Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of rail transit equipment, concretely relates to a sliding lifting type crescent car stop. BACKGROUND

[0002] Currently, in many domestic rail transit lines, the safety and compatibility of terminal protection equipment have become an important part of ensuring train operation safety. Traditionally, many lines use fixed crescent derailers as the last line of defense. However, this type of derailed has some inherent limitations in design, with relatively small braking capacity, often difficult to effectively stop the train in an emergency, thus unable to fully guarantee the safety of train operation. Especially when facing high-speed trains or heavy metro trains, the braking effect of this type of derailed is even more inadequate, and it is difficult to meet the expected safety protection standards. In addition to the problem of insufficient braking capacity, fixed crescent derailers also have compatibility problems with train equipment in terms of physical size. Because the height of these derailers is often higher than the height of the train and vehicle obstacle remover, when the train reaches the end of the line, the obstacle remover is likely to collide with the derailed, which not only causes damage to the train itself, but also may cause more serious safety accidents. In addition, with the continuous progress of modern train design, the bottom structure of some subway vehicles has become more complex, and various suspensions such as sensors, detection equipment, etc. are often installed in front of the wheels, which makes the train unable to pass through the high crescent derailed, further limiting the application range of this traditional protection equipment. More seriously, when the train slips due to various reasons (such as brake system failure, human error, etc.), if the protection equipment at the end of the line cannot effectively function, the train may collide with the crescent derailed at a high speed, causing serious damage to the derailed and the train itself. Even more terrible, this collision may trigger a chain reaction, such as track deformation, signal system damage, etc., thus posing a great threat to the operation safety of the entire line. Therefore, it is urgent to improve or replace the existing fixed crescent derailed. On the one hand, new types of derailers with stronger braking capacity need to be developed to better adapt to the high-speed and heavy-load characteristics of modern trains; on the other hand, more intelligent elements such as automatic detection and warning systems need to be integrated into the design of the derailed to improve its ability to respond to emergencies. At the same time, the height design of the derailed also needs to be more flexible to ensure good compatibility with various types of trains and avoid safety problems caused by size mismatch. Fixed crescent derailers have been difficult to meet the growing safety needs in the current rail transportation field. In order to ensure the absolute safety of train operation, it is necessary to speed up the pace of updating traditional protection equipment and introduce more advanced and reliable protection technology to protect China's rail transportation industry. This is not only a responsibility to the safety of passengers' lives and property, but also a strong support for the sustainable and healthy development of China's transportation industry.

The utility model has the advantages of simple structure, large braking capacity, safety and reliability, light weight, small size, convenient installation, no influence on personnel passing, and relatively significant economic benefits. On the basis of fully considering safety, the crescent car stopper can be widely applied to dead-end lines of various types of railway tracks, reduces the production cost of the railway, and is easy to maintain and repair.

[0004] However, the existing crescent car stopper has the problem of poor braking safety during use because the crescent car stopper relies on the friction between the damper and the rail to stop the car, and the traditional car stopper is fixed by bolts, which has a small fixed area, resulting in a sliding distance process and causing the problem of poor braking safety of the car stopper.
