Definitions
- the invention relates to a lifting and swiveling device for objects, in particular motor vehicles and the like, with essentially horizontally extending tie rods, with a frame which can be pivoted about an essentially horizontal axis of the tie rods and with a lifting device which is arranged in an
- the main horizontal axis of the tie rods is pivotable and is articulated to the frame by means of a bracket which can be moved along it, the bracket being designed to be displaceable along the lifting device by means of an actuating device and lockable at any point.
- Such a lifting device is known from EP-A 0 285 292. There, it is used exclusively to tip a vehicle to which a so-called “car cradle” is attached in order to avoid manual tipping. The lifting device is then removed and the car lies on the car cradle.
- Disadvantages of this device are the lack of a connection between the cradle and the lifting device when lifting and the risk of the car tipping over after the lifting device has been removed.
- the invention aims to provide a device of the type mentioned at the outset which overcomes the disadvantages of avoids previously known solutions and is convenient to operate and. is safe during every phase of use.
- the frame is a tenter frame which, on its side facing away from the lifting device, has a support frame which is essentially bent by 90 ° and then runs in a straight line again, and in that fastening devices for fixing are attached to the tenter frame of the too. tilting object are provided. That is why it is also mentioned in the description and the claims.
- the invention thus relates in particular to a four-point tilting device for motor vehicles, trailers, wagons, machines and components, consisting of the tensioning frame, which can be pivoted into the dead center via a lifting device connected to it in an articulated manner
- the device preferably having a device through which the objects to be processed, if they are motor vehicles, can enter the tilting device and by means of a Clamping device can be fixed to the tenter frame of the tilting device without dismantling the wheels and can be brought into position required for processing by a person with little effort by means of a winch or similar lifting device, with an overturning safety device preventing the overturning.
- the return to the starting position takes place by returning the lifting device.
- a safety device takes into account that the different dimensions of the objects to be tilted, in particular motor vehicles, result in different tilt angles corresponding to their different centers of gravity, which result in a variable tilt angle. need adjustment to prevent overturning safely.
- the tilting device according to the invention is characterized in particular by the fact that an adjustable tilt-over prevention reliably prevents the risk of tilting over and can be adapted to all different tilting angles.
- the tensioning frame is preferably connected to the lifting device by means of tie rods in such a way that the tie rods are articulated on the tensioning frame in the middle of the set track width, so that the lifting device is always vertical at every tilt angle.
- the tilting device according to the invention is independent of location and can be set up and operated on a flat surface at the place of use required in each case.
- FIG. 1 shows a device according to the invention together with a vehicle in the entry position and in the tilted position
- FIG. 2 shows a schematic view of a device according to the invention with the drawbar pivoted out
- FIG. 3 shows a clamping frame in plan view
- FIG Entry and exit ramp in section and in plan view
- FIG. 5 a support frame in side view and plan view
- FIG. 6 an extension arm which is mounted on the support frame
- FIG. 7 a lifting device
- FIG. 8 that of the Lifting device facing end of the tensioning frame
- FIG. 9 shows a clamping rail for the object to be tilted
- FIG. 10 shows a view of the tensioning frame from the front
- FIG. 11 shows a view of an end of a variant of the
- FIGS. 12 and 13 two variants of a clamping device.
- the object to be tilted is fastened to a tensioning frame 4 by means of tensioning chains or straps 14.
- the clamping frame 4 is provided with a support frame, which can either be made in one piece or not with it.
- the clamping frame is articulated on a lifting device 24 by means of brackets 23.
- two extension arms 17 can be spread at the desired angle by means of adjusting spindles 18. They prevent the object from tipping over, the set angle depends on the geometry and the position of the center of gravity of the object.
- FIG. 2 shows a device according to the invention analogous to FIG. 1 without an object to be tilted and not yet fully assembled.
- One end of the pull rod 28 is not yet connected to the axis of the wheels 31 of the lifting device 24. This is shown more precisely than in FIG. 1:
- a carriage 27 slides in a guide of the lifting device and is moved by means of a winch 28 and a rope 29.
- the cable is deflected at the upper end 30 of the lifting device and also runs back from the carriage to the end 30, so that a pulley-type translation is achieved.
- the lifting device is provided with a shoe 32 during assembly, which is removed after the lifting device 24 has been connected to at least one pull rod 28, in order to be able to stand freely during assembly, and has wheels 31 on it Axis, the tie rods 28 are fastened in order to be able to follow the object to be tilted in the course of their actuation, as can be seen from FIG. 1.
- the wheels 31 make it possible for the entire, fully assembled device to be moved like a sliding chest by a single person, who only has to grasp and lift the extension arms 17.
- a stiffened support frame 15 (FIG. 5) is fastened, for example with secured bolts 16, which can also be attached in the same way to the lifting side of the tensioning frame 5, so that the tilting device can be used equally from both sides .
- this overturn protection consists of a device, which can be set for the required support height, for example with two spindles with crank 18, to which, for example, a shock absorber is attached, on which a marking, for example a color marking 19, indicates the state of equilibrium:
- the overturn protection prevents the risk of the workpiece or vehicle tipping over.
- the load of the lifting device still present can be read in any tilt angle position during the lifting process, so that the support height on the tilting side, for example with the crank the spindle 18, be set in good time as a precaution and thus the risk of overturning can be eliminated with certainty.
- the ground rests with pull rods 28 which are articulated and whose length can be adjusted to the track width of the vehicles to be machined or other workpieces the clamping frame part 4 or, depending on the working side, connected to the clamping frame part 5 with a secured bolt.
- the tie rods 28 are provided with the same number of holes at the same distance as on the tenter frame 4, 5 for adjustment to the track width and are fastened with secured bolts, which are preferably located in the middle of the set track width on the tenter frame 4, 5, so that the lifting device 24 is essentially vertical so far during the lifting process, from the smallest to the largest angle of inclination of the tilted clamping frame that the workpiece or vehicle in the clamping frame cannot be touched by the lifting column or lifting device 24.
- a preferred embodiment of the invention is characterized in that both ends of the tensioning frame 4, 5 are designed to fasten the support frame 15 and the lifting device 24 and that when the object to be tilted is fastened, both the support frame and the lifting device can be fastened to the tensioning frame. This allows you to tilt the object first in one direction, then in the other, without having to undo the attachment.
- a further embodiment of the invention provides that the lifting device 24 is releasably connected to the stenter and that for safety reasons a support (not shown) is connected to the stenter in its place after the object has been tilted.
- This support is either replaced by the lifting device for tipping back or enables the device to be tipped back by a brake. This means that several clamping frames can be operated alternately with just one lifting device.
