Monitoring and Warning Method of Falling Arrestor's Braking State in Aerial Work
In order to improve the poor prediction of monitoring anti-fall braking status due to the post-accident recognition of the sensing signal and ignore of the pre-war impact mechanical characteristics of brake rope,a method of monitoring and warning the fall arrest braking status of the fall arrest device for aerial work is proposed by introducing the impact mechanical characteristics of the brake rope.The impact mechanics of the brake rope of the fall arrester is analyzed,and the mechanical characteristics are introduced into the relevant conditions of the fall arrest braking process.According to the braking deceleration,braking force and braking distance,the threshold range of the fall arrest braking status is established.Different sensors are used to collect the state data changes during the anti-falling braking process,and the actual anti-falling braking force is compared with the threshold interval to determine whether an early warning is needed.The experimental results show that the proposed method has high precision of condition monitoring and early warning.
