【摘要】：本文分析研究了液压单轨吊起重运输装置在矿井中实际应用时存在的问题：如起重装置中的制动器采用制动盘与液压马达组合的方式,体积、质量过大,一方面使物料、设备的提升空间变小了,另一方面增加了整机的重量,需要提供更大的驱动力,造成液压系统压力较大；驱动装置采用液压马达与摩擦轮组合的方式,摩擦轮会出现打滑和易磨损的缺陷,造成后期维护成本较高。针对以上问题提出改进设计方案。如起重装置采用盘式制动电机,能够有效的减轻重量、缩小体积,从而增大物料、设备的提升空间和降低液压系统的压力；驱动装置采用液压马达与齿轮齿条组合的方式,能有效地解决使用摩擦轮存在的打滑、易磨损等现象。对改进方案的结构设计。通过理论分析,利用SolidWorks软件对单轨吊起重运输装置的主要组成部件进行结构设计,包括起重装置、驱动装置和辅助装置。起重装置包括起重壳体、盘式制动电机和传动机构(链轮链条),驱动装置包括驱动壳体、液压马达和传动机构(齿轮齿条),辅助装置包括运行轨道、悬挂组件和调距液压缸。对起重装置和驱动装置中的重要零部件进行有限元分析。对起重壳体和驱动壳体进行静力学分析,对减速器和齿轮齿条进行动力学分析,最后对起重装置中的关键零部件起重壳体进行优化设计。通过以上内容的研究,本课题所改进设计的单轨吊起重运输装置能够改善液压单轨吊体积、重量较大和打滑、易磨损的问题,而且结构较为简单,能够方便灵活的运输材料和设备。
[Abstract]:In this paper, the problems existing in the practical application of hydraulic monorail crane crane in mine are analyzed and studied. For example, the brake in the hoist adopts the combination of brake disc and hydraulic motor, the volume and mass of which are too large, on the one hand, the material is made, The lifting space of the equipment becomes smaller, on the other hand, it increases the weight of the whole machine, and needs to provide more driving force, which causes the pressure of the hydraulic system to be high; the driving device adopts the combination of the hydraulic motor and the friction wheel. The friction wheel will appear the defects of skidding and easy wear, resulting in higher maintenance cost in the later stage. To solve the above problems, an improved design scheme is put forward. If the lifting gear adopts disc brake motor, it can effectively reduce the weight and reduce the volume. Thus increasing the lifting space of materials and equipment and reducing the pressure of hydraulic system, the driving device adopts the combination of hydraulic motor and gear rack, which can effectively solve the skidding existing in the use of friction wheels. Through theoretical analysis, using SolidWorks software to design the main components of monorail crane crane transportation device, including lifting device, Driving devices and auxiliary devices. Lifting appliances include lifting housing, disc brake motor and transmission mechanism (chain wheel chain, driving device including drive housing, hydraulic motor and transmission mechanism (gear-rack), auxiliary device including running track, Suspension assemblies and adjustable distance hydraulic cylinders. Finite element analysis of important parts in hoisting gear and drive device. Statics analysis of hoisting shell and driving shell, dynamic analysis of reducer and gear rack, Finally, the optimization design of the hoisting shell, the key part of the hoisting device, is carried out. Through the research above, the improved monorail crane can improve the volume, weight and slip of the hydraulic monorail crane. Easy to wear and easy to wear, and the structure is relatively simple, can be convenient and flexible transport materials and equipment.
