The brake device is mounted on a rear end cover at the tail of a driving motor, a mounting disc, a brake disc and a spring chassis are sequentially arranged on the rear end cover, a handle is arranged on the outer side of the spring chassis, and a one-way clutch rotating mechanism, a friction disc and a lifting disc are sequentially arranged between the mounting disc and the brake disc. A motor transmission shaft penetrates through the installation disc to be connected with the clutch rotating mechanism. The one-way clutch rotating mechanism for limiting one-way rotation of the motor transmission shaft is arranged inside, rotation of the motor transmission shaft is stopped when the motor transmission shaft rotates reversely, electric driving is not needed, and braking can be completed by means of the gravity of equipment and loads. The brake device is further provided with a handle, when the motor transmission shaft needs to rotate reversely, only the handle needs to be pulled to rotate in the radial direction, so that the friction disc and the one-way clutch rotating mechanism are longitudinally separated, the limiting disc is gradually released, the friction disc and the rotating disc can rotate reversely together under driving of the motor transmission shaft, and the brake device has the advantages of being convenient to operate and safe to operate.
本发明公开了一种适用于便携式升降器的制动装置,安装于驱动电机尾部后端盖上,后端盖上依次设置有安装盘、制动盘和弹簧底盘,弹簧底盘的外侧设置手柄,安装盘和制动盘之间依次设置有单向离合旋转机构、摩擦盘和提拉盘,电机传动轴穿过安装盘与离合旋转机构连接。本发明通过在内部设置限制电机传动轴单向旋转的单向离合旋转机构,在电机传动轴反转时阻止其转动,无需电力驱动,依靠设备及负载自身重力即可完成制动。该制动装置还配备有手柄,当电机传动轴需要进行反转时,只需将手柄沿径向拉动旋转,使得摩擦盘与单向离合旋转机构纵向分离,限位盘逐渐被释放,在电机传动轴的驱动下即可与旋转盘共同反转,具有操作方便且操作安全的优点。
