Description

Technical Field

[0001] The utility model relates to the technical field of tank chains, in particular to an upper-mounted tank chain. Background Art

[0002] The photoelectric switch signal lines in the tank chain have the important task of transmitting key signals, but they often face severe challenges in complex industrial production environments. When the tank chain is frequently extended and bent, the internal photoelectric switch signal lines will experience constant bending and twisting.

[0003] This continuous mechanical stress can cause the outer skin of the signal line to wear out, and the metal wire inside may be exposed and damaged. Once the signal line is broken, the entire photoelectric switch system will fail, causing the machines and equipment on the production line to not work properly. This will not only affect the production schedule, but may also cause product quality problems and even lead to safety accidents.

[0004] For production lines that rely on photoelectric switches for automated control, the stability and reliability of signal lines are crucial. Any unexpected circuit breakage may cause the production line to shut down, which in turn increases production costs and delays in delivery. Therefore, ensuring the safe use of the photoelectric switch signal line in the tank chain and reducing the problem of wear and circuit breakage caused by repeated bending actions have become important issues that need to be solved in industrial production. Utility Model Content

[0005] The utility model aims to solve one of the technical problems in the related art at least to a certain extent.

[0006] To this end, the purpose of the utility model is to propose an upper tank chain, in which a tension spring is added inside the tank chain, which can automatically adjust the tension according to the telescopic action of the tank chain to ensure that the signal line will not be excessively stretched or compressed when bending. This adaptive tension control mechanism significantly reduces the friction between the signal line and other components inside the tank chain, thereby greatly reducing the risk of signal line wear, which not only improves the service life of the signal line, but also enhances the reliability and stability of the entire system.

[0007] To achieve the above-mentioned purpose, the utility model proposes an upper tank chain including two main frames, two chain devices and two rotating devices, wherein the two chain devices each include a chain assembly, wherein the chain assemblies are rotatably arranged on the outer sides of the two main frames respectively; the two rotating devices each include a rotating wheel assembly and a gear assembly, wherein the rotating wheel assemblies are rotatably arranged at the bottom of the two main frames respectively, and the rotating wheel assemblies are movably connected to the inner walls of the chain assemblies; the gear assemblies are rotatably arranged on both sides of the two main frames respectively, and the gear assemblies are respectively meshed with the inner walls of the chain assemblies.

[0008] The utility model discloses an upper-mounted tank chain with a tension spring installed inside the tank chain, which can automatically adjust the tension according to the extension and retraction action of the tank chain to ensure that the signal line will not be excessively stretched or compressed when bending. This adaptive tension control mechanism significantly reduces the friction between the signal line and other components inside the tank chain, thereby greatly reducing the risk of signal line wear, which not only improves the service life of the signal line, but also enhances the reliability and stability of the entire system.

[0009] In addition, the above-mentioned upper tank chain proposed in the application may also have the following additional technical features:

On the contrary, the embodiments of the present invention include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0021] An upper tank chain according to an embodiment of the utility model will be described below in conjunction with the accompanying drawings.

[0022] like Figure 1-Figure 3 As shown, an upper tank chain of an embodiment of the utility model comprises two main frames (1), two chain devices (2) and two rotating devices (3), wherein the two chain devices (2) each comprise a chain assembly (21), wherein the chain assembly (21) is rotatably arranged around the outer sides of the two main frames (1), and the two rotating devices (3) each comprise a rotating wheel assembly (31) and a gear assembly (32), wherein the rotating wheel assembly (31) is rotatably arranged at the bottom of the two main frames (1), and the rotating wheel assembly (31) is movably connected to the inner wall of the chain assembly (21), and the gear assembly (32) is rotatably arranged on both sides of the two main frames (1), and the gear assembly (32) is meshed with the inner wall of the chain assembly (21).

[0023] It can be understood that the two main frames (1) drive the wheel assembly 31 and the gear assembly 32 to rotate. When the wheel assembly 31 and the gear assembly 32 rotate, the chain assembly 21 is driven to rotate, so the rotation of the chain assembly 21 can be realized. At the same time, the rotation of the wheel assembly 31 and the gear assembly 32 cooperates with the rotation of the chain assembly 21 to ensure stability during the rotation process, and no jamming will occur during long-term rotation operation.

[0024] In one embodiment of the present invention, Figure 1 and Figure 3 As shown, the chain assembly (21) comprises a chain (211) and a tension spring (212), wherein the chain (211) is rotatably arranged around the outer sides of the two main frames (1), and the tension spring (212) is arranged on the chain (211).

[0025] It can be understood that the tension spring (212) can automatically adjust the tension according to the extension and retraction action of the tank chain, ensuring that the signal line will not be excessively stretched or compressed when bending, and can reduce the friction between the signal line and other components inside the tank chain, thereby greatly reducing the risk of wear of the signal line.

[0026] In one embodiment of the present invention, Figure 2 As shown, the rotating wheel assembly (31) comprises a plurality of rotating wheels (311), wherein the plurality of rotating wheels (311) are rotatably arranged at the bottom of the two main frames (1), and the plurality of rotating wheels (311) are movably connected to the inner wall of the chain (211).

[0027] It can be understood that the rotation of multiple rotating wheels 311 can ensure stability during the rotation operation.

[0028] In one embodiment of the present invention, Figure 2 As shown, the gear assembly (32) comprises a rotating wheel (321) and a gear (322), wherein the rotating wheel (321) is rotatably arranged on one side of the two main frames (1), the rotating wheel (321) is movably connected to the inner wall of the chain (211), and the gear (322) is rotatably arranged on the other side of the two main frames (1), and the gear (322) is meshed with the inner wall of the chain (211).

[0029] It can be understood that the meshing rotation of the gear 322 on the chain 211 can drive the chain 211 to rotate, and at the same time, the synchronous rotation of the rotating wheel 321 on the chain 211 and the synchronous rotation of multiple rotating wheels 311 on the chain 211 can ensure the stability of the device during operation.

[0030] In one embodiment of the present invention, Figure 1 As shown, the two main frames (1) are connected to an external controller.

[0031] It can be understood that by connecting with an external controller, the rotation of the rotating wheel 321 and the gear 322 can be driven.

[0032] It should be noted that the control method of the present application can be automatically controlled by a controller, and the control method of the controller can be implemented by simple programming by technicians in this field, which is common knowledge in this field, and the present application is mainly used to protect mechanical structures, so the present application will no longer explain the control method and circuit connection in detail.

[0033] In summary, an upper tank chain in an embodiment of the utility model has a tension spring installed inside the tank chain, which can automatically adjust the tension according to the extension and retraction movement of the tank chain to ensure that the signal line will not be excessively stretched or compressed when bending. This adaptive tension control mechanism significantly reduces the friction between the signal line and other components inside the tank chain, thereby greatly reducing the risk of signal line wear, which not only improves the service life of the signal line, but also enhances the reliability and stability of the entire system.
