Embodiment Construction

[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0031] figure 1 The dotted line in indicates that a plurality of spare boats can be arranged along the telescoping direction of the oil cylinder and the boom in the direction indicated by the arrow.

[0032] figure 2 The middle solid line represents the position for storing the boat, and the dotted line represents the launching position of the boat.

[0033] Such as figure 1 , figure 2 As shown, the retractable davit includes a base 1, a tower 2, a lifting device, and a davit jib 4; the lifting device includes a motor-driven lifting winch 3, and the motor-driven lifting winch can use Zhenjiang Weisite marine equipment The D30S / Z type hoisting winch produced by Co., Ltd., and the related single hoisting wire rope 6.

[0034] One end of this hoisting wire rope 6 is fixed in the hoisting winch reel barrel, and the other end passes through the support of a...

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

technical field [0001] The invention relates to a davit device, in particular to a telescopic davit device, which is arranged on the side wings of a boat mooring and suspends relevant life / rescue boats. Background technique [0002] Conventional davits are generally arranged on the side of the ship’s side. Such an arrangement takes up space on the deck when the boat is in a parked position; the improved ordinary davits are arranged far above the deck to ensure that people can hang on the boat relatively freely. The davit passes under the davit. Although such an improvement does not take up deck space, this type of davit is usually equipped with an independent lifting device, that is, a winch or a lifting device. This independent lifting device, in order to facilitate manual operation and meet the specification requirements , are required to be statically arranged on the deck. Such a structural arrangement for the convenience of personnel operation takes up a considerable amo...
