Device for assisting in positioning a mobile mounting vehicle and using the same.

BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a device for assisting in positioning a mobile mounting carriage for coupling with and handling an element, the device comprising a combination of a tool interchangeable mounted on the lifting device of the mounting carriage consisting of a mounting plate provided with a system of light sources therein. in the form of a light intersection, the center projects onto the element to be mounted with the mounting carriage, which system of light sources comprises a number of light sources which are adjustably mounted on previously mentioned mounting plate and are displaced at an angle (here called angle of light) from one another in mounting plate plan and each emits a narrow striped light cone (light bar) emitted in fan form from the light source.

It is known from a number of technical areas to use laser light projection on measuring equipment and workpieces to optimize the precision of the work process. These include transport, surveying, rotary saws, drills (also for mining), etc.

For example, U.S. Patent Application No. US 2012/0060383 A1 discloses a forklift control system that uses visible light from multiple light sources adjustably mounted on a backplate between the forks to provide projected light visual indicators that strike , dots, intersections or other figures, to assist the operator in determining the position of the forks in relation to the distance to the pallet rack and to the height of the fork openings in the pallets. However, this technique has the disadvantage that, with the described design, it is not useful for projecting an exact sighting cross for a mandrel on a workpiece to be handled, such an intersection would only be precise at a certain distance from the mandrel.

The object of this invention is therefore to provide a device which uses the projecting principle to also be able to provide a (light) screen junction precisely off the tip of the mandrel regardless of the distance to the workpiece to be handled with this mandrel.

This is to improve the mandrel tool for the mobile assembly wagon described in DK patent 178134 B1, in order to increase the efficiency of this mandrel tool and thereby of the entire mobile assembly wagon.

The object of the invention is met by a device of the type specified in the preamble of claim 1, characterized in that all the light sources are mounted around a mandrel projecting perpendicularly from the center of the mounting plate and that the center of the light line is towards the tip thereof. mandrel, so that one leg in said fan shape appears as a line of light exactly longitudinally of the mandrel and beyond its free end.

These intersecting light cones thereby project a light intersection that marks a target point for the mandrel, up to the element to be handled, this means that ice can be more easily hit with the mandrel without having to drop the carriage to control where the mandrel strikes, which helps to save time, thereby increasing the construction speed.

Claims 2 and 3 and 4 indicate further suitable embodiments.

Claim 5 indicates the use of the invention.

The invention is described in greater detail below with reference to the drawings, in which:

FIG. 1 shows the structure of the device incl. profile junction with mandrels and location of light sources

FIG. 2 shows the use of the device where the light cross is centered in the borehole of a building element, while

FIG. 3 is a side view of the mobile mounting car known from DK patent 179134 B1

Figure 1 shows a sketch of the structure of the mandrel tool comprising a mounting plate designed as a profile cross (1) with a mandrel / pin (3) located in the middle and protruding perpendicularly from this junction (2). The adjustable light sources (2) shown here in a preferred design with two light sources are mounted on the profile junction (1) at approximately the same distance from the center of the mandrel (the distance from the individual light source to the center is not important for the function and therefore may be different in other designs) and offset from each other at an angle (angle of light) which in the preferred embodiment shown here is 90 ° (but also other angles may be just the angles of intersection at one point), see Figure 1 and 2 as two rod-shaped objects pointing towards the free end of the mandrel (3) each emit a fan-shaped light cone into a flat plane whose propagation is determined by the light opening in the light source; these two '' light planes '' are e.g. as shown in Figure 1, turned approx. 90 ° relative to each other and each appears as a narrow line of light where they strike something reflective.

One leg in each '' light plane '' indicates a strip on the profile cross (1) in the direction from the light source (2) to the foot of the mandrel (3) where it is located on the profile cross and continues out of the mandrel (3) in exactly the same direction as this. This construction is described here with the two fan-shaped striped light cones whose planes are turned at an angle of approx. 90 ° with respect to each other and where both fan-shaped striped light cones have planes in exactly the same direction as the mandrel (3) will produce a light junction marking a fixing point for the mandrel (3) where the light junction strikes a reflective material.

Figure 2 shows an application of the improved mandrel tool of the present invention, showing that the profile cross (1) with mandrel (3) and light sources (2) has produced a light cross in a drilled hole (5) in a plate element (4), show the traffic light according to the invention used as a sieve for the mandrel (3) so that, far from the element (4) to be handled, the drive can be adjusted so that the element (4) can be hit exactly where you want the mandrel (3) to hit and without to release the trolley to see where the mandrel (3) hits.

Figure 3 shows a sketch of the mobile mounting wagon known from DK patent 179134 B1, forming a backdrop to the invention described herein, from the side and where the mandrel tool is used so that the mandrel (3) holds the building element (4).
