[0031] The present invention is described in detail below in conjunction with the accompanying drawings of the specification, but it should be noted that the implementation of the present invention is not limited to the following embodiments.

[0032] See Figure 1-Figure 3A device for automatically replacing ground markings on airport runways, comprising a three-color marking cloth 1, a control shell, a transmission mechanism 2, a chain 3, a limit switch 5, a transmission shaft assembly 4, a motor 6, and a limit plate 9. The motor 6 is connected to the transmission mechanism 2, the transmission mechanism 2 is connected to the transmission shaft assembly 4, the motor 6 drives the transmission shaft assembly 4 to rotate through the transmission mechanism 2, the transmission shaft assembly 4 is connected to the chain 3, the three-color marking cloth 1 is fixedly connected to the chain 3, the three-color marking cloth 1 is arranged in the control shell, a display window 17 is opened on the control shell, the three-color marking cloth 1 is arranged in the display window 17, and the three-color marking cloth 1 displays only one color within the display window 17. Three limit plates 9 are fixedly connected to the chain 3, the limit plates 9 are arranged in parallel, a baffle 11 is fixedly connected to the limit plate 9, and the limit switch 5 is fixedly connected to the control shell. The limit plate 9 rotates with the chain 3. When the limit plate 9 moves to the position of the limit switch 5 with the chain 3, the contact of the corresponding limit switch 5 is triggered, the motor 6 stops running, and the chain 3 stops running. At this time, a color is displayed in the range of the display window 17.

[0033] The transmission shaft assembly is used to support and drive the three-color marking cloth 1 to rotate, and at least two groups are provided. Figure 1 As shown, there are three groups of transmission shaft assemblies, two groups of transmission shaft assemblies support the three-color logo cloth 1, and the middle group of transmission shaft assemblies is close to the display window 17, supporting the three-color logo cloth 1 close to the display window 17. The transmission shaft assembly 4 includes a transmission shaft 41, a support wheel 42, a transmission gear 43, and a bearing sleeve 44. More than one support wheel 42 can be fixedly connected to the transmission shaft 41 by bolts; the transmission gear 43 is fixedly connected to both ends of the transmission shaft 41; the bearing sleeve 44 and the transmission shaft 41 are connected by bearings, and the transmission sleeve is fixedly connected to the mechanism groove 12 of the regulating shell by bolts. The transmission gear 43 is meshed with the chain 3, and the chain 3 rotates with the rotation of the transmission gear 43. The transmission mechanism 2 is a belt, the output shaft of the motor 6 is connected to the belt, the transmission shaft 41 extends out of the mechanism groove 12, and the belt is connected to the transmission shaft 41. The rotation and stop of the motor 6 drive the rotation and stop of the transmission shaft 41 through the belt. The belt is arranged on the outside of the mechanism groove 12, and the protective cover 16 is arranged outside the belt. The protective cover 16 is fixedly connected to the mechanism groove 12 by bolts to protect the belt.

[0034] The control housing includes a mechanism groove 12, a top plate 13, a bottom plate 14, and a support plate 8. The top plate 13 is fixedly connected to the mechanism groove 12 at both sides by bolts. The mechanism groove 12 is connected to the transmission shaft assembly. The two ends of the support plate 8 are fixedly connected to the mechanism groove 12, and the three-color marking cloth 1 is arranged between the support plate 8 and the top plate 13. The support plate 8 plays the role of supporting the three-color marking cloth 1 so that it is flat at the display window 17. The bottom plate 14 is fixedly connected to the bottom of the mechanism groove 12. The controller assembly 7 and the motor 6 are fixed to the bottom plate 14 with bolts.

[0035] The three-color identification cloth 1 is an annular cloth strip. The three-color identification cloth 1 is made of red, white and camouflage cloths welded or pressed into an integral closed annular shape. The support wheel 42 is located inside the three-color identification cloth 1. The two side edges of the three-color identification cloth 1 are fixedly connected to the chain 3 by springs or bolts and are located in the middle of the two side chains 3, so that the three-color identification cloth 1 can be abutted against the display window 17. Correspondingly, there are three limit plates 9, namely, limit plate A91, limit plate B92, and limit plate C93. The baffles 11 thereon correspond to a limit switch 5 respectively. When the limit plates A91, limit plates B92, and limit plates C93 trigger the corresponding limit switches 5, the display window 17 displays a color respectively. The fixing plate 10 is fixedly connected between the mechanism grooves 12 on both sides, and three mounting brackets 15 are respectively fixed on the fixing plate 10. The limit switch 5 is fixed on the mounting bracket 15. The position of the limit switch 5 corresponds to the baffle 11 on the limit plate 9, so that the baffle 11 can trigger the contact of the limit switch 5. The operation of the three-color marking cloth 1 will not scratch the limit switch 5, and will not affect the limit plate 9 triggering the limit switch 5.

[0036] When the display window 17 needs to change the display color, the motor 6 runs to drive the transmission shaft 41 to rotate through the belt, and drives the three-color identification cloth 1 to run through the support wheel 42 and the chain 3. When the baffle 11 of the limit plate A91 triggers the contact of the corresponding limit switch 5, the motor 6 stops, the chain 3 stops running, and one of the three colors of the three-color identification cloth 1 stops at the display window 17. If it is necessary to change to other colors, the corresponding limit switch 5 is triggered to stop the three-color identification cloth 1 at the corresponding position.

[0037] The controller component 7 is connected to the limit switch 5 and the motor 6. The control part of the device includes a PLC controller, color selection buttons K1, K2, K3, maintenance button KX, and relay KM. The three limit switches 5 are limit switches T1, T2, and T3, which correspond to the color selection buttons in sequence. The limit switches T1, T2, and T3 are connected to the PLC controller. After the switch KZ is turned on, the PLC controller starts to work. At this time, the PLC controller has not received the command and the relay will not be attracted. After pressing the color selection button K1, the relay KM is attracted and the motor M starts to run. When the limit switch T1 is triggered, the relay KM is released, the motor M stops running, and the three-color marking cloth 1 remains in the first station. Similarly, when the color selection button K2 or the color selection button K3 is pressed, the motor M will stop at the corresponding station position. When maintenance is required, the maintenance button KX can be pressed to control the motor to rotate to any position and keep it, which is convenient for maintenance. The color selection buttons K1, K2, K3, and the maintenance button KX can be operated at a certain distance by remote control.
