Specific embodiment
Below, substantive distinguishing features of the present utility model and advantage are further described with reference to example, but this practicality is new
Type is not limited to listed embodiment.
As shown in figures 1 to 6, a kind of pedestal 1 of general's pillar ocean platform crane pedestal, including taper mesa-shaped structure, use
In turntable 2, kingpost 3, door frame 4, the 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 bottom of door frame 4 by four bearing pins 21, and turntable 2 is sleeved on general by default post holes 22
On post 3, the bottom 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
The lower bearing component of configuration, upper bearing (metal) component can be realized realizing 360 degree of revolutions, lower bearing component peace around kingpost 3 at dynamic cooperation
At movable cooperation between turntable and kingpost, upper bearing (metal) component is arranged between the top of door frame and kingpost, such as Fig. 2
Shown, longitudinal leap-preventing device is made up of bearing 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, the bearing pin 5 fixed by bolt 7 is installed on upper support pipe 6, the work of longitudinal anti-channeling is reached to rise
With.
Specifically, the upper end of the kingpost 3 has mounting hole, mounting hole described in the partial insertion of upper support pipe 6
In after, with the kingpost 3 by being welded to connect fixation, what the radial direction that the bearing pin 5 is arranged on the upper support pipe 6 was opened up
In pin shaft hole, and locked by bolt 7 in two close end, prevent from coming off, as shown in figure 3, the upper bearing (metal) component includes MGB
(engineering plastic alloy) thrust bearing 10, between the upper end of kingpost 3 and the corresponding lower surface of door frame 4, MGB upper stratas footpath
To bearing 8, MGB lower floors journal bearing 9, the upper-end contact of the lower end of MGB upper stratas journal bearing 8 and MGB lower floors journal bearing 9, two
Person is placed between door frame 4 and upper support pipe 6, is specially enclosed within outside upper support pipe 6, and MGB thrust bearings 10 are enclosed within 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 in supporting MGB (engineering plastic alloy) upper strata journal bearing 8, MGB (engineering plastics
Material alloy) lower floor's journal bearing 9, MGB (engineering plastic alloy) thrust bearing 10, by the upper bearing (metal) component, the door frame 4
Can be turned round around the upper support pipe 6.
The turntable 2 connects arm support 12 by bearing pin, and MGB (engineering plastic alloy) is provided between kingpost 3 and turntable 2
Sliding bearing 11, it is and upper as shown in figure 4, by the lower bearing component, turntable 2 realizes 360 degree of revolutions as lower bearing component
Bearing assembly together, realizes that axis 360 degree of the turntable with door frame around the kingpost is turned round.
When ocean platform crane is in bad working environments, longitudinal random wave force is delivered to pedestal by ship or platform
1, 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 the bearing pin 5 on device can tightly fit with the upper end formation of door frame 4, can effectively prevent turntable 2 and door frame 4 from occurring larger
Lengthwise 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 transmitted act on ocean platform together afterwards, in order to increase crane resistance to capsizing,
In the utility model, the main body of the kingpost 3 is the circle for being connected by cylindrical structure of pyramidal structure, bottom and pedestal 1
Post portion, because pedestal 1 uses taper structure, after being connected with cylindrical portion, so gradually increased the sectional area of primary structure member, profit
Suffered load improves the overturn-preventing ability of crane loading process and steady to the transmission of place platform in crane work
It is qualitative.
The cylindrical portion of the cylindrical structure of the kingpost, can use steel plate welding forming, the company of the cylindrical structure
The cylindrical portion for connecing can make that kingpost stress is steady, reduce impulsive force suffered by emergency situations, be effectively improved crane
Overturn-preventing ability.And pedestal uses taper structure, the sectional area of primary structure member is gradually increased, institute in being worked beneficial to crane
The load received is transmitted to place platform, improves the overturn-preventing ability and stability of crane loading process.
Due to vibrative mechanism in the lifting during, the power born by rope and arm support respectively with pulling force and
The form of pressure is delivered 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 post 3 bears, the square column pier that contrast land crane is used, as arm support revolution can cause lifting motor spindle institute
There is large change so as to produce impact in the tilting moment received, and in the utility model, because kingpost 3 uses cylindrical structure
Connecting portion be connected with the pedestal of cone-shaped, as arm support is turned round, the tilting moment size suffered by the bottom of kingpost 3 has no
Large change, the connecting portion using cylindrical structure can effectively optimize overturn-preventing ability；The pedestal 1 of cone-shaped is subject to identical simultaneously
Tilting moment when, take pyramidal structure to be easy to the transmission of active force so as to strengthen the resistance to capsizing of kingpost, while strengthening
The stability of the whole machine of crane.
Used as one embodiment, in the utility model, the pedestal 1 can be using conical round table formula as shown in Figure 7
Reinforcement structure, presets manhole, the bottom welding of kingpost 3 or flat installed in ocean in the pedestal 1 of conical round table formula
On platform, then by the through hole in pedestal 1, and welded with pedestal 1, to strengthen kingpost force stability, pedestal 1 is put down with ocean
Platform is welded or is not arranged on ocean platform with not welding.
Used as further embodiment, in the utility model, the pedestal 1 is also adopted by the hollow of cone-shaped as shown in Figure 8
Reinforced structure, pedestal 1 is shaped as cone-shaped, by reinforcement plate weld into hollow shape pyramidal structure, the bottom welding of kingpost 3
In the upper end of pedestal 1, the bottom welding of pedestal 1 is on ocean platform.
Structure design is simple, easy for installation in the utility model, maintenanceability is strong, improve vibrative mechanism is disliking
The reliability used under bad operating mode.
The above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improve and
Retouching also should be regarded as protection domain of the present utility model.
