Description

Technical Field

[0001] This invention relates to the field of railway equipment connection technology, specifically a high-strength railway forged aluminum connection assembly. Background Technology

[0002] Railway forged aluminum connecting components are key connecting parts of railway equipment. They are mostly used for connecting railway track sections, car bodies and chassis support structures. With forged aluminum as the core material, they combine lightweight and load-bearing capacity. Their core function is to achieve a stable connection between components and load transfer, ensuring the stability of the railway operation structure.

[0003] Existing railway forged aluminum connecting assemblies mostly adopt a planar butt connection method. However, planar butt connections have a small contact area and weak shear resistance, making them prone to misalignment when exposed to vibration. Furthermore, they lack a dedicated positioning structure, making assembly inconvenient and requiring repeated positioning. Bolts rely on ordinary washers for anti-loosening, which are also prone to loosening under vibration, thus requiring frequent maintenance and potentially affecting the service life of the connecting assemblies, thus exhibiting certain limitations. Summary of the Invention

[0004] The purpose of this invention is to provide a high-strength railway forged aluminum connecting assembly to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-strength railway forged aluminum connecting assembly, including a fixing mechanism, wherein a set of connecting mechanisms are connected to both the left and right ends of the fixing mechanism; The fixing mechanism includes a central base, a fixing groove, a guide groove, a threaded hole, a covering groove, and a reinforcing groove. The central base has a set of fixing grooves at the middle of both the left and right sides. The upper and lower surfaces of the two sets of fixing grooves are provided with guide grooves. The upper and lower guide grooves are provided with threaded holes. The central base has a covering groove corresponding to the fixing groove at both the front and rear ends. The covering grooves at both the left and right ends are provided with reinforcing grooves at both the front and rear sides.

[0006] Preferably, the components of the connecting mechanism at both ends are the same. The connecting mechanism at the right end includes a connector, a groove, a connecting base, a limiting groove, a protruding plate, a through hole, and a cover panel. The connector has a groove at the middle left end. A set of connecting bases is provided in the middle of the groove. The left side of the connecting base extends out of the groove and is provided with no less than two sets of limiting grooves at equal intervals. The connecting base has protruding plates at both the top and bottom ends. The inner end of the connecting base is provided with through holes corresponding to threaded holes. A set of cover panels is hinged to both the front and rear ends of the groove.

[0007] Preferably, the inside of the through hole is provided with an adhesive through a covering film.

[0008] Preferably, the cover panel has an "L" shaped structure, which is opposite to the cover groove and the reinforcement groove.

[0009] Preferably, the top end of the upper threaded hole extends through the fixing groove to the top surface of the middle seat, and the bottom end of the lower threaded hole extends to the inner bottom end of the middle seat.

[0010] Preferably, the inner sides of both sets of fixing grooves are provided with flanges corresponding to limiting grooves.

[0011] Compared with the prior art, the beneficial effects of the present invention are: The connecting mechanisms, located at the left and right ends of the fixing mechanism, include components such as a central seat, fixing groove, guide groove, threaded hole, cover groove, and reinforcement groove. These components work together to facilitate the fixed connection of adjacent sets of connecting mechanisms, ensuring the stability and strength of the connection and thus adapting to the normal operation of the railway. The connecting mechanisms also include components such as connectors, grooves, connecting bases, limiting grooves, protruding plates, through holes, and cover panels.

Detailed Implementation

[0018] To further explain the technical solution of the present invention, a detailed description is provided below through specific embodiments.

[0019] Please see Figure 1-3This invention provides a high-strength railway forged aluminum connecting assembly, including a fixing mechanism 1. A set of connecting mechanisms 2 is connected to both the left and right ends of the fixing mechanism 1. The fixing mechanism 1 includes a central base 11, fixing grooves 12, guide grooves 13, threaded holes 14, covering grooves 15, and reinforcing grooves 16. A set of fixing grooves 12 is provided at the middle of both the left and right sides of the central base 11. Guide grooves 13 are provided on the upper and lower inner surfaces of both sets of fixing grooves 12 to facilitate the guidance of the connecting mechanisms 2 during insertion and improve connection accuracy. Threaded holes 14 are provided in the guide grooves 13 at both the upper and lower ends. The top end of the upper threaded hole 14 extends through the fixing groove 12 to the top surface of the central base 11 to facilitate the connection of external bolts. The bottom end of the lower threaded hole 14 extends to the inner bottom of the central base 11 to facilitate bolt fixing. Covering grooves 15 corresponding to the fixing grooves 12 are provided at both the front and rear ends of the central base 11. Reinforcing grooves 16 are provided on the front and rear sides of the covering grooves 15 at both the left and right ends to strengthen the connection and provide stable reinforcement.

[0020] Please see Figure 1-5 This invention provides a high-strength railway forged aluminum connecting assembly. The components of the connecting mechanisms 2 at both ends are identical. The right-end connecting mechanism 2 includes a connector 21, a groove 22, a connecting base 23, a limiting groove 24, a protruding plate 25, a through hole 26, and a cover panel 27. The connector 21 has a groove 22 at its left middle end, and a set of connecting bases 23 is provided in the middle of the groove 22. The connector 21 and the connecting base 23 are integrated, which can effectively improve the connection strength. The left side of the connecting base 23 extends outside the groove 22 and is provided with no less than two sets of limiting grooves 24 at equal intervals. The inner side of the fixing groove 12 is provided with a flange corresponding to the limiting groove 24. After the connecting base 23 is inserted into the fixing groove 12, the connection stability and connection accuracy are further enhanced by the cooperation of the flange and the limiting groove 24. The upper and lower ends of the connecting base 23 are provided with protruding plates 25 corresponding to the guide grooves 13, which is beneficial for guiding the connecting base 23 when it is inserted into the fixing groove 12. Each inner end of the connecting base 23 has a through hole 26 corresponding to the threaded hole 14. External bolts can pass through the through hole 26. The inner side of the through hole 26 is covered with an adhesive 262 through a covering film 261. When the external bolt passes through the through hole 26, the external thread breaks the covering film 261, causing the adhesive 262 covered by the covering film 261 to flow out and fill the space between the through hole 26 and the bolt, as well as between the fixing groove 12 and the connecting base 23, thereby improving the connection stability and preventing loosening. A set of covering panels 27 are hinged at both the front and rear ends of the groove 22. The covering panels 27 have an "L" shape structure and are opposite to the covering groove 15 and the reinforcing groove 16. When the covering panels 27 rotate, they can be inserted into the covering groove 15, and their longitudinal part can be inserted into the reinforcing groove 16. This can strengthen the connection stability and cover and protect the connection between the fixing mechanism 1 and the connecting mechanism 2, reduce the influence of external factors, and extend the service life.

[0021] The working principle is as follows: In use, the connecting base 23 is inserted into the fixing groove 12, and the protruding plate 25 moves along the guide groove 13 to guide the connecting base 23. After the connecting base 23 is inserted into the fixing groove 12, the connection accuracy between the connecting base 23 and the fixing groove 12 is further enhanced by the cooperation of the flange and the limiting groove 24. Then, the cover panel 27 is rotated to cover the cover grooves 15 at both ends, thereby protecting the connection part between the connecting base 23 and the fixing groove 12. Then, the bolt is rotated into the threaded hole 14. When the bolt passes through the through hole 26, it will break the cover film 261 and release the adhesive 262. The adhesive 262 is squeezed out of the upper and lower ends of the through hole 26 due to the pressure of the bolt, thereby filling and reinforcing the space between the through hole 26 and the bolt, as well as between the fixing groove 12 and the connecting base 23, to prevent loosening.
