The invention discloses a rail protection device with alarm, which comprises two rails. The midpoints of the two rails are used as symmetric centers, protection boxes are arranged on the rail in a bilateral symmetry and abutting mode, a transmission block abuts against the side, away from the symmetric center, of the rail, a control box is slidably arranged on the side, away from the symmetric center, of the transmission block, an alarm cavity and a power generation cavity are formed in the protection box, and the alarm cavity is located above the power generation cavity. The protection box islaid on the rail, a construction vehicle can directly pass through the rail, the elastic guide rail is arranged at the top, the construction vehicle is pressed to generate electricity, when a train arrives, the protection box is lifted up, and the force generated by rotating the protection box drives the alarm to make a sound to remind construction personnel that the train arrives.
