This patent has the advantages of simple structure, low cost, convenient unloading, and high working efficiency, but it still has the following drawbacks:
[0004] (1) Existing devices lack displacement capabilities, making it difficult for them to handle unloading operations of different scales.
[0005] (2) Due to the special lifting operation of the unloading device, the components are prone to loosening during the support process. To address this, a movable plastic roll unloading device is proposed. Utility Model Content
[0006] The purpose of this invention is to address the problem that existing devices lack displacement capabilities, making it difficult for them to handle unloading operations of varying scales.
[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution:
[0008] The present invention is as follows: a movable plastic roll unloading device includes a support frame body, a lifting assembly is provided on the top of the support frame body, a displacement fixing device is provided on the bottom of the support frame body, the displacement fixing device includes a support column, the top of the support column is fixedly connected to the bottom of the support frame body, a flat base is fixedly connected to the bottom of the support column, a caster wheel is provided on the bottom of the flat base, a drive assembly is provided on the side of the support column, and a support leg is fixedly connected to the drive end of the drive assembly.
[0009] As a preferred technical solution of this utility model, the driving component includes a motor support plate, the side of which is fixedly connected to the side of the support column, a driving motor is fixedly connected to the top of the motor support plate, a threaded shaft is fixedly connected to the output shaft of the driving motor, a threaded sliding plate is threadedly connected to the threaded surface of the threaded shaft, a bottom support leg is fixedly connected to the bottom of the threaded sliding plate, a limiting sliding column is fixedly connected to the side of the support column, and the threaded sliding plate is provided as the driving end of the driving component.
[0010] As a preferred technical solution of this utility model, the lifting assembly includes a horizontal slide block, the bottom of which is fixedly connected to the top of the support frame body. A sliding plate is slidably connected to the bottom of the horizontal slide block, and an electric hoist is fixedly connected to the bottom of the sliding plate. A lifting link is provided at the bottom of the electric hoist.
[0011] As a preferred technical solution of this utility model, the outer wall of the limiting slide column is in contact with the inner wall of the threaded slide groove, and the outer wall of the bottom support leg is in contact with the inner wall of the groove of the flat bottom plate.
[0012] As a preferred technical solution of this utility model, the bottom of the support leg is cone-shaped and the bottom of the support leg is made of a highly anti-slip material.
[0013] As a preferred technical solution of this utility model, a locking device is provided on the side of the threaded slide plate. The locking device includes an elastic telescopic rod. The fixed end of the elastic telescopic rod is fixedly connected to the side of the threaded slide plate. The telescopic end of the elastic telescopic rod is fixedly connected to a translation plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] 1. Through the set displacement fixing device, the support column, flat bottom plate, casters, motor support plate, drive motor, threaded shaft, threaded slide plate, bottom support leg, and limiting slide column are coordinated. At this time, the bottom support leg and the main body of the support frame form a mutual reaction force, which makes the bottom support leg lift the main body of the support frame, thereby making the casters detach from the ground. The setting of displacement components improves the position adaptability of the device, enabling the device to cope with unloading operations of different scales.
[0017] 2. The locking device allows the elastic telescopic rod, the sliding plate, and the limiting plate to work together. After the limiting plate is no longer subjected to the force of the flat base, it is moved towards the threaded slide plate by the elastic force of the elastic telescopic rod. This causes the top surface of the limiting plate to be fastened to the ground of the flat base, further restricting the position of the support legs and thus preventing the components from becoming loose during the support process.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
[0026] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.
[0027] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, this embodiment proposes a movable plastic roll unloading device, including a support frame body 1. A lifting assembly 2 is provided at the top of the support frame body 1, and a displacement fixing device 3 is provided at the bottom of the support frame body 1. The displacement fixing device 3 includes a support column 31, the top of which is fixedly connected to the bottom of the support frame body 1. A flat base plate 32 is fixedly connected to the bottom of the support column 31, and casters 33 are provided at the bottom of the flat base plate 32. A drive assembly is provided on the side of the support column 31, and a support leg 38 is fixedly connected to the drive end of the drive assembly. The drive assembly includes a motor support plate 34, the side of which is fixedly connected to the side of the support column 31. A drive motor 35 is fixedly connected to the top of the motor support plate 34, and a threaded shaft 36 is fixedly connected to the output shaft of the drive motor 35. The threaded surface of the threaded shaft 36... The upper threaded plate 37 is connected to the threaded plate 37, and the bottom of the threaded plate 37 is fixedly connected to the bottom support leg 38. The side of the support column 31 is fixedly connected to the limiting slide column 39. The threaded plate 37 is set as the driving end of the drive assembly. The lifting assembly 2 includes a cross rail slide 21. The bottom of the cross rail slide 21 is fixedly connected to the top of the support frame body 1. The bottom of the cross rail slide 21 is slidably connected to a sliding plate 22. The bottom of the sliding plate 22 is fixedly connected to an electric hoist 23. The bottom of the electric hoist 23 is provided with a lifting connecting rod 24. The outer wall of the limiting slide column 39 is in contact with the inner wall of the slide groove of the threaded plate 37. The outer wall of the bottom support leg 38 is in contact with the inner wall of the groove of the flat bottom plate 32. The bottom of the bottom support leg 38 is set in a conical shape. The bottom of the bottom support leg 38 is set with a high anti-slip material. The drive motor 35 is electrically connected to an external controller.
[0029] According to the above structure, the worker fixes the roll material to be lifted onto the lifting link 24. Then, the worker starts the electric hoist 23 through the external controller, so that the electric hoist 23 lifts the roll material. Before starting the lifting work, the worker moves the support frame body 1 to the designated position through the casters 33. Then, the worker starts the drive motor 35 through the external controller. The output shaft of the drive motor 35 rotates, which drives the threaded shaft 36 to rotate. The rotation of the threaded shaft 36 causes the threaded slide plate 37 to move downward under the restriction of the limiting slide column 39. The downward threaded movement of the threaded slide plate 37 drives the bottom support leg 38 to move downward. When the bottom support leg 38 moves downward and contacts the ground, the bottom support leg 38 continues to move downward. At this time, the bottom support leg 38 and the support frame body 1 form a mutual reaction force, which makes the bottom support leg 38 lift the support frame body 1, thereby causing the casters 33 to detach from the ground. By setting the displacement component, the position adaptability of the device is improved, so that the device can cope with unloading operations of different scales.
[0030] like Figure 5 As shown, in a preferred embodiment, based on the above method, a locking device 4 is further provided on the side of the threaded slide plate 37. The locking device 4 includes an elastic telescopic rod 41. The fixed end of the elastic telescopic rod 41 is fixedly connected to the side of the threaded slide plate 37, and the telescopic end of the elastic telescopic rod 41 is fixedly connected to a translation plate 42. A limiting plate 43 is fixedly connected to the side of the translation plate 42 near the elastic telescopic rod 41. The bottom of the limiting plate 43 is set with an incline, and the top of the flat plate 32 is located on the movement trajectory of the limiting plate 43. The incline setting can ensure smoother operation of the component.
[0031] According to the above structure, the downward movement of the threaded slide plate 37 drives the elastic telescopic rod 41 to move downward. The downward movement of the elastic telescopic rod 41 drives the translation plate 42 to move downward. The downward movement of the translation plate 42 drives the limiting plate 43 to move downward. The limiting plate 43 moves downward so that its inclined surface contacts the top surface of the flat base plate 32. At this time, the inclined surface of the limiting plate 43 moves downward and away from the threaded slide plate 37 after being subjected to the reverse force of the flat base plate 32. After the limiting plate 43 moves and passes the flat base plate 32, the limiting plate 43 is no longer subjected to the force of the flat base plate 32, but is subjected to the elastic force of the elastic telescopic rod 41 and moves towards the threaded slide plate 37. This makes the top surface of the limiting plate 43 and the ground of the flat base plate 32 interlock, further restricting the position of the support leg 38, thereby preventing the components from becoming loose during the support process.
[0032] All technical features in this embodiment can be freely combined according to actual needs.
[0033] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
