Description

Technical Field

[0001] The utility model relates to the technical field of lifting devices, in particular to a lifting device for a strip steel light-load pallet. Background Art

[0002] Lifting devices usually refer to equipment used to transport objects or people vertically, such as elevators, lifts, etc. They are usually composed of motors, guide rails and other components, and can move up and down at a certain height to facilitate adjusting the goods to a specified height.

[0003] The existing Chinese utility model patent with reference announcement number: CN220076762U discloses a rotary lifting device for strip steel bundling, characterized in that it includes a base, a cross arm mounting seat, a straight arm mounting seat, a cross arm, a straight arm, a first rotating assembly, a second rotating assembly, and a lifting assembly; the cross arm mounting seat is arranged above the base through the first rotating assembly; the straight arm mounting seat is arranged above the cross arm mounting seat through the second rotating assembly. In the utility model, both the straight arm and the cross arm can be rotated, and the spring anti-loosening pressure foot of the straight arm structure is located above the feeding cross arm, and the lifting assembly is located below the straight arm, which can realize the up and down lifting of the straight arm, and the lower part of the feeding cross arm is the supporting base. By rotating the clamping device on the straight arm, the steel coil on the cross arm can be clamped to prevent the steel coil from spreading, so as to cooperate with it to complete the bundling operation.

[0004] Existing lifting devices generally adjust the height of the pallet through hydraulic equipment. Since the hydraulic equipment itself requires a certain space for installation, the minimum distance between the pallet and the ground will be too high. When the strip steel is transferred to the top of the pallet, it is necessary to lift it to a certain height by forklifts and other equipment, which is very inconvenient. At the same time, the connection area between the bottom of the pallet and the hydraulic equipment of the existing lifting device is small. During the lifting process, there is no supporting structure at the bottom of the pallet, which may cause the center of the pallet to be concave when subjected to force. Utility Model Content

[0015] Compared with the prior art, the utility model provides a lifting device for a light-loaded steel tray, which has the following beneficial effects:

[0016] 1. The utility model sets a horizontal piston.
