A limit bracket device for an underwater platform lifting system

Abstract

The invention belongs to the technical field of underwater testing, and in particular relates to a limit support device of an underwater platform lifting system. The invention can prevent the underwater platform from shaking too much when it is lifted vertically out of the water or put into the water vertically from the air. The spring buffer device of the present invention adopts the design of a two-way spring, which can buffer the limit bracket in both directions. While reducing the left and right shaking of the platform device, it can also give the platform experimental device a certain buffer space to prevent the platform from being damaged during the platform installation process. The problems such as inability to position due to errors in the center reduce the risk of damage to the limit bracket device due to excessive external force, and the guide wheel will not be easily derailed by the action of spring force. The invention utilizes the guide wheel guide rail to achieve good position limiting and moving functions. When the guide wheel rolls on the angle steel track, it can effectively ensure that the hoisted experimental platform device will not shake back and forth, and when the lifting operation is performed in the pool, the heavy equipment Able to move straight vertically.

Description

Technical field [0001] The present invention belongs to the field of underwater test, and is specifically related to a limit bracket device for underwater platform lifting systems. Background technique [0002] The underwater test environment is special, and the equipment is in a state in which the real-time monitoring and artificial intervention is not in progress, and the equipment floating anti-rust storage, the equipment is suspended, and when the test device is regularly maintained and maintained, it involves frequent equipment. Savings from the water surface and put in water, therefore, the underwater test device has an elevation platform system extremely necessary. In order to ensure the predetermined structural strength and experimental requirements, the predetermined structure is large, and the precision facilities such as a large number of sensors are installed, which cost is high, which has a very high in the equipment. Require. [0003] The lifting of the underwater t...

AI Technical Summary

Problems solved by technology

[0003] The lifting of the underwater test device usually adopts the steel wire rope hoisting platform to realize the vertical water entry and exit action. While the multi-point wire rope hoisting platform realizes synchronous operation, it is not suitable to strictly restrict its movement through slide rails, otherwise, due to the shift of the center of gravity of the platform equipment The platform and track are stuck due to other reasons, which increases the failure rate of equipment and the difficulty of maintenance

However, when the equipment enters and exits the water, it will also sway due to the influence of buoyancy and water flow fluctuations. In order to ensure the normal operation of the equipment, the safety of the platform's moving and lifting process and the installation and positioning after falling into the water have high requirements.
