[0015] (III) Beneficial effects Compared with the prior art, the present invention provides a lifting device for transferring modular components of a high-precision vacuum chamber, which has the following beneficial effects: 1. The modular components of the high-precision vacuum chamber are transferred using a lifting device. By providing an adjusting pulley and a threaded rod, when the weight in the placement chassis is unbalanced, the second connecting rope and the first connecting rope can be used in conjunction with the first gear plate and the second gear plate and other components to adjust the inclination of the placement chassis. After the adjustment, the extrusion plate and the pressure ring are used to limit the position of the center block to ensure the overall stability of the placement chassis, reduce the possibility of collision between components inside the placement chassis, and improve the stability of equipment transportation. At the same time, the high friction of the rubber pad and the blocking of the clamping plate can further reduce the possibility of collision between components and improve the stability of component transportation.

[0016] 2. The high-precision vacuum chamber modular components are transferred using lifting equipment. A limiting rod and an adjusting pulley are provided. During the equipment transportation process, there may be a weight imbalance inside the base frame, which may cause the equipment to rotate. The limiting rod can be used to limit the equipment from rotating. At the same time, the limiting pulley can be used to limit the equipment, which can improve the stability of the equipment and reduce the possibility of rotation.

[0017] 3. The high-precision vacuum chamber modular assembly is transferred using a lifting device. By providing an adjusting pulley and a stop block, the first connecting rope and the second connecting rope are prone to wear during long-term use. The adjusting pulley and the stop block can prevent the first connecting rope and the second connecting rope from contacting other sharp or rough surfaces, thereby improving the durability of the first connecting rope and the second connecting rope.

[0024] In the present invention, when in use, the components that need to be transported can be placed in the rubber pad 3, and then the clamping plate 5 can be clamped as needed.

At this time, the left and right sides of the placement chassis 1 tend to be balanced. When the placement chassis 1 is balanced, the control motor 29 can be started so that the control motor 29 drives the threaded rod 31 to rotate, and the threaded rod 31 drives the pressure ring 32 and the extrusion plate 30, so that the extrusion plate 30 and the pressure ring 32 fix the center block 28, and then fix the balanced state of the placement chassis 1, so that the equipment remains stable.
