Railway track detection device

A railway track detection device relates to the technical field of rail detection and is characterized in that the number of clamping mechanisms is two, two connecting mechanisms are mounted between the two clamping mechanisms, a groove is formed in the rotating end of each connecting mechanism, a placing mechanism is mounted in each groove, and a power switch group is mounted at the placing end of each placing mechanism; according to the railway track detection device, the railway track detection device is installed on the rails through the clamping mechanism, adjustment can be conducted according to the standard rails and the narrow rails, the railway track detection device is driven to move through the clamping mechanism, the distance between the two rails is detected in the moving process, and the detection accuracy is improved. And the numerical control terminal for comparison is placed through the placement mechanism, so that a worker can check the numerical control terminal in time conveniently and is
