Stress monitoring device for floating slab vibration isolator

The invention discloses a stress monitoring device for a floating slab vibration isolator. The device comprises a vibration isolator inner cylinder (1), a spring (2) in the vibration isolator inner cylinder and an inner cylinder cover (3), and further comprises a stress gage (4) arranged between the spring and the inner cylinder cover, a signal terminal (6) arranged on the inner cylinder cover andan external receiving apparatus. The stress gage is connected with the signal terminal through a wire, the stress gage induces the stress condition of the floating slab vibration isolator in real time and transmits a signal to the signal terminal, the signal terminal is arranged on the inner cylinder cover and coupled to the external receiving apparatus through a wired or wireless mode, and the external receiving apparatus directly observes the stress condition of the floating slab vibration isolator. The stress monitoring device for the floating slab vibration isolator has the advantages that the structure is simple
