Description

停电时能手动起落闸杆的道闸 技术领域
本发明涉及道闸，尤其是涉及一种在停电时能人力抬杆的停电时能手动起落闸杆的道闸。
背景技术
道闸又称挡车器，是专门用于道路上限制机动车行驶的通道出入口管理设备，现广泛应用于公路收费站、停车场系统管理车辆通道，用于管理车辆的出入。如停电时，道闸就不能正常工作，如果用人力进行开关时，现有的闸杆1a由于在水平位置时，参考图1，连杆4a与主动曲臂6a在同一条直线上；在闸杆1a竖直位置时，参考图2，连杆4a与主动曲臂6a重叠，形成传动结构的自锁状态，在此状态下，停电时，无法实现手动抬闸杆(人力的力矩传导到主动曲臂6a上不能形成偏移的效果，从而抬不动闸杆)，需要通过在电机轴端部安装摇把或手轮转动电机带动蜗轮蜗杆旋转从而实现闸杆起落，此方法费时费力，不利于现场操作；或通过在传动结构上安装离合器，通过分离离合器，实现手动抬闸杆，但此方法容易受闸杆的杠杆重力影响，不容易打开同时在外力的杠杆作用下大大增加了离合器的外力，使用过程中极容易损坏、故障率高，大大降低了离合器的使用寿命，此方法制造难度大，材料强度及精度要求高，增加了制造成本，不利于批量生产及现场操作。
发明内容

作为一种优选方式，所述减速箱为蜗轮蜗杆减速箱，其中的蜗杆为多头蜗杆。
作为一种优选方式，所述电机和减速箱为带有定位作用的智能电机。
