AI Technical Summary
Technical Problem
现有技术中，耐磨帽平均每工作48小时即发生脱落，耐磨帽脱落后，齿座直接暴露于磨蚀性介质中，磨损速率显著提升；频繁更换耐磨帽及修复齿座导致材料与人力成本上升；脱落部件可能飞溅伤人或损坏设备，且停机检修影响作业连续性
Benefits of technology
本申请实施例提供了一种露天煤矿电铲齿座耐磨帽的防脱落装置，通过设置防脱落装置与齿尖一体化成型，消除传统分体式结构的连接薄弱点，显著提升整体刚性和抗冲击性能；且防脱落装置采用楔形结构，降低作业阻力，楔形轮廓优化应力分布，减少与物料的接触摩擦；延长使用寿命，通过应力分散避免局部疲劳裂纹，延长部件服役周期。

Abstract
The application provides a falling prevention device for a wear cap of a tooth holder of an electric shovel in an open-pit coal mine, and belongs to the technical field of open-pit coal mining equipment. The falling prevention device comprises a tooth tip and a falling prevention device. The falling prevention device is a wedge-shaped structure, the falling prevention device is arranged on the tooth tip, and the falling prevention device is integrally formed with the tooth tip. The falling prevention device can reduce the falling rate of the wear cap by more than 80%, prolong the service life of the tooth holder by 2 times, and greatly reduce the annual maintenance cost. The falling prevention device can avoid the risk of component splashing and reduce the unplanned downtime of the equipment. The maintenance frequency is prolonged from every 48 hours to more than 200 hours, and the labor intensity of workers is greatly reduced.
