Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle traction, and in particular relates to a traction coupling device for rail transportation. Background Art

[0002] Broadly speaking, rail transit vehicles are a type of transportation that travels along specific routes. In my country, they can be divided into passenger and freight types. Because they generally lack a power unit, they must be connected together and driven by a locomotive to travel along the route.

[0003] The traction coupling devices currently used in rail transit vehicles have several drawbacks. If a jam occurs, vehicle maintenance becomes complicated and costly. Furthermore, railway personnel must manually and precisely align the coupling device to achieve coupling, which undoubtedly increases their workload and can lead to overwork and exhaustion. Furthermore, prolonged manual coupling operations without adequate protective measures can easily injure railway personnel's hands, posing a threat to their safety and health while performing coupling tasks. Utility Model Content

[0004] In view of the above problems existing in the existing devices, the present invention discloses a traction coupling device for rail transit, comprising:

[0005] The traction beam has a second connecting hole on its rear side. A plug-in rod is assembled to the front of the connecting rod through the fixing hole and the second connecting hole. A connecting column is provided on the rear side of the connecting rod, bolted to both sides of the rear side of the connecting rod. A traction hole is provided on the front side of the traction beam. A cylindrical crossbeam is welded inside the traction hole. Traction grooves are provided on either side of the traction hole. A small cylindrical crossbeam, number two, is welded inside the traction grooves. A traction link is mounted on the cylindrical crossbeam. A fixed disc is provided at the front of the traction link, and a square hole is provided inside the traction link.

[0006] The long crossbeam passes through the square hole inside the traction link. The round holes of the fixed rod are respectively fixed on the small cylindrical crossbeam No. 2 in the traction groove and the small cylindrical crossbeam No. 1 in the long crossbeam. The traction rod is matched with the fixed disc at the front of the traction link and is externally connected to the outside of the flat head pin. It can rotate relative to the traction link or separate from the traction link.

[0007] The connecting assembly includes a connecting beam, connecting hole No. 1, a flat head pin, a positioning groove, a fixing groove, and a cotter pin. The connecting beam is connected to the front side of the traction rod, and the rear side of the connecting beam is provided with connecting hole No. 1. The upper and lower sides of connecting hole No. 1 are provided with positioning grooves and fixing grooves. The flat head pin passes through the interior of the connecting beam through the positioning groove, connecting hole No. 1 and the fixing groove, and the cotter pin is assembled at the tail of the flat head pin.

[0008] In the improved solution, in order to reduce the need for railway personnel to manually align the coupling, as a preferred rail transit traction coupling device of the utility model, in order to effectively connect the traction link and the traction rod, and thereby assist the smooth operation of the traction link, in a preferred rail transit traction coupling device design of the utility model, traction grooves are carefully designed on both sides of the front side of the traction beam, and these traction grooves are cleverly equipped with fixing rods.

[0009] In the improved solution, in order to further enhance the stability of the coupling device, a long crossbeam is cleverly connected through the front end of the fixed rod. This design aims to firmly fix the traction link and ensure the stability of the connection.

[0010] In the improved solution, to facilitate the installation and removal of the connecting rod, the utility model innovatively installs a flat pin on the right side of the connecting beam. This flat pin not only penetrates the connecting beam to its inner side, but also cleverly achieves a seamless interlocking connection between the traction link and the traction rod, greatly simplifying the installation process.

[0011] Compared to existing technologies, the rail transit traction coupling device of this utility model exhibits significant technical advantages. It allows railway personnel to easily pull the traction rod into position using only the traction link, eliminating the need for manual alignment of the connection device as previously required. This undoubtedly reduces labor costs and greatly improves work efficiency. Furthermore, the traction link's secure fixation of the traction rod makes the entire coupling process simpler and faster, significantly reducing the workload of railway personnel and effectively preventing potential hand injuries. In short, the seamless coordination of the traction link and traction rod not only enhances the convenience of the coupling device but also marks another advancement in rail transit technology.
