The course of work of the present invention：
During present invention work, the piston rod of principal arm oil cylinder 5, which is stretched out, makes principal arm 8 steeve, then luffing jib is oily
The piston rod of cylinder 9, which stretches out, makes luffing jib 13 steeve, and the present invention is returned back into job position, hydraulic wireline winch is utilized
4 or hydraulic winch 6 carry out weight lifting operation, state is as shown in Figure 1 after lifting；Hoisting heavy is returned
Go to after job position, weight vertical drop can be made to ground by hydraulic wireline winch 4 or hydraulic winch 6,
The work width of crane can also be changed by the piston rod of principal arm oil cylinder 5 or the piston rod of luffing jib oil cylinder 9
Degree and lifting altitude, by weight-drop to ground；
When above-mentioned slew gear 3 works, loop wheel machine is rotated together with bottom plate 31, drives top guiding bar 38 to carry out
Moment of torsion is transmitted, and drives disk 373 to rotate, upper rotor 372 is rotated therewith, so as to ensure that slip ring box 37 can
To be rotated with bottom plate 31, electric energy can be transmitted to the loop wheel machine on bottom plate 31 during rotation, realize crane
Full circle swinging function；
Under usual state, when hydraulic system does not work (situation for including hydraulic system failure), son, mother
Friction plate is mutually compressed under the effect of the pressure of butterfly spring 415, i.e., clutch apparatus 403 is in normally off,
Now son, female friction plate phase mutual friction, two grades of axle first gears 404 are rubbed with two grades of axles 414 by son, mother
The frictional force of pad links together, and drives two grades of axles 414 by two grades of axle first gears 404, then drive two grades
Axle second gear 416 is rotated, and two grades of axle second gears 416 drive the three-level axle tooth set on three-level axle 401
Wheel 412, rotates three-level axle 401, so that the limit speed for braking condition device 413 set on three-level axle 401 brakes；
When clutch apparatus 403 will be opened, hydraulic system is started working, and clutch plunger set 402 is in hydraulic pressure
Moved right under oil effect, there is no pressure between son, female friction plate now, son, female friction plate are separated, i.e.,
Two grades of axles 414 are disengaged with two grades of axle first gears 404 to be coupled.Now limit speed for braking condition device 413 does not work,
Hydraulic motor 406 is rotated with movable reel 418, and main hook steel wire rope 7 winds on reel 418 and tightened up, main hook
Steel wire rope 7 makes main hook 17 rise with goods by main hook fixed pulley 11, main hook pulley assembly 12；
Main hook steel wire rope 7 is decontroled on reel 418, and main hook steel wire rope 7 passes through main hook fixed pulley 11, main hook pulley
Component 12, makes main hook 17 decline with goods；The normal folding and unfolding work of main hook steel wire rope 7, realizes main hook
17 effectively rise in different height, decline；
When clutch apparatus 403 will be closed, in the presence of butterfly spring 415, clutch plunger set 402
In hydraulic oil be discharged, while clutch plunger set 402 compresses son, female friction plate again, limit braking
Speed variator 413 brakes, and reel 418 is stopped operating, and main hook steel wire rope 7 stops winding on reel 418,
Main hook 17 stops rising, declined；
When hydraulic system can not work, using manual mode.When i.e. hydraulic system breaks down, clutch
Device 403 is closed automatically, and limit speed for braking condition device 413 is started working, and now first installs hand gear 419,
Three-level axle 401 is linked together with hand gear 419, rotate forward shaking of being set on hand gear 419
, main hook steel wire rope 7 is wound on reel 418 and tighten up, main hook 17 rises, completion manual work；
Hydraulic winch 6 employs low speed high torque hydraulic motor 61, can provide enough torques, elevator
Being directly connected to of machine reel 63 and low speed high torque hydraulic motor rotary shaft 68 eliminates decelerator, significantly
The volume and weight of hydraulic winch 6 is reduced, while reducing cost.
It follows that the present invention provides a kind of collapsible crane, using monoblock type revolution driving, reduce whole
Machine height, gate folds arm configuration, reduces complete machine overall dimensions and height, saves installing space, makes a gram order
The structure hung simplifies, reliability is improved, while larger work range and lifting altitude can be met, function admirable,
Reliability is high, and it is convenient to manipulate, it is easy to maintaining；The relative position setting of principal arm, luffing jib, is optimized
The carrying stress of principal arm oil cylinder and luffing jib oil cylinder, keeps the operating pressure of principal arm oil cylinder and luffing jib oil cylinder
Unanimously, hydraulic work system Rational Matching of Parameters；Hydraulic wireline winch, the hydraulic winch of installation, can realize weight
The vertical lift of thing；With compact conformation, installation, easy to use, cost is low, the high advantage of operating efficiency.
