The train running wheel 120 acts on the running surface of the U-shaped floating plate 110. The train guide wheel 130 acts on the guide surface of the U-shaped floating plate 110. The running surface protrudes inward. When tilted, it can interact with the guide wheel 130 to ensure the safety of driving. A U-shaped base 140 is arranged at the bottom of the U-shaped floating plate 110. The U-shaped base 140 adopts a reinforced concrete structure.

Three elliptical baffles 153 are provided on the inner wall of the metal sleeve 151, and the centers of the three elliptical baffles 153 are welded at equal angles at the upper part of the center of the cross section of the metal sleeve 151, so as to bear the interaction force between the steel spring isolators 152, and a trapezoidal reinforcement baffle 154 is provided between the three elliptical baffles 153, and the trapezoidal reinforcement baffle 154 is provided in the middle of the plane of the three elliptical baffles 153, and the right-angle waist One side is welded to the inner wall of the metal sleeve 151, and the lower bottom of the trapezoidal reinforcement baffle 154 is welded to the middle position of the three elliptical baffles 153, which is used to reinforce and share the force at the welding point of the three elliptical baffles 153. A circular cover plate 155 is arranged on the top of the metal sleeve 151, and the upper bottom of the trapezoidal reinforcement baffle 154 is used to support and fix the circular cover plate 155. A sealing ring is arranged on the outer side of the circular cover plate 155 to improve the sealing performance. The U-shaped floating plate 110 is elastically supported on the steel spring isolator 152 through the three elliptical baffles 153, and the steel spring isolator 152 transmits the force to the U-shaped base 140, forming a vibration reduction structure of the inner guided rubber wheel system.

[0035] Furthermore, the steel spring isolator 152 includes a coil spring 1521, an upper force baffle 1522, a lower force baffle 1523, an outer sleeve 1524, an adjustment bolt 1525 and an anti-slip pad 1526. The coil spring 1521 is installed inside the outer sleeve 1524, the adjustment bolt 1525 is arranged in the middle of the steel spring isolator 152, the upper force baffle 1522 and the lower force baffle 1523 are installed at the upper and lower ends of the outer sleeve 1524, and a circular groove is arranged in the middle of the upper force baffle 1522 and the lower force baffle 1523. The circular groove is used to limit and fix the coil spring 1521, and the upper force baffle 1522 and the lower force baffle 1523 are The metal component, the shape of the upper force baffle 1522 and the lower force baffle 1523 is consistent with the size of the gap formed by the three elliptical baffles 153 in the metal sleeve 151, so that the upper force baffle 1522 and the lower force baffle 1523 can pass through the gap of the three elliptical baffles 153, and a circular hole is left between the upper force baffle 1522 and the lower force baffle 1523 for the passage of the height adjustment bolt 1525; the outer sleeve 1524 adopts a damping shell, which is connected to the upper force baffle 1522 and the lower force baffle 1523 as a whole through a sealant, and the coil spring 1521 is fixed to the outer sleeve through the circular grooves of the upper force baffle 1522 and the lower force baffle 1523. In the cylinder 1524, the bottom surface of the lower force baffle 1523 is connected with a high coefficient anti-skid pad 1526 to prevent the steel spring isolator 152 from horizontal displacement. The height adjustment bolt 1525 forms an interaction force with the external thread channel 170 through the circular holes of the upper force baffle 1522 and the lower force baffle 1523, so as to be used for height adjustment and leveling of the U-shaped floating plate 110. In actual operation, the static and dynamic loads borne by the train running surface are transmitted to the coil spring 1521 through the three elliptical baffles 153 and the upper force baffle 1522, and finally to the U-shaped base 140. Since the coil spring 1521 has good elasticity in all directions, the transverse direction of the coil spring 1521 is The ratio of axial stiffness to vertical stiffness can be arbitrarily designed according to requirements, so the U-shaped floating plate 110 has good stability in all directions and does not require lateral support; the U-shaped floating plate 110 also uses the groove gutter 162 as a lifting channel, and at the same time, the height and level are adjusted steplessly by adjusting the bolts 1525, so that the structure is simple; the two sides of the U-shaped base 140 are at the same height as the running surface, ensuring that after the steel spring isolator 152 is damaged, the U-shaped floating plate 110 is separated from the predetermined position, thereby increasing the safety of the structure; the outer sleeve 1524 can absorb the structural vibration energy and rigid body vibration energy of the U-shaped floating plate 110, thereby increasing the overall stability of the system structure and increasing the shock absorption and noise reduction capabilities of the structure.

[0036] Furthermore, the steps for replacing the steel spring isolator 152 are as follows: first, from the square channel 161, a lifting device is used to act on the groove drain ditch 162 to lift the U-shaped floating plate 110, and after loosening the height adjustment bolt 1525, when the steel spring isolator 152 is rotated to be compatible with the openings of the three elliptical baffles 153, the damaged steel spring isolator 152 is taken out, and the new steel spring isolator 152 is inserted from the openings of the three elliptical baffles 153 of the metal sleeve 151 to be compatible under the three elliptical baffles 153, and then the height adjustment bolt 1525 is aligned with the threaded channel 170, and the height adjustment bolt 1525 is pre-tightened, and then the steel spring isolator 152 is rotated about 60°, so that the upper force baffle 1522 and the three elliptical baffles 153 are staggered and overlapped, and after the steel spring isolators 152 on both sides of the same cross-section are placed, the U-shaped floating plate 110 is heightened and leveled by the height adjustment bolts 1525 on both sides.

[0037] The working principle of the utility model is as follows:

[0038] When using a vibration reduction and noise reduction structure based on an inner-guided rubber wheel system in this embodiment, a U-shaped base 140 is first cast, and the built-in threaded channel 170 is pre-buried in advance according to the density of the coil spring 1521. After the maintenance is completed, the steel spring isolator 152 is placed and the height adjustment bolt 1525 is pre-tightened. Then, the metal sleeve 151 is placed on the steel spring isolator 152, and the three elliptical baffles 153 are staggered and overlapped with the upper force baffle 1522. After the force is formed, the U-shaped floating plate 110 is cast and maintained. After the maintenance is completed, the U-shaped floating plate 110 is heightened and leveled by the height adjustment bolts 1525 to strictly control the construction accuracy.
