Specific embodiment
Below, in conjunction with example, the substantive distinguishing features of the present invention and advantage are further described, but the present invention not office
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, use
The turntable 2 that is connected in arm support 12, kingpost 3, door frame 4, for preventing longitudinal leap-preventing device of door frame longitudinal leap；Wherein,
The top of turntable 2 is connected by four bearing pins 21 with the bottom of door frame 4, 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 living
The lower bearing component for configuring at dynamic cooperation, upper shaft bearing assembly can achieve to realize 360 degree of revolutions around kingpost 3, and lower bearing component is pacified
It is mounted at the clearance fit between turntable and kingpost, upper shaft bearing assembly 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, and wherein, upper support pipe 6 is solid by welding
The top of kingpost 3 is scheduled on, the bearing pin 5 that is fixed by bolt 7 is installed on upper support pipe 6, to act the work for reaching longitudinal anti-channeling
With.
Specifically, the upper end of the kingpost 3 has installing hole, installing hole described in 6 partial insertion of upper support pipe
In after, with the kingpost 3 by being welded to connect fixation, the bearing pin 5 is opened up installed in the radial direction of the upper support pipe 6
In pin shaft hole, and locked by bolt 7 in two close end, prevent from coming off, as shown in figure 3, the upper shaft bearing assembly 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 strata footpath
To the upper-end contact of 8, MGB of bearing lower floor, 9, MGB of journal bearing upper strata journal bearing, 8 lower end and MGB lower floor 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 bearing 10 is enclosed within MGB lower floor
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 plastic
Material alloy) lower floor's journal bearing 9, MGB (engineering plastic alloy) thrust bearing 10, by the upper shaft bearing assembly, the door frame 4
Can be turned round around the upper support pipe 6.
The turntable 2 connects arm support 12 by bearing pin, is provided with MGB (engineering plastic alloy) between kingpost 3 and turntable 2
Sliding bearing 11, used as lower bearing component, as shown in figure 4, passing through the lower bearing component, 360 degree of revolutions realized by turntable 2, and upper
Bearing assembly together, is realized axis 360 degree of the turntable with door frame around the kingpost and 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 be tightly fitted 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 together and is acted on ocean platform afterwards, in order to increase crane resistance to capsizing,
In the present invention, the main body of the kingpost 3 is the cylindrical portion for being connected by cylindrical structure of pyramidal structure, bottom and pedestal 1,
As pedestal 1 adopts taper structure, after being connected with cylindrical portion, be so gradually increased the sectional area of primary structure member, beneficial to rise
In heavy-duty machine work, suffered load is improve the overturn-preventing ability of crane loading process and stablizes to the transmission of place platform
Property.
The cylindrical portion of the cylindrical structure of the kingpost, can adopt steel plate welding forming, the company of the cylindrical structure
The cylindrical portion for connecing can make kingpost stress steadily, reduce impulsive force suffered by emergency situations, be effectively improved crane
Overturn-preventing ability.And pedestal adopts taper structure, the sectional area of primary structure member is gradually increased, beneficial to institute in crane work
The load that receives is transmitted to place platform, improves overturn-preventing ability and the 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 delivered to metal (upper component, and metal (upper component is not subject to tilting moment substantially, and tilting moment is mainly by general
Army's post 3 bears, and contrasts the square column pier that land crane is adopted, as arm support revolution can cause lifting motor spindle institute
There is large change so as to produce impact in the tilting moment that receives, and in the present invention, as kingpost 3 is using the company of cylindrical structure
Socket part is connected with the pedestal of cone-shaped, and as arm support is turned round, the tilting moment size suffered by 3 bottom of kingpost has no larger
Change, can effectively optimize overturn-preventing ability using the connecting portion of cylindrical structure；While the pedestal 1 of cone-shaped is inclined by identical
When covering torque, pyramidal structure is taken to be easy to the transmission of active force so as to strengthen the resistance to capsizing of kingpost, while strengthening lifting
The stability of the whole machine of machine.
As one embodiment, in the present invention, the pedestal 1 can adopt the reinforcement of conical round table formula as shown in Figure 7
Structure, presets manhole in the pedestal 1 of conical round table formula, the bottom welding of kingpost 3 or on the ocean platform,
Then by the through hole in pedestal 1, and weld with pedestal 1, to strengthen kingpost force stability, pedestal 1 and ocean platform weldering
It is arranged on ocean platform with connecing or do not weld.
As further embodiment, in the present invention, the pedestal 1 is also adopted by the hollow reinforcement of cone-shaped as shown in Figure 8
Structure, pedestal 1 be shaped as cone-shaped, hollow shape pyramidal structure is become by reinforcement plate weld, 3 bottom welding of kingpost is in base
The upper end of seat 1, the bottom welding of pedestal 1 is on ocean platform.
In the present invention, structure design is simple, easy for installation, maintainability is strong, improve vibrative mechanism in severe work
The reliability for using 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, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should
It is considered as protection scope of the present invention.
