Description
Technical field
The present invention relates to screw shaft of ship mounting technique fields, and in particular to a kind of rolling stock for screw shaft of ship installation
Component.
Background technique
The stern pipe of large-scale bulk freighter is usually single-bearing design, is installed to the construction stage of stern pipe in stern tube shaft, conventional does
Method is slowly carried out using the artificial method for drawing cucurbit lifting, and since stern tube shaft self weight is heavier, the method is not only time-consuming, laborious, and
Stern tube shaft is easy the play inside stern pipe, the easily babbit of damage stern tube bearing and inner wall arrangement in cucurbit drawing process
Stern sealing oil pipe, temp probe protection pipe, once damage can not also find in time, great quality is brought to construction in later period
Hidden danger.
Summary of the invention
To solve the above-mentioned problems, the present invention proposes a kind of rolling stock component for screw shaft of ship installation, it is intended to real
The axial steady rolling of existing stern tube shaft during installation, so that the axial steady displacement of stern tube shaft, it is ensured that stern tube shaft installation is gone on smoothly.Tool
The technical solution of body is as follows:
A kind of rolling stock component for screw shaft of ship installation, including horizontally disposed bottom plate, setting are in the bottom plate
On and according to a pair of of hold-down support that left and right directions is arranged, be respectively arranged with horizontal pin on a pair of of hold-down support
Axis, and its axis of pin shaft described in two is that front-rear direction is arranged and is parallel to each other, on described two pin shafts respectively rotationally
It is connected with movable bearing support, the top on the movable bearing support positioned at the pin shaft is provided with idler wheel, and the axis of the idler wheel
For left and right directions setting；The bottom plane of the movable bearing support is higher than the upper surface of the bottom plate, and the movable bearing support is around institute
Pin shaft is stated to rotate clockwise or counterclockwise and topple over one end end of its bottom plane after certain angle against the upper of the bottom plate
End face.
Preferably, the idler wheel is rotatably supported on the movable bearing support by roller shaft.
In above-mentioned technical proposal, by the way that movable bearing support is rotatably arranged on a pair of of hold-down support, set on movable bearing support
Idler wheel is set, the axial steady rolling of stern tube shaft during installation is realized, enables stern tube shaft in axial steady displacement, so as to true
Protect going on smoothly for stern tube shaft installation.
On the other hand, since movable bearing support can inwardly topple over (holding state) or pour out (non-supported state),
The initial stage of stern tube shaft lifting can allow movable bearing support to be in and pour out state, to reserve biggish space, lift to stern tube shaft
Later period allow movable bearing support to be in inside tilt state again, to realize positioning of the stern tube shaft on idler wheel, so as to increase roll
The safety and flexibility that carriage assembly uses.
In addition, using the switching of movable bearing support inwardly toppled over or poured out, can be carried out in stern tube shaft installation process
Stern tube shaft center whether confirmation in place.
One of as a preferred solution of the present invention, the idler wheel is the barrel-type roller that idler wheel surface has convex globoidal.
By setting the barrel-type roller that idler wheel surface has convex globoidal for idler wheel, stern tube shaft can be improved in rolling stock component
On centralized positioning precision and stability.
As the further improvement to barrel-type roller, shape of the top cydariform face of the barrel-type roller on shaft section is
The center of circle of one section of convex circular arc, the circular arc is located on the axis of the pin shaft.
Since the center of circle of its circular arc of the top cydariform face of barrel-type roller is located on the axis of the pin shaft, barrel-type roller is followed
The circular arc in upper part cydariform face is tangent with the outside diameter of screw shaft of ship always when movable bearing support is rotated around pin shaft together, in this way may be used
So that stern tube shaft more can successfully pour out movable bearing support after movement in place so that barrel-type roller and stern tube shaft
It disengages, to facilitate subsequent further installation.
As a preferred solution of the present invention two, the dump angle range of the movable bearing support is ± 45 °.
It preferably, can be in the bottom plane and bottom plate of the movable bearing support in order to change the dump angle of movable bearing support
Between be provided with adjustment cushion block for adjusting the movable bearing support dump angle, to adapt to the support of different-diameter stern tube shaft.
