and has high practical value and broad application prospects.

[0035] In addition, the design of the utility model also has good maintainability. If it is found that the polyurethane sealing ring (3) is aging or damaged, the lock (6) can be easily disassembled to replace the new sealing ring without replacing the entire device. This modular design greatly improves the service life and economy of the product.

[0036] In summary, through innovative structural design and material selection, the utility model effectively solves the deficiencies of the existing anchor bolt tray in terms of waterproof performance and structural strength, providing a simple, effective, and easy-to-implement solution for the waterproof performance of the anchoring system.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the utility model and are not used to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described above or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
