The invention discloses an anti-impact slide device which comprises a sliding plate, a buffer device arranged on the sliding plate, and a steel plate with one end connected with the back side of the sliding plate and the other end connected with a civil foundation embedded part. The buffer device comprises a sleeve, a spring and a guide sleeve which are arranged in the sleeve, a press plate used for fixing the spring and the guide sleeve into the sleeve, and an impacting plate arranged at the upper end of the sleeve and connected with the guide sleeve. The guide sleeve is arranged at the upper end of the spring. The anti-impact slide device has the advantages that the slide device can greatly reduce impact to a slide and overturning moment caused by impact to a slide support foundation, accordingly a civil foundation and the slide of a slide support are protected, halt production caused by looseness and vibration fracturing of the civil foundation is avoided, and the anti-impact slide device is compact in structure, easy to manufacture, resistant to impact and easy to mount and dismount.
