移动伸缩带式输送机设计.rar

摘 要:传统的带式输送机给汽车、火车、轮船装粮食及其它物料时，皮带机大多不能在原处一次性就装满货物，并且托辊夹角太小使皮带机倾角只能为17度，会给一些高大容器装载带来很多的困难。

　　　本论文设计内容是可伸缩带式输送机，通过传动滚筒与胶带之间的摩擦来传递牵引力，以胶带兼作牵引机构和承载机构的一种给料设备，托辊之间夹角增大可使皮带机倾角可达到25度，具有给料量大，运输平稳，维修方便，可多点卸料，占地面积小等特点，给装车带来方便，能广泛的应用于各种散料集散地的生产现场。

　　　本文论述了可伸缩带式给料运输机的总体设计方案，采用逐点张力计算以及功率计算相结合的方法选择给料机合理的参数，对该给料机的部件进行选型、设计和校核，其中，对驱动装置和伸缩装置进行了较为详尽的设计计算和校核。

ABSTRACT:With the traditional belt feeding engine when for the automobile, the train, the steamboat installs the coal and other materials, the belt fastener cannot in the original position disposable pack the cargo, because the supporting roller included angle slightly enables the belt fastener inclination angle only to be 17 degrees, brings many difficulties for some big vessel loading.

　　　The present paper design content is the expandable belt feeding engine, is transmits the force of traction through between the transmission drum and adhesive tape's friction force, concurrently makes the hauling organization and the load bearing organization one kind by the adhesive tape for the material equipment, expands and contracts the arm rear part establishment to have the expandable hydraulic prop, causes the complete machine length nimble elongation or the reduction, between the supporting roller the included angle increases to causes the belt fastener inclination angle to be possible to amount to 25 degrees, has for estimates in a big way, the transportation is steady, the service is convenient, the area slightly and so on characteristics, brings conveniently to the load, can the widespread application in each kind of bulk collection and distribution center production scene.

　　　This article elaborated the expandable belt feeding engine's overall project design, uses method choice feeding engine reasonable parameter which point by point the computation as well as the power calculation unify, carries on the shaping, the design and the examination to this feeding engine's part, and expanded and contracted the installment to the drive to carry on the more exhaustive design calculation and the examination.
