[0098] When the engineering vehicle driving device moves to the specified position, the mechanical arm 102 drives the carrier 103 to move above the guardrail column, and then the image collector 202 collects the image of the guardrail column below the carrier 103, and feeds the image to the control terminal 104, then the control terminal 104 divides and extracts the features of the image, and compares the features, so as to determine the position of the guardrail column by image recognition technology, and then adjust the position of the carrier 103 by the mechanical arm 102 according to the determination result, to complete the preliminary positioning between the carrier 103 and the guardrail column.

[0099] When the preliminary positioning is completed, the first sleeve 201 is sleeved on the guardrail column by the mechanical arm 102 using the carrier 103, when the sleeving action of the first sleeve 201 is completed, the output shaft of the third motor 803 drives the gear 802 to rotate, the rotating gear 802 drives the correction frame 801 connected with it to rotate, the rotating correction frame 801 drives the connecting rod 804 to move by the sliding block 805, the moving connecting rod 804 drives the pressure wheel 806 to extrude and clamp the outer wall of the guardrail column, so as to correct the carrier 103 and the guardrail column, and center the first sleeve 201 and the guardrail column, after the centering process is completed, the third motor 803 drives the gear 802 to rotate reversely, so as to release the clamping of the guardrail column, and reset the correction frame 801, the connecting rod 804, the sliding block 805 and the pressure wheel 806.

[0100] After the reset action is completed, the first sleeve 201 is separated from the guardrail column by the mechanical arm 102 using the carrier 103, and then the carrier 103 is rotated by the mechanical arm 102, the position of the first sleeve 201 and the second sleeve 301 is exchanged, so as to move the second sleeve 301 above the guardrail column, and then the second sleeve 301 is sleeved on the guardrail column by the carrier 103 driven by the mechanical arm 102, when the sleeving action is completed, the inner sleeve 303 is rotated by the output shaft of the first motor 302, and the rotating inner sleeve 303 brushes and cleans the sundries adhered to the surface of the guardrail column.

[0101] When the brushing action is completed, the second sleeve 301 is separated from the guardrail column by the mechanical arm 102 using the carrier 103, and then the carrier 103 is rotated to exchange the positions of the second sleeve 301 and the cover 401, so that the cover 401 is moved above the guardrail column, and then the cover 401 is sleeved on the cleaned guardrail column by the mechanical arm 102 driving the carrier 103.

[0102] When the sleeving action is completed, the fourth motor 408 drives the material collecting roller 405 to rotate, and the rotating material collecting roller 405 winds the used reflective film roll 407 and moves the reflective film on the reflective film roll 407 between the rotating rollers 403.

[0103] When the winding action is completed, the first electric push rod 7 drives a connecting frame 503 to move, and the moving connecting frame 503 drives the flexible clamping jaw 504 and the flexible suction cup 601 to contact the reflective film on the reflective film roll 407. When the action of the first electric push rod 7 is completed, the piston block 509 drives the air in the piston tube 507 to be extruded by the piston rod of the second electric push rod 508, so that the air is injected into the flexible clamping jaw 504 by the air collecting pipe 506 and the first air guide pipe 505, and then the flexible clamping jaw 504 drives the flexible suction cup 601 to adhere to the reflective film under the action of the air. When the action of the second electric push rod 508 is completed, the air in the flexible suction cup 601 is extracted by the second air guide pipe 602 by the air pump 603, so that the reflective film is sucked by the flexible suction cup 601.

[0104] When the flexible suction cup 601 suction action is completed, the second electric push rod 508 drives the piston block 509 to reset, so that the air in the flexible clamping jaw 504 is extracted, the flexible suction cup 601 is initially separated, and the two sides of the reflective film are separated from the reflective film roll 407, so that the reflective film is easily taken off.

[0105] When the action of the second electric push rod 508 is completed, the first electric push rod 7 drives the connecting frame 503, the flexible clamping jaw 504, and the flexible suction cup 601 to reset, so that the reflective film is taken off from the reflective film roll 407. When the action of the first electric push rod 7 is completed, the support frame 501 and the taken-off reflective film are flipped by the output shaft of the second motor 502.

[0106] When the action of the second motor 502 is completed, the actions of the first electric push rod 7 and the second electric push rod 508 are repeatedly performed to press and paste the reflective film on the guardrail column, thereby completing the replacement operation of the reflective film.

Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
