Claims

[Scope of utility model registration request]

A mechanism that is placed between the brake bands arranged on the outer peripheral surfaces of the two drums A and B arranged in parallel and the drums A and H, and that generates a pressing force on both brake bands against the drum outer peripheral surfaces. and a mechanism for arranging the brake band of drum A and the brake band of drum B such that their dead side ends and live side ends face each other,
A link support frame whose both ends are pin-connected to a fixed frame, and a first link whose one end is pin-connected to the dead side end of the brake band of drum A and the other end is pin-connected to one end of the link support frame. and a second link which is rotatably connected to the link support frame and which has one end connected to the live side end of the brake band of drum A and the other end pin connected to the brake operation system link, and one end. a third link which is connected by a pin to the put-side end of the brake band of drum B and the other end to the other end of the link support frame, and a third link which is rotatably connected to the link support frame and has one end A band-type brake device for parallel drums, characterized in that the fourth link is connected to the drive side end of the brake band of the drum B, and the other end is connected by a pin to the brake operation system link.
