Specific embodiment
In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, under
Face combines and is specifically illustrating, and the utility model is further described.
Referring to Fig. 1 to Fig. 4, the boom hoisting of A font cantilever crane provided by the utility model comprising hoister winch 2, cantilever crane
4, two pitching oil cylinders 5 and two identical piers 6.
Two piers 6 are symmetricly set on 1 deck of hull, are directly anchored to 1 first of hull especially by welding manner
Plate is close to gunnel position, in this way, since pier 6 can directly weld, nothing the original inside floor of positive hull 1
Aperture or reinforcement are needed, thus work very little is reequiped to hull 1.
In addition, being equipped with the first hinge and the second hinge on pier 6.
Cantilever crane 4 is arranged between two piers 6, and its two sides is cooperatively connected with the first hinge respectively, in this way
Realizing cantilever crane can be rotated between two piers 6, to realize pitching movement.
Cantilever crane 4 is specially A font, so that stall space is opened with biggish in 4 lower part of cantilever crane, when cargo is hung on deck
When upper, it can open in stall space being contained in boom 4 easily.
Pulley structure is equipped on cantilever crane 4, pulley structure is for being cooperatively connected with the wirerope 3 on hoister winch 2.
Pulley structure includes fixed pulley 45 and leading block 44, and fixed pulley 45 is arranged in the top of cantilever crane 4, and leading block
Position 44 is in 45 lower section of fixed pulley, and wirerope 3 can successively be connect with leading block 44 and fixed pulley 45, by along 45 He of fixed pulley
Leading block 44 slides, to realize lifting.
In addition, being equipped with a short beam 42 outstanding at left and right sides of 4 rear of cantilever crane, cut with scissors in 42 end of short beam equipped with third
Point 43, third hinge 43 are used to be cooperatively connected with pitching oil cylinder 5.
Furthermore a crossbeam 46 is equipped between two short beams 42, a crossbeam 46 is for balancing two pitching oil cylinders 5 to respective
The additional moment of hinge keeps stable structure.
Two pitching oil cylinders 5, one end of one of pitching oil cylinder 5 are rotatably arranged on one of pier 6
On the second hinge on, the other end can be rotatably set on one of third hinge 43 of cantilever crane 4, another pitching oil cylinder
5 one end is rotatably arranged on the second hinge on another pier 6, and the other end can be rotatably set in cantilever crane 4
A third hinge 43 on.
In this way, being arranged by above structure, when so that pitching oil cylinder 5 being stretched, cantilever crane 4 can be driven to carry out pitching fortune
It is dynamic.
Hoister winch 2 is arranged on 1 deck of hull, wirerope 3 is equipped on hoister winch 2, in 3 front end of wirerope
Equipped with suspension hook 31, leading block 44 and fixed pulley 45 are sequentially passed through by the wirerope 3 above it, cargo is risen to realize
Liter and lowering operation.
Here is the specific work process of the application:
When pitching oil cylinder 5 is fully extended, cantilever crane 4 can be controlled just at upright state, cargo by hoister winch 2
System, directly from slinging above deck；
After being hung to certain altitude, control pitching oil cylinder 5 is retracted, then cantilever crane 4 starts to face upward under tilting forwards, until wait bow
When facing upward oil cylinder 5 and being fully retracted, at this moment cantilever crane 4 is approximately in horizontality, and 4 upper end of cantilever crane can lean out ship side maximum distance, at this time
Cargo decentralization can be carried out by hoister winch 2；
When cargo recycles, operated by above-mentioned opposite action.
The basic principles and main features of the present invention and the advantages of the present invention have been shown and described above.Current row
