[0018] This embodiment provides a cleaning device for valve balls, including a body 1, a hanging rod 2, a hook 3 fixed to the bottom of the hanging rod 2, and a drive mechanism 4 for driving the displacement of the hanging rod 2, and further including: A transverse support 5 is provided at the bottom of the hanging rod 2, and the transverse support 5 has an assembly hole 6. A threaded connecting sleeve 7 is provided in the assembly hole 6, and the threaded connecting sleeve 7 is threadedly connected to the upper part of the hook 3. A limiting flange 8 is provided on the top of the threaded connecting sleeve 7, and a pressure-bearing gasket 9 is provided between the limiting flange 8 and the transverse support seat 5. A locking cover plate 10 is provided above the threaded connecting sleeve 7, and a circumferential anti-rotation structure is provided between the locking cover plate 10 and the hook 3; The locking cover plate 10 is fixedly connected to the transverse support 5 by the clamping bolt 11, and the locking cover plate 10 is also fixedly connected to the hook 3 by the anti-loosening bolt 12.

[0019] A cleaning device for valve balls comprises a body 1, a conveying assembly, a cleaning tank, a hanging rod 2, a hook 3, and a drive mechanism 4. The body 1 serves as the support carrier for the device. The cleaning tank is arranged sequentially along the conveying direction of the device for cleaning the valve balls. The drive mechanism 4 consists of a power assembly, a transmission chain, sprockets, and guide rails. The sprockets are rotatably connected to the body 1, and the transmission chain meshes with each sprocket. The guide rails are fixed to the body 1 and arranged along the conveying direction. The hanging rod 2 is fixedly connected to the transmission chain via clamping components. The power assembly drives the sprockets to rotate, and the sprockets, through meshing, drive the transmission chain to move along the extension direction of the guide rails, thereby causing the hanging rod 2 to complete continuous displacement along a preset path.

[0020] The hanging rod 2 extends vertically, and the hooks 3 are arranged below the hanging rod 2 to cooperate with the support basket containing the valve ball and to lift it. Each support basket is supported by at least four hooks 3 to keep the support basket horizontal and stable during movement. The bottom of the hanging rod 2 is integrally formed with a horizontal support seat 5. The extension direction of the horizontal support seat 5 is perpendicular to the vertical extension direction of the hanging rod 2. The horizontal support seat 5 has a vertically penetrating mounting hole 6 inside. The threaded connecting sleeve 7 is arranged inside the assembly hole 6 of the transverse support 5. The outer contour of the threaded connecting sleeve 7 is adapted to the inner wall contour of the assembly hole 6. The top of the threaded connecting sleeve 7 is integrally provided with a limiting flange 8, which extends outward along the radial direction of the threaded connecting sleeve 7. A pressure bearing pad 9 is arranged between the limiting flange 8 and the upper end face of the transverse support 5. The upper end face of the pressure bearing pad 9 is in contact with the lower end face of the limiting flange 8, and the lower end face of the pressure bearing pad 9 is in contact with the upper end face of the transverse support 5. The threaded connecting sleeve 7 achieves axial limiting and pressing in the assembly hole 6 through the contact and cooperation of the limiting flange 8 and the pressure bearing pad 9.

[0021] The upper part of the hook 3 has a connecting stud 15. The outer wall of the connecting stud 15 is provided with external threads, and the inner wall of the threaded connecting sleeve 7 is provided with internal threads. The connecting stud 15 extends into the threaded connecting sleeve 7 and forms a threaded connection with the threaded connecting sleeve 7, so that the hook 3 and the threaded connecting sleeve 7 form a detachable assembly relationship. A locking cover plate 10 is arranged above the threaded connecting sleeve 7. The locking cover plate 10 covers the top of the threaded connecting sleeve 7 and the limiting flange 8. A circumferential anti-rotation structure is provided between the locking cover plate 10 and the hook 3. The circumferential anti-rotation structure includes an anti-rotation boss 13 integrally provided on the inner side of the locking cover plate 10 and an anti-rotation groove 14 correspondingly opened on the top of the hook 3. The anti-rotation boss 13 adopts a regular polygonal columnar structure, and all circumferential sides are flat. The inner wall of the anti-rotation groove 14 fits against the outer wall of the anti-rotation boss 13. The relative rotation between the hook 3 and the locking cover plate 10 is restricted by the planar fit. The anti-rotation boss 13 is embedded in the anti-rotation groove 14, so that the hook 3 and the locking cover plate 10 cannot rotate circumferentially.

[0022] A clamping bolt 11 is fitted on the locking cover plate 10. The clamping bolt 11 passes vertically from top to bottom through the locking cover plate 10, the threaded connecting sleeve 7, and the pressure washer 9, and finally forms a threaded connection with the pre-set threaded hole on the transverse support 5, thus axially clamping the locking cover plate 10, the threaded connecting sleeve 7, the pressure washer 9, and the transverse support 5 into a single unit. The locking cover plate 10 is also fitted with an anti-loosening bolt 12. The anti-loosening bolt 12 passes vertically from top to bottom through the locking cover plate 10, and finally forms a threaded connection with the pre-set threaded hole at the top of the hook 3, so that the locking cover plate 10 and the hook 3 directly form a locking fit.

[0023] During equipment operation, the drive mechanism 4 drives the hanging rod 2 to move along the conveying direction via the transmission chain. The hanging rod 2 drives the threaded connecting sleeve 7 and the hook 3 to move synchronously via the transverse support seat 5. The hook 3 lifts the carrying basket and passes through the cleaning tank to complete the cleaning process. The threaded connecting sleeve 7 and the hook 3 are connected by threads, which can be disassembled and replaced separately. The limiting flange 8 cooperates with the pressure bearing gasket 9 to limit the axial movement of the threaded connecting sleeve 7. The anti-rotation boss 13 cooperates with the anti-rotation groove 14 to limit the circumferential rotation of the hook 3. The clamping bolt 11 clamps and fixes the overall structure, and the anti-loosening bolt 12 further locks the locking cover plate 10 and the hook 3, so that the overall connection structure remains stable during equipment operation and does not loosen, rotate or fall off.

[0024] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
