Description

[0002] National land space planning is a systematic arrangement of the national land space within a certain area to ensure that the land in the area is used reasonably. For example, the activity space for motor vehicles and pedestrians is planned by marking lines on the road, and corresponding traffic signs are marked on the corresponding roads to guide people's actions. The existing marking devices are mostly designed for longer guide lines such as lane dividing lines and indicator markings, and there is a lack of devices for marking road traffic signs such as turn lines. When marking traffic signs, staff are required to pre-paste tapes and other items around the traffic signs to cover the area around the road signs, or place pre-made road sign shells at the positions where marking is required to prevent paint from being sprayed outside the traffic signs.

DETAILED DESCRIPTION

[0031] The technical solution is further described below in conjunction with specific embodiments. It should be noted that the words indicating directions such as up, down, left, and right mentioned in this document are only for the positions of the structures shown in the corresponding drawings. The serial numbers assigned to the components in this document, such as first, second, etc., are only used to distinguish the objects described and do not have any order or technical meaning.

[0032] When marking traffic signs, workers need to stick tape or other items around the required traffic signs in advance to cover the area around the road signs so that the inside of the tape is formed into the shape of the traffic signs to be marked, or place a pre-made road sign shell at the location where the marking is required to prevent paint from being sprayed outside the traffic signs when marking, causing the shape of the traffic signs to change. After that, workers use a spray gun to spray the corresponding position and remove the tape after the spraying is completed, making the arc efficiency low and the process very cumbersome and troublesome (the following takes the U-turn line in the traffic sign as an example).

[0033] Embodiment 1: A rapid demarcation device for national land space planning, such as Figure 1-Figure 7 As shown, it includes a frame 1, a storage tank 2 is arranged on the upper side of the frame 1, a rotating shaft 3 is rotatably connected to the front side of the frame 1, an electric telescopic frame 4 is fixedly connected to the upper end of the rotating shaft 3, a discharge shell 5 is fixedly connected to the telescopic end of the electric telescopic frame 4, an elastic two-way telescopic rod 6 is fixedly connected to the front of the lower side of the discharge shell 5, and the elastic two-way telescopic rod 6 is biased to the left, and an adjustable two-way telescopic rod 7 is fixedly connected to the rear of the lower side of the discharge shell 5, the two telescopic ends of the elastic two-way telescopic rod 6 and the two telescopic ends of the adjustable two-way telescopic rod 7 are both oriented left and right, the fixed part of the elastic two-way telescopic rod 6 and the fixed part of the adjustable two-way telescopic rod 7 are connected by a hose, and the elastic two-way telescopic rod 6 and the adjustable two-way telescopic rod 7 are connected The two ends of the two-way telescopic rod 7 are filled with compressible gas. When the telescopic end of the two-way telescopic rod 7 moves, the gas in the two-way telescopic rod 7 enters the elastic two-way telescopic rod 6 through the hose. The rear part of the lower side of the blanking shell 5, the telescopic end of the elastic two-way telescopic rod 6 and the telescopic end of the adjusting two-way telescopic rod 7 are all fixedly connected with a sliding frame 8. The diameter of the fixed part of the elastic two-way telescopic rod 6 is smaller than the diameter of the fixed part of the adjusting two-way telescopic rod 7. When the telescopic end of the elastic two-way telescopic rod 6 moves, the distance moved by the sliding frame 8 on the elastic two-way telescopic rod 6 is greater than the distance moved by the sliding frame 8 on the adjusting two-way telescopic rod 7, ensuring that the two sliding frames 8 on the adjusting two-way telescopic rod 7 are located at the two sliding frames on the elastic two-way telescopic rod 6. The two spray guns 9 on the front side are initially oriented toward the center of the material discharging shell 5. In the process of the spray gun 9 moving toward the middle, the arrow part of the turning line is drawn. The spray gun 9 is connected to the material storage tank 2 through a hose (not shown in the figure). An electric lead screw 10 is arranged on the rear side of the material discharging shell 5. The electric lead screw 10 is provided with threads symmetrically distributed on the left and right. The electric lead screw 10 is threadedly connected with two transmission sleeves 11 symmetrically distributed on the left and right. A slide groove is arranged on the front side of the transmission sleeve 11. A limited block 12 is slidably connected in the slide groove on the front side of the transmission sleeve 11. The limit block 12 is squeezed and matched with the adjacent sliding frame 8. When the electric lead screw 10 drives the transmission sleeve 11, the limit block 12 is pressed and matched with the adjacent sliding frame 8. When the movable sleeve 11 moves outward, the limit block 12 pushes the adjacent sliding frame 8 on the adjusting two-way telescopic rod 7 to move together. The back sides of the two transmission sleeves 11 are fixedly connected with transmission plates 13. A sliding rod is provided at the front part of the discharge shell 5. The front parts of the two transmission plates 13 are slidably connected with the sliding rod on the discharge shell 5. The transmission plate 13 is limitedly matched with the adjacent sliding frame 8 on the elastic two-way telescopic rod 6. After the transmission sleeve 11 stops moving, the transmission plate 13 limits the distance that the telescopic end of the elastic two-way telescopic rod 6 drives the adjacent sliding frame 8 to move. A limit assembly for driving the movement of two adjacent limit blocks 12 is provided on the discharge shell 5, and an adjustment assembly for driving the rotating shaft 3 to rotate is provided on the frame 1.

[0034] like Figure 5-Figure 7As shown, the limit assembly includes a first electric push rod 21, which is fixed to the upper side surface of the inner rear side of the discharge shell 5, and the telescopic end of the first electric push rod 21 is fixed to the first two-way telescopic frame 22, and the telescopic ends of the first two-way telescopic frame 22 are respectively fixed to the adjacent limit blocks 12. When the arrow part of the U-turn line is marked, the telescopic end of the first electric push rod 21 moves upward, and the telescopic end of the first two-way telescopic frame 22 drives the two limit blocks 12 to move upward, so that the limit block 12 is separated from the adjacent sliding frame 8, so that the telescopic end of the adjusting two-way telescopic rod 7 drives the adjacent sliding frame 8 to move and reset.

[0035] like Figure 8 As shown, the adjustment component includes a motor 31, which is fixedly connected to the lower side of the frame 1, and a transmission ring 32 is splined at the lower end of the rotating shaft 3. The output shaft of the motor 31 is provided with a frustum wheel, and the transmission ring 32 cooperates with the frustum wheel for transmission. When the arc part of the U-turn steering line is marked, the motor 31 drives the unloading shell 5 to rotate through the transmission ring 32, and a spring is arranged between the transmission ring 32 and the rotating shaft 3. A transmission telescopic rod 33 is fixedly connected to the lower side of the frame 1, and the telescopic end of the transmission telescopic rod 33 is extruded and matched with the transmission ring 32. A first elastic telescopic rod 34 is fixedly connected to the right side of the unloading shell 5, and the transmission telescopic rod 33 and the first elastic telescopic rod 34 are both filled with hydraulic oil. A guide block is fixedly connected to the lower side of the fixed part of the electric telescopic frame 4, and an arc-shaped slide groove is arranged on the front part of the upper side of the frame 1. The guide block on the electric telescopic frame 4 slides in the arc-shaped slide groove on the frame 1 The guide block is used to strengthen the support of the frame 1 to the electric telescopic frame 4. The telescopic end of the first elastic telescopic rod 34 is fixedly connected to the guide block. When the electric telescopic frame 4 drives the discharge shell 5 to move outward, the telescopic end of the first elastic telescopic rod 34 is stretched, and the fixed part of the first elastic telescopic rod 34 is connected to the fixed part of the transmission telescopic rod 33, and the diameter of the fixed part of the first elastic telescopic rod 34 is smaller than the diameter of the fixed part of the transmission telescopic rod 33. The diameter difference between the two telescopic rods is used to make the moving distance of the discharge shell 5 and the downward moving side distance of the transmission ring 32 change proportionally. After the telescopic end of the first elastic telescopic rod 34 is stretched, the telescopic end of the transmission telescopic rod 33 pushes the transmission ring 32 to move downward, so that the transmission ratio between the transmission ring 32 and the conical wheel on the motor 31 is reduced. When the transmission ring 32 moves upward, the transmission ratio between the transmission ring 32 and the conical wheel on the motor 31 is increased.

[0036] When the staff uses the device to mark the guide line on the road (taking the turning line as an example), the staff adjusts the direction of the frame 1 (taking Figure 1direction is the reference direction), and moves the frame 1 to the position where marking is required. When the frame 1 moves to the designated position, the staff puts the paint into the storage tank 2 (the storage tank 2 is an existing device, which has the function of heating and mixing the materials). Then the staff starts the electric telescopic frame 4 and adjusts the extension distance of the telescopic end of the electric telescopic frame 4. The telescopic end of the electric telescopic frame 4 drives the unloading shell 5 to move to the left, and the unloading shell 5 drives the parts thereon to move to the left. When the unloading shell 5 moves to the designated position, the staff closes the electric telescopic frame 4, and the unloading shell 5 no longer moves to the left.

[0037] In the process of the above-mentioned discharge shell 5 moving to the left, the discharge shell 5 drives the fixed part of the first elastic telescopic rod 34 to move to the left, the telescopic end of the first elastic telescopic rod 34 extends out and extracts the hydraulic oil in the transmission telescopic rod 33, and the telescopic end of the transmission telescopic rod 33 extends downward and pushes the transmission ring 32 to move downward, so that the transmission ring 32 moves downward and compresses the adjacent spring. After the transmission ring 32 moves, the transmission ratio between the transmission ring 32 and the conical wheel on the motor 31 is reduced, thereby reducing the rotation speed of the shaft 3, avoiding that after the distance between the discharge shell 5 and the frame 1 increases, the rotation radius of the discharge shell 5 increases, and the rotation speed of the shaft 3 remains unchanged, resulting in uneven spraying of the spray gun 9. After the discharge shell 5 stops moving, the transmission ring 32 stops moving downward.

[0038] After the unloading shell 5 stops moving, the staff starts the electric screw 10 and adjusts the distance between the two rear sliding frames 8 according to the width of the road surface so that the ratio between the turning line drawn by the device and the road is appropriate. The electric screw 10 drives the two transmission sleeves 11 to move to the left and right sides respectively through the thread, and the transmission sleeve 11 drives the parts thereon to move to the left. In this process, as the two limit blocks 12 move away from each other, the telescopic end of the first two-way telescopic frame 22 is gradually stretched. As the transmission sleeve 11 on the left moves to the left, when the limit block 12 on the transmission sleeve 11 contacts the adjacent sliding frame 8, the limit block 12 squeezes the adjacent sliding frame 8 to the left, and the sliding frame 8 drives the parts thereon to move to the left and stretch the adjacent telescopic ends on the two-way telescopic rod 7, and the pressure inside the two-way telescopic rod 7 is increased, and the gas inside is passed through the two-way telescopic rod 7. The hose enters the elastic two-way telescopic rod 6, so that the telescopic end of the elastic two-way telescopic rod 6 pushes the two adjacent sliding frames 8 to move left and right. Since the diameter of the fixed part of the elastic two-way telescopic rod 6 is smaller than the diameter of the fixed part of the adjustable two-way telescopic rod 7, the speed of movement of the telescopic end of the elastic two-way telescopic rod 6 is greater than the speed of movement of the telescopic end of the adjustable two-way telescopic rod 7. In the process of extending the telescopic end of the elastic two-way telescopic rod 6, when the sliding frame 8 on it contacts the adjacent transmission plate 13, the sliding frame 8 moves with the adjacent transmission plate 13, and the excess gas between the elastic two-way telescopic rod 6 and the adjustable two-way telescopic rod 7 is compressed. When the distance between the two sliding frames 8 on the rear side is appropriate, the staff turns off the electric screw 10, and the transmission sleeve 11 stops driving the two limit blocks 12 to move, so that the four sliding frames 8 all stop moving.

[0039] During the extension of the telescopic end of the elastic bidirectional telescopic rod 6, since the elastic bidirectional telescopic rod 6 is located on the left side of the left-right symmetry line of the discharge shell 5, when the sliding frame 8 on its left side contacts the adjacent transmission plate 13, the sliding frame 8 on the left side moves to the left together with the adjacent transmission plate 13. At this time, since the movement speed of the left sliding frame 8 decreases, and the rate at which gas enters the fixed part of the elastic bidirectional telescopic rod 6 remains unchanged, the movement of the sliding frame 8 on the right side of the elastic bidirectional telescopic rod 6 increases and quickly approaches the adjacent transmission plate 13. When the sliding frame 8 on the right side contacts the adjacent transmission plate 13, the two sliding frames 8 on the telescopic end of the elastic bidirectional telescopic rod 6 are symmetrical about the symmetry line of the discharge shell 5, so that the spray guns 9 thereon are symmetrically distributed, and the two sliding frames 8 move together with the adjacent transmission plate 13.

[0040] After the adjustment between the two rear sliding frames 8 is completed, the staff starts the spray guns 9 on the two rear sliding frames 8 (if the distance between the two rear sliding frames 8 is greater than half the length of the electric lead screw 10, the staff simultaneously starts the spray guns 9 on the rear side of the unloading shell 5 to avoid the situation where the spray guns 9 on the two rear sliding frames 8 are too far apart, resulting in less paint in the middle of the turning line and inconvenient observation), the two spray guns 9 spray paint downwards, the staff pushes the frame 1 forward, the frame 1 drives the spray guns 9 to move forward to mark the road surface, and when the frame 1 moves forward a specified distance, The staff stops pushing the frame 1 and starts the motor 31. At this time, the spray gun 9 located on the upper rear side of the blanking shell 5 completes the marking of the straight line in the U-turn line. The output shaft of the motor 31 drives the cone wheel thereon to rotate. The cone wheel drives the rotating shaft 3 to rotate through the transmission ring 32. The rotating shaft 3 drives the electric telescopic frame 4 and the parts thereon to rotate, so that the spray gun 9 rotates around the rotating shaft 3, thereby drawing the arc in the U-turn line. When the rotating shaft 3 rotates 180°, the staff turns off the motor 31, and the motor 31 stops driving the rotating shaft 3 to rotate, so that the spray gun 9 stops moving and completes the drawing of the arc part in the U-turn line.

[0041] After completing the marking of the arc part in the U-turn line, the staff pulls the frame 1 backward. When the frame 1 moves a certain distance, the staff starts the first electric push rod 21 and the two spray guns 9 on the front side of the blanking shell 5 to mark the part of the arrow in the U-turn line. The telescopic end of the first electric push rod 21 drives the first two-way telescopic frame 22 to move upward, and the first two-way telescopic frame 22 drives the two limit blocks 12 to move upward. As the limit blocks 12 move upward, when the limit blocks 12 are separated from the adjacent sliding frame 8, the staff closes the first electric push rod 21, and the first two-way telescopic frame 22 and the two limit blocks 12 stop moving. After the two sliding frames 8 on the adjustable two-way telescopic rod 7 stop moving and lose their limit, the gas in the fixed part of the elastic two-way telescopic rod 6 returns to the adjustable two-way telescopic rod 7 under the squeezing of its two telescopic ends, so that the telescopic ends of the adjustable two-way telescopic rod 7 drive the adjacent sliding frames 8 to approach each other, so that the spray guns 9 thereon move backward with the frame 1 and approach each other, so that the spray guns 9 thereon mark the inside of the arrow part in the U-turn turning line, and when the pressure in the elastic two-way telescopic rod 6 is restored, the two sliding frames 8 thereon drive the adjacent spray guns 9 to move at the same speed and approach each other, so that the two spray guns 9 mark the edge position of the arrow.

[0042] In the process of marking the arrow area in the U-turn line, when the distance between the two sliding frames 8 on the rear side of the lower material shell 5 is less than one quarter of the length of the electric lead screw 10, the staff will turn off the spray guns 9 on the two sliding frames 8 and start the spray gun 9 between the two sliding frames 8 on the rear side (if the spray gun 9 has been turned on before, only the spray guns 9 on the two sliding frames 8 will be turned off) to avoid the distance between the two spray guns 9 being too small, resulting in interference in the paths of the paint sprayed, so that the paint sprayed from the two spray guns 9 collides with each other and splashes, affecting the integrity of the marking of the U-turn line. The two sliding frames 8 are close to each other. When the left sliding frame 8 contacts the fixed part of the elastic two-way telescopic rod 6, the staff turns off the spray gun 9 on it. At this time, the telescopic end on the right side of the elastic two-way telescopic rod 6 continues to drive the spray gun 9 on it to move, and draws a line on the head of the arrow to avoid the above-mentioned mutual interference between the two spray guns 9. When the sliding frame 8 on the right side of the elastic two-way telescopic rod 6 is reset, the two adjacent spray guns 9 of the two-way telescopic rod 7 are adjusted to complete the reset. The staff turns off all the spray guns 9 on the blanking shell 5 and the spray gun 9 on the right side of the elastic two-way telescopic rod 6 and completes the marking of the turning line.

[0043] After the marking of the turning line is completed as mentioned above, the staff starts the electric screw 10, and the electric screw 10 rotates in the opposite direction, so that the two transmission sleeves 11 drive the parts thereon to approach each other and reset. In this process, the two limit blocks 12 approach each other to make the telescopic end of the first two-way telescopic frame 22 retract and reset. When the transmission sleeve 11 completes the reset, the staff turns off the electric screw 10 and starts the first electric push rod 21. The telescopic end of the first electric push rod 21 drives the first two-way telescopic frame 22 to move downward, and the telescopic end of the first two-way telescopic frame 22 drives the two limit blocks 12 to move downward and reset. When the limit block 12 contacts the lower side of the slide groove on the adjacent transmission sleeve 11, it no longer moves and completes the reset. The staff After the first electric push rod 21 is turned off, the staff starts the motor 31 and the electric telescopic frame 4 backward, so that the rotating shaft 3 drives the unloading shell 5 and the parts thereon to rotate in the opposite direction and reset. After the rotating shaft 3 is reset, the staff turns off the motor 31, and then the telescopic end of the electric telescopic frame 4 drives the unloading shell 5 to move rightward and reset, and retracts and resets the telescopic ends of the transmission telescopic rod 33 and the first elastic telescopic rod 34. The transmission ring 32 moves upward under the push of the adjacent spring and restores the transmission ratio between it and the conical wheel on the motor 31. After the unloading shell 5 is reset, the staff turns off the electric telescopic frame 4 to complete the reset of the device. After that, the staff repeats the above process for marking other positions where the device needs to be marked.

[0044] When workers are marking on the road with a spray gun, they need to keep a certain distance between the spray gun and the road surface to avoid the spray gun being too close to the road surface, which will cause a strong reaction force and splash when the high-pressure paint hits the road surface. However, when encountering strong winds, this method will move the trajectory of the paint sprayed by the spray gun, causing the landing point of the paint to change, affecting the accuracy of the marking device.

[0045] Embodiment 2: Based on embodiment 1, Figure 2 and Fig. 9 As shown, it also includes a protection mechanism, which is arranged on the discharge shell 5. The protection mechanism is used to reduce the interference of natural wind on the spray gun 9. The protection mechanism includes two second electric push rods 41 symmetrically distributed on the left and right. The two second electric push rods 41 are fixed to the middle of the upper side of the discharge shell 5. The telescopic ends of the second electric push rods 41 are fixed to the extrusion rods 42. The discharge shell 5 is slidably connected with two protective plates 43 symmetrically distributed on the left and right (the protective plates 43 are initially in contact with the road surface). The protective plates 43 are used to block the wind in the left and right directions of the device to prevent the wind from blowing the paint sprayed from the spray gun 9, causing the trajectory of the paint movement to be disturbed. The protective plates 43 and the discharge shell 5 are connected. A spring is provided, and the spring is used to make the protective plate 43 fit with the road surface when not subjected to external force. Conical blocks 44 are fixedly connected to the upper parts of the opposite sides of the two protective plates 43, and the opposite sides of the two conical blocks 44 are provided with inclined surfaces facing downward. The side of the extrusion rod 42 close to the adjacent conical block 44 is provided with an inclined surface facing upward. The inclined surface on the conical block 44 is extruded and matched with the inclined surface on the adjacent extrusion rod 42. When the extrusion rod 42 moves outward, the extrusion rod 42 drives the adjacent protective plate 43 to move upward through the adjacent conical block 44. The spray gun 9 is ball-connected with the adjacent sliding frame 8. A detection mechanism is provided on the discharge shell 5, and the detection mechanism is used to detect the external wind speed.

[0046] like Figure 3 and Figure 9-13As shown, the detection mechanism includes a detection rod 51, which is rotatably connected to the blanking shell 5, and the two extrusion rods 42 are both extruded and matched with the detection rod 51, and in the initial state, the two extrusion rods 42 jointly fix the detection rod 51 so that the detection rod 51 cannot rotate, and a wind force detector is arranged on the top of the detection rod 51, which is used to detect the external wind speed and drive the detection rod 51 to rotate, and the upper part of the detection rod 51 located outside the blanking shell 5 is fixedly connected with a symmetrically distributed second elastic telescopic rod 52, and the telescopic end of the second elastic telescopic rod 52 is provided with a weight block. When the detection rod 51 rotates, the weight block drives the telescopic end of the adjacent second elastic telescopic rod 52 to extend, and the lower part of the detection rod 51 is splined with a lifting ring 53, and the telescopic parts of the two second elastic telescopic rods 52 are There are soft ropes connected to the lifting ring 53, and the lower part of the lifting ring 53 is rotatably connected to the lifting sleeve 54. The lower side of the lifting sleeve 54 is fixedly connected to an adjusting plate 55. A spring is arranged between the adjusting plate 55 and the detection rod 51, and the adjusting plate 55 is slidably connected to the blanking shell 5. When the detection rod 51 rotates, the telescopic part of the second elastic telescopic rod 52 drives the lifting ring 53 to move upward through the soft rope, so that the adjusting plate 55 moves upward synchronously with the lifting ring 53, and the greater the external wind speed, the greater the distance the adjusting plate 55 moves upward. The lower side of the adjusting plate 55 is slidably connected to five L-shaped plates 56 distributed symmetrically on the left and right, among which there are two L-shaped plates 56 on the front part of the lower side of the adjusting plate 55, and an extrusion component for changing the angle of adjacent spray guns 9 is arranged on the sliding frame 8.

[0047] like Figure 3-Figure 5 and Figure 9-13 As shown, the extrusion assembly includes an adjustment sleeve 61, which is rotatably connected to the outer side of the adjacent sliding frame 8, and the outer side of the adjustment sleeve 61 is slidably connected to the extrusion ring 62, and the outer side of the extrusion ring 62 is provided with a slide groove, and the L-shaped plate 56 is located in the slide groove on the adjacent extrusion ring 62 and slides, and the lower side of the extrusion ring 62 is fixed with an L-shaped rod 63, and the lower part of the adjustment sleeve 61 is close to the adjacent L-shaped rod 63. The side of the adjacent L-shaped rod 63 is fixed with a transmission rod 64, and the transmission rod 64 is composed of a round rod and a trapezoidal block, and the inclined surface of the trapezoidal block faces the lower side. A spring is provided between the trapezoidal block on the transmission rod 64 and the adjacent adjustment sleeve 61, and the spray gun 9 is extruded and matched with the round rod on the adjacent transmission rod 64, and the L-shaped rod 63 is fixedly connected to the lower side of the extrusion ring 62. 3 is pressed and matched with the inclined surface on the trapezoidal block of the adjacent transmission rod 64, and the moving distance of the L-shaped rod 63 is less than the height of the trapezoidal block on the transmission rod 64. When the L-shaped rod 63 moves upward, the L-shaped rod 63 is prevented from being separated from the adjacent transmission rod 64. The transmission rod 64 is reset and extended under the action of the adjacent spring, resulting in the L-shaped rod 63 being unable to move downward and reset. When the L-shaped rod 63 moves upward, the L-shaped rod 63 squeezes the inclined surface of the adjacent transmission rod 64, so that the transmission rod 64 pushes the adjacent spray gun 9 to deflect, so that the spray gun 9 faces the incoming wind direction, reducing the deflection degree of the paint sprayed by the spray gun 9. A rotating assembly for driving all the adjustment sleeves 61 to rotate is provided on the detection rod 51.

[0048] like Figure 10-13 As shown, the rotating assembly includes a guide rod 71, which is slidably connected to the detection rod 51, the lower part of the guide rod 71 passes through the middle part of the adjustment plate 55, and a wind vane is arranged on the top of the guide rod 71, which is used to detect the direction of wind, and a gear is arranged at the lower end of the guide rod 71, and a guide frame 72 is slidably connected to the lower side of the discharge shell 5, and a slide groove is arranged on the lower side of the discharge shell 5, and the guide frame 72 slides in the adjacent slide groove on the discharge shell 5, and a spring is arranged between the guide frame 72 and the discharge shell 5, and a first rack 73 is fixedly connected to the lower side of the guide frame 72, and the first rack 73 is meshed with the gear on the guide rod 71 for transmission, and the first rack 73 is fixedly connected to two second bidirectional telescopic frames 74 symmetrically distributed front and back. The telescopic ends of the two second two-way telescopic frames 74 are fixedly connected with second racks 75, and the rear side surface of the fixed part of the rear second two-way telescopic frame 74 is also fixedly connected with a second rack 75. An outer toothed ring is provided on the upper side of the adjusting sleeve 61, and the second rack 75 is meshed with the adjacent outer toothed ring for transmission. When the guide rod 71 rotates, the guide rod 71 drives the first rack 73 to move, so that the second rack 75 drives the adjacent adjusting sleeve 61 to rotate through the adjacent outer toothed ring, so that the adjusting sleeve 61 drives the adjacent transmission rod 64 to rotate, so that the transmission rod 64 is located on the leeward side of the adjacent spray gun 9, so that when the L-shaped rod 63 squeezes the adjacent transmission rod 64, the transmission rod 64 pushes the adjacent spray gun 9 to rotate in the incoming wind direction.

[0049] When marking the U-turn line as mentioned above, if there is no strong wind, the staff starts the two second electric push rods 41, and the second electric push rod 41 on the left side drives the adjacent squeezing rod 42 to move leftward, so that the squeezing rod 42 squeezes the adjacent conical block 44 upward, and the conical block 44 drives the adjacent protective plate 43 (initially in contact with the ground) to move upward, and the protective plate 43 moves upward to separate from the ground and compresses the adjacent spring, and then the staff repeats the above process to adjust the distance between the adjacent sliding frames 8. During this process, the sliding frame 8 drives the adjustment sleeve 61 thereon to move, and the adjustment sleeve 61 drives the squeezing ring 62 and other parts thereon to move and squeeze the adjacent second rack 75 through the outer gear ring thereon, so that the adjacent second rack 75 moves therewith and stretches the telescopic end of the adjacent second two-way telescopic frame 74, and the squeezing ring 62 drives the adjacent L-shaped plate 56 to move synchronously. When the sliding frame 8 stops moving, the adjustment sleeve 61 and its adjacent parts no longer move, and then the staff repeats the above process to mark the U-turn line.

[0050] If strong winds are encountered during the marking process (taking the right wind as an example, the wind direction at this time is only left and right relative to the moving direction of the frame 1. Since the wind on the front and rear sides of the moving direction of the frame 1 affects the paint sprayed by the spray gun 9 as a front-to-rear offset, the effect on the left and right directions is not significant, so no detailed description is given), when marking the straight area of ​​the U-turn line, the staff does not start the second electric push rod 41. At this time, the protective plate 43 blocks the left and right sides of the discharge shell 5 to prevent the wind on the left and right sides of the frame 1 from blowing the paint sprayed by the spray gun 9, causing the drawn U-turn line to be misaligned, affecting the normal use of the U-turn line.

[0051] During this process, the guide rod 71 rotates counterclockwise under the drive of the wind vane on it ( Figure 1 When the wind vane on the guide rod 71 points to the direction of the incoming wind, the guide rod 71 stops rotating. During this process, the guide rod 71 drives the gear thereon to rotate, and the gear drives the first rack 73 to move forward. The first rack 73 drives the guide frame 72 to move forward and compresses its adjacent spring. At the same time, the first rack 73 drives the two second two-way telescopic frames 74 to move forward. The two second two-way telescopic frames 74 respectively drive the second racks 75 thereon to move forward, so that the second rack 75 drives the adjacent adjusting sleeve 61 to rotate through the outer gear ring on the adjusting sleeve 61, and the adjusting sleeve 61 drives the parts thereon to rotate. When the guide rod 71 stops rotating, the adjusting sleeve 61 and the adjacent parts thereon no longer rotate. At this time, the L-shaped rod 63 is located in the leeward position of the adjacent adjusting sleeve 61, so that when the adjacent transmission rod 64 is extended, the transmission rod 64 pushes the adjacent spray gun 9 to deviate in the direction of the incoming wind, thereby reducing the influence of the wind on the position where the paint is sprayed.

[0052] After the marking of the straight area of ​​the U-turn line is completed, the staff repeats the above process to start the second electric push rod 41, so that the protective plate 43 repeats the above process to move upward and separate from the ground, so as to avoid the protective plate 43 from contacting the paint of the U-turn line that has been marked during the rotation process, thereby damaging the U-turn line at that location and affecting the normal use of the U-turn line. After the squeezing rod 42 on the left side moves to the left, the squeezing rod 42 is separated from the detection rod 51 and the limit on it is released. The detection rod 51 rotates under the action of the wind force detector thereon, and the detection rod 51 drives the lifting ring 53 and the two second elastic telescopic rods 52 thereon to rotate. The telescopic end of the second elastic telescopic rod 52 extends out under the action of its weight, and the telescopic end of the second elastic telescopic rod 52 moves and stretches the adjacent soft rope on the lifting ring 53, so that the lifting ring 53 drives the lifting The lowering sleeve 54 moves upward, and the lifting sleeve 54 drives the adjustment plate 55 to move upward and compress the adjacent spring. The adjustment plate 55 drives the L-shaped plate 56 thereon to move upward, so that the L-shaped plate 56 drives the adjacent L-shaped rod 63 to move upward through the adjacent extrusion ring 62. When the L-shaped rod 63 contacts the inclined surface of the trapezoidal block on the adjacent transmission rod 64, the L-shaped rod 63 squeezes the adjacent transmission rod 64 to the right, and the transmission rod 64 squeezes the adjacent spray gun 9 to the right, so that the spray gun 9 is offset in the direction of the incoming wind, thereby reducing the influence of the wind on the position of the paint sprayed therefrom, and avoiding the wind from deviating the paint sprayed from the spray gun 9. When spraying the arc part of the U-turn line, as the discharge shell 5 rotates, the direction of the wind vane on the guide rod 71 changes with the rotation of the discharge shell 5, so that it is always facing the direction of the incoming wind, so that the adjacent spray gun 9 is always offset in the direction of the incoming wind.

[0053] After the partial spraying of the turning line arc is completed, the staff starts the second electric push rod 41 again, so that the telescopic end of the second electric push rod 41 drives the adjacent extrusion rod 42 to move and reset and no longer squeezes the adjacent protective plate 43. The protective plate 43 moves downward and resets under the drive of the adjacent spring. When the protective plate 43 contacts the ground again, it stops moving and completes the reset. At this time, the extrusion rod 42 contacts the detection rod 51 and completes the limiting of it again. The detection rod 51 no longer drives the parts thereon to rotate. The telescopic end of the second elastic telescopic rod 52 drives the adjacent weight block to move and reduce the pulling force of the soft rope on the lifting ring 53. The lifting sleeve 54 drives the parts thereon to move downward and reset under the push of the adjacent spring, so that the L-shaped plate 56 drives the adjacent extrusion ring 62 to move downward to reduce the extrusion force on the adjacent transmission rod 64, so that the transmission rod 64 is separated from the adjacent spray gun 9 and resets.

[0054] After the turning line of the U-turn is marked, the staff repeats the above-mentioned starting motor 31 and the electric telescopic frame 4, so that the rotating shaft 3 drives the unloading shell 5 and the parts thereon to rotate in the opposite direction and reset. After the rotating shaft 3 is reset, the staff turns off the motor 31, and starts the telescopic end of the electric telescopic frame 4 to drive the unloading shell 5 to drive the parts thereon to move and reset. After the unloading shell 5 is reset, the staff turns off the electric telescopic frame 4 and completes the reset of the device. Thereafter, the staff reversely rotates the guide rod 71, and the gear on the guide rod 71 drives the guide frame 72 and the parts thereon to move backward and reset, so that the second rack 75 drives the outer gear ring on the adjacent adjusting sleeve 61 to rotate, so that the parts on the adjusting sleeve 61 rotate and reset. Thereafter, the staff repeats the above process to mark other positions.

[0055] While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.
