Description

Technical Field

[0001] This utility model relates to the field of vehicle air cylinder hoisting technology, and in particular to an air cylinder clamping belt used for hoisting air cylinders in urban rail vehicles. Background Technology

[0002] In the operating system of urban rail vehicles, the air cylinder, as a key component for storing compressed air, provides a stable air source for multiple systems such as braking and door control. The stability and reliability of its installation directly affect the operational safety and performance of the vehicle. With the rapid development of urban rail transit, more stringent requirements have been placed on the safety and adaptability of the air cylinder hoisting system.

[0003] Air cylinder hoisting typically employs a clamp-type structure. Installation requires aligning the connecting lugs (or studs) at both ends of the clamp with the mounting holes on the vehicle body, and then tightening them with fasteners. However, due to manufacturing errors in urban rail vehicles, the actual position of the mounting holes often deviates from the design benchmark. This necessitates repeatedly prying the clamp or fine-tuning the mounting base position to achieve hole alignment during installation. This process not only consumes a significant amount of manpower, but forced alignment can also generate additional stress on the clamp, increasing the risk of breakage due to stress concentration after long-term use. Furthermore, it makes it difficult to guarantee the accuracy of the connection, affecting the overall stability of the air cylinder hoisting.

[0004] Clamp-type chucks typically require welding the chuck body to the fixing lugs (or studs), and quality control during the welding process is crucial. Welding deformation, defects, and improper heat control can lead to changes in material properties, such as decreased hardness and toughness, thus affecting the chuck's strength. Therefore, a chuck for hoisting air cylinders in urban rail vehicles is needed to address these issues. Utility Model Content
