Work process of the present utility model:

Being provided with door seat frame 1 on hull 17, door seat frame 1 is arranged above fixing pillar 2, fixing pillar 2 Installed above have slew gear 3, and slew gear 3 is installed above luffing hydraulic wireline winch 5, is wound on luffing liquid Variable-amplitude steel wire rope 10 on pressure winch 5 is with the luffing fixed pulley 8 on convolution pillar 6, jib boom 11 The order of the lifting hook pulley assembly 13 of front sets up, and front end is fixed on lifting hook pulley assembly 13, and And, batch variable-amplitude steel wire rope 10, hanging of the front of pull-up jib boom 11 by luffing hydraulic wireline winch 5 Hook pulley assembly 13, therefore, jib boom 11 swings centered by support shaft 18 upward, makes front end Rise, on the other hand, utilize luffing hydraulic wireline winch 5 to extract variable-amplitude steel wire rope 10 out and make variable-amplitude steel wire rope 10 Lax, the lifting hook pulley assembly 13 of the front of jib boom 11 hangs, therefore, and jib boom 11 swing downwards centered by support shaft 18, make front end decline, and so, jib boom 11 is by becoming The batching or extract out and carry out pitching motion of the variable-amplitude steel wire rope 10 that width hydraulic wireline winch 5 is carried out；

When above-mentioned slew gear 3 works, loop wheel machine rotates together with base plate 31, drives top to guide bar 38 to carry out Moment of torsion transmits, and drives disk 373 to rotate, and upper rotor 372 rotates therewith, thus ensures that slip ring box 37 can To rotate with base plate 31, electric energy can be transmitted by the loop wheel machine on base plate 31 during rotation, it is achieved that crane Full circle swinging function；

Generally under state, when hydraulic system does not works, (include the situation that hydraulic system breaks down), sub, female Friction plate mutually compresses under butterfly spring 415 pressure effect, i.e. clutch apparatus 403 is in normally off, Friction plate phase mutual friction the most sub, female, two grades of axle first gears 404 are rubbed by son, mother with two grades of axles 414 The frictional force of pad links together, two grades of axle first gears 404 drive two grades of axles 414, then drive two grades Axle the second gear 416 rotates, and two grades of axle second gears 416 drive the three grades of axle teeth arranged on three grades of axles 401 Wheel 412, makes three grades of axles 401 rotate, so that the limit speed for braking condition device 413 arranged on three grades of axles 401 brakes；

When clutch apparatus 403 is to be opened, hydraulic system is started working, and clutch plunger set 402 is at hydraulic pressure Moving right under oil effect, do not have pressure between friction plate, female, friction plate, female separates, i.e. Two grades of axles 414 disengage with two grades of axle first gears 404 and couple.Now limit speed for braking condition device 413 does not works, Hydraulic motor 406 band movable reel 418 rotates, and lifting wire rope 9 is wound around on reel 418 and tightens up, lifting Steel wire rope 9, by lifting fixed pulley 7, lifting hook pulley assembly 13, makes suspension hook 12 rise with goods；Rise Fall steel wire rope 9 is decontroled on reel 418, and lifting wire rope 9 is by lifting fixed pulley 7, lifting hook pulley assembly 13, make suspension hook 12 decline with goods；The normal folding and unfolding work of lifting wire rope 9, it is achieved suspension hook 12 Effectively rise at differing heights, decline；

When clutch apparatus 403 is to be closed, under the effect of butterfly spring 415, clutch plunger set 402 In hydraulic oil be discharged, clutch plunger set 402 compresses son, female friction plate again simultaneously, makes braking limit Speed variator 413 brakes, and makes reel 418 stop operating, and lifting wire rope 9 stops being wound around on reel 418, Suspension hook 12 stops rising, declining.

It follows that this utility model provides a kind of ship's crane, use monoblock type revolution to drive, reduce Complete machine height, the batching or extract out and enter of the variable-amplitude steel wire rope that jib boom is carried out by luffing hydraulic wireline winch Row pitching motion；The raise-lower hydraulic winch installed, can realize the vertical lift of weight；There is simple in construction tight Gathering, the afterbody radius of gyration is little, and complete machine cost is low, and freight is low, and Assembling is convenient, and work efficiency is high Advantage.
