Problems solved by technology

In the actual application process, on the one hand, due to the limitation of many factors such as space, cost and environment, the height reserved for the floating plate in many cases cannot accommodate a larger connecting sleeve, so the floating plate cannot be used; on the other hand , the height of the floating plate is often determined very late in the engineering design. Due to the change of the thickness of the floating plate, the size of the connecting sleeves of various heights is different, and stock production cannot be realized, so the delivery time is long
Especially when design changes are encountered during construction, because the corresponding period is long, it is easy to affect the construction progress

Embodiment 1

[0035] As shown in Figure 1, the split type vibration isolation device of the present invention includes a lower sleeve 1, an upper sleeve 2, a spring vibration isolator 3 and a gasket 4, wherein, the upper part of the lower sleeve 1 is provided with a support block 5, which is The simplified structure integrates the supporting block 5 and the connecting flange 6 at the top of the lower sleeve, and the upper part of the upper sleeve 2 is provided with a jacking block 7 . The lower sleeve 1 and the upper sleeve 2 are coupled together by means of the bolts 10 arranged between the connecting flange 6 at the top end of the lower sleeve 1 and the connecting flange 8 at the bottom end of the upper sleeve 2 . The thickness of the lower sleeve 1 is adapted to the thickness of the floating plate 9 .

[0036]The spring vibration isolator 3 includes a spring housing and a spring 21. The spring 21 is located in the spring housing 23 and is a helical spring with suitable rigidity in the ve...

Embodiment 2

[0042] As shown in Figure 1, Figure 5 and Figure 6, the difference from Embodiment 1 is that the upper sleeve 2 and the lower sleeve 1 are fixedly connected and preset in the floating plate 9. A dustproof cover 14 and a sealing gasket 15 are arranged above the sleeve 2 . Of course, the dustproof cover 14 can also be completely embedded in the upper sleeve 2, which is more attractive in appearance.

[0043] When in use, the lower sleeve 1 can be standardized and produced in stock, and the upper sleeve 2 can be processed according to the actual thickness of the floating plate 9 before delivery, and the height of the connecting sleeve can be quickly matched in the factory or on the construction site, so that there is It is beneficial to further shorten the processing cycle, improve construction efficiency, and can better meet the vibration isolation requirements of floating slabs with different thicknesses or floating slabs with continuously changing thicknesses. In addition to ...

Embodiment 3

[0045] As shown in Figure 7, the difference from Embodiment 1 is that the connecting flange at the bottom of the upper sleeve 2 is canceled, and the pin holes provided on the side walls of the lower sleeve 1 and the upper sleeve 2 are used to connect the two through pins 16 together.

[0046] The structure of the upper sleeve 2 adopting this connection method is simpler, less material is used, and the cost is correspondingly lower. The space above the supporting block 5 of the lower sleeve 1 can be used to place a dust cover (not shown in the figure) after the upper sleeve 2 is removed, and the space utilization is more compact and more reasonable. Of course, threaded holes can also be provided, and bolts can be used instead of pins to realize the connection.

[0047] In addition to the cooperating connection between the pin holes and the pin bolts, it is also possible to set the pin bolts on the side walls of the upper and lower sleeves, and the upper and lower sleeves are c...

Abstract

The invention belongs to the vibration and noise control field, especially relating to a vibration isolating device for rail vehicle, comprising: connecting sleeve and spring vibration isolator, where the connecting sleeve is equipped with support stop and lift stop and comprises upper and lower sleeves, a splitting connecting structure is arranged between the upper and lower sleeves, the support stop is arranged at the upper part of the lower sleeve and the lift stop is arranged at the lower part of the upper sleeve. And the invention has features of compact and reasonable structure, low cost, enlarging the application range of under-roadbed vibration isolating devices, strong practicality, and having both economic and environmental protection effects, able to be applied to thinner rail floating slabs.

Description

technical field [0001] The invention belongs to the field of vibration and noise control, and in particular relates to a vibration isolation device for alleviating the adverse effects caused by the vibration and noise emitted during the operation of rail vehicles or reducing the vibration of building components and equipment foundations. Background technique [0002] The traditional rail transit structure will generate large vibration and noise when the vehicle is running. These vibration and noise not only affect the nearby buildings and equipment, but may also cause harm to the human body. Therefore, for urban areas with relatively concentrated population and buildings, the problem of vibration and noise reduction of rail transit is particularly important. Existing vibration reduction measures are divided into three levels: under-rail vibration isolation, under-pillar vibration isolation, and under-ballast bed vibration isolation according to the different nodes involved i...
