Technical Field

[0001] This utility model relates to the technical field of motor small gear disassembly equipment, and in particular to a disassembly tooling for the traveling motor gear of a stacker-reclaimer. Background Technology

[0002] Disassembling the travel motor gears is a common and important task in the daily maintenance and repair of stacker-reclaimers. The output pinions of the travel motors in stacker-reclaimers are usually made using a special process. The advantages of this process are modularity, tight meshing, and hardness. However, it also has certain disadvantages. The tight meshing makes disassembly difficult, requires specialized equipment, and improper force direction during disassembly can easily damage the motor shaft. Traditional disassembly methods may involve forcibly disassembling the travel motor gears and related components, which can easily damage equipment parts and even affect the overall performance of the equipment. Utility Model Content

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a disassembly fixture for the traveling motor gear of a stacker-reclaimer, wherein a traveling motor gear is connected to the motor shaft of the traveling motor, including a fixing clamping device and a hydraulic device. The fixing clamping device is a square frame made of steel plate, and a semi-circular groove is formed on the bottom plate of the square frame. The motor shaft of the traveling motor passes through the semi-circular groove, and the center of the semi-circular groove is located at the center of the bottom plate of the square frame. The inner plane of the bottom plate of the square frame is flush with the bottom surface of the traveling motor gear. The hydraulic device is a hydraulic jack, and the base plane of the hydraulic jack is flush with the inner plane of the top plate of the square frame. The piston rod axis of the hydraulic jack is kept on the same line as the motor shaft axis of the traveling motor, and the piston rod of the hydraulic jack is connected to the motor shaft of the traveling motor.

[0005] Furthermore, a pad is provided between the hydraulic jack and the inner plane of the square frame top plate.

[0006] Furthermore, a shoulder plate is fixedly installed on the outer plane of the top surface of the square frame.

[0007] Furthermore, the handle of the hydraulic jack faces outward from the square frame.

[0008] The beneficial effects of this utility model are: the design of this utility model takes into account the structural characteristics and disassembly requirements of different walking motor shaft extension dimensions, ensuring that relevant components can be accurately aligned and fixed during disassembly, avoiding damage or decrease in precision caused by improper disassembly; it realizes the entire process from gear positioning to jack fixing and disassembly, which helps to maintain the integrity of the walking motor during disassembly, reduces quality loss caused by disassembly, and thus improves the overall quality of the product.

[0014] The following will describe in detail the embodiments of this utility model with reference to the accompanying drawings. Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0016] like Figures 1-3 As shown, a disassembly fixture for the traveling motor gear of a stacker-reclaimer is disclosed. The traveling motor 1 has a traveling motor gear 2 connected to its motor shaft. The fixture comprises a fixing and clamping device and a hydraulic device. The fixing and clamping device is a square frame 3 made of steel plate. A semi-circular groove 4 is formed on the bottom plate of the square frame 3. The motor shaft of the traveling motor 1 passes through the semi-circular groove 4, and the center of the semi-circular groove 4 is located at the center of the bottom plate of the square frame 3. The inner plane of the bottom plate of the square frame 3 is flush with the bottom surface of the traveling motor gear 2. The hydraulic device is a hydraulic jack 5. The base plane of the hydraulic jack 5 is flush with the inner plane of the top plate of the square frame 3. The piston rod axis of the hydraulic jack 5 is aligned with the motor shaft axis of the traveling motor 1. The piston rod of the hydraulic jack 5 is connected to the motor shaft of the traveling motor 1. The hydraulic jack 5 applies external force to the fixing and clamping device, thereby disassembling the traveling motor gear 2.

[0017] A pad 6 is provided between the hydraulic jack 5 and the inner plane of the top plate of the square frame 3. If the clearance between the piston rod of the hydraulic jack 5 and the motor shaft of the traveling motor 1 is too large, it can be adjusted by adding an appropriate pad 6 between the base of the hydraulic jack 5 and the top plate of the fixing clamping device.

[0018] A shoulder plate 7 is fixedly installed on the outer surface of the top of the square frame 3. This facilitates the movement and fixing of the clamping device.

[0019] The handle of the hydraulic jack 5 faces outward from the square frame 3. Sufficient operating space is provided for the hydraulic jack 5 to ensure convenient operation.

[0020] The method and principle of this utility model are as follows: First, the walking motor 1 and the walking motor gear 2 are fixed by the fixing and clamping device. At the same time, the hydraulic device is placed between the fixing and clamping device and the walking motor gear 2. The fixing and clamping device is driven by the hydraulic device to move away from the walking motor 1, and the walking motor gear 2 is removed from the motor shaft, thus completing the quick disassembly of the walking motor gear 2. The disassembly is convenient, time-saving and labor-saving.

[0021] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any improvements made using the inventive concept and technical solution of the present invention, or direct application to other situations without modification, are all within the protection scope of the present invention.
