Technical Field

[0001] This utility model relates to the field of transportation technology, specifically to a lifting device. Background Technology

[0002] In the cigarette production process, maintenance of certain equipment is required, such as the filter rod launching unit. This module needs cleaning and maintenance at least twice a year. Before maintenance, the launching unit must be removed from the machine, and after cleaning and maintenance, it must be reinstalled on the launching machine. This process usually requires the combined efforts of multiple people to move it. A utility model with publication number CN209481079 U describes a small, easily movable lifting device, including a base and a lifting mechanism. The lifting mechanism is fixedly connected to the base, and a traveling mechanism is connected to the side wall of the base via a rotating rod. A locking nut is connected to the outer wall of the rotating rod, and a hydraulic lifting column is provided on the upper surface of the base. However, this lifting device has limited freedom of movement, only allowing for lifting operations and unable to change the lifting height of the boom or perform rotation operations, making operation in confined spaces difficult. Therefore, this utility model provides a lifting device that allows for changing the lifting height and rotation, thereby increasing the freedom of movement of the lifting device. Utility Model Content

The rotating base plate 9 is slidably connected to the two sides of the support plate mechanism, thereby increasing the fulcrum and preventing the lifting device from tilting and falling over. In addition, the rotating base plate 9 is provided with a storage compartment 17 for storing tools and items.

[0021] The base 1 includes an upper base plate 1c, a lower base plate 1a, and connecting columns 1b.
