Technical Field

[0001] The invention relates to the field of mechanical technology, and in particular to an anti-collision device for a follower bogie assembly. Background Art

[0002] Rail transit plays a very important role in my country's long-distance and large-volume transportation. Especially with the construction of high-speed railways, it has greatly facilitated people's travel. Taking high-speed railways has become the preferred way for people to travel. With the increase in the number of cars, cities are becoming more and more congested, especially during rush hours. In order to ease traffic pressure, more and more cities are starting to build subways, and subway travel accounts for an increasing proportion of people's daily travel. As an important part of rail vehicles, the bogie assembly is generally stored on the track. Storing it on the track facilitates the transportation and movement of the bogie assembly. When the bogie assembly moves on the track, it is inevitable that two bogie assemblies will collide with each other. The collision of the two bogie assemblies will cause the wheels to collide. Severe collisions will cause the wheels to be reworked or scrapped, and will also cause damage to other parts of the bogie assembly. Chinese patent publication number CN104843317A discloses a bogie anti-collision tooling and a bogie conveying method. Since the bogie anti-collision tooling applied for in the patent cannot be installed on the bogie assembly, in actual application, due to the heavy weight of the bogie, the anti-collision tooling will be derailed due to inertia, making the bogie anti-collision tooling lose its protective function. In view of this, how to design a technology to improve the reliability of use is the technical problem to be solved by the present invention. Summary of the invention
