Description

Bridge crane wire rope replacement device Technical Field The application relates to the technical field of bridge cranes, in particular to a bridge crane steel wire rope replacing device. Background Bridge crane is a core device for loading and unloading operations of container terminals of modern ports, and is used for efficiently and safely lifting containers between ships and terminals, and is used as a 'principal force army' of an automatic and intelligent port. In the bridge crane device, the steel wire rope is a core component of a bridge crane lifting mechanism, and the power of a motor is transmitted to a lifting appliance through a hoisting system, so that the vertical lifting of the container is realized. The wire rope needs to be replaced due to wear during use for a period of time. At present, the steel wire rope is replaced by lifting a winding drum wound with the steel wire rope through a travelling crane, one end of the steel wire rope is connected with a lifting mechanism, the lifting mechanism pulls the steel wire rope, the winding drum synchronously rotates, but the whole mass of the steel wire rope is large, the inertia is large, stall easily occurs in the rotation process of the winding drum, and the potential safety hazard is high. Disclosure of utility model In order to reduce the condition that a winding drum stalls during the replacement of a steel wire rope, the application provides a bridge crane steel wire rope replacement device. The application provides a bridge crane steel wire rope replacing device which adopts the following technical scheme: The utility model provides a bridge crane wire rope changing device, includes the support base and sets up in the rotary mechanism who supports the base, rotary mechanism including rotatory install in the rotary disk at support base top, set up in thrust bearing of rotary disk bottom and be used for restricting rotary disk pivoted brake assembly.
