Abstract

A portable tire washing apparatus is mounted on a towable trailer bed or on a platform and has drivable rollers for rotating truck tires while they are sprayed by jets of water. Additional roller assemblies or bumpers are provided to prevent sideway movement of the tires. The platform-mounted apparatus may be installed on level ground or in a depression dug in the ground.

Claims

1. A portable tire washing apparatus for washing tires on a vehicle, said apparatus comprising:

a portable support member which has a longitudinal and a transverse dimension;

vehicle entrance and exit ramps pivotably mounted on opposite transverse sides of said support member so that said ramps are movable between an operational outwardly extending ground-contacting position and a non-operational generally upwardly extending travel position;

at least two longitudinally spaced, tire-rotating, drivable roller cradle assemblies mounted on said support member so that they are in transverse alignment with said ramps in the operational position thereof, each of the cradle assemblies containing a transverse space;

liquid spraying means mounted in the transverse space;

means for driving the rollers of said cradle assemblies while liquid is supplied to said spraying means; and

means for mounting said cradle assemblies for rocking movement about axes extending in the longitudinal direction of said support member.

2. An apparatus as defined in claim 1, wherein said support member comprises a platform.

3. An apparatus as defined in claim 2, wherein said platform comprises the bed of a towable wheeled trailer.

4. An apparatus as defined in claim 1 or 2, wherein said ramps are removably mounted on said support member.

5. An apparatus as defined in claim 1, wherein the drivable rollers have a smooth surface.

6. An apparatus as defined in claim 1, wherein the drivable rollers are enrolled in cylindrical sleeves of expanded metal.

7. An apparatus as defined in claim 1, further comprising respective guide means, mounted adjacent said cradle assemblies, for preventing sideway displacement, in the longitudinal direction, of tires supported on said cradle assemblies.

8. An apparatus as defined in claim 7, wherein said guide means comprises tire-alignment roller assemblies mounted on said support member and disposed on transversely opposite sides of said cradle assemblies.

9. An apparatus as defined in claim 7, wherein said guide means comprises upwardly extending bumpers mounted on said support member and disposed on transversely opposite sides of said cradle assemblies.

10. An apparatus as defined in claim 1, 5, or 7, further comprising a ground-contacting nose portion pivotably connected to a free end of each ramp, and hydraulic means for moving said nose portion between an extended ground-contacting position in said operational position and a retracted position in said travel position.

11. An apparatus as defined in claim 1, further comprising four pivotably mounted protection gates for enclosing the area in which said cradle assemblies are disposed, when tires are being rotated and sprayed.

12. An apparatus as defined in claim 1, wherein each of said ramps comprises two sections and means for pivotably interconnecting said sections sot that one of said sections is elevatable, during a tire-washing operation, to form an upright protection shield for an area enclosing said cradle assemblies.

13. An apparatus as defined in claim 1, further comprising jack means, mounted on said support member, for leveling said support member relative to a ground surface on which said vehicle enters and exits said apparatus via said entrance and exit ramps, respectively.

14. An apparatus as defined in claim 1, further comprising:

tank means, mounted on said support member, for storing liquid;

pump means for supplying the stored liquid to said liquid spraying means;

collecting means for collecting debris-containing liquid resulting from washing of the tires; and

liquid-recycling means for removing debris from the liquid and returning clean liquid to said tank means.

15. An apparatus as defined in claim 1, further comprising:

conduit means, coupled to said liquid spraying means, for supplying liquid to said spraying means; and

coupling means, connected to said conduit means, for coupling said conduit means to an external source of liquid.
