Shield hob torque detection device

The utility model relates to the technical field of torque detection devices, in particular to a shield hobbing cutter torque detection device, which comprises a fixed bottom plate, a support frame, a guide frame, a sliding plate, a ball screw, a support seat and a clamping block, and is characterized in that a shaft of a shield hobbing cutter is clamped with a clamping groove on a clamping clamping shaft, and then a locking thread bushing is screwed down, so that the shield hobbing cutter can be fixed. According to the shield tunneling machine hobbing cutter detection device, the clamping clamping shaft is driven to clamp the shaft of the shield tunneling machine hobbing cutter, so that the shaft of the shield tunneling machine hobbing cutter can be fixed, and the situation that the shaft of the shield tunneling machine hobbing cutter shakes to affect the detection result in the detection process is prevented; therefore, the clamping blocks on the two sides can clamp a cutter ring of the shield tunneling mac
