Description
Technical field
The present invention relates to a kind of lifting gears more particularly to a kind of for marine low speed diesel engine electric vibrating compensator
Lifting tool and method belong to lifting technique field.
Background technique
At present marine low speed diesel engine host abatement vibration mode be mainly, on host install axial vibration damper and
Host front and back end is installed by second moment compensator；Abatement host oscillation crosswise mode in, installation electric vibrating compensator at
More and more to select.But the installation site of electric vibrating compensator is mostly in the lower section of exhaust header, disassembly process by
The influence of exhaust header due to the lifting space of not no vertical direction, thus can not directly use electric vibrating compensator itself
The lifting lug lifting having.Therefore, the installation of electric vibrating compensator at this stage does not mostly install preceding progress in exhaust header, at this time may be used
Directly directly to be lifted by crane using the lifting lug of electric vibrating compensator ontology.But later in the operational process of diesel engine,
When needing that electric vibrating compensator is replaced or repaired, it is then not possible to operation is carried out after removing exhaust header again,
Therefore upper borrow suspension centre mostly is pulled in the support of exhaust header using chain block, after electric vibrating compensator is promoted, then in side
The lower section that exhaust header is pulled it using chain block, is then lifted by crane；Installation exercise after replacement or maintenance.
The operation is influenced by exhaust header, is needed using chain block mounting and adjusting, therefore process very complicated, labor efficiency
It is low, and there are some potential safety problemss.
Therefore, it is necessary to a kind of lifting tools of more suitable marine low speed diesel engine electric vibrating compensator, make electronic vibration

Further, the quantity more than one of the work lifting eye, position is in transversely arranged.
Further, the size in the space surrounded by the upper beam, lower beam and column is according to the exhaust header
Diameter determines.
Another technical solution of the invention is：
A kind of hoisting method for marine low speed diesel engine electric vibrating compensator using above-mentioned lifting tool, packet
Include following steps：
1) the lifting tool lifting eye on the upper beam is selected, the lifting tool is hung to the electric vibrating and is compensated
It at device, and is attached by bolt and the threaded hole on the ontology of the electric vibrating compensator, which is mended
Repay the lower part that device is fixedly connected on the lifting tool；
2) the work lifting eye is replaced as lifting point, and the electric vibrating compensator is steadily lifted to the exhaust
The side of collector；
3) sling height is adjusted, the exhaust header is made to be included in the space surrounded by the upper beam, lower beam and column,
And guarantee that the electric vibrating compensator is located at the top of its mounting plane；
4) steady slowly mobile suspension hook, keeps the electric vibrating compensator close to the exhaust header direction, to described
It when electric vibrating compensator is located above its installation site, slowly puts down the electric vibrating compensator and adjusts its position, install
The fixed electric vibrating compensator；
5) the lifting tool lifting eye is replaced as lifting point, removes bolt, and the lifting tool is hung out simultaneously properly
It places and saves.
The present invention has the characteristics that compared to original mounting means：
1. using semi-open door frame structure, exhaust header is in the intermediate neutral gear position of lifting device in hoisting process,
Hoisting process is no longer had an impact, electric vibrating compensator is carried out repeatedly without using chain block to borrow adjustment, thus
Installation process is simplified, this is also key innovations place of the invention；
2. the size in the space surrounded by the upper beam, lower beam and column is selected according to the diameter of exhaust header
It selects, guarantees electric vibrating compensator top and exhaust when taking a seat in place can be made to collect comprising living exhaust header in above-below direction
Pipe is not interfered；
3. when in view of connection and not connected electric vibrating compensator, the position of centre of gravity of lifting tool is different, thus is rising
It hangs and is provided with lifting tool lifting eye and multiple work lifting eyes on tool, overcome centre-of gravity shift under different situations and lifting is made
The security implication of industry ensure that the balance of lifting.
