Description

Gantry crane wire rope detection device Technical Field The invention relates to the field of hoisting equipment, in particular to a gantry crane steel wire rope detection device. Background In the fields of industrial production and logistics transportation, the portal crane is widely applied to places such as ports, wharfs and railway goods yards as an important hoisting device and bears the key tasks of loading, unloading, carrying and the like of goods. The device is just like a key gear in a logistics hub which runs efficiently, ensures smooth circulation of goods among different transportation links by strong lifting capacity and flexible operation performance, and is an important support for guaranteeing stability of a logistics supply chain and continuity of industrial production. The steel wire rope is used as a key bearing component of the portal crane, and the performance state of the steel wire rope is directly related to the operation safety and reliability of the crane. Under the complex and changeable working condition of the portal crane, the steel wire rope not only bears huge axial tension, but also greatly fluctuates along with the weight change of the lifted goods, and extremely high requirements are provided for the strength and toughness of the steel wire rope. Meanwhile, the device can be acted by lateral force generated by factors such as lateral wind load, crane swing and the like. For example, in harbour operations, strong sea winds can generate continuous lateral thrust on the wire rope suspended in the air, and the wire rope can also be subjected to lateral pulling force due to inertia during starting, braking or moving of the crane. The lateral forces can lead the steel wire rope to generate deformation such as bending, twisting and the like, and the steel wire rope is in the complex stress environment for a long time, so that friction among steel wires in the steel wire rope is aggravated, and faults such as abrasion, fracture and the like are extremely easy to occur. The consequences are not envisaged once the wire rope fails. If the weight is light, the goods fall, equipment damage and goods loss are caused, and normal production operation progress is influenced, and if the weight is heavy, serious safety accidents such as crane overturning and the like can be caused, the life safety of on-site staff is threatened, and huge economic loss and bad social influence are brought to enterprises and society. In order to improve the service life and operation safety of the steel wire rope, the mechanical properties, surface abrasion conditions and the like of the steel wire rope need to be detected by using detection equipment.
