Further, based on the above embodiment, the damper element can be, but is not limited to, the wire rope isolator 2. The wire rope isolator 2 can be used to generate large elastic deformation to buffer external shock and improve the buffering effect.

2 is a view showing a state of use of a vibration damping platform according to Embodiment 2 of the present invention. As shown in Figure 2, during use, in some cases (such as, but not limited to, the damping platform is applied to a mobile CT scanner, when the mobile CT scanner is used after the end of transportation arrives at the destination) Temporarily releasing the vibration damping capacity of the vibration damping device and using it as a rigid connecting member, a fixing block 7 is inserted into the wire rope isolator 2, and the ejector pin 4 is screwed into the fixing block 7, and the ejector pin 4 is worn at one end. The first support base 1 and the other end are matched with the second support base 3 or the wire rope isolator 2 . When in use, the ejector lever 4 can be rotated by the torque wrench 6 to make the ram 4 on the second support base 3 or the wire rope isolator 2, thereby eliminating the vibration damping performance of the wire rope isolator 2, so that the first support base 1 Forming a rigid connection with the second support base 3. However, during the next transport, the fixed block 7 is removed and the damping platform is restored to the effect of damping.

The fixed block 7 may be an elongated rectangular block.

Using the torque wrench 6 to rotate the ram 4, it is possible to prevent damage to the wire rope isolator 2 due to excessive force.
