High-speed rescue boat lowering device

Abstract

The invention discloses a high-speed rescue boat lowering device. The device comprises a lifting arm frame, a lifting arm, pulling cables, a plurality of guide wheels, a first connecting part, a second connecting part and a hook, wherein the lifting arm is hinged with the lifting arm frame; the guide wheels are hinged to the lifting arm frame; the first connecting part is fixedly arranged on the lower end part of the lifting arm; the second connecting part is used for being connected with a rescue boat; the hook is fixedly arranged on the second connecting part; the first connecting part is provided with an inner cavity; the second connecting part is matched with the inner cavity; clamping grooves which are opened downwards are formed in the first connecting part; positioning rods are fixedly arranged on the second connecting part; the positioning rods are matched with the clamping grooves; an adjusting mechanism is arranged between the lifting arm frame and the lifting arm; the lifting arm frame and the lifting arm are matched through the first connecting part on the lifting arm and the second connecting part on the rescue boat; and the first connecting part and the second connecting part are matched through the clamping grooves and the positioning rods to form a rigid body. Swing is reduced in a rescue boat lowering process and a wave compensation effect can be achieved when the rescue boat falls onto the water surface, the rescue boat stably falls onto the water surface, the safety factor is high, and the stability is further improved because the adjusting mechanism for adjusting the verticality and the levelness is arranged.

Description

technical field [0001] The invention relates to a high-speed rescue boat launching device. Background technique [0002] Rescue boats are usually used as an escape tool for the crew when large ships are in distress. At present, most rescue boat launching devices include a boom frame, a boom hinged with the boom frame, a retractable device, and a The traction cable on the retractable device and the several guide wheels arranged on the boom frame, the traction cable is connected between the several guide wheels and the hook on the rescue boat , the above structure has the following disadvantages: 1. In the process of landing, due to the insufficient rigidity of the tow rope, the rescue boat will sway or even rotate during the landing process, causing the distressed people to be bumped again; 2. When the boat falls to the water surface, the rescue boat will heave up and down with the waves, the stability is poor, and it may cause secondary injuries to the victims, and the safe...
