Description

Technical Field

[0001] This utility model relates to the field of hydraulic devices, specifically to a hydraulic device for disassembling wheel axles. Background Technology

[0002] Bucket wheel reclaimers are key equipment in material reclaiming operations. The main function of the traveling wheels of a bucket wheel reclaimer is to support the entire machine and enable it to move. The traveling wheel device is a vulnerable part of the bucket wheel reclaimer, requiring frequent maintenance and replacement, and is difficult and inefficient to maintain.

[0003] Currently, the main method for disassembling wheel axles is to manually strike the axle with a hammer to separate it from the wheels. This method is laborious and poses significant safety hazards. If the hammer is not held firmly, it can easily injure the worker. If the wheel axle is deformed, it is very difficult to disassemble it manually. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and propose a hydraulic device for disassembling wheel axles. This device can use hydraulic driving force to disassemble the wheel axles of walking wheels. It has a compact overall structure, is easy to use, can reduce labor intensity, improve work efficiency, and effectively ensure the safety of workers.

[0005] To achieve the above objectives, the present invention proposes the following technical solution:

[0006] A hydraulic device for disassembling a wheel axle includes a main frame, a hydraulic cylinder, pads, and a pad fixing device. The main frame has a base at its bottom for fixing its position. An open space is provided on the main frame, and the hydraulic cylinder is located within this open space. A wheel axle disassembly hole is provided on one side of the open space for placing the wheel axle. Two pads are provided within the open space, positioned opposite each other, with one side of each pad abutting against the side of the open space with the wheel axle disassembly hole. The pads serve to limit the movement of the wheel. The pad fixing device, used for limiting the pads, includes a screw, a limiting block, and a bolt. The screw is threadedly connected to the main frame, and the limiting block is located on the screw. The limiting block has a through hole, and the bolt passes through the through hole in the limiting block and is threadedly connected to the pad.

[0007] Preferably, the supporting surface of the pad is an arc surface or an inclined surface.

[0008] Preferably, the bottom side of the open space is provided with a sliding groove, and the bottom surface of the pad is provided with a slider that cooperates with the sliding groove, so that the pad is slidably connected to the main frame, which facilitates the installation and disassembly of the pad, and facilitates the placement and disassembly of the walking wheel device.

[0009] Preferably, the hydraulic cylinder is installed in the open space of the main frame via a lifting device, which can be a hydraulic device or a jack.

[0010] Preferably, the bottom of the main base is provided with multiple omnidirectional brake wheels to facilitate the movement and handling of the entire device, and is provided with four hydraulic lifting outriggers for stable support during operation.

[0011] Specifically, the pad is first placed in an open space, then the traveling wheel with axle is placed on the pad, and the axle passes through the axle removal hole. The screw is screwed into the main frame until the limiting block abuts against the pad. Then the bolt passes through the limiting hole and is threadedly connected to the pad, thereby limiting the position of the pad.

[0012] Adjust the height of the hydraulic cylinder so that the hydraulic shaft of the hydraulic cylinder is aligned with the wheel axle. Then start the hydraulic shaft to apply pressure to the wheel axle until the wheel axle disengages from the traveling wheel. After that, the hydraulic cylinder returns to its original position, and the disassembled traveling wheel and wheel axle can be removed from the main frame.

[0013] The beneficial effects of this utility model are as follows:

[0014] This utility model features an open space within the main frame, a hydraulic cylinder housed within the open space, and pads used to limit the movement of the wheels. It utilizes hydraulic driving force to disassemble the wheel axles, resulting in a compact overall structure that is easy to use, reduces labor intensity, improves work efficiency, and effectively ensures worker safety.

[0015] This invention uses a pad fixing device to limit the pad's position, further enhancing the stability of the device.

[0016] By adopting the above solution, this utility model can disassemble the axle of the walking wheel using hydraulic driving force. The overall structure is compact, easy to use, can reduce labor intensity, improve work efficiency, and effectively ensure the safety of workers. Attached Figure Description
