Abstract

The invention belongs to the technical field of ship equipment, and particularly relates to rescue boat collecting and releasing equipment which comprises hanging brackets, winch mechanisms and hydraulic telescopic mechanisms which are symmetrically arranged, the hanging brackets are arranged on a deck, the hydraulic telescopic mechanisms are fixedly installed on the deck, the hanging brackets are provided with supporting beams, the front ends of the hanging brackets are connected with lifting beams, and the rear ends of the hanging brackets are connected with winch frames. The winch mechanism comprises a winch and a control box, the hoisting beam and the connecting beam are both provided with fixed pulleys, the winch is connected with a steel cable, the steel cable is provided with a hook, the hook is provided with a positioning cylinder, the steel cable penetrates through the positioning cylinder in a sleeving mode, and a connecting rod is connected between the positioning cylinder and the hoisting beam. The hydraulic telescopic mechanism is in transmission connection with the hoisting beam; by arranging the positioning cylinder and the connecting rod, the steel cable between the positioning cylinder above the hook and the hoisting beam cannot shake, and the safety and stability of the rescue boat in the releasing and retracting process are improved.

Description

technical field [0001] The invention belongs to the technical field of marine equipment, and in particular relates to a rescue boat retractable device. Background technique [0002] The rescue boat is a commonly used water rescue search and rescue boat. The rescue boat is usually placed on the deck. When it needs to be used, the rescue boat is put into the water through the retractable equipment. The retractable structure of the commonly used retractable equipment includes: There are hoisting structures and dock-type structures. The hoisting structure usually lifts the rescue boat above the higher deck through the hoisting arm. When releasing, the rescue boat can be moved to the deck by turning down the outside of the deck through the hoisting arm. On the outside, the hoisting structure usually needs to occupy a higher height space, while the dock-type structure usually hoists the rescue boat on the lower upper side of the deck through the hoisting arm. The rescue boat move...
