Abstract
Description
Technical Field
[0001] This utility model relates to the field of conveyor chains, and more particularly to a steel pipe conveyor chain with rollers. Background Technology
[0002] In domestic steel pipe manufacturing enterprises, steel pipe conveying is often involved. Traditional steel pipe conveying processes typically involve fixing the steel pipes onto a conveyor belt and conveying them synchronously. This type of conveyor belt has poor synchronization and is quite bumpy, making it easy for the steel pipes to slide relative to the conveyor belt, resulting in sliding friction between them. This can easily cause the steel pipes to be scratched and also reduces conveying efficiency. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model provides a steel pipe conveyor chain with rollers, which offers good stability and prevents the steel pipe from being scratched.
[0004] To achieve the above objectives, the present invention provides the following technical solution:
[0005] A steel pipe conveyor chain with rollers, characterized in that it includes interconnected inner and outer chain links, wherein the outer chain links are divided into connecting chain links and supporting chain links;
[0006] The outer link includes two outer link plates and a pin shaft disposed between the two outer link plates. The outer link plates in the support type link are raised and connected to a top roller for supporting the steel pipe.
[0007] The pin shaft described in part is extended, with both ends of the extended pin shaft protruding outside the conveyor chain and connected to guide rollers.
[0008] Preferably, the inner link includes a sleeve fitted outside the pin, a roller fitted outside the sleeve, and an inner link plate connected to the pins of two adjacent outer links.
[0009] Preferably, the connecting links and supporting links are alternately distributed.
[0010] Preferably, each set of supporting chain links has at least two top rollers, which are arranged along the extension direction of the conveyor chain.
[0011] Preferably, a grease layer is applied between the pin and the sleeve, and between the sleeve and the roller.
[0012] The advantages of this utility model are:
[0013] 1. During use, the guide rollers on both sides of the conveyor chain can be fitted into the guide rail to avoid the problem of the conveyor chain shaking and maintain the smoothness of the conveyor chain during transmission, so as to stably transmit the steel pipe.
[0014] 2. The top roller at the top of the support-type chain link is used to support and transport the steel pipe, changing the contact between the steel pipe and the conveyor chain from sliding friction to rolling friction, improving the transport efficiency, and at the same time preventing the steel pipe from being scratched.

[0019] Combination Figures 1 to 4 The present invention provides a further description of the steel pipe conveyor chain with rollers.
[0020] A steel pipe conveyor chain with rollers, characterized in that it includes alternating inner links 2 and outer links 1, wherein each outer link 1 includes two outer link plates 11 and a pin 12 disposed between the two outer link plates 11. The outer link 1 is distinguished by the shape and function of the outer link plates 11, and is divided into connecting links 5 and supporting links 6, as shown in the example. Figure 4 As shown, in the outer link 1 of the entire conveyor chain, connecting links 5 and supporting links 6 are alternately distributed.
[0021] The outer link plate 11 of the connecting link 5 has a monolithic structure, which is a rectangle with two semicircles. The outer link plate 11 of the supporting link 6 is raised by 111 on the basis of the monolithic structure to form an isosceles trapezoidal structure, and a top roller 4 for supporting the steel pipe is connected at the top. The four corners of the isosceles trapezoidal structure are all rounded.
[0022] like Figure 1 , 2 As shown, the inner link 2 includes a sleeve 23 sleeved outside the pin 12, a roller 22 sleeved outside the sleeve 23, and two inner link plates 21 connected to the pins 12 of two adjacent outer links 1.
[0023] The pin 12 described herein is extended by setting 121, with both ends of the extended pin 12 protruding outside the conveyor chain and connected to guide rollers 3. In this embodiment, the pin 12 is extended by setting 121 and the guide rollers 3 are added at regular intervals to ensure stable conveying of the conveyor chain. Specifically, the corresponding pin 12 is extended by setting 121 every three pins 12.
[0024] To increase the stability of the top roller 4 supporting the steel pipe, each set of supporting chain links 6 has at least two top rollers 4, which are arranged along the extension direction of the conveyor chain.
[0025] To improve the lubrication between the pin 12, sleeve 23 and roller 22, a grease layer is applied between the pin 12 and sleeve 23 and between sleeve 23 and roller 22.
[0026] In practical use, the top roller 4 at the top of the supporting chain link 6 is used to support and transport the steel pipe, changing the contact between the steel pipe and the conveying chain from sliding friction to rolling friction, improving the transport efficiency, and preventing the steel pipe from being scratched. Secondly, the guide rollers 3 on both sides of the conveying chain can be arranged in the guide rails on both sides of the conveying chain to avoid the problem of the conveying chain shaking and maintaining the smoothness of the conveying chain during transport, improving the stability of the steel pipe on the top roller 4, and thus transporting the steel pipe stably and efficiently.
