Embodiment Construction

[0015] Figure 1-4 Among them, the mine-used flat chain with double straight arms of special-shaped cross-section includes welded flat rings of circular cross-section arranged at intervals, and a long chain structure is connected by a double straight arm with forged vertical ring of special-shaped cross-section. by comparison( image 3 , Figure 4 ), the cross-section of the straight arms on both sides of the vertical ring of the ordinary flat mining chain is symmetrical and the same, and the double straight arms are the double straight arms of the vertical ring of the mining flat chain with special-shaped cross-section, h2-h1≥3mm, m1-m2≥3mm. The cross-sectional areas of the straight arms on both sides can be equal or unequal. This provides a basis for the differentiated processing of the chain in the later stage.

Abstract

The invention relates to the technical field of mining chains, in particular to a double-straight-arm special-section mining flat chain. The mining flat chain with double straight arms of special-shaped sections comprises circular section welding flat rings which are arranged at intervals, and the circular section welding flat rings are connected into a long chain structure through a forging vertical ring with the double straight arms of the special-shaped sections. According to the forging vertical ring with the double straight arms of the special-shaped sections, the height of a chain can bereduced through differential design of the shapes of the sections of the double straight arms, the diameter of the flat ring is not changed, and the outer width of the vertical ring is remarkably reduced. The sectional area of the chain can be increased without changing the height of the chain. Therefore, the mechanical property parameters of the mining chain are greatly increased.

Description

technical field [0001] The invention relates to the structural design field of a flat chain for mining. Specifically, the purpose of the present invention is to reduce the outer width of the flat chain for mine service. Background technique [0002] These chains are used in the underground coal mining industry as conveyor chains for driving scraper conveyors. This type of scraper conveyor or chain scraper conveyor can consist of two motor-driven endless conveyor chains on which a scraper connected to the chain is fixed between the two chains. Conveying stripped material, such as coal, by means of scrapers. [0003] In the process of using a higher power driving device for the scraper machine, the load bearing requirements of the transmission chain are correspondingly increased, and only a chain with a larger cross-sectional area can be used. At the same time, the working space in the actual working conditions is relatively narrow, which can only ensure that the height of ...
