Embodiment Construction

[0016] The embodiments of the present invention will now be described in conjunction with the accompanying drawings, and the present invention is not limited to the following embodiments.

[0017] like Figure 1-Figure 3 As shown, a small boat automatic catch and release device includes an automatic catcher 1 installed on the small boat 19 and a blocking device 2 installed on the mother ship 20 .

[0018] The automatic catcher includes a housing 3, a lower rotation block 4, a stop block 5, a torsion spring 6, an upper rotation block 7, a mandrel 21, a return spring 8 and a traction rope 9, and the upper rotation block is connected to the housing by the torsion spring. The top is hinged, the inner side of the bottom of the down-rotating block is hinged with the bottom of the shell through the pin shaft, the mandrel is installed in the inner cavity of the bottom of the shell, the outer end passes through the shell and is connected with the traction rope, and the inner end is pro...

Abstract

The invention relates to an automatic catching and releasing device and method for a small boat. After the small boat rushes on a slideway of a mother ship at a certain speed, the moment of a triangular frame is caught, a tensioning oil cylinder piston rod of a blocking device passively retracts, the collision force of the small boat can be absorbed, through effective buffer, the speed of the small boat is decreased until the small boat stops, the blocking device pulls an oil cylinder for outputting pulling force, a steel wire rope is driven to pull the small boat to the placement position, and catching and taking-back are completed; when the small boat is released, the blocking device automatically releases a collection and release rope and takes back a tensioning rope, the small boat slides downwards to the catching position, a pulling rope of the automatic catching device is pulled, and the small boat is automatically unhooked for releasing. According to the device, the small boat can be automatically and quickly caught, buffered, taken back and released, the automation degree is high, and the adaptation range is wide.

Description

technical field [0001] The invention belongs to the technical field of water surface transportation, and in particular relates to a small boat automatic catch and release device and method. Background technique [0002] The mother ship that performs the task is generally equipped with 1 to 2 high-speed boats as working boats. The traditional small boat retractable devices—marine cranes, davits, etc., have a slow retraction operation (lifting method), which generally takes more than 20 minutes. And this hoisting method requires the personnel to board the boat by the gangway after the boat is released, and the safety is insufficient. At present, the stern slideway type small boat retracting device is provided with an inclined slideway at the mother ship stern. When receiving the boat, the small boat rushes up to the slideway of the mother ship at a certain speed, and at the same time, the hook operator stands on the mother ship and uses tools to hang the steel rope on the ho...
