Description

Technical Field

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

[0002] Chain conveyor is a chain used to pull and carry materials for conveying. In addition to the common chain link and pin structure, rollers are usually provided to achieve load-bearing and rolling. In order to better realize the conveying of loads, a top plate is often provided in the conveying chain. For example, the Chinese utility model patent with the authorization announcement number CN 219448164 U discloses a conveying 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 respectively, and rollers are connected to the two ends. The conveying chain in the above-mentioned existing patents has the advantages of simple load-bearing component structure and reliable structural stability, but it also has the problem of complicated processing procedures. 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 limits the use scenario to a certain extent. Summary of the invention

[0003] The technical problem to be solved by the present invention 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 as 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-bearing stability.

[0004] In order to solve the above technical problems, the technical solution provided by the present invention is as follows: an integrated top plate type top plate conveyor chain comprises 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 connected by a transition portion, the width of the transition portion is smaller than the width of the top plate; the chain link is arranged in one piece and is bent at the transition portion; The top plate comprises a V-shaped portion, a 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, and the guide line is arranged perpendicular to the axis of the pin shaft.

[0005] The chain links are set in an integrally formed form, which simplifies the processing steps and reduces the processing cost. 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. When the conveyed material is a bar, the V-shaped part can guide the bar to move to the center of the top plate, which plays a restraining role on the conveyed material.

[0006] Preferably, the edges of both sides of the top plate are bent toward the side facing the pin to form an edge. The edge forming can strengthen the top plate and improve the mechanical properties of the top plate, and effectively improve the conveying capacity of the conveyor chain on the basis of the same weight. At the same time, the edge setting can also bend the edge of the top plate downward to prevent the edge from affecting the normal use of the conveyor chain due to processing defects such as burrs.

[0007] Preferably, the top plate is provided with a plurality of reinforcement parts, and the reinforcement parts extend along the length direction of the top plate. The reinforcement parts can specifically strengthen the length direction of the top plate, and reduce the difference in mechanical properties of the top plate in the length direction and the width direction.

[0008] Preferably, the top plate is provided with at least one bend, and the fold of the bend forms a reinforcement portion.

[0009] Preferably, the top plate is provided with an inwardly recessed concave reinforcing rib, and the concave reinforcing rib is arranged at the center of a side of the top plate away from the pin shaft.

[0010] The concave reinforcement ribs can strengthen the center part of the top plate. Due to the structure of the top plate, the center part of the top plate is its structural weak point. By setting the concave reinforcement ribs, targeted reinforcement can be carried out to improve the overall mechanical properties of the top plate.

[0011] Preferably, the top plate further comprises two straight portions, the V-shaped portion is located between the two straight portions, and the straight portion is connected to the transition portion.

[0012] When the conveyed material is large in size and the contact surface is a plane, the straight portion can better cooperate with the contact surface of the material. In addition, the connection between the straight portion and the chain plate has a smaller shape mutation than the direct connection between the V-shaped portion and the chain plate, which can reduce the stress concentration to a certain extent.

[0013] Preferably, the pin shaft outer sleeve is provided with a sleeve.

[0014] 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.

[0015] Preferably, the pin shaft 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 shaft is fixedly connected to the outer link plate, and is rotationally connected to the inner link plate through a self-lubricating bearing; the inner side of the rolling bearing abuts against the outer link plate through a washer, and the outer side is locked and positioned with the pin shaft through a retaining ring.

[0016] Preferably, in each of the chain links, one of the chain plates is an inner chain plate, the other chain plate is an outer chain plate, and the length of the transition portion connected to the inner chain plate is shorter than the length of the transition portion connected to the outer chain plate; Between every two adjacent links, the guide lines of the V-shaped portion of the top plate are aligned, the inner link plate of the previous link and the outer link plate of the next link are located on the same side, and the corresponding outer link plate of the previous link and the inner link plate of the next link are located on the same side.

[0017] By setting the inner link plate and the outer link plate on the same chain plate at the same time, the connection between two adjacent chain links can be achieved without distinguishing between the inner link and the outer link. They can be directly connected in series in the form of chain links. The structure and size of each chain link are exactly the same, which greatly reduces the types of parts and improves the processing and assembly efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with 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

[0020] like Figure 1 and Figure 2As 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 shaft 2, a sleeve is provided on the outer sleeve of the pin shaft 2, and a roller is connected to the pin shaft 2.

[0021] like Figure 3-Figure 5 As shown, each of the chain links 1 comprises 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; 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 As shown, specifically, the top plate 11 further includes two straight portions 112, the V-shaped portion 111 is located between the two straight portions 112, and the straight portion 112 is connected to the transition portion 13. When the size of the conveyed material is large and the contact surface is a plane, the straight portion 112 can better cooperate with the contact surface of the material. In addition, the connection between the straight portion 112 and the chain plate 12 is smaller than the direct connection between the V-shaped portion 111 and the chain plate 12, and the stress concentration can be reduced to a certain extent.

[0023] Specifically, Figure 6 As shown, the chain link 1 includes an inner chain link 16 and an outer chain link 15, and the inner chain link 16 and the outer chain link 15 are alternately distributed. The chain plate 12 corresponding to the inner chain link 16 is an inner chain plate, and the chain plate 12 corresponding to the outer chain link 15 is an outer chain plate. The distance between the two inner chain plates in the inner chain link 16 is smaller than the distance between the two outer chain plates in the outer chain plate. The pin shaft 2 is arranged through the inner chain plate and the outer chain plate, and is connected to the roller at the end through a rolling bearing 31. The pin shaft 2 is fixedly connected to the outer chain plate, and is rotatably connected to the inner chain plate through a self-lubricating bearing 4. The inner side of the rolling bearing 31 abuts against the outer chain plate through a washer, and the outer side is locked and positioned with the pin shaft 2 through a snap ring.

[0024] The chain link 1 is provided in an integrally formed form, which simplifies the processing steps and reduces the processing cost. At the same time, the top plate 11 is completely placed between the two chain plates 12. When conveying materials, the load on the top plate 11 can also be better controlled between the two chain plates 12, greatly improving the load stability. When the conveyed material is a bar, the V-shaped portion 111 can guide the bar to move toward the center of the top plate 11, thereby constraining the conveyed material.

[0025] Further, such as Figure 3-Figure 5 As shown, the edges of both sides of the top plate 11 are bent toward the side facing the pin 2 to form a rim. The rim formation can strengthen the top plate 11, improve the mechanical properties of the top plate 11, and effectively improve the conveying capacity of the conveyor chain on the basis of the same weight. At the same time, the setting of the rim can also bend the edge of the top plate 11 downward to prevent the edge from affecting the normal use of the conveyor chain due to processing defects such as burrs.

[0026] Furthermore, the top plate 11 is provided with a plurality of reinforcement parts, and the reinforcement parts extend along the length direction of the top plate 11. The reinforcement parts can specifically reinforce the length direction of the top plate 11, and reduce the difference in mechanical properties between the length direction and the width direction of the top plate 11. The top plate 11 is provided with at least one bend, and the fold of the bend forms a reinforcement part.

[0027] Furthermore, Figure 3-Figure 5 As shown, the top plate 11 is provided with an inwardly concave reinforcing rib 14, and the concave reinforcing rib 14 is arranged at the center of the side of the top plate 11 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, targeted reinforcement can be performed to improve the overall mechanical properties of the top plate 11. Example

[0028] Compared with the first embodiment, the difference of this embodiment is that: Figure 7 and Figure 8 As shown, in each of the chain links 1, one of the chain plates 12 is an inner chain plate, and the other chain plate 12 is an outer chain plate. The length of the transition portion 13 connected to the inner chain plate is shorter than the length of the transition portion 13 connected to the outer chain plate. Figure 7 As shown in , the length of the transition portion 13 connected to the inner link plate is denoted as d, and the length of the transition portion 13 connected to the outer link plate is denoted as D, and D>d. Between every two adjacent links 1, the guide lines of the V-shaped portion 111 of the top plate 11 are aligned, the inner link plate of the preceding link 1 and the outer link plate of the succeeding link 1 are located on the same side, and the corresponding outer link plate of the preceding link 1 and the inner link plate of the succeeding link 1 are located on the same side.

[0029] By simultaneously arranging inner link plates and outer link plates on the same chain plate 12, it is possible to achieve connection between two adjacent chain links 1 without distinguishing between inner link and outer link. They can be directly connected in series in the form of chain single links. The structure and size of each chain single link are completely consistent, which greatly reduces the types of parts and improves processing and assembly efficiency.

[0030] 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 substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
