Description

Technical Field

[0001] The utility model relates to the field of chains, in particular to an integral chain link type top plate conveying chain. Background Art

[0002] Chain conveyor is a chain used to pull and carry materials for transportation. In addition to the common chain links and pin shaft structure, it is usually equipped with rollers to achieve load-bearing and rolling. In order to better achieve the conveying of loads, a top plate is often set in the conveyor chain.

[0003] For example, a Chinese invention patent application with application publication number CN 114084589 A discloses a dustproof top plate conveyor chain comprising a pin shaft, a welded inner chain link, a welded outer chain link, and an outer chain plate. Both ends of the pin shaft pass through the outer chain plate and are fitted with side rollers. Deep groove ball bearings are provided inside the two side rollers. The coordination between the dust cover of the chain bearing and the plastic dust cover, and the coordination between the shaft elastic retaining ring and the hole elastic retaining ring, can effectively seal the deep groove ball bearing, prevent dust from entering the interior of the bearing, ensure the normal operation of the bearing, and extend its service life. However, there are certain differences in the dimensions of the inner and outer chain links in the above-mentioned conveyor chain. They need to be processed separately during processing and then assembled into a chain. This results in a large number of parts and a complicated assembly process. Summary of the Invention

[0004] The technical problem to be solved by the utility model is to provide an integral chain link type top plate conveyor chain, which adopts an integral chain single link, and the structure and size of each chain link are completely consistent, which greatly reduces the types of parts and improves the processing and assembly efficiency.

[0005] In order to solve the above technical problems, the technical solution provided by the present invention is as follows: an integral chain link type top plate conveyor chain, comprising a plurality of chain single links, each chain single link is distributed in sequence and connected by a pin shaft, and the pin shaft is connected to a roller;

[0006] Each of the chain links includes a top plate and two chain plates, the two chain plates are arranged in parallel, and the top plate and the two chain plates are integrally formed; each of the chain plates includes a first connecting portion and a second connecting portion, and the first connecting portion and the second connecting portion are staggered along the thickness direction of the chain plate;

[0007] Between two adjacent chain links, the first connecting portion of the chain plate in the preceding chain link corresponds to the second connecting portion of the chain plate in the following chain link and are connected by a pin.

[0008] By setting the chain plate into a first connecting part and a second connecting part that are staggered, the connection between two adjacent chain links can be achieved without distinguishing between inner chain links and outer chain links. They can be directly connected in series in the form of chain links. The structure and size of each chain link are completely consistent, which greatly reduces the number of parts and improves processing and assembly efficiency.

[0009] Preferably, the top plate includes a main body, the edge of the main body is bent toward the side facing the pin shaft to form a edging, and the edging encloses a docking groove; the chain plate includes an inserting portion, and the inserting portion extends into the docking groove.

[0010] The hemming process can fully strengthen the top plate and improve its mechanical properties. On the basis of the same weight, it effectively increases the conveying capacity of the conveyor chain. At the same time, the hemming setting can also bend the edge of the top plate downward, preventing the edges from being affected by processing defects such as burrs and affecting the normal use of the conveyor chain.

[0011] Preferably, the chain plate and the top plate are integrally cast.

[0012] Preferably, the top plate includes a V-shaped portion and two straight portions along the axial direction of the pin shaft, the V-shaped portion is located between the two straight portions, the V-shaped opening of the V-shaped portion is set away from the pin shaft, and the chain plate is connected to the straight portion.

[0013] When conveying large materials with a flat contact surface, the straight section can better mate with the material's contact surface. Furthermore, connecting the straight section to the chain plate results in less sudden shape changes at the connection compared to connecting the V-shaped section directly to the chain plate, which can reduce stress concentration to a certain extent.

[0014] Preferably, the end of the pin passes through the chain plate and is connected to the roller via a rolling bearing at the end.

[0015] Preferably, the chain link further includes a sleeve, and the sleeve is integrally formed with the chain plate.

[0016] Preferably, in the same chain link, the first connecting parts of the two chain plates are arranged opposite to each other, and the second connecting parts of the two chain plates are arranged opposite to each other, the spacing between the two first connecting parts is greater than the spacing between the two second connecting parts, and an insertion interval is formed between the two first connecting parts; between two adjacent chain links, the second connecting part of the chain plate in the previous chain link is inserted into the insertion interval formed by the two first connecting parts in the next chain link.

[0024] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. Example

[0025] like Figure 1 and Figure 2 As shown, an integral chain link type top plate 11 conveying chain includes a plurality of chain links 1, each chain link 1 is distributed in sequence and connected by a pin shaft 2, and the pin shaft 2 is connected to a roller 3.

[0026] like Figures 4-6 As shown, each chain link 1 includes a top plate 11 and two chain plates 13. The two chain plates 13 are arranged in parallel. The top plate 11 and the two chain plates 13 are integrally formed. Specifically, the chain plates 13 and the top plate 11 are integrally cast. Specifically, the ends of the pins 2 pass through the chain plates 13 and are connected to the rollers 3 via rolling bearings. The chain link 1 also includes a sleeve 12, which is integrally formed with the chain plates 13.

[0027] like Figures 3-6 As shown, each link plate 13 includes a first connecting portion 131 and a second connecting portion 132, which are staggered along the thickness direction of the link plate 13. Between two adjacent chain links, the first connecting portion 131 of the link plate 13 in the preceding link corresponds to the second connecting portion 132 of the link plate 13 in the succeeding link, and are connected by a pin 2.

[0028] like Figures 3-6Specifically, within the same chain link, the first connecting portions 131 of the two chain plates 13 are disposed opposite each other, and the second connecting portions 132 of the two chain plates 13 are disposed opposite each other. The spacing between the two first connecting portions 131 is greater than the spacing between the two second connecting portions 132, forming an insertion space between the two first connecting portions 131. Between two adjacent chain links, the second connecting portion 132 of the chain plate 13 in the preceding chain link is inserted into the insertion space formed by the two first connecting portions 131 in the succeeding chain link.

[0029] By setting the chain plate 13 into a first connecting portion 131 and a second connecting portion 132 that are staggered, the connection between two adjacent chain links can be achieved without distinguishing between inner and outer chain links. They can be directly connected in series in the form of chain links 1. The structure and size of each chain link 1 are completely consistent, which greatly reduces the number of parts and improves processing and assembly efficiency.

[0030] Further, such as Figure 4 and Figure 7 As shown, the top plate 11 includes a main body 114, the edge of which is bent toward the side facing the pin 2 to form a rim 113. The rim 113 encloses a docking groove. The chain plate 13 includes a plug-in portion that extends into the docking groove. The formation of the rim 113 can comprehensively strengthen the top plate 11 on all sides, improving the mechanical properties of the top plate 11 and effectively increasing the conveying capacity of the conveyor chain at the same weight. At the same time, the provision of the rim 113 can also bend the edge of the top plate 11 downward, preventing processing defects such as burrs on the edge from affecting the normal use of the conveyor chain.

[0031] Furthermore, Figure 2 As shown, the top plate 11 includes a V-shaped portion 112 and two straight portions 111 along the axis of the pin 2. The V-shaped portion 112 is located between the two straight portions 111, with the V-shaped opening of the V-shaped portion 112 facing away from the pin 2. The chain plate 13 is connected to the straight portions 111. When conveying large materials with a flat contact surface, the straight portions 111 can better mate with the material's contact surface. Furthermore, the connection between the straight portions 111 and the chain plates 13 results in a smaller shape change at the connection than when the V-shaped portion 112 is directly connected to the chain plates 13, which can reduce stress concentration to a certain extent.

[0032] In short, the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
