Belt breakage protection device with speed reducing function

Abstract

The invention discloses a belt breakage protection device with a speed reducing function. The belt breakage protection device comprises a machine frame and a capturing mechanism. The capturing mechanism comprises an upper conveying belt capturing portion and a lower conveying belt capturing portion. The upper conveying belt capturing portion comprises a movable upper capturing part which can swing upwards under the effect of gravity and a fixed upper capturing part installed on the upper portion of the machine frame, the movable upper capturing part swings towards and moves close to the fixed upper capturing part located above the movable upper capturing part and is matched with the fixed upper capturing part to form an upper clamping gap which can be used for capturing an upper conveying belt, the fixed upper capturing part serves as an upper capturing cross beam, the upper capturing cross beam comprises a regulator used for buffering and speed reducing, and the regulator comprises a static beam, a movable beam which is located below the static beam and can move upwards under the effect of the movable upper capturing part and a damping structure arranged between the static beam and the movable beam. Through the arrangement of the regulator, a speed reducing effect can be realized for capturing of the conveying belt, impact damage to the machine frame in the capturing process is reduced, and therefore the service life of the machine frame is prolonged.

Description

technical field [0001] The invention belongs to the technical field of belt conveyors, 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 protection 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 upp...

AI Technical Summary

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
