The invention discloses a drilling rod rotating speed torque detection device, which comprises a base, a driving motor, a loading gear box, a first test position, a second test position, a rear gear box and a bending apparatus, wherein the first test position and the second test position are parallelly arranged between the loading gear box and the rear gear box, both the first test position and the second test position are sequentially provided with a gear-type coupler, a drilling rod male connector, a drilling rod female connector and a shaft base from the rear gear box forward , the first test position is further provided with a torque rotating speed sensor, the second test position is further provided with a universal drive shaft which avoids a drilling rod from inclining, and the bending apparatus used for bending the drilling rod is arranged between the drilling rod male connectors and the drilling rod female connectors. The drilling rod rotating speed torque detection device can simulate bending conditions of the drilling rod in use through the bending apparatus, and two drilling rods can be tested simultaneously, thereby improving the test efficiency.
