Small ship-borne foldable hoisting system

Abstract

The invention discloses a small ship-mounted foldable hoisting system, which comprises a hoisting mechanism and a folding box located in a ship body. A hoisting base, a pillar prop connecting base, amovable hoisting base holder and a mechanical arm holder are arranged in the folding box, the pillar prop connecting base, the movable hoisting base holder and the mechanical arm holder are sequentially located on one side of the hoisting base, and the hoisting base is articulated with fixed bases located at both ends of the hoisting base; the hoisting mechanism comprises a movable hoisting base which is connected to a pillar through a bearing; a winch-fixing plate with an electric winch is turnably mounted on one side of the pillar; a mechanical arm is articulated with the top end of the pillar, and the mechanical arm and a first electric cylinder are located on the same side of the pillar; pulleys are arranged at both ends of the mechanical arm, and after passing through the pulleys, a hoisting rope drawn out from the electric winch is fixed on the mechanical arm; a balancing plate which can move along the hoisting rope is sleeved on the hoisting rope, the balancing plate is connected to a fixed plate through fixing ropes, the bottom of the fixed plate is provided with an opening along the length of the balancing plate, and a hoisting hook which runs through the opening of the fixed plate is arranged in the fixed plate; the movable hoisting base is vertically fixed on the hoisting base, and a pillar prop is detachably arranged between the movable hoisting base and the foldingbox.

Description

technical field [0001] The invention belongs to the technical field of marine ships and relates to a small ship-borne foldable hoisting system. Background technique [0002] The lifting device is an important part of the marine operation of the ship. In order to facilitate the offshore operation, the existing commonly used marine lifting devices are generally installed and fixed on the ship's installation platform or stored in the factory near the wharf. The lifting device fixedly installed on the ship installation platform takes up a large space of the ship when not in use, which affects the effective use of the space of the ship. It is stored in a factory building near the wharf. When used, it needs to be transported to the wharf where the ship is berthing, and then assembled and fixed on the ship. It needs to be reinstalled every time it is used. After use, it needs to be disassembled and then sent to the factory building, which is extremely inconvenient to use. Therefor...
