The parking assist structure can enhance the braking stability of the spraying device when parking and prevent the frame structure from shifting and affecting the marking effect. A heating base 9 is fixed to the top of the frame structure. The heating base 9 is used to heat the paint in the paint box 10 to maintain the sprayability of the hot melt paint. The top of the heating base 9 is adapted to be clamped with a paint box 10, and the paint box 10 is loaded with marking paint.

[0025] The top of the paint box 10 is penetrated by a bearing 14 and connected with a high and low material suction pipe. The high and low material suction pipe includes a high-position pipe 15 and a low-position pipe 20. The connection between the high-position pipe 15 and the low-position pipe 20 forms a curved pipe portion 19. The high-position pipe 15 is connected with the low-position pipe 20 and both are inverted "V"-shaped hollow hard pipes. One end of the high-position pipe 15 is integrally formed with a wide-diameter pipe 16. A clamping section 17 is welded at the opening of the wide-diameter pipe 16. The clamping section 17 is a plurality of arc-surface clips arranged in a circular array. The surface of the clamping section 17 is threadedly connected with a locking nut 18. The locking nut 18 is used to lock the adjusted length of the high and low material suction pipes, thereby improving the convenience of adjusting the length of the high and low material suction pipes. A siphon channel is formed in the runway to transport the paint in the paint box 10 to the discharge pipe 201. During spraying, the valve 21 is opened, and the siphon phenomenon formed in the high and low suction pipes absorbs the paint from the inside of the paint box 10 and transports it to the discharge port of the discharge pipe 201, thereby spraying the paint to the gap formed by the roller brush 25, which is convenient for the line markers to mark the circular runway marking lines of the airport. A connecting plate 22 is fixed through the upper end of the discharge pipe 201, and a valve 21 is connected to the connection between the connecting plate 22 and the discharge pipe 201. A handle 23 is fixed to the top of the connecting plate 22, and a symmetrical roller brush 25 is movably connected to the lower end of the handle 23 through a traction rod 24, which is used to mark the circular runway marking lines on the airport runway.

[0026] Preferably, Figure 1 As shown, the connecting frame is an L-shaped bracket, and the connecting frame is used to fix the parking auxiliary structure on the top of the vehicle panel 1.

[0027] Preferably, Figure 1 As shown, a battery pack is detachably installed inside the heating base 9, and the top of the heating base 9 is grooved. The heating base 9 is used to heat the paint box 10, so that the paint in the paint box 10 is heated and remains in a sprayable state.

[0028] Preferably, Figure 1 As shown, a motor 11 is fixedly mounted on the lower side wall of the paint box 10, and a stirring rod is connected to the output end of the motor 11. The stirring rod runs through the interior of the paint box 10. When the motor 11 is started, the output end of the motor 11 drives the stirring rod to stir the paint inside the paint box 10.

[0029] Preferably, Figure 1 As shown, a side wall of the paint box 10 is connected to a feed pipe 12 , and a top cover 13 is threadedly connected to the top of the feed pipe 12 . The top cover 13 is used to block the opening of the feed pipe 12 .

[0030] Preferably, Figure 1 As shown, the discharge port of the discharge pipe 201 is directly opposite to the gap formed by the sides of the two roller brushes 25, which can improve the uniformity of the paint spraying of the marking line.

[0031] Working principle: When in use, the frame structure is locked by the self-locking roller 2 brake to keep the vehicle plate 1 in a fixed state. By starting the telescopic cylinder 6, the telescopic cylinder 6 drives the telescopic rod 7 to squeeze the vacuum suction cup 8 downward, so that a vacuum is formed between the vacuum suction cup 8 and the ground. The vacuum suction cup 8 is pressed tightly by atmospheric pressure to assist the frame structure braking. By connecting the power supply of the heating base 9, the paint in the paint box 10 can be heated to keep the paint in the paint box 10 in a sprayable state. By starting the motor 11, the output end of the motor 11 drives the stirring rod to rotate, which can stir the paint in the paint box 10 to avoid uneven heating of the paint. The opening of the material pipe 201 opens the valve 21, and the paint in the paint box 10 can be transported to the high and low material suction pipes through the siphon phenomenon, and then transported to the discharge pipe 201 by the high and low material suction pipes. The discharge pipe 201 discharges the paint into the gap formed between the two roller brushes 25. The operator uses the center of the bearing 14 as the rotation center and the length of the high and low material suction pipes as the radius, and pulls the roller brush 25 to rotate through the handle 23 to mark the circular runway line on the airport runway ground. By setting the high and low material suction pipes as hard pipes, the consistency of the displacement radius of the roller brush 25 can be always maintained during the marking process, which is conducive to reducing the difficulty of marking the circular marking line.
