Technical Field

[0001] The present application relates to the field of car washing, and in particular to a car washing factory. Background Art

[0002] For vehicles with cargo boxes, such as garbage trucks, road sweepers, vegetable and fruit trucks, etc., the cleaning of such vehicles generally includes two parts. The first part is to clean the exterior of the vehicle, and the second part is to clean the cargo box. In the related art, the exterior of the vehicle is generally cleaned with a traditional car washing machine, and the cargo box is generally cleaned with a robotic arm, that is, a nozzle is installed on the robotic arm, and then the robotic arm is extended into the cargo box to clean the inside of the cargo box through the nozzle.

[0003] With regard to the above-mentioned related technologies, two sets of equipment are used for cleaning the outside and inside of the cargo box, which occupies a large space. On the other hand, when multiple sets of equipment are used, more installation materials are required, resulting in increased installation costs. Summary of the invention

[0004] In order to improve the problems existing in using two sets of equipment to clean the exterior of a vehicle and the interior of a vehicle cargo box respectively, the present application provides a car wash factory.

[0005] The present application provides a car wash factory, which adopts the following technical solution: A car wash factory comprises a gantry, a telescopic component is slidably connected to the gantry in a vertical direction, and the telescopic component is driven to move vertically by a driving component 1, a water spray frame is installed at the telescopic end of the telescopic component, a plurality of nozzles 1 are connected to the water spray frame, water is supplied to the water spray frame by a water pump so that the nozzle 1 sprays water, two slide seats are slidably provided on the water spray frame, and the slide seats are driven by a driving component 2, a cleaning side roller is rotatably connected to the slide seat, and the cleaning side roller is driven by a driving component 3, the length direction of the cleaning side roller is arranged along the height direction of the vehicle, the two slide seats can slide close to or away from each other so that the two cleaning side rollers can respectively abut against the two sides of the length direction of the vehicle, and the two cleaning side rollers can approach each other so that the water spray frame can enter the vehicle cargo box.

[0006] By adopting the above technical scheme, when cleaning the outside of the vehicle, the height of the water spray frame is adjusted by driving component 1, and then the telescopic component is extended to drive the water spray frame to move until the cleaning side rollers on both sides of the water spray frame are respectively located on both sides of the vehicle, and then the sliding seat is driven by driving component 2 to slide so that the two cleaning side rollers are close to each other until the cleaning side rollers abut against the outer wall of the vehicle, and then in the process of the telescopic component continuing to extend, the driving component 3 is used to drive the cleaning side rollers to rotate, and at the same time, the water pump can be turned on, and the water spray frame and nozzle 1 are used to spray water on the vehicle to clean the outer wall of the vehicle; when cleaning the inside of the vehicle cargo box, the water spray frame is moved to the entrance of the vehicle cargo box, and the driving component is used to drive the cleaning side rollers to rotate. Component one adjusts the height of the water spray frame, and then uses driving component two to bring the two slides closer to each other, and then uses the telescopic component to extend the water spray frame into the vehicle cargo box, and uses driving component two to make the cleaning side roller abut against the inner wall of the vehicle cargo box. In the process of the telescopic component driving the water spray frame to move, the driving component three is used to drive the cleaning side roller to rotate. At the same time, the water pump can be turned on, and the vehicle can be sprayed with water using the water spray frame and nozzle one to clean the inner wall of the vehicle cargo box. The cleaning work of the vehicle exterior and the vehicle cargo box interior can be completed through a set of equipment (i.e., the gantry, the water spray frame and the cleaning side rollers), which occupies a relatively small amount of workpieces, and at the same time reduces the use of installation materials, saving installation costs.

[0007] Optionally, a mounting seat is provided on the water spray rack, and a telescopic member is rotatably connected to the mounting seat, and the telescopic member is driven to rotate by a driving component four, and the rotation axis of the telescopic member is arranged along the width direction of the vehicle, and the telescopic end of the telescopic member is fixedly connected to a fixed seat, and a cleaning roller is rotatably connected to the fixed seat, and the cleaning roller is driven by a driving component five, and the length direction of the cleaning roller is arranged along the width direction of the vehicle.

[0008] By adopting the above technical scheme, when cleaning the exterior of the vehicle, the cleaning side rollers are responsible for cleaning the exterior side walls of the vehicle, and the cleaning flat rollers are responsible for cleaning the exterior top wall of the vehicle. During cleaning, the drive component four is used to drive the telescopic part to rotate, and the position of the cleaning flat roller is adjusted by the telescopic part so that the cleaning flat roller abuts against the exterior top wall of the vehicle. Therefore, in the process of driving the water spray frame to move by the telescopic component, the drive component five is used to drive the cleaning flat roller to rotate, and the top wall of the vehicle can be cleaned; when cleaning the bottom wall or top wall of the vehicle cargo box, after the water spray frame enters the vehicle cargo box, the moving component four can be used to drive the telescopic part to rotate, and the position of the cleaning flat roller can be adjusted by the telescopic part so that the cleaning flat roller abuts against the top wall or bottom wall of the vehicle cargo box.

[0009] Optionally, the mounting seat is slidably connected to the water spray frame along the width direction of the vehicle, and the mounting seat is driven by a driving component six.

[0010] By adopting the above technical solution, the driving component six can drive the mounting seat to move, thereby increasing the cleaning range of the cleaning flat roller and reducing the length of the cleaning flat roller as much as possible.

[0011] Optionally, the telescopic assembly includes multiple telescopic sections, which are sequentially connected end to end, and adjacent telescopic sections are restricted from separation by an anti-detachment structure. Airways are opened in the telescopic sections, and the airways of adjacent telescopic sections are connected and both ends of the telescopic assembly are closed. An air pump for inflating or deflating the airways is provided on the gantry.

[0012] By adopting the above technical solution, when the telescopic component drives the water spray frame to move, air is injected into the airway through the air pump, so that the telescopic component can be extended under the action of air pressure, and the telescopic component can be shortened by pumping air from the airway through the air pump. The telescopic component has a simple structure and is easy to operate.

[0013] Optionally, the driving component 2 adopts cylinder 1.

[0015] Optionally, a fixed end of the cylinder is fixedly connected to the water spray rack, a second nozzle is fixedly connected to the slide seat, and a telescopic end of the cylinder is telescopic so that the second nozzle faces the outer wall of the vehicle or the inner wall of the vehicle cargo box.

[0016] By adopting the above technical solution, the nozzle 2 on the cylinder 1 can spray water to the outer wall of the vehicle, thereby improving the cleaning efficiency of the outer wall of the vehicle.

[0017] Optionally, the cleaning side roller includes a main roller and an extension section, the main roller is rotatably connected to a slide seat, and the extension section is connected to the lower end of the main roller via a connecting component.

[0018] By adopting the above technical scheme, since the height of the vehicle is higher than the height inside the vehicle cargo box, if a longer inclined side roller is used to perform a more comprehensive cleaning of the vehicle exterior, the inclined side roller cannot enter the vehicle cargo box, and when a shorter inclined side roller is used to clean the vehicle exterior, it cannot be fully cleaned. By setting the extended section, when cleaning the outer wall of the vehicle, the extended section is connected to the lower end of the main roller through the connecting assembly. After cleaning the outer wall of the vehicle, the extended section is removed so that the main roller can enter the vehicle cargo box to clean the inner wall of the vehicle cargo box. By setting the extended section, on the one hand, a more comprehensive cleaning of the outer wall of the vehicle is guaranteed, and on the other hand, the main roller can enter the inner wall of the vehicle cargo box to clean the inner wall of the vehicle cargo box.

[0019] Optionally, the connecting component adopts an electromagnet.

[0020] By adopting the above technical solution, when the main roller needs to be lengthened, the extension section can be installed on the main roller through the electromagnet. When the lengthened roller needs to be removed, the electromagnet can be powered off after the water spray frame is moved to the appropriate position. The connecting component has a simple structure and is easy to operate.

[0021] In summary, this application includes the following beneficial technical effects: 1. This application uses a gantry, a water spray rack and a cleaning side roller to complete the cleaning of the vehicle exterior and the interior of the vehicle cargo box with one set of equipment, which occupies a relatively small amount of workpieces, reduces the use of installation materials, and saves installation costs; 2. The present application ensures a more comprehensive cleaning of the outer wall of the vehicle by setting up the extended section, on the one hand, and on the other hand, the main roller can enter the inner wall of the vehicle cargo box to achieve the cleaning of the inner wall of the vehicle cargo box.
