[0002] In the subway operation system, the handrail is used as an important part of the ring composition to ensure the safety and comfort of passengers, its safety, durability and whether it meets the industry standards and regulations are directly related to the vital interests of the majority of passengers and the overall quality of subway operation. As the core force of urban public transportation, the subway carries a large number of passengers every day. During the train starting, braking, turning and running process, the ring composition will be frequently subjected to the force of passengers' grip, swing and other forces. These forces not only have changes in direction and size, but also have a very high frequency of action. Under such working conditions for a long time, various components of the ring composition, such as connecting pieces, ring bodies and connecting parts with handrail rods, may have safety hazards due to fatigue, wear and tear and other reasons.

[0003] Once the ring composition appears loose, broken and other failures, it is likely to cause passengers to lose balance and fall during the grip process, and even more serious safety accidents may occur, which poses a serious threat to the safety of passengers. At the same time, the damage of the ring composition will also affect the normal operation order of the subway train, increase the maintenance cost and downtime, and reduce the efficiency and service quality of the subway operation. Therefore, in order to ensure that the subway handrail ring composition can run stably and reliably in actual use, it is particularly important to conduct comprehensive and strict durability test on the processed ring composition.

The former method is time-consuming, labor-intensive and difficult to ensure the accuracy of the test, and the latter method is expensive. Therefore, it is necessary to design a swing durability test device for the subway handrail ring composition to effectively solve the above technical problems. UTILITY MODEL CONTENTS
