Further, the vibration isolation rubber of described damping element is low hardness vibration isolation rubber.
During use, be fixed together in the chassis of receiving machine and vibration reduction support seat upper flange, the base of vibration reduction support seat is fixedly connected with the basis on ground, the overall effect being realized vibration damping by damping element of receiving machine.
When needs regulate levelness, by the extending amount regulating the lock bolt on three extension sleeves to carry out adjustable telescopic rod, detection level degree is carried out by the leveling instrument of upper flange upper surface, after levelness meets the requirements, screw lock bolt, the upper surface of the chassis of receiving machine and the upper flange of supporting base is fixed together.
Beneficial effect:
1, vibration reduction support seat of the present invention can realize good effectiveness in vibration suppression to receiving machine, and centering, dither have good neutralization effect; And the levelness of supporting base can be adjusted easily, guarantee that receiving machine is in best working state.
2, damping element of the present invention is formed by spring, bolt and vibration isolation rubber sulfuration, and it is shaping and manufacturing process simple, and cost is low, and the two ends sulfuration of damping element has bolt, is convenient to realize being connected with upper flange and base.
3, the spring in damping element of the present invention and vibration isolation rubber can be formed and support each other and protection, and overall bearing capacity is good, long service life.
