摘    要
关键词：1、TDTG50/24斗提机由机头、机座、机筒、观验机筒、减压机筒、畚斗、畚斗胶带、传动装置等部分组成。
        2、机头部件由机头座、机头盖、头轮、头轮轴、轴承座、密封盖等部分组成，机头座上设有检修窗及调整挡板。
        3、 中间节有三部分组成（1）观验检修机筒（2）普通机筒（3）减压机筒
（1）观验检修机筒
观验检修机筒设有检修门，可以供观验和检修之用，机筒由优质钢板折弯咬边联结，美观，强度好，密封性能佳，上下端焊接法兰，用于连接其他部件
（2）普通机筒   普通机筒没有检修门，其结构和观验机筒一样
（3）减压机筒    减压机筒可以使物料空气循环，机筒内压力平衡，空气流通更顺畅。
       4、传动装置一般采用摆线针轮减速电动机通过皮带传动（或者联轴器、及链轮传动）带动头轮轴传动，也可采用普通电动机通过皮带传动带动悬挂式轴装减速器，其减速器是套装在头轮轴的伸出端上。以上两种传动方式其电机（或减速电机）均应安装在电机架上，当斗提机设计高度小于10米时也可以安装在机座上。 

                               Abstract
   The lifting machine is one of the large-scale regular machine,used in the rise or fall and transport of various kinds of heavy objects. The small-scale lifting machine plays an important role too in daily life. TDTG50/24 lifting machine is made up of the head ,the middle one and motor,decelerator.It links by the shafts.The motor is the power source,the decelerator is a transmission,the cylinder,in order to carry out and control some,among then,the design of each part
   The head one is made up by  the basic segment , the hat ,the pulley ,the head shaft,and the bearing .There are some parts in order to check  the lifting machine .
   The middle parts are used to check the machine.There are three segments,including the cylinder.one,the checking one,and  the common one .
   The  cylinder one is made up by the window,which is used to watch and check the lifting machine.It looks very nice,and the force is enough.
  The common  one  dose not have the check one,and it looks like the above one .The part which lets down the press.It can make the air as a cycle .
The motor usually takes a decelerator..(the flexible coupling and the transport).It works by the shaft or by the common motor and decelerator .Both of  the two motors(or  decelerator)should put at the fixture,if the height is less 10 m  it also could put at the basic floor part of  the lifting machine .
  Key words:the lift machine, the decelerator ,TDTG50/24.
