Hoisting tool and method for marine low-speed diesel engine electric vibration compensator

Abstract

The invention discloses a hoisting tool for a marine low-speed diesel engine electric vibration compensator. The hoisting tool is in a semi-open door frame shape. The hoisting tool is formed by sequentially welding an upper cross beam, a stand column and a lower cross beam. The upper cross beam is provided with working hoisting holes and a hosting tool hoisting hole. The lower cross beam is provided with a bolt hole used for being connected with the electric vibration compensator. A space defined by the upper cross beam, the lower cross beam and the stand column contains an exhaust collectingpipe of a marine low-speed diesel engine. In the hosting mounting process, the hoisting tool is transversely inserted therein, so that the exhaust collecting pipe is at the middle neutral position ofthe hoisting tool. By means of the hoisting tool, the hosting operation, dismounting operation and mounting operation of the electric vibration compensator can be free of influence of the mounting state of the exhaust collecting pipe; the electric vibration compensator can be directly hoisted in place at a time; the operation procedure is simplified; and operation efficiency is improved.

Description

technical field [0001] The invention relates to a lifting tool, in particular to a lifting tool and a method for a marine low-speed diesel engine electric vibration compensator, belonging to the technical field of lifting. Background technique [0002] At present, the vibration reduction method of the main engine of marine low-speed diesel engine is mainly to install the axial shock absorber on the main engine and the secondary torque compensator at the front and rear ends of the main engine; in the way of reducing the lateral vibration of the main engine, the installation of electric vibration compensator has become more and more More options. However, the installation position of the electric vibration compensator is mostly under the exhaust header, and the disassembly process is affected by the exhaust header. Since there is no vertical lifting space, it is impossible to directly use the lifting lugs of the electric vibration compensator itself. . Therefore, at this sta...
