Description

Technical Field

[0001] This utility model relates to a car body cleaning device, and more particularly to a semi-automatic cleaning device for cleaning the body of a bus. Background Technology

[0002] In urban public transport operations, to provide citizens with a pleasant riding environment, bus companies require all operating vehicles to be kept clean, hygienic, and disinfected, both inside and out. To achieve this, car wash areas are set up in bus company parking lots, staffed with cleaning personnel. Buses need to return to the car wash area for cleaning after rain or after a period of operation. Current vehicle cleaning methods primarily involve manually rinsing the vehicle with a handheld high-pressure water gun and then using a handheld brush to wipe it dry. This process is time-consuming, labor-intensive, and wastes a significant amount of water, while also polluting the car wash area. Existing technology also includes semi-automatic mobile car wash equipment. This equipment is typically mounted on a manually pulled car wash cart with a gantry frame. A washing roller brush is located in the center of the gantry frame, and spray nozzles are mounted on the gantry columns. During washing, the car wash cart is manually moved next to the bus, and the spray nozzles and roller brush are activated. Switch on, spray water onto the vehicle body, the roller brush starts to roll, and at the same time, the cleaning of a certain side of the car body is achieved by manually moving the trolley; however, these cleaning equipment have the following problems: (1) The distance between the bus body and the cleaning trolley is judged by the operator's eyes or experience, and there are often misjudgments, resulting in the car body not being cleaned thoroughly, especially when a certain part of the body is seriously dirty, it is necessary to clean it a second or multiple times, which wastes manpower and resources; (2) The height of the cleaning gantry of the existing equipment trolley is fixed, but there are many types of buses with different heights. When the height of the bus being cleaned changes, these semi-automatic car wash equipment cannot adapt to the height requirements of the car, so that the upper part of the car body cannot be cleaned; (3) According to the cleaning requirements of the bus after cleaning, the car body glass should be free of water stains after cleaning. The existing equipment does not have the means to remove water stains; after cleaning, a large amount of water stains remain on the glass, which needs to be cleaned manually, increasing the workload of the on-site operators.

The lower end of the water stain removal roller brush 23 is connected to the lower end bearing slider 22 of the water stain removal roller brush. The upper end of the water stain removal roller brush 23 is connected to the downward-extending output shaft of the water stain removal roller brush drive motor 21. The water stain removal roller brush drive motor 21 is electrically connected to the electronic controller. The water stain removal roller brush 23 can be rotated by the control buttons on the control panel 3 to remove water stains from the washed car body.

[0011] A first semi-circular cover 24 is suspended from the lower surface of the first slider 10, and the first semi-circular cover 24 is movably engaged with the left semi-circular backrest of the double semi-circular backrest seat 29; a second semi-circular cover 25 is suspended from the lower surface of the second slider 20, and the second semi-circular cover 25 is movably engaged with the right semi-circular backrest of the double semi-circular backrest seat 29. A horizontal electro-hydraulic cylinder 26 is provided on the top surface of the double semi-circular backrest seat 29. The second semi-circular cover 25 is connected to the rear arc-shaped vertical surface of the first semi-circular cover 24 and the second semi-circular backrest seat 29. A semi-circular pusher 27 is connected between the rear arc-shaped facade of the semi-circular cover 25, and the output shaft of the horizontal electro-hydraulic cylinder 26 is connected to the semi-circular pusher 27. A nozzle 12 and a first distance sensor 13 are respectively installed on the column of the cleaning roller brush gantry 8, and a second distance sensor 17 is installed on the column of the water stain removal roller brush gantry 16. The first distance sensor 13, the second distance sensor 17 and the horizontal electro-hydraulic cylinder 26 are respectively electrically connected to the electronic controller.

[0012] The first slider 10, the first semi-circular cover 24, the cleaning roller brush 15, and the lower bearing slider 14 of the cleaning roller brush form a whole. This whole can slide in the front-back direction between the first slider parallel guide rail 9 and the first horizontal front-back guide rail 7, thereby changing the distance between the cleaning roller brush 15 and the vehicle body. The second slider 20, the second semi-circular cover 25, the water stain removal roller brush 23, and the lower bearing slider 22 of the water stain removal roller brush form another whole. This whole can slide in the front-back direction between the second slider parallel guide rail 18 and the second horizontal front-back guide rail 19, thereby changing the distance between the water stain removal roller brush 23 and the vehicle body. After the trolley box 1 is moved to the outside of the vehicle body to be cleaned by the push handle 2, the first distance sensor 13 and the second distance sensor 1... 7. The distance between the two roller brushes and the vehicle body can be measured, and the measured signal is transmitted to the controller. The controller can control the output shaft of the horizontal electro-hydraulic cylinder 26 to extend forward or retract backward. The output shaft of the horizontal electro-hydraulic cylinder 26 pushes the first semi-arc cover 24 and the second semi-arc cover 25 to move forward or backward through the semi-U-shaped push frame 27, so that the first slider 10 and the second slider 20 move synchronously, thereby driving the cleaning roller brush 15 and the water stain removal roller brush 23 to move synchronously. Since the weight of the roller brush is mainly borne by the upper slider, during the above movement, the lower bearing slider 14 of the cleaning roller brush moves along the first horizontal front and rear guide rail 7. Similarly, the lower bearing slider 22 of the water stain removal roller brush also moves along the second slider parallel guide rail 18.
