Embodiment 1

[0054] Such as figure 1 , figure 2 , image 3 The floating track bed of the present invention shown includes a floating plate 1, an elastic vibration isolator 2 and a gasket 3. The elastic vibration isolator 2 used in this example is a spiral steel spring vibration isolator with a silicone oil liquid damping material inside. . The elastic vibration isolator 2 and the spacer 3 are arranged in the reserved through hole 5 of the floating plate 1, and the connecting sleeve 6 is integrated with the floating plate in the reserved through hole 5, and the connecting sleeve 6 is only provided with a support Block 7, a through hole is left in the center of the support block 7, the elastic vibration isolator 2 and the spacer 3 are compatible with the size of the central through hole of the support block 7, and the spacer 3 and the support block 7 can realize misalignment The gasket 3 is partly supported on the support block, and the floating plate 1 is supported on the elastic vibrat...

Embodiment 2

[0062] Such as Figure 7 , Figure 8The difference between the floating ballast bed of the present invention and the first embodiment is that since there is no need to set a jacking block, the connecting sleeve is canceled and instead it is integrated with the floating plate 1 on the inner wall of the reserved through hole 5 The protrusion 17 of the concrete structure, the protrusion 17 forms a shoulder W, and the gasket 3 is partly supported on the shoulder W. A square opening is arranged in the center of the protrusion 17, and the corresponding gasket 3 is arranged in a square shape. The central opening of the shoulder is compatible with the size of the elastic vibration isolator 2 and the spacer 3 , and the shoulder W and the spacer 3 can form a dislocation overlap. The floating plate 1 is supported on the elastic vibration isolator 2 through the spacer 3 and maintains an elastic floating state with the foundation 10 . The elastic vibration isolator 2 used in this exampl...

Embodiment 3

[0069] Such as Figure 11 , Figure 12 , Figure 13 The difference between the floating track bed of the present invention and the first embodiment is that a circular gasket 3 with a flange 19 is used. In order to save materials and reduce costs, a through hole is still provided in the center of the gasket 3 . In addition, in order to obtain the shoulder structure, the reserved through hole 5 is set as a stepped through hole, and the shoulder W is formed at the junction of the upper and lower holes, wherein the upper hole of the reserved through hole 5 cooperates with the gasket 3 to have a corresponding gap The diameter of the upper hole at the shoulder W is smaller than that of the lower hole. The gasket 3 is partly supported on the shoulder W, and the floating plate 1 is supported on the elastic vibration isolator 2 through the gasket 3 . The central opening of the shoulder W should be compatible with the size of the elastic vibration isolator 2 and the spacer 3, and the ...

Abstract

The invention relates to the field of track traffic, in particular to a track bed and a jacking device used when the track bed is jacked. The floating track bed comprises a floating plate, a gasket and an elastic vibration isolator, wherein a pre-reserved through hole or a side groove for accommodating the elastic vibration isolator and the gasket is arranged on the floating plate, and the floating plate is supported on the elastic vibration isolator through the gasket; an articulating hole for jacking is arranged on the floating plate and is of a ladder hole, and the interface of the upper hole and the lower hole of the ladder hole forms a retaining shoulder; and the size of the upper aperture is smaller than the size of the lower aperture. The floating track bed has simpler structure, requires lower requirements for the thickness of the floating plate and the jacking space, and stronger practicality, is more favorable for reducing cost when not affecting the vibration isolating efficiency, prolongs service life, and has more higher performance-price ratio and very broad market application prospects.

Description

technical field [0001] The invention relates to the field of rail transportation, in particular to a track bed and a jacking device used for jacking up the track bed. Background technique [0002] With social development and scientific and technological progress, large and medium-sized cities pay more and more attention to the development of urban rail transit, and urban rail construction, especially underground railway construction, has also been launched one after another. In order to reduce the disturbance to the upper part of the track or the surrounding properties and residents, it is an important vibration isolation measure in the design of the subway to set up a floating slab track bed in a special section. In order to save space and facilitate maintenance and replacement, most of the vibration isolation devices in the existing floating slab track bed system adopt a built-in structure. For example, the Chinese patent application No. 200710013713.1 published on August...
