A measuring method for the device applicable to measuring the outer edge curvature radius of the arc gate panel according to claim 5, characterized in that, It includes the following steps: S1, Preparation: Install fixed pulleys on both sides of the top section of the radial gate, and pass the towing rope through the fixed pulleys; clean the radial gate panel; at this time, the radial gate is in a vertical state; S2, Install the vehicle frame, the wheels (14) are in rolling contact with the radial gate panel, and the guiding wheels of the guiding mechanism (2) are in rolling contact with the side edge of the radial gate panel; at this time, an adsorption force is generated between the longitudinal adsorption magnets (42) and the radial gate panel, and an adsorption force is generated between the lateral adsorption magnets (41) and the side edge of the radial gate panel; at this time, the vehicle frame (1) is subjected to adsorption forces in the horizontal direction and the side direction and will not fall off the radial gate panel; S3, Install the towing rope, connect one end of the towing rope on one side of the top section of the radial gate to the vehicle frame (1), and the other end of the towing rope on this side extends over the top of the radial gate panel to the back side of the radial gate panel; S4, Install the tape measure, straighten the scale roll of the tape measure, insert it along the measuring guide plate (32), and then rotate the crank to push the screw rod to make the clamping plate gradually contact and lock with the scale roll; before locking, the zero position on the scale roll corresponds to the zero scale groove on the measuring guide plate (32); S5. Measurement: Pull the towing rope on the back side of the arc gate panel. The towing rope pulls the vehicle frame (1) to roll vertically upward and stop when it reaches the measurement point. Straighten the tape measure to the outer edge of the arc gate panel and read the measured value. During the measurement, the surveyor is located at the hinge center position of the arc working gate. S6. Repeat S2 - S5 to measure the radius of curvature on the other side of the arc gate.
