Device for dismantling concrete support by utilizing resonance principle

The utility model provides a device for dismantling a concrete support by utilizing the resonance principle, which comprises a vibration exciter, a clamping piece and a slag stopping device, the clamping piece is used for clamping the concrete support to be dismantled, the vibration exciter is fixedly arranged on the clamping piece, the vibration exciter is used for generating resonance with the concrete support, and the slag stopping device is arranged on the clamping piece. And the slag stopping device is arranged below the concrete support. The frequency of the vibration exciter is adjusted to be the natural vibration frequency of the concrete support through the sine wave signal generator, the concrete support and the vibration exciter are tightly connected through the clamping piece, and therefore resonance of the concrete support is caused by the vibration exciter, the purpose of dismantling the concrete support is achieved, stripped concrete fragments fall on the baffle, and the concrete support is not
