[0013] Furthermore, the mounting hole for the lifting device is a semi-circular hole.
[0014] Furthermore, the connecting screws are spaced out in several increments, and the connecting screw components are connected to the first disassembly block and the second frustum.
[0015] Furthermore, the center of the first disassembly block is located at the center of the second frustum.
[0016] Furthermore, the center of the first frustum is aligned with the center of the second frustum.
[0017] Compared with the prior art, the advantages and positive effects of this utility model are:

[0022] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.
[0023] The front wheel disc brake assembly is complex in structure and often weighs hundreds of kilograms, making it difficult for existing general-purpose tools to meet the requirements for efficient and safe disassembly. Traditional disassembly methods relying on manual labor and simple tools are not only extremely inefficient, with an average single disassembly taking over 6 hours, but also prone to causing varying degrees of damage to the valuable brake assembly and surrounding components due to the difficulty in precise operation, leading to a significant increase in maintenance costs. More seriously, this outdated disassembly method poses serious safety hazards, with frequent accidents resulting from parts slipping or improper tool use, posing a significant threat to the lives of miners.
[0024] The present invention will now be described in detail with reference to the accompanying drawings. This embodiment discloses a disassembly tool for the front wheel disc brake assembly of a mining dump truck, such as... Figure 1 As shown, the disassembly tool includes a disassembly tool body 1, a disassembly component 2, and a connecting screw 4. The disassembly tool body 1 includes a first frustum 11 and a second frustum 12, with the second frustum 12 disposed at the upper end of the first frustum 11. The disassembly component 2 includes a first disassembly block 21 and a second disassembly block 22. Screw holes are provided at both ends of the first disassembly block 21, and connecting screws 4 are disposed in the screw holes. A lifting device mounting hole 3 is provided on the second disassembly block 22.
[0025] The main body of the disassembly tool is disc-shaped and made of high-strength alloy steel, precision forged and CNC machined to ensure a robust structure and accurate dimensions. A semi-circular ring, made of high-quality stainless steel and hardened, is secured to the main body of the tool with six hexagonal screws on the upper surface. This ring is firmly attached to the main body and can support a lifting ring with a maximum weight of 2000 kg, facilitating lifting operations.
[0026] Disassembly component 2 is compatible with various lifting tools. The chamfered edges of the tool body fit snugly against the hollow section of the front wheel disc brake assembly of the mining dump truck, ensuring even and stable force application. The tool can be pulled by a semi-circular ring or lifted out of the assembly using a dedicated jack at the rear. The jack has a maximum lifting capacity of 4 tons and a stroke of 100 centimeters, making it flexible and convenient to operate.
[0027] The first frustum 11 and the second frustum 12 of the disassembly tool body 1 form a chamfered structure, which then fits tightly with the hollow part in the middle of the front wheel disc brake assembly, ensuring uniform and stable force application. The front wheel disc brake assembly is then lifted by hanging it on the lifting tool mounting hole 3 of the disassembly part 2, realizing the rapid disassembly of the front wheel disc brake assembly and ensuring the stability of the disassembly process. This avoids damage to the brake assembly and its surrounding components to varying degrees, effectively reducing maintenance costs and downtime, and significantly improving the maintenance efficiency and operational safety of mining dump trucks. It has extremely high practical value and broad market promotion prospects.
[0028] The center of the first disassembly block 21 is located at the center of the second frustum 12. The centers of the first frustum 11 and the second frustum 12 are aligned. The first frustum 11 and the second frustum 12 are an integrated structure, with the diameter of the first frustum 11 being larger than that of the second frustum 12. The larger diameter of the first frustum 11 creates a stepped structure on the periphery of both the first frustum 11 and the second frustum 12, allowing them to fit snugly against the front wheel disc brake assembly, ensuring even force application and facilitating the subsequent lifting of the front wheel disc brake assembly.
[0029] The upper end of the second frustum 12 is provided with a first disassembly block 21, and the second frustum 12 and the first disassembly block 21 are detachably connected. The upper end of the first disassembly block 21 is provided with a second disassembly block 22, and the second disassembly block 22 and the first disassembly block 21 are an integral structure. The first disassembly block 21 is a square block, and the second disassembly block 22 is a semi-circular block. Several screw holes are spaced apart. Several connecting screws 4 are spaced apart, and the four connecting screws connect the first disassembly block 21 and the second frustum 12.
[0030] The lifting device mounting hole 3 is a semi-circular hole. The upper surface of the semi-circular hole is curved, and the lifting device contacts the curved surface for easy lifting. Multiple connecting screws 4 are provided to ensure the stability of the connection between the first disassembly block 21 and the second truncated cone 12, improve the load-bearing capacity, and prevent it from falling during lifting. The structure of the disassembly component 2 can be adapted and adjusted to take into account the specification differences of the vertical shaft of the front wheel disc brake assembly of different vehicle models, and the size and curvature of the semi-circular structure can be flexibly changed. The lifting device mounting hole 3 is flexibly designed to be compatible with the wide variety of lifting device types on the market, and the position and diameter of the lifting device mounting hole 3 can be innovatively changed.
[0031] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
