Embodiment 1

[0031] Such as Figure 1 to Figure 4 As shown, this embodiment provides a track isolation device for important cabinets, including a lower frame steel plate 6 at the bottom and a dustproof plate 12 for the cabinet at the top, and a lower simple harmonic track 2 is arranged horizontally on the lower frame steel plate 6, The lower frame steel plate 6 is provided with a lower beam 4 that can reciprocate along the lower harmonic track 2 in the lower harmonic track 2, and two sets of lower pulley assemblies 5 are respectively arranged on both sides of the lower beam 4 in the lower harmonic track 2 , the lower frame steel plate 6 is provided with the lower guide tensile assembly 3 for preventing the lower pulley assembly 5 from slipping out of the lower harmonic track 2, and the upper section of the lower beam 4 is provided with two upper beams 11 parallel to each other, each upper beam 11 The upper end is provided with upper frame steel plate 8, the lower end of upper frame steel p...

Embodiment 2

[0034] This implementation is further optimized on the basis of Embodiment 1, specifically:

[0035] Such as Figure 1 to Figure 5 As shown, the lower beam 4 and the upper beam 11 adopt a structure with small middle ends and large ends, and the gap width of the lower guide tensile assembly 3 is greater than the width of the middle part of the lower beam 4, and is smaller than the width of the two ends of the lower beam 4. The gap width of the pull assembly 9 is greater than the width of the middle part of the upper beam 11 and smaller than the width of the two ends of the upper beam 11 . The lower guide tensile assembly 3 and the upper guide tensile assembly 9 are arranged in an L-shape and reversely buckled on the outside of the pulley 10-1.

[0036] In this embodiment, the lower guide tensile assembly 3 constrains the lower beam 4 to slide in one direction, and at the same time constrains the vertical displacement of the lower beam 4 to prevent the lower pulley assembly 10 ...

Embodiment 3

[0038] Such as Figure 1 to Figure 5 As shown, the dustproof plate 12 is fixed on two upper frame steel plates 8 by bolts. The lower frame steel plate 6 is fixed on the ground by anchor bolts 1 . Curved surfaces with variable curvatures are arranged inside the lower harmonic orbit 2 and the upper harmonic orbit 7 . The structure of the lower pulley assembly 5 is the same as that of the upper pulley assembly 10. The upper pulley assembly 10 includes a pulley 10-1 and a bearing 10-2, and the edge of the bearing 10-2 has a boss. In this embodiment, the dust-proof plate 12 is installed to achieve the dust-proof effect, so as to prevent the normal operation of the mechanism from being affected by too much dust entering. Fixing by the anchor bolt 1 makes the mechanism more firmly installed on the ground. The curvature of the surface determines the size of the isolation period. By setting the curvature value accurately, an accurate isolation period can be obtained. The edge of th...

Description

technical field [0001] The invention relates to the field of shock isolation devices, and more particularly relates to a track shock isolation device for important cabinets. Background technique [0002] Important cabinets include railway important signal processing communication cabinets, aerospace important signal cabinets, important electrical control and communication cabinets for enterprises, etc. [0003] Since the last century, hundreds of earthquakes of magnitude 6 or above have occurred in my country, covering all provinces, autonomous regions and municipalities except Zhejiang, Hong Kong and Macau Special Administrative Regions. The number of earthquakes in my country is large and the intensity is large, and most of them are shallow earthquakes that occur on the mainland, which will cause great damage. According to the latest seismic intensity map, it can be seen that there are also a large number of railway lines, stations and airports in high-intensity areas in ...
