Description

Technical Field

[0001] This utility model relates to the field of scraper conveyor technology, and in particular to an assembly and positioning fixture for a central trough. Background Technology

[0002] A scraper conveyor is a continuous transport device that uses a moving scraper chain within a closed rectangular cross-section shell to transport bulk materials. Because the scraper chain is completely submerged in the material during transport, it is called a scraper conveyor. Currently, scraper conveyors are widely used in coal mining faces, primarily for transporting materials in coal face and mining roadways. They can also be used in coal roadways and semi-coal-rock roadways, and can transport materials both upwards and downwards.

[0003] The central trough is a key component of large scraper conveyors in coal mines, serving as the channel for coal transportation. Figure 1 As shown, the central trough 100 is assembled and welded from components such as the shovel side 10, the baffle side 20, the middle plate 30, and the bottom plate 40. The middle plate 30 is installed and fixed between the two sides, dividing the space between the two sides into an upper trough and a lower trough. The upper trough is used for transporting coal, and the lower trough is used for the scraper chain return trip. In the production and welding process of the central trough 100, the shovel side 10, the baffle side 20, the middle plate 30, and the bottom plate 40 need to be welded and fixed to form a semi-finished product before the remaining components are welded. It can be seen that the positioning of the shovel side 10, the baffle side 20, the middle plate 30, and the bottom plate 40 is particularly important. However, in the current production of the central trough 100, multiple clamps are traditionally used for positioning. Multiple clamps require multiple welding operations, which is cumbersome and makes it difficult to effectively position the shovel side 10 and the baffle side 20, affecting the subsequent welding quality and welding accuracy.
