Abstract
The utility model discloses a belt breakage protection device with the deceleration function. The belt breakage protection device comprises a machine frame and a capturing mechanism. The capturing mechanism comprises an upper conveyer belt capturing portion and a lower conveyer belt capturing portion. The upper conveyer belt capturing portion comprises an upper capturing movable branch portion capable of swinging upwards under the gravity effect and an upper capturing static branch portion installed at the upper portion of the machine frame. The upper capturing movable branch portion swings to the upper capturing static branch portion, is close to the upper capturing static branch portion above the upper capturing movable branch portion and is matched with the upper capturing static branch portion to form an upper-portion clamping gap capable of capturing an upper conveyer belt. The upper capturing static branch portion is an upper-portion capturing beam. The upper-portion capturing beam comprises a regulator used for buffering and decelerating. The regulator comprises a static beam, a movable beam which is arranged below the static beam and is capable of moving upwards under the effect of the upper capturing movable branch portion, and a damping structure generating resistance for the lifting motion of the movable beam. Due to the regulator, capturing of the conveyer belt can be decelerated, impact damage to the machine frame in the capturing process is reduced, and the service life of the machine frame is prolonged.
