[0019] It should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "set / equipped" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] like Figure 1 As shown, the impact protection device structure of the high-speed rail tuning equipment includes a base plate 1 and a cover 2 that is fastened to it. A buffer shell 3 is fitted on the outside of the cover 2. Multiple protruding reinforcing ribs 41 are provided on the outer surface of the cover 2 and the inner surface of the buffer shell 3. The reinforcing ribs 41 are provided with multiple through holes 42. Springs 43 pass through the through holes 42 in sequence to connect the cover 2 and the buffer shell 3; or the through holes of the cover 2 and the through holes of the buffer shell 3 are connected by a metal elastic folding plate.

[0021] Its working principle is as follows: The base plate 1 of the impact-resistant protective device is installed on the foundation on both sides of the high-speed rail track. The surface of the base plate 1 is fitted with a tuning device (such as ZPW2000) through a frame, and the cover 2 is fastened to the base plate 1 by means of socket engagement or bolt fixation. Since the cover 2 is fitted with a buffer shell 3, and springs 43, metal elastic folding plates and other components are set between the buffer shell 3 and the cover 2, the two achieve buffering and vibration reduction. When subjected to impact, the buffer shell 3 and the cover 2 have an elastic damping effect. In terms of specific structure, multiple reinforcing ribs 41 are set on the outer surface of the cover 2 and the inner surface of the buffer shell 3, and several through holes 42 are provided on the reinforcing ribs 41. The springs 43 or metal elastic folding plates pass through or are welded to the through holes 42 in sequence, realizing the integrated structure of the buffer shell 3 and the cover 2.

[0022] It should be noted that the reinforcing ribs 41 can be spirally wound or arranged side by side in parallel, and the reinforcing ribs 41 on both sides of the spring 43 or the metal elastic folded plate are preferably positionally corresponding to ensure that the spring 43 or the metal elastic folded plate is arranged in order between the two groups of through holes 42 and balanced in stress.

The rotating shaft 63 of the traction handle 62 and the sliding sheet 64 at the end enter the fan-shaped sliding groove 65 through the opening. At this time, rotating the traction handle 62 makes the sliding sheet 64 horizontally rotate and form a limit with the fan-shaped sliding groove 65, realizing clamping connection.
