    Elevator installation and procedure for arranging a driving machine of an elevator installation
    Description
    The present invention relates to an elevator installation and a method for arranging a driving machine for an elevator installation as defined in the claims.
    An elevator installation is known from the JP-50297/1992 industrial utility model in which a drive machine moves a cabin and a counterweight by means of a drive cable and does not need a separate machine room. As a guide for the cabin and the counterweight, two vertical columns in the form of self-supporting U-profiles are used. The columns are closed at its upper end with a horizontal crossbar, on which the drive machine is mounted. Thanks to the suppression of the machine room, this elevator installation has the advantage of lower production costs.
    EP-1045811 shows an elevator installation in which a crossbar that supports the drive machine is fixed to, in total, four guides for the cab and the counterweight. In this way, the entire vertical weight of the drive machine, the cab and the counterweight is driven to the floor of the box and is supported exclusively by these guides, using conventional economic guides. To this is added the additional advantage that the driving machine does not exert bending moments on the supporting guides, since thanks to this arrangement and fixing only vertical forces act on the guides. In this elevator installation the limitation of the arrangement of the driving machine to the lateral area of the box, by which the guides extend, is a disadvantage.
    Document US2002 / 0070080 shows another elevator installation in which a cross member supporting the drive machine is fixed to counterweight guides and a first cabin guide. The drive machine has two drive pulleys, which are arranged at the ends of both sides of the drive machine. This arrangement allows a stable cab suspension.

    The object of the present invention is an elevator installation with a flexible arrangement of the driving machine. The drive machine must be available for free choice in large part of the entire area of the box above the cab and the counterweight. The drive machine must be arranged in a way that saves space and has small dimensions. This is achieved by the invention as indicated in the claims.
    The invention relates to an elevator installation with cabin and counterweight and a box, which has a driving machine mounted on a crossbar. The crossbar is fixed by two terminal zones to two counterweight guides and is fixed by a central zone to at least one cabin guide.
    The two counterweight guides and the cabin guide define an essentially horizontal triangle in the box. The driving machine has an elongated and compact shape. The drive machine advantageously features two drive pulleys, which are symmetrically arranged, to the left and to the right of a horizontal line connecting the car guides.
    By means of this symmetrical triangle arrangement of the guides, the weight of the driving machine and the bending moments that occur during the operation of the driving machine are effectively absorbed and driven to the floor of the box by means of the crossbar and the guides. The driving machine can be arranged freely on the surface of this triangle, either essentially above the counterweight and / or essentially above the cab. This flexibility with respect to the arrangement of the drive machine is made possible by the size and shape of the crossbar and / or the number of deflection pulleys used and / or the type of drive means used.
    The invention will now be explained in detail by means of embodiments shown in Figures 1 to 10, which show:

    exemplary embodiment of the arrangement of a driving machine with
    gear in a 2: 1 suspension according to Figure 9.
    Figure 1 shows a schematic representation of the triangle arrangement of the guides 5, 5 ', 9, 9' of an elevator installation. The elevator installation is arranged for example in a box 10, essentially vertical. The box 10 has, for example, a rectangular cross section with four walls. Cabin guides 5, 5 'and counterweight guides 9, 9,' arranged essentially vertically are fixed in the box. Two cabin guides guide a cabin 11 and two counterweight guides guide a counterweight 12. The guides are fixed to the nearest walls. The two counterweight guides 9, 9 'and a first cabin guide 5 are fixed to a first wall. The second cabin guide 5 'is fixed to a second wall. The second wall is located in front of the first wall. The first cabin guide 5 is arranged essentially centered between the two counterweight guides 9, 9 '. The guides are composed of proven materials such as steel. The fixing of the guides to the walls is done, for example, by screw connections. Knowing the present invention, other box geometries with square, oval or round cross-section can also be made.
    The two counterweight guides 9, 9 'and in each case one of the two cabin guides 5, 5' define in the box 10 an essentially horizontal triangle T. The horizontal line that joins the two counterweight guides constitutes a first side of the triangle T. The horizontal lines that join a counterweight guide and a cabin guide constitute a second side and a third side of the triangle T. The horizontal line that joins the Counterweight guides are advantageously longer than a horizontal line that joins the cabin guides, such that a triangle T formed by the guides 9, 9 ', 5 of the first wall has an obtuse angle opposite the horizontal line joining the counterweight guides 9, 9 ', or in such a way that a triangle T formed by the counterweight guides 9, 9' of the first wall and a cabin guide 5 'of the second wall has an acute angle opposite the line horizontal joining the counterweight guides 9, 9 '. The horizontal line that joins the cabin guides advantageously cuts the horizontal line that joins the counterweight guides essentially in the center, so that the triangle T is essentially isosceles.

    Figures 2 to 10 show a drive machine 1, 2, 3, 3 ', 4, 40 with two drive pulleys 3, 3'. The driving pulleys 3, 3 'are advantageously in active connection with a motor 1 and a brake 2 by means of a shaft 4. The motor and the brake are advantageously arranged in two terminal areas of the shaft and the driving pulleys are arranged between the engine and brake, in a central area of the tree. A control and / or converter of the elevator installation is arranged in a distribution box 6, advantageously in a wall of the box 10. In the embodiments according to Figures 2 to 8, the driving machine lacks gear and has a elongated shape, so that, seen in a plane perpendicular to the axis of the shaft 4, the diameter of the driving machine is smaller than the length of the driving machine. In the embodiment according to Figures 9 and 10, the driving machine is provided with a gear 40. In these embodiments, the driving machine also has an elongated shape, that is, seen in a plane perpendicular to the gear shaft. 40, the diameter of the driving machine is smaller than the length of the driving machine.
    Advantageously, two drive pulleys 3, 3 'are arranged symmetrically, to the left and to the right of a horizontal line joining the cabin guides 5, 5'. The drive pulleys 3, 3 'advantageously have a smaller diameter than the motor housing and / or the brake housing.
    The driving machine, which is arranged in an essentially horizontal position in the box, moves the cabin and the counterweight, which are connected to each other, by means of at least one drive means 19, 19 '. The drive means or means have two ends 18, 18 '. The drive means is a cable and / or a belt of any kind. The areas of the drive means that support the load are composed of metal, for example steel, and / or plastic, for example aramid. The cable can be a single or multiple cable and can also have an outer plastic protective sheath. The belt can be flat and externally smooth and unstructured or, for example, be structured as a trapezoidal belt with internal toothed or a toothed belt. Advantageously, two drive means are used.
    image10
    The ends of the actuating means are each fixed to a wall of the box or a roof of the box and / or a cabin guide and / or a counterweight guide and / or a cross member 8 and / either to the cabin and / or to the counterweight. The ends of the drive means are advantageously fixed by elastic intermediate elements to dampen the structural noise. The intermediate elements are for example spring elements that prevent vibrations, which are unpleasant, from the actuation means being transmitted to the wall of the box / the roof of the box and / or to the cabin guide and / or the guide of counterweight and / or to the crossbar and / or to the cabin and / or to the counterweight. Several examples of embodiments of fasteners of the ends of the drive means are provided:
    -In the embodiment according to Figures 3 and 4, a first end 18 of the actuating means is fixed to the wall of the box / the roof of the box and / or to the cabin guide 5 ', and a second end 18 'of the actuating means is fixed to the wall of the box / the roof of the box and / or to the crossbar 8 and / or to the cabin guide 5.
    -In the embodiments according to Figures 5 and 6 and Figures 9 and 10, one or both ends 18, 18 'of the actuating means are fixed to the wall of the box / the roof of the box and / or the guide cabin and / or crossbar.
    - In the embodiment according to Figures 7 and 8, a first end 18 of the drive means is fixed to the cabin 11 and a second end 18 of the drive means is fixed to the counterweight 12.
    According to said embodiments, two drive pulleys move two drive means by friction by adhesion. Knowing the present invention, the person skilled in the art will also be able to use different driving machines and drive procedures different from those represented in the examples. Thus, the person skilled in the art may use a drive machine with only one or more than two drive pulleys. The technician can also
    image11
    image12
    5 use a drive pinion that is engaged in a drive with a toothed belt as the drive means.
    Several examples of embodiments of suspensions are provided:
    10 -In the first embodiment according to Figures 2 to 4, in the second embodiment according to Figures 5 and 6 and in the fourth embodiment according to Figures 9 and 10, the cabin and the counterweight are suspended in a 2: 1 ratio In the 2: 1 suspension of the cabin 11, several deflection pulleys 13, 13 ', 14, are placed in the cabin 11
    15 14 '. In the 2: 1 suspension of the counterweight 12, at least 12 a deflection pulley 17, 17 'is placed in the counterweight 12. The driving machine is advantageously arranged in an area located essentially above the path of the counterweight, that is to say in the vertical projection above the counterweight. The driving machine is advantageously arranged in an area
    20 located essentially completely above the cab travel. The driving machine is advantageously arranged in an area located essentially above the path of the counterweight and of the cab, that is to say in the vertical projection above the counterweight and the cab.
    25 -In the third embodiment according to Figures 7 and 8, the cabin and the 1: 1 counterweight are suspended in a 1: 1 ratio. In this exemplary embodiment, the driving machine is advantageously arranged in an area essentially above the cab travel, that is in the vertical projection above the cab. In the third embodiment,
    30 the driving machine is advantageously arranged completely above the cab travel.
    image13
    Figure 2 shows a perspective view of a part of a first embodiment of the arrangement of a driving machine without gear 1, 2, 3, 3 ', 4. The driving machine is mounted on the crossbar 8, which is arranged in an essentially horizontal position in box 10. The crossbar is, for example, an elongated square profile of proven materials, such as steel. In this first embodiment, the crossbar is fixed to the counterweight guides 9, 9 'and to the cabin guide 5 of the first wall. The crossbar is advantageously fixed to the counterweight guides by means of two terminal zones and to the cabin guide by means of a central zone. The crossbar is fixed to these three guides in the three fixing zones, for example by screw connections.
    The drive machine is advantageously mounted on the crossbar 8 indirectly through a console 7. The console is advantageously mounted in the central area of the crossbar. The console is mounted on the crossbar 8 for example by means of legs 7.5, 7.6. The console consists, for example, of flat or square profiles of proven materials, such as steel, and is mounted on the crossbar, for example, by screw connections. The drive machine is advantageously fixed to the console by means of a motor housing and a brake housing. The motor housing is advantageously fixed to a first console bracket 7.1 and the brake housing is advantageously fixed to a second console support 7.2. The two console supports 7.1, 7.2 are rigidly connected to each other in relation to the shaft of the shaft 4 for example by means of braces 7.3, 7.4. Console brackets 7.1, 7.2 advantageously cover, at least in certain areas, some delimitations of the motor housing or the brake housing. For example, console brackets 7.1, 7.2 cover front surfaces of the motor housing or the brake housing. The motor 1 and the brake 2 are advantageously arranged in an area essentially outside a shell of the console 7, while the driving pulleys 3, 3 'are arranged in an area essentially located within the shell of the console 7.
    The crossbar 8 is fixed at least to the vertices of the triangle T and is advantageously supported with two end zones in the counterweight guides 9, 9 'and laterally supported with the central area in at least one cabin guide 5, 5'.
    image14
    Several examples of embodiments of crossbar fasteners are provided:
    -In the exemplary embodiment according to Figures 2 to 4 - in which the driving machine is arranged in an area essentially above the counterweight path - the cross member 8 is fixed to the counterweight guides 9, 9 'and the guide cabin 5 of the first wall, which is the closest to the counterweight guides 9, 9 'and to the cabin guide 5. The cross member is in the shape of a rectangle.
    -In the exemplary embodiment according to Figures 5 to 10 - in which the driving machine is arranged in an area essentially above the path of the counterweight and / or the cab - the cross member 8 is fixed to the counterweight guides 9, 9 'and to the cabin guide 5 of the first wall and / or to the cabin guide 5' of the second wall. In the exemplary embodiments according to Figures 5 to 8, the crossbar has a triangular shape with straight or curved sides and in the exemplary embodiment according to Figures 9 and 10 it has a T-shape.
    The console 7 and the driving pulleys 3, 3 'are advantageously arranged in a central area of the triangle T. The console is advantageously mounted in the central area of the crossbar. For example, in the first embodiment according to Figure 2, the legs 7.5, 7.6 of the console 7 are mounted on both sides of the car guide 5, 5 'and essentially at the same distance from the car guide 5, 5 'on the crossbar 8. For example, the driving pulleys 3, 3' are arranged on both sides of the car guide 5, 5 'and essentially at the same distance from the car guide 5, 5' in the shaft 4 .
    Accordingly, the driving machine can be arranged freely at the surface of triangle T essentially above the counterweight and / or essentially above the cab. Through this symmetrical arrangement of the guides in triangle T, the weight of the driving machine and the bending moments that occur during the operation of the driving machine are effectively absorbed for example by the console and transmitted to the floor of the box through of the crossbar and the guides. The guides are supported on the floor of the box by
    image15
    5 example by means of base plates.
    In the exemplary embodiment according to Figure 2, for example, the first console support 7.1 absorbs the driving forces from the motor 1 and the second console support 7.2 absorbs the braking forces from the brake 2.
    10 Both console supports 7.1, 7.2 also absorb the forces from the 3, 3 'drive pulleys. The two drive pulleys 3, 3 'are advantageously arranged symmetrically, to the left and to the right of the horizontal line joining the cabin guides 5, 5'.
    15 In the exemplary embodiments according to Figures 5 to 8 - in which at least one deflection pulley 15, 15 ', 16, 16' - is provided in the area above the counterweight and / or essentially above the cab Crossbar 8 can also absorb forces from this deflection pulley. This deflection pulley is advantageously fixed to the crossbar 8 or to the console
    20 7. Advantageously, pairs of deflection pulleys 15, 15 ', 16, 16' are arranged symmetrically, to the left and to the right of the horizontal line connecting the cabin guides 5, 5 '. Through the number and position of the deflection pulleys, flexibility in the arrangement of the driving machine on the surface of the triangle is made possible. In particular, a large
    25 taking advantage of the volume of the box, largely avoiding dead volume. The arrangement of the driving machine can also be adapted flexibly to predefined box conditions precisely in the case of modernizations, flexibility that allows therefore the use of standard parts and avoids expensive special solutions.
