Description

Technical Field

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

[0002] A chain conveyor is a chain used to pull and carry materials for transportation. In addition to the common chain links and pin structures, rollers are usually provided to achieve load-bearing and rolling. In order to better achieve the transportation of loads, a top plate is often provided in the conveyor chain. For example, the Chinese utility model patent with the authorization announcement number CN 219448164 U discloses a conveyor chain for conveying metal profiles, including inner chain links and outer chain links. The outer chain links include a top plate and two outer chain plates. The inner chain links are located between the two outer chain plates. The two ends of the pin extend out of the corresponding outer chain plates, and rollers are connected to the two ends. The conveyor chain in the above-mentioned existing patents has the advantages of a simple load-bearing component structure and reliable structural stability, but it also has the problem of a relatively complicated processing procedure. In addition, due to the small spacing between the outer chain plates, the distance between the two sides of the top plate extending out of the outer chain plates is large, and the top plate is subjected to a large bending moment when loaded, which to a certain extent limits the use scenario. Summary of the Invention

[0003] The technical problem to be solved by the utility model is to provide an integrated top plate type top plate conveyor chain, which simplifies the processing procedure by bending the top plate and the chain plate into one piece. At the same time, the top plate is completely placed between the two chain plates. When conveying materials, the load on the top plate can also be better controlled between the two chain plates, greatly improving the load stability.

[0004] In order to solve the above technical problems, the technical solutions provided by the present invention are as follows: an integrated top plate type top plate conveyor chain, comprising a plurality of chain links, each of which is distributed in sequence and connected by a pin shaft, and a roller is connected to the pin shaft; each of the chain links comprises a top plate and two chain plates, the two chain plates are arranged in parallel, the top plate is located between the two chain plates, and the top plate and the chain plates are bent into one piece; the top plate comprises a V-shaped portion, the V-shaped opening of the V-shaped portion is arranged away from the pin shaft, and a guide line is formed at the bottom of the V-shaped opening, the guide line is arranged perpendicular to the axis of the pin shaft, and the chain links are opposite to each other on the left and right relative to the guide line.

[0005] The chain links are integrally formed, simplifying processing steps and reducing costs. The top plate is also positioned completely between the two chain plates, effectively controlling the load on the top plate during material conveying, significantly improving load stability. When conveying bar stock, the V-shaped portion guides the bar toward the center of the top plate, providing a restraining force on the material being conveyed.

[0006] Preferably, both side edges of the upper surface of the top plate are provided with rounded corners.

[0007] Preferably, a plurality of reinforcement parts are distributed on the top plate, and the reinforcement parts extend along the length direction of the top plate.

[0008] The reinforcement portion can specifically strengthen the length direction of the top plate, thereby reducing the difference in mechanical properties of the top plate in the length direction and the width direction.

[0009] Preferably, the chain links include inner chain links and outer chain links, and the inner chain links and outer chain links are distributed alternately; wherein the chain plates corresponding to the inner chain links are inner chain plates, and the chain plates corresponding to the outer chain links are outer chain plates, and the spacing between the two inner chain plates in the inner chain links is smaller than the spacing between the two outer chain plates in the outer chain plates.

[0010] Preferably, the pin is arranged through the inner link plate and the outer link plate, and is connected to the roller at the end through a rolling bearing; the pin is fixedly connected to the outer link plate and is rotationally connected to the inner link plate through a self-lubricating bearing.

[0011] Preferably, the inner side of the rolling bearing abuts against the outer link plate via a washer, and the outer side is locked and positioned with the pin via a snap ring. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] 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

[0019] like Figure 1 and Figure 2 As shown, the integrated top plate 11 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 2, the pin 2 is outerly provided with a sleeve, and the pin 2 is connected to a roller.

[0020] like Figure 3-Figure 5 As shown, each of the chain links 1 includes a top plate 11 and two chain plates 12, and the two chain plates 12 are arranged in parallel; the top plate 11 is located between the two chain plates 12 and connected by a transition portion 13, and the width of the transition portion 13 is smaller than the width of the top plate 11; the chain link 1 is arranged in one piece and is bent at the transition portion 13;

[0021] like Figure 3-Figure 5 As shown, the top plate 11 includes a V-shaped portion 111 , a V-shaped opening of the V-shaped portion 111 is arranged away from the pin shaft 2 , and a guide line is formed at the bottom of the V-shaped opening, and the guide line is arranged perpendicular to the axis of the pin shaft 2 .

[0022] like Figure 3-Figure 5 Specifically, the top plate 11 further includes two straight portions 112, with the V-shaped portion 111 positioned between the two straight portions 112. The straight portions 112 connect to the transition portion 13. When conveying large materials with a flat contact surface, the straight portions 112 can better mate with the material's contact surface. Furthermore, the connection between the straight portions 112 and the chain plates 12 results in less sudden shape changes at the connection compared to direct connection of the V-shaped portion 111 to the chain plates 12, which can reduce stress concentration to a certain extent.

[0023] Specifically, such as Figure 6 As shown, the chain link 1 includes inner links 16 and outer links 15, which are arranged alternately. The chain plates 12 corresponding to the inner links 16 are inner chain plates, while the chain plates 12 corresponding to the outer links 15 are outer chain plates. The spacing between the two inner chain plates in the inner link 16 is smaller than the spacing between the two outer chain plates in the outer chain. The pin 2 is disposed through the inner and outer chain plates and connected to a roller at its end via a rolling bearing 31. The pin 2 is fixedly connected to the outer chain plate and rotatably connected to the inner chain plate via a self-lubricating bearing 4. The inner side of the rolling bearing 31 abuts against the outer chain plate via a washer, and the outer side is locked in place with the pin 2 via a retaining ring.

[0024] The chain link 1 is integrally formed, simplifying manufacturing steps and reducing costs. It also positions the top plate 11 completely between the two chain plates 12. During material conveying, the load on the top plate 11 is better controlled between the two chain plates 12, significantly improving load stability. When conveying bar stock, the V-shaped portion 111 guides the bar toward the center of the top plate 11, constraining the material being conveyed.

[0025] Further, such as Figure 3-Figure 5 As shown, the edges of the top plate 11 are bent toward the side facing the pin 2 to form a hemming. This hemming strengthens the top plate 11 and improves its mechanical properties, effectively increasing the conveying capacity of the conveyor chain at the same weight. Furthermore, the hemming also bends the edges of the top plate 11 downward, preventing machining defects such as burrs from affecting the normal operation of the conveyor chain.

[0026] Furthermore, the top plate 11 is provided with a plurality of reinforcements extending along the length of the top plate 11. These reinforcements provide targeted reinforcement along the length of the top plate 11, reducing the difference in mechanical properties between the length and width of the top plate 11. The top plate 11 is provided with at least one bend, with the reinforcement formed at the crease of the bend.

[0027] Furthermore, Figure 3-Figure 5 As shown, the top plate 11 is provided with an inwardly concave reinforcing rib 14, which is located at the center of the side of the top plate 11 facing away from the pin 2. The concave reinforcing rib 14 can strengthen the center of the top plate 11. Due to the structure of the top plate 11, the center of the top plate 11 is its structural weak point. By providing the concave reinforcing rib 14, it can be targeted and reinforced, thereby improving the overall mechanical properties of the top plate 11.

[0028] 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.
