Abstract
The invention relates to the field of compact chains for mines, in particular to a four-gear type reinforced compact chain vertical ring. Four keep off formula strenghthened type compact chain and found ring be equipped with two convex dogs to the inboard respectively on two straight arms of standing the ring, upper and lower dog bisymmetry, after adding the dog, found ring shoulder neck inboard by straight arm (square cross section) to the sudden change optimization of top (circular cross section) for the circular arc transition, reduced stress concentration's appearance, changed the mechanical properties who found the ring, strengthened the rigidity and the intensity of its shoulder neck, reduced its probability of breaking, promoted the life of chain. Meanwhile, the four-gear reinforced compact chain vertical ring effectively prevents the flat ring from moving to the inner center of the vertical ring, so that the flat ring can freely rotate in a small angle range all the time, and the problem of twisting is indirectly solved.
Description
Technical Field
The invention relates to the field of compact chains for mines, in particular to a four-gear type reinforced compact chain vertical ring.
Background
In the use process of the mining compact chain, the load is complex and changeable, and the cross section of the inner side of the vertical ring shoulder neck is changed from the square of a straight arm part to the round of the top part, so that stress concentration is easily generated at the position, and the chain becomes one of the weak point and the main fracture source.
Disclosure of Invention
The invention aims to: in order to improve the stress condition of the compact chain vertical ring, enhance the mechanical property and rigidity of the compact chain vertical ring, prolong the service life of the compact chain vertical ring and indirectly solve the problem of twisting prevention, the invention provides a four-gear type reinforced compact chain vertical ring.
The purpose of the invention is realized by the following technical scheme: the inner side of the shoulder neck part 4 of the four-step reinforced compact chain vertical ring 6 is suddenly changed from a circular section of the top part 5 to a rectangular section of the straight arm 2, stress concentration is easy to generate, a baffle block 1 is arranged for improving the mechanical property of the four-step reinforced compact chain vertical ring, the baffle block 1 is generally T-shaped, protrudes towards the inner side of the vertical ring 6, and is symmetrical up and down pairwise. The flat ring 7 and the vertical ring 6 are installed in a matching mode, and the gap 3 of the symmetrical stop block 1 is smaller than the diameter of the flat ring 7. Meanwhile, a rotating space of the flat ring 7 is reserved between the top part 5 and the stop block 1.
The invention has the following beneficial effects: the mechanical property of the vertical ring is improved, the rigidity and the strength of the shoulder and neck parts of the vertical ring are enhanced, the breakage probability of the vertical ring is reduced, and the service life of the chain is prolonged. Meanwhile, the four-gear reinforced compact chain vertical ring effectively prevents the flat ring from moving towards the inner center of the vertical ring, so that the flat ring can freely rotate in a small-angle range all the time, and the problem of twisting is indirectly solved.
Description of the drawings:
the accompanying drawings, which are included to provide a further understanding of the invention, illustrate embodiments of the invention and together with the description serve to explain the invention and are not to limit the invention. In the drawings:
FIG. 1 is a schematic view of the structure of the vertical ring of the present invention
FIG. 2 is a schematic view of a compact chain of the prior art
In fig. 1-2: 1. Stop block, 2, straight arm, 3, gap, 4, shoulder and neck, 5, top, 6, vertical ring, 7, flat ring.
The specific implementation mode is as follows:
the embodiments of the invention will be further described with reference to the accompanying drawings in which:
as shown in fig. 1-2, the invention provides a four-stop reinforced compact chain vertical ring, wherein a stopper 1 protruding towards the inner side of the vertical ring 6 is arranged at the shoulder neck part of the vertical ring 6, and the stopper 1 is generally in a T shape and is symmetrical up and down two by two.
Specifically, in order to improve the mechanical property of the inner side of the shoulder and neck part of the vertical ring 6 and avoid stress concentration, the shoulder and neck part 4 of the four-step reinforced compact chain vertical ring 6 is provided with the vertically symmetrical stop blocks 1 protruding towards the inner side of the vertical ring 6, and the inner side of the shoulder and neck part of the vertical ring is optimized into arc transition from the section mutation of the straight arm 2 to the section mutation of the top part 5, so that the rigidity and the strength of the shoulder and neck part are enhanced, and the mechanical property of the shoulder and neck part is improved.
The flat ring 7 and the vertical ring 6 are installed in a matched mode, the gap 3 between the symmetrical stop blocks 1 is smaller than the diameter of the flat ring 7, the flat ring 7 is effectively prevented from moving towards the center of the inner side of the vertical ring 6, the flat ring 7 can freely rotate in a small-angle range all the time, and therefore the problem of twisting is indirectly solved.
The present embodiment should not be construed as limiting the present invention, but any modification made based on the spirit of the present invention should be within the scope of protection of the present invention.
