Definitions
- the invention relates to self-elevating platform structures used for the construction, renovation and exterior maintenance of buildings such as, in particular, residential constructions, administrative or industrial constructions, but also, by extension, such as ships in dry dock or not.
- first and second vertical masts each provided with a rack.
- Gears mounted on mobile motorized carriages mesh with each other in the rack and drive a horizontal platform carried by the carriages, in vertical translation.
- the platform, as well as the personnel and the tools it supports, can be raised or lowered at will, in order to carry out precise work at an adequate height on a building.
- the known platforms extend between the masts and also on either side of them. They are broken down into modular elements which, joined together, form at least three distinct segments: a central segment and two lateral segments.
- the central segment extends only between the masts and the lateral segments extend only on either side thereof.
- the lateral segments and the central segment are connected, at the height of each mast, to the carriages.
- the connections between the segments and the carriages have at least one degree of freedom in rotation of so that a slight inclination of a segment with respect to the horizontal is tolerated.
- the segments are independent of each other and a force applied to one of them may not be transmitted to another segment, but only, in the form of a couple, to the carriage and, more precisely , to the masts by means of guide rollers.
- the rotation of the segments relative to the masts is then used to make a complicated mechanism for blocking the movement of the platform when the inclination becomes too great.
- robots carried by the platform, cannot move from one segment to another, but remain confined to one of them.
- a problem which the invention proposes to solve is to construct a self-elevating structure, which overcomes the abovementioned drawbacks at a lower cost, and in which the transmission of forces at the level of pinions engaged on the rack does not generate torques causing disturbances in the translational movements of the platform.
- the solution to this problem lies in a self-elevating structure in which the platform, which extends between the masts and possibly, on either side thereof, is rigid, and in that the support shafts of said platform have been placed on the carriages perpendicular to the rack, that is to say with axes orthogonal and intersecting with said rack.
- the subject of the invention is a self-elevating platform structure composed:
- the rigidity of the platform, between the masts and on either side of them will allow robots, carried by said platform, to move over the entire length thereof.
- FIG. 1 shows, in front view, a self-elevating platform structure according to the invention
- FIG. 2 shows, in profile view, a self-elevating platform structure according to the invention
- FIG. 3 shows, in front view, the arrangement of the different rollers and pinions of a carriage of a jack-up platform structure according to the invention
- FIG. 4 shows, in top view, a carriage of a jack-up platform structure according to the invention
- FIG. 5 represents, in perspective, a carriage of a self-elevating platform structure according to the invention
- FIG. 6 illustrates, schematically, the distribution of forces applied to a platform of a structure according to the invention
- FIG. 7 illustrates, schematically and exaggerated, an inclination of a carriage of a jack-up platform structure according to the invention
- FIG. 8a, 8b and 8c illustrate, schematically, a blocking of a jack-up platform structure according to the invention
- FIG. 9 and 10 illustrate, in top view and in section, the arrangement of plates of a platform of a structure according to the invention.
- FIG. 11 illustrates, schematically, a self-lifting platform structure according to the invention, in a low position called transport.
- Figures 1 and 2 show a self-elevating platform structure 1 according to the invention, placed in front of a facade 2 of a building under construction or under renovation.
- This structure 1 comprises two vertical masts, a first mast 3 and a second mast 4 separated from each other by a distance, in an example of the order of ten meters.
- These masts 3, 4 are formed of metal uprights 5 connected to one another by oblique or horizontal bars 6. Depending on the number and the position of said uprights 5, the masts 3, 4 have a rectangular, square or triangular section.
- the following description is made with reference to a structure with two masts, but, because of the rigidity of the platform, it will be easy to transpose the teaching of the invention to a structure with more than two masts if the need arises. makes itself felt.
- the masts 3, 4 rest on plates 7, 8 forming supports and kept horizontal by adjustable jacks 9 leaning on a floor 10. They are also advantageously fixed from place to place, for example every five meters, at the facade 2 of the building, by anchors 11 strong enough to withstand the tensile and twisting forces exerted on the structure 1.
- Each mast 3, 4 is provided, over its entire height, with a rack shown in thick lines in Figure 1. There is therefore a first rack 12 on the mast 3 and a second rack 13 on the mast 4. The racks 12 , 13 are welded or bolted to the masts 3, 4, for example to the bars 6. Finally, each mast 3, 4 carries a carriage. There is therefore a first carriage 14 on the mast 3 and a second carriage 15 on the mast 4.
- the carriages 14, 15 support a platform 16 which extends between the masts 3, 4 and on either side thereof, overhanging.
- the platform 16 is made up of elements 17 assembled so as to form a continuous and rigid assembly between the masts 3, 4, and on either side thereof.
- the platform 16 has, at its periphery, safety barriers 18 for the protection of the people therein as well as those who are below, then protected from falling objects.
- the carriages 14, 15 are movable in vertical translation along the masts 3, 4. Also, when the carriages 14, 15 rise, the platform 16 rises, and when the carriages 14, 15 descend, the flat ⁇ form 16 descends.
- motors 19 shown only in FIGS. 3 and 4, carried by the carriages 14, 15 are connected by electric cables 20 to a power source 21.
- the power control for the motors 19 is preferably located on the platform 16 so that the occupants can maneuver it themselves.
- the carriage 15 having a metal plate 22.
- This plate 22 or an arrangement of profiles constituting its main frame, carries, on one of its faces 23 , on the one hand, three gables toothed: two drive pinions 24, 25 and a motor pinion 26. On the other hand, it carries two pressing rollers 27, 28. These pinions 24, 25, 26 and rollers 27, 28 are mounted to rotate on the plate 22 , so that their axes of rotation pass through it, perpendicularly.
- the drive pinion 26 is meshed on the two drive pinions 24, 25 and the latter are themselves meshed on a toothed side 29 of the rack 13 of the mast 4.
- the pinion 26 is thus considered to be meshed on the rack 13 , indirectly.
- the pressing rollers 27, 28 come, for their part, to press on a non-toothed side 30 of the rack 13 opposite its toothed side 29, directly opposite the drive pinions 24, 25.
- the vertical translation of the carriage 15 can be explained as follows.
- the electric motor 19 of the carriage 15 coupled to a reduction gear and carried by an opposite face 31 to the face 23 of the plate 22 drives the motor pinion 26 in rotation. This rotation is reflected in the drive pinions 24, 25 which move on the rack 13, cause the carriage 15 to go up or down, the pressing rollers 27, 28 limiting the lateral exhaust of said pinions
- each carriage 14, 15 comprises an axial support.
- This axial support is formed by a removable metal shaft 32 housed, at one of its freely rotating ends, in a bearing 33.
- the bearing 33 is fixed to the bottom of the plate 22, on the motor side 19. It could nevertheless be fixed on the other side of the plate 22, as long as the shaft 32 does not come into contact with the rack 13.
- the shaft 32 is perpendicular to the rack 13.
- the center of the bearing 33 is located in the plane of the toothed side 29 of the rack 13 which also contains the center G.
- the support shaft 32 is supported, at another end, by another bearing 36.
- the other bearing 36 is fixed by two horizontal bars 34, 35 fixed, in particular by welding, at one of their ends, to the plate 22, and joining, at their other end, on the bearing 36.
- the bearing 36 is pierced with 'a through hole 37 crossed by said support shaft 32.
- the bars 34, 35 therefore define a triangle. Another structure can however be envisaged to hold the bearing 36.
- Each carriage 14, 15 further comprises first and second guide rollers 38, 39 mounted to rotate on the plate 22 according to axes of rotation passing through it perpendicularly.
- These rollers 38, 39 are arranged in the lower part of the plate 22. They are located symmetrically on either side of the support shaft 32 of each carriage 14, 15, horizontally. They press on the vertical uprights 5 of the mast 4.
- the axes of the rollers 38, 39 and those of the shaft 32 are located in the same plane represented by a horizontal axis.
- an element 17a of the platform 16 engages along the shaft 32 so that said element 17a retains a mobility in rotation according to said shaft 32.
- the shafts 32 of the masts 3 and 4 allow an inclination, at least slight, of the platform 16.
- FIG. 8b instead of being an element 17a of the platform 16 which comes to engage along the shaft 32, it is possible to place a box 17b which supports the platform 16.
- the box 17b can be directly secured to the platform 16, for example by welding, or not. If the box 17b is not directly integral with the platform 16, the latter is also supported by the shaft 32 (as in FIG. 8a), and then a clearance between said box 17b and said platform 16 may exist.
- This game gives a certain tolerance of the structure of the invention to the slight inclinations of the platform 16. Its usefulness will be seen below.
- a single force sensor for example a load cell, judiciously placed along each of the two support shafts 32, is sufficient to measure the force F over the entire platform 16.
- a second force sensor is provided, for safety reasons.
- such a sensor is mounted in the bearing 36 or even inside the shaft 32 at the place where this shaft rests in one of the bearings.
- the carriage 15 which comprises only two guide rollers 38, 39 aligned on either side of the support axis, and which, therefore, is not guided or retained in its part upper, pivots along the axis of the shaft 32 so as to follow the inclination of the rack 13.
- the platform 16 nevertheless retains a substantially horizontal position.
- the carriage is of floating plate but there are always only two rollers 38,
- FIGS. 8a and 8b the platform 16 is shown diagrammatically inclined at an angle ⁇ relative to the horizontal.
- ⁇ the angle relative to the horizontal.
- Figure 8a it is the element 17a of the platform 16 engages along the shaft 32-
- Figure 8b the box 17b engages along said shaft 32.
- ⁇ is less than 1%.
- 1 and 2% one acts on the motors 19 so that the inclination is regulated. From 2%, the motors 19 are cut to allow catching up and when ⁇ reaches 3%, the vertical translation is blocked.
- brake stops or brake pads 40, 41 are shown integral with the element 17a of the platform. 16 or box 17b, to which they are welded or bolted.
- they are mounted on brackets which are fixed to the element 17a or 17b. These brackets project horizontally beyond the plane of the plate 22, for example passing under this plate as shown in Figures 8a and 8b.
- the brackets are located near the vertical uprights 5 of the masts 3, 4, so that, when the platform 16 is horizontal, a given clearance separates them from said uprights 5.
- FIG. 8c also shows bearings 33b and 36b, integral with the element 17a or the box 17b and mounted in this so that the shaft 32 can pass through them at the same time as the bearings 33 and 36.
- FIGS 9 and 10 there is shown schematically, in top view and in cross section respectively, the platform 16, produced by the rigid assembly of elements 17.
- These elements 17, of triangular section here and of elongated shape each have, in their upper part, a plate 42 movable transversely. They also include trays 43 which can be folded horizontally. All the trays
- the plates 43 are advantageously movable sliding longitudinally along the edges of the platform
- the platform has a certain modularity which allows it to comply with the dimensional requirements imposed by the buildings. This modularity is notable, given that the platform
- the position of the plates 43 can be arbitrary along said platform 16, the carriages not constituting an obstacle to the mobility of said plates 43.
- these sliding plates can reach the ends cantilever segments.
- FIG. 10 a robot or a crane 48 has been shown diagrammatically.
- This robot 48 is mobile. It is capable of moving over the entire length of the platform 16, for example with a sliding base within retaining rails 49 integral with said platform 16. In fact, the rigidity and the continuity of the platform -form 16, in particular beyond the masts 3, 4, allows such displacements.
- a single robot 48 is sufficient per structure 1 of the invention for loading or unloading or for the transfer of materials to a given location on the platform 16, between the masts 3, 4, or on either side thereof.
- Figure 10 also shows a plate 50, which also slides longitudinally to the platform 16 in rails 49 for holding fixed to the elements 17. The plate 50 makes it possible to approach as close as possible to the facade 2. There is a plate 50 between masts 3 and 4 and one on each side of each mast.
- FIG 11 there is shown the self-supporting platform structure 1 of the invention, in a low position called transport.
- the platform 16 is held in receptacles 47 integral with the plates 7, 8 forming a support.
- the cylinders 9 are adjusted in the high position.
- a set of two wheels 45, 46 of each plates 7, 8 rest on the ground 10.
- the assembly thus described forms an adequate transport chassis.
- the platform 16 being rigid, it suffices only two wheels per tray 7, 8 for the transport of the structure 1 of the invention instead of four for the structures with segmented platform of the prior art .
- the axes of the plate wheels are in line with the masts. For orientation, it is sufficient that only one set of wheels is steerable.
