Description

Positioning structure and lifting and lowering of a car and operator arranged on a platform located inside a paint booth and / or similar facilities.

Object of the invention

The present invention relates to a structure  positioning and lifting-lowering of a car and operator arranged on a platform located in the interior of a paint booth and / or facilities Similar.

Background to the invention

In conventional cabins normally require to make a civil work of approximately 30 cm on the ground deep and with a surface similar to the perimeter of the cabin.

In some cases this work is located below the  vehicle and has a much smaller but deep section considerable that can be 1 meter.

The purpose of this work is to allow the air which is blown into the cabin pass through the floor metallic that is made with grills and channeled to ducts and outside through what is called "plenum bottom suction. "

In some cases this civil work is not done and what is done is to raise the floor of the cabin about 30 cm in relation to the floor plan of the workshop.

To access the vehicle inside the cabin  there are ramps that can be outside the cabin or interiors

Once the vehicle is inside the cabin and in painting position, it is possible that the operator find that the roof of the vehicle is at a higher height so which is forced to climb on sidewalks, pedestals, etc. By other side when you need to paint the lower part of the body of the vehicle must crouch in a very forced posture or dispose of conventional elevators that lift the vehicle to a most comfortable working position.

To avoid these inconveniences, the structure of the invention that consists of installing within the paint booth a metal floor with one or more areas or its all grill to another carrier that support different loads managing to vary the position of the operator with respect to the car or vice versa according to work needs.

Description of the invention

The structure of the invention therefore it comprises a central platform, called a loading platform in the one that is positioned the vehicle, and another perimeter platform concentric called work platform where it goes positioned the operator (s).

This work platform can be integral or heading in several zones, in which case the different zones of the platform can relate to interlocks and move the work platform vertically.

In the area of the loading platform are arranged either hydraulic or pneumatic lifting means that displace vertically this platform and move the work platform to interlock with the loading platform.

The work platform is displaced by some vertical guides located near the perimeter of the cabin and they constitute a kind of posts that emerge from the floor of the same.

In profiles close to these guides is where produce the interlocks that fix the position of the platform of work in the two levels, superior and inferior, of work.

The outer perimeter of the loading platform is related to the interior perimeter of the platform work by means of a tarp that allows the air to be blown into inside the cabin and that it is led to the ducts of exit avoiding that it leaves by the free space between the platforms when they are at different heights.

To introduce the vehicle inside the cabin and on the loading platform, both platforms must be at its lower level for example about 10 cm from the floor and the vehicle accessed through a small wedge or ramp.

Once the vehicle is located on the platform both platforms that are interlocked are loaded, pins, pins, etc. This elevation point is up to get a height of approximately 30 cm with which get the "lower plenum".

At this point the cabin is already operational  to carry out the general painting of the vehicle.

If you want to paint the roof of the vehicle the operator will lift both platforms in solidarity to a height of about one meter, blocking by mechanical means or hydraulic work platform on the sides of the cabin, in the vertical guides through which said run platform and the loading platform is unlocked so that descends back to the lower level of height above the ground of 30 cm thus being at the right height to paint the ceiling of the vehicle.

Once the ceiling is painted, the operator lifts again the loading platform to the upper level and it is done in solidarity with the work platform that in turn is freed from the anchors on the sides of the cabin and both descend to the point or lower level of work.

In case it is necessary to paint the parts lower, the loading platform is raised to the upper level, the work platform being anchored to the sides of the cabin on said lower level.

Once the bottom of the vehicle is painted, the loading platform descends to the bottom point, to perform: retouching, unpacking, drying, etc.

After the painting process descends the set of the two platforms with a single lifting equipment which could be hydraulic, pneumatic, with pulleys and cables or depending on manufacturing costs could be done with independent lifting devices, one for the platform  load and another or more for the work platform.

In this position the work platform forms a single element but it can be formed by zones or portions independent related interlocking elements, such as those already mentioned, with the purpose of becoming zones Freelancers

Between both platforms and between the platform of work and the interior surface of the cabin, in the sense perimeter, flexible laminar surfaces are arranged, such as, tarps that close the spaces with a good seal cited and not only prevents air from flowing through the spaces  cited, but the air is forced to pass through the bottom of the platforms and also, it is led outwards.

Description of a practical example of realization of the invention

The structure of the invention is applied by example, to a paint booth 1 that has a generation and air inlet 2 from the top of the cabin and also it presents an interior perimeter lighting 3.

The cabin has a small entrance ramp 4 to facilitate the passage into the vehicle 5 when the structure of the invention itself is level lower.

The cabin has perimeter and preferably on its sides greater parallel vertical guides 6 and facing two to two that are part of the structure.

Through these guides the platform of work 7 to be hooked with the central loading platform 8, both platforms are part of the structure.

The loading platform 8 positions the vehicle 5 and said platform is displaced vertically by means of hydraulic cylinders 9 preferably in an arrangement of scissors.

Figures 1 and 2 represent different positions of platforms 7 and 8.

\hbox{rampa 4.}

Figure 1 shows the structure at its lower level, introducing and positioning the vehicle 5 on the loading platform 8 through the

 \ hbox {ramp 4.} 

Work platform 7 in position operational can reach two positions, one lower represented in figures 1, 2, 3 and 6 and another superior represented in the Figures 1, 2 and 4. In these two extreme positions the platform of Work 7 is hooked and the loading platform 8, unzipped from the work platform, it moves vertically to reach a higher position, figure 1 or lower figure 2, with respect to the work platform.

The lower working position is reached when  both platforms being crimped the elevation of the same from the lower level and a height is reached over said dimension of approximately 30 cm. At this point the work platform and when unloading the loading platform It rises to the top point.

At this top point of the loading platform the free space between both platforms is covered perimeter with a canvas 9a, flexible, elastic or similar surface, getting the air to its exit, well through the center of the loading platform or through the platform Work, as appropriate.

The loading platform 8 when descending and snag again with the work platform can jointly access to the upper end point and from the same once the loading platform is uncoupled and crimped the work is lowered the load and thus easily paint The roof of the vehicle.

The crimp consists of providing the platform of work of a series of bolts 10 that are operated and displaced by means of respective hydraulic cylinders 11 for that are interlocked or unlocked at points 12 of the platform load or in conformations 13 belonging to profiles 14 verticals that emerge in this direction from the floor of the cabin.

In addition, the work platform is equipped with profiles 15 that are coupled guided in profiles 14 with the purpose of the vertical displacement of the platforms They are perfectly balanced.

The work platform can be integral or be constituted of sections that can coincide in length with the sides of the rectangle that forms said work platform. He coupling and decoupling of the mentioned sections can be carry out by means of the corresponding bolts already mentioned.

Describe sufficiently the nature of the invention, as well as how to perform it in practice, should be noted that the provisions indicated above and represented in the attached drawings are susceptible to modifications of detail as long as they do not alter the principle fundamental.
