Detailed Implementation

[0029] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings.

[0030] like Figure 1-14 As shown, this mining truck rotor and brake caliper replacement vehicle is a specialized piece of equipment for replacing rotors and brake calipers on mining trucks. Its design aims to provide a stable, flexible, and efficient working platform. The entire vehicle is built on a frame 1, with tracked wheels 9 mounted at the bottom to increase friction with the ground, reduce damage to concrete surfaces, and ensure good mobility and stability on various complex terrains. A vertical swing arm 2 is mounted on the frame 1, and its forward and backward swing is controlled by a vertical swing arm cylinder 21 to adjust the working height. A horizontal telescopic arm 3 is mounted on the vertical swing arm 2, and a horizontal swing arm cylinder 31 is located between the horizontal telescopic arm 3 and the vertical swing arm 2 to control the horizontal telescopic arm 3's pitch around the vertical swing arm 2. Simultaneously, a telescopic arm cylinder 32 is located within the horizontal telescopic arm 3 to control the forward and backward movement of the front angle fine-tuning device 4, thereby achieving multi-dimensional operational adjustments and further improving work accuracy. Additionally, an instrument switch 10 and a lighting signal device 11 are also mounted on the frame.

[0031] like Figure 6 , 11 As shown, the angle fine-tuning device 4 consists of a fixed plate 41, a hinged plate 42, and a front mounting plate 43. The fixed plate 41 is fixed to the end of the horizontal telescopic arm 3. One end of the hinged plate 42 is hinged to the fixed plate 41, and the other end is hinged to the front mounting plate 43. Fine angle adjustments are made through the pitch adjustment cylinder 44 and the horizontal angle adjustment cylinder 45 to ensure that the tooling can be accurately aligned with the target part. The front mounting plate 43 is equipped with a slewing support 7, which is driven by a worm gear connection. Replaceable rotor removal tooling 5 and brake caliper removal tooling 6 are installed on it to adapt to different types of maintenance tasks.

[0032] like Figure 1 , 2As shown in Figures 5, 6, and 9, the rotor disassembly fixture 5 includes a first fixed mounting shell 51, a first driving gear 52 housed inside, a first driven gear 53 arranged in an outer circular array, and a disassembly screw 54. The first driven gear 53 is fixedly mounted inside the first fixed mounting shell 51 via a first mounting shaft 55. One end of the first mounting shaft 55 penetrates the first fixed mounting shell 51 and is fixedly connected to the slewing support 7. The other end of the first mounting shaft 55 is fixedly mounted with the disassembly screw 54. A drive hydraulic motor 8 is also provided on the front mounting plate 43. The first driving gear 52 is driven by the drive hydraulic motor 8, and the first driven gear 53 meshes with the first driving gear 52. The rotation of each gear is controlled by the drive hydraulic motor 8, thereby controlling the tight connection between the disassembly screw 54 and the mining truck rotor 12, ultimately realizing the automated disassembly process of the rotor, reducing manual intervention and improving work efficiency.

[0033] Similarly, as Figure 10 , 11 As shown in Figure 12, the brake caliper disassembly fixture 6 includes a second fixed mounting housing 61, a second driving gear, a second driven gear, a screw remover 64, a brake caliper clamp cylinder 65, and a brake caliper clamp 66. The second driving gear and the second driven gear have the same connection structure as the first driving gear and the first driven gear. The second mounting shaft has the same structure as the first mounting shaft, so it is not shown in the attached figure. A drive hydraulic motor 8 is also provided on the front mounting plate 43. The drive hydraulic motor 8 is connected to the second driving gear. The second driving gear is housed in the second fixed mounting housing 61. Several second driven gears are distributed in an array on the outer circle of the second driving gear. The second driven gears are fixedly mounted in the second fixed mounting housing 61 through the second mounting shaft. One end of the second mounting shaft penetrates the second fixed mounting housing 61 and is fixedly connected to the slewing support 7. The other end of the second mounting shaft is fixedly mounted with the screw remover 64. The brake caliper clamp cylinder 65 and the brake caliper clamp 66 are mounted on the second fixed mounting housing 61. The brake caliper clamp 66 is driven by the brake caliper clamp cylinder 65. This system is also driven by a hydraulic motor 8, specifically designed for the removal or installation of the mine truck brake caliper 13, ensuring operational safety and accuracy. Overall, this design not only improves the quality and speed of maintenance but also significantly enhances the operating efficiency of mine transport vehicles, reduces labor intensity, and provides strong support for mining operations.

[0034] The working principle and process of this utility model are as follows:

[0035] The present invention relates to a mining truck rotor and brake caliper replacement vehicle. When a mining truck rotor 12 needs repair, the operator first installs the mining truck rotor disassembly fixture 5 on the replacement vehicle and then drives directly to the destination. The operator uses remote control to drive the vertical swing arm 2 and the horizontal telescopic arm 3 to reach the required disassembly / reassembly height. Then, the operator remotely controls the slewing support 7 on the angle fine-tuning device 4 to align the mining truck rotor disassembly fixture 5 with the mining truck rotor 12 to be disassembled / reassembled. Then, the operator drives the hydraulic motor 8 to control the rotation of the first drive gear 52 and the second driven gear, thereby controlling the disassembly screw 54 to be tightly connected with the mining truck rotor 12, completing the safe and efficient disassembly of the mining truck rotor 12.

[0036] When the mining truck needs to repair the mining truck brake caliper 13, the operator first uses the mining truck brake caliper disassembly tool 6 to disassemble the mining truck brake caliper 13. Then, the mining truck brake caliper tool 6 is removed, and the mining truck rotor disassembly tool 5 is installed. If the distance is close, the remote control handle can be used to operate to the destination. When the operator drives the replacement vehicle to the side of the mining truck brake caliper 13 to be disassembled, the operator uses the remote control to drive the vertical swing arm 2 and the horizontal telescopic arm 3 to reach the required disassembly and assembly height. Then, the operator remotely operates the slewing support 7 on the angle fine adjustment device 4 to align the brake caliper disassembly tool 6 with the mining truck brake caliper 13 to be disassembled and assembled. Then, the brake caliper clamp cylinder 65 is driven to control the brake caliper clamp 66 to clamp the mining truck brake caliper 13. Finally, the screw remover 64 is activated to remove the screws fixing the mining truck brake caliper 13, completing the safe and efficient disassembly of the mining truck brake caliper 13.

[0037] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution of this utility model, shall fall within the protection scope of this utility model.
