Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, and in particular to an automatic protective sleeve loading and unloading device. Background Technology

[0002] A wheelset turning protective sleeve is a specialized protective device installed on the journals and bearings of a wheelset. It is primarily used to protect the precision journals and bearing surfaces from damage during wheelset transportation, storage, and processing. Its core functions are threefold: first, to prevent impacts, scratches, or corrosion to the journals; second, to prevent metal shavings, cutting fluid, and other contaminants from entering the bearing sealing area; and third, to protect the bearing from external impacts. During wheelset turning, the machining of the rim and tread generates a large amount of metal shavings and cutting fluid. If the protective sleeve is not removed, these impurities may seep into the bearing, affecting its lifespan. Furthermore, the protective sleeve itself can hinder measurement and operation of the machining area. Therefore, it must be removed before turning and reinstalled after machining is completed and the area is thoroughly cleaned to ensure the integrity of critical wheelset components and safe operation.

[0003] Traditional protective sleeve removal devices use simple tools for disassembly, which not only increases the time and labor costs of disassembly and reduces operational efficiency, but also lacks standardized force control, which can easily cause deformation of the protective sleeve groove or scratches on the journal surface. These damages may lead to subsequent bearing seal failure, ultimately shortening the bearing's service life and increasing later maintenance costs.

[0004] Therefore, in view of the problems of low operating efficiency, insufficient disassembly precision control, and increased maintenance costs caused by the use of simple tools for disassembly of the aforementioned traditional protective sleeve disassembly devices, an automatic protective sleeve loading and unloading device can be designed to solve the above problems.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-5 This utility model provides an embodiment: an automatic protective sleeve loading and unloading device, including a frame 1; and a conveying assembly. The conveying assembly is fixedly connected to the top of the frame 1, a sliding plate 3 is connected to the conveying assembly, a hydraulic cylinder 4 is fixedly connected to the sliding plate 3, a hydraulic rod 5 is fixedly connected to the output end of the hydraulic cylinder 4, a sliding connecting rod 7 is fixedly connected to the hydraulic rod 5, a limit plate 6 is fixedly connected to the sliding plate 3, the sliding connecting rod 7 is slidably connected to the limit plate 6, a double-ended connecting key 8 is rotatably connected to both ends of the sliding connecting rod 7, a rotating clamping plate 9 is rotatably connected to the double-ended connecting key 8, and a second... A connecting shaft 10 is fixedly connected to a limiting plate 6. The front and rear wheels of the turning machine are installed on the lathe. The machine frame 1 is aligned with the front and rear wheels of the turning machine. Power is output by the conveying component to drive the sliding plate 3 to move linearly and approach the protective sleeve. Then, the hydraulic cylinder 4 outputs pressure to the hydraulic rod 5, pushing the hydraulic rod 5 to move linearly. The hydraulic rod 5 pushes the sliding connecting rod 7 to slide on the limiting plate 6, causing the double-headed connecting key 8 to rotate and move forward at the same time. This drives the rotating clamp 9 to rotate on the first connecting shaft 10. The rotating clamp 9 is used to clamp and remove the protective sleeve on the front and rear wheels of the turning machine.

[0024] Please see Figures 2-4In this embodiment, the conveying assembly includes a sliding guide rail 201, a threaded rod 202, and a first drive motor 203. The sliding guide rail 201 is fixedly connected to the frame 1, and the first drive motor 203 is fixedly connected to the sliding guide rail 201. The output end of the first drive motor 203 is fixedly connected to the threaded rod 202, and the threaded rod 202 is rotatably connected to the sliding guide rail 201. The first drive motor 203 outputs torque to rotate the threaded rod 202, thereby driving the sliding plate 3, which is threadedly connected to the threaded rod 202, to move linearly along the sliding guide rail 201. The machine is in motion. A second drive motor 11 is fixedly connected to the frame 1. A drive shaft 12 is fixedly connected to the output end of the second drive motor 11. The second drive motor 11 is fixed to the frame 1. The torque output of the second drive motor 11 is given to the drive shaft 12, causing the drive shaft 12 to rotate. A second connecting shaft 15 is rotatably connected to the frame 1. A driven roller 14 is fixedly connected to the outside of the second connecting shaft 15. The second connecting shaft 15 is mounted on the frame 1. The driven roller 14 is used for transmission, driving the second connecting shaft 15 to rotate together.

[0025] Please see Figures 1-3 In this embodiment, a transmission belt 13 is sleeved on the outer side of the driven roller 14 and the drive shaft 12. A rotating plate 16 is provided on one side of the frame 1. When the drive shaft 12 rotates, it drives the transmission belt 13 sleeved on the outer side to move together, thereby driving the driven roller 14 to rotate. The rotating plate 16 is fixedly connected to the second connecting shaft 15. Several guide rods 17 are fixedly connected to the rotating plate 16. When the second connecting shaft 15 rotates, it drives the rotating plate 16 to rotate, which can realize the disassembly of protective sleeves of different sizes. At the same time, the guide rods 17 are used to position the protective sleeves. Several clamping windows 1601 are provided on the rotating plate 16. The working direction of the rotating clamping plate 9 is facing the clamping window 1601. The rotating clamping plate 9 can directly contact the protective sleeve through the clamping window 1601 to complete the disassembly of the protective sleeve.

[0026] During operation, the front and rear turning wheels are mounted on the lathe, and the machine frame 1 is aligned with the turning wheels. Simultaneously, the protective sleeve is positioned using the guide rod 17. The second drive motor 11 outputs torque to the drive shaft 12, causing it to rotate. The drive shaft 12 drives the transmission belt 13 sleeved on the outside, which in turn drives the driven roller 14 to rotate. The driven roller 14 then drives the second connecting shaft 15 to rotate, which in turn drives the rotating plate 16 to rotate. This allows for the adaptation of protective sleeves of different sizes. The first drive motor 203 outputs torque to rotate the threaded rod 202, causing the sliding plate 3, which is threaded onto the threaded rod 202, to move linearly along the sliding guide rail 201. This causes the sliding plate 3 to approach the protective sleeve. Then, the hydraulic cylinder 4 outputs pressure to the hydraulic rod 5, pushing the hydraulic rod 5 to move linearly. This causes the hydraulic rod 5 to push the sliding connecting rod 7 to slide on the limit plate 6, causing the double-ended connecting key 8 to rotate and move forward. This causes the rotating clamp 9 to rotate on the first connecting shaft 10, and the rotating clamp 9 is used to clamp and remove the protective sleeves from the front and rear wheels of the turning machine.

[0027] Through the above steps, the rotating clamp 9, in conjunction with multiple driving components, enables automatic loading and unloading of the protective sleeve. The mechanical device quickly positions the protective sleeve, eliminating the need for frequent adjustments and significantly improving work efficiency and ensuring continuous operation. Simultaneously, the mechanical clamps precisely control the clamping force, preventing damage to the protective sleeve or other components, thus ensuring product quality, reducing subsequent maintenance costs and resource waste, and improving the device's economic benefits. This addresses the problems of traditional protective sleeve unloading devices that rely on simple tools for disassembly, resulting in low operational efficiency, insufficient disassembly precision control, and increased maintenance costs.
