破損防止用ブレーキ装置。 The main body of a main brake device that brakes a drive shaft driven by a main motor is integrated with an inching worm wheel, and a worm attached to an inching shaft driven by an inching motor meshes with the worm wheel. A brake device that is installed in an inching mechanism and brakes the inching shaft includes two arms that are rotatably provided at one end as a fulcrum, and each arm is provided with a friction pad and is attached to both arms and arranged to face each other. The inching shaft is disposed between a pair of brake shoes and the other ends of the two arms, and the two arms are biased toward each other by the elastic force of an internal return spring, and the inching shaft is moved between the two friction pads. an air cylinder that applies pressure to brake the air and releases the brake by expanding both arms when air is supplied; and a first air circuit that supplies relatively low-pressure air to the air cylinder when the main brake device is braking. and a second air circuit that supplies high-pressure air to the air cylinder at the same time as the start of the inching operation. A brake device for preventing damage to an inching gear.
