Abstract

The patent of the utility model discloses a bent compact chain that prevents knoing erects the ring, especially relates to the structural style that mining high strength compact chain found the ring. The utility model discloses mainly solve the chain and tie a knot and block the chain problem. The knotting and chain clamping are mainly caused by the fact that when the chain is in a free state, the horizontal ring and the vertical ring freely move and rotate mutually, and the vertical arm of the vertical ring is thick. The utility model discloses to erect the ring and add one "S" type dog in the middle of the straight arm inboard, make the flat ring be in all the time and found the less scope interval of ring thickness to solve and tie a knot, the card chain problem. The utility model discloses the structural style who founds ring both ends circular arc part has been changed to the mechanical properties who founds the ring has been strengthened.

Description

Curved knot-preventing compact chain vertical ring

Technical Field

The patent of the utility model discloses a bent compact chain that prevents knoing erects the ring, especially relates to the structural style that mining high strength compact chain found the ring.

Background

In modern automatic mechanical coal mining, a scraper conveyor and a reversed loader are used for working face transportation. And the main part for bearing power transmission and coal transportation is a chain. Limited by working environment, the flat and vertical rings of the current large-specification chain have different structures and sizes, and the outer width b2 of the vertical ring is smaller than the outer width b1 of the flat ring; the thickness c of the vertical ring is larger than the diameter d of the flat ring; this is a compact chain developed on the basis of the original round-link chain with completely identical flat and vertical rings, and the structural form of the compact chain is shown in figure 2. Compared with a round-link chain, the compact chain has the main advantages that the large-size compact chain can be used by using the chain channel of the round-link chain, so that the bearing capacity of the host is greatly enhanced, and the transport capacity is greatly improved. However, due to the change of the structure and the size, the phenomena of flat and vertical ring knotting and chain blocking often occur, and the zipper cannot be spread when the zipper is serious, so that the zipper cannot be used.

Disclosure of Invention

In order to solve the defect that prior art problem exists, the utility model provides a bent compact chain that prevents knoing erects the ring.

The utility model discloses a solve the technical scheme that technical problem adopted as follows:

the utility model discloses a compact chain that knots is prevented to bent formula founds ring especially relates to the structural style of mining high strength compact chain founds ring.

As an optimized technical scheme of the utility model, a bent compact chain that prevents knoing erects the ring, is inboard in the middle of founding the ring straight arm and adds an "S" type dog, makes the flat ring be in all the time and found the less scope interval of ring thickness, has guaranteed to tie, has founded to rotate freely between the ring to solve and tie a knot, card chain problem. Moreover, the S-shaped stop block plays a role in supporting the vertical arm of the vertical ring, and the rigidity of the vertical ring is increased.

As an optimized technical scheme of the utility model, a compact chain that knots is prevented to bent formula founds ring, and it has changed the structural style who founds ring both ends circular arc part to the mechanical properties who founds the ring has been strengthened.

The utility model discloses the beneficial effect who reaches is: firstly, the phenomena of knotting and chain blocking of the flat and vertical rings are solved; and secondly, the mechanical property of the vertical ring is enhanced.

Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.

Example 1

As shown in figure 2, an S-shaped stop block is additionally arranged on the inner side of the middle of the vertical arm of the vertical ring, so that the flat ring is always positioned in the range of the small thickness of the vertical ring, the flat ring and the vertical ring are ensured to freely rotate, and the problems of knotting and chain clamping are solved. Moreover, the S-shaped stop block plays a role in supporting the vertical arm of the vertical ring, and the rigidity of the vertical ring is increased.

As shown in figure 4, the utility model changes the structure pattern of the arc parts at the two ends of the vertical ring, thereby enhancing the mechanical performance of the vertical ring.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.

Claims

1. A bent anti-knotting compact chain vertical ring is characterized in that an S-shaped stop block is added on the inner side of the middle of a vertical arm of the vertical ring, so that a flat ring cannot move towards the other end, and the S-shaped stop block has a fixing effect on the swaying flat ring; moreover, the S-shaped stop block plays a role of supporting the vertical ring straight arm.

2. A curved knot-preventing compact standing chain ring as claimed in claim 1, wherein the cross section of the standing ring is a structure that the inner ring is circular and the outer ring is square.
