[0019] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific implementation methods described here are only used to explain the utility model and do not limit the protection scope of the utility model.
[0020] It should be noted that when an element is referred to as being "fixed to", "disposed on", "fixed on" or "installed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. Further, when an element is considered to be "fixedly connected to" another element, the two may be fixed in a detachable connection manner or in a non-detachable connection manner, such as socketing, snap-on, one-piece fixation, welding, etc., which can be achieved in the prior art and will not be repeated here. When an element is perpendicular or approximately perpendicular to another element, it means that the ideal state of the two is vertical, but due to the influence of manufacturing and assembly, there may be a certain vertical error. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.
[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.
[0022] The “first” and “second” involved in the present utility model do not represent specific quantities and orders, but are merely used to distinguish names.
[0023] Combined with Figure 1 The present embodiment is a dummy chain with an auxiliary chain added between two chain rows, comprising two rows of main chains 1 and one row of auxiliary chains 2, wherein the auxiliary chains 2 are arranged between the two rows of main chains 1, and the main chains 1 and the auxiliary chains 2 are both extended in the same direction, and further comprising a plurality of long pins 3, wherein the movable joints are the connection positions of the inner and outer chain links of the main chains 1 and the auxiliary chains 2, and the long pins 3 are arranged along the arrangement direction of the main chains 1 and the auxiliary chains 2 and simultaneously connect the movable joints of the main chains 1 and the auxiliary chains 2.
[0024] The ingot guide chain with an auxiliary chain added between the two chain rows solves the working principle of the ingot guide chain: in the continuous steel casting process, the upward bending and downward winding of the ingot guide chain will cause its structural instability during the walking process. When the above-mentioned unstable condition suddenly changes, it will cause the ingot guide chain to stop walking, which will directly cause the liquid level of the molten steel being pulled to fluctuate greatly in the crystallizer, thereby causing the molten steel to be scrapped due to excessive liquid level fluctuations. An auxiliary chain is added between the two chain rows, and a long pin shaft connects the two rows of main chains, so that the two rows of main chains are synchronously and evenly stressed at all locations, preventing downward deflection and left and right lateral bending, effectively improving the forming quality of continuous steel casting and improving production efficiency. At the same time, the auxiliary chain will also share part of the pulling force, further preventing upward bending, downward winding and lateral bending due to uneven force, and also improving the strength of the chain and extending the service life of the chain.
[0025] The ingot drawing chain with an auxiliary chain added between the two chain rows solves various problems that may occur in the ingot drawing chain during continuous steel casting. The auxiliary chain connects the two rows of main chains through a long pin shaft to prevent the chain from bending and bending to the left and right sides, effectively improving the forming quality of continuous steel casting and improving production efficiency. The auxiliary chain will also share part of the pulling force, further improving the strength of the chain, effectively extending the service life of the chain, and comprehensively improving the quality of the chain.
[0026] As a preferred embodiment of the present utility model, the main chain 1 includes a plurality of first inner links 11 and first outer links 12 which are alternately connected in sequence. The first outer links 12 are first outer link plates respectively arranged on both sides of the first inner links 11. The first inner links 11 and the first outer links 12 are movably connected through a long pin shaft 3, and a first sleeve 13 is arranged in a chain plate hole on the first inner link 11 corresponding to the chain pitch.
[0027] As a preferred embodiment of the utility model, the auxiliary chain 2 includes a plurality of second inner links 21 and second outer links 22 which are connected alternately in sequence. The second outer links 22 are second outer link plates respectively arranged on both sides of the second inner links 21. The second inner links 21 and the second outer links 22 are movably connected through a long pin shaft 3, and a second sleeve 23 is arranged in the chain plate hole corresponding to the chain pitch on the second inner link 21, and the first sleeve 13 and the second sleeve 23 are coaxially arranged.
[0028] As a preferred embodiment of the utility model, the first inner link 11 and the first outer link 12 are matched through a anti-bending structure. In this embodiment, the anti-bending structure includes a anti-bending pin 4, which is inserted and connected to the first inner link 11, and both ends of the anti-bending pin 4 extend from the side of the first inner link 11; a stop block 5, which is connected to the first outer link 12. The stop block 5 is symmetrically arranged on both sides of the first inner link 11, and when the ingot chain is straightened, the stop block 5 abuts against the lower end of the stop pin 4; when the first inner link 11 has a tendency to bend sideways relative to the first outer link 12, the abutment between the stop pin 4 and the stop block 5 can suppress the lateral bending phenomenon, thereby improving the lateral bending strength of the main chain 1 itself.
[0029] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
