Problems solved by technology

The broken belt catcher is used as a supporting roller under normal conditions. When a broken belt occurs, the tension of the conveyor belt drops suddenly, and the upper and lower belt catchers are triggered by the gravity of the parts to catch the broken belt. Although the belt catcher can catch the upper and lower tapes at the same time after the broken belt, but because of the fast catch, it is easy to cause a great impact on the conveyor fuselage during the catch process, causing the fuselage damage to parts

Abstract

The invention discloses a belt-broken protective device with a deceleration function. The belt-broken protective device comprises a rack and a capturing mechanism. The capturing mechanism comprises an upper conveyor belt capturing part and a lower conveyor belt capturing part. The upper conveyor belt capturing part comprises a movable upper capturing branch part which can swing upwards under the action of the gravity and a static upper capturing branch part arranged on the upper portion of the rack. The movable upper capturing branch part swings towards and near the static upper capturing branch part which is located above the movable upper capturing branch part, and an upper portion clamping gap is formed by the match of the movable upper capturing branch part and the static upper capturing branch part and is capable of capturing an upper conveyor belt. The static upper capturing branch part is an upper portion capturing beam, and the upper portion capturing beam comprises a regulator for buffering and decelerating. The regulator comprises a static beam, a movable beam and a damping structure, wherein the movable beam locates below the static beam and is capable of moving upwards under the action of the upper capturing movable branch part, and the damping structure is used for supplying resistance for the upward movement of the movable beam. The regulator is arranged to supply a deceleration effect on capturing a conveyor belt, so that the impact and damage on the rack during a capturing process are reduced, and the service life of the rack is prolonged.

Description

technical field [0001] The invention relates to a broken belt protection device, in particular to a broken belt protection device with deceleration function. Background technique [0002] Belt conveyors are widely used in many fields such as mining, metallurgy, chemical industry, light industry, coal, ports, etc. With the increase of conveying distance, wear caused by conveyor belt transmission and maintenance errors, belt conveyors will be damaged during operation. In the event of a broken belt accident, in order to avoid huge losses caused by a broken belt accident, a broken belt arresting device is generally installed on the belt conveyor. [0003] Patent CN201713083U discloses a broken belt catcher for a belt conveyor, which includes an upper tape catcher and a lower tape catcher. The upper catch static part fixed on the upper part of the frame, the upper catch dynamic part swings to and approaches the upper catch static part above it, and cooperates with the upper catc...
