Crane gauge deviation value automatic monitoring device

The utility model discloses a crane gauge deviation value automatic monitoring device. A first macro laser ranging sensor and a second macro laser ranging sensor located on the outer side of paired tracks and used for correspondingly measuring the linear distance thereof from the outer side surface of each track are fixedly arranged on the outer sides of end beams on the two sides of a crane capable of reciprocating along the length direction of the paired tracks extending linearly; a laser reflection plate is located at one end of the track; a single chip is arranged on the crane, and a long-distance laser ranging sensor for measuring the linear distance thereof from the laser reflection plate is fixedly arranged on the crane; the signal output ends of the first macro laser ranging sensor, the second macro laser ranging sensor and the long-distance laser ranging sensor, a signal input end of a display screen and a power output port of a power module are connected with corresponding ports of the single chip;
