Description

Technical Field

[0001] The utility model relates to the technical field of buried scraper conveyors, in particular to a bent section structure of a buried scraper conveyor. Background Art

[0002] In the field of buried scraper conveyors, there is often an arrangement in which materials are conveyed horizontally and then inclined. The material is transferred from horizontal conveying to vertical lifting or inclined conveying by a curved section. The curved section is welded with steel plates and bolted into one body. It is an arc-shaped closed shell with a rectangular cross-section. The flanges at both ends are respectively connected to the horizontal section and the middle section of the inclined section. The angle α between the flanges at both ends is the arrangement angle of the curved section. The curved section plays a connecting role in the entire buried scraper conveyor. At the same time, it is also a component in the buried scraper conveyor that is subjected to increased force and more severe wear.

[0003] The existing bending section only has a rail pressing device for the load-bearing scraper chain, and generally no upper rail pressing device is set for the return scraper chain. When the scraper chain is tensioned, the unloaded scraper chain may also be lifted upward due to the tensioning force, resulting in interference such as jamming, scraping, and collision between the unloaded scraper chain and the upper cover of the bending section. Utility Model Content
