Belt breakage protection device for belt conveyer

Abstract

The invention discloses a belt breakage protection device for a belt conveyer. The belt breakage protection device comprises a rack, a capture mechanism and a trigger mechanism. The capture mechanism comprises an upper conveyer belt capture part and a lower conveyer belt capture part. Each of the upper conveyer belt capture part and the lower conveyer belt capture part comprises a moving capture part and a fixed capture part. The moving capture parts can swing towards and get close to the fixed capture parts and can be matched with the fixed capture parts to form clamping gaps capable of capturing a broken belt of the belt conveyer. The trigger mechanism comprises clamping parts which are used for locking the moving capture parts and connecting rod components which are used for driving the clamping parts to turn over. The clamping parts are arranged on the two sides of the bottom end of the upper conveyer belt capture part and on the left side and the right side of the lower conveyer belt capture part. The belt breakage protection device for the belt conveyer has the advantages that the structures of the capture mechanism and the trigger mechanism are simple, the moving parts are few, the hydraulic or electro-hydraulic parts are not needed, the reliability is high and the situation of capture failure due to clamping stagnation caused by dust and sundries is not apt to occur.

Description

Technical field [0001] The invention belongs to the technical field of belt conveyors, and in particular relates to a belt-breaking protection device for belt conveyors, which is suitable for the upper and lower layers of belt conveyors for material transportation in mining, metallurgy, chemical industry, light industry, coal, and ports Belt break protection of the conveyor belt. Background technique [0002] At present, as the main conveying equipment for bulk and bulk materials, belt conveyors are widely used in many fields such as mining, metallurgy, chemical industry, light industry, coal, and ports. However, during operation, once the conveyor belt occurs Falling down of the broken belt or a reversal accident caused by the failure of the backstop will destroy the conveyor frame, damage the equipment, block the transportation lane, cause long-term shutdown, heavy economic losses, and even casualties. In view of the conveyor belt fracture accident, the most important protecti...

AI Technical Summary

Problems solved by technology

[0003] 1. The capture device can only simply capture the upper conveyor belt, and there is no linkage mechanism between the upper conveyor belt and the lower conveyor belt, which easily causes secondary damage to the broken belt

[0004] 2. The capture device and the conveyor share a frame, and its strength is low, and the frame may be deformed during capture

[0005] 3. The arresting device relies on the movement caused by the reverse running caused by the broken belt to trigger the action. However, due to the complexity of the operating environment, the speed of the conveyor belt changes, the local tension disappears, and the drooping displacement increases, which is easy to cause arrest. The device malfunctioned and affected the production

[0006] 4. There are many transmission parts in the capture device, and dust and materials can easily block the movement of the moving parts. The transmission mechanism in some technical solutions is quite complicated, even including many electrical and hydraulic components, which virtually reduces the capture device. reliability

[0007] 5. There is a lack of necessary considerations in the design of the capture device, resulting in a large amount of work and difficulty in the installation, adjustment and maintenance of the capture device, making it difficult to ensure the good working condition of the capture device and the reliability of the capture action
