Marine engineering crane anti-fall device based on principle of centrifugal force

Abstract

The invention relates to the technical field of marine engineering, and discloses a marine engineering crane anti-fall device based on the principle of centrifugal force. The marine engineering craneanti-fall device based on the principle of the centrifugal force comprises a crane arm, a first fixing plate is fixedly connected into the crane arm, a steel cable is movably connected into the firstfixing plate, a limiting block is fixedly connected to the outside of the first fixing plate, a sliding block is slidably connected to the outside of the limiting block, a return spring is movably connected into the sliding block, a fixed block is fixedly connected to the outside of the sliding block, a convex block is movably connected to the outside of the sliding block, and a fixed disc is fixedly connected to the outside of the convex block. Through the cooperative use of a centrifugal disc, a pawl sliding bar and a positioning disc, the effect that when the object falls, the rotating speed of the centrifugal disc is improved, so that the pawl sliding bar automatically locks the positioning disc is achieved, the operation is simple, the locking is automatic, the control is accurate, the response is timely, the probability of accidents is effectively reduced, and the life safety of the staff is protected.

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....

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
