[0011] Optionally, the limit plate and the nut gasket are both provided with a socket adapted to the fixing bolt.

[0012] By adopting the above technical solution, both the limiting plate and the nut gasket are provided with a socket matched with the fixing bolt, so that they can be sleeved on the fixing bolt for use.

[0013] Optionally, a fixing hole is opened in the middle of the nut limiting plate, and a fastening hole is opened in the middle of the bent plate.

[0014] By adopting the above technical solution, a fixing hole is opened in the middle of the nut limit plate, and a fastening hole is opened in the middle of the bent plate, which makes it easy to fix the nut to the sound barrier and avoid the nut loosening due to the frequent action and influence of high-speed rail pulses.

[0015] Optionally, anti-slip grooves are evenly arranged on the outer surface of the nut gasket.

[0016] By adopting the above technical solution, anti-skid grooves are evenly opened on the outer surface of the nut gasket, so that the nut gasket has a rough surface, and friction is used to prevent the nut from automatically loosening during use.

[0017] In summary, the present invention has at least one of the following beneficial effects:

[0018] The present application provides a limit plate to facilitate the tightening of the fixing bolts during use to avoid loosening during use. The provision of a nut gasket facilitates the limiting fixation of the nut. The provision of a nut limit plate and a bent plate facilitates the fixation of the nut to the sound barrier to avoid the frequent action and influence of high-speed rail pulses that cause the nut to loosen. The double-layer fixation of the nut effectively solves the problem of loosening of the nut at the bottom of the sound barrier column, thereby ensuring the safe operation of high-speed trains.
