Therefore, we propose a portable unloading device for the reducer of a ship lift. Utility Model Content

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0025] Many specific details are set forth in the following description in order to provide a full understanding of this utility model. However, this utility model may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.
[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of this utility model. The phrase "in an embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.
[0027] Secondly, this utility model is described in detail with reference to the schematic diagrams. When detailing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.
[0028] Example 1, referring to Figures 1 to 3 A portable ship lift reducer unloading device is provided, including a base plate 100, a support frame 200 fixedly connected to the side of the base plate 100, and an adjustment mechanism 300 provided on the top of the base plate 100.
[0029] The adjustment mechanism 300 includes a motor 301, the bottom of which is fixedly connected to the top of the base plate 100. The output shaft of the motor 301 is fixedly connected to a threaded rod 302. A threaded sleeve 303 is threadedly connected to the circumferential surface of the threaded rod 302. A connecting rod 304 is fixedly connected to the side of the threaded sleeve 303. A jack 305 is fixedly connected to the end of the connecting rod 304 away from the side of the threaded sleeve 303. A moving rod 306 is fixedly connected to the bottom of the jack 305. A moving groove 307 is opened on the top of the base plate 100. The side of the moving rod 306 is slidably connected to the inside of the moving groove 307. A connecting plate 308 is fixedly connected to the top cover of the jack 305.
[0030] The side of the connecting plate 308 is threaded with a fixing bolt 309. The circumferential surface of the threaded rod 302 is fixedly penetrated by the limiting plate 310. The function of the fixing bolt 309 on the side of the connecting plate 308 is to connect the jack 305 to the reducer through the fixing bolt 309 and the connecting plate 308. The function of the limiting plate 310 is to limit the displacement distance of the threaded sleeve 303 through the limiting plate 310.
[0031] A limiting shaft 311 is fixedly connected to the side of the motor 301. The circumferential surface of the limiting shaft 311 penetrates the side of the threaded sleeve 303 and is slidably connected to the side of the threaded sleeve 303. The function of the limiting shaft 311 in penetrating the side of the threaded sleeve 303 and being slidably connected to the side of the threaded sleeve 303 is to prevent the threaded sleeve 303 from rotating during movement.
[0032] The number of fixing bolts 309 is set to two, and they are arranged in a linear array along the side of the connecting plate 308. The purpose of setting the number of fixing bolts 309 to two and arranging them in a linear array along the side of the connecting plate 308 is to make the connection more stable by using two fixing bolts 309, and to prevent the connection from breaking during operation.
[0033] Example 2, refer to Figures 2 to 4 This embodiment differs from the first embodiment in that: a support mechanism 400 is provided on the top of the base plate 100. The support mechanism 400 includes a rotating shaft 401, one end of which is fixedly connected to the end of the threaded rod 302 away from the output shaft of the motor 301. A gear 402 is fixedly passed through the circumferential surface of the rotating shaft 401. A sliding groove 403 is provided on the top of the base plate 100. A sliding column 404 is slidably connected inside the sliding groove 403. A rack is fixedly connected to the end of the sliding column 404 away from the inside of the sliding groove 403. 405, a support rod 406 is fixedly connected to the top of the rack 405, an extension plate 407 is fixedly connected to the top of the support rod 406, a telescopic column 408 is fixedly connected to the top of the base plate 100, a fixed support plate 409 is fixedly connected to the telescopic end of the telescopic column 408, the bottom of the extension plate 407 is slidably connected to the top of the fixed support plate 409, and the support mechanism 400 is provided on the top of the base plate 100 to provide more effective support for reducers of different weights and sizes.
[0034] The rest of the structure is the same as in Example 1.
[0035] Example 3, referring to Figures 2 to 4 The difference between this embodiment and the above embodiment is that the piston rod of the jack 305 is fixedly connected to a telescopic rod 410, and the telescopic end of the telescopic rod 410 is fixedly connected to the telescopic end of the telescopic column 408. The function of the fixed connection between the telescopic end of the telescopic rod 410 and the telescopic end of the telescopic column 408 is to enable the telescopic column 408 to move by moving the jack 305.
[0036] The circumferential surface of gear 402 meshes with the side surface of rack 405. The purpose of this meshing is to ensure that when gear 402 rotates, it can drive rack 405 to move.
[0037] A specific application of this embodiment is as follows: When the reducer needs to be unloaded, the worker starts the motor 301 according to the force on the center of gravity of the reducer. The output shaft of the motor 301 rotates counterclockwise, which drives the threaded rod 302 to rotate counterclockwise. The threaded sleeve 303, which is threaded to the circumferential surface of the threaded rod 302, moves along the X-axis. The movement of the threaded sleeve 303 along the X-axis is transmitted through the connecting rod 304, which in turn drives the jack 305 to move along the X-axis through the moving rod 306 inside the moving groove 307. At this time, the worker adjusts the position of the jack 305 appropriately according to the size of the reducer. After the adjustment is completed, the jack 305 is connected to the reducer through the connecting plate 308 and the fixing bolt 309.
[0038] To prevent uneven force distribution and tilting of the reducer, the operator can start motor 301. The output shaft of motor 301 will rotate counterclockwise, causing the threaded rod 302 to rotate counterclockwise. The rotating shaft 401, fixed to one end of the threaded rod 302, will also rotate counterclockwise, driving the gear 402 to rotate counterclockwise. Because gear 402 meshes with rack 405, the counterclockwise rotation of gear 402... The rack 405 moves along the Y-axis inside the slide groove 403 via the sliding column 404. The movement of the rack 405 along the Y-axis drives the extension plate 407 to move along the Y-axis via the support rod 406. When the extension plate 407 moves along the Y-axis, it increases the contact area between the fixed support plate 409 and the reducer. When the jack 305 extends or retracts, the fixed support plate 409 moves with the jack 305 via the extension rod 410 and the extension column 408, maintaining contact with the reducer.
[0039] The rest of the structure is the same as in Example 2.
