Structural Design and Analysis of Automatic Capture Device for the Belt Conveyor

In order to solve the problems of belt conveyor such as sudden rupture of belt, easy to cause equipment shutdown, lower benefit and even causing personal injury accidents, the fracture belt model of belt conveyor is established after analyzing the location and causes of the belt fracture in this paper, and a kind of mechanical fluid control type break capture device is put forward. The structure of break capture device is designed, and the supporting hydraulic control system is studied. The simulation loop model of hydraulic system is built by using the AMESim, and the sampling period is set at 0.01s for numerical simulation. The results show that in the parallel mode of dual accumulator, the pressure fluctuation of rod cavity and no rod cavity is small, and the capture time of the system when the pressure is 10MPa is 0.8s. The larger the pressure value of the system, the faster the oil release speed of the accumulator; it can realize rapid capture and braking, and effectively avoid personal injury caused by sudden belt break of the belt conveyor, which is of great promotion value and market prospect.
