Large-tolerance capturing, locking and releasing mechanism of a floating platform

Abstract

The invention puts forward a large-tolerance capturing, locking and releasing mechanism of a floating platform. Four capturing heads are hinged to the upper portion of a capturing head connecting bodyof the mechanism. A ball body is arranged below the capturing head connecting body; the ball body is matched with a ball socket of the ball socket body below the ball body; the periphery of the capturing head connecting body and the periphery of the ball socket body are sleeved with pose retaining springs; an ejector rod is arranged in the capturing head connecting body; a slideway is arranged inthe capture head connecting body; the ejector rod is located below the capturing head and moves up and down along the slideway; a micro motor is connected to the slideway of the capturing head connecting body and drives the ejector rod to move upwards through the lead screw; the small-diameter portion of the lower end of the ball socket body is sleeved with a disc spring assembly; a sleeve is installed outside the disc spring assembly; and a power source structure is installed outside the sleeve. The problem that a locking and releasing mechanism cannot complete unmanned automatic capturing and locking and releasing, has no installation error adaptive capacity and is not reliable in locking is solved, and the mechanism has a certain range of installation error adaptive capacity, is reliable in locking and has reliable force load maintaining capacity in the whole locking process.

Description

technical field [0001] The invention relates to a large-tolerance capture, lock and release mechanism for a floating platform, which belongs to the technical field of capture, lock and release of large-scale heavy-duty floating platforms. Background technique [0002] In the process of repeated installation and disassembly of large offshore platforms represented by large offshore floating platforms, there is a possibility of overturning due to force loads such as sea wind. big security risk. The large-scale assembly and adjustment equipment represented by the large-scale tooling platform of the factory is hoisted from other places to the designated large-scale installation plane, and there are also relatively large safety hazards in the process of capturing and locking it. Therefore, it is necessary to design an unattended automatic capture and lock-release mechanism for the special requirements of the installation process of these heavy-duty platforms. Reliable load holdi...

AI Technical Summary

Problems solved by technology

[0003] The present invention solves the problem that the unattended automatic capture and lock-release cannot be completed in the installation process of the heavy-duty platform in the prior art, and the tightening release mechanism has no ability to adapt to installation errors and the locking is unreliable, and provides a large tolerance Capture, lock and release mechanism, which can repeatedly capture, lock and release large heavy-duty platforms, and realize automatic capture, lock and release of floating platforms with certain rotation and translation errors that are located on large stationary platforms , to reduce the risk of manual operation, thereby resisting disturbances such as external wind loads, and avoiding the floating platform from tipping over during the working process
