锚杆机滑架磨损修复工艺研究

Study on the Repair Process for the Roof Bolter Carriage Wear

掘锚机组是煤矿井下短壁开采的主要设备,由其配备的锚杆机及时完成对顶板打锚杆支护,作为锚杆机主体和主要结构的滑架由于工作情况恶劣、作业负荷大,随着钻箱来回运动,以及设备超期、超负荷作业等,造成滑架过度磨损,不但影响井下正常生产作业、设备大修工期与质量,而且造成零件报废堆积、资产浪费。本文通过选用合理的修复材料和工艺,对磨损表面进行修复,经修复合格的滑架成功应用于设备大修,不仅节省了配件成本,而且为类似零件修复提供经验与借鉴。

Bolter-miner unit is the main equipment for short-wall mining in coal mine,and the roof bolter equipped provides the bolt support for the roof in time.As the main body and the main structure of the roof bolter,the carriage is excessively worn due to the bad working conditions,the heavy working load,the back-and-forth movement of the drill box,the overdue and overloaded operation of the equipment,etc.,which not only affects the normal production operation,overhaul period and quality of the equipment in the mine,but also causes scrap accumulation of parts and waste of assets.In this paper,the wear surface is repaired with proper repair materials and processes.The qualified carriage after repair is successfully applied to equipment overhaul,which not only saves accessory cost,but also provides experience and reference for the repair of similar parts.
