随着大倾角带式输送机向大角度、长距离、高速度、大功率方向发展，除驱动装置外，张紧装置是保证输送机正常启动、运行、制动、和停车的不可缺少的重要部件之一，直接影响带式输送机的安全可靠性和稳定性。大倾角皮带输送机可沿水平或倾斜线路运行，一般使用光面输送带，靠所运物料与输送带之间的摩擦力，带动物料一起运行，因而工作倾角受限制。向上一般不超20°，向下的倾角还要小些。为了能在更大的倾角上使用，节省材料及节省占地面积，增大皮带输送机倾角有着重要的意义。
本设计从大倾角皮带输送机的整体结构出发，对大倾角皮带机结构作了详细的论述。在皮带机起动阶段，能够在准确的时间开启皮带机；启动完毕后正常运行。此设计的特点是：可靠性高、倾角大、输送能力强等。

Abstract
With the big angle belt conveyor to the wide-angle, long distance, high speed, high-power direction, in addition to driving device, the tensioning device is normally the conveyor start, run, brake, and stopping an important and indispensablePart one of a direct impact on the safety belt conveyor reliability and stability.Inclined belt conveyor can be run along the horizontal or inclined lines, the general use of smooth conveyor belt, transported by the friction between the material and the conveyor belt to bring together materials to run, and therefore restricted the work of inclination.Up generally does not exceed 20 °, dip down even smaller.In order to use a greater inclination to save materials and to save area and increase the angle conveyor belt of great significance.
The design of inclined belt conveyor from the overall structure to the structure of large angle belt were discussed in detail.In the belt machine start-up phase, to open at the exact time of belt conveyor; start after running.This design features are: high reliability, dip angle, transmission capacity and strong.
Key words: high angle belt conyeyer；hydraulic robot stretcher； transmission system；
