Below in conjunction with the accompanying drawings and specific embodiment the present invention is described further, but following embodiments are absolutely not to this hair
It is bright to have any limitation.
As Figure 1-5, the ocean platform crane includes：Lower shell 1, bearing assembly 2, upper shell 3, turntable 4, herringbone
Frame 5, assembly pulley 6, steel wire rope 7, arm support 8, hoist engine and electric rotating machine；
Wherein, the bottom surface of lower shell 1 is fixedly connected on ocean platform；Bearing assembly 2 is cylindrical-shaped structure, and bottom surface is fixed
On the top surface for being connected to lower shell 1, top surface is fixedly connected on the bottom surface of upper shell 3；The bottom surface of turntable 4 is fixedly connected on cylinder
On the top surface of body 3；A-frame 5 includes two A shapes framves 51, and the bottom of two A shapes framves 51 is connected to the top surface two ends of turntable 4
On the A-frame connecting plate 41 being provided with；The wheel shaft of assembly pulley 6 is fixed on the top of A-frame 5, positioned at the company of two A shapes framves 51
Meet place；One end of arm support 8 is pivotally fixedly connected on the side top of turntable 4；One end of steel wire rope 7 is fixed on arm
On the hook of the other end of frame 8, the other end is connected on hoist engine by assembly pulley 6；By hoist engine lay winding wire ropes 7, realize
Rising or falling for hook, drives weight movement of the carry on hook.
Bearing assembly 2 is three row's ball-type pivoting support bearing components, including inner ring 21, outer shroud 22, upper strata cylindrical roller
23rd, radial direction cylindrical roller 24 and lower floor's cylindrical roller 25；The lower end of inner ring 21 is fixedly connected on lower shell 1 by the second bolt 27
Top surface on, the outer end of outer shroud 22 is fixedly connected on the bottom surface of upper shell 3 by the first bolt 26；In the lateral wall of inner ring 21
A boss 28 is horizontally outward extended at middle part, makes the medial surface of the lateral surface and outer shroud 22 of inner ring 21 common in the upper of boss 28
Side, lower section and outside form chamber respectively, and upper strata horizontal cylinder roller 23, lower floor's horizontal cylinder roller 25 and radial direction are placed respectively
Cylindrical roller 24；The inwall of inner ring 21 is provided with ring gear；The outer wall of outer shroud 22 is provided with a rotary support, rotary support
A gear being meshed with the ring gear is connected, and gear is connected with the output shaft of an electric rotating machine, passes through electric rotating
Machine drives pinion rotation.
It is vertically arranged apart from the A shapes frame 51 of arm support 8 farther out, and from top to bottom provided with three cross bars 52；Another A shapes frame 51
It is obliquely installed, and middle part is provided with a cross bar 52.
Arm support 8 is made up of the first end to end successively arm joint 81, the second arm joint 82 and the 3rd arm joint 83；First arm joint 81
Free end be pivotally movably connected in the side top of turntable 4, specifically can by be arranged on the first arm joint 81 from
Realized with being arranged on the arm support connecting plate 42 on the side top of turntable 4 and be flexibly connected by the connecting plate 84 held, connecting plate 84 and arm support
The shape of connecting plate 42 is engaged, and strengthens the stability of connection；The free end fixed hook of 3rd arm joint 83.First arm joint 81,
Second arm joint 82 and the 3rd arm joint 83 are made up of conventional chord member 85 and web member 86, can be according to actual conditions to chord member 85 and web member
86 are designed, for example, can be into identical with the Design of length of the chord member 85 of the 3rd arm joint 83 by the first arm joint 81, the second arm joint 82
, the web member 86 of the first arm joint 81 and the second arm joint 82 is designed to isometric formula, and the web member 86 of the 3rd arm joint 83 is designed to gradually receive
Contracting formula.
Now the operation principle of the ocean platform crane of the present invention is described below：
When needing lifting heavy, first weight is suspended on the hook of the free end of the 3rd arm joint 83, due to hook
It is connected with one end of steel wire rope 7, hoist engine, the other end of lay winding wire ropes 7, therefore steel wire rope 7 is now started by staff
It can be oriented to, be gradually shortened with linking up with one end for being connected to the distance of assembly pulley 6, the 3rd arm joint 83 on arm support 8 by assembly pulley 6
Therefore gradually raise, drive hook and its weight of suspension to be lifted together.
When needing landing weight, principle is identical, and simply the winding direction of hoist engine is on the contrary, will not be repeated here.
When needing weight horizontal rotation, start electric rotating machine first, electric rotating machine is driven on the outer wall of outer shroud 22
Gear starts to rotate.Because gear is engaged with the ring gear of inner ring 21, and inner ring 21 is fixedly connected on lower shell 1, therefore interior
Gear ring remains motionless, and realizes rotation of the gear along ring gear, so as to drive outer shroud 22 to realize indirectly by rotary support
Rotate.Further, since outer shroud 22 is fixedly connected on upper shell 3, therefore upper shell 3 and turntable 4 can be driven to realize simultaneously simultaneously
Rotate, so that the weight of the hook and its suspension on indirect belt swing arm frame 8 realizes horizontal rotation.
During lifting, landing and the horizontal rotation of weight is carried out, bearing assembly 2 may be by plurality magnitude
Both direction axial force, power of tumbling and radial load；Now, the axial moment and tilting moment of both direction can be by upper stratas
Cylindrical roller 23 and lower floor's cylindrical roller 25 are born, and radial direction torque is born by radial direction cylindrical roller 24, and this structure can disperse and subtract
The load of small single rolling element and end face, reduces difficulty and the requirement of quenching processing；In the present invention, using three rows of rollers
Pivoting support, makes each rolling element bearing capacity division of labor clear and definite, the carrying efficiency of each carrying roller is given full play to, with larger axial direction
The bearing capacity of power, radial load and tilting moment, meets requirement of the Offshore Platform crane to pivoting support.
