Definitions

  • the invention relates to self-elevating platforms or cabins used for the construction, renovation and exterior maintenance of buildings of significant height (typically several tens of meters in height).
  • platform here also means elevation machines, in particular modular machines, which also includes passenger elevators.
  • building is meant here residential or administrative or industrial constructions, etc., but also, by extension, other structures in which self-elevating platforms may be necessary, for example ships in dry dock for construction, maintenance or repair.
  • the object of the invention is to propose improvements to the structures of existing jack-up platforms, in order to bring there improvements in particular in terms of safety, solidity, and ease of use.
  • a self-lifting platform structure which comprises two vertical masts spaced from each other, each provided with a rack, with a movable carriage mounted on each mast and sliding along this mast, each carriage carrying a motor respective cooperating with the rack, and a platform integral with the two carriages, mounted on each carriage, is provided an auxiliary toothed pinion which cooperates with the rack and which is rotated when the carriage moves, a transmission shaft extending between the two masts and which connects the auxiliary toothed pinions of the two carriages so that they rotate in synchronism, characterized in that each carriage includes a housing for a vertical movable plate which carries the motor and which can move vertically in this housing, with springs between the plate and the housing to allow a damped transmission of the force exerted by the plate on the carriage under the action of the motor cooperating with the rack, and in that at least one detector is provided in each carriage for detecting the compression of the transmission springs, this detector being connected to a control of the two motors
  • FIG 1 to understand the context of the invention, there is shown a general view of a lifting structure of a self-elevating platform with two masts, placed along the facade of a building under construction or in renovation.
  • This structure makes it possible to mount a work platform along this facade at any desired height, as and when required.
  • the working platform is designated by the reference 10. It extends between two masts 12 and 14 and even partly cantilevered beyond the masts.
  • the platform is of course fitted with all the safety barriers necessary to protect the people working on the platform and those below it (protection against falling objects).
  • the masts are supported at their base on the ground, in principle by means of supports, 16 and 18 respectively, in the form of plates kept horizontal by adjustable jacks 20 resting on the ground.
  • the masts are fixed from place to place (for example every 5 meters) to the facade of the building, by anchors 22 strong enough to withstand the tensile and torsional forces exerted on the masts by the weight and the movements of the platform 10.
  • the movement of the platform is ensured by electric motors carried by the platform itself, motors which cooperate with rack and pinion carried by the masts.
  • a rack 28 is visible on the right mast 14. That of the mast 12 is not shown in FIG. 1.
  • Each carriage carries at least one electric motor coupled to a reduction gear, with at least one toothed pinion cooperating with the corresponding rack to ensure, during the rotation of the motor, movement of the carriage.
  • the motors are connected by electric power cables 30 to a power source 32.
  • the motor control is preferably located on the platform, so that the occupants can maneuver it themselves; but it is also possible to provide a command from below or a double command, both from below and by the occupants.
  • Figure 2 shows cooperation of an engine and rack.
  • the gear pinion output from the reducer designated by the reference 40, has teeth 42 which mesh with the teeth 44 of the rack 28; the teeth 44 of the rack are machined in a first face of a metal bar which is welded or bolted all along the hoist mast.
  • a pressing roller 48 comes to bear against an opposite face 46 of this bar to keep the teeth of the pinion 40 nested in the teeth of the rack.
  • roller 48 and the pinion 40 are both rotatably mounted on a common metal plate 50.
  • the motor and the reduction gear (not visible because placed behind the plate) are fixed on the plate 50. There is no no play or practically no play between the roller 48 and the pinion 40 so that there is no risk of disengagement of the gear.
  • the plate 50 will therefore be the main drive member of the platform on the hoist mast.
  • the arrangement is identical on the two masts.
  • this plate 50 is not directly integral with the carriage (or drive unit) 24 or 26 of FIG. 1.
  • the structure which makes it possible to drive the carriage 26 from the plate 50 is shown in FIG. 3 Unlike Figure 2 which is a horizontal view, the view of Figure 3 is a top view.
  • the carriage 26, which is integral with the platform 10, comprises for example metal plates 52 or a profile constituting its main framework.
  • the platform is secured by any conventional means (welding, bolts, rivets, etc.) to this frame.
  • the rack 28 is welded or bolted to the mast 14 whose framework is also seen in Figure 3.
  • a housing 54 has been provided for the drive plate 50, housing in which the latter can slide vertically over a certain distance (a few centimeters or tens of centimeters at most) and horizontally (of the order of a centimeter ).
  • the housing 54 is defined for example by metal plates or profiles 56 welded or bolted to the frame 52 of the carriage.
  • the pressure roller 48 is also rigidly fixed to the plate in a position such that it comes to bear against the non-toothed face of the rack. This roller turns freely around an axis which crosses the plate.
  • the motor drives a first toothed pinion 41 which is not coupled to the rack, this first pinion driving two identical satellite pinions 43 and 45 rotating in the same way; the latter are coupled to the rack and two pressure rollers 47 and 49 are placed on the other side of the rack, opposite the pinions 43 and 45 respectively.
  • the transmission of effort is better distributed.
  • the radial force exerted on the gear motor is eliminated.
  • the invention with floating plate and double satellite pinion, aims to distribute the force equally on the two pinions.
  • the torques generated at the level of the guide carriages are much greater than those generated by the recoil or the advancement of the teeth meshing in the rack.
  • the force transmitted between a satellite pinion and the rack varies from zero to 100% depending on whether this pinion is more buried than the other or at the junction of two racks, the pitch changes. In this case one of the pinions works more than the other.
  • the pinions are automatically adjusted by entering or leaving more or less the rack, as the boogies distribute the effort equally (50% -50%) on two rollers or wheels.
  • FIG. 5 represents a horizontal view, perpendicular to the plate 50, showing the plate in its housing 54, and especially showing the connection by springs between the plate and this housing.
  • horizontal walls 60 close the upper part of the housing 54; springs, for example two springs 62 and 64, are placed between the plate 50 and these walls upper horizontal.
  • the plate can exert an action on the walls 60 and more generally on the carriage 26 or the platform 10 only by means of these movement transmission springs. The transmission is therefore damped and there is no shock when the engines are started.
  • the springs can be replaced by silent blocks or even gas shock absorbers.
  • the plate is separated from the lower horizontal walls 66 of the housing 54 by means of springs 68 and 70.
  • the plate can slide vertically in its housing, but it must then exert a compressive force on the springs.
  • the state of compression of the springs can be measured either by deformation detectors, such as strain gauges, or by detectors of displacement of the plate relative to the housing.
  • deformation detectors such as strain gauges
  • detectors of displacement of the plate relative to the housing Such detectors are provided, and are designated by the reference 72. They serve according to the invention to provide security. They can be simple so-called limit switches, but are preferably strain gauges.
  • twin mast machines either with independent motors not linked by a synchronization order, or with central motors, the movement is distributed symmetrically. But in the first case, it is not possible to guarantee mechanical synchronization between the two motor elements (synchronization does not offer any guarantee in the event of failure of the latter or in the event of manual descent intervention with no electricity).
  • the invention makes it possible to remedy all known risks of damage.
  • the detectors 72 can precisely serve to detect an exaggerated compression of the springs, sign of an exaggerated resistance opposed by the platform to the movement that one seeks to impart to it.
  • the springs allow in any case to start and stop smoothly: they dampen the acceleration of the engine.
  • the platform continues to rise on one side only, the other being stopped or even tending to descend.
  • the effort exerted on the rising side will be much greater; the detector 72 can be used to urgently interrupt the supply of the engine which continues to run.
  • the platform cannot start. You have to either unload a part, or better distribute the load to be able to start. It should be noted that an audible and / or luminous alarm can be provided to warn of an overload, even when static.
  • each geared motor being calculated to hold the total load, and the synchronization shaft being calculated to also transmit all the load, the platform is stopped instantly and only a manual descent is possible to descend and remedy the damage safely.
  • the motors are provided with centrifugal brakes which limit the descent speed of the platform to an acceptable value. It is also possible to provide automatic blocking systems released in the event of a power outage, for example cam cleats, self-locking cams, brake pads. integral with the carriage and applied strongly against the rack to slow down the descent.
  • the invention is particularly advantageous in combination with eddy current brakes (comprising a metal disc, generally of copper, rotating in the air gap of a magnet).
  • eddy current brakes comprising a metal disc, generally of copper, rotating in the air gap of a magnet.
  • These brakes can be mounted either on the motor pinion or on the synchronization shaft itself.
  • Figures 16 and 17 show such a device where a motor 58 has at the end of the shaft a metal disc 145 rotating in the air gap of a magnet 146.
  • an electric actuator 147 moves the permanent magnet away from the copper disc and then, after checking by a position contact, the motor starts.
  • the permanent magnet is replaced by the push of a spring 148.
  • the descent is regulated by the electromotive forces generated in the copper disc secured to the motor shaft.
  • an auxiliary pinion is provided, carried by the carriage, cooperating with the rack. But under normal operating conditions, this pinion does not drive the carriage. On the contrary, it is rotated by the movement of the carriage. Climbing, the carriage moves relative to the rack, and this movement therefore rotates the auxiliary pinion.
  • the auxiliary pinion 80 is mounted on a second plate 90.
  • This plate 90 is preferably secured to the carriage. But it can be similar to the plate 50, sliding in a housing 94 similar to the housing 54, this housing being integral with the carriage. damping springs are also provided between the plate 90 and the housing 94. In this case, its condition is also monitored by a detector 72 bis of the same type as the detector 72.
  • the auxiliary pinion and its roller are mounted on the same plate 50 as the main drive pinion if it is possible from the point of view of space.
  • the plate 90 carrying the auxiliary pinion is not necessarily mounted in a floating manner (that is to say by means of springs) like the plate 50. It is moreover possible while the auxiliary pinion is directly mounted on the carriage and not on a movable plate.
  • auxiliary pinion 80 is directly coupled to a drive shaft which extends between the two masts 12 and 14 and which is connected on the other side to the corresponding auxiliary pinion.
  • the two auxiliary gears are therefore directly coupled in rotation.
  • the references are the same as in the previous figures for the mast 14.
  • the references are the same with the index "prime"; thus, the rack for the mast 12 is designated by 28 '.
  • the carriages 26 and 24 are not shown; but they are connected to the auxiliary plates 90 and 90 'by springs, as has been explained.
  • the transmission shaft which can also be called synchronization shaft, is designated by 100. It extends over the entire length separating the masts 12 and 14 in FIG. 1.
  • auxiliary pinions rotate in synchronism, each driven by the movement of the corresponding carriage, since the two motors operate and rotate at the same speed.
  • the platform rises or falls horizontally.
  • parachute brake can also be mounted directly on the shaft 100 (in case the two motors are down).
  • the spring compression detectors 72 will be able to quickly detect an excessive compression threshold and control the interruption of the current in the overloaded motor or in the two motors.
  • the detectors can be simple limit switches. They indeed detect the state of compression of the springs either directly (they are then for example strain gauges) or indirectly, for example by detection of the position of the plate 50 in its housing 54.
  • Another safety problem resolved here is the risk caused by the mismatch between the position of the jack-up platform and the facade of the building at the places where a passage must be provided between the platform and the building.
  • the platform which is normally surrounded by protective barriers against falling people or objects, then has a passage opening facing the building.
  • the building is also provided with a protective barrier which can be opened at the access point, in the same way as a modern elevator door: the door is integral with the building in which one accesses, even if there is also a door in the mobile part of the lift.
  • a problem which results from this arrangement in the case of self-elevating platforms is the fact that the flexibility of the hoist mast (s) can make appear an interval between the facade of the building and the platform; this interval can be several tens of centimeters; it is dangerous, in particular by the risk of falling objects that it can cause.
  • a fixed door unit placed at the location of the access opening in the building, be mounted integral with the mast or masts, and not integral with the building.
  • This structure is particularly advantageous in the case of constructions with two masts, the door unit being fixed on a cross member secured to the two masts. Since the platform is integral with the masts, and the fixed door unit is also integral with the masts, there is no significant risk of play between the two.
  • Figure 8 and Figure 9 show, respectively in side view and in top view, the corresponding construction.
  • the masts are designated by the references 12 and 14, the platform by 10, the facade by 110 and the access window by 112; the structure of the fixed door unit, designated by 113, comprises a frame 114 integral with the two masts and therefore extending horizontally between them, and a horizontal plate 116.
  • This plate extends from the platform 10 (when it is at the correct height) to the interior of the building through the window 112.
  • the clearance between the platform 10 and the plate 116 can be very reduced (a few centimeters at most).
  • the tray 116 is surrounded by protective barriers 118, and passage doors 120 are provided on the door block; doors 122 are in principle also provided on the platform 10.
  • This arrangement is particularly advantageous for structures with two masts where there is space to place a door between the masts and the facade (in the interval between the masts)
  • a door block is proposed at the very bottom (for access to the platform at ground level), this door block being fixed to the mast and being movable in height along this mast.
  • the door unit is mounted in the same way as the platform on a carriage driven by a motor cooperating with the rack of the mast.
  • the assembly can be the same as described previously; however, it is simpler to provide a direct drive (without transmission springs) between the engine and the rack.
  • Figures 10 and 11 show this construction, applied to a lifting platform structure with a single mast to simplify the representation.
  • the door block 120 placed at the bottom of the mast is integral with the mast; it comprises lateral protective barriers 122, an access door 124, a lower plate 126, and possibly an external access ramp 128 protruding outside the barriers 122.
  • the lower door unit can include a drive motor 130 (but it is also possible to use manual lifting means such as a crank and a sufficiently multiplied gear system).
  • the motor or the gear system cooperates with the rack 28 to ensure the positioning of the entire block at a desired height.
  • the structure can be easily transported over a short distance without dismantling it (for example a movement along a building facade).
  • Rolling carriages are placed under the platform, for example one at each end, and the platform is lowered along the masts until it rests on the carriages. At the end of the descent, the platform rests on the rolling carts.
  • the lifting motors of the platform are then actuated, in a direction tending to lower it along the masts.
  • the masts rise slightly.
  • the carriages can then be rolled without having to dismantle the masts.
  • one of the important advantages of the invention is the possibility of working suspended on a facade, or as on the side of a ship for example ( Figure 14).
  • the masts are mounted, but with only one anchor point at the top of the mast.
  • This is possible with a twin-mast structure, whereas this would not be possible, given the torsional forces, with a single-mast structure.
  • platforms of great length because they are more resistant because they do not have a greatly reduced width at the location of the masts, unlike the usual platforms which are indented for the passage in front of the anchors. This possibility is not reserved for flared facades.
  • FIG. 12 shows the use of such a structure with attachment only at the top of the masts.
  • the single anchor point of the mast 12 on the facade 110 is designated by the reference 140 in FIG. 12. It can be seen in FIG. 13 that the platform 10 has only two openings with closed outline for the passage of the masts 12 and 14, but no notches (openings with open outline) for the passage of the platform at the level of anchoring points.
  • the airlock door comprises a door bottom 141 and a roof 142 which are two long plates opening by tilting around horizontal axes. Once tilted, they release the opening of leaves 143 and 144 of the cabin door. These leaves 143 and 144 are preferably of the deployable type like the wings of a fabric fan. When the leaves are folded over each other, the airlock door is extended: these leaves prevent operators from tipping sideways into the void. When folded, the platform is closed. Plate 141 is approximately 50 cm wide.
