Description

Technical Field

[0001] The utility model belongs to the technical field of conveyor chains, and more specifically, particularly relates to a conveyor chain structure. Background Art

[0002] The conveying performance of the conveyor chains used in some conveying occasions in China is relatively low. When the conveyor chain is conveying heavy materials, a large-pitch chain is generally used. A conveyor attachment plate is set on the side of the outer chain plate of the large-pitch conveyor chain to convey large loads and improve the conveying performance.

[0003] Based on the above, most of the conveyor attachment plates on the existing conveyor chains are directly welded to the outer chain plates. Once the conveyor attachment plates are deformed during the conveying process, the corresponding outer chain plates need to be replaced. The outer chain plates and the inner chain plates are connected by chain shafts. Therefore, during the maintenance process, the outer chain plates and the inner chain plates on the corresponding conveyor chain nodes need to be disassembled and the corresponding outer chain plates need to be replaced. The maintenance process is relatively cumbersome, and causes waste of outer chain plates, increasing maintenance costs. Utility Model Content
