XCD type fixed car stopper

XCD type fixed car stopper is a product designed to meet the specific requirements of the use unit in accordance with the actual situation of the use unit. The occupied line is short, the structure is simple, the cost is low, and the maintenance is convenient. It can be used in occasions where the vehicle group is small and the impact speed is not high.

xcd type fixed block

XCD type fixed car stopper is a safety device installed at the end of the railway to prevent the car from hitting the car stop when it slips away. ,支臂与制动轨采用的插接式连接方式,系国内首创, 安装简便,便于维修和复位The structure is reasonable, the braking force is large , and the plug-in connection method of the support arm and the braking rail is the first in China. The installation is simple and easy to repair and reset . 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.
,用在其他型车辆的挡车器在基本型号后面加辅助标记。 The basic model is: XCD type fixed car stopper, which is suitable for standard rail vehicles . The car stopper used in other types of vehicles is marked with an auxiliary mark at the back of the basic model.

XCD type fixed stopper-structure and working principle

/ STRUCTURE AND WORKING PRINCIPLE

Cushion rubber sheet

The impact force of the vehicle is composed of a cushion rubber sheet,
The left and right arms of the support are transmitted to the brake rail

Brake rail, spring seat. Friction resistance with basic rail prevents vehicle from sliding

It is composed of a plate spring, a spring seat, a wedge iron, and a bearing seat. It is installed in the brake rail of the main body frame. Its role is to form a pre-pressure when the stopper is static and increase the frictional resistance during braking. And in dynamic state, it can make the braking force work continuously until it stops.

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 vehicle stopper and the two rear pair of brake rails in sequence slide, and the frictional resistance gradually increases, which can prevent the vehicle and the main body from being damaged and increase the cumulative resistance of the vehicle stopper. Has a large braking capacity.

XCD type fixed stopper-installation method and required principle

/ METHOD AND PRINCIPLE

Fixed car stoppers-installation requirements

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.

XCD type fixed stopper-installation method

① Put the left and right arms on the basic rail, and connect them to the base with the arm 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 beams and the upper and lower oblique 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 oblique beams are attached with pin straps. After the initial installation is completed, tighten the bolts.
⑤ Press each spring plate with a presser: Insert U-shaped pressurized quick inserts into the neutral positions on both sides of the seat, and the head of the pressurized screw installed on the central nut of the presser is aligned with the pressurized block, and the 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.
⑥ Install the sign on the support.
完毕 After each installation, position marks should be painted on the rail waist to facilitate daily inspection of the car stopper for damage.

XCD type fixed stopper-repair

/ METHOD AND PRINCIPLE

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.
