Description

The present invention relates to an underfloor cleaning apparatus for an automobile, and more particularly to a truck lifted by a plurality of rams located on a center line in the front-rear direction of the automobile and moving up and down from the floor. The under-floor cleaning device for cleaning the lower part of a large vehicle.

“Conventional technology” Conventionally, in the case of large vehicles, unlike the case of small vehicles,
If a wrist device of the type in which the entire vehicle is lifted by a plurality of arms is used for the purpose of cleaning, the equipment becomes considerably large, and therefore the cleaning device becomes very expensive.
Therefore, maintenance work such as repair and parts replacement is separated from car wash work, and a dedicated car wash space is provided for car wash work.
Prepare a set of platforms on which large vehicles can ride. For example, a pair of rails are laid between the platforms, and a washing machine sprays on the rails to reciprocate and wash the underfloor of large vehicles. It was common to do. On the other hand, for the inspection and maintenance work of large vehicles, from the viewpoint of safety, workability, and low equipment cost, a dedicated space for inspection and maintenance work is provided separately from the car wash space, where a ram is installed from the floor. A model in which two wrist devices that move up and down are embedded on the center line in the front-rear direction of the vehicle, one of which is a fixed-side lifting device, and the other is a movable-side lifting device that fits the length of the vehicle. Most popular

However, in the washing of large vehicles, the type of lifting device for inspection and maintenance work, in which the ram moves up and down from the floor on the center line of the vehicle as described above, is very popular. Cleaning work cannot be performed in the maintenance space, so a separate car wash space should be provided.
While there was a need to prepare ancillary equipment such as platforms, there was an economic demerit such that existing equipment that could be used in inspection and maintenance spaces could not be combined.
