Description

Technical Field

[0001] The present invention relates to the technical field of car washing, and particularly to an all-round foam spraying gantry for an automatic car washer. Background Art

[0002] With the rapid development of the economy, the usage of cars is increasing. Especially with the popularization of private cars, the car ownership has increased, driving the car washing demand to grow day by day. The traditional car washing method is to manually hold a high-pressure water gun to wash the vehicle, but this method has a high labor cost and low car washing efficiency. Therefore, an automated gantry car washing device has emerged, which uses a rotating brush body and water flow to wash the vehicle. However, the existing gantry car washing frame can only achieve washing on both sides or both sides and the top, and it is difficult to achieve all-round washing of the four sides and the top of the vehicle at one time, reducing the washing effect. Moreover, during the washing process, the rotating brush body will splash water stains and other stains around, affecting the surrounding personnel and reducing the car washing experience. At the same time, it is not convenient for the subsequent cleaning and tidying of the car washing environment.

[0003] The defects of the existing gantry car washing frame are as follows: 1. In the patent document CN108608997B, it mainly improves the washing effect through the cooperation of roller brushes and high-pressure spray rods, without considering how to achieve all-round washing of both sides, front and back, and the top of the vehicle, and how to avoid the splashing of foam, water stains and other substances when the brush body rotates; 2. In the patent document CN113928279B, it mainly considers how to wash the top and both sides of the bus, without considering how to avoid water stains dripping on personnel when transferring vehicles when there are many vehicles to be washed; 3. In the patent document CN105363719A, it mainly solves the problem of how to achieve automatic car washing, without considering how to detect whether the vehicle is placed correctly and whether the doors and windows are closed correctly.

The present invention is equipped with a cleaning and protection component, and uses two vertically rotating brush bodies that can be adjusted in position and a horizontally arranged rotating brush body to achieve comprehensive cleaning of the four sides and the top of the vehicle, which is beneficial to improving the vehicle cleaning effect. By setting an outer frame part, the rotating brush body is blocked from the outside, so that substances such as foam, water droplets, and stains thrown out by the rotating brush body are intercepted by the outer frame body, preventing the foam, water droplets, stains, etc. from being thrown around when the rotating brush body rotates, avoiding affecting nearby personnel, and at the same time facilitating the subsequent cleaning of the environment where the car wash gantry is located.

[0016] 2. The present invention is equipped with a hollow arc plate and an inclined airbag. When the spraying gantry finishes washing a car, the servo motor three starts, drives the gear three to rotate through the mounting rod, and then drives the hollow arc plate to rotate through the arc-shaped rack. The hollow arc plate rotates clockwise to the outside of the front frame and the moving gantry, and rotates to a state where the arc-shaped opening faces upward. The air inflation pump is used to inflate the hollow arc plate, so that the inclined airbag is propped up to an inclined state. By setting the hollow arc plate and the inclined airbag, the foam nozzles and liquid nozzles installed on the top wall of the moving gantry and the inclined side top wall are blocked from below, preventing foam and water droplets from dripping onto the driver during the process of the driver of the first car driving out the vehicle and the driver of the next vehicle to be washed parking the vehicle, thereby avoiding reducing the use experience of the spraying gantry.

[0017] 3. The present invention is equipped with a telescopic rod, a support rod, and a hollow ring. After the hollow arc plate and the inclined airbag are used, by alternately driving the telescopic rod to extend and contract, the telescopic rod drives the support rod to move left and right alternately, and then drives the hollow ring to move left and right alternately. The hollow ring drives the inclined airbag to swing left and right, which is convenient for accelerating the dropping of water droplets, preventing foam or water droplets from remaining outside when the inclined airbag contracts, thereby preventing residual water droplets from dripping, and preventing water droplets from being carried into the front frame, playing a certain protective role for the servo motor three.

[0018] 4. The present invention is equipped with a first detection unit and a second detection unit, which detect whether the vehicle is in the center position and whether the vehicle body is in a straight state during the process of the vehicle driving under the outer frame, and prompt the driver to adjust the vehicle position and the vehicle body state in time during driving, which is beneficial to saving adjustment time and improving the car wash efficiency. The third detection unit and the fourth detection unit detect whether the vehicle reaches the designated position and prompt the personnel to perform actions such as parking, getting off, checking and closing the doors and windows, and leaving, ensuring the smooth progress of the car wash process.

[0024] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , an embodiment provided by the present invention: an omnidirectional foam spraying gantry for an automatic car wash machine, including an outer frame 1 and a moving gantry 2. The outer frame 1 includes a top frame and four sets of legs at the bottom of the top frame, and the four sets of legs are respectively located at the four corners of the top frame. The inner wall of the top frame is connected through the moving gantry 2, and the top frame provides support for the moving gantry 2. Two sets of fixed seats 3 are respectively installed on the front and back of the moving gantry 2. A servo motor 1 4 is installed on the top of the right set of fixed seats 3. The servo motor 1 4 is electrically connected to the first detection unit 36. The output end of the servo motor 1 4 is connected to a lead screw 1 5. A limiting rod 19 is installed on the outer wall of the two sets of fixed seats 3 close to each other, and the limiting rod 19 is located below the lead screw 1 5. A moving box 6 is sleeved on the outer walls of the lead screw 1 5 and the limiting rod 19. A cleaning and protection component 15 is arranged in the moving box 6. The cleaning and protection component 15 is used to clean the four sides of the car; The cleaning and protection component 15 includes a fixed rod 7 installed on the top wall of the moving box 6, and the bottom end of the fixed rod 7 penetrates the bottom of the moving box 6 and extends below the moving box 6. An outer frame part 8 and a neck part 9 are sleeved on the outer wall of the fixed rod 7. The bottom end of the neck part 9 is connected to the top of the outer frame part 8. The outer frame part 8 is a hollow columnar structure with an opening on one side, and the neck part 9 is located below the moving box 6. A first gear 10 is fixedly sleeved on the outer wall of the neck part 9. A first servo motor 4 is installed inside the moving box 6, and the moving box 6 provides protection for the first servo motor 4. A second gear 12 is sleeved on the outer wall of the output end of the first servo motor 4. The second gear 12 is located below the moving box 6, and the second gear 12 meshes with the first gear 10. The bottom end of the fixed rod 7 is installed with a motor box 13, and the motor box 13 is located inside the outer frame part 8. A driving motor 11 is installed inside the motor box 13, and the output end of the driving motor 11 is connected with a rotating brush body 14. The rotating brush body 14 is located inside the outer frame part 8; A vertical seat 16 is fixedly arranged on the top of the moving gantry 2. A driving unit 17 is installed on the top wall of the vertical seat 16. The driving unit 17 includes a driving box and a drag chain. One end of the drag chain is connected to the driving box, and the other end of the drag chain is connected with a mounting bracket 18. The driving unit 17 is used to drive the mounting bracket 18 to move up and down. The mounting bracket 18 is located behind the moving gantry 2, and the inner wall of the mounting bracket 18 is connected with a cleaning and protection component 15. The cleaning and protection component 15 is used to clean the top of the vehicle, and the cleaning and protection component 15 for cleaning the top of the vehicle is located between two groups of cleaning and protection components 15 for cleaning the surrounding of the vehicle.

[0025] Further, the first detection unit 36 detects the distances from both sides to the outer walls of the vehicle to be cleaned respectively, so as to obtain the vehicle body width data. For example, when the distance data obtained by the two groups of the first detection units 36 are L1 and L2 respectively, the vehicle body width data is obtained by subtracting L1 and L2 from the known distance between the two groups of the first detection units 36. According to the obtained data, the first servo motor 4 is started, and the first servo motor 4 drives the first lead screw 5 to rotate, so that the first lead screw 5 drives the moving box 6 and the cleaning and protection components 15 on both sides to move, making the distance between the two vertically arranged protection and cleaning components greater than the vehicle body width, and further making the two protection and cleaning components located on both sides of the vehicle body. After the vehicle is parked straight in the designated car wash area, the vehicle is sprayed with liquid by the liquid spray head 21, and then foam is sprayed on the vehicle by the foam head 20. At this time, the opening side of the outer frame part 8 faces away from the vehicle body. After the foam spraying is completed, the second servo motor is started to drive the second gear 12 to rotate. The second gear 12 drives the first gear 10 to rotate, and then drives the neck 9 and the outer frame part 8 to rotate, making the opening side of the outer frame part 8 face the vehicle body direction. Then, the first servo motor 4 is started to drive the cleaning and protection components 15 to move towards each other, making the rotary brush body 14 contact with the outer wall of the vehicle body. The motor box 13 drives the rotary brush body 14 to rotate, and the vehicle is effectively cleaned by using the foam sprayed on the outer wall of the vehicle body. By arranging the outer frame part 8, the rotary brush body 14 is shielded from the outside, so that substances such as foam, water droplets, and stains thrown out by the rotary brush body 14 are intercepted by the outer frame body, preventing the rotary brush body 14 from throwing foam, water droplets, stains and other substances around when rotating, avoiding affecting the nearby personnel, and at the same time facilitating the subsequent cleaning of the environment where the car wash gantry is located; The four sides of the vehicle are cleaned by two sets of vertically arranged cleaning and protection components 15. When starting, both sets of cleaning and protection components 15 are used to clean the outer walls on the left and right sides of the vehicle. When the moving gantry 2 moves to the front side of the vehicle, that is, the position far from the first detection unit 36, a set of servo motor 1 4 in front of the moving gantry 2 is started to drive the lead screw 1 5 to move, and then a set of cleaning and protection components 15 in front is moved to the front of the vehicle. By adjusting the opening direction of the outer frame part 8 through the servo motor 2, the opening faces the side of the vehicle head. Then, the front side of the vehicle is cleaned by the rotating brush body 14, and the cleaning and protection components 15 are driven to move left and right by the lead screw 1 5 to achieve the complete cleaning of the front of the vehicle. Similarly, when the moving gantry 2 moves to the rear of the vehicle, that is, the position close to the first detection unit 36, a set of cleaning and protection components 15 behind the moving gantry 2 is used to clean the rear of the vehicle. The driving unit 17 drives the mounting frame 18 to move downward, and then drives a set of horizontally arranged cleaning and protection components 15 inside the mounting frame 18 to move downward, and rotates the opening side of the outer frame part 8 in the cleaning and protection components 15 downward. The top of the vehicle is cleaned by the rotating brush body 14 inside the outer frame part 8. By setting two sets of vertically arranged and one set of horizontally arranged cleaning components, the omnidirectional cleaning of the vehicle is realized, and different models of vehicles can be washed, improving the application range of the spraying gantry.

[0026] Please refer to Figure 6 , Figure 7 and Figure 8 As shown in FIGS.

[0027] Further, when the spray gantry finishes washing a car, the third servo motor 23 starts, drives the third gear 24 to rotate through the mounting rod, and then drives the hollow arc plate 28 to rotate through the arc-shaped rack 25. The hollow arc plate 28 rotates clockwise to the outside of the front frame 22 and the moving gantry 2 and rotates to a state where the arc-shaped opening faces upward. The inflation pump 29 inflates the hollow arc plate 28 to make the inclined airbag 31 support into an inclined state. By setting the hollow arc plate 28 and the inclined airbag 31, the foam nozzles and liquid nozzles 21 installed on the top wall of the moving gantry 2 and the inclined side top wall are shielded from below, avoiding foam and water droplets from dripping onto the driver during the process of the driver of the first car driving out the vehicle and the driver of the next vehicle to be washed parking the vehicle, thus avoiding reducing the use experience of the spray gantry; When the moving gantry 2 needs to be used for spraying again, the air extraction pump 30 discharges the gas inside the hollow arc plate 28 and the inclined airbag 31, and keeps the inside of the hollow arc plate in a slightly negative pressure state, thereby facilitating the contraction of the inclined airbag 31 and reducing the space occupied by the inclined airbag 31. The third servo motor 23 drives the third gear 24 to rotate in the reverse direction, and retracts the hollow arc plate 28 into the front frame 22 and the moving gantry 2.

[0028] Please refer to Figure 8 As shown in, an embodiment provided by the present invention: an all-round foam spray gantry for an automatic car washer, including two groups of first telescopic rods 32 symmetrically installed on the outer wall of the hollow arc plate 28, and the first telescopic rods 32 are located between the two groups of inclined airbags 31. The output end of the first telescopic rod 32 is connected to a support rod 33. One end of the support rod 33 close to the inclined airbag 31 is connected to a hollow frame 34, and the hollow frame 34 is sleeved on the outer wall of the inclined airbag 31. The first telescopic rod 32 and the support rod 33 penetrate through the outer wall of the arc-shaped rack 25.

[0029] Further, when the hollow arc plate 28 and the inclined airbag 31 are no longer in use, by alternately driving the telescopic rod to extend and retract, the telescopic rod drives the support rod 33 to move left and right alternately, and then drives the hollow ring to move left and right alternately. The hollow ring drives the inclined airbag 31 to swing left and right, facilitating the acceleration of the water droplet fall, avoiding foam or water droplets remaining outside the inclined airbag 31 when it contracts, thus preventing residual water droplets from dripping, and preventing the water droplets from being carried into the front frame 22, playing a certain protective role for the third servo motor 23.

[0030] Please refer to Figure 1 、 Figure 9 and Figure 11, an embodiment provided by the present invention: an all-round foam spraying gantry for an automatic car wash machine, including a front rod 35 installed on the front of two sets of legs in the front of the outer frame 1. On the outer wall of the front rod 35 close to each other, a first detection unit 36 is installed. The first detection unit 36 includes a vertical frame and a first distance sensor and a first promptor embedded in the outer wall of the vertical frame. Inside the two sets of legs in the front of the outer frame 1, an electric push rod 37 is installed. The output end of the electric push rod 37 is installed with a sealing plate 38. An opening is provided on the opposite side of the two sets of legs, and the sealing plate 38 is used to block the opening. A second detection unit 39 is installed inside the legs. The second detection unit 39 includes a second distance sensor and a second promptor.

[0031] Further, after the vehicle travels between the two sets of first detection units 36, the first distance sensor is used to detect whether the vehicle drives into the area below the moving gantry 2 centered. When the numbers detected by the two first distance sensors are different, it means that the vehicle cannot be parked straight in the designated area below the moving gantry 2 according to the current moving state. The first promptor gives a prompt for vehicle position adjustment. And when the first detection unit 36 detects that a vehicle has driven in, the electric push rod 37 shortens, driving the sealing plate 38 to move upward, exposing the second detection unit 39. The second distance sensor in the second detection unit 36 is used to detect whether the vehicle makes a position adjustment. When the detection data obtained by the second distance sensor is different, a prompt is given again to ensure that the vehicle can be parked straight in the designated area. By setting the first detection unit 36 and the second detection unit 39, the vehicle position is detected during the vehicle movement process, so as to ensure that when the vehicle stops, it is in a straight state, rather than detecting the parking position and state of the vehicle after it stops, saving adjustment time and thus improving the vehicle washing efficiency.

[0032] Please refer to Figure 9 and Figure 10 , an embodiment provided by the present invention: an all-round foam spraying gantry for an automatic car wash machine, including a back rod 40 installed on the side where two sets of legs in the rear of the outer frame 1 are close to each other. On the front of the back rod 40, a protective frame 41 is installed. Inside the inner wall of the protective frame 41, a second telescopic rod 42 is installed. The output end of the second telescopic rod 42 is connected with a moving frame 43. The outer wall of the moving frame 43 is slidably connected to the inside of the protective frame 41. The moving frame 43 is a frame structure with openings on the front and bottom. A third detection unit 44 is installed inside the moving frame 43. The third detection unit 44 includes a position sensor and a third promptor. At the bottom of the top frame in the outer frame, a front box body 45 is installed. The back of the front box body 45 is connected with a rotating plate 48. Inside the inner wall of the front box body 45, a third telescopic rod 46 is installed. The output end of the third telescopic rod 46 is connected with an arc-bottom pushing block 47. The arc-bottom pushing block 47 is attached to the front of the rotating plate 48. On the front of the rotating plate 48, a fourth detection unit 49 is installed. The fourth detection unit 49 includes a thermal imaging sensor and a fourth promptor.

[0033] Further, when the second detection unit 39 detects that a vehicle has entered below the outer frame 1, the second telescopic rod 42 extends, pushing the moving frame 43 to move outward along the inside of the protection frame 41, pushing out the third detection unit 44. The front position of the vehicle head is detected through the in-place sensor. When the vehicle travels to the designated position, the third prompt device prompts the personnel to stop the vehicle and get off the vehicle in time. When the third detection unit 44 detects that the vehicle has been parked at the designated position, the third telescopic rod 46 extends, and the arc-bottom push block 47 is used to push the rotating plate 48 to rotate outward, exposing the fourth detection unit 49. Whether the personnel get off the vehicle is detected through the thermal imaging sensor, and the fourth prompt device is used to prompt the personnel to get off the vehicle. After the thermal imaging sensor detects that the personnel have got off the vehicle, the fourth prompt device prompts the personnel to check whether the vehicle doors and windows are closed, and then prompts the personnel to leave below the outer frame 1. When the fourth detection unit 49 detects that the personnel have left, the second telescopic rod 42 and the third telescopic rod 46 shorten, retracting the third detection unit 44 and the fourth detection unit 49, avoiding the occlusion by water flow and foam, which is beneficial to improving the detection effect.

[0034] Please refer to Figure 1 As shown in, an embodiment provided by the present invention: An all-round foam spraying gantry for an automatic car washer, including a servo motor four 50 installed on the back of the top frame of the outer frame 1. The output end of the servo motor four 50 is connected to a second lead screw 51, and the moving gantry 2 is sleeved on the outer wall of the second lead screw 51. The servo motor four 50 drives the second lead screw 51 to rotate, thereby driving the moving gantry 2 to move back and forth. The top wall of the moving gantry 2 is provided with a foam head 20 and a liquid spray head 21, and the liquid spray head 21 is located on both sides of the foam head 20. The foam head 20 is used for spraying foam on the car. Liquid spray heads 21 are also installed inside both sides of the moving gantry 2, and the liquid spray heads 21 are used for washing the car.

[0035] Working principle: When an omnidirectional foam spraying gantry for an automatic car washer is in use, the first detection unit 36 detects whether the vehicle drives in centered under the moving gantry 2 and detects the body width. According to the detection result of the body width, the distance between two sets of vertically arranged cleaning and protection components 15 is adjusted. The driver is prompted to adjust the vehicle position during driving according to the centered detection result. The second detection unit 39 detects again the centered state and the straight state of the vehicle body. The third detection unit 44 and the fourth detection unit 49 detect and prompt the personnel to park, get off, and the state of the doors and windows being closed. After that, the servo motor four 50 drives the lead screw four to rotate, so that the moving gantry 2 moves forward, and water is sprayed towards the vehicle body through the liquid spray head 21 to wet the vehicle body. Then, when the moving gantry 2 slides in the reverse direction, foam is sprayed on the vehicle through the foam spray head. After that, the vehicle is cleaned in four groups and the top by the cleaning and protection components 15. Finally, the vehicle is rinsed and water wax is sprayed through the moving gantry 2. After the vehicle cleaning is completed, the top liquid spray head 21 and the foam head 20 are shielded by the hollow arc plate 28 and the inclined airbag 31 to avoid wetting the personnel.
