Multi-degree-of-freedom adjustable centering hoisting device

Abstract

The invention discloses a multi-degree-of-freedom adjustable centering hoisting device which comprises a cross beam, a side beam and a moving beam, the moving beam is slidably connected with the side beam, the lower surface of the moving beam is fixedly connected with an electric hoist lifting device, and a steel wire rope of the electric hoist lifting device is connected with a fixed pulley block and a movable pulley block in a winding mode. A rotary supporting table is fixedly connected to the bottom end of the movable pulley block, a rotary box is rotationally connected to an annular step of the rotary supporting table, a lifting beam is fixedly connected to the lower surface of the rotary box, telescopic columns are slidably connected to the two side walls of the lifting beam, and double-lug hinge supports are arranged on the lower surfaces of the tail ends of the telescopic columns; a winding roller is connected between lug plates of the double-lug hinge support through a rotating shaft, a buffer column is bound to the tail end of a lifting rope on the winding roller, and a lifting hook is connected to the tail end of the buffer column through the lifting rope. The centering lifting device has the advantages that irregular workpieces can be centered and lifted, the stability is good during lifting, and safe lifting of the workpieces is ensured.

Description

technical field [0001] The invention relates to the technical field of hoisting, in particular to a multi-degree-of-freedom adjustable centering hoisting device. Background technique [0002] As the structure of the workpiece is becoming more complex and large, the workpiece needs to be moved with the help of a lifting device during the process of transportation and handling. The existing lifting device is usually equipped with two moving beams, and the lower end of the moving beam There is an electric hoist, the hook of the electric hoist is used to connect the workpiece, and the workpiece is hoisted by the electric hoist. However, irregular workpieces cannot be centered and hoisted, and the stability of the hoisting is poor, and the workpiece is overweight to a large extent. The sling or wire rope is broken, which cannot ensure the safe lifting of the workpiece, the swing time of the workpiece is long during hoisting, the swing range of the workpiece is large during hoisti...

[0002] As the structure of the workpiece is becoming more complex and large, the workpiece needs to be moved with the help of a lifting device during the process of conveying and handling. The existing lifting device is usually equipped with two moving beams, and the lower end of the moving beam There is an electric hoist, the hook of the electric hoist is used to connect the workpiece, and the workpiece is hoisted by the electric hoist. However, irregular workpieces cannot be centered and hoisted, and the stability during hoisting is poor, and the workpiece is overweight to a large extent. The sling or wire rope is broken, which cannot ensure the safe lifting of the workpiece, the swing time of the workpiece is long during hoisting, the swing range of the workpiece is large during hoisting, and the lifting motion of the workpiece is not stable, etc.
