レーキ兼用手動巻上装置。[Claims for Utility Model Registration] Inside the casing 11 is a rotary plate 12 for braking the motor,
The chain wheel 13 and the brake plate 16 are arranged concentrically in series, and the rotary plate 12 is arranged with respect to the casing 11.
The brake plate 1
6 is slidably supported only in the axial direction, and the rotary plate 12 is configured to be brakeable by pressing the brake plate 16 against the rotary plate 12 through the chain foil 13 with a braking spring 18 to bring them into frictional contact.
The rotary plate 12 is configured to be able to release the brake by separating the chain wheel 13 from the rotary plate 12 with a brake release device 20, and a pair of chain guide holes 11b, 11b are formed in the bottom wall of the casing 11 below the chain wheel 13. , the hoisting operation chain 15 is passed through both chain guide holes 11b and wound around the chain wheel 13, a reverse rotation prevention device 25 is provided between the chain wheel 13 and the casing 11, and the reverse rotation prevention device 2 is provided.
5, the non-return pawl 26 is engaged with the engaging pawl 28 by the engaging biasing means 29.
In a manual hoisting device that also serves as a brake for an electric shutter hoist, the non-return pawl 26 is supported by the casing 11 and the engaging pawl 28 is fixed to the chain wheel 13. A check pawl installation hole 27 is opened in the bottom wall of the casing 11 at an intermediate position between the pair of chain guide holes 11b, and the check pawl 26 is inserted into the check pawl installation hole 27, and the bottom circumferential surface of the chain foil 13 is Casing 1
1, and the engaging claw 28 of the reverse rotation prevention device 25 is supported by the chain engaging groove 1 formed on the outer peripheral surface of the chain wheel 13.
The chain transmission abutment claws 14b located at multiple locations in the circumferential direction of the chain transmission abutment claws 14b are used for the same purpose, and the check claws 26 are engaged with the chain engagement groove 14 by the engagement biasing means 29, and the chain transmission abutment claws 14b are engaged with the chain transmission abutment claws 14b. A manual hoisting device that also serves as a brake for an electric shutter hoisting machine, characterized in that it is configured to be engaged.
