Description

Technical Field

[0001] This utility model relates to the field of car wash machine technology, specifically a rotary car wash machine. Background Technology

[0002] With the rapid growth of car ownership, automatic car wash machines have been widely used in the car wash market due to their efficiency, convenience, and labor-saving features. Among them, contactless car wash machines use a high-pressure spray system to atomize cleaning agents and water and spray them evenly onto the car surface. Relying on the combined action of chemical cleaning and physical impact, stains are removed. Since there is no need for brushes to touch the car body, the risk of scratching the paint is effectively avoided, making them popular with high-end car owners and car wash shops.

[0003] Currently, most mainstream contactless car wash machines on the market adopt a "crane + gantry" or "crane + partial frame" design. Specifically, this type of car wash machine typically features a crane structure spanning the wash aisle, which travels longitudinally (parallel to the vehicle's direction of travel) along tracks laid on the ground. The wash arms (usually including high-pressure spray booms) are mounted on the crane and can move laterally (perpendicular to the vehicle's direction of travel) or rotate. Through the combined motion of the crane's longitudinal movement and the wash arms' lateral movement / rotation, the spray mechanism ultimately covers and cleans the entire three-dimensional surface of the vehicle (length, width, and height).

[0004] However, this traditional structure relying on overhead cranes has several significant technical drawbacks: First, the overhead crane is a large metal frame, requiring a large amount of profiles, resulting in high material costs. It also necessitates a high-precision drive system and a robust foundation, further increasing the complexity and cost of manufacturing and installation. Second, the overhead crane's large size imposes stringent requirements on the height and width of the installation space, limiting its application indoors or in confined spaces and reducing site adaptability. Furthermore, driving the heavy overhead crane and washing arm requires a high-power motor, leading to high energy consumption; coupled with the fact that its traveling mechanism is in a humid environment, it is prone to rust and wear, increasing maintenance frequency and costs. Finally, traditional single-arm car wash machines have a relatively long spray path, leaving room for improvement in cleaning efficiency, making it difficult to efficiently cope with the ever-increasing traffic demands. Utility Model Content

The hot air dryer 52 can dry vehicles passing through the gantry frame 51; the two second motor sets 82 in the pair of drive moving mechanisms 8 operate independently.

[0023] Its detailed connection methods are well-known technologies in this field. The following mainly introduces the working principle and process, as follows: According to the instruction manual Figure 1-4As can be seen, when this utility model is in operation, the vehicle drives into the pair of arm mechanisms 9, that is, directly below the crossbeam 1. Of course, the initial position of the arm mechanisms 9 must allow the vehicle to enter; for example, the distance between the two arm mechanisms 9 is at its maximum, which is easily understood by those skilled in the art. The external water supply or cleaning fluid supply pump system is started. The pump system is connected to the arm mechanisms 9 through the connector mechanism 2 and the hose, and can spray water or cleaning fluid. This technology is existing technology. At the same time, the drive rotation mechanism 3 is started. Under the action of the rotation limit mechanism 4, the pair of crossbeams 10 are driven to rotate. Since the pair of crossbeams 10 are centrally symmetrical with respect to the axis of the rotation limit mechanism 4, and the bottom of the pair of crossbeams 10 are respectively connected to the sliding moving mechanism, the moving plate 7, the main shaft 13 and the arm mechanism 9, the initial position of the two arm mechanisms 9 is also centrally symmetrical, and they rotate with the axis of the rotation limit mechanism 4 as the center, that is, they rotate while cleaning. Of course, the arm mechanism 9 is equipped with a sensor 11 to monitor the distance between itself and the vehicle, and to transmit signals to the external control system to control the operation of the drive moving mechanism 8, so that the drive moving mechanism 8 drives the moving plate 7, the main shaft 13 and the arm mechanism 9 to move in the left and right directions, thereby adjusting the distance between the arm mechanism 9 and the vehicle to avoid collision with the vehicle body, or to avoid being too far away and affecting the cleaning effect. The signal transmission of the sensor 11 and the external control are existing technologies.

[0024] Specifically, the driving moving mechanism 8 includes a second motor set 82, a driving synchronous pulley 83, a pair of auxiliary synchronous pulleys 84, and a synchronous belt 85. A fixed plate 81 is fixedly installed on the front end face of the moving plate 7. The second motor set 82 is fixedly installed on the bottom surface of the moving plate 7 and on the side close to the fixed plate 81. The output end of the second motor set 82 rotates through the fixed plate 81 and is fixedly connected to the driving synchronous pulley 83. The pair of auxiliary synchronous pulleys 84 are rotatably installed on the fixed plate 81 and are respectively located at the upper left and upper right positions of the driving synchronous pulley 83. Fixed seats 86 are fixedly installed at both ends of the front side wall of the cross frame 10. The two ends of the synchronous belt 85 are fixedly connected to the fixed seats 86 and the synchronous belt 85 is meshed with the driving synchronous pulley 83 and the auxiliary synchronous pulleys 84. The operation of the second motor set 82 can drive the fixed plate 81 and the moving plate 7 to move left and right.

[0025] During operation, the output of the second motor unit 82 drives the active synchronous pulley 83 to rotate. Since the active synchronous pulley 83 meshes with the synchronous belt 85, and the fixed plate 81 and the moving plate 7 are horizontally and movably connected to the crossbeam 10 via the sliding limit mechanism 6, the active synchronous pulley 83 can move on the synchronous belt 85. Simultaneously, a pair of auxiliary synchronous pulleys 84 clamp the synchronous belt 85, increasing the contact area between the active synchronous pulley 83 and the synchronous belt 85, ensuring effective transmission. This drive mechanism 8 drives the arm mechanism 9 at the bottom of the moving plate 7 to move the plate 7, which is completely different from an overhead crane. This utility model, by eliminating the overhead crane and its corresponding structures and adopting a rotation and arm movement mechanism, results in a lighter overall structure, reduced installation space requirements, material savings, lower costs, and greater applicability. It also reduces the drive load, lowers motor power requirements, and increases energy efficiency. The simplified mechanical structure reduces the number of vulnerable parts, resulting in a lower failure rate in humid environments and a significant reduction in maintenance costs and frequency. In addition, the dual-arm collaborative operation of this utility model can cover a larger area at the same time, shorten the time of a single car wash, significantly improve cleaning efficiency, and help increase the number of vehicles served and the operating income of car wash shops per unit time, thus improving efficiency.

[0026] The drive rotation mechanism 3 includes a first motor assembly 31 and a rotating shaft 32. The first motor assembly 31 is fixedly installed at the center of the top of the crossbeam 1.

The inner ring of the fixed ring 41 is provided with a connecting plate and is fixedly connected to the lower end of the rotating shaft 32 through the connecting plate.

[0027] During operation, the first motor unit 31 drives the rotating shaft 32 to rotate, which in turn drives the rotating ring 44 to rotate, thereby driving the crossbeam 10 and the bottom parts of the crossbeam 10 to rotate. The fixed ring 41 is fixed to the crossbeam 1, and the fixed ring 41 and the rotating ring 44 are slidably connected through the slide body 43 and the annular guide rail 42, which ensures the stability of the rotating ring 44 during operation and also ensures stable support for components such as the crossbeam 10 and the boom mechanism 9.

The high-pressure arm 91 is fixedly connected to the lower end of the main shaft 13, and the low-pressure arm 92 is fixedly installed on the side wall of the high-pressure arm 91. The connection and shape of the high-pressure arm 91 and the low-pressure arm 92 are the existing car wash arm structures. They adopt continuous spray bars with nozzles.

In addition, the connector mechanism 2 includes a high-pressure water inlet rotary connector 21, a support slip ring 22, a conductive slip ring 23, a low-pressure water inlet connector 24, a low-pressure water outlet tee 25, and a high-pressure water outlet tee 26.

The sensor 11 is fixedly installed on the side wall of the high-pressure arm 91.

[0031] During operation, the external pump system for supplying cleaning fluid is connected to the low-pressure water inlet connector 24. The cleaning fluid, including no-rub liquid, soft water, and water wax, is supplied via a hose, a low-pressure water outlet tee 25, and a hose to the low-pressure connector on the low-pressure arm 92. The external water supply pump system is also connected to the high-pressure water inlet rotary connector 21. This system, via a hose, a high-pressure water outlet tee 26, and a hose to the high-pressure connector on the high-pressure arm 91, enables high-pressure water spraying to rinse away dirt after cleaning. This connection allows for 360-degree rotation and provides the necessary cleaning fluid and high-pressure water during the car wash process.

[0032] Mounting seats 93 are provided on the high-voltage boom 91 and the low-voltage boom 92 for mounting protective housings, which protect the booms and the vehicle and also enhance aesthetics. The sensor 11 can be an ultrasonic sensor, which offers accurate measurement, low cost, and wide applicability.

[0033] The drying mechanism 5 includes a gantry frame 51 and a hot air dryer 52. The gantry frame 51 is located in front of the support column 12 and the crossbeam 1. The hot air dryer 52 is installed on the gantry frame 51 and can dry vehicles passing through the gantry frame 51.

[0034] During operation, the vehicle slowly drives out of the gate frame 51, and the hot air dryer 52 dries the exterior of the vehicle. The structure is simple, the effect is good, and it is easy to repair and maintain.

[0035] In this invention, the two second motor sets 82 in the pair of drive moving mechanisms 8 operate independently, and the sensors 11 on the two arm mechanisms 9 control the corresponding second motor sets 82 to ensure the distance between the two arm mechanisms 9 and the vehicle. In this way, even if there is a certain range of deviation when the vehicle is parked, the applicability of this invention is improved.
