Description

Traction collapsible chains are known, consisting of shaped links of the same shape in the form of eights with locking projections at the ends, which are interconnected by rollers with two heads. However, such chains do not have sufficient reliability of locking joints and are rather difficult to manufacture.

These deficiencies are largely eliminated in the proposed split chain, consisting of two elements.

FIG. 1 shows a chain, side view; in fig. 2 - the same in terms of.

The chain is assembled from shaped links — plates J and fingers 2. Each plate with two figured holes 3 has the shape of a symmetric figure eight with one flat side. On the second side of the plate, two end 4 and two diagonal 5 protrusions are placed, which close the circuit after its assembly. The chain finger has a cylindrical body with two heads of 6 ellipsoid shapes.

For assembling the chain, at first two links are taken — plates and folded — with flat sides and protrusions outwards.

The fingers are inserted into the shaped holes of the plates, and two other plates are put on their heads on the heads, which are placed at right angles to the first plates. When the outer plates are rotated in line with the first plates, the heads of the fingers are placed between the projections of the outer plates.

This is how the chain of the desired length is assembled. The chain is disassembled in reverse order.

Subject invention

A folding chain, for example for scraper conveyors, consisting of shaped links of the same shape in the form of eights with locking protrusions at the ends, interconnected by rollers

with two heads, characterized in that, in order to increase the reliability of the locking connection and simplify the production of chains, its links are provided with locking middle diagonal protrusions, and the heads of the rollers interacting with the locking lobes of the links are made elliptical.
