The invention relates to a concrete vibrating leveling device which comprises a spliced rail. A sliding plate is arranged on the spliced rail, the lower end face of the sliding plate is provided with at least two rollers correspondingly clamped to the spliced rail, the upper end face of the sliding plate is fixedly provided with a positioning lifting frame, the positioning lifting frame comprises a guide rod and a lead screw, the upper end of the guide rod and the upper end of the lead screw are each fixedly provided with an upper end cap, the upper end caps are fixedly provided with a first motor, a shaft of the first motor is connected with the lead screw, the guide rod is provided with a left sliding sleeve, the lead screw is provided with a right sliding sleeve, a cam box is arranged in front of the left sliding sleeve and the right sliding sleeve, a second motor is fixed to the cam box, a shaft of the second motor is connected with transverse rods transversely arranged in the cam box, the transverse rods correspond to through holes and are each sleeved with an ejector rod cam, and vibration bars are arranged in the through holes in a penetrating mode. According to the device, concrete is tamped through the vibration bars by means of the ejector rod cams fixed to the transverse rods, tamping efficiency of the vibration bars is improved, and the aim that vibration and tamping of the vibration bars are carried out at the same is achieved.
