Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of ship loader equipment, and more specifically, to a quick-change structure for the traveling wheel assembly of a ship loader. Background Technology
[0002] Ship loaders are large bulk material handling machines used for loading bulk materials onto ships at bulk terminals. Generally, a ship loader consists of a boom conveyor belt, transition conveyor belt, telescopic chute, tail car, traveling device, gantry, tower, pitching device, and slewing device.
[0003] Existing ship loaders and other similar equipment use rail-mounted trolleys that cannot detach from the rails and cannot turn independently.
[0004] A search revealed that Chinese patent CN216945381U discloses a ship loader's traveling wheel assembly. By setting traveling wheels, which are installed on sleeves, and the sleeves are installed on support seats, and the support seats are rotatably installed on the ship loader around their own central axis, the traveling wheels can be rotated in all directions, allowing the ship loader to move independently of the guide rails, thus improving the convenience of the ship loader's movement.
[0005] In actual use, the installation process of the aforementioned ship loader's traveling wheel set is quite complicated, requiring the tightening of multiple bolts. The operation is cumbersome and time-consuming, and requires a lot of installation tools for installation and disassembly, which will cause the ship loader to be shut down for a long time.

[0011] As a further description of the above technical solution: the support mechanism includes a dual-axis motor, with lead screws fixedly connected to both output ends of the dual-axis motor.

[0026] The disassembly assembly includes two drive motors 5, each fixedly connected to one side of a connecting bracket 3. A turntable 6 is fixedly connected to the output end of each drive motor 5. A coupling 8 is fixedly connected to the front of the turntable 6, and three threaded sleeves 9 are fixedly connected to the front of the turntable 6. A hexagonal ferrule 15 is fixedly connected to the inner side of the traveling wheel 4, and the inner side of the hexagonal ferrule 15 is adapted to the outer side of the coupling 8. A fixed plate 10 is fixedly connected inside the traveling wheel 4, and a first gear 11 is rotatably connected inside the fixed plate 10. A hexagonal nut 12 is fixedly connected to one end of the first gear 11, and the hexagonal nut 12 is rotatably connected to the inside of the fixed plate 10. Three threaded sleeves 9 mesh on the outer side of the first gear 11. Each second gear 13 has a threaded rod 14 fixedly connected to one end. The threaded rod 14 is rotatably connected to the inside of the fixed disc 10 and threadedly connected to the inside of the connecting threaded cylinder 9. By rotating the hexagonal nut 12, the hexagonal nut 12 engages and drives the three second gears 13 to rotate. The hexagonal sleeve 15 is adapted to the outside of the coupling 8, so that the coupling 8 can provide positioning for the installation of the traveling wheel 4. The hexagonal nut 12 can drive the three threaded rods 14 to separate and connect with the connecting threaded cylinder 9, which simplifies the installation and disassembly process of the traveling wheel 4, so that the traveling wheel 4 can be replaced quickly.
[0027] Reference Figure 2 and 3 As shown, the support mechanism includes a dual-axis motor 16, with lead screws 17 fixedly connected to both output ends of the dual-axis motor 16. The lead screws 17 are rotatably connected to the inside of the outer shell 2. A movable bracket 18 is threadedly connected to the outside of the lead screws 17, and the movable bracket 18 is slidably connected to the inside of the outer shell 2.

A support base 22 is fixedly connected to the bottom end of the hydraulic rods 21. By utilizing the symmetrical distribution of the two lead screws 17, both lead screws 17 can drive the movable bracket 18 to move through the threads, so that the movable bracket 18 can drive the two hydraulic rods 21 to extend outward of the outer shell 2 through the connecting plate 20.

[0028] Working principle of this utility model: This utility model designs a quick-change structure for the traveling wheel set of a ship loader, the specific structure of which is shown in the attached instruction manual. Figure 1-7As shown, in this technical solution, through the cooperation between various structures, when it is necessary to disassemble and replace one of the walking wheels 4, the dual-axis motor 16 is first started. The dual-axis motor 16 simultaneously drives two lead screws 17 to rotate. Through the opposite helical directions of the two lead screws 17, both lead screws 17 can drive the movable bracket 18 to move to one side through the threads. The two guide rods 19 can provide guidance for the movement of the movable bracket 18, so that the two movable brackets 18 can drive the two hydraulic rods 21 to extend outward through the connecting plate 20. Then, multiple hydraulic rods 21 are activated. Supported by multiple hydraulic rods 21, multiple traveling wheels 4 can be separated from the ground. Then, the worker only needs a tool that can be matched with the outside of the hexagonal nut 12 and rotates the hexagonal nut 12. The hexagonal nut 12 can drive the first gear 11 to rotate. The second gear 13 meshes with the three first gears 11, so that the three second gears 13 can drive the threaded rod 14 inside the turntable 6. While rotating the hexagonal nut 12, the traveling wheels 4 are pulled outward, thereby separating the three threaded rods 14 from the connecting threaded cylinder 9, thus completing the disassembly of the traveling wheels 4.
[0029] When it is necessary to install the traveling wheel 4, first connect the hexagonal ferrule 15 on the inner side of the traveling wheel 4 to the coupling 8. The inner side of the hexagonal ferrule 15 is compatible with the coupling 8. The coupling 8 can provide positioning when installing the traveling wheel 4. Then, while rotating the hexagonal nut 12, push the traveling wheel 4 so that it can be threadedly connected to the inner side of the connecting threaded cylinder 9, thereby completing the installation of the traveling wheel 4.
