Description

Mechanical detacher of offshore operation throwing equipment

Technical Field

The utility model belongs to the technical field of unhooking device equipment, concretely relates to marine operation dispensing device's mechanical unhooking device.

Background

At present, when special equipment needs to enter the sea, the special equipment can only be hoisted to the sea surface through a mechanical arm, then the special equipment is thrown into the sea to be manually unhooked so as to release the equipment, and due to the fact that the sea is diverse and unstable in sea conditions, the equipment shakes in the sea entering process and is impacted by sea waves, the danger coefficient of manually unhooking the equipment is high, the operation time is long, and the unhooking time is unstable.

In order to solve the defects of the prior art, people have long searched for and put forward various solutions. For example, the chinese patent document discloses a hanging automatic unhooking device for a marine test facility [202210715693.7], which comprises a main frame, a limiting structure, a rolling ring, a pull rope, a spring, a hanging ring hook, a swing stopping ring and a hanging ring, wherein the main frame is formed by welding, the swing stopping ring and the hanging ring are welded on the main frame, the risk of loosening of parts is reduced, the rolling ring can roll by passing through a cross shaft, one end of the spring is hung on the hook at the bottom of the limiting structure, the other end of the spring is hung on the hook at the lower part of the main body, the limiting block is tensioned downwards by the pulling force of the spring in a natural state, the hanging ring is limited by a limiting block hole to rotate, one end of the pull rope is tied and fixed on a movable buckle and pressed through the rolling ring, the other end of the pull rope is pulled by hands to be in a relaxed state, and the facility is hung on the hanging ring. When the operation equipment needs to enter the sea for release, the pull rope is pulled downwards by manpower, the limiting structure moves upwards along the main body, the hook ring moves out of the limiting hole, the hook ring rotates rapidly under the gravity of the equipment, and the equipment automatically unhooks from the hook ring.

The problem that existing sea entering equipment cannot automatically unhook is solved to a certain extent through the scheme, but the scheme still has a lot of defects, for example, the automatic unhooking device of the automatic unhooking device is not provided with a stable structure, so that the rope and the device can rotate due to the fact that the automatic unhooking device shakes on a ship, and unhooking efficiency is reduced.
