合闸时间可以调节的液力推杆制动器,在日本引进的胶带输送机中普遍采用。笔者利用解体机会,绘制出内部结构图和工作原理图,并且对其工作原理作了较为详尽的叙述。按照以往概念,只是在有逆转可能时,才需设置逆止器、制动器。但在引进的胶带输送机系统中,即使是水平或稍微倾斜的输送机中都大量设置制动器。笔者根据统计材料、归纳得出的计算公式,可供选择时参考。
Closing time can be adjusted hydraulic push rod brakes, belt conveyors introduced in Japan are commonly used. I use the opportunity to disintegrate, draw the internal structure diagram and working principle diagram, and its working principle made a more detailed description. According to the previous concept, it is only necessary to set a backstop and a brake when reversing is possible. However, in the introduction of the belt conveyor system, even a horizontal or slightly inclined conveyor is provided with a large number of brakes. According to the author of the statistical material, summarized the calculation formula, available for reference.
