Problems solved by technology

Also, since the plow guide sections do not sit perfectly flush with each other during underground use, but constantly bend differently relative to each other, there is no way to avoid the chain connectors being in relation to other levels in the plow chain. Or the vertical links are overstretched, and even need to use the chain channel to determine the size of the chain linker
Therefore, the service life of the chain connector is shorter than that of hitherto known horizontal and vertical connections

Embodiment Construction

[0025] Figures 1A and 1B schematically show a combined chain link 10 in side view and plan view, respectively, with the same first link 1 and second link 2, and the first link 1 and the second link The connecting parts 2 are locked in a mirror-inverted manner, and the combined chain link 10 each includes two connecting link arcs 3 , outer legs 4 and inner legs 5 . The outer leg 4 of the chain link 1, 2 has at least two fixed teeth 7, 8, which cooperate with the locking protrusions 9, 11 on the inner leg 5 of the other corresponding chain link 2, for connecting the two The two chain connecting parts 1, 2 are locked together in a stretch-resistant manner. The splitting or locking plane on the chain link 10 thus lies in the leg formed by its outer leg 4 and inner leg 5 . The locked state of the chain link 10 shown in FIGS. 1A and 1B is by means of the locking element (14, image 3 ) is maintained, said locking element cooperates with the cylindrical receiving portion 13 on the i...

Abstract

The invention relates to a plane chain strand (50) provided with horizontal and vertical normal chain links (30, 40) which are mounted in an alternating manner and which engage into each other in a nondetachable manner with the limbs and arcs thereof. In the chain strand (50), directly in front and directly behind a chain lock link (10), at least one special chain link (20) is mounted in the same position as said chain locking link (10). The limbs of the lock links have the same outer contour, especially the same width and thickness, as the outer limbs of the two lock parts of the chain lock link (10). The wear and tear of the chain lock link (10) of said inventive plane chain strand (50) can be reduced or eliminated in comparison with conventional plane chains, by means of equal or slightly larger previous and subsequent special chain links (20).

Description

technical field [0001] The present invention relates to a plough chain strand with horizontal and vertical links, the link legs of which are connected by means of link arcs and in a Alternately intermeshing in a non-detachable manner, the plow chain also has a chain link for connecting the two chain ends, the chain link consisting of two chain links which are held together by a tensile Way lock together, there are split and lock planes at the legs. Background technique [0002] As is well known, plow chains consist of integral circular circular links each comprising parallel spaced apart link legs connected via link arcs. In a flat chain cable, the vertical chain links are respectively engaged in the oval inner openings between the chain link legs and the chain link arcs on the horizontal chain links by means of their chain link arcs, and hundreds of chain links Alternately and non-detachably superimposed on each other. Utilizing the plow chain, an underground mining plow...
