    DEVICE FOR ACTING, LIFTING AND LAYING TILES
    The invention relates to a device for gripping, lifting and laying down paving material such as tiles, comprising a mobile frame on wheels, at least one suction head, comprising a flange with a circumferential wall extending along said peripheral edge and which is provided by a pneumatic conduit is connected to a vacuum pump which can create a vacuum under the suction head in the space formed by the flange, the peripheral wall and the top of the tile such that the top of a tile is engaged, the suction head of which is connected to the front the frame is connected, which arm is movable such that an engaged tile can be lifted and laid down.
    Such a device is described, for example, in NL-A-8901001. It is an object of the invention to provide a device that is strong, efficient, lightweight, simple and accurate to operate.
    The frame is preferably provided with front wheels arranged on a fixed axis near the front of the frame and with rear wheels arranged on axes pivotable about vertical axes near the rear of the frame. This makes it possible to control the device easily and accurately, so that the tiles, vowels and the like can be lifted and placed accurately in a simple manner.
    The arm is preferably movable by means of an electric motor. According to the invention, the arm is pivotally connected at one end to the front of the frame about a horizontal axis, and a telescopic rod is arranged between the frame and the arm to adjust the other end of the arm in height. The telescopic rod is preferably telescopically retractable and extendable by means of a screw. The telescopic rod is preferably provided with an electric motor for sliding the rod in and out. In alternative embodiments, the telescopic rod can also be moved by means of pneumatic or hydraulic pistons. Due to this construction, the device is light in weight and can be accurately operated. Furthermore, the pivotal movement of the arm ensures that the center of gravity of the load to be lifted is also closer to the frame when it is raised, so that the device can be maneuvered more easily.
    The front wheels preferably have a diameter that is larger than 30 cm. The front wheels are generally available bicycle wheels in the preferred embodiment. Due to the relatively large wheels, the device, when loaded with the tiles, clinkers and the like to be lifted, can easily be moved over bumps.
    The device preferably comprises a plurality of said suction heads. The suction heads are preferably attached to a horizontally extending tube, which forms part of the pneumatic line. The pneumatic line preferably comprises a flexible hose that extends between the vacuum pump and the movable end of the arm.
    The device is preferably provided with a fuel-supplied generator, which supplies electricity to the vacuum pump and / or the electric motor. The frame is preferably provided with at least one handle near the rear for maneuvering the device, wherein control buttons or control handles are arranged on or near the handle to operate the vacuum pump and / or the electric motor. The vacuum pump is preferably of the vacuum pump type.
    The invention will be illustrated with reference to figures shown in the drawing of an exemplary embodiment of a device for gripping, lifting and laying down tiles, in which:
    Figure 1 is a schematic perspective view from the rear of the device according to the device, and;
    Figure 2 schematically shows the front side of the device from Figure 1 in perspective;
    The device 1 comprises a frame 2 consisting of hollow metal tubes with a square cross-section. The frame 2 comprises a lower horizontally extending rectangular sub-frame 3 and an upper horizontally extending U-shaped sub-frame 4 of substantially equal dimensions, which are mutually connected at the corner points of the lower sub-frame by vertical tubes 5. The upper sub-frame 4 is between the front and rear with a transverse connecting tube. Furthermore, diagonal reinforcement tubes 7 are provided in the side faces of the frame.
    Bicycle wheels 8 are mounted on both sides on the front side of the frame 2 and have a diameter of approximately 60 cm. At the rear, the underside of the frame 2 is provided with downwardly extending pivot shafts 10 to which pivot wheels 9 are attached. The frame 2 is provided at the rear near the upper side with two rearwardly extending handles 11, which can be engaged by the user to control and operate the device 1. In this way the frame 2 can be moved, whereby the device 1 can be steered by pushing the rear side sideways.
    The frame 2 is provided on the front side, near the top side, with an arm 12 pivotable about a horizontal, laterally extending axis. The arm 12 consists of hollow tubes and is substantially V-shaped with the ends 13 opposite the point of the of the V-arm near the two sides of the top of the frame 4 are hinged. The tip of the V-arm therefore essentially extends forward and can be moved up and down by pivoting the arm 12. An electrically screw-out telescopic rod 14 is also pivotally mounted on a front side of the frame 2, near a lower side, about a horizontal laterally extending axis. The telescopic rod 14 is internally provided with a screw driven by an electric motor 16 to cause the rod to slide in and out. The other end of the telescopic rod 14 is hingedly attached to the V-shaped arm 12, near the tip 15 thereof. In this way the V-shaped arm 12 can be pivoted up and down by the electric motor 16.
    A hollow carrying tube 17 closed at both ends and extending laterally is hingedly connected to the tip 15 of the V-shaped arm by means of a rod 18 extending from the center thereof. Two tie rods 19 are provided between the ends of the support tube 18 and the end of the rod 17 for reinforcement. Four suction heads 20 are attached to the support tube 17 on the underside for engaging and lifting tiles 21, clinkers and the like. The suction heads 20 each comprise a round flange, a downward circumferential wall of which extends from the edges. The wall is provided with an elastic part on the underside, for example of rubber. The flanges are each provided with a central bore, which connect to bores in the carrier tube 17, so that an air passage is formed from each carrier head 20 from the carrier tube 17.
    The lower sub-frame 3 is provided with a horizontally extending carrier 3a on which a vacuum pump 22 is placed at the rear and a generator 16 at the front. The vacuum pump 22 is part of a commercially available vacuum cleaner. The generator 16 is also a commercially available generator 16, which converts a fuel such as diesel into electricity. The hose 23 of the vacuum cleaner, which is connected to the vacuum pump 22, is attached to the V-shaped arm 12 and is connected at the end to an opening in the middle of the support tube 17. The vacuum pump 22 can thus create a vacuum in the space between the flange, the peripheral wall and the upper surface of a tile 21, clinker and the like to be lifted.
    The handles 11 are provided with operating handles 11a and operating buttons. The electric motor 16 of the telescopic rod 14 can be operated with a control handle 11a and control button on the left handle, and the vacuum pump 22 of the vacuum cleaner can be switched on and off with a control handle 11a and / or button on the right handle.
    The device 1 described here is strong, efficient, lightweight and easy and precise to operate and maneuver.
