DETAILED DESCRIPTION OF THE EMBODIMENTS
[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0020] Embodiment 1
[0021] Please refer to Figures 1-4 , the present utility model provides the following technical solutions: a hydraulic lifting trolley, including a frame 1, wheels 2 are installed at the bottom end of the frame 1, a lifting frame 3 is slidably connected to the front surface of the frame 1, a hydraulic cylinder 4 is assembled inside the frame 1, and a connecting rod 5 is connected to the telescopic end of the hydraulic cylinder 4; both ends of the connecting rod 5 are connected with chains 6, the chains 6 are connected to the lifting frame 3, a support plate 7 is connected to the surface of the lifting frame 3, a push handle 16 is connected to the back end of the frame 1, extension plates 8 are movably connected to both sides of the support plate 7, a pressing bolt 9 is connected to the bottom end of the support plate 7, and a fixed pedal 15 is also connected to the bottom end of the frame 1.
[0022] Preferably: The lifting frame 3 is connected to the frame 1 in a lifting manner through the chains 6 and the hydraulic cylinder 4, and the support plate 7 is fixedly connected to the lifting frame 3 through screws.
[0023] In the embodiment, the working principle of the hydraulic lifting trolley is described. First, the hydraulic lifting trolley can be pushed to any place by using the push handle 16 and the wheels 2. Then, the lifting of the hydraulic cylinder 4 can push the connecting rod 5 to rise. At the same time, the rising of the connecting rod 5 drives the movement of the chains 6. Subsequently, the chains 6 will drive the lifting frame 3 to move, thereby adjusting the position of the lifting frame 3. Then, the support plate 7 can be fixed on the lifting frame 3 by using screws. Then, the hydraulic lifting trolley is pushed by using the push handle 16 and the wheels 2 to push the support plate 7 under the item. Then, the hydraulic cylinder 4 works to lift the support plate 7, thereby completing the work of taking out the item. Then, the telescopic end of the hydraulic cylinder 4 retracts to drive the support plate 7 to descend. Secondly, the fixed pedal 15 can be used to brake the movement of the hydraulic lifting trolley.
[0024] It should be supplemented and explained that: This hydraulic lifting trolley is customized for the lifting of the fan inverter power module after it is removed from the inverter cabinet. It is a lifting tool made to avoid manual handling and effectively reduces the workload of manual handling.
[0025] Embodiment 2
[0026] Please refer to Figures 1-4 , the extension plates 8 are connected to the support plate 7 in a squeezing and fixing manner through the pressing bolts 9.
[0027] In the embodiment, as described in Embodiment 1, when the usable area of the support plate 7 is insufficient, the rotatable extrusion bolt 9 can be used to release the extrusion fixation of the extension plate 8, and then the extension plate 8 is pulled outwards. Subsequently, the usable area of the support plate 7 is increased through the extension plate 8, which facilitates the lifting of items of different volumes and avoids the situation where the item is suspended due to the insufficient usable area of the support plate 7, thereby reducing the safety hazard of the item falling.
[0028] Embodiment 3
[0029] Please refer to Figures 1-4 , a through hole 10 is formed through the surface of the support plate 7, and two fixing blocks 11 symmetrical about the longitudinal bisector line of the through hole 10 are further connected to the bottom end of the support plate 7. A threaded rod 12 is connected between the two fixing blocks 11. One end of the threaded rod 12 is connected to a bearing 13, and a push plate 14 is threadedly connected to the surface of the threaded rod 12.
[0030] Preferably: The threaded rod 12 is rotatably connected to the fixing block 11 through the bearing 13.
[0031] Preferably: The push plate 14 is in threaded motion with the support plate 7 through the threaded rod 12.
[0032] In the embodiment, as described in Embodiment 1, when taking and placing an item on the support plate 7, at this time, the threaded rod 12 can be rotated to rotate within the inner ring of the bearing 13, and then the push plate 14 advances along the thread on the surface of the threaded rod 12. Consequently, the push plate 14 advances in the through hole 10. At the same time, the push plate 14 is higher than the support plate 7, so the push plate 14 pushes the item closer to the front end of the support plate 7, facilitating the manual removal of the item on the support plate 7 and thus improving the convenience of item removal.
[0033] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
