Hoisting mounting method and hoisting mounting fixture for torsional vibration damper

Abstract

The invention discloses a hoisting mounting fixture for a torsional vibration damper. The hoisting mounting fixture comprises a plurality of hoisting supports and at least two fastening screws, each hoisting support is in a T shape and comprises a lower clamping seat and a pair of hoisting steel wire rope clamping plates upwardly and vertically extending from the longitudinal upper middle of the lower clamping seat, each lower clamping seat clamps the peripheral edge of the torsional vibration damper, and ends of the fastening screws respectively penetrate one side of each lower clamping seat to be abutted against the lateral side of the outer edge of the torsional vibration damper. A hoisting mounting method includes the steps: 1) hoisting the torsional vibration damper in horizontal arrangement; 2) mounting the hoisting supports; 3) vertically hoisting the torsional vibration damper; 4) aligning a center hole of the torsional vibration damper to a mounting flange of a crankshaft end face; 5) pulling the torsional vibration damper to sleeve the mounting flange of the crankshaft end face; 6) fixing the torsional vibration damper to the crankshaft end. The hoisting mounting fixture guarantees hoisting safety, the hoisting mounting method is simple, easy and feasible, mounting efficiency is improved, and the problem of inconvenience in mounting of the torsional vibration damper due to lack of hoisting holes is solved.

Description

technical field [0001] The invention relates to a lifting and installing tool for marine low-speed diesel engine parts, especially a lifting and installing tool for a torsional vibration damper, and also relates to a method for lifting and installing the torsional vibration damper on the end of a crankshaft, which belongs to special tools for lifting technology field. Background technique [0002] The torsional vibration damper is an important part used to eliminate the torsional vibration of the diesel engine. During the operation of the diesel engine, if there is a problem of excessive torsional vibration, it will cause adverse effects such as the movement of the main shaft and unstable speed regulation of the main engine. Vibration dampers to eliminate torsional vibrations. [0003] When the diesel engine is installed and debugged in the factory, it is sometimes necessary to install a torsional vibration damper at the end of the crankshaft. The commonly used torsional vi...

Problems solved by technology

In the prior art, the hoisting wire rope is directly used to wind the silicone oil shock absorber shell for a week to lift vertically. This vertical lifting method has a major safety hazard of the lifting wire rope slipping off. In the circumferential direction of the shell, it is also difficult to rotate the silicone oil shock absorber shell in a small amount, which makes it difficult for the multiple mounting holes of the torsional vibration damper to align with the multiple crankshaft through holes of the crankshaft end, which increases the difficulty of assembly. Reduced torsional vibration damper installation efficiency
