Description

Technical Field

[0001] The present invention relates to a lift car and a lift, where the lift is a lift for transporting passengers and / or goods. Background Art

[0002] Such lifts are known, where the lift car is suspended by hoist ropes via one or more rope pulleys mounted on the car. In these lifts, the ropes generally run from a fixed point near the upper end of the hoistway, down to the rope pulleys of the car, around them, and back up to the upper end of the hoistway and to the drive wheel of the hoisting machine. The hoist ropes can thus pass back and forth once or several times, depending on the desired lifting ratio. The hoist ropes can transmit force in their longitudinal direction from the hoisting machine to the car. In such a lift, in addition to the desired suspension force, some vibrations are also liable to be transmitted from the hoisting machine via the hoist ropes to the car. Such vibrations reduce the riding comfort inside the car.

[0003] Such cars are known, where vibrations transmitted from the hoisting machine are attenuated by providing an elastically deformable support member, such as an elastic material pad, somewhere between the pulley and the car frame, such as between the pulley frame and the car frame. A disadvantage of the known solution is that it is difficult to avoid the transmission of vibrations and to connect the pulley frame and the car frame relatively rigidly to each other, but allow relative movement so that the elastically deformable support member has room to act as required. Summary of the Invention

[0041] Hereinafter, the present invention will be described in more detail by way of example and with reference to the accompanying drawings, in which:

[0042] Figure 1 An embodiment of the car is schematically illustrated from the side.

[0043] Figure 2 Is illustrated from its right side Figure 1 of the lower part of the car.

[0044] Figure 3 Is schematically illustrated as connectedFigure 1 The parallel motion link mechanism of the car frame and the pulley frame.

[0045] Figures 4 to 6 Illustrated is Figure 3 Additional preferred details of the car and the parallel motion link mechanism.

[0046] Figure 7 Illustrated is a lift according to an embodiment.

[0047] Figure 8 Illustrated are additional preferred details of the car. Detailed description

[0048] Figure 1 Illustrated is a lift car C according to an embodiment. The lift car C includes a pulley frame 1; and a car frame 2 which is mounted on the pulley frame 1; and one or more pulleys 4 which are mounted on the pulley frame 1. The lift car C includes a car structure 5a, 5b, 5c, 5d which defines a car interior I of the car 1 mounted on the car frame 2. The car structure 5a, 5b, 5c, 5d which defines the car interior particularly includes a floor panel 5a, a wall panel 5b, a ceiling panel 5c and a door 5d herein.

[0049] Furthermore, the lift car C includes one or more elastically deformable support members 6 which are between the car frame 2 and the pulley frame 1, and the car frame 2 is rested on or at least can be rested on the pulley frame 1 via the one or more elastically deformable support members 6. Due to the elastically deformable support member(s) 6, the car frame 2 can be vertically supported such that most of the vibrations transmitted from the hoist are attenuated and do not reach the car structure. The elastically deformable support member(s) 6 can also respond well to different load conditions of the car 1.

[0050] The lift car C further comprises at least one parallelogram linkage 7; 7A, 7B, which pivotally connects the car frame 2 to the sheave frame 1 and is arranged to allow the car frame 2 to pivot vertically relative to the sheave frame 1 while maintaining their relative angle constant. Thus, lateral support and direction control can be simply provided between the car frame 2 and the sheave frame 1, and they are allowed to move freely vertically relative to each other. The degree of freedom for the car frame 2 and the sheave frame 1 to move vertically relative to each other is required for good vibration damping of at least one elastically deformable support member 6. Thus, in all vibration cases and all load cases of the car 1, the deformable support member(s) 6 also serves as the main vertical load-bearing member between the car frame 2 and the sheave frame 1. The ability of the parallelogram linkage 7; 7A, 7B to maintain the relative angle between the car frame 2 and the sheave frame 1 constant is advantageous because thereby the car 1 can hold the sheave frame 1 in an upright position without the risk of it being distorted into an incorrect position. On the other hand, the rest of the car 1, such as the car frame 2, is easily maintained in an upright position by guide members 9 arranged to engage with the guide rails 11. Thus, the car frame 2 provides horizontal support for the parallelogram linkage 7; 7A, 7B of the sheave frame 1 to hold it in an upright position and correctly position it in the horizontal direction. On the other hand, the sheave frame 1 provides vertical support for the car frame 2 via the elastically deformable member(s) 6.

[0051] In a preferred embodiment, each of the elastically deformable members 6 is placed in a gap G which is located vertically between the sheave frame 1 and the car frame 2. Thus, the vertical support is simply transmitted between the car frame 2 and the sheave frame 1. The gap G is arranged to be enlarged when the car frame 2 pivots upwards relative to the sheave frame 1 and to narrow when the car frame 2 pivots downwards relative to the sheave frame 1. The elastically deformable member 6 is arranged to elastically resist the narrowing of the gap G. The elastically deformable member 6 is arranged to act as a compression spring.

[0052] In a preferred embodiment, the lift car 1 comprises one or more guide members 9 for guiding the movement of the car 1 along one or more guide rails 11, and the one or more guide members 9 are mounted on the car frame 2. The one or more guide members 9 can provide lateral support for the car 1. The one or more guide members 9 are preferably rolling guide members or sliding guide members as shown. Preferably, there are a plurality of the guide members 9, including guide members 9 at different vertical heights, which facilitates guiding the car 1 in an upright attitude.

[0053] In a preferred embodiment, the pulley frame 1 is located in the bottom region of the car 1. The one or more pulleys 4 include a first pulley 4a and a second pulley 4b, which are arranged to rotate about parallel horizontal axes Xa, Xb in the same rotational plane. The first pulley 4a and the second pulley 4b are arranged to / or at least adapted to be arranged to guide the hoisting rope 10 from one side of the car 1 to the other side (opposite side) of the car 1 passing under the car 1.

[0054] Figure 3 Schematically illustrates the structure of the pantograph link mechanisms 7; 7A; 7B. Figures 4 to 6 Illustrates further preferred details thereof.

[0055] In a preferred embodiment, the pantograph link mechanisms 7; 7A; 7B include a first lever 71, which is connected to the pulley frame 1 via a first pivot 71a and to the car frame 2 via a second pivot 71b; and a second lever 72, which is connected to the pulley frame via a third pivot 72a and to the car frame via a fourth pivot 72b.

[0056] The first pivot 71a, the second pivot 71b, the third pivot 72a and the fourth pivot 72b are positioned such that the pivot axis X1 of the first pivot 71a and the pivot axis X3 of the third pivot 72a are in a first plane P1, and the pivot axis X2 of the second pivot 71b and the pivot axis X4 of the fourth pivot 72b are in a second plane P2, where the first plane P1 and the second plane P2 are parallel to each other; and the pivot axis X1 of the first pivot 71a and the pivot axis X2 of the second pivot 71b are in a third plane P3, and the pivot axis X3 of the third pivot 72a and the pivot axis X4 of the fourth pivot 72b are in a fourth plane P4, where the third plane P3 and the fourth plane P4 are parallel to each other. Thus, the levers 71, 72 control the movement of the pulley frame 1 and the car frame 2 such that their relative angles remain unchanged.

[0057] The pivot axes X1, X2, X3, X4 of the first pivot 71a, the second pivot 71b, the third pivot 72a and the fourth pivot 72b are horizontal. The first plane P1 and the second plane P2 are preferably vertical. The first plane P1 and the second plane P2 are adjacent to each other, and the third plane P3 and the fourth plane P4 are superposed on each other. The third plane P3 and the fourth plane P4 are superposed on each other preferably at an angle less than 30 degrees with respect to the horizontal plane, more preferably at an angle less than 15 degrees with respect to the horizontal plane. Thus, when there is a vertical movement between the car frame 2 and the pulley frame 1, substantially no lateral movement occurs. The angles of the third plane P3 and the fourth plane P4 with respect to the horizontal plane change when the pantograph link mechanisms 7; 7A, 7B pivot.

[0058] In a preferred embodiment, the pulley frame 3 is mounted on the car frame 2 by means of two parallelogram linkage mechanisms 7; 7A, 7B, in particular a first parallelogram linkage mechanism 7A and a second parallelogram linkage mechanism 7B, which two parallelogram linkage mechanisms 7A, 7B are horizontally displaced from one another, and the pivot axes X1, X2, X3, X4 of the first parallelogram linkage mechanism 7A are arranged to coincide with the pivot axes X1, X2, X3, X4 of the second parallelogram linkage mechanism 7B.

[0059] The car frame 2 can be made of a plurality of parts 2a - 2c which are fixed to one another, for example, by means of bolted connections and / or welding. These parts 2a - 2c can include beams 2b, 2c, for example, in the illustrated embodiment. However, the specific structure of the car frame 2 can also be different.

[0060] In a preferred embodiment, the parts 2b of the car frame 2 to which the levers 71, 72 are connected via pivot pins 71b, 72b are the bottom corner parts 2b of the car frame 2. The part 2a of the car frame 2 is a horizontal beam via which the car frame 2 is or at least can be rested on the pulley frame 1. In a preferred embodiment, the beam 2a is rested on an elastically deformable support member 6.

[0061] In a preferred embodiment, the lift car C includes two of the said parallelogram linkage mechanisms 7; 7A, 7B. This facilitates a more uniform force distribution and the stability and control of the relative movement between the frames 1 and 2. More specifically, there are two of the said bottom corner parts 2b and two of the said parallelogram linkage mechanisms 7; 7A, 7B. The levers 71, 72 of the two parallelogram linkage mechanisms 7A, 7B are connected to opposite faces of the car frame 2, in particular to opposite faces of the two corner parts 2b of the car frame 2. The opposite faces facilitate that the two parallelogram linkage mechanisms 7A, 7B do not occupy space on the sides of the car 1. However, such a space-saving positioning is not necessary, and the connection, in particular to the corner parts 2b as described above, is also not necessary, since the levers 71, 72 of each parallelogram linkage mechanism 7, 7A, 7B can be connected via pivot pins 71b, 72b to any suitable face of the car frame 2, such as alternatively to any outer surface of the frame 2, for example, if the increased space consumption in this area is acceptable. Figure 8 Illustrated is how the two parallelogram linkage mechanisms 7, 7A, 7B are preferably arranged. In the figure, many features of the car 1 are omitted in order to make its internal structure visible. Figure 8 Illustrated are the beam 2d of the car frame 2 and the diagonal strut 2e of the car frame 2, which are not visible in other figures.

[0062] The structure of the pivot is preferably such that each of the pivots 71a, 72a, 71b, 72b includes a shaft pin, such as a bolt member, which is arranged to pass through an opening, such as a hole, in the levers 71, 72. Preferably, one or more of the pivots 71a, 72a, 71b, 72b include a bushing made of plastic or elastomer or rubber, which bushing surrounds the shaft pin in the opening. Preferably, one or more of the pivots 71a, 72a, 71b, 72b include a bushing b made of plastic or elastomer or rubber, via which the levers 71, 72 are supported in place in the axial direction. The bushing made of plastic or elastomer or rubber can attenuate vibrations transmitted to the levers 71, 72 of the parallel motion link mechanism 7; 7A, 7B and vibrations transmitted from the levers 71, 72.

[0063] The elastically deformable support member 6 is preferably fixed to at least one of the car frame 2 and the pulley frame 1.

[0064] The elastically deformable support member 6 is preferably an elastically deformable pad, such as a block made of an elastic material such as an elastomer or rubber.

[0065] Figure 7 An elevator 100 according to one embodiment is illustrated. The elevator 100 includes an elevator car 1 described with reference Figures 1 to 6 and 8.

[0066] The elevator 100 includes a hoisting rope 10, which is arranged to suspend the elevator car 1 via one or more pulleys 4 of the car 1. The hoisting rope 10 is arranged to bypass one or more pulleys 4 of the car 1.

[0067] The elevator 100 includes guide rails 11 for guiding the movement of the car 1, and the car 1 includes a guiding member 9, which is mounted on the car frame 2 and is arranged to move by sliding or rolling along one or more guide rails 11.

[0068] The elevator 100 includes a motor 12 and a drive wheel 13 that can be rotated by the motor 12, and an elevator control system 14, which is configured to control the movement of the car 1 in response to signals received from one or more user interfaces, such as user interfaces located at one or more landings and / or user interfaces located inside the car 1, in particular by controlling the rotation of the motor 12 to control the movement of the car 1.

[0069] Generally, preferably, as shown, the suspension ratio of the car is 2:1. However, alternatively, some other suspension ratio, such as 4:1, for example, or any other known suspension ratio can be used.

[0070] Generally, in the present application, the features of the car 1 are described in a state where the car 1 is in an upright position.

[0071] Generally, preferably, the at least one elastically deformable support member is arranged to carry all or at least most (i.e., greater than 50%) of the total weight of the car frame 2 and the components mounted thereon. Thus, the at least one elastically deformable support member 6 serves as the main means for supporting the car frame 2 and the components carried thereby.
