Marine suspension ring load testing device

Abstract

The invention discloses a marine suspension ring load testing device which comprises a supporting shaft, an inner framework, an outer framework and a jack, wherein the inner framework is sheathed outside a testing suspension ring, the outer framework is sheathed outside the inner framework, and the supporting shaft penetrates through a pin hole among the suspension ring, the inner framework and the outer framework; the jack is arranged between the bottom of the inner framework and the bottom of the outer framework; and in testing, the top of the inner framework is in contact with a ship body. The device disclosed by the invention has obvious convenience, safety and economy advantages, is portable and simple, and can be carried by one person to two persons; tons of weights are not needed to be carried; the device is convenient to install and test, and safe and reliable by simulating tons of or even hundreds of tons of acting force with dozens of kilograms of acting force, and even if the suspension ring is damaged, dangers cannot be caused. The time-saving and effort-saving testing device also has obvious positive significance on inevitably shortening the construction period and saving the testing cost economically.

Description

technical field [0001] The invention relates to the technical field of ship and marine engineering construction, in particular to a load test device for a ship's suspension ring. Background technique [0002] During the construction of ships and ocean engineering, a large number of marine lifting rings will be installed. In order to verify the safety and stability of the hoisting ring, after the hoisting ring is installed and welded, a corresponding safety load test must be carried out, and the hoisting ring can only be used for hoisting operations after it is confirmed to be qualified. The traditional test method of marine rings is to use the heavy object lifting method, that is, hang weights or weights of corresponding weight on the rings, and use similar methods for subsequent operations to carry out physical verification. The weight of marine lifting rings is often as high as several tons, sometimes even tens of tons. This traditional test method requires a lot of weigh...

AI Technical Summary

Problems solved by technology

The weight of marine lifting rings is often as high as several tons, sometimes even tens of tons. This traditional test method requires a lot of weights or heavy objects, which is not only inconvenient to transport, time-consuming and laborious, but also dangerous and easy to operate cause personal injury and large property damage

This traditional test method obviously cannot meet the needs of modern fine shipbuilding and scientific shipbuilding
