Installation Conditions And Steps Of Plug-In Buffer Stoppers
There are many equipments on the railway, and the buffer stopper is one of them that cannot be ignored. There are many types of buffer stoppers. Among them, the plug-in buffer stopper is the focus of this article. The plug-in buffer stopper is a device to ensure the safety of railway traffic. Do you know its installation conditions and how it is installed?
In order for you to better understand the plug-in buffer stopper, but also to solve the above problems, let's take a look at the relevant knowledge points!
1. The technical conditions of the railway line should conform to the standards for public works.
2. The plug-in buffer stoppers should be installed on a section of the rail behind the end of the end line, close to the rail joint and where there is no fish plate, the stop should be at a certain distance from the end of the end line. The greater the distance, the better the braking effect .
3. The correct working installation method of the plug-in buffer stopper:
①Place the left and right arms on the base rail first, and connect it to the support with the arm pin.
② Raise the support arm and place the spring seat, leaf spring and bearing seat on the basic rail below the hoof-shaped fast.
③ Clamp the shoe block with the brake rail, 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 outer bolts must pass through the support frame, and the bearing should be located in the middle of the pressure hole.
④Connect the four legs at the lower side of the two arms with the front and rear beams and the upper and lower inclined beams. The overlapping form is shown in the figure. The middle and four corners of the two inclined beams are pinned. After completing the above initial installation, tighten the bolts.
⑤ The installation of the booster is to place the spring seat, the leaf spring and the bearing on the basic rail in sequence, then use the two booster brake rails to sandwich it in the middle, and also clamp the rail head of the basic rail, and then use two Bolts tighten the brake rail.
⑥Pressurize each spring plate with a pressurizer: Insert the U-shaped pressurization quickly into the neutral positions on both sides of the bearing, and the head of the pressurized screw rod installed on the center nut of the pressurizer is aligned with the pressurized block, hanging on the The pressure rail bottom plate is hooked on the basic rail bottom plate, tightened with nuts, and the pressure screw is screwed with an iron rod with a length of about 1.5 meters and the wedge iron is driven between the bearing seat and the plate spring, so that the gap between the plate spring and the spring seat is 0.6 0.05 mm.
⑦Install the plug-in buffer stop sign on the support.
⑧Each time the installation is completed, the position mark should be painted on the rail waist to facilitate daily inspection whether the plug-in buffer stopper is damaged.
You must be very clear about the installation conditions and specific installation steps of the plug-in buffer stopper. Of course, if you have more professional questions about the plug-in buffer stopper, please feel free to leave us an online message!
