This device first places the transport carrier horizontally on the ground, then hoists the industrial robot to the upper side of the loading plate through the hoisting equipment, and tries to make the chassis of the industrial robot located in the middle of the loading plate, and then rotates the hand wheels and threaded rods around respectively, and the rotating threaded rods drive the mounting blocks to slide inward along the mounting grooves, thereby driving the limit plates and limit blocks close to the industrial robot, and the chassis of the industrial robot can be firmly restricted to the loading plate through the limit plates and limit blocks around. It avoids the need to align the screw holes on the chassis of the industrial robot with the screw holes on the loading plate one by one when hoisting the industrial robot to the upper side of the loading plate, and then fix the chassis of the industrial robot to the transport carrier by bolt connection, and remove these bolts after transporting to the installation site.";
