Abstract
The invention relates to the technical field of mining chains, in particular to a mining flat chain with double straight arms and special-shaped cross sections. The mining flat chain with the special-shaped cross section as the double straight arms comprises long chain structures which are connected by round cross section welding flat rings arranged at intervals and forged vertical rings with special-shaped cross sections as the double straight arms. The double straight arms are special-shaped section forging vertical rings, the height of the chain can be reduced through the differentiated design of the section shapes of the double straight arms, the diameter of the flat ring is unchanged, and the outer width of the vertical ring is obviously reduced. The sectional area of the chain can be increased when the height of the chain is unchanged. Thereby greatly increasing the mechanical performance parameters of the mining chain.
Description
Technical Field
The invention relates to the field of structural design of a mining flat chain. In particular, the invention aims to reduce the outer width of the flat chain for the clothing mine.
Background
Such chains are used in the underground coal mining industry as transmission chains for driving scraper conveyors. Such scraper or chain scraper conveyors can be formed by two endless motor-driven conveyor chains, on which the scraper connected to the chain between the two chains is fixed. The stripped material, such as coal, is conveyed by a scraper.
In the process that the scraper conveyor adopts a driving device with higher power, the requirement that the transmission chain bears load is correspondingly improved, and only the chain with larger sectional area can be adopted. Meanwhile, the working space is narrow under the actual working condition, and the height of the scraper conveyor can only be ensured to be small. Namely, the height of the transmission chain in the vertical direction is reduced as much as possible.
From the background art set forth above, it is known that a need exists for a transmission chain having a small outer width of the vertical links (standing rings) and a high tensile strength. At present, mining flat chains are mostly used, and the height of the vertical ring is reduced by forging the vertical ring.
Disclosure of Invention
The invention aims to further reduce the outer width of the vertical ring of the flat chain for mining. The new chain is a welding ring, and the vertical ring is a forging ring. Two straight arms of the vertical ring are designed in a differentiated mode, so that the height of the mining flat chain is reduced.
The technical scheme adopted by the invention for solving the technical problems is as follows: consists of a circular section welding flat ring 1 and a forging vertical ring 2 with a double straight arm with a special-shaped section; the round section welding flat rings 1 arranged at intervals are connected into a long chain structure through a double straight arm forging vertical ring 2 with a special-shaped section.
Furthermore, the double straight arms are the forged vertical ring 2 with the special-shaped cross section, the cross sections of the double straight arms are asymmetric and are different, h2-h1 is more than or equal to 3mm, and m1-m2 is more than or equal to 3 mm.
The mining flat chain has the beneficial effects that the height of the mining flat chain is further reduced, and meanwhile, the thickness (m) of a single-side straight arm entering the opening of the chain wheel is prevented from being increased. Not much interference to sprocket design. Under the condition of the same outer width of the vertical ring, the sectional area of the chain is larger, so that the overall mechanical performance of the chain is obviously improved.
Drawings
The invention is further illustrated with reference to the following figures and examples.
FIG. 1 is a schematic view of a mining flat chain with variable cross-sections of double straight arms
FIG. 2 is a schematic view of a flat chain for general mining
FIG. 3 is a schematic cross-sectional view of a vertical ring and a double straight arm forged by a flat chain for ordinary mining
FIG. 4 is a schematic view of a variable cross-section of a mining flat chain forging vertical ring with two straight arms as variable cross-sections
In the figure: 1. a flat ring; 2. and (5) standing the ring.
The specific implementation mode is as follows:
in fig. 1-4, the mining flat chain with the double straight arms having the special-shaped cross section includes long chain structures connected by a forged vertical ring with the double straight arms having the special-shaped cross section between the welded flat rings with the circular cross sections arranged at intervals. By comparison (figures 3 and 4), the sections of the straight arms on the two sides of the vertical ring of the ordinary flat mining chain are symmetrical and identical, the double straight arms are double straight arms of the vertical ring of the mining flat chain with the special-shaped section, h2-h1 is more than or equal to 3mm, and m1-m2 is more than or equal to 3 mm. The cross-sectional areas of the two side straight arms can be equal or unequal. Thereby providing a foundation for the differential processing of the chains in the later period.
