The utility model provides a damping device for platform floats and holds in palm installation, includes: piston ceptor, suit are at the outside sleeve of piston ceptor, wherein, the horizontal snubber block of several has been placed along the circumference position uniformly in the top of piston ceptor, and the lower partial the same vertical snubber block of center pin through connection several structure size of piston ceptor is at the inside heating device that is provided with of vertical snubber block. The utility model discloses utilize the temperature variation to the influence of supporting shoe, improve the temperature, upper portion engineering chunk float hold in the palm install the jacket on the time, not only can further increase the compression displacement of vertical bolster part for insert the point part and dwindle to contacting each other between the two gradually with steel cylinder part distance, solved and produced the collision problem of steel to the steel between the structure thing, and the installation procedure that has still significantly reduced has reduced construction cost.
