Specific embodiment
In the following, the substantive distinguishing features and advantage of the present invention are further described with reference to example, but not office of the invention
It is limited to listed embodiment.
As shown in figures 1 to 6, a kind of general's pillar ocean platform crane pedestal, the pedestal 1 including taper mesa-shaped structure are used
In turntable 2, kingpost 3, door frame 4, longitudinal leap-preventing device for preventing door frame longitudinal leap that arm support 12 is connected；Wherein,
The top of turntable 2 is connected with the lower part of door frame 4 by four axis pins 21, and turntable 2 is sleeved on general by default post holes 22
On column 3, the lower part of kingpost 3 is fixedly connected with pedestal 1, and door frame 4 is set in outside kingpost 3, and turntable 2 is with door frame 4 by work
Lower bearing component, the upper bearing (metal) component configured at dynamic cooperation can be realized realizes 360 degree of revolutions, lower bearing component peace around kingpost 3
At movable cooperation between turntable and kingpost, upper bearing (metal) component is mounted between top and the kingpost of door frame, such as Fig. 2
Shown, the longitudinal direction leap-preventing device is made of axis pin 5, upper support pipe 6, bolt 7, wherein, upper support pipe 6 is solid by welding
The top of kingpost 3 is scheduled on, installation is by 7 fixed axis pin 5 of bolt on upper support pipe 6, to act the work for reaching longitudinal anti-channeling
With.
Specifically, the upper end of the kingpost 3 has mounting hole, mounting hole described in 6 partial insertion of upper support pipe
In after, with the kingpost 3 by being welded to connect fixation, what radial direction that the axis pin 5 is mounted on the upper support pipe 6 opened up
It in pin shaft hole, and is locked in two close end by bolt 7, prevents from coming off, as shown in figure 3, the upper bearing (metal) component includes MGB
(engineering plastic alloy) thrust bearing 10, between 4 corresponding lower face of the upper end of kingpost 3 and door frame, MGB upper stratas footpath
To bearing 8, MGB lower floors journal bearing 9,8 lower end of MGB upper stratas journal bearing and the upper-end contact of MGB lower floors journal bearing 9, two
Person is placed between door frame 4 and upper support pipe 6, is specially sleeved on outside upper support pipe 6, and MGB thrust bearings 10 are sleeved on MGB lower floors
The outside of journal bearing 9, and the door frame 4 is supported in the upper end of kingpost 3.
The upper support pipe 6 is mainly used for supporting MGB (engineering plastic alloy) upper strata journal bearing 8, MGB (engineering plastics
Expect alloy) lower floor's journal bearing 9, MGB (engineering plastic alloy) thrust bearing 10, by the upper bearing (metal) component, the door frame 4
It can be turned round around the upper support pipe 6.
The turntable 2 connects arm support 12 by axis pin, and MGB (engineering plastic alloy) is equipped between kingpost 3 and turntable 2
Sliding bearing 11, as lower bearing component, as shown in figure 4, by the lower bearing component, turntable 2 realizes that 360 degree are turned round, and upper
Bearing assembly together, realizes the 360 degree of revolutions of axis of turntable with door frame around the kingpost.
When ocean platform crane is in bad working environments, longitudinal random wave force is transferred to pedestal by ship or platform
1, it can cause turntable 2 and door frame 4 that longitudinal random motion occurs.When the length travel of turntable 2 and door frame 4 is larger, longitudinal anti-channeling
The lower end of axis pin 5 on device can be tightly bonded with the upper end formation of door frame 4, can effectively prevent turntable 2 and door frame 4 occur it is larger
Longitudinal movement and depart from kingpost 3, so as to ensure the safety of marine crane structure.
When acting on ship or platform due to horizontal random wave force, the random motion in ship meeting occurred level direction, so
The load suffered with crane work is transferred together afterwards acts on ocean platform, in order to increase crane resistance to capsizing,
In the present invention, the main body of the kingpost 3 is pyramidal structure, and the connection of lower part and pedestal 1 uses the cylindrical portion of cylindrical structure,
Since pedestal 1 is using taper structure, after be connected with cylindrical portion, so gradually increased the sectional area of primary structure member, beneficial to
Transmission of the suffered load to place platform in heavy-duty machine work improves the overturn-preventing ability and stabilization of crane loading process
Property.
Steel plate welding forming, the company of the cylindrical structure may be employed in the cylindrical portion of the cylindrical structure of the kingpost
The cylindrical portion connect can make the impact force of kingpost stress steadily, suffered by reduction emergency situations, be effectively improved crane
Overturn-preventing ability.And pedestal has gradually increased the sectional area of primary structure member, institute in working beneficial to crane using taper structure
The load received is transferred to place platform, improves the overturn-preventing ability and stability of crane loading process.
Due to vibrative mechanism in lifting during, the power born by rope and arm support respectively with pulling force and
The form of pressure is transferred to metal (upper component, and metal (upper component is not subject to tilting moment substantially, and tilting moment is mainly by inciting somebody to action
Army's column 3 is born, the square column pier that comparison land crane uses, as arm support revolution can cause lifting motor spindle institute
Large change occurs for the tilting moment received so as to generate impact, and in the present invention, since kingpost 3 is using the company of cylindrical structure
The connection of the pedestal of socket part and cone-shaped is fixed, and as arm support turns round, the tilting moment size suffered by 3 bottom of kingpost has no larger
Variation, can effectively optimize overturn-preventing ability using the connecting portion of cylindrical structure；The pedestal 1 of cone-shaped is subject to identical to incline simultaneously
When covering torque, transmission of the pyramidal structure convenient for active force is taken so as to strengthen the resistance to capsizing of kingpost, while strengthens lifting
The stability of machine complete machine.
As one embodiment, in of the invention, the reinforcement of conical round table formula as shown in Figure 7 may be employed in the pedestal 1
Structure presets circular through hole in the pedestal 1 of conical round table formula, and the bottom of kingpost 3 is welded or on ocean platform,
Then by the through hole in pedestal 1, and welded with pedestal 1, to strengthen kingpost force stability, pedestal 1 is welded with ocean platform
It connects or is mounted on ocean platform with not welding.
As further embodiment, in of the invention, the pedestal 1 also uses the hollow reinforcement of cone-shaped as shown in Figure 8
Structure, the shape of pedestal 1 is cone-shaped, is welded into hollow shape pyramidal structure by stiffener plate, 3 bottom of kingpost is welded on base
The upper end of seat 1, the bottom of pedestal 1 is welded on ocean platform.
Structure design is simple in the present invention, easy for installation, maintenanceability is strong, improves vibrative mechanism in severe work
The reliability used under condition.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications also should
It is considered as protection scope of the present invention.
