The invention relates to the technical field of subway engineering vehicles, in particular to a rail grabbing device and a rail grabbing method for a subway engineering vehicle. The rail grabbing device comprises a lifting assembly and a clamping jaw assembly. The lifting assembly is installed at the lower end of the engineering truck and comprises a lifting motor and a push rod, and the push rod is installed at the bottom end of the lifting motor. The clamping jaw assembly comprises a shell, a clamping jaw motor and clamping jaws, the upper end of the shell is rotationally connected with the lower end of the push rod, the clamping jaw motor is fixed in the shell, the clamping jaws comprise the left clamping jaw and the right clamping jaw, the left clamping jaw and the right clamping jaw are rotationally connected with the shell and are symmetrically arranged, the clamping jaw motor can drive one clamping jaw to rotate, and the clamping jaw motor can drive the other clamping jaw to rotate. The top of the inner side of the left clamping jaw is meshed with the top of the inner side of the right clamping jaw. According to the rail grabbing device, the working environment of operators is improved, the clamping jaws are prevented from being damaged when a vehicle turns, and the service life of the rail grabbing device is prolonged.
