The utility model relates to the railway construction field, especially relates to a double block-type sleeper sleeve pipe center distance detection tool comprising a measuring rod, a measuring fixing assembly, and a measuring sliding assembly. The measuring fixing assembly is cooperated with the measuring rod, and can be fixedly disposed on the measuring rod. The measuring sliding assembly is cooperated with the measuring rod, and a magnetic grid electronic display of the measuring sliding assembly can be used to measure the relative displacement of the measuring sliding assembly and the measuring rod by the electronic measuring way. The detection tool provided by the utility model cooperated with a specially-produced measuring clamp can be used to measure the distance between bottom studs of outer sides of two rail supporting grooves of the sleeper. The double block-type sleeper sleeve pipe center distance detection tool is advantageous in that the detection tool cooperated with the specially-produced measuring clamp can be used to measure the distance between the bottom studs of the outer sides of two rail supporting grooves of the sleeper, and the measurement precision can reach 1/10 of the required detected essential factor precision, and the GAGE R&R is less than 20%; the operation is simple and stable, and the display is visible, and the detection tool is suitable for the outdoor operation.
