Abstract

The invention relates to the technical field of mechanical processing, and in particular relates to a vertical lifting device for a workpiece. The device comprises a main lifting rod and the workpiece; a pulling rod is arranged in the main lifting rod; a groove is formed in the main lifting rod; a transverse pin is fixed on the pulling rod; an upper positioning plate and a lower positioning plate are arranged on the main lifting rod; a circular plate is arranged at the tail end of the pulling rod; a supporting seat is arranged on the lower positioning plate; a lifting claw is arranged on the supporting seat; a bulge is arranged at the outer edge of the circular plate and clamped into the groove in the lifting claw. When in use, the device does not damage a circular pipe to be lifted, and moreover, the center of gravity of the device in lifting is in a vertical position, so that the pipe can be avoided lifting during being lifted; in addition, the device is simple in structure, simple and ingenious in design, meets the requirement on lifting any pipe, and is good in use effect.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a workpiece vertical lifting device. Background technique [0002] Due to the needs of processing, large cylindrical workpieces need to be lifted vertically. If there is no such lifting tool, two hooks made of round steel are used to lift the workpiece vertically from the bottom of the inner hole. The disadvantage is that it is round when lifting. Steel is easy to tilt, and the workpiece cannot be vertical every time, that is, it cannot be guaranteed that the lifting point is at the center of gravity of the workpiece every time. Contents of the invention [0003] In order to overcome the existing disadvantages that the round steel pipe is easy to incline when hoisting and the workpiece is not vertical when hoisting, the invention provides a vertical hoisting device for the workpiece. [0004] The technical solution adopted by the present invention to solve the te...
