多绳摩擦式提升机设计.docVIP

摘 要 矿井提升机是矿山井下生产系统和地面工业广场相联接的枢纽，是矿山运输的咽喉。因此，矿井提升机在煤炭运输行业占有极其重要的地位。其中多绳摩擦式提升机式现在使用最多的提升设备。 多绳摩擦式提升机是由安装于提升机摩擦轮(主导轮)筒壳上的摩擦衬垫来驱动钢丝绳，它是提升载荷的一个非常重要的零件，其摩擦性能的好坏，直接影响着提升机的工作能力、工作效率和安全性等。因此摩擦衬垫的选择主要应该有以下特点：一是摩擦性能要好，即与钢丝绳对偶的摩擦系数要高而稳定；二是不能损伤钢丝绳，即衬垫的硬度应低于钢丝绳。围绕这两个特点，选用聚氯乙烯为摩擦衬垫。摩擦提升机是靠摩擦衬垫与钢丝绳之间的摩擦力来传递动力, 由此可能出现滑动事故。因此必须进行防滑验算。制动系统是提升机不可缺少的重要组成部分, 是提升机最后一道也是最关键的安全保障装置, 制动装置的可靠性直接关系到提升机的安全运行。本文对制动器进行设计。摩擦轮是多绳摩擦式提升机的主要承载部件，在这次设计中采用经验公式对摩擦轮壳进行验算与校核。制动器是这次设计中的一个重要工作。 关键词：摩擦轮 ；制动器 ；防滑 ；摩擦衬 ABSTRACT Mine hoist is mine production system and the ground industrial square connected hub, is the throat of the mining transport. Therefore, mine hoist in coal transportation industry occupies an extremely important role. The rope friction type hoist type now use most lifting devices. More rope friction type hoist is installed in the ascension machine by friction wheel (leading wheel) and friction cylinder liner to drive the wire rope, it is to promote the load of a very important parts, the friction the performance, the direct impact on the machine work ability, improve work efficiency and safety, etc. So the choice of friction pad main should have the following characteristics: a friction performance is better, that is, the friction coefficient and wire rope dual to high and stable; 2 it is not damage wire rope, namely the pad should be below the hardness steel rope. Around the two characteristics, use of polyvinyl chloride for friction liner. Friction hoist is by friction friction between the pad and wire rope to deliver the power, may appear sliding accident. So to prevent slippery checked. Hoist brake system is an important and indispensable part, is to promote the machine a final also the most essential security device, braking equipment reliability directly related to improve the safety operation of the machine. In this paper, the design of the brakes. Friction wheel is more friction type hoist rope of the main bearing parts, in the design with experience formula in the friction wh
