Description

Technical Field

[0001] The utility model relates to the technical field of hoisting devices, in particular to an inverted hanging structure of a conveyor. Background Art

[0002] In the field of lifting technology, the traditional lifting method is generally to use slings, chains to bundle or add lifting process holes to lift the workpiece. The auxiliary operation time of this lifting method is long and the operation efficiency is low. In addition, it is very difficult to lift and clamp blanks and special-shaped workpieces, and there are great safety risks. There are even some blanks that cannot be added with process holes, which cannot be lifted using the above methods. Forklifts and other equipment are required to assist in transportation and clamping, which is costly and has poor operability. Large circular workpieces cannot be bundled and lifted. Therefore, at this stage, some lifting devices for fixing and clamping workpieces are used. They can quickly fix the workpieces and can be easily connected to the crane, which can greatly improve the lifting efficiency. However, for workpieces with large thickness differences and that need to be lifted frequently, there is a lack of universal lifting devices that can adjust the clamping height during lifting, transportation, loading and unloading operations.

[0003] Patent publication number CN211594769U discloses a hoisting device, which belongs to the field of hoisting technology and includes a main frame, a support platform for supporting a workpiece at the bottom of the main frame, an adjustable support plate that can be moved in a vertical direction on the main frame, a locking buckle rotatably connected to the adjustable support plate on the adjustable support plate, one end of the locking buckle is a pressing portion that contacts the workpiece, and the other end of the locking buckle is provided with a hoisting connection portion; the utility model utilizes the adjustable support plate that can be moved in the vertical direction on the main frame to adjust the height of the locking buckle, and for workpieces of different thicknesses, the pressing portion of the locking buckle can always be pressed against the surface of the workpiece, thereby quickly hoisting workpieces of different thicknesses and reducing the number of hoisting tools;

[0004] However, the two side slings of the above patent are operated separately, which makes the lifting and operation inconvenient, and the adjustment range is step-by-step adjustment, which has a limited scope of application. Utility Model Content
