Description

Technical Field

[0001] This utility model belongs to the technical field of bridge cranes, specifically relating to a detection device. Background Technology

[0002] Cold rolling mill bridge cranes operate continuously for long periods, with frequent daily tasks and extensive involvement in production activities. Due to factors such as the long construction time of some factory buildings, partial foundation settlement, substandard installation accuracy of the crane rails, and large diagonal deviations of the bridge cranes, the crane wheels experience wheel flange wear during rotation, leading to rapid wheel wear and frequent bearing failure. The main consequences are as follows: (1) Increased wear on wheels and rails Wheel misalignment causes uneven distribution of contact force between the wheel and the rail, with one side of the wheel bearing greater pressure and friction, leading to accelerated wear on that side. Simultaneously, the rail also experiences localized wear due to uneven stress, shortening the lifespan of both the wheel and rail, and increasing maintenance and replacement costs.

[0003] (2) Affects the stability of crane operation When a crane experiences wheel misalignment, its running trajectory will deviate, no longer running smoothly along a straight line. This will cause the crane to sway and vibrate during operation, severely affecting its stability. In severe cases of wheel misalignment, it may lead to crane derailment and cause a major safety accident.

[0004] (3) Increase running resistance Misalignment between the wheels and the rails causes wheel misalignment, which transforms the rolling friction of the wheels on the rails into partial sliding friction, thus increasing running resistance. This not only increases the crane's power consumption but can also lead to motor overload, overheating, and even damage to the motor and other transmission components.

[0005] (4) Damage to the crane structure The additional lateral force generated by wheel misalignment is transmitted to the crane's bridge structure through the wheels, causing the bridge to bear uneven loads. Over time, this can lead to deformation and twisting of the bridge, affecting the overall structural strength and stability of the crane. Furthermore, this uneven load can also damage the crane's outriggers, connecting components, and other parts, posing structural safety hazards.

[0006] The above-mentioned situations could lead to serious accidents and severely threaten the safe and stable operation of production tasks. Therefore, it is imperative to urgently develop a detection device to monitor the movement and posture of bridge cranes. Utility Model Content
