As depicted in figs. 1 and 2, the displacement method of the lifting of embodiment of the present invention auxiliary hoist peculiar to vessel, including it is as follows
Step:
Main crane is sling 3 complete machine of auxiliary hoist using hoisting appliance 1；
Main crane amplitude variation revolution is to be moved to target position for auxiliary hoist 3.
The displacement method of the embodiment of the present invention can directly using main crane by 3 complete machine of auxiliary hoist sling then into
Row complete machine displacement, then auxiliary hoist moved on crane ship or afloat crane ship between move when be just not necessarily to by
Auxiliary hoist, which is broken up, to be re-assemblied to improve efficiency, and facilitates displacement.
In the present embodiment, main crane amplitude variation revolution includes main crane so that auxiliary hoist is moved to target position
Luffing is turned round so that the initial position on the crane ship where auxiliary hoist from auxiliary hoist to be moved to the mesh on crane ship
Initial position on crane ship where auxiliary hoist from auxiliary hoist is moved on another crane ship by cursor position
Target position.That is when auxiliary hoist 3 needs some position on crane ship to be moved to another location (target
Position) when, unit assembling of ship machinery directly can be carried out by main crane when the barrier encountered on deck can not voluntarily walk.When auxiliary
Help the needs of crane 3 when being moved on the crane ship of another operation on the sea by a crane ship of operation at sea, it can also be with
Integral hoisting is directly carried out as the main crane of the crane ship where the auxiliary hoist and is shifted.
Since the volume and weight of auxiliary hoist are all larger, in order to improve the stability in shifting process, the present embodiment
Displacement method further include before main crane is sling 3 complete machine of auxiliary hoist using hoisting appliance 1 by hoisting appliance 1 with
Auxiliary hoist turntable 31 is connected at least three lifting tie point A and adjusts the center of gravity of auxiliary hoist 3 at least three

Main crane and auxiliary hoist 3, are set on crane ship；With
Hoisting appliance 1, for being connect with the suspension hook 2 of main crane and auxiliary hoist 3 so that main crane is to assisting
Heavy-duty machine 3 carries out complete machine displacement.
The lifting boat system directly carries out complete machine displacement to auxiliary hoist 3 using main crane and hoisting appliance 1, then
Auxiliary hoist moved on crane ship or afloat crane ship between move when be just not necessarily to break up auxiliary hoist
It re-assemblies to improve efficiency, facilitates displacement.
As shown in figure 3, the hoisting appliance of the present embodiment includes:
Suspender belt connection component 11, for being connect with main crane；With
Equalizer bar 13, for connecting suspender belt connection component 11 and auxiliary hoist 3.
Equalizer bar 13 has at least three lifting tie points connecting with auxiliary hoist 3.The center of gravity position of auxiliary hoist 3
The lifting stability and safety of auxiliary hoist are improved within the span of at least three lifting tie points.
As shown in figure 3, removably being connected between the suspender belt connection component 11 and equalizer bar 13 of the present embodiment by shackle 12
It connects.
As shown in figure 4, the equalizer bar 13 of the present embodiment includes square frame structure, there are four liftings for square frame structure tool
Tie point.
Square frame structure includes circumferentially successively enclosing the circumferential connecting rod 131 of connection and being set to inside and intersect
The middle brace rod 132 of setting.
Hoisting appliance 1 further includes the pulling plate component being set between equalizer bar 13 and auxiliary hoist 3, and pulling plate component includes
At least three pulling plate groups 14 being correspondingly arranged at least three lifting tie points.
As shown in figure 4, four upper ear plates 133 and four lower ears on the downside of it that equalizer bar 13 includes side disposed thereon
Plate 134.Equalizer bar 13 by upper ear plate 133 and suspender belt connection component 11 carry out hingedly, by lower ear plate 134 and pulling plate group 14 into
Row is hinged.
Pulling plate group 14 includes sequentially connected at least two pulling plate and the switching part 144 positioned at end, 144 phase of switching part
Pulling plate is rotatably arranged.
Specifically in the present embodiment, pulling plate group 14 includes spaced single pulling plate 141 and double pulling plates 142.Pulling plate group 14
End be provided with switching part.In order to guarantee that pulling plate multivariant can rotate, the head-tail of pulling plate respectively has a switching
Portion, switching part be also to be connect by pin shaft with other pulling plates.And between single pulling plate 141 and double pulling plates 142 and pulling plate group 14
It is connect by pin shaft between the single pulling plate 141 for being located at end.
As shown in fig. 6, the switching part 144 of the present embodiment includes the first pinboard and the second switching that parallel interval is arranged
Plate and third pinboard, the second pinboard and third pinboard are perpendicular to the first pinboard.
Finally it should be noted that: the above embodiments are merely illustrative of the technical scheme of the present invention and are not intended to be limiting thereof；To the greatest extent
The present invention is described in detail with reference to preferred embodiments for pipe, it should be understood by those ordinary skilled in the art that: still
It can modify to a specific embodiment of the invention or some technical features can be equivalently replaced；Without departing from this hair
The spirit of bright technical solution should all cover within the scope of the technical scheme claimed by the invention.
