滚柱逆止器也用于向上运输的带式输送机上，在输送机正常工作时，滚柱在切口的较宽处，不会妨碍星轮的运转;当办平达 机停车时，在负载重力的作用下，输送带带动星轮反转，滚柱处在固定圈与星轮切口的狭窄处，滚柱被楔住，输送带被制动。
Roller backstop is also used in belt conveyor for upward transportation. When the conveyor is in normal operation, the roller in the wider incision will not hinder the operation of the star wheel; when the level machine stops, under the action of load gravity, the conveyor belt drives the star wheel to reverse, the roller is located in the narrow part of the fixed ring and the star wheel incision, and the roller is wedged. Stop. The conveyor belt is braked.
这种制动器制动迅速，平稳可靠，并且已经系列化生产，可参考DTII型系列标准，按减速器选配。所允许扭矩一般不超过20KN，但因其是安装在减速器的输出轴上，故适用于输送机的驱动电机容量较小的场合，功率范围为10kw-55KW。
This kind of brake is fast, stable and reliable, and has been serialized. It can be selected according to DTII series standard. The allowable torque generally does not exceed 20KN, but because it is mounted on the output shaft of the reducer, it is suitable for the occasion where the driving motor capacity of the conveyor is small, and the power range is 10kw-55KW.
