地下铲运机最大铲取力试验装置的设计

Design on jig and fixture of testing for maximum breakout force of underground load-haul-dump

铲运机最大铲取力的大小是衡量地下铲运机综合性能的一项重要参数。根据地下铲运机设计的技术要求,铲运机出厂前必须对最大铲取力进行测试。通过对铲运机的设计要求、技术参数及工作原理进行分析,并查阅了国内外各种相关资料,最终设计出了地下铲运机最大铲取力试验装置。这套装置具有其独创性,得到了国家质量检测中心的认可。实践证明,这套装置安全、可靠。文中主要介绍了该装置的设计依据、结构设计、强度校核、应用实例及实际使用效果。

The maximum breakout force is an important factor for appraising the comprehensive performance of the underground load-haul-dump. According to technical requirements, the maximum breakout force of the load-haul-dump must be tested before factory delivery. After analysis on the design requirements, technical parameters and working principle of the load-haul-dump, as well as reference of relevant data at home and abroad, the jig and fixture of testing for the maximum breakout force of the underground load-haul-dump was designed finally. The unique jig and fixture had been approved by National Quality Inspection Center. Practice showed that the jig and fixture was safe and reliable. In the paper, the jig and fixture was introduced about its design reference, structural design, strength verification, and application example and effects.
