一种5 t乳化液葫芦关键机械零部件要点分析

Analysis of Key Mechanical Parts of a 5 t Emulsion Hoist

摘要: 本文介绍了影响乳化液葫芦正常工作的主要机械结构件，并针对各主要零部件如下吊钩的铸钢盖板重载下的塑性变形、下吊钩链轮材质对承载能力的影响、链条材质对链条耐用性的影响、摩擦片材质不同对额定载荷条件下持续升降的影响、多头螺纹传动配合间隙和热处理等对乳化液葫芦性能的影响等，针对这些因素从实际工程应用角度提出了合理化的设计和改进思路，确保煤矿井下用乳化液葫芦长期良性工作。

Abstract: This paper introduces the main mechanical structure parts that affect the normal operation of the emulsion hoist. Considering the plastic deformation of the cast steel cover plate of the main parts, such as the hook under heavy load, the influence of the sprocket material of the lower hook on the bearing capacity, the influence of the chain material on the durability of the chain, the influence of different friction plate materials on the continuous lifting under rated load, the influence of multi-thread transmission clearance and heat treatment on the performance of the emulsion hoist, etc., In view of these factors, reasonable design and improvement ideas are put forward from the perspective of practical engineering application to ensure the long-term good work of the emulsion hoist used in coal mines.
