Vehicle wash apparatus with an adjustable boom
View Patent ↗An automatic vehicle washing system is described. The vehicle washing system incorporates an elongated overhead cleaning platform for cleaning the front, top and rear surfaces of a vehicle. The overhead cleaning platform is attached to a single lift mechanism at a first end and is suspended from a belt at a second end, wherein the belt is also operatively connected to the first end. Accordingly, vertical movement of the lift actuator causes both ends of the platform to uniformly rise or descend. The platform further comprises a pivotal boom with fluid nozzles attached thereto, and a reciprocating pivotal actuator. The reciprocating pivotal actuator is capable of pivotal movement to any number of angular orientations within its operative range of motion. Advantageously, the pivotal and vertical positions of the nozzles can be independently varied, permitting the location of the overhead cleaning nozzles to be optimized for various vehicle profiles.
1. A method of washing a vehicle using an automated vehicle washing system, the vehicle having a rear end, a front end, and a length, the method comprising:
moving a gantry relative to the vehicle;
spraying cleaning solution from one or more nozzles of a plurality of nozzles, the plurality of nozzles being attached with the gantry, the plurality of nozzles being fluidly coupled to a source of cleaning solution; and varying the pressure of the cleaning solution sprayed from one or more nozzles of the plurality of nozzles based on one or more positions of the gantry, said gantry having a first position proximate to one of the front end or rear end of the vehicle, a second position proximate the other of the front end or rear end of the vehicle, a third position between said first and second positions, and a fourth position between said first and second positions and different from said third position, and wherein said pressure is varied at said third and fourth positions.
2. The method of claim 1 wherein said third position indicates a transition from one section of the vehicle having a height less than a predetermined vehicle distance to another section of the vehicle having a height equal to or in excess of the predetermined distance.
3. The method of claim 2 wherein the vertical distance is between 40″ and 46″.
4. The method of claim 2 further including determining a height profile of the vehicle along the length of the vehicle relative to the predetermined vertical distance.
5. The method of claim 1 wherein the fourth position indicates a transition from one section of the vehicle having a height equal to or greater than a predetermined vertical distance to another section of the vehicle having a height less than the predetermined vertical distance.
6. A method for washing a vehicle using an automated vehicle washing system, the vehicle having a rear end, a front end, and a length, the method comprising:
moving a gantry relative to the vehicle;
spraying cleaning solution from one or more nozzles of a plurality of nozzles, the plurality of nozzles being attached with the gantry, the plurality of nozzles being fluidly coupled to a source of cleaning solution; and varying the number of nozzles from which cleaning solution is sprayed based on one or more positions of the gantry, the gantry having a first position proximate to one of the front end or rear end of the vehicle, a second position proximate the other of the front end or rear end of the vehicle, a third position between said first and second positions and a fourth position between said first and second positions and different from said third position, and wherein said nozzles are varied at said third and fourth positions.
7. The method of claim 6 wherein said third position indicates a transition from one section of the vehicle having a height less than a predetermined vehicle distance to another section of the vehicle and having a height equal to or in excess of the predetermined distance.
8. The method of claim 6 wherein the fourth position indicates a transition from one section of the vehicle having a height equal to or greater than a predetermined vertical distance to another section of the vehicle having a height less than the predetermined vertical distance.
9. The method of claim 8 wherein the vertical distance is between 40 inches and 46 inches.
10. The method of claim 8 further including determining a height profile of the vehicle along the length of the vehicle relative to the predetermined vertical distance.
