    [0002] Equalization system of suspension members for elevators
    [0003]
    [0004] RELATED APPLICATIONS
    [0005] This application claims the benefit of the United States Provisional Application No.
    [0006] 62 / 511,593, filed on May 26, 2017, whose disclosure is incorporated herein by reference in its entirety.
    [0007]
    [0008] BACKGROUND
    [0009] Traction elevators use a plurality of suspension members to drive an elevator car in an upward and downward direction within the opposite guide rails. Suspension members may have various shapes, including non-limiting examples of cables and straps. The suspension members can be operated by various devices, including the non-limiting example of a pulley traction machine.
    [0010]
    [0011] A well-adjusted traction lift includes suspension members that have equal tension between them. The same tension in the suspension members can extend the life of the suspension members and associated equipment, such as the drive pulley of the traction machine. It is known that an amount as small as 10% of unequal tension can reduce the life of the set of suspension members by approximately 30%.
    [0012]
    [0013] It would be advantageous if the respective tensions in the suspension members could be adjusted automatically as the elevator is operated.
    [0014]

    [0050]
    [0051] With reference now to the drawings, a schematic and simplified view of a traction elevator 10 (hereinafter "elevator") is illustrated in Figure 1. The elevator 10 includes an elevator car 12, configured to move in a substantially vertical direction on the opposite car guide rails (not shown for simplicity). The elevator car 12 and the car guide rails are arranged in an elevator box 14.

The suspension members 16 may consist of multiple ropes, flat belts or other suitable structures.
    [0052]
    [0053] Referring again to Figure 1, a second segment of the one or more suspension members 16 is configured to support a counterweight assembly 20. The counterweight assembly 20 is configured to balance a portion of the weight of the elevator car 12 and the nominal capacity of the elevator car 12. The counterweight assembly 20 moves in a substantially vertical direction on the opposite guide rails of the counterweight 22.
    [0054]
    [0055] With reference again to Figure 1, the elevator box 14 can be divided vertically into building floors (not shown). The floors of the building may have entrances (not shown) configured to facilitate the entry and exit of the elevator car 12.
    [0056]
    [0057] Referring again to Figure 1, a first end 24 of the suspension members 16 can be fixed to a first device 26. Similarly, a second end 28 of the suspension members 16 can be fixed to a second device 30 .
    [0058]
    [0059] While the structures of the first and second devices 26, 30 illustrated in Figure 1 are described in relation to a traction lift 10 having a 2: 1 suspension system, it should be appreciated that the first and second devices 26, 30 are they can be incorporated into traction elevators that have other suspension systems, including non-limiting examples of 1: 1, 4: 1.6: 1 and suspended suspension systems.
    [0060]
    [0061] Referring now to Figure 2, the first device 26 is illustrated. The first accessory 26 may be illustrative of the second accessory 30. A plurality of members of suspension 16a-16d. Each suspension member 16a-16d is attached to a suspension member receptacle 32a-32d. The receptacles of the suspension member 32a-32d are known in the art. The receptacles of the suspension member 32a-32d include rods 34a-34d having threaded ends 36a-36d. The bars 34a-34d are configured to extend through a mounting plate 38. The mounting plate 38 is designed for minimal deflection and can be fixed to any suitable structural member, including non-limiting examples of a car or rail counterweight guide, beam machine, hollow wall, sufficient to support the weight of the car 12. However, in other embodiments, the mounting plate 38 can be removed and the terminations of the suspension member can be attached directly to the other suitable structures.
    [0062]
    [0063] Referring again to Figure 2, the first accessory 26 includes a plurality of cylinder assemblies 40a-40d. Each of the cylinder assemblies 40a-40d is axially aligned with the respective rod 34a-34d.
    [0064]
    [0065] Referring now to Figure 3, the suspension member 16a, the receptacle of the suspension member 32a, the rod 34a, the threaded end 36a and the cylinder assembly 40a are illustrated and are representative of the suspension members 16b-16d, the suspension member receptacle 32b-32d, rods 34b-34d, threaded ends 36b-36d and cylinder assemblies 40b-40d. The suspension member 16a, the receptacle of the suspension member 32a, the rod 34a, the threaded end 36a are longitudinally aligned along the axis A-A. As will be explained in more detail below, the cylinder assembly 40a is configured to receive the threaded end 36a of the rod 34a so that the threaded end 36a passes through it and the cylinder assembly 40a is also axially aligned with the Axis. A - A.
    [0066]
    [0067] Referring again to FIG. 3, the cylinder assembly 40a is secured in place between an upper surface 42a of an upper swing plate 60a and a lower surface 46a of an upper washer 48a by a first nut 50a, a lock nut 52a and a plug (not shown). The cylinder assembly 40a is configured to exert an axial force on the rod 34a.
    [0068]
    [0069] Referring again to Figure 3, a lower oscillating plate 62a is positioned between the upper oscillating plate 60a and the mounting plate 38. The cylinder assembly 40a, the upper oscillating plate 60a and the lower oscillating plate 62a have annular shapes and respective openings, thus allowing rod 34a to pass through it.
    [0070] Referring again to Figure 3, a part of the weight of the elevator car 12 and the nominal capacity of the elevator car 12 is supported by the suspension member 16a. The part of the weight of the elevator car 12 and the nominal capacity of the elevator car 12 is detected by the cylinder assembly 40a, which is compressed in proportion to the load.
    [0071]
    [0072] Referring again to Figure 3, the cylinder assembly 40a includes a cylinder port 64a. A first end 65a of a first conduit, shown schematically at 66a, is connected to the port of the cylinder 64a. The cylinder port 64a is configured for unidirectional fluid communication from the conduit 66a within an internal cavity 76a. In the illustrated embodiment, the port of the cylinder 64a is in the form of a ball valve. However, in other embodiments, the port of the cylinder 64a may have other forms sufficient for a unidirectional fluid communication from the conduit 66a to an internal cavity 76a. The first conduit 66a is configured for the passage of a fluid within it.
    [0073]
    [0074] Referring now to Figure 4, a manifold block 68 is illustrated. The manifold block 68 includes a plurality of exterior walls configured to define a manifold cavity 70 therein. Multiple block 68 includes a first multiple port 72a, a second multiple port 72b, a third multiple port 72c and a fourth multiple port 72d. A second end 67a of the first conduit 66a is connected to the first port of the manifold 72a such that the first conduit 66a is in fluid communication with the cavity of the manifold 70.
    [0075]
    [0076] Referring again to Figure 4, a second conduit 66b extends from the cylinder port 64b of the mounting cylinder 40b to the second manifold port 72b, a third conduit 66c extends from the connection of the cylinder 64c of the cylinder assembly 40c to the third port of the distributor 72c and a fourth conduit 66d extend from the cylinder port 64d of the cylinder assembly 40d to the fourth port of the distributor 72d. Ports 64a-64d, 72a-72d and conduits 66a-66d are configured to allow simultaneous communication of fluids between cylinder assemblies 40a-40d and manifold cavity 70.
    [0077]
    [0078] Referring again to Figure 4, a connector port 74 is connected to the manifold block 68 and configured to facilitate fluid communication between the collector cavity 70 and an external source (not shown). As will be explained in more detail below, the connector port 74 is used to supply an incompressible fluid to the manifold block 68, the ducts 66a-66d and the cylinder assemblies 40a-40d.
    [0079] Referring now to Figures 5A and 5B, the cylinder assembly and 40a are illustrated. The cylinder assembly 40a is in contact with the upper oscillating plate 60a and the upper oscillating plate 60a is seated against the lower oscillating plate 62a. The cylinder assembly 40a includes a housing 75a configured to define the internal cavity and 76a. A piston 78a is mounted for a sliding axial movement within the internal cavity 76a. The housing 75a is configured to support the port of the cylinder 64a and an internal passage 80a that provides fluid communication between the port of the cylinder 64 and the internal cavity 76a. As will be explained in more detail below, the internal cavity 76a is configured to receive fluids from the internal passage 80a.
    [0080]
    [0081] Referring now to Figure 5B, the housing 75a has a circular cross-sectional shape and a diameter D. The diameter D is configured such that the cylinder assemblies 40a-40d can fit between the receptacles of the suspension member 32a- 32d without interference between intakes of adjacent suspension members 32a-32d. In the illustrated embodiment, the diameter D is in a range of about 2.0 inches (5.08 cm) to about 4.0 inches (10, 15 cm). However, in other embodiments, the housing 75a may have other cross-sectional shapes and the diameter D may be less than about 2.0 inches (5.08 cm) or more than about 4.0 inches (10, 15 cm) , sufficient so that the cylinder assemblies 40a-40d can fit between the receptacles of the suspension member 32a-32d without interference between the adjacent receptacles of the suspension member 32a-32d
    [0082]
    [0083] Referring now to Figures 2, 4 and 5B, in operation, a conduit 66a-66d is connected to each of the cylinder assemblies 40a-40d and the manifold ports 72a-72d in such a way as to allow fluid communication between the cylinder assemblies 40a-40d and the collecting cavity 70. The port of the connector 74 is also connected to the block of the manifold 68. In the next step, the port of the connector 74 is connected to an external source of incompressible fluid and the incompressible fluid It is supplied to the cavity of the manifold 70, ducts 66a-66d and to the internal cavities 76a-76d of the cylinder assemblies 40a-40d such that they fill the distributor cavity 70, the ducts 66a-66d and the internal cavities 76a- 76d In the illustrated embodiment, the incompressible fluid is hydraulic fluid. However, in other embodiments, the incompressible fluid may be other fluids. In an optional next step, the system comprising the internal cavities 76a-76d of the cylinder assemblies 40a40d, the ducts 66a-66d and the manifold cavity 70 of the manifold block 68 can be "bled" to remove trapped air with The incompressible fluid.
    [0084] Referring again to Figures 2, 4 and 5B, given that all structures containing incompressible fluids, namely the internal cavities 76a-76d of the cylinder assemblies 40a-40d, the ducts 66a-66d and the collecting cavity 70 of the manifold block 68 are simultaneous in fluid communication, the pistons 78a-78d within each of the cylinder assemblies 40a-40d will seek approximately equal pressure and approximately equal tension in each of the suspension members 16a-16d. The equalization of the pressures within the cylinder assemblies 40a-40d and the equalization of the tension in each of the suspension members 16a-16d can result in the pistons 78a-78d extending over unequal distances beyond housings 75a-75d, as clearly shown in Figure 2. Without adhering to the theory, it is believed that the oil-containing structures, namely the internal cavities 76a-76d of the cylinder assemblies 40a-40d, the ducts 66a -66d and the collecting cavity 70 of the collecting block 68 operate according to the "communicating vessels" principle, thus allowing the tension in the suspension members 16a-16d to equalize at any time and not only during non-use of the elevator. The first nuts 50a can be tightened to keep the pistons 78a in their relative positions.
    [0085]
    [0086] Referring now to Figures 6-8, a lower portion 82a of the cylinder assembly 40a is illustrated together with the upper oscillating plate 60a and the lower oscillating plate 62a. The cylinder assembly 40a includes an internal circumferential wall 84a and a partition 86a. The inner circumferential wall 84a and the partition 86a cooperate to form a cavity 88a. A plurality of separate projections 90a extend from the partition 86a of the cylinder assembly 40a. The projections 90a extend in a direction towards the upper oscillating plate 60a. In the illustrated embodiment, a quantity of three (3) projections 90a are spaced within a radius consisting of equal angles of 120 °. The consistent radius of the equally spaced projections 90a is configured to define a location for the introduction of force into the cylinder assembly 40a. That is, the cylinder assembly 40a receives the compression force at defined locations of the partition 86a. Without being limited to the theory, it is believed that the defined location of the introduction of force into the cylinder assembly 40a contributes to the reliable and repeatable operation of the cylinder assembly 40a. However, in other embodiments, more or less than three (3) projections 90a can be used and the projections 90a can be separated by other angles sufficient to define a location for the introduction of force into the cylinder assembly 40a.
    [0087]
    [0088] Referring again to Figures 6-8, the upper oscillating plate 60a includes an annular track 94a located on an upper surface 96a of the upper oscillating plate 60a. With the plate upper swing 60a in a seating arrangement within the cavity 88a of the cylinder assembly 40a, the upper surface 96a of the upper swing plate 60a is seated against the partition 86a of the cylinder assembly 40a and the plurality of projections 90a extending from The partition 86a of the cylinder assembly 40a is received by the annular track 94a in the upper oscillating plate 60a. In this way, the upper oscillating plate 60a is radially centered around the cylinder assembly 40a. When settling on track 94a, the plurality of projections 90a prevents radial sliding of the cylinder assembly 40a with respect to the upper oscillating plate 60a. Without following the theory, it is believed that the structure of the projections seated 90a within the track 94a contributes to the location of the introduction of defined force of the cylinder assembly 40a, which contributes to the precise, reliable and repeatable operation of the assembly of 40a cylinder
    [0089]
    [0090] With reference again to Figures 6-8, each of the projections 90a has the shape of cubes or squares. However, in other embodiments, the projections 90a may have other shapes, such as the non-limiting example of a circular structure, sufficient to be received on the track 94a of the upper oscillating plate 60a and contribute to the location of the defined force introduction of the cylinder assembly 40a. It is also within the contemplation of the equalization system of the suspension member that the projections 90a may have different shapes from each other.
    [0091]
    [0092] Referring again to Figures 6-8, the upper oscillating plate 60a includes an annular recess 97a configured to receive an annular coupling projection 98a extending from the lower oscillating plate 62a. With the upper oscillating plate 60a and the lower oscillating plate in a nested position, the annular projection 98a is in sliding contact with the annular recess 97a of the upper oscillating plate 60a. The recess 97a of the upper oscillating plate 60a and the projection 98a are configured for various functions. First, the recess 97a of the upper oscillating plate 60a and the projection 98a are configured such that the upper oscillating plate 60a and the lower oscillating plate 62a can rotate with respect to each other to compensate for the misalignment of the mounting plate 38 and the rod 34a extending upwardly through the mounting plate 38. Second, since the recess 97a of the upper oscillating plate 60a and the projection 98a are configured to rotate relative to each other, the upper oscillating plate 60a and the Lower swing plate 62a cooperate with each other to contribute to the location of the defined force introduction of the cylinder assembly 40a.
    [0093]
    [0094] Referring again to Figures 6-8, the annular recess 97a has the shape of a hollow cavity and the annular projection 98a has the shape of a hollow dome. However, in others embodiments, annular recess 97a and annular projection 98a may have other forms of coupling sufficient for the functions described herein.
    [0095]
    [0096] Referring again to Figure 5B, in a nested arrangement, the oscillating plates 60a, 62a cooperate with the lower portion 82a of the cylinder assembly 40a to provide several unexpected benefits. First, nested oscillating plates 60a, 62a align the cylinder assembly 40a so that it is substantially parallel to the rod 34a (shown in phantom form for clarity), even if the rod 34a is arranged in an inclined orientation relative to the mounting plate 38. Regardless of the theory, it is believed that if the oscillating plates 60a, 62a did not align the cylinder assembly 40a to be substantially parallel to the rod 34a, then a part of the tension in the suspension a member would act orthogonally on the cylinder assembly 40a, which would result in the destruction of the cylinder assembly 40a or the need to use a cylinder assembly 40a having a much larger diameter D. Second, the nested oscillating plates 60a, 62a provide a defined force introduction location in the cylinder assembly 40a. That is, the cylinder assembly 40a receives the compression force of the upper oscillating plate 60a at the defined location of the partition 86a. Without limiting the theory, it is believed that the location of defined force introduction provides several benefits. First, the defined force introduction location contributes to the reliable and repeatable operation of the cylinder assembly 40a. Secondly, the defined force introduction location allows the cylindrical cylinder assembly 40a to have a small diameter, thus allowing cylinder assemblies 40a-40d to be permanently mounted in the installation. Finally, the tension in the suspension members 16a-16d is equalized at all times and not only during non-use of the elevator.
    [0097]
    [0098] The principle and mode of operation of the equalization system of the suspension member for elevators have been described in certain embodiments. However, it should be borne in mind that the equalization system of the elevator suspension member can be practiced other than that illustrated and specifically described without departing from its scope.
