Gauge supporting rod for ballastless track construction

The invention discloses a gauge supporting rod for ballastless track construction. The gauge supporting rod comprises a first connecting rod, a second connecting rod and a bushing, wherein one end of the first connecting rod and one end of the second connecting rod are provided with external threads; internal threads are arranged in the bushing; the bushing is in threaded connection with the first connecting rod and the second connecting rod respectively; the gauge supporting rod is characterized in that the other end of the first connecting rod is provided with a first clamping member, wherein the other end of the second connecting rod is provided with a second clamping member; the first clamping member and the second clamping member are both U-shaped; the second clamping member is provided with a through hole; a sleeve is arranged on the through hole; a screw is arranged in the sleeve and is matched with the sleeve. The gauge supporting rod has the advantages that the clamping members are arranged on the gauge rod by using the characteristic that the length of the gauge rod can be adjusted, so the clamping members are fixedly arranged on a ditch wall and a tool track respectively, the impact caused to a track panel by concrete construction and vibration during vibration are reduced, and the qualification rate of the gauge change rate is improved. The invention also has the advantages of low manufacturing cost and easiness and convenience in use.
