[0004] In order to solve the problem that the vacuum sintering furnace loading and unloading lifting vehicle in the prior art occupies a large space and has a high cost, a simple lifting loading and unloading trolley is provided.
[0005] The technical solutions adopted in this utility model are as follows:
[0006] A simple lifting and unloading furnace cart includes a bottom frame structure, a middle support structure and an upper pallet structure connected in sequence from bottom to top, the bottom frame structure includes bottom angle steels, bottom cross beams are connected between the bottom angle steels, and the bottom of the bottom angle steels is connected to a moving wheel, the middle support structure includes columns fixedly connected to the bottom cross beams, middle angle steel brackets are connected between the columns, middle cross beams are also connected between the columns above the middle angle steel brackets, a jack is connected to the middle cross beam, the upper pallet structure includes an upper pallet fixedly connected to the jack, and the bottom of the upper pallet is connected to a lifting guide rod inserted into the column.
[0007] Furthermore, the movable wheel includes a locking directional wheel and a locking universal wheel, and two locking directional wheels and two locking universal wheels are respectively provided at the bottom of the bottom angle steel.
[0008] Furthermore, four upright posts and four lifting guide rods are provided respectively, and the lifting guide rods are seamless steel pipes, and the lifting guide rods are welded to the upper support plate.
[0009] Furthermore, two guide bars are symmetrically arranged on the surface of the upper support plate, and a plurality of roller shafts are evenly spaced on the guide bars, and each of the roller shafts is connected to a rolling bearing.
[0010] Furthermore, one end of the upper support plate is connected to an operating rod arranged in a vertical direction.
[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:
[0012] 1. The utility model has a simple structure, low cost, small space occupation, and is economical and practical;
[0013] This trolley not only simplifies the complex structure of traditional lift carts but also reduces production costs, making it easier to mass-produce and market. It occupies minimal space, maximizing space savings and improving space utilization. This allows users to more efficiently manage their workspace and reduces maintenance costs.

[0015] 2. The hand-cranked jack is used to lift and unload the furnace support plate, which is flexible and convenient.
[0016] Traditional lift carts rely on electric or hydraulic power, increasing complexity and cost while also potentially limiting their operation in certain situations, such as power outages or hydraulic leaks. This product, however, utilizes a manual crank jack design, eliminating the need for an external power source or hydraulic system; simply manual operation enables lifting. This design not only reduces equipment failure rates but also improves ease of use. Furthermore, the manual crank jack design ensures a smoother and more controllable lifting process. Users can adjust the height and speed of the lift at any time, ensuring stability and safety during the lifting process. BRIEF DESCRIPTION OF THE DRAWINGS
