Abstract
The present invention relates to the field of construction equipment technology, and in particular to an anti-seismic bearing for construction, comprising a cylinder, a guide mechanism, and a plurality of cones, wherein the axial direction of the cylinder is set as a first direction; one end of a piston rod along the first direction can be slidably arranged in the cylinder, and a fluid is provided in the cylinder; a plurality of cones are sequentially arranged in the first direction and can slide in the first direction, a spiral piece is provided between each of two adjacent cones, and the spiral piece is located on the inner side of the corresponding cone, and the spiral piece is elastic and can rotate; the guide mechanism can make the two adjacent cones approach or move away from each other in the first direction and rotate the spiral piece. The guide mechanism causes the spiral piece to rotate, and the rotation of the spiral piece can promote the flow of the fluid in the cylinder, so that the fluid heated by the piston rod is quickly dispersed, and the cone is provided, and when the two adjacent cones are in contact, the conveying capacity of the spiral piece located on the inner side of the cone is improved, so that the heat distribution inside the cylinder is more uniform.
