Description

Technical Field

[0001] The utility model relates to the field of car washing machines, in particular to a single-cantilever car washing machine. Background Art

[0002] With the sustained rapid growth of my country's economy and the continuous improvement of people's living standards, the number of cars has continued to increase, and people have also put forward new requirements for car washing. Not only must the car be washed cleanly and quickly, but it must also follow the principle of water conservation. Automatic car washing systems have also quickly emerged, mainly divided into traditional brush washing and contactless washing that has emerged in recent years. Although brush washing is more thorough, it takes a long time to clean and will cause certain damage to the car paint. Contactless cleaning technology has the advantages of no need to wipe and avoid scratching the car paint. However, the overall length of the single cantilever and double-sided cantilever on the market is relatively long, and most of them are double-track walking frames. The overall equipment is large and the cost is high. It is not suitable for assembly and car washing in small venues. The overall length of the single cantilever and double-sided cantilever is long, and there is a risk of collision between the cantilever and the side of the car. At the same time, the overall length is long, which makes the entire cleaning process use more water. Utility Model Content

[0116] When positioning the vehicle, in the initial state, the spray cantilever 4 is arranged parallel to the portal frame 101, the vehicle stops in the portal frame 1, the traveling mechanism 2 moves to the rear position of the vehicle, the position of the rear of the vehicle is located by the position sensor 10, and the traveling mechanism 2 stops moving;

[0117] When washing the vehicle, the traveling mechanism 2 moves to the front position, and the cantilever 4 sprays and washes the vehicle. When the traveling mechanism 2 moves to the front end limit position, the first drive motor 19 drives the cantilever 4 to rotate 180 degrees (the angle of rotation of the cantilever 4 is controlled by the angle sensor 30), and then the traveling mechanism 2 moves to the rear position of the vehicle, and the cantilever 4 sprays and washes the vehicle. When the traveling mechanism 2 moves to the rear position of the vehicle (the vehicle is positioned by the position sensor 10), the first drive motor 19 drives the spray cantilever 4 to rotate 180 degrees, and the cantilever 4 is reset to complete the washing.

[0118] Technical features not described in the present invention can be achieved through or by adopting existing technologies, and will not be elaborated here. Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
