The structure is reasonable, the braking force is large, and the plug-in connection method of the support arm and the braking rail is simple to install and easy to repair and reset.
The basic model is: CDH-C-plug-in sliding car stopper, which is suitable for standard railroad vehicles. The height of the center of the buffer seat from the rail surface is 850mm.
The geometry of the buffer seat and the height of the center distance from the track surface of the vehicle stopper match the geometry of the braked vehicle coupler and the height of the center distance of the track surface. The width of the main body frame corresponds to the gauge of the track, forming a series of products. But it is used for various vehicles of standard rail, wide rail, narrow rail and urban rail transit.
The meaning is as follows:
|Wide rail||Narrow gauge||Light Rail||subway||City fast|
|12th place||Impact speed km / h (divided into 10, 15, 20, 25, 28, etc.)|
|456th||Height of bearing center to rail surface mm|
Cushion rubber sheet
The impact force of the vehicle is transmitted to the brake rail by the buffer rubber plate and the left and right arms of the support.
Brake rail, spring seat. Friction resistance with basic rail prevents vehicle from sliding
It is composed of leaf spring, spring seat, wedge iron, and bearing seat. It is installed in the brake rail and booster brake rail of the main frame. Its role is to form a pre-pressure when the stopper is static and increase Friction resistance during braking, and can make the braking force continue to work in dynamic, until stopping.
The arm plate is made of a whole plate, and the main frame is composed of the support, the front and rear beams, and the upper and lower inclined beams. The structure is reasonable, the whole is strong, and it can withstand the impact of the vehicle at a higher speed.
The arm plate is directly inserted into the brake rail by the lower hoof block. The structure is simple, and the installation, maintenance and reset are convenient.
After the main frame is stressed, the two pairs of brake rails in front of the stopper, the two rear pairs of brake rails, and the two pairs of boosters will slide in order, and the frictional resistance gradually increases, which can prevent the vehicle and the main frame from being damaged, and can also block the vehicle Device cumulative resistance increases. Has a large braking capacity.
|Structural strength allows maximum impact speed v and energy height h|
|3rd gear||CDH-C20||v = 20 km / h||h = 1.57m|
|4th gear||CDH-C25||v = 25 km / h||h = 2.46m|
|Total horizontal resistance when sliding|

The technical conditions of the line should meet the engineering standards, and the gauge is 1435 + 6-2;
The stopper should be installed at the last section of the rail at the end of the line, close to the rail joint and without fishtail. The stopper should be at a certain distance from the end of the end of the line. The greater the distance, the better the braking effect.
① Put the left and right support arms on the basic rail, and connect them to the support with the support pin.
② Raise the support arm, and place the spring seat, leaf spring and bearing seat in this order on the basic rail under the hoof.
③ Use the brake rail to clamp the shoe block, and also clamp the rail head of the basic rail, and then use three bolts to bring the brake rail on. Note that the two bolts on the outside must pass through the support frame, and the seat should be in the middle of the pressure hole.
④ Use the front and rear crossbeams and the upper and lower inclined beams to connect the four feet under the two arms. The overlapping form is shown in the figure. The middle and four corners of the two inclined beams are pinned. After the initial installation is completed, tighten the bolts.
⑤ The installation of the booster is to place the spring seat, the leaf spring and the bearing in order on the basic rail, and then sandwich it with the two booster brake rails, and also clamp the rail head of the basic rail, and then use two Bolts to tighten the brake rail. The first pair of boosters is 100 mm from the main body frame, and the second pair of boosters is 80 mm from the first pair, parallel to each other, and the error is not more than 2 mm.
⑥ Press each spring plate with a presser: insert the U-shaped pressurized quick insert into the neutral position on both sides of the seat, the head of the pressurizing screw installed on the central nut of the presser is aligned with the pressurizing block, The bottom plate of the pressure rail is hooked on the bottom plate of the basic rail. Tighten it with a nut. Turn the pressure screw with an iron rod about 1.5 meters long and drive the wedge iron between the bearing and the plate spring. The gap between the plate spring and the spring seat is 0.6 ± 0.05 mm.
⑦Install the sign on the support.
⑧ After each installation, position marks should be painted on the rail waist to facilitate daily inspection of the car stopper for damage.
The car stopper should be restored to its original position in time after being hit. You can take out the wedge iron, push the main body frame and booster back to the original position, and then re-tighten and pressurize according to the above method.
Keep the car stopper in a good working condition and check it sequentially every month to confirm if there is any displacement, deformation and loose screws, and immediately deal with it if there is something abnormal.
Attention should be paid to clear the obstacles on the rail surface in the direction of sliding of the vehicle stopper, and handle the super-high road studs and sleeper bolts.
Apply anti-rust paint to the car stopper every two years.
