An anti-drop device for marine engineering cranes based on the principle of centrifugal force

Abstract

The present invention relates to the technical field of ocean engineering, and discloses an anti-falling device for an ocean engineering crane based on the principle of centrifugal force, comprising a crane arm, the inside of the crane arm is fixedly connected with a first fixing plate, and the inside of the first fixing plate has a A steel cable is movably connected, the outside of the first fixing plate is fixedly connected with a limit block, the outside of the limit block is slidably connected with a slider, and the inside of the slider is movably connected with a return spring, and the The outside is fixedly connected with a fixed block, and the outside of the slider is movably connected with a bump, and the outside of the bump is fixedly connected with a fixed plate, through the cooperation of the centrifugal plate, the pawl slide bar and the positioning plate, so as to achieve When falling, the rotational speed of the centrifugal disc increases, so that the pawl slide bar automatically locks the positioning disc. The operation is simple, automatic locking, accurate control, timely response, effectively reducing the probability of accidents and protecting the safety of workers.

Description

technical field [0001] The invention relates to the technical field of ocean engineering, in particular to an anti-drop device for an ocean engineering crane based on the principle of centrifugal force. Background technique [0002] Ocean engineering refers to new construction, reconstruction, and expansion projects for the purpose of developing, utilizing, protecting, and restoring marine resources, and the main body of the project is located on the seaward side of the coastline. It is generally believed that the main content of ocean engineering can be divided into resource development technology and equipment facilities There are two major parts of technology, and in offshore engineering construction, offshore cranes are an indispensable part. [0003] However, the existing offshore cranes are not perfect in terms of anti-falling and anti-cable breakage during operation, and there is a danger of falling. They do not have a self-locking function and are prone to accidents....

AI Technical Summary

Problems solved by technology

[0003] However, the existing offshore cranes are not perfect in terms of anti-falling and anti-cable breakage during operation, and there is a danger of falling. They do not have a self-locking function and are prone to accidents. Often, even if an anti-falling device is installed, Usually, the operation is complicated and cumbersome, or it is only located in the motor transmission area. There is no anti-drop self-locking device at the crane arm of the offshore engineering crane. If the steel cable breaks at the crane arm, it is very easy to Occurrence of operational hazards, leading to safety accidents
