The utility model discloses a nondestructive test workstation of arcwall face, comprising a base plate, the threaded pole of top movable mounting of bottom plate, and the top of bottom plate is provided with the roof, the top of threaded rod insert in the inner chamber of roof with bottom fixed connection from the driving wheel, the top fixed mounting of roof has the motor, with the top fixed connection of action wheel during the output shaft of motor runs through the roof and extends to the inner chamber of roof, and action wheel and from the driving wheel meshing. The utility model discloses a set up motor drive action wheel and rotate, drive driven round and rotate when the action wheel rotates to driving the threaded rod and rotating, because connecting rod and clamping device's restriction when the threaded rod rotates, therefore the nut can't rotate, thereby it descends to make the nut drive clamping device, presss from both sides the pipeline in the arc wall tightly, thereby avoids leading to the detection of pipeline to cause the deviation examining time measuring pipeline emergence roll.
