Abstract
This utility model relates to a kind of pillar ocean platform crane Slewing Support Mechanism, is applied to sea work equipment manufacture industry.Main by including through type forced filling oil cup (1), upper strata journal bearing (2), lower floor's journal bearing (3), thrust bearing ring for fixing (4), thrust bearing (5), journal bearing limited block (6).This mechanism uses the mounting means of journal bearing and thrust bearing combination; utilize the bearing capacity advantage strong, corrosion resistant of MGB material; meet platform crane and should undertake the deadweight of revolution door frame, undertake various combined loads and the complex working condition of marine high salt fog during work again.Mechanism's bearing capacity good, failure rate is low strong, structural, easy to maintenance, with low cost, well solve platform crane rotation supporting device to take up room the problems such as big, perishable, inconvenient maintenance, greatly add the security reliability of crane, improve the work efficiency of crane, reduce the cost of batch production.
Description
Technical field
The invention belongs to sea work equipment manufacture industry.
Background technology
The in-depth utilized petrol resources exploitation along with the mankind and minimizing by land, oil-gas exploration and development is gradually proceeded to ocean by land so that ocean platform has welcome the spring of development.Ocean platform crane is mainly the crane used on ocean platform, is a kind of ocean platform handling goods and lifting people to the equipment above platform, is one of most important safety and production equipment during offshore oil produces.Its security reliability, maintainability, can wind resistance and corrosion resistance require the highest.The version that pillar ocean platform crane Shi Ge ocean platform manufacturing firm favors the most at present, this structure is visited frame mechanism and lower turntable mechanism forms by an independent fixing center pillar with rotatable, and it has safety good, the advantage such as load is big, speed is fast, efficiency is high, easy to maintenance, wind loading rating is strong high, structural.
Structurally and functionally saying, revolution position is one of the most key position of platform crane, and it had both undertaken the deadweight of revolution door frame, and had undertaken again various combined loads during lifting, and can the slew gear crane that is directly connected to whether reasonable in design run safely and reliably.At present, the form of domestic commonly used roller bearing, under equal bearing capacity, this form raceway diameter is the biggest, easily corrodes in the environment of need to taking large area space, and the highest salt fog, if bearing damage, need to dismantle door frame and related part integral lifting thereof.So, need a kind of bearing capacity good, failure rate is low, Slewing Support Mechanism easy to maintenance strong, structural badly.
Summary of the invention
This utility model is used for solving ocean platform crane Slewing Support Mechanism and takes up room the problems such as big, perishable, inconvenient maintenance, is a kind of bearing capacity good, failure rate is low, version easy to maintenance strong, structural.This mechanism uses the mounting means of journal bearing and thrust bearing combination; utilize the bearing capacity advantage strong, corrosion resistant of MGB material; meet platform crane and should undertake the deadweight of revolution door frame, undertake various combined loads and the complex working condition of marine high salt fog during work again.
This supporting device simple in construction, easily operated, structure is shown in accompanying drawing, mainly includes through type forced filling oil cup (1), upper strata journal bearing (2), lower floor's journal bearing (3), thrust bearing ring for fixing (4), thrust bearing (5), journal bearing limited block (6).Thrust bearing (5) is formed by four pieces of duplicate MGB material right angle sliding bearing docking, between intermediate cylinder supporting seat board and revolution door frame base plate, for undertaking the deadweight of revolution door frame and reducing the friction between itself and intermediate cylinder supporting seat board；Thrust bearing ring for fixing (4) is welded on revolution door frame, is used for fixing thrust bearing (5), and drives it to rotate together with revolution door frame when rotated；Upper strata journal bearing (2) and lower floor's journal bearing (3) are docked by 1/4 annulus of four blocks of duplicate MGB materials and form, for undertaking various combined load and reducing the friction between intermediate cylinder and revolution door frame；Journal bearing limited block (6) is welded on revolution door frame, the installation of journal bearing the most for convenience, on the other hand drives journal bearing to rotate together with revolution door frame；Four through type forced filling oil cups (1) are respectively arranged on upper strata journal bearing (2), for the injection of pivoting support grease；For ensureing good lubricant effect, upper strata journal bearing (2) and lower floor's journal bearing (3) inner ring all have the groove of intercommunication, while lubrication journal bearing, also can guarantee that thrust bearing (5) has enough lubrications.
Accompanying drawing explanation
The utility model is described in more detail with detailed description of the invention below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of Slewing Support Mechanism of the present invention, and Fig. 2 is the A-A profile of Fig. 1, and Fig. 3 is the B-B profile of Fig. 1, and Fig. 4 is detail drawing at C.
Detailed description of the invention
As it is shown in figure 1, the structural representation of Slewing Support Mechanism, in platform crane integral installation timing, on intermediate cylinder supporting seat board, mark the position line of thrust bearing (5), then by line-transect by thrust bearing (5) to connecting, and fix by corresponding frock；Door frame integral hoisting will be turned round, be positioned on thrust bearing (5), it is ensured that thrust bearing ring for fixing (4) is completely nested thrust bearing (5)；Turn round door frame with crane righting, four splits the most radially bearing limited block (6) of lower floor's journal bearing (3) is loaded the space between revolution door frame and intermediate cylinder；Four through type forced filling oil cups (1) are good with four separable assembleds of upper strata journal bearing (2) respectively, the upper part same manner assembled is loaded the space between revolution door frame and intermediate cylinder.Owing to each bearing inner race outer ring is matched in clearance, so whole process need not heating, install very convenient, also eliminate the cost brought because of heating.
This pillar ocean platform crane Slewing Support Mechanism design is complete, and receives the consistent accreditation of expert group of company.This version has been successfully applied to the 50T pillar ocean platform crane that Liaoning Luhai Petroleum Equipment Institute Co., Ltd. produces, easy for installation, and working effect is good, is greatly improved the work efficiency of crane.
It is understandable that, above with respect to the specific descriptions that the present invention is novel, be merely to illustrate the present invention novel and first with the technical scheme described by new embodiment of the present invention, it will be understood by those within the art that, still can modify or equivalent to the present invention is novel, reach identical technique effect；As long as meeting invention needs, all within the protection domain that the present invention is novel.
