Abstract
Description
- The subject of the present invention is a lift platform, which comprises a working plane, a base, and at least one scissor-like articulation mechanism which connects the working plane and the base with each other, the working plane being arranged displaceable substantially vertically relative the base by means of the said articulation mechanism and at least one hydraulic lifting cylinder connected to same and also tiltabie longitudinally relative to the base.
- A lift platform in which a particular scissor-like articulation mechanism is used so as to displace the working plane vertically relative the base is known in prior art. Ordinarily, such an articulation mechanism comprises beams articulated with each other crosswise in the way of scissors, the lifting force being imparted to the said beams by means of a hydraulic cylinder placed between the articulation point and the base. At one of their ends, the beams are attached to the working plane and to the base conventionally by means of an articulated joint, but at the opposite ends the beams are, as a rule, mounted mowably on a horizontal guide in order that a movement of the mechanism should be possible.
- Working .planes of the type described above are known in prior art, e.g., from the U.S. Patent No. 3 863 793 and from the GB Patent No. 1 354 962. In the said U.S. publication, a device of transportation and installation of ceiling supports for use in mines is described, wherein the lifting mechanism consists of a scissor-like articulation mechanism of the sort described above and of a hydraulic cylinder. The "working plane" of this device is, however, not provided with separate means of tilting, nor can the articulation mechanism as a whole be tilted. The GB Patent No. 1 354 962 describes a cargo handling device used for the loading of aeroplanes, which said device comprises two separate lift platforms provided with scissor-like articulation mechanisms. The said lift platforms are, however, of conventional construction, and none of them is provided with a possibility of tilting. If the above devices of prior-art technology were to be provided with a possibility of tilting, the construction of the devices would have to be modified considerably and, in order to permit tilting of the working plane, the devices would have to be provided with a separate tilting mechanism. This would make the said lift platforms highly complicated and inconvenient in operation.
- A lift platform according to the preamble of
claim 1 is shown in DE-A-2 224 713, in which the working plane is tiltable (in only one direction) relative to the scissor mechanism, and in CH-B-489 383 and DK-B-141 864, in each of which the scissor mechanism has sliding joints allowing the working plane to tilt (again in only one direction). - In view of eliminating the drawbacks related to the prior-art solutions, the object of the present invention is to provide a lift platform whose working plane is arranged tiltable in two directions. In view of achieving the objectives stated above and those that will come out in the following, the present invention is characterised in that a first pair of articulated arms of the crosswise pairs of articulated arms of the single or lowermost scissor-like articulation mechanism are attached to the base by a tilting mechanism, by means of which the working plane is tiltable longitudinally relative to the base in both longitudinal directions by tilting the whole scissor-like articulation mechanism.
- As compared with the prior-art solution, several advantages are obtained by means of the invention, of which, e.g., the following should be stated. The working plane of the platform in accordance with the invention is arranged tiltable in two directions without a complicated tilting mechanism provided for the working plane. In the solution of the present invention, the entire articulation mechanism of the lift platform is tilted, owing to which a better stability is obtained by means of the device when the base of the lift platform is in a position inclined from the horizontal plane. It is quite a remarkable advantage that tilting of the working plane is possible within the whole range of operation and not only with the working plane raised.
- The invention will be described in more detail in the following with reference to the figures in the accompanying drawing.
- Figure 1 shows a lift platform in accordance with the invention in its lower position.
- Figures 2 and 3 are schematical sectional views of a lift platform in accordance with the invention in the upper position and inclined in different directions.
- The main parts of the lift platform in accordance with Figures 1 to 3 are the
working plane 1, thebase 2, the scissor-like articulated mechanism 3, and thetilting mechanism 4. - In the embodiment shown in the figures, a vehicle frame is used as the
base 2, but as a base, it is also possible to use, e.g., a separate auxiliary frame attached to the vehicle frame, a displaceable base provided with wheels or equivalent, or also a stationary, non-mobile base. As to its construction, the scissor-like articulation mechanism 3 is quite a conventional scissor-like articulation mechanism, and it comprises a first pair of articulatedarms 31 and a second pair of articulatedarms 32, which are articulated with each other crosswise by means of a first articulatedjoint 33 placed at the middle of the said articulatedarms arms 31 are linked by their lower ends to thetilting mechanism 4 by means of a third articulatedjoint 35, and at the upper end of each first articulated arm 31 afirst slide member 12 is mounted, which is fitted so as to run in afirst guide 11 provided on theworking plane 1. - Correspondingly, each second articulated
arm 32 is by its upper end linked to the working plane by means of a second articulatedjoint 34, and the lower ends of the second articulatedarms 32 are provided withsecond slide members 22, which are fitted so as to run in horizontalsecond guides 21 mounted on the base. The saidslide members guides several lifting cylinders 36, whose bottom end is attached by means of an articulated joint, either directly or by the intermediate of fastening members, to the first articulatedarms 31 within the area between the said first articulatedjoint 33 and the third articulatedjoint 35, and which said liftingcylinders 36 are, by the upper end, i.e. by the piston rod, attached by means of an articulated joint, either directly or by the intermediate of fastening members, to the second articulatedarms 32 within the area between the said first articulatedjoint 33 and the second articulatedjoint 34. As thelifting cylinders 36, it is possible to use single-acting or double-acting hydraulic cylinders, and in the embodiment shown in the figures, thelifting cylinders 36 consist of telescopic cylinders, which provide large lifting height and require little space in the compressed state. - In the embodiment shown in Figs. 1 to 3, it is shown further that there is only one scissor-like articulation mechanism 3 between the
working plane 1 and thebase 2. It is, however, obvious that in the device it is possible to use several scissor-like articulation mechanisms 3 placed one above the other, linked together in a way in itself known. In such a case, the topmost scissor-like articulation mechanism 3 is attached to theworking plane 1 in the way described above, and the lowermost scissor-like articulation mechanism 3 is attached to thebase 2 and to thetilting mechanism 4 in the way described above. - The tiltability of the lift platform has been achieved by means of the
tilting mechanism 4, which comprises tiltingarms 41, which are by one end attached to thebase 2 by means of a fourth articulatedjoint 42 and which said tiftingarms 41 are, by the opposite end, attached to the first articulatedarms 31 by means of a third articulatedjoint 35. The tiltingarms 41 are arranged pivotable around the said fourth articulatedjoint 42 by means of tiltingcylinders 43, which are by one end attached to thebase 2 by means of an articulated joint and, by the opposite end, i.e. by the piston rod, attached to the tiltingarms 41 by means of an articulated joint. By shortening and extending thetilting cylinders 43, it is thus possible to pivot the tiltingarms 41 around the fourth articulatedjoint 42, whereby the position of the third articulatedjoint 35 relative thebase 2 is changed, which produces a tilting of the entire scissor-like articulated mechanism 3 and theworking plane 1 in the desired direction relative the longitudinal direction of the working plane. - Next, the operation of the lift platform in accordance with the invention will be described in more detail.
- The working
plane 1 is raised or lowered by means of the liftingcylinder 36, which is attached to the first and second articulatedarms cylinder 36 forces the first and second articulatedarms joint 33, whereby thefirst slide members 12 placed at the upper ends of the first articulatedarms 31 glide along thefirst guides 11 provided on theworking plane 1, and correspondingly thesecond slide members 22 placed at the lower ends of the second articulatedarms 32 glide along thesecond guides 21 placed in thebase 2. Depending on the direction of the movement of thelifting cylinders 36, the upper ends of the articulatedarms working plane 1, placed as supported on one of the articulatedjoints 34 and on one of theslide members 22 is raised or lowered. - The working
plane 1 moves in the vertical direction being parallel to the base if the level of the third articulatedjoint 35 relative thebase 2 is adjusted appropriately. In the example shown, the position of the third articulatedjoint 35 relative thebase 2 is correct for keeping theworking plane 1 horizontal, i.e. in the vertical direction the said articulatedjoint 35 is placed at the same level with thesecond slide members 22 when thetilting arm 41 has been positioned by means of the tiltingcylinder 43 parallel to thebase 2, i.e. horizontal. Thetilting mechanism 4 is dimensioned so that, when thetilting arm 41 is horizontal, the piston rod of the tiltingcylinder 43 has been pushed half a stroke out of the cylinder, whereby it is achieved that the tilting allowance of theworking plane 1 is, from the horizontal position, equally large in both directions. - Under these circumstances, the working
plane 1 is inclined by means of thetilting mechanism 4 as follows: The piston rod of the tiltingcylinder 43 displaces thetilting arm 41, whereby a pivoting of the third articulatedjoint 35, which interconnects the tiltingarm 41 and the first articulatedarm 31, around the fourth articulatedjoint 42, the tiltingarm 41 constituting the radius for the said pivoting, produces a pivoting of the entire scissor-like articulated mechanism 3 around thesecond slide member 22, which is placed in theguide 21 and which is connected to the second articulatedarm 32, whereby theworking plane 1 is tilted. - In accordance with the above, it is an essential feature of the solution in accordance with the invention that the working
plane 1 can be tilted in the longitudinal direction in both directions. The workingplane 1 is appropriately arranged so that it can be tilted in the longitudinal direction by 10° relative thebase 2 in both directions. The tilting allowance may, of course, also be larger than ±10°, but in most cases the said tilting allowance of ±10° is sufficient. Moreover, especially in those cases in which several scissor-like articulated mechanisms 3 placed one above the other are used, the stability of the equipment may constitute a problem if the tilting extent is considerably above 10°. The tilting of the workingplane 1 is performed by tilting the entire scissor-like articulated mechanism 3 of the lift platform. Tilting of the workingplane 1 is possible within the whole working range of the lift platform, which has been achieved thereby that thelifting cylinders 36 and the tiltingcylinders 43 have been arranged adjustable separately and independently from each other. - Above, the invention has been described by means of an exemplifying embodiment with reference to the figures in the accompanying drawing. This is, however, not supposed to restrict the invention to the exemplifying embodiment illustrated in the figures only, but many variations are possible within the scope of the inventive idea defined in the following patent claims.
