Abstract:

PURPOSE: To prevent any rotational overspeed by the simple adjustment and also to enable a rotational overspeed preventing brake device to be used with maintenance free by providing a ratchet claw to be operated by a brake arm, while by providing a ratchet wheel capable of being engaged with the ratchet claw and stopped on a rotary shaft.

CONSTITUTION: In a rotational overspeed preventing brake device 30 for preventing the rotational overspeed of a takeup drum 22, a ratchet wheel 31 is attached by being integrated with the takeup drum 22, and ratchet claws 32 to be engaged with this ratchet wheel 31 are arranged on two parts on a diagonal line and rotatably attached to a frame 33, and connected to each other by connecting rods 35 through a rotational arm 34 attached coaxial with the rotational center of the ratchet wheel 31, thereby two ratchet claws 32 are interlocked. Accordingly, when the takeup drum 22 is placed in its rotatonal overspeed, two ratchet claws 32 are engaged with the ratchet wheel 31, thereby the takeup drum 22 can be stopped.
