Hoisting tool for hoisting flywheel disc

Abstract

The invention discloses a hoisting tool which can horizontally hoist a flywheel disc, and the hoisting tool comprises a core shaft component and an expanding head component. The core shaft component comprises a hoisting ring and a core shaft which are fixedly connected; the expanding head component comprises a handle, a pull bar, and a plurality of expanding sheets; the core shaft is sleeved inside the handle; two ends of the pull bar are rotatablely connected with the lower end of the handle and the expanding sheets respectively. The core shaft component and the expanding head component can move mutually in a vertical direction. When a flywheel disc is hoisted by using the hoisting tool of the invention, the flywheel disc is landed in a state parallel to the horizontal plane, which savesa lot of time and energy; and the hoisting tool clamps the flywheel disc firmly, which ensures the security during the hoisting process, prevents abrasion or damage of tracks caused by the contact between a sharp addendum of a flywheel gear ring and the track during hoisting by a traditional hoisting tool, and has good protection effect on the track.

Description

technical field [0001] The invention relates to a sling for hoisting a flywheel, in particular to a sling capable of horizontally hoisting a flywheel. Background technique [0002] In the assembly process of the diesel engine, the assembly of the flywheel is a relatively large part assembly. Auxiliary spreaders are usually required during the assembly of these large parts. Scientific and reasonable auxiliary spreaders can greatly reduce the labor intensity of operators and increase labor efficiency. When dynamically balancing the flywheel, it is necessary to use a spreader to hoist the flywheel from the transport pallet to the flywheel dynamic balancing track. At present, the flywheel on-line method for flywheel dynamic balance and other posts is to use traditional hooks to lift the flywheel, hang the flywheel on the flywheel dynamic balance track in a state of being inclined or the end face of the flywheel is perpendicular to the horizontal plane, and then slowly put the ...

AI Technical Summary

Problems solved by technology

Since this action has to be repeated every time a flywheel is lifted, this process takes a lot of time and energy

And because the hook lifts the flywheel and puts it on the track of the balancing machine, the tooth top of the flywheel ring gear is in contact with the track. Because the tooth top is hard and sharp, the contact area with the track of the balancing machine is small, which is easy to cause damage to the track of the balancing machine and accelerate track wear
