Definitions

  • the subject of the present invention is a suspension device for a maintenance nacelle for facades comprising one or more cables winding or unwinding on a winch supporting the nacelle and connected to a support, means for monitoring the descent speed of the nacelle and winch blocking means connected to the monitoring means so that they can cause the forced blocking of the winch.
  • suspension devices of this kind are already known. In some cases, they include two or more pulleys between which the cable describes an eight or S path. These devices are relatively simple and light, but it is necessary for the cable to be able to be blocked to provide clamps, claws or jaws which are capable of clamping the cable against a locking element. These devices therefore have the great disadvantage of damaging the cable in the long run.
  • Other devices include a drum whose surface has circular grooves and on which the cable reserve is wound. By one of its extremes. mites, the cable is fixed to the drum and the control motor drives the latter in rotation in one direction or the other depending on whether the platform is to be moved up or down.
  • connection between the nacelle and the support is thus produced by a fixed point, to which one end of the cable is attached, so that it is not necessary to provide jaws or members tightening the cable, which avoids the risk of deterioration.
  • these devices are extremely bulky. Indeed, the cable reserve must be deposited in a single layer on the drum, which leads to drums of extremely large dimensions. The large dimensions of the drum complicate the construction of the winch and increase its weight, which can complicate the arrangement of the circulation paths of the support on the top of the facade.
  • US-A-3,776,368 describes a winch which comprises a drum on which the cable can be wound in several layers, the end of the cable being linked to the drum barrel by one of its ends, and to the nacelle or to the support by the other end.
  • a winch of this kind the cable must be wound up in several layers on the drum barrel, the risks of deterioration through wear and lack of reliability are greater than when drums are used which receive only one layer of cable.
  • the object of the present invention is to remedy these various drawbacks by producing a suspension device of the kind mentioned above which is of compact dimensions, which can be installed both in the nacelle and in the support mounted at the top of the facade. , which allows long cable lengths to be stored without any difficulty and is therefore suitable for installation on very high facades and which is manageable while being absolutely safe to operate.
  • the invention makes use of the properties of winches formed by one or more pairs of pulleys with multiple grooves on which a winding of several turns of son makes it possible to considerably increase the transmission of force between the stretched strand and the strand soft.
  • the presence of deep grooves ensures the connection of the cable with respect to the pulleys by simple friction effect, without jamming or tightening, or risk of deterioration of the cable.
  • the device is characterized in that the winch is formed by one or more pairs of pulleys with grooves of parallel axes, in that a motor is coupled to the winch. so as to rotate all the pulleys in the same direction, each cable being wound several times on one of the pairs of pulleys and having on one side a stretched strand going to the nacelle or to the support and on the other side a soft strand, in that means are provided for keeping the soft strand under tension and in that said monitoring means are arranged so as to be sensitive to the tension of the soft strand and to actuate the winch locking means if this tension drops further below a pre-determined threshold.
  • capstan made up of pairs of grooved pulleys makes it possible to connect each cable to the motor drive axis in such a way that no slippage is possible as long as a minimum tensile force is exerted on the soft strand.
  • this tractive effort is always present both in the direction of ascent and in the direction of descent.
  • the device which will be described may also, like the devices already known, be equipped with means ensuring the safety of persons installed in the nacelle in all circumstances.
  • the suspension device shown in fig. 1 is provided for four cables, two of which are carrying cables for the nacelle and the other two are safety cables.
  • the device can be placed either in the support located at the top of the facade, or in the nacelle itself.
  • the support and the nacelle have not been shown in the drawings.
  • These organs are already known per se. It is known that, in general, the support comprises a carriage mounted either on tire wheels or on rails so as to be able to move along the top of the facade. It generally comprises two tilting arms provided with pulleys which conduct the cables. When the basket is fully raised, the tilting arms can be brought back so as to place the basket on the roof of the building.
  • the suspension device comprises coils on which the cables are wound up as the nacelle rises. It should be noted, however, that in other embodiments, the cables could very well pass through the entire suspension device and then continue in the form of a soft strand facing the facade. Devices of this kind would then be executed with the winch mounted in the nacelle, which would therefore move along the cable up or down without the unwound length of the latter varying.
  • FIG. 1 The general arrangement of the device is visible in FIG. 1.
  • the other coils 1a, 1b, 1c, 1 are mounted on a common shaft 2.
  • Each of the cables a, b, c and d starts from one of the coils to which it is fixed by means which will be described later , passes on a cutting pulley 3a, 3b, 3c, 3d, then on a pair of pulleys 4a, 5a, 4b, 5b, etc., then on two successive references 6a, 7a, 6b, 7b, etc. and then goes to the basket.
  • the pulleys 4a, 5a, 4b, 5b, 4c, 5c, 4d, 5d which constitute the winch are mounted on two parallel shafts 8 and 9 which are also arranged parallel to the shaft 2 while the axes of the references 6a, 7a, 6b, 7b, 6c, 7c, 6d, 7d are perpendicular to the axes of the shafts 8 and 9.
  • Each of the shafts 8 and 9 carries at its end a drive wheel 10, 11 engaged with a pinion 12, driven by a motor 13.
  • the drive wheel 10 also drives a reference 14 engaged with a wheel 15 of slightly smaller diameter than the wheels 10 and 11 which, themselves, are of the same diameter.
  • the wheel 15 is connected to the shaft by a one-way coupling 16 which will be described in more detail later, so that when the motor turns in the direction which causes the elevation of the nacelle, the shaft 2 is driven to a speed slightly higher than the shafts 8 and 9.
  • a one-way coupling 16 which will be described in more detail later, so that when the motor turns in the direction which causes the elevation of the nacelle, the shaft 2 is driven to a speed slightly higher than the shafts 8 and 9.
  • each of the cables a, b, c, d is therefore pulled on the corresponding coil with a force which corresponds to the friction torque.
  • the motor 13 is driven in the opposite direction to that which causes the rise and another one-way coupling 17 between the frame of the device and the shaft 2 prevents rotation of the shaft while the wheel 15 turns freely around this tree.
  • the unwinding of the cables a, b, c, d takes place under the effect of the traction movement which is imparted to the soft strand of the cable by the pairs of pulleys 4a, 5a, 4b, 5b, etc. Indeed, the coils 1 a, 1b, 1 c, 1 d are forced by the traction exerted on the cable to rotate relative to the shaft 2 which is stationary, the resisting torque being given by the force of the friction couplings.
  • the frame generally designated by 18, is a construction in welded sections or formed from an assembly of molded parts.
  • On a frame 19 are fixed end elements 20 which carry bearings of the shafts 8, 9 and 2 respectively supporting the pulleys 5, 4 and the coils 1.
  • the references 6 and 7 are mounted directly on the frame 19.
  • On see in fig. 2 the two references 6c and 6b with cables b and c.
  • the motor 13 is here arranged with its vertical shaft. This motor is equipped with a first worm wheel and worm gear rigidly coupled to the pinion 12 which drives with a reduction of the order of 1 to 6 the wheels 10 and 11 keyed onto the shafts 8 and 9. This is how that a reduction from 1 to 60 is easily achieved between the motor shaft 13 and the shafts 8 and 9.
  • the cutting device 21 which ensures the regular deposition of each of the cables on the corresponding coil.
  • This device 21 comprises the pulley 3 mounted idly on a shaft 22 and a rigid arm 23 which comprises at its end a half-casing 24 itself carrying the shaft 22 and enclosing the pulley 3.
  • the arm 23 is connected to the frame 18 by a double articulation; a lateral tab 23a rigidly fixed to the arm 23, is supported on a rolling track 25 secured to the frame 18 by two rollers with rounded profile 23b.
  • the cable is guided between two rollers 26 and 27 (see also fig. 4) which rotate on parallel axes integral, via the console 28, with the arm 23.
  • this console 28 is articulated around an axis 29 on a rod 30.
  • the latter slides in a bearing 31, integral with the frame 18 and, between its rear end and the bearing31, is housed a coil spring (not shown) which constantly acts on the rear end of the rod 30 and tends to move the joint 29 to the left in FIG. 2.
  • the front end of the rod 30 is equipped with a finger 32 which extends immediately opposite a contact switch 33, also integral with the frame 18.
  • the cable passes through the tubular part of the arm 23 and goes from the cutting pulley 3 to the first pulley 4 of the winch. During its movement, it alternately rotates the arm 23 around the axis of the rod 30, which automatically leads to the deposition of regular layers of cable on the drum of the coil 1.
  • the coil spring housed between the elements 30 and 31 is kept slightly compressed, so that the finger 32 does not press the switch 33. If, on the other hand, for one reason or another, the tension on the part of the cable passing through the arm 23 comes to decrease below a predetermined threshold , the force of the spring becomes preponderant, so that the rod 30 moves to the left in FIG. 2 and that the finger 32 actuates the switch 33. At this moment, the arm 23 pivots around the support of the rollers 23b on the rolling track 25.
  • the cutting device 21 constituted by the pulley 3 and the arm 23 which ensures the regular deposition of the layers of cables on the drum of the coils 1.
  • This device, and more particularly the articulation described above around of the axis 30 ensures the regular deposition of the layers.
  • FIG. 3 shows the four coils 1a, 1b, 1c, 1d.
  • the two outer coils 1a and 1d are used to receive the two supporting cables proper, while the two coils 1b and 1c receive the safety cables.
  • the shaft 2 is connected to the drive pinion 15 and the manner in which it is supported in bearings and coupled to this pinion will be described later.
  • the shaft 2 has bulges 2a and 2b, on which are grooves.
  • the coils 1a, 1b, 1c and 1d are mounted on the shaft 2 by means of ball bearings 37 at the rate of two bearings per coil and by means of hubs 38, 39, and 40. Each coil is supported by two bearings 37 on two hub elements.
  • the inner raceways of the bearings 37 are mounted on hub elements 39, with an L-profile, which have in their inner bore ribs engaged in the grooves between the grooves of the bulges 2a and 2b. Therefore, the hub elements 39, although movable longitudinally on the bulges 2a and 2b, are nevertheless rigidly coupled to the shaft 2.
  • the hub elements 39 are mounted on the bulge 2a, while the remaining hub element 39 is mounted on the bulge 2b.
  • the two outer coils 1a and 1d only one of the hub elements between one of the couplings and the shaft is a type 39 hub element engaged on a bulge 2a or 2b.
  • the other hub element used to support each of the two outer coils is a piece of smooth tubular shape.
  • the hub element 40 which supports the end of the coil 1d is engaged on an enlarged part of the shaft 2 and abuts against a stop ring 41 engaged in a groove of this shaft. It is this stop ring which determines the axial position of the assembly of the coils on the shaft 2.
  • the hub element 38 which is located at the left end of the shaft 2, it also slides on a part of the shaft 2, the diameter of which is reduced to a value less than the bottom of the grooves in the bulges 2a and 2b in order to allow the engagement of the coils from the left end of the shaft 2.
  • This hub element 38 has a housing 38a at its left end and it is in this housing that the spring 42 rests on which acts the bush 43 screwed onto the thread 2c formed at the left end of the shaft 2.
  • This bushing 43 engages in the inner raceway of the bearing44 which supports the shaft at its left end and which is fixed to the left wall 20 of the frame 18.
  • An intermediate ring 45 limits its movement to the right, while a lock nut 46 makes it possible to block it when it has been fully screwed.
  • each hub element 39 with L-profile each have a front face 39a perpendicular to the axis of the shaft 2.
  • This face 39a is in contact with an anti-friction coating 47a which has a intermediate ring 47, integral with a coil.
  • each coil 1a, 1b, 1c, 1d cooperates with a friction device which comprises a ring 47, coated on its two faces with an anti-friction coating 47a.

  • each of the intermediate rings 47 is rigidly coupled to one of the coils 1a, 1b, 1c or 1d. It can be understood that the coils 1 a, 1 b, 1 c or 1 d are coupled to the shaft 2 by the frictions formed between the hub elements 39 or the ring 48 and the intermediate rings 47.
  • the friction torque can be adjusted in a unitary and equal manner for the four coils by means of the sleeve 43 which is screwed onto the end of the shaft 2.
  • the spring 42 may be a coil spring or an element made of reinforced rubber discs or metal frustoconical rings. This element must make it possible to precisely adjust the friction torque in each of the couplings between the shaft 2 and the coils.
  • the drive ratios will be chosen in such a way that the peripheral speed on the barrel of the reels 1a-1d is slightly higher than the peripheral speed of the grooved pulleys 4 and 5.
  • This coupling by example with rollers of a type known per se, is mounted on the tubular sleeve 57 inside the left end of the bearing body 59. It allows the rotation of the shaft 2 only in the direction of elevation of the nacelle and blocks its movement as soon as a rotation begins in the opposite direction.
  • the tubular sleeve 57 centers and guides the drive wheel 15 which is connected to the shaft 2 via the unidirec coupling tional 16 and two support rings 62 and 63, serving as a guide.
  • the wheel 15 can rotate freely relative to the support rings 62 and 63 in the direction in which the shaft 2 is locked, while during a rotation in the other direction, the wheel 15 drives, thanks to the coupling 61, the tubular sleeve 57 and the shaft 2.

  • the movements of the nacelle and its suspension are ensured in a perfectly reliable manner and without risk of deterioration of the cable thanks to the effect of multiplication of the forces carried out by the pairs of pulleys 4 and 5 with their deep grooves in which the cable is tightly guided.
  • the effort required on the soft strand is ensured by friction.
  • a safety locking device shown diagrammatically at 70 in FIG. 1.
  • This safety blocking device comprises a shoe mounted on shock absorbers, cooperating with rollers which come into the braking position under the effect of centrifugal force, if the speed of the shafts 8 and 9 increases beyond a limit value.
  • the brake 70 is connected to a safety switch 71 which also interrupts the flow of current to the motor 13.
  • the suspension device described has all the advantages set out above. Thanks to the capstan made up of pairs of grooved pulleys 4, 5, each cable is connected to the drive axis of the motor 13 in such a way that no slipping is possible provided that a minimum tensile force is exerted on the soft strand. However, this tensile force exists permanently since the soft strands pass, on the one hand, over the cutting pulleys, and on the other hand, arrive on the coils which are driven by friction couplings on the shaft 2.
  • this shaft 2 In the direction of ascent, this shaft 2 is driven at a speed such that the peripheral speed at the barrel of the coils is greater than the speed of driving the cable while, during the descent, the shaft 2 is blocked by the 'free wheel coupling, so that it is the cables which pull on the coils to drive them in rotation and therefore, the tensile force exerted on the soft strand depends directly on the friction couplings.
