The invention relates to the technical field of crane walking devices, in particular to a crane cart walking device which comprises a mounting frame, a pneumatic assembly corresponding to a walking wheel body is arranged in the mounting frame, and the output end of the pneumatic assembly is provided with an oiling assembly, an air blowing assembly and a powder spraying assembly. The output end of the driving device is further provided with a speed reduction assembly which intermittently controls the oil adding assembly to communicate with the pneumatic assembly, the pneumatic assembly is matched with the powder spraying assembly and the oil adding assembly, the instant lubricating effect can be provided when the traveling wheel body is started and braked, abrasion to the surface of the traveling wheel body due to the slipping phenomenon is reduced, and the service life of the traveling wheel body is prolonged. The first control assembly in the oiling assembly controls injection of lubricating oil through rotation of the blocking disc, it is guaranteed that the walking wheel body has enough lubricating oil in the advancing process, abrasion is reduced, and meanwhile negative effects caused by excessive lubrication are avoided.
本发明涉及起重机行走装置技术领域,具体地说,涉及一种起重机大车行走装置,其包括安装架,安装架内设置有与走轮本体相对应的气动组件,所述气动组件的输出端分别设置有加油组件、吹气组件和喷粉组件,所述驱动装置的输出端上还设置有间歇控制加油组件与气动组件连通的减速组件,通过设置气动组件与喷粉组件、加油组件的配合,有利于在走轮本体启动和制动时提供即时的润滑效果,减少因打滑现象对走轮本体表面的磨损,加油组件中的第一控制组件通过阻挡盘的转动,控制润滑油的喷射,确保走轮本体在行进中有足够的润滑油降低磨损,同时避免了过量润滑导致的负面影响。
