Description

Same-span crane overhauling safety laser limiting device and using method Technical Field The invention relates to the technical field of crane overhaul safety protection equipment, in particular to a same-span crane overhaul safety laser limiting device and a use method thereof. Background In the same-span multi-crane operation scene, when one crane is in a maintenance parking state, the existing safety protection mainly depends on the traditional mode of 'road clamp (material protection) +red flag (personal protection'). However, there are a number of significant limitations to this mode. On the one hand, due to the limitation of the site station layout, a crane driver needs to judge the speed-reducing and parking time by visual red flags. However, when the distance between the two stations is too short, or the distance between the crane and the red flag is too short, visual blind areas are very easy to generate, so that a driver can not find an overhaul area in time. On the other hand, even if a driver finds a red flag sign, the red flag and a road clip are collided due to the fact that the speed reduction operation is too late and the inertia effect of a cart, so that serious potential safety hazards such as equipment damage and even casualties are caused. It is counted that only half the year over 2025, the light collision event in the relevant scenario is as much as 3. In addition, the traditional protection mode needs to manually stare at the red flag, and the time for deploying the device is long before overhauling. Meanwhile, in order to pre-judge the distance in advance, the movable crane often needs to be decelerated in advance, which seriously affects the overall operation efficiency. In summary, the prior art lacks a common-span crane overhaul safety protection scheme capable of considering protection reliability, operation convenience and operation efficiency.
