Description
Technical field
The present invention relates to a kind of propeller sealing devices, belong to technical field of ship allocation.
Background technique
Propeller sealing is the operation to be carried out when ship is lauched using longitudinal inclined building berth, is that propeller turns in order to prevent
A kind of dynamic method for causing serious consequence is usually the blade progress binding and fixing to propeller in slipway launching at present, and
Difficulty of construction is big for binding and fixing, and safety coefficient is low, or directly propeller is allowed to be freely rotated, and without sealing measure, is allowed to
It freely rotates backward, may result in propeller and fall off.In order to solve the above difficulties, it is high to need to develop a safety coefficient, protects
Protect a kind of propeller sealing device of propeller.
Summary of the invention
The object of the present invention is to provide a kind of propeller sealing devices.
What is used when the problem to be solved in the present invention is current slipway launching carries out binding and fixing to propeller or allows spiral shell
Rotation paddle, which is freely rotated all, has that safety coefficient is low.
To achieve the purpose of the present invention, the technical solution adopted by the present invention is that:
A kind of propeller sealing device, including jackshaft, screw, perform, bolt, stern tube shaft flange, stern tube shaft, column, support rod, machine
Cabin rib cage, outer bracket, inner bottom plating, middle-grade and inner bracket, the intermediate shaft rear end install stern tube shaft, the interconnecting piece of stern tube shaft and jackshaft
Position installation stern tube shaft flange, stern tube shaft flange are mounted on the rear side that performs with bolt, and the left and right sides of stern tube shaft flange is screwed respectively
It in the rear side of column, performs and is mounted on column, column is mounted on inner bottom plating, and support rod, support rod are respectively installed in column side
It is mounted on cabin rib cage side, cabin rib cage is mounted on inner bottom plating, installs outer bracket between support rod and column, middle-grade and is stood
Inner bracket is installed between column.
The outer bracket is triangular structure.
The inner bracket is triangular structure.
The column is located at the left and right sides of jackshaft.
The invention has the advantages that the axis of propeller is locked in by the axis of jackshaft and stern tube shaft as propeller, stern tube shaft flange
In column, support rod, the space constituted with middle-grade of performing, sealing operation is carried out, propeller is rotated backward will not, avoids spiral
Paddle falls off, and safety coefficient is high, can protect propeller.
Detailed description of the invention
Fig. 1 is a kind of propeller sealing device overall structure main view of the present invention；
Fig. 2 is a kind of integrally-built stereoscopic schematic diagram of propeller sealing device of the present invention；
Fig. 3 is the side view of stern tube shaft flange；
In figure: 1, jackshaft 2, screw 3, the 4, bolt 5 that performs, stern tube shaft flange 6, stern tube shaft 7, column 8, support rod 9, machine
Cabin rib cage 10, outer bracket 11, inner bottom plating 12, middle-grade 13, inner bracket.
Specific embodiment
The present invention is further illustrated with reference to the accompanying drawings and embodiments.
A kind of propeller sealing device of the present invention, including jackshaft 1, screw 2, the 3, bolt 4 that performs, 6 flange 5 of stern tube shaft, stern
Axis 6, column 7, support rod 8, cabin rib cage 9, outer bracket 10, inner bottom plating 11, middle-grade 12 and inner bracket 13, after the jackshaft 1
The connecting portion of end installation stern tube shaft 6, stern tube shaft 6 and jackshaft 1 installs 6 flange 5 of stern tube shaft, and 6 flange 5 of stern tube shaft is mounted on bolt 4
3 rear side of shelves, the left and right sides of 6 flange 5 of stern tube shaft is fixed on the rear side of column 7 with screw 2 respectively, and performing 3 is mounted on column 7,
Column 7 is mounted on inner bottom plating 11, and support rod 8 is respectively installed in 7 side of column, and support rod 8 is mounted on 9 side of cabin rib cage, cabin
Rib cage 9 is mounted on inner bottom plating 11, and outer bracket 10 is installed between support rod 8 and column 7, between middle-grade 12 and column 7 in installation
Bracket 13.
The outer bracket 10 is triangular structure.
The inner bracket 13 is triangular structure.
The column 7 is located at the left and right sides of jackshaft 1.
Application method of the present invention: the axis of jackshaft 1 and stern tube shaft 6 as propeller, 6 flange 5 of stern tube shaft is by the axle envelope of propeller
Gu column 7, support rod 8, perform 3 and middle-grade 12 constitute space in, carry out sealing operation, turn propeller will not reversely
It is dynamic, falling off for propeller is avoided, safety coefficient is high, can protect propeller.
