Orchid, the first weldment, the second weldment, described after-poppet bearing press mounting enter after-poppet bearing block, first seamless steel pipe one end
Weld a part as overall stern pipe, the other end and the welding of the second weldment with after-poppet bearing block, the second weldment it is another
Welded with fore-stock bearing block one end；
Fore-stock bearing press mounting enters fore-stock bearing block, and fore-stock bearing block is consolidated with hull using epoxy installation blending bolt
Due on hull；First sensor pipe passes through fore-stock bearing, then punches and penetrate on after-poppet bearing, during which sets multiple
Support is used as sensor tube support；One end of first weldment is welded with fore-stock bearing block, and the other end and the second seamless steel pipe weld
Connect；
Stern pipe fore bearing is pressed into stern pipe front-end bearing pedestal；PT100 temperature sensors load stern pipe fore bearing, and forward flange uses
Bolt is fixed on stern pipe front-end bearing pedestal, and is installed on together with stern pipe front-end bearing pedestal using epoxy on propeller boss.
The utility model has that structure composition is reasonable, good seal performance, can play good sealing effectiveness, so as to reduce profit
The features such as leakage of lubricating oil, significantly mitigation environmental pollution.
Brief description of the drawings
Fig. 1 is the stern tubular construction schematic diagram of prior art.
Embodiment
The utility model is described in detail below in conjunction with accompanying drawing：As shown in figure 1, one kind described in the utility model
For the stern tubular construction peculiar to vessel of oil lubrication, it mainly includes after-poppet bearing block 1, after-poppet bearing 2, first sensor pipe 3, biography
Sensor pipe holder 4, seamless steel pipe 5, fore-stock bearing block 6, fore-stock bearing 7, second sensor pipe 8, stern pipe front-end bearing pedestal 9,
Stern pipe fore bearing 10, PT100 temperature sensors 11, forward flange 12, the first weldment 13, the second weldment 14, it is characterised in that
Described after-poppet bearing 2 is pressed into after-poppet bearing block 1, and conduct is welded in the one end of the first seamless steel pipe 5 with after-poppet bearing block 1
A part for overall stern pipe, the other end weld with the second weldment 14 when mounted, the other end and the preceding branch of the second weldment 14
Frame bearing block 6 welds；
Fore-stock bearing 7 is pressed into fore-stock bearing block 6, and fore-stock bearing block 6 is installed using epoxy with hull and uses spiral shell
Bolt is fixed on hull；The sensor tube support 4 of first sensor pipe 3 as support and through after fore-stock bearing 7, in after-poppet
Punch and penetrate on bearing 2；One end of first weldment 13 is welded with fore-stock bearing block 6, the other end and the second seamless steel pipe 5
Welding；
Stern pipe fore bearing 10 is pressed into stern pipe front-end bearing pedestal 9；PT100 temperature sensors 11 load stern pipe fore bearing 10, preceding
Flange 12, which is adopted, to be bolted on stern pipe front-end bearing pedestal 9, and is installed on propeller boss using epoxy together with stern pipe front-end bearing pedestal 9
On.
Embodiment：The utility model is mainly used in 800 tonnes of marine environment investigation ships, and the ship includes adjustable propeller, shafting,
Hydraulic system, marine gearbox, axle generator, remote control system.The ship is the double oars of two-shipper.Main frame is XCW8200ZD-10 two
