Description

Technical Field

[0001] The utility model relates to the technical field of plate chains, in particular to a high-strength improved plate chain. Background Art

[0002] When the existing plate chain is working under heavy load, low speed and high strength, due to the impact and friction between the chain and the sprocket, the company previously designed a plate chain (CN206478167U), which has a longer service life than the existing plate chain during use. Its internal position cooperating with the pin only adopts a perforated structure, and its cooperation smoothness during use is relatively poor, and its wear resistance during use is also relatively poor. The bearing capacity of the overall structure is limited and cannot meet the use requirements in an application environment with relatively high strength requirements. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a high-strength improved plate chain, which improves the structure of the existing plate chain. By arranging a sleeve structure between the internal intermediate plates, it ensures better smoothness of the cooperation between the internal structure and the pin during use, and stronger wear resistance of the overall moving components during use. Its outer side is provided with a double-layer outer chain plate structure, and a welded cooperation groove is arranged between the outer chain plate and the pin, which can ensure higher overall strength at the connection position, stronger bearing capacity during use, and effectively improve the use safety, so as to meet the use requirements in an application environment with relatively high strength requirements.

[0004] The technical solution of the utility model is as follows:

[0005] A high-strength improved plate chain includes an intermediate isolation and support chain plate. Inner chain plate structures are respectively arranged on both sides of the intermediate isolation and support chain plate. An outer chain plate structure is arranged on the outer side of the inner chain plate structure. A sleeve structure is arranged inside the inner chain plate structure. The inside of the sleeve structure is combined with the outer chain plate structure through a pin. The outer chain plate structure consists of two superimposed outer connecting plates. The inner chain plate structure consists of three superimposed inner connecting plates. It is characterized in that: the intermediate isolation and support chain plate consists of two superimposed intermediate connecting plates. A transition smooth sleeve is arranged at the position where the inside of the intermediate isolation and support chain plate cooperates with the pin. The cross-section of the outer side of the pin at the position where it cooperates with the outer chain plate is a square structure. An arc-shaped welded stable cooperation groove is arranged at the position where the outer side of the outer chain plate structure cooperates with the pin.

[0006] Further, the cross-sectional dimensions of the transition smooth sleeve and the sleeve structure are exactly the same.

[0007] Further, the outer shapes and dimensions of the outer connecting plate and the inner chain plate structure are exactly the same.

[0008] Advantages of the present utility model:

[0009] By improving the structure of the existing plate chain, the present utility model provides a sleeve structure between the internal intermediate plates, ensuring better smoothness of the cooperation between the internal structure and the pin during use, and stronger wear resistance of the overall moving components during use. On its outer side, a double-layer outer chain plate structure is provided, and a welding cooperation groove is arranged between the outer chain plate and the pin, which can ensure higher overall strength at the connection position, stronger bearing capacity during use, and effectively improve the use safety, so as to meet the use requirements in application environments with relatively high strength requirements and be more reliable in overall safety during use.

[0013] As Figure 1 and Figure 2As shown in the figure, a high-strength improved plate chain includes an intermediate isolation support chain plate 1. Inner chain plate structures 2 are respectively arranged on both sides of the intermediate isolation support chain plate 1. An outer chain plate structure is arranged on the outer side of the inner chain plate structure 2. A sleeve structure 3 is arranged inside the inner chain plate structure 2. The inside of the sleeve structure 3 is combined with the outer chain plate structure through a pin shaft 4. The outer chain plate structure is composed of two superimposed outer connecting plates. The inner chain plate structure 2 is composed of three superimposed inner connecting plates. Based on the existing products, the structure is improved. The intermediate isolation support chain plate 1 is composed of two superimposed intermediate connecting plates, ensuring the structural strength at the intermediate position. A transition smooth sleeve 6 is arranged at the position where the inside of the intermediate isolation support chain plate 1 cooperates with the pin shaft 4, making the cooperation between the internal intermediate position structure and the pin shaft smoother, having better wear resistance during movement, and higher structural load-bearing strength. The cross-section of the outer side of the pin shaft 4 at the position where it cooperates with the outer chain plate is a square structure. An arc-shaped welding stable cooperation groove 5 is arranged at the position where the outer chain plate structure cooperates with the pin shaft 4, making the connection strength at the outer combination position reliable, having higher accuracy during welding cooperation, and being more convenient for welding operation. By improving the structure of the existing plate chain, by arranging a sleeve structure between the internal intermediate plates, it ensures that during the use of the whole, the cooperation between the internal structure and the pin shaft is smoother, and the wear resistance of the overall moving components during use is stronger. On its outer side, by arranging a double-layer outer chain plate structure and setting a welding cooperation groove between the outer layer chain plate and the pin shaft, it can ensure that the overall strength of the connection position is higher, having stronger bearing capacity during use, and effectively improving the use safety, so as to meet the use requirements in application environments with relatively high strength requirements and being more durable.

[0014] Preferably, the cross-sectional dimensions of the transition smooth sleeve 6 and the sleeve structure 3 are exactly the same, having lower cost during production and processing and being more convenient for maintenance during use.

[0015] Preferably, the outer connecting plate and the inner chain plate structure 2 have exactly the same external dimensions, making the flatness of the overall structure better during production and processing and having relatively lower production and processing costs.

[0016] The above is the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle described in the present invention, several improvements or replacements can be made, and these improvements or replacements should also be regarded as the protection scope of the present invention.
