Abstract

The invention relates to a telescopic boat davit, which comprises a base (1), a pylon (2), a lifting device, a davit arm (4). The swinging base (1) is fixed on a boat body; a rotary disk which can do circular rotary motion is arranged in the swinging base (1) and fixed with the swinging base (1) with bolts; the pylon (2) is also fixed with the rotary disk with the bolts; the pylon (2) can do 360 degrees of circular rotary motion around a central line of the swinging base (1); the base which can do radial motion can drive the pylon and the davit arm to do circular rotary motion together, so that the range of application of the telescopic boat davit is expanded; and the lifting device which is fixedly connected with the pylon effectively reduces the occupied deck space, and the lifting device is matched with the davit arm driven by an oil cylinder, so that the complexity of operation is simplified, and a user and an operator can operate the device in a safe way to make the boat ascend or descend.

Description

Telescopic boat davit

Technical field

The present invention relates to a kind of davit device, relate in particular to a kind of telescopic boat davit, this davit device is arranged on the vessel flank, hangs relevant lifesaving/rescue craft.

Background technology

Conventional boat davit generally is arranged in the side of ship side, and such layout has taken between deck space when ship is in stand; Common after the improvement falls keel block and is arranged in the position that is higher than the deck far away, the bondsman can be relatively freely boat davit below by, though such improvement does not take between deck space, but such boat davit is furnished with independently jacking system usually, be winch or jacking equipment. this independent-lifting device, manual operation for convenience and satisfy code requirement all requires arranged stationary above deck. like this for convenience of personnel operation structural arrangement taken sizable between deck space.

The conventional scalable boat davit of trapped orbit formula, adopt high-order the layout, jacking system by one or one group of bracket arm firm be fixed on one or more hang ship drive arm radially innermost can axially extended extensible member on, this carriage can move in the groove of static fixedly extensible member. and this layout adopts the aggregate motion of jacking system and extensible member, simplified control operation, reduced the area that takies the deck ship. but such structure telescopic boom can only move along the rail groove direction of fixed static. just can not meet the demands for the occasion that standby ship requirement is arranged in the side

Above structure boat davit, to the operating of ship the time, control step is loaded down with trivial details, generally all needs to operate through the personnel of special training.

Summary of the invention

1, technical matters to be solved:

Complexity and the problem that takies too much deck at existing boat davit the invention provides a kind of compact conformation, and can enlarge the telescopic boat davit of boat davit operating range.

2, technical scheme:
