The movable capping apparatus of hydraulic cylinder driving
Technical field
Field of ship equipment is the utility model is related to, it is more particularly to a kind of to be suitable for and the matching used hydraulic pressure of lateral thruster
The movable capping apparatus of hydraulic oil cylinder driving.
Background technology
In the prior art, movable capping apparatus is generally realized the opening of capping plate using both following modes, is closed.
First, movable capping apparatus is realized the opening of capping plate, is closed using swing hydraulic pressure cylinder driving rotation axis;Its shortcoming
It is as follows:
First, swing hydraulic pressure cylinder directly drives the structure of rotation axis, oscillating cylinder is installed close to Inner wall of ship body, because of oscillating cylinder outside
Shape size is larger, linearly consistent with hull after plate is closed to ensure to cover, and causes to cover plate and rotation axle base is big, covered
After full opening, the water side of capping plate, rotation axis and its join domain is larger, causes larger resistance to water-flow and resistance power
Square, influences the performance of corollary equipment, is also easy to produce larger vibration.
Second, by universal shaft, swing hydraulic pressure cylinder drives the structure of rotation axis, and the installation site of oscillating cylinder can be slightly away from
Inner wall of ship body, but the addition of universal shaft, make structure slightly complicated, cost increase.
Third, it is swing hydraulic pressure cylinder price, complicated, cause capping apparatus holistic cost higher.
2nd, movable capping apparatus is realized the opening of capping plate, is closed using screw body driving rotation axis;Its shortcoming is such as
Under:
First, screw body overall volume is very big, limited by self structure, after capping is closed, cover plate shape and hull
Linear difference is very big, can not accomplish to reduce the purpose of ship resistance and noise.
It is higher to requirement on machining accuracy second, screw body is integrally complex, cause capping apparatus holistic cost compared with
It is high.
For ship, overall structure needs simple, reliable movable capping apparatus first, can smoothly realize beating for capping plate
Open and close are closed;Secondly after capping plate is opened, it is impossible to have a negative impact to corollary equipment performance, such as:If after covering plate opening,
If water side is very big, side thrust can be reduced, increase resistance torque and produce vibration;After covering plate closing, the outer of plate is covered
Shape should be consistent substantially with hull lines, to realize the purpose for reducing ship resistance and noise, meet that ship drag reduction drops
The basic requirement and special shipborne equipment offside made an uproar push away the particular/special requirement of the bubble of generation, vibration noise etc.;It is in addition, living
The design of dynamic capping apparatus should facilitate Field adjustment, general all some deviations of hull manufacture, and capping plate swing angle should can root
It is adjusted according to on-site actual situations;And the holistic cost of capping apparatus should be controlled, improve the economy of ship.
