[0022] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0023] Please see Figure 1-6 As shown, a lifting platform for pallet conveying includes a lifting platform body 1, with a lifting structure 2 inside the lifting platform body 1. A support platform 3 is fixedly connected between two lifting platform bodies 1. Several grooves 4 are formed on one side of the support platform 3. Universal joints 5 are installed inside the grooves 4. One end of the universal joint 5 is fixedly connected to the transmission structure inside the support platform 3, and the other end of the universal joint 5 is rotatably connected to a cross shaft 6. A second universal joint 7 is rotatably connected to the surface of the cross shaft 6, and the other end of the second universal joint 7 is fixedly connected to a roller 8. A protective sleeve 9 is provided on the surface. The protective sleeve 9 is made of wear-resistant rubber. This not only reduces the pressure of the pallet on the surface of the roller 8 and increases the service life of the roller 8, but also prevents the pallet from shaking above the support platform 3. A disc 10 is fixedly connected to the other end of the roller 8. A semi-circular block 11 is rotatably connected to the surface of the disc 10. The surface of the semi-circular block 11 is fixedly connected to the inside of the support platform 3. A flipping structure 12 is provided on the surface of the support platform 3. A limiting structure 13 for limiting the fixed plate 122 is provided inside the support platform 3.

[0024] The flipping structure 12 includes a rotating plate 121 hinged to the surface of the support platform 3. The surface of the rotating plate 121 is provided with several limiting grooves 123. Fixed plates 122 are fixedly connected to the front and rear sides of one side of the rotating plate 121. By setting the flipping structure 12, the disc 10 on one side of the roller 8 can be limited, so that the disc 10 can rotate between the semicircular block 11 and the limiting groove 123, ensuring that the roller 8 can operate normally.

[0025] The limiting structure 13 includes a rotating rod 131 rotatably connected inside the support platform 3. An adjusting knob 132 is fixedly connected to the surface of the rotating rod 131. The surface of the adjusting knob 132 is provided with several anti-slip textures, which facilitates easier and faster adjustment of the limiting plate 135. One end of the rotating rod 131 is fixedly connected to a threaded rod 133. A threaded sleeve 134 is threadedly connected to the surface of the threaded rod 133. A sliding groove is provided on the top of the support platform 3. The surface of the threaded sleeve 134 slides against the inner wall of the sliding groove, thereby increasing the stability of the threaded sleeve 134 during movement. The top of 134 is fixedly connected to a limiting plate 135. The top of the support platform 3 is provided with a guide groove 136. The inside of the guide groove 136 is slidably connected to the bottom of the limiting plate 135. Through the setting of the limiting structure 13, the adjustable knob 132 can be rotated to drive the rotating rod 131 and the threaded rod 133 to rotate, so that the threaded sleeve 134 moves on the surface of the threaded rod 133, which can drive the limiting plate 135 to slide along the guide groove 136, so that the top of the inner wall of the limiting plate 135 is in contact with the top of the fixed plate 122, thereby fixing the rotating plate 121.

[0026] Working Principle: After prolonged use of the pallet lift, the rollers 8 at the top of the platform 3 are in constant contact with the pallet, and the bottom of the pallet rubs and presses against the surface of the rollers 8, causing wear or deformation. When it is necessary to replace the protective sleeve 9 on the surface of the rollers 8, first turn the adjustment knob 132. The adjustment knob 132 then drives the rotating rod 131 and the threaded rod 133 to rotate, causing the threaded sleeve 134 to move on the surface of the threaded rod 133. This causes the limiting plate 135 to slide along the inside of the guide groove 136, allowing the limiting plate 135 to detach from the surface of the fixed plate 122. Then, the adjustment knob 132 can be turned... The rotating plate 121 causes the disc 10 to disengage from the limiting groove 123. Then, the disc 10 is lifted, and through the cooperation of universal joint 5, universal joint 7 and cross shaft 6, the roller 8 is deflected around the cross shaft 6, so that the protective sleeve 9 on the surface of the roller 8 can be removed and replaced. After replacement, the reverse operation of the flipping structure 12 is performed, so that the rotating plate 121 and the fixed plate 122 are attached to the surface of the support platform 3, and the disc 10 can be locked between the limiting groove 123 and the semi-circular block 11. At this time, the limiting plate 135 is adjusted by the limiting structure 13 so that the limiting plate 135 is attached to the fixed plate 122, so that it can be used normally in the future.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any indirect modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
