The invention relates to the technical field of rubber support detection, and discloses a shock insulation rubber support deformation detection device which comprises a heat insulation box, the interior of the heat insulation box is hollow, one side of the heat insulation box is open, first hydraulic rods are symmetrically arranged in the heat insulation box, and a heat insulation door is slidably connected to one side of the opening of the heat insulation box. An air extraction opening is formed in the side, away from the heat insulation door, of the heat insulation box, a communicating
pipe communicating with the air extraction opening is installed on the surface of the heat insulation box, the other end of the communicating
pipe communicates with an air storage cylinder installed at the top of the heat insulation box, and an air extraction
piston is slidably connected into the air storage cylinder; one end of the air exhaust
piston is fixedly connected with a movable rod which penetrates through one end of the air storage cylinder and extends to the outside,
cold air in the heat insulation box is pumped into the air exhaust
piston to be stored in a heat preservation mode through sliding of the air exhaust piston in the air storage cylinder, and when deformation detection is conducted on the shock insulation rubber support next time, the
cold air stored in the air storage cylinder is sent back to the heat insulation box. The purpose of mixed heat exchange between
cold air and gas in the heat insulation box is achieved.
