Description
Technical field
The present invention relates to hoisting crane, relate in particular to a kind of rotating disc type rotary supporting device that is used for marine hoister in large tonnage ex hoc genus anne equipment.
Background technology
At present, the pivoting support of large rotary-disc rotary crane mainly contains two kinds of forms: load dividing dolly formula and many row's roller types.
Load dividing dolly formula rotary supporting device mainly adopts the wheel carrying that has equalizing bar, and wheel is stressed simple clear and definite, and wheel load is evenly distributed.But owing to hang when carrying impact is arranged, during big elevating capacity, center-of-gravity position is higher, and crane stability is poor, and wheel load is big, and bottom cylindrical shell concentrated load is big, and its load-carrying capacity is limited.
Mainly adopt the densely covered wheel carrying of many rows and arrange the roller type rotary supporting device more, compact conformation, center-of-gravity position is low, rotating part stability is high, make relative simple with installation, be tending towards evenly by adopting track predeformation and the mode that adds pad that wheel load is distributed, supporting cylinder is stressed more satisfactory.But the load difference of wheel is big, the structure waste, and from great, cost is higher, and when the hoisting capacity super large, because the bulk restriction, its load-carrying capacity still is apparent not enough.
Along with the hoisting crane development trend of large-scale, the load of the pivoting support that hoisting moment produces is increasing.Because the restriction of oad and load-carrying capacity, load dividing dolly formula and many row's roller type pivoting supports all can't satisfy the requirement of some ultra-large type rotary crane, must study the novel rotation supporting to solve the pivoting support problem of existing ultra-large type rotary crane.
Summary of the invention
Main purpose of the present invention is to overcome the above-mentioned shortcoming that prior art exists, and provide a kind of rotating disc type rotary supporting device, its compact conformation, in light weight, load-carrying capacity is big, has solved the problem of the load-carrying capacity deficiency of existing rotary supporting device on large-tonnage full circle swinging weight-lifting equipment; Simultaneously, its rotating part center-of-gravity position is low, has improved crane stability, and manufacturing is relative simple with installation, and use and easy to maintenance.
The objective of the invention is to realize by following technical scheme:
A kind of rotating disc type rotary supporting device is provided with pivoting support, it is characterized in that: this pivoting support comprises: vertical support and the anti-supporting two parts that roll; Wherein, vertical support comprises: be installed in first annular ledge and first annular slide track that is installed in hoisting crane pedestal top of turn table bottom, first bearing and first slideway constitute makes hoisting crane at the rotating sliding friction pair in pedestal top; Instead roll supporting and comprise: be installed in second annular ledge on the turn table lower support structure and be installed in second annular slide track of the bottom of hoisting crane pedestal top structure beam, this second bearing and second slideway constitute makes hoisting crane at the rotating sliding friction pair in pedestal top.
Described slideway is made by the high molecular abrasion-proof material; Slideway adopts piecemeal to make, and is affixed on the mounting seat by fastener, between the slideway piece block is installed.
Described block is the square-section.
Described vertical support and instead roll supporting and can make number row.
Beneficial effect of the present invention: the present invention is owing to adopt technique scheme, its compact conformation, in light weight, load-carrying capacity is big, has solved the problem of the load-carrying capacity deficiency of existing rotary supporting device on large-tonnage full circle swinging weight-lifting equipment; Simultaneously, because the carriage height dimension is little, its rotating part center-of-gravity position is low, has improved crane stability, and manufacturing is relative simple with installation, and use and easy to maintenance.Be applicable to marine hoister in large tonnage ex hoc genus anne equipment

The specific embodiment
As shown in Figure 1, the present invention includes: pivoting support 2, pivoting support 2 mainly by vertical support, counter roll the supporting form.Vertical support is mainly used in bears the vertical power that weight-lifting equipment deadweight and lifted load produce, and instead rolls supporting and is mainly used in and bears the vertical power that tilting moment produces.Pivoting support 2 is arranged between hoisting crane pedestal 3 and the turn table 1.
Vertical support mainly comprises: the ring stainless steel bearing 4 and annular slide track 5 two parts that are installed in hoisting crane pedestal 3 tops that are installed in turn table 1 bottom by bolted connection.Ring stainless steel bearing 4 is that the vertical power that weight-lifting equipment is conducted oneself with dignity and lifted load produces is delivered on the annular slide track 5 by plane contact, and ring stainless steel bearing 4 and slideway 5 constitute sliding friction pairs, and hoisting crane is turned round on pedestal 3 tops.Slideway 5 is made by the high molecular abrasion-proof material, and by the interpolation grease, and friction coefficient is less between the corrosion-resistant steel; And, owing to be the face contact, have enough compressive strength to bear vertical load, the pressure failure-free of superstructure can be passed to the basis; The shearing force that has shearing strength value preferably to produce between the friction face when satisfying crane rotation.
When the rotating part center of gravity of hoisting crane is beyond the circle that vertical support constitutes, can produce tilting moment.Tilting moment is born by counter rolling, instead roll supporting and mainly comprise: be installed in the ring stainless steel bearing 7 that stretches out from turn table 1 bottom on the supporting construction 8 by bolted connection, annular slide track 6 is installed in bottom at hoisting crane pedestal 3 top structure beams, corrosion-resistant steel bearing 7 is delivered to the upwards vertical power that tilting moment produces on the annular slide track 6 by plane contact, ring stainless steel bearing 7 and annular slide track 6 constitute makes hoisting crane at the rotating sliding friction pair in pedestal 3 tops, and hoisting crane is turned round on pedestal 3 tops.Annular slide track 6 is made by the high molecular abrasion-proof material, and by the interpolation grease, and friction coefficient is less between the corrosion-resistant steel; And, owing to be the face contact, have enough compressive strength to bear vertical load, anti-roll extrusion power failure-free can be passed to hoisting crane pedestal 3; The shearing force that has shearing strength value preferably to produce between the friction face when satisfying crane rotation.
Vertical support, the anti-magnitude of load that supports according to bearing that rolls can be made single, double or many rows, realize very big load-carrying capacity.
As shown in Figure 3, annular slide track 5,6 of the present invention is considered maintenance and is changed conveniently, the employing piecemeal is made, by bolt 11 several slideway pieces 9 are affixed on the mounting seat 10, square-section block 12 is installed between several slideway pieces 9, be used for carrying the shearing force that produces between the friction face, play the slideway fixation to guarantee 11 on bolt, and do not bear shearing load.
Advantage of the present invention:
1, the present invention is owing to adopt plane contact, significantly improves than the line contact or the some contact load-carrying capacity of wheel in the prior art.
2, the present invention is in light weight, makes installation and maintenance and all has significant advantage.
The above, it only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention all still belongs in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment did.
