Description

technical field

[0001] The invention belongs to the technical field of lifting equipment, and in particular relates to a semi-automatic lifting device. Background technique

[0002] In modern industrial production, lifting equipment is widely used, such as rail lifts, scissor lifts, etc., basically using various driving parts to drive, such as hydraulic cylinders, pneumatic cylinders, etc.

[0003] For example, the glass lifting device disclosed in Chinese patent CN207030428U includes a driving device, a driving plate and a plurality of lifting columns. One end is fixed on the driving plate, and the free end of the lifting column is accommodated in the glass printing table. The driving device is used to drive the driving plate to move close to or away from the glass printing table. When the driving plate moves close to the glass printing table, the free end of the lifting column Pass through the glass printing table and protrude over the top of the glass printing table to l...
