Summary: | The invention relates to the technical field of mining construction instruments, in particular to a drilling pay-off mechanism. The drilling pay-off mechanism comprises a telescopic scale assembly, an angle identification measuring assembly is fixedly installed on one side of the middle section of the telescopic scale assembly, a construction pay-off assembly is fixedly installed in the center of the top of the angle identification measuring assembly, the two ends of the telescopic scale assembly are each provided with a fine adjustment assembly, and the top of the center of the telescopic scale assembly is fixedly provided with a horizontal indication component. According to the drilling pay-off mechanism, the principle is simple, and using is convenient; a drill hole can be quickly paid off by calibrating the included angle between the drill hole and the roadway on site, and the problems that paying off is tedious and low in precision through a total station or a compass are effectively solved; and when the |
