Monitoring system and method for dynamic operation track of lifting machine

Abstract

The invention discloses a monitoring system and method for a dynamic operation track of a lifting machine. According to the method, real-time dynamic collection of fixed-point sound track is carried out on friction sound between a wheel and a track through a fixed-point sound collecting cover, real-time positioning is carried out through a position indicator, and then the fixed-point sound track is compared with a set mother sound track through a CPU so as to detect abnormal conditions in real time and give an alarm. According to the system and the method, the travelling tracks of large lifting devices can be dynamically monitored under a less-people state and an unmanned state, the system is a whole set of system with integrity, in actual production, the problem that the lifting machine track is abnormal can be effectively solved, the lifting safety operation rate is improved, abnormal accidents are prevented, the safety of the production logistics is effectively controlled, so that the effect of solving the production safety problem is achieved.

Description

technical field [0001] The invention relates to a detection technology for abnormal deformation of a track, in particular to a track monitoring system and method for the dynamic operation of a hoisting machine. Background technique [0002] The crane track is a crane running route made of steel rails, which ensures that the crane runs along the specified route and transmits wheel pressure to the foundation. Because the track under high pressure and high load for a long time will appear cracking, loose deformation and other phenomena, resulting in unstable operation of the crane and abnormal vibration. [0003] The current safety inspection of the track includes: checking whether the track, bolts, and splints are cracked, loose and corroded. If cracks are found, they should be replaced in time, and if there are other defects, they should be repaired in time. The main inspection tool is a rail flaw detector. The flaw detector uses the ultrasonic method to detect rail damage....

AI Technical Summary

Problems solved by technology

However, it is difficult to accurately measure the condition of the entire track when measuring a super-long track, and the effect is not ideal

The other is to regularly (3-6 months) conduct regular flaw detection for the track arrangement. The disadvantage is that only 2 flaw detection inspections a year cannot ensure the safety of the track

However, in actual production, due to the frequent lifting and frequent stops, and the long-term dynamic operation under the state of high-intensity load, the damage to the track is very high, which brings a very large workload to the inspection personnel and cannot achieve real-time monitoring. In the safe state of the track, if the track cracks, there may be serious consequences of abnormal jumping of the crane when it is running, and what is more, it will cause an accident that the crane will splash molten iron
