摘要矿用提升设备是连通井上和井下工作的重要枢纽，是矿井的咽喉部位。一旦矿井提升机发生事故，势必会影响到煤矿的正常运转，充分体现了矿用提升系统对煤矿生产的重要性。矿用提升机主要工作就是为地下开采工作运送物料和人员，并将开采好的煤矿运到地面。随着煤矿技术的发展，矿用提升机的运行速度越来越高，提升量也越来越大，整体向着集中化和大型化发展，因此矿用提升机能否实现安全可靠的运行越来越重要。目前矿用提升机采用的保护措施主要有电气保护和后备保护两种，但提升机过卷过放事故依然存在，轻则造成设备损坏，重则会有人员伤亡。目前，我国不管是摩擦式提升还是缠绕式提升矿井没有装设缓冲托罐装置的占到80%以上，这严重威胁到了煤矿的安全生产，如果发生安全事故，设备将会受到严重损坏，给矿场生产带来巨大的经济损失。
缓冲托罐装置由井上防过卷和井下防过放两部分组成。井上缓冲系统包括：上缓冲平台、缓冲钢丝绳、制动钢丝绳、上生根夹具、下生根夹具、变力吸能器、缓冲器、托爪等；井下缓冲系统包括：下缓冲平台、制动钢丝绳、上生根夹具、变力吸能器等。结构简单，安装方便，性能可靠，而且可以根据不同的井深、井宽、提升速度、提升重量以及井架结构来改变防过卷过放缓冲托罐装置的各项参数。总的来说，就是该缓冲系统可以随着立井提升系统的改变而改变，任何一种立井提升都可以设计出一套相应的防过卷过放缓冲托罐装置。85043

Abstract Mine hoisting equipment is an important hub of communicating well and well working, and it is the throat area of mine。 Once the mine hoist accident, it is bound to affect the normal operation of the coal mine, fully reflects the importance of mine hoist system for coal mine production。 The main work of the mine hoist is to transport the material and personnel for the underground mining work, and will be transported to the ground。 With the development of the technology of coal mine, mine hoist machine run faster and higher, lifting capacity is more and more big, the overall toward centralization and large-scale development。 Therefore, mine hoist can realize the safe and reliable operation is getting more and more important。 The mine elevator adopt protection measures are mainly two kinds of electrical protection and backup protection, but hoist overwinding and overfalling accident still exist, ranging from damage to equipment, while there will be casualties。 At present, our country regardless of the friction hoist or winding mine hoist with no buffer and supporting cage device accounted for more than 80%, this is a serious threat to the safety in production of coal mine, if the occurrence of safety accidents and equipment will have serious damage and bring huge economic losses to the mine production。
The buffer supporting device is composed of two parts, which is inoue had anti-roll and underground anti-over-discharge。 Inoue had anti-roll buffer system include: on the platform of the buffer, buffer rope, brake steel wire rope, rooting fixture, rooting fixture, variable force energy absorbing apparatus, a buffer, a supporting claw; underground anti-over-discharge buffer system including: buffer platform, brake steel wire rope, rooting fixture, variable force energy absorbing device。 Simple structure, convenient installation, reliable performance and according to different well depth, well width, increase speed, to change the anti overwinding and overfalling buffers supporting cage device parameters to the ascent of the weight and structure of the derrick。 In general, that is, the buffer system can change with the shaft hoist system change, any kind of shaft hoist can design a set of corresponding anti had put buffer and supporting cage device。 矿用提升机缓冲系统设计及关键件有限元分析+CAD图纸:http://www.youerw.com/jixie/lunwen_101457.html
