Simple track gauge pull rod device for tunnel construction

The utility model relates to a simple track gauge pull rod device for tunnel construction, and belongs to the technical field of tunnel construction. The simple rail gauge pull rod device for tunnel construction comprises a pull rod and two rail clamping assemblies. The rail clamping assemblies are arranged on the pull rod in a sleeving mode and symmetrically distributed on the two sides of the pull rod, the rail clamping assemblies connect the two steel rails together on the rail bottom so as to improve the transverse stability of the steel rails and improve the rail gauge keeping capacity of the steel rails, the rail gauge of the rails can be effectively kept by screwing the nuts, adjusting the positions of the rail clamping assemblies and clamping the two transverse rails, and the working efficiency is improved. The derailment risk in locomotive operation is reduced, the safe transportation efficiency of the locomotive is improved, and therefore the construction efficiency is improved. In addition, the dev
