设计简介
摘要
矿山提升设备是矿山运输中的咽喉设备,占有特殊地位,是井下与地面联系的主要工具。
矿山提升设备的用途是沿井筒提运矿石和废石,升降人员,下放材料、工具和设备。矿山提升设备在工作中如果一旦发生机械和电气故障就会造成停产,甚至人身伤亡。为了保证生产和人员的安全要求矿山提升设备运行准确,安全可靠,井必须配有性能良好的控制设备和保护装置。
矿山提升设备的耗电量一般占矿井总耗电量的30%一40%,所以为了降低矿石的成本,必须经济合理地选择和使用矿山提升设备。矿山提升设备又是矿井最大固定设备之一,是—套较复杂的机械-电气机组。
本文针对矿山机械的特殊要求,重点设计卷筒部件和主轴部件,两个部件是提升机的关键部分,卷筒强度不够导致的直接后果就是筒壳被压溃、焊缝开裂等;主轴是传递动力装置,在设计时需要考虑其承受的弯扭力矩,键对主轴强度的削弱及其装配问题,轴的工艺要求等。
通过本次的设计,可以缩短提升机设计周期,提高产品的设计质量,提高企业的技术创新能力和市场竞争能力。

Abstract
The mine lift technique is in the mine haulage pharynx and larynx equipment, holds the special status, and is the mine shaft and the ground relation main tool.
The mine lift technique use is picks up and ships the ore and the scrap rock along the well chamber, the fluctuation personnel, the release material, the tool and the equipment. Mine lift technique in work once if has the machinery and the electrical failure can create the production suspension, even person casualties. In order to guarantee the production and personnel's safety requirements mine lift technique movement is accurate, safe reliable, the well must have the performance good control device and the protective device.
The mine lift technique power consumption occupies the mine pit total power consumption generally 170%, therefore in order to reduce the ore the cost, must the economical reasonably choice and the use mine lift technique. The mine lift technique also is one of mine pit most greatly fixed equipments, is - the complex machinery - electricity unit.
This article in view of the mining machinery special request, the key design reel part and the main axle part, two parts is the elevator essential part, the direct consequence which reel under capacity causes is the tube shell is bruised, the welded joint dehiscence and so on; The main axle transmits the power unit, when design needs to consider its withstanding the crooked moment of force, the key to the main axle intensity weakening and the assembly question, the axis technological requirement and so on.
Through this time design, may reduce the lifting hoist design cycle, enhances the product the design quality, and enhances the enterprise technological innovation ability and market competition ability.
