[0033] Example

[0034] Please see Figure 1-5As shown, this utility model provides a two-axis contactless car wash machine with contour cleaning function: it includes a fixed frame 110 and a detection platform 120. The fixed frame 110 is fixedly installed on the detection platform 120 by expansion bolts. The top of the fixed frame 110 is equipped with a gantry assembly 130 for contour cleaning of vehicles. The gantry assembly 130 includes a gantry walking track 131, a gantry outer frame 132, an ultrasonic distance sensor 134, a central rotating shaft 135, a rotating jet swing arm 137, and a rotating angle positioning encoder 1310. The gantry walking track 131 is arranged according to... The vehicle is fixedly installed on both sides of the top of the fixed frame 110 in the parking direction. The outer frame 132 of the astronomical device has driving wheels 133 mounted on both sides via drive shafts 1331, and the wheels 133 allow the astronomical device to move along the track 131. An ultrasonic distance sensor 134 for irradiating the detection platform 120 is installed at the bottom of the outer frame 132. A central rotating shaft 135 is installed at the center of the outer frame 132, and is connected to a first reduction motor 136, which controls the rotation angle positioning encoder. 1310 is installed on the outer frame 132 of the astronaut and connected to the central rotating shaft 135. The rotation angle positioning encoder 1310 is used to detect the rotation angle of the rotating jet swing arm 137 and realize the fixed angle rotation of the rotating jet swing arm 137. The rotating jet swing arm 137 is connected to the central rotating shaft 135 and installed below the outer frame 132 of the astronaut. The rotating jet swing arm 137 is equipped with a rotating jet pipe 138 for washing vehicles. The rotating jet swing arm 137 is controlled by a drive reduction motor 139 connected to the rotating jet pipe. The system operates by installing a high-pressure plunger pump 173 for providing high-pressure cleaning water, a car wash liquid tank 174 for providing car wash liquid, and an electrical control cabinet 175 on one side of the fixed frame 110. The system uses an ultrasonic distance sensor 134 to detect the distance between the vehicle and the ground of the detection platform 120 and to determine the vehicle's parking status. Then, an ultrasonic detector detects the vehicle's posture and contour. Finally, a rotating jet swing arm 137 is used for contour cleaning. The system can monitor different vehicle contours in real time and maintain the appropriate distance between the rotating jet swing arm 137 and the vehicle body to achieve the best car wash effect.

[0035] Furthermore, the walking wheels 133 are set on both sides of the outer frame 132 of the Tianji through the transmission shaft 1331. The transmission shaft 1331 is connected to the Tianji walking drive reduction motor 1332 and is controlled by the Tianji walking drive reduction motor 1332. Walking anti-tipping wheels 150 are installed on both sides of the outer frame 132 of the Tianji to ensure the safety of the Tianji component 130 during car washing.

[0036] Furthermore, the ultrasonic distance sensor 134 pre-detects the distance Y to the detection platform 120 in the absence of a vehicle and in standby mode, and controls the PLC to calibrate within the range of Y±20cm as the absence of a vehicle. When a vehicle enters the detection platform 120, the parking position photoelectric detector 171 and the parking overshoot photoelectric detector 172 confirm that the front edge of the vehicle has reached the correct position. The ultrasonic distance sensor 134 then performs a secondary confirmation of the vehicle's parking status using the value Y±20cm. Then, the gantry assembly 130 starts moving forward, and the rotating jet swing arm 137 cleans the side of the vehicle. The ultrasonic distance sensor 134 detects in real time and compares the detected value with Y±20cm. When the values ​​are met, the PLC determines that the gantry assembly 130 has moved to the rear of the vehicle, and the gantry assembly 130 stops running. The rotating jet swing arm 137 rotates and cleans the rear of the vehicle. Finally, when the gantry assembly 130 returns, the ultrasonic distance sensor 134 does not need to detect, and the gantry assembly 130 returns to the starting point.

[0037] Furthermore, two ultrasonic detectors for detecting distances are installed on both sides of the fixed frame 110. A parking position photoelectric detector 171 and a parking overshoot photoelectric detector 172 are installed near the front of the fixed frame 110 to detect the vehicle's position. After the vehicle enters the detection platform 120, the parking position photoelectric detector 171 and the parking overshoot photoelectric detector 172 determine whether the front edge of the vehicle has reached the correct position, and the rear of the vehicle is detected by the ultrasonic distance sensor 134. Then, the distances from the two sides of the fixed frame 110 to the vehicle are detected by the four ultrasonic detectors and recorded as A, B, C, and D respectively. The distances from the center of the detection platform 120 to the two ends of the fixed frame 110 are subtracted from the distances from the two sides of the fixed frame 110 to the vehicle to obtain the distances from the center of the detection platform 120 to the two sides of the vehicle, namely LA, LB, LC, and LD respectively. The boundary line of one side of the vehicle is fitted by LA and LB, and the boundary line of the other side of the vehicle is fitted by LC and LD.

[0038] Furthermore, the rotating jet swing arm 137 includes a horizontal jet swing arm tube 1371 and a vertical jet swing arm tube 1372. The horizontal jet swing arm tube 1371 is connected to the central rotating shaft 135, and the vertical jet swing arm tube 1372 is movably connected to the horizontal jet swing arm tube 1371. The outer frame 132 is equipped with a high-pressure water pipe 141 and a car wash liquid pipe 142 that connect to the rotating jet swing arm 137. The high-pressure water pipe 141 is connected to a fan 1311 that provides pressure, and the fan 1311 is installed inside the outer frame 132.

[0039] Furthermore, the central rotating shaft 135 is driven by the first reduction motor 136 to achieve rotation. Simultaneously, a rotation angle positioning encoder 1310 is installed on the central rotating shaft 135 to detect the rotation angle, thus achieving a fixed-angle rotation of the jet swing arm 137. When the axis of the jet swing arm horizontal tube 1371 is perpendicular to the central rotating shaft 135, the distance from the jet swing arm vertical tube 1372 to the central rotating shaft 135 is denoted as W. When the jet swing arm horizontal tube 1371 rotates by an angle α, the distance from the jet swing arm vertical tube 1372 to the central rotating shaft 135 is denoted as W. The distance between pipe 1372 and the central rotation axis 135 is denoted as W1 = W × cosα. The PLC sets W1 = L-A + 25, W1 = L-B + 25, W1 = L-C + 25, and W1 = L-D + 25, so that the vertical pipe of the jet swing arm 1372 is 25cm away from the vehicle for cleaning. This ensures that the high-pressure water has a good rinsing effect, and also ensures that the vertical pipe of the jet swing arm 1372 is at a sufficient safe distance from the car, while avoiding scratching the car's rearview mirror.

[0040] The working principle of this utility model is as follows:

[0041] In this embodiment, a two-axis contactless car wash machine with contour cleaning function is used. When a vehicle enters the detection platform 120, the front edge of the vehicle is determined to be in the correct position by the parking position photoelectric detector 171 and the parking overshoot photoelectric detector 172. The distance between the vehicle and the detection platform 120 is detected by the ultrasonic distance sensor 134 and compared with Y±20cm to confirm the rear position of the vehicle. Before the operation of the oscillator component 130, the distances from the two sides of the fixed frame 110 to the vehicle are detected by the four ultrasonic detectors and recorded as A, B, C, and D respectively. The distances from the center of the detection platform 120 to the two ends of the fixed frame 110 are subtracted from the distances from the two sides of the fixed frame 110 to the vehicle to obtain the distances from the center of the detection platform 120 to the two sides of the vehicle, namely LA, LB, LC, and LD respectively. The boundary line of one side of the vehicle is fitted by LA and LB, and the boundary line of the vehicle is fitted by LC and LD. On the other side of the boundary line, the vehicle contouring is now complete. Then, the Tianji component 130 moves forward, the high-pressure plunger pump 173 provides high-pressure cleaning water to the rotating jet swing arm 137, and the car wash liquid tank 174 provides car wash liquid to the rotating jet swing arm 137. Following the contouring path, the horizontal and vertical jet swing arm pipes 1371 and 1372 clean the side of the vehicle. While cleaning, the horizontal and vertical jet swing arm pipes 1371 and 1372 are kept 25cm away from the vehicle body. The ultrasonic distance sensor 134 monitors in real time. When the PLC determines that the Tianji component 130 has reached the rear of the vehicle, the Tianji component 130 stops running. The horizontal and vertical jet swing arm pipes 1371 and 1372 rotate and clean the rear of the vehicle, again keeping the vertical jet swing arm pipe 1372 25cm away from the rear of the vehicle. After cleaning, the Tianji component 130 returns to the starting point.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
