Abstract
The utility model relates to a self -elevating drilling unit lifting pipe upset bracket technical field, in particular to ocean engineering is with lubricated articulated shaft. The device's articulated shaft body one end is opened has the oiling mouth, and the grease nipple is connected to the oiling mouth, and the inside axial design of articulated shaft body has the oiling main entrance, and the oiling main entrance is linked together with the oiling mouth, and the inside radial design of articulated shaft body has oiling branch road a plurality of and articulated shaft body outer wall intercommunication, and all oiling branch roads all are linked together with the oiling main entrance, and every oiling branch road outside exit end all is linked together with a feed -tank. The utility model discloses a simple convenient and fast of operation process to the articulated shaft carries out the lubrication saves a large amount of manpower and materials, and is lubricated effectual. Overcome the articulated shaft anticorrosive lubricated method complex operation of current lifting pipe upset bracket, work load is big, and lubricated effect is unsatisfactory not enough.
Description
Technical field：
The utility model is related to self-elevating drilling platform lifting pipe turning support technical field, more particularly to a kind of ocean work
Journey lubrication jointed shaft.
Background technology：
Lifting pipe turning support is usually located at self-elevating drilling platform and respectively encloses well, is under the jurisdiction of pre- ballast sea water service system, certainly
Lift-type drilling platforms carries out playing support immersible pump, lifting pipe in drilling operation course.Carrying out the complexity of drillng operation
In sea situation, natural environment high-temperature, high humility, salinity high, the hinge point without corrosion-inhibiting coating protection are highly prone to electrochemistry
Corrode and damage.The hinge point of corrosion is not only difficult with turning support, and prolonged electrochemical corrosion also can receive axle
Damage, reduce the modulus of section, influence the intensity of axle, or even cause axle fracture, immersible pump, lifting pipe fall damage, pre- ballast seawater
Systemic breakdown, platform dead electricity.Accordingly, it would be desirable to often carry out oiling lubricating maintenance to hinge point.Existing maintenance mode is hand
Work jointed shaft is lubricated grease smearing, this kind of method need under conditions of immersible pump, lifting pipe are sling by compressed air hoist incite somebody to action
The jointed shaft of turning support is carried out after removing, and process is cumbersome and workload is huge, and lubricant effect is not satisfactory.
Utility model content：
The technical problems to be solved in the utility model is to provide a kind of ocean engineering lubrication jointed shaft, the arrangement achieves
The operating process being lubricated to jointed shaft is simple and convenient quick, saves a large amount of manpower and materials, high lubricating effect.Overcome existing
Lifting pipe turning support jointed shaft anti-corrosion lubricating method it is cumbersome, workload is big, the undesirable deficiency of lubricant effect.
Technical solution adopted in the utility model is：A kind of ocean engineering lubrication jointed shaft, including it is hinged shaft body；
It is hinged shaft body one end and is provided with pouring orifice, pouring orifice connection grease nipple, jointed shaft body interior axial design has oiling main channel,
Oiling main channel is connected with pouring orifice, and jointed shaft body interior radial design has multiple notes connected with jointed shaft body outer wall
Oily branch road, all of oiling branch road is connected with oiling main channel, each oiling branch road outer outlets end with a fuel feeding
Groove is connected, and oil supply tank is the annular groove on jointed shaft body outer wall, and the position of oil supply tank is sleeved on for turning support otic placode
Position on jointed shaft body outer wall.
The a diameter of 4mm in oiling main channel.
The a diameter of 3mm of oiling branch road.
The a width of 5mm of oil supply tank, depth is 0.5mm.
The beneficial effects of the utility model are：It is simple that the utility model realizes the operating process being lubricated to jointed shaft
It is convenient and swift, save a large amount of manpower and materials, high lubricating effect.
Brief description of the drawings：
The utility model is described in more detail with reference to the accompanying drawings and detailed description.
Fig. 1 is structural representation of the present utility model.
Specific embodiment：
As shown in figure 1, a kind of ocean engineering lubrication jointed shaft, including it is hinged shaft body 1；The one end of shaft body 1 is hinged to open
There is pouring orifice 2, the connection grease nipple 6 of pouring orifice 2 is hinged the inside of shaft body 1 and is axially designed with oiling main channel 3, oiling main channel 3
It is connected with pouring orifice 2, is hinged the inner radial of shaft body 1 and is designed with multiple and is hinged the oiling branch road that the outer wall of shaft body 1 is connected
4, all of oiling branch road 4 is connected with oiling main channel 3, each outer outlets end of oiling branch road 4 with an oil supply tank 5
It is connected, oil supply tank 5 is to be hinged annular groove on the outer wall of shaft body 1, the position of oil supply tank 5 is sleeved on for turning support otic placode
It is hinged the position on the outer wall of shaft body 1.The a diameter of 4mm in oiling main channel 3.The a diameter of 3mm of oiling branch road 4.Oil supply tank 5 is a width of
5mm, depth is 0.5mm.
After the fuel feeding of grease nipple 6, lubricant grease enters each oil supply tank 5 along oiling main channel 3 through each oiling branch road 4, supplies
The lubricant grease of storage is persistently lubricated by axle and turning support otic placode gap to hinge point and anti-corrosion is protected in oil groove 5
Shield.
It is understood that above with respect to specific descriptions of the present utility model, be merely to illustrate the utility model and not
The technical scheme described by the utility model embodiment is limited to, it will be understood by those within the art that, still can be with
The utility model is modified or equivalent, to reach identical technique effect；As long as satisfaction uses needs, all in this reality
Within new protection domain.
