Abstract
The invention discloses a kind of marine shafting locking devices, including flange, ball screw nut, latch, rotating dog and pedestal, the ball screw nut is evenly arranged on the circumference of flange, and the latch is connected on pedestal by rotating dog, and the latch is equipped with the slot that can be inserted into ball screw nut.Marine shafting locking device of the present invention, structure is simple, and installation is simple, and easy to operate, manufacturing cost is low, the locking of shaft and unlocks convenient and efficient, and latch is fixed by latch, and latch is difficult to slide, and use reliability is good；No particular/special requirement is designed to Propulsion Systems, be not required to increase shafting flange diameter or is slotted in flange periphery, the locking of shaft is directly realized in the way of locking connection bolt, it is easy to operate easy-to-use.
Description
Technical field
The present invention relates to a kind of marine shafting locking devices.
Background technique
The Propulsion Systems of modern ships need to lock Propulsion Systems under certain operating conditions, prevent propeller rotational, especially
It is twin shafting ship, relatively mostly uses locking device, when a propeller is operating, another propeller is in water flow in order to prevent
It when the lower drive shafting rotation of effect or inspection and repair of ship, prevents propeller from rotating with wave, needs that locking dress is arranged in shafting
It sets, remain stationary shafting, to protect gear-box etc..
Current propeller shafting system locked shaft device needs radially at least to open a notch in shafting flange, leads to flange
Size increases, and since this locking device can only be installed below shafting in compact limited space, and needs continuous jiggering, adjusts
Notch and lower section latch segment on whole flange is to just, and therefore, operation is extremely inconvenient.
Summary of the invention
The object of the present invention is to provide a kind of structure is simple, cost of manufacture is cheap, marine shafting locking dress easy to use
It sets.
Present invention technical solution used for the above purpose is: a kind of marine shafting locking device, including flange,
Ball screw nut, latch, rotating dog and pedestal, the ball screw nut are evenly arranged on the circumference of flange, and the latch passes through rotation
It ships and resell on another market and is connected on pedestal, the latch is equipped with the slot that can be inserted into ball screw nut.
Corresponding pin hole is equipped with above the latch and pedestal.
The diameter of the slot is greater than the diameter of ball screw nut on flange.
The thickness of the latch is equal to ball screw nut head thickness.
After the pedestal and flange positioning, it is weldingly fixed on floor.
A kind of marine shafting locking device of the present invention, structure is simple, and installation is simple, and easy to operate, manufacturing cost is low, to axis
The locking of system and unlock convenient and efficient, and latch is fixed by latch, and latch is difficult to slide, use reliability
It is good；No particular/special requirement is designed to Propulsion Systems, be not required to increase shafting flange diameter or is slotted in flange periphery, lock is directly utilized
The mode for being close to connecting bolt realizes the locking of shaft, easy to operate easy-to-use.
Detailed description of the invention
Fig. 1 is a kind of marine shafting locking device locking operating condition main view of the present invention.
Fig. 2 is a kind of marine shafting locking device locking operating condition side view of the present invention.
Fig. 3 is a kind of main view of the non-locking operating condition of marine shafting locking device of the present invention.
In figure: 1, flange；2, ball screw nut；3, latch；4, latch；5, rotating dog；6, pedestal.
Specific embodiment
As shown in Figure 1 to Figure 3, marine shafting locking device, including flange 1, ball screw nut 2, latch 3,5 and of rotating dog
Pedestal 6, ball screw nut 2 are evenly arranged on the circumference of flange 1, and latch 3 is connected on pedestal 6 by rotating dog 5, on latch 3
The slot diameter of slot equipped with pluggable ball screw nut 2, latch 3 is equal to the diameter of bolt+4mm, and the thickness of latch is equal to
Bolt head thickness, latch are connect by rotating dog with pedestal, and latch can be rotated around rotating dog, and latch 4 is by latch
It fixes with pedestal, limitation latch rotation, after pedestal and the positioning of shafting flange, is weldingly fixed on floor, in use, the bottom of by
Seat 6 is adjusted to suitable position at a distance from flange 1, and seat board 6 is welded to the deck of boat, when lock shaft state, uniformly connects two on flange 1
Latch 3 is rotated to 1 direction of flange around rotating dog 5, rotates to suitable position with any two by the ball screw nut 2 of root system
Ball screw nut 2 lock, then will latch 4 be inserted into pin hole after tighten, when non-lock shaft state, latch 3 is deviated from around rotating dog 5
The rotation of 1 direction of flange, then tightened after latch 4 is inserted into pin hole.
