Problems solved by technology

Since the frequency modulation wheel cannot be directly lifted vertically to the installation position, the installation workers must use ropes to pull it under the frequency modulation wheel, which is inefficient, difficult to install, and has a small operating space, increasing potential safety hazards. Difficult to install in place
Thereby increasing the operation difficulty of the installation workers, and there are serious safety hazards

Abstract

The invention discloses a marine diesel engine frequency modulation wheel lifting tool which comprises a cross beam, a frequency modulation wheel lifting chain, a balancing weight lifting chain, a balancing weight and a balancing weight position adjusting device. The cross beam comprises two steel channels, a lifting transverse pin and a frequency modulation wheel lifting plate, the two ends of the lifting transverse pin are respectively welded to the corresponding steel channels, the upper end of the frequency modulation wheel lifting chain is hooked at the lower end of the frequency modulation wheel lifting plate, the lower end of the frequency modulation wheel lifting chain is screwed into a frequency modulation wheel, the balancing weight position adjusting device is arranged on the upper side of the other end of the cross beam, the upper end of the balancing weight lifting chain is hooked on the lower side of the balancing weight position adjusting device, and the lower end of thebalancing weight lifting chain is screwed into the balancing weight. A lifting method comprises the following steps that (1) the lifting tool is assembled; (2) the position of a lifting point of thebalancing weight on the cross beam is determined; (3) the frequency modulation wheel and the balancing weight are respectively connected; and (4) the two ends of the cross beam are used for carrying the balancing weight and the frequency modulation wheel to move into a mounting position of the frequency modulation wheel correspondingly. The marine diesel engine frequency modulation wheel lifting tool is good in universality, the mounting efficiency is remarkably improved, the mounting cost is reduced, and the lifting problems of assembly and replacement of the frequency modulation wheel aftera whole marine diesel engine is assembled are effectively solved.

Description

technical field [0001] The invention relates to a lifting tool and method for diesel engine components, in particular to a lifting tool that needs to install the frequency modulation wheel whose mass is calculated according to the vibration of the shaft system to the marine diesel engine after the vibration test of the marine diesel engine bench A lifting method and a lifting method belong to the technical field of lifting. Background technique [0002] The torsional vibration generated when the marine diesel engine is running is one of the most important vibrations of the diesel engine. The torsional vibration will cause the transmission between the diesel engine components to be unstable and generate noise, and even cause the shaft to fail due to fatigue damage. Therefore, marine diesel engine manufacturers will calculate according to the shafting configuration of the ship, and select the most suitable frequency modulation wheel and flywheel to avoid torsional vibration of...
