带式输送机用弹性拉紧装置的设计研究

弹性拉紧装置是带式输送机固定拉紧装置的一种,采用弹簧套筒与绞车-滑轮的组合实现弹性拉紧的作用,提供了一种响应快速、结构简单、使用便捷的绞车拉紧装置。主要解决输送机在启动过程中因输送带弹塑性变形而引起的"打带"、打滑、冲击等问题。弹性拉紧装置在中、短型且拉紧行程不大的带式输送机中是理想的拉紧装置,它的应用可获得良好的技术和经济效益并具有一定推广价值。

The elastic tension device is a kind of fixed tension device of belt conveyor,and the combination of spring sleeve and winch pulley is used to realize the elastic tension.It provides a fast,simple,easy to use winch to tighten the device.The main solution is the"belt",skid and impact of conveyor belt elastic-plastic deformation during starting process.Elastic tension device in the medium,short and tighten the belt conveyor in the little trip is the ideal tension device,the application of he could get good technical and economic benefits and has certain popularization value.
