Belt break protection device with deceleration function

Abstract

The invention discloses a belt breakage protecting device with a deceleration function. The belt breakage protecting device comprises a frame and a capturing mechanism. The capturing mechanism comprises an upper conveyor belt capturing unit and a lower conveyor belt capturing unit. The upper conveyor belt capturing unit comprises an upper movable capturing sub unit and an upper fixed capturing sub unit, the upper movable capturing sub unit can swing upwards under the action of gravity, and the upper fixed capturing sub unit is mounted on the upper portion of the frame. The upper movable capturing sub unit swings to be close to the upper fixed capturing sub unit above, and an upper clamping gap for capturing an upper conveyor belt is formed by the upper movable capturing sub unit and the upper fixed capturing sub unit. The upper fixed capturing sub unit is an upper capturing cross beam which comprises an adjuster used for buffering and decelerating. The adjuster comprises a fixed beam, a moving beam and a damping structure. The moving beam positioned below the fixed beam can move upwards under the action of the upper movable capturing sub unit. The damping structure is used for generating resistance for upward movement of the moving beam. Through the adjuster, capturing of a conveyor belt can be decelerated, impact damage to the frame during capturing is reduced, and service life of the frame 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 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 upper cat...

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
