Description

Technical Field

[0001] The present application relates to the field of vehicle cleaning, and in particular to a vehicle cleaning device and process. Background Art

[0002] The engineering car wash machine is a new type of environmentally friendly engineering vehicle washing equipment specially designed in recent years to target the dust pollution caused by industrial development. It has evolved from the old-fashioned car wash trough. It can automatically wash various types of engineering vehicles and completely solve the problem of road pollution caused by vehicles going out from urban construction sites. It is suitable for construction sites, garbage treatment plants, quarries, ports and docks, thermal power plants, steel mills, coal plants and other places with serious dust pollution.

[0003] At present, the engineering car washing machine includes a main frame, a top cleaning mechanism, a side cleaning mechanism and a bottom cleaning mechanism. The top cleaning mechanism is arranged on the top of the main frame and is used to clean the top of the vehicle, the side cleaning mechanisms are arranged on both sides of the main frame and are used to clean the two sides of the vehicle, and the bottom cleaning mechanism is arranged at the bottom of the vehicle and is used to clean the bottom of the vehicle. When washing the car, drive the vehicle to the car washing station, and then open each cleaning mechanism to clean the vehicle shell and chassis.

[0004] In view of the above-mentioned related technologies, the inventor believes that when cleaning the vehicle, although a bottom cleaning mechanism is provided, because the nozzle of the bottom cleaning mechanism is arranged upward, the water flows upward to wash the chassis, resulting in that the inside of the wheel hub is still difficult to clean. If dirt accumulates on the wheel hub, it may cause the wheel hub to be corroded and deformed, which may easily cause safety hazards. Summary of the invention

[0005] In order to facilitate cleaning of dirt inside the wheel hub, the present application provides a vehicle cleaning device and process.

[0006] In the first aspect, the present application provides a vehicle cleaning device, which adopts the following technical solution:

[0007] A vehicle cleaning device comprises a main frame, a top cleaning mechanism, a side cleaning mechanism and a bottom cleaning mechanism, and also comprises a wheel hub cleaning mechanism for cleaning the inner side of a wheel hub, wherein the wheel hub cleaning mechanism comprises a cleaning disc, a main pipe and a telescopic pipe; the main pipe is arranged on the ground, and the telescopic pipe is inserted into the main pipe; the telescopic pipe and the cleaning disc are connected by a bent pipe, and the cleaning disc is rotatably connected to the bent pipe, the cleaning disc is arranged parallel to the wheel hub, the cleaning disc is provided with a fan-shaped notch for the axle to be inserted into, and a reset structure for resetting the cleaning disc after rotation is provided between the cleaning disc and the bent pipe; a plurality of nozzles are provided on the cleaning disc, and the nozzles, the bent pipe, the telescopic pipe and the main pipe are all connected.

[0008] By adopting the above technical solution, when washing a vehicle, the vehicle is parked at the car wash station, the telescopic tube rises until the axle is stuck in the fan-shaped notch on the washing disc, and then water is passed into the main tube, and the water is sprayed out from the nozzle to wash the wheel hub and the frame. After the washing is completed, the vehicle moves, and the axle moves forward to push the washing disc to rotate, so that the axle is separated from the washing disc; the setting of the washing disc can increase the cleaning area of ​​the wheel hub, and the setting of the fan-shaped notch can reduce the interference of the washing disc on the axle, so that the axle can move forward smoothly when the vehicle moves.

[0009] Optionally, the reset structure includes a torsion spring 1, which is set on the bent pipe, and the two ends of the torsion spring 1 are respectively fixedly connected to the bent pipe and the cleaning disc.

[0010] By adopting the above technical solution, the setting of torsion spring 1 facilitates the resetting of the cleaning disc. When the axle moves to drive the cleaning disc to rotate, torsion spring 1 undergoes elastic deformation. When the axle is separated from the cleaning disc, the force of torsion spring 1 to restore the deformation drives the cleaning disc to reset, which is convenient for cleaning the next vehicle.

[0011] Optionally, a mounting seat is provided on the ground, the main pipe is hinged on the mounting seat, and a torsion spring 2 is provided between the mounting seat and the main pipe for resetting the main pipe after rotation; the wheel hub cleaning mechanism also includes a driving structure for driving the main pipe to rotate and a trigger structure for triggering the driving structure; the trigger structure includes a trigger column and a cavity 1, and a spring 1 for resetting the trigger column is provided between the trigger column and the cavity 1; the driving structure includes a driving rod and a cavity 2, the cavity 1 and the cavity 2 are connected through an air pipe, the trigger column is inserted into the cavity 1 in a vertical direction, the driving rod is inserted into the cavity 2, and when the trigger column moves downward, the driving rod extends out of the cavity 2.

[0012] By adopting the above technical solution, when the wheel of the vehicle presses on the trigger column, the trigger column moves downward, the spring one is compressed, the air in the cavity one enters the cavity two through the ventilation channel, the drive rod extends out of the cavity two, and the drive rod drives the main pipe to rotate, at this time the torsion spring one is deformed; when the vehicle leaves the trigger column, the force of the spring one to restore the deformation drives the trigger column to reset, and when the trigger column moves upward, the air enters the cavity one from the cavity two, and the force of the torsion spring one to restore the deformation drives the main pipe to rotate in the opposite direction into the support seat, so that the drive rod slides into the cavity two; the structure is simple, and the vehicle is used for driving, and there is no need to set up an additional drive.

[0013] Optionally, a second spring is provided between the telescopic tube and the main tube for returning the raised telescopic tube to its original position.

[0014] By adopting the above technical solution, when the telescopic tube rises, the second spring undergoes elastic deformation. After the telescopic tube finishes working, the force of the second spring to restore the deformation drives the telescopic tube to descend. The setting of the second spring facilitates the resetting of the telescopic tube.

[0015] Optionally, a membrane flap is provided at the bottom of the telescopic tube.

[0016] By adopting the above technical solution, when the water flow impacts the telescopic tube, the water flow first impacts the membrane petal, and the membrane petal is subjected to force to move the telescopic tube outward from the main tube until the bottom of the telescopic tube abuts the top of the main tube, and then the water flow continues to impact the membrane petal to open the membrane petal, and the water flow enters the telescopic tube; the setting of the membrane petal allows the telescopic tube to extend outward first and then let water pass, thereby increasing the water pressure and improving the impact force of the nozzle.

[0017] Optionally, the top surface of the trigger column is arranged in an inclined surface.

[0018] By adopting the above technical solution, the trigger column is arranged in an inclined surface, which makes it easy for the tire to press onto the trigger column.

[0019] Optionally, guide strips are provided on the ground.

[0020] By adopting the above technical solution, the setting of the guide strip facilitates the guidance of the vehicle and reduces the possibility that the tire fails to press on the trigger column.

[0021] In the second aspect, the present application provides a vehicle cleaning process, which adopts the following technical solution:

[0022] A vehicle cleaning process, the process comprising the following steps:

[0023] S1: Park the vehicle at the cleaning station;

[0024] S2: Start the top cleaning mechanism, the side cleaning mechanism and the bottom cleaning mechanism;

[0025] S3: The telescopic tube rises relative to the main tube, driving the cleaning disc to rise until the axle is stuck in the fan-shaped notch of the cleaning disc; the nozzle is started to spray water to the inner side of the wheel hub and the frame on the opposite side for cleaning;

[0026] S4: The vehicle moves, the axle moves forward, pushing the cleaning disc to rotate, the fan-shaped notch rotates, and the axle disengages from the fan-shaped notch and thus disengages from the cleaning disc;

[0027] S5: After cleaning is completed, all cleaning mechanisms are closed, the vehicle drives away, the reset structure drives the cleaning disc to reset, and the telescopic tube descends back to the initial position.

[0028] In summary, this application includes the following beneficial technical effects:
