SUMMERY OF THE UTILITY MODEL

An object of the utility model is to solve the problem that exists among the prior art, provide an embedded vibration isolation device, can reduce assembled track structure's overall cost, can satisfy the needs of traveling of the train of different loads, make things convenient for the orbital assembly of assembled.

The utility model discloses a realize above-mentioned purpose, realize through following technical scheme:

the embedded vibration isolation device comprises an elastic base plate, wherein a plurality of through holes are vertically formed in the elastic base plate, clamping grooves are formed in the inner walls of the through holes, elastic columns are arranged in the through holes, clamping blocks matched with the clamping grooves are arranged on the outer walls of the elastic columns, the heights of the elastic columns are larger than the thickness of the elastic pad, and the thicknesses of the clamping blocks are smaller than the heights of the clamping grooves.

Preferably, a gap is left between the outer wall of the elastic column and the inner wall of the through hole.

Preferably, the clamping groove is an annular groove.

Preferably, the fixture block is an annular block.

Preferably, the outer edge of the bottom of the fixture block is provided with a chamfer.

Contrast prior art, the beneficial effects of the utility model reside in that:

the utility model has the advantages that the elastic column is embedded on the elastic backing plate, which is convenient for transportation, the utility model can be directly laid without installing the elastic column on the construction site, which is convenient for assembling the assembly type track; the elastic column can slide up and down in the through hole, the upper position and the lower position of the elastic column can be automatically adjusted according to the surface states of the assembled track plate on the upper side and the base plate on the lower side, so that the upper end of the elastic column is abutted against the assembled track plate, the bottom end of the elastic column is abutted against the base plate, and the assembled track plate and the base plate are in point contact with each other in a small area, the smoothness requirements on the surfaces of the assembled track plate on the upper side and the base plate on the lower side can be reduced, and the overall cost of the assembled track structure can be reduced; when the train is lightly loaded or unloaded, the elastic column mainly provides buffer, so that the travelling comfort of the train is ensured by smaller rigidity; when the train is heavily loaded, the elastic column is compressed to the through hole, and the elastic column and the elastic base plate simultaneously provide buffering, so that the running requirements of trains with different loads can be met by ensuring the running stability and safety of the train with higher rigidity.
