Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of rail transit equipment, and specifically relates to a car stopper with safety protection function. BACKGROUND

[0002] When a train is speeding along the railway track and is about to reach the station where it needs to stop, a complex and critical safety issue emerges: due to the huge mass of the train and the resulting inertia, even if emergency braking is applied, it is difficult for the train to slow down rapidly and come to a smooth stop within the specified braking distance. This phenomenon is more pronounced on heavy freight trains or high-speed passenger trains, posing a serious challenge to the safety and efficiency of railway transportation. To effectively address this problem and ensure that the train can stop quickly and safely when necessary, engineers have designed and installed various advanced car stopper systems, providing a strong guarantee for the safety of train braking. As an auxiliary braking device specially designed for railway safety, the working principle of the car stopper is based on the principle of energy absorption and conversion in physics. They are usually installed at the end of the railway line, the entrance of the station, the maintenance section or any area where forced deceleration and stopping are required. Depending on the application scenario, there are various types of car stoppers, including but not limited to buffer car stoppers, hydraulic buffer car stoppers, and more advanced electromagnetic braking car stoppers. These devices help trains significantly reduce speed in a short time by absorbing train kinetic energy, dispersing impact force, or using friction, ultimately achieving safe stopping. Buffer car stoppers, as the most basic type, are usually composed of a series of elastic materials (such as rubber, springs) and rigid structures. When a train collides, these materials can effectively absorb collision energy and reduce the impact force on the train and the track. Hydraulic buffer car stoppers go one step further, using the incompressibility and damping effect of liquids to convert the kinetic energy of the train into heat energy, achieving a more stable deceleration process. This type of car stopper not only improves braking efficiency but also significantly extends the service life of the equipment. In recent years, with the advancement of technology, electromagnetic braking car stoppers have begun to emerge. This type of car stopper uses the power of electromagnetic fields to activate quickly when a train approaches, applying additional braking force to the train through electromagnetic attraction or repulsion, working in conjunction with the mechanical braking system to significantly shorten the braking distance. The advantage of electromagnetic braking car stoppers is their fast response speed, high control accuracy, and ability to automatically adjust braking force according to the speed and weight of the train, achieving more intelligent braking management. In addition to technological innovation, the effective use of car stoppers also depends on strict maintenance management and regular inspection. Railway departments will regularly test the performance of car stoppers to ensure they are in good working condition. At the same time, scientific and reasonable braking strategies are developed for different types of trains and operating conditions to ensure that the car stopper can be quickly activated in emergency situations, ensuring the safety of passengers and cargo.

[0003] According to the patent number: CN221162764U, a mine electric car stopper is disclosed, which comprises two bases, the upper surfaces of the two bases are fixed with support rods, the opposite sides of the two support rods are fixed with a top plate, the upper surface of the top plate is provided with a lifting device, the lower surface of the lifting device is provided with an intercepting rod, the left and right sides of the intercepting rod are fixed with sliding cylinders slidingly connected to the outer sides of the support rods, the front of the intercepting rod is provided with an intercepting mechanism for enhancing the intercepting strength, and the bottom walls of the inner cavities of the two bases are provided with limiting mechanisms for limiting the height of the intercepting rod. The mine electric car stopper can increase the impact area of the mine car under the action of the intercepting mechanism, so that the impact force generated when the mine car collides is dispersed, thereby reducing the impact strength, so that the car stopper can withstand more severe impact, and the intercepting plate will not overturn backward after being impacted, causing the interception to fail.

[0004] However, the existing car stopper needs to be fixed on the rail during use, and the impact of the car and the train when stopping is large, which causes fatigue damage of the connection between the rail and the car stopper after repeated impact.
