Diesel engine cylinder sleeve lifting appliance and lifting method

Abstract

The invention discloses a diesel engine cylinder sleeve lifting appliance which comprises a lifting screw and nut group, a central suspension rod, a balance frame assembly and a fixed cross rod assembly. The center of the balance frame assembly is supported on the upper part of the central suspension rod in a manner of being capable of sliding up and down, and the bottom of the central suspensionrod is closed through a stuffy cover. The fixed cross rod assembly transversely penetrates a cylinder sleeve and the lower end of the central suspension rod to be fixedly connected with the cylinder sleeve. The outer end of the balance frame assembly evenly abuts against the outer peripheral surface of an upper end port of the cylinder sleeve, and a limiting block transversely penetrates the lowerpart of the central suspension rod and is vertically and fixedly connected with the lower part of the central suspension rod. A lifting method comprises the following steps of (1) installing the central suspension rod into the cylinder sleeve, (2) installing the balance frame assembly, (3) enabling a steel sleeve outer circle supporting assembly to abut against the outer peripheral surface of theupper end of the cylinder sleeve, and (4) lifting the cylinder sleeve. The lifting appliance is simple in structure and good in versatility. The cylinder sleeve is conveniently and quickly lifted, the risk of collision damage to the cylinder sleeve is avoided, and the lifting efficiency is improved.

Description

technical field [0001] The invention relates to a special clamp for diesel engine components, in particular to a special hanger and a lifting method for a diesel engine cylinder liner, and belongs to the technical field of diesel engine manufacturing. Background technique [0002] The power and safety of the diesel engine are the key factors to ensure its normal operation and prolong its service life. However, the important part that directly determines the power performance of the diesel engine is the combustion chamber structure, including the cylinder liner. The cylinder liner is a thin-walled cylindrical part. Its processing The dimensional accuracy, shape and position tolerance and surface roughness requirements are very high, and multiple processes are required to complete the processing. It needs to be handled many times in the process of processing and assembly. It is difficult to lift with conventional lifting gear. If the lifting is not done properly, the cylinder ...

AI Technical Summary

Problems solved by technology

It needs to be handled many times in the process of processing and assembly. It is difficult to lift with conventional lifting gear. If the lifting is not done properly, the cylinder liner is easily deformed. Once the deformation of the cylinder liner exceeds the tolerance, it will lead to scrapping and increase the manufacturing cost of the whole machine. and delayed delivery
