TECHNICAL FIELD
[0001] The present application relates to the elevator technical field, and particularly relates to an elevator system. BACKGROUND
[0002] Nowadays, elevator systems are widely used in various buildings to automatically transport passengers from a starting floor to a target floor, which not only relieves the hard work caused by climbing stairs, but also greatly improves the efficiency of passing. The commonly used elevator system at present is usually a traction elevator. A traction machine is installed at the top of a shaft, and the traction machine is connected with a car through a traction rope to pull or release the car to make the car run up and down in the shaft. However, for some high-rise or even super high-rise buildings, the height of the shaft is too high, which causes the length of the traction rope to be very long. Therefore, the traction rope is easily pulled and broken due to the weight of the car, counterweight and itself. Therefore, a new type of elevator system using a linear motor to drive the car to move in the shaft appears in the industry. The working principle is that a mover coil is installed on the car, and a stator is installed on the track (or a stator can be installed on the car, and a mover coil is installed on the track). The magnetic field force between the mover coil and the stator is used to drive the car to move along the guide rail.
[0003] However, the existing elevator system using a linear motor to drive the car has a structural design defect, which causes a large unbalanced load during the hovering and running of the car, and the car cannot run smoothly, which affects the comfort and experience of taking the elevator. SUMMARY
[0004] Therefore, it is necessary to provide an elevator system to solve the problem that the unbalanced load affects the smooth running of the car and causes poor comfort and experience of taking the elevator.

[0046] Referring to Figure 1 , Figure 2 and Figure 3 , an elevator system 100 according to an embodiment of the present application is shown, which includes a shaft 10, a first longitudinal guide rail group 20 and a second longitudinal guide rail group 30 arranged opposite to each other, a first transverse guide rail group 40 and a second transverse guide rail group 50 arranged opposite to each other, a longitudinal stator permanent magnet 60, a transverse stator permanent magnet 70, and a car 80.
[0047] For example, when the cross section of the shaft 10 is rectangular, the first longitudinal guide rail set 20 and the second longitudinal guide rail set 30 are arranged opposite to each other in the width direction of the shaft 10, and the first transverse guide rail set 40 and the second transverse guide rail set 50 are arranged opposite to each other in the width direction of the shaft 10 and extend along the length direction of the shaft 10.
[0048] The first longitudinal guide rail set 20 and the second longitudinal guide rail set 30 are arranged to extend along the vertical direction of the shaft 10. It can be understood that the first longitudinal guide rail set 20 and the second longitudinal guide rail set 30 are used to provide support and guidance required for the car 80 to move up and down in the shaft 10.
[0049] The first transverse guide rail set 40 and the second transverse guide rail set 50 are arranged to extend along the horizontal direction of the shaft 10, and the first transverse guide rail set 40 is arranged on the first longitudinal guide rail set 20, and the second transverse guide rail set 50 is arranged on the second longitudinal guide rail set 30. It can be understood that the first transverse guide rail set 40 and the second transverse guide rail set 50 are used to provide support and guidance required for the car 80 to move horizontally in the shaft 10.
[0050] Please continue to refer to Figure 3 and Figure 6 , the longitudinal stator permanent magnet 60 is arranged on the first longitudinal guide rail set 20 and the second longitudinal guide rail set 30; the transverse stator permanent magnet 70 is arranged on the first transverse guide rail set 40 and the second transverse guide rail set 50; the car 80 is arranged in the shaft 10, and the car 80 includes a top transverse beam 81 arranged at the top and a bottom transverse beam 82 arranged at the bottom, and the opposite ends of the top transverse beam 81 are provided with a top mover assembly 83, the top mover assembly 83 can be magnetically coupled with the longitudinal stator permanent magnet 60 or the transverse stator permanent magnet 70, and the opposite ends of the bottom transverse beam 82 are provided with a bottom mover assembly 84, the bottom mover assembly 84 can be magnetically coupled with the longitudinal stator permanent magnet 60 or the transverse stator permanent magnet 70.
[0051] It can be understood that the top mover assembly 83 and the bottom mover assembly 84 are connected to the elevator control cabinet by cable or wireless mode, and the on-off of the top mover assembly 83 and the bottom mover assembly 84, the input current size and the like are adjusted and controlled by the elevator control cabinet.
[0052] When the top mover assembly 83 and the bottom mover assembly 84 are connected to the current, the magnetic field force is generated. When the magnetic field force is coupled with the longitudinal stator permanent magnet 60, the magnetic driving force is generated to drive the car 80 to move vertically along the first longitudinal guide rail set 20 and the second longitudinal guide rail set 30 in the shaft 10, or when the magnetic field force is coupled with the transverse stator permanent magnet 70, the magnetic driving force is generated to drive the car 80 to move horizontally along the first transverse guide rail set 40 and the second transverse guide rail set 50 in the shaft 10.
[0053] In summary, the elevator system 100 of the above-mentioned scheme has the following beneficial effects: by simultaneously arranging the first longitudinal guide rail set 20 and the second longitudinal guide rail set 30 extending in the vertical direction and the first transverse guide rail set 40 and the second transverse guide rail set 50 extending in the horizontal direction in the shaft 10, and simultaneously arranging the top mover assembly 83 on the opposite ends of the top cross beam 81 of the car 80 and the bottom mover assembly 84 on the opposite ends of the bottom cross beam 82, when the car 80 moves vertically along the first longitudinal guide rail set 20 and the second longitudinal guide rail set 30 in the shaft 10 or reciprocally moves horizontally along the first transverse guide rail set 40 and the second transverse guide rail set 42 in the shaft 10, the symmetrically arranged top mover assembly 83 and the bottom mover assembly 84 on both sides can generate balanced magnetic field force between the longitudinal stator permanent magnet 60 or the transverse stator permanent magnet 70, thereby ensuring that the magnetic coupling effect tends to be consistent, ensuring that the posture of the car 80 remains stable during vertical or horizontal movement and avoiding the problem of unbalanced load, or even if there is an unbalanced load on one side of the car 80, the car 80 can be corrected to a stable posture by coordinating the magnetic field force generated between the top mover assembly 83 and the bottom mover assembly 84 on both sides of the car 80 and the longitudinal stator permanent magnet 60 or the transverse stator permanent magnet 70, eliminating the unbalanced load and its negative effects, ensuring that the car 80 can move smoothly in the shaft 10, improving the comfort and experience of taking the elevator.
[0054] Preferably, the top cross beam 81 and the bottom cross beam 82 are installed on the center line of the vertical section of the car 80, thereby physically eliminating the unbalanced load of the car 80 as much as possible.
[0055] Please continue to refer to Figure 2 , specifically, on the basis of the above-mentioned embodiment, the first longitudinal guide rail set 20 includes the first longitudinal guide rail 21 and the second longitudinal guide rail 22 arranged opposite at a horizontal interval, the first transverse guide rail set 40 includes the first transverse guide rail 41 and the second transverse guide rail 42 arranged opposite at a vertical interval, and the two ends of the first transverse guide rail 41 and the two ends of the second transverse guide rail 42 are respectively connected to the first longitudinal guide rail 21 and the second longitudinal guide rail 22 one by one.
[0056] The second longitudinal rail group 30 comprises a third longitudinal rail 31 and a fourth longitudinal rail 32 arranged oppositely and spaced apart, and the second transverse rail group 50 comprises a third transverse rail 51 and a fourth transverse rail 52 arranged oppositely and spaced apart vertically, and the two ends of the third transverse rail 51 and the fourth transverse rail 52 are connected to the third longitudinal rail 31 and the fourth longitudinal rail 32 correspondingly respectively.
[0057] Through the above structural design, on the one hand, the first longitudinal rail 21 and the second longitudinal rail 22 are supported by the shaft 10 side wall, and are stably installed, and also load and fix the first transverse rail 41 and the second transverse rail 42, so that the first transverse rail 41 and the second transverse rail 42 are stably installed, and the third longitudinal rail 31 and the fourth longitudinal rail 32 are stably installed in the same way; on the other hand, the two top mover assemblies 83 at the opposite ends of the top cross beam 81 are installed and matched with the first transverse rail 41 and the third transverse rail 51 (or the first longitudinal rail 21 and the third longitudinal rail 31) respectively, and the two bottom mover assemblies 84 at the opposite ends of the bottom cross beam 82 are installed and matched with the second transverse rail 42 and the fourth transverse rail 52 (or the second longitudinal rail 22 and the fourth longitudinal rail 32) respectively, so that the opposite sides of the car 80 are synchronously and evenly supported, the unbalanced load of the car 80 is avoided, and the smooth and stable operation of the car 80 is ensured.
[0058] Please continue to refer to Figure 3 and Figure 6 In some embodiments, the opposite sides of the first longitudinal rail group 20 and the second longitudinal rail group 30 are inwardly recessed with longitudinal guide grooves 90, and the longitudinal stator permanent magnets 60 are arranged in the longitudinal guide grooves 90 and are matched with the top mover assembly 83 and the bottom mover assembly 84 in a magnetic gap interval; the opposite sides of the first transverse rail group 40 and the second transverse rail group 50 are inwardly recessed with transverse guide grooves 90a, and the transverse stator permanent magnets 70 are arranged in the transverse guide grooves 90a and are matched with the top mover assembly 83 and the bottom mover assembly 84 in a magnetic gap interval.
[0059] On the one hand, the longitudinal stator permanent magnets 60 and the transverse stator permanent magnets 70 are arranged in the longitudinal guide grooves 90 and the transverse guide grooves 90a, so as to improve the installation reliability of the longitudinal stator permanent magnets 60 and the transverse stator permanent magnets 70; on the other hand, the top mover assembly 83 and the bottom mover assembly 84 need to extend into the longitudinal guide grooves 90 and the transverse guide grooves 90a so as to be oppositely spaced apart from the longitudinal stator permanent magnets 60 and the transverse stator permanent magnets 70, so as to ensure the magnetic field effect, each rail can effectively suppress the magnetic field loss, and the driving efficiency of the car 80 is improved.
[0060] Please continue to refer to Figure 2 , Figure 3 and Figure 6 Further, in the embodiment, the longitudinal guide slot 90 and the transverse guide slot 90a are both arranged in a "U" shape, the three side walls of the longitudinal guide slot 90 are each provided with a longitudinal stator permanent magnet 60, and the three side walls of the transverse guide slot 90a are each provided with a transverse stator permanent magnet 70; the top mover assembly 83 and the bottom mover assembly 84 each include a beam mover 90b and three mover coils 90c, the three mover coils 90c are respectively arranged on three different sides of the beam mover 90b, and the mover coils 90c are used to cooperate with the longitudinal stator permanent magnets 60 or the transverse stator permanent magnets 70 one by one.
[0061] By arranging more pairs of mover coils 90c and longitudinal stator permanent magnets 60 (vertical direction movement) or more pairs of mover coils 90c and transverse stator permanent magnets 70 (horizontal direction movement), the driving force for moving the car 80 can be enhanced, and the power demand for normal operation of the car 80 under heavy load conditions can be met.
[0062] It should be noted that the longitudinal stator permanent magnets 60 installed in the first longitudinal guide rail 21, the second longitudinal guide rail 22, the third longitudinal guide rail 31 and the fourth longitudinal guide rail 32 can be integrally extended along the longitudinal guide slot 90, or can be arranged in sequence by arranging multiple separate spaced-apart blocks; the transverse stator permanent magnets 70 installed in the first transverse guide rail 41, the second transverse guide rail 42, the third transverse guide rail 51 and the fourth transverse guide rail 52 can be integrally extended along the transverse guide slot 90a, or can be arranged in sequence by arranging multiple separate spaced-apart blocks.
[0063] It should be noted that in the present scheme, the first transverse guide rail group 40 and the second transverse guide rail group 50 can be more than one pair, for example, at least two pairs of first transverse guide rail groups 40 and second transverse guide rail groups 50 are installed in the vertical direction of the first longitudinal guide rail group 20 and the second longitudinal guide rail group 30 and correspond to at least one landing door 210, based on which, the car 80 in the present scheme can not be only one, specifically, one car 80 can correspond to each group of first transverse guide rail group 40 and second transverse guide rail group 50, each car 80 moves horizontally on its own group of first transverse guide rail group 40 and second transverse guide rail group 50, and different cars 80 can also move up and down on the first longitudinal guide rail group 20 and the second longitudinal guide rail group 30 at the same time (but attention should be paid to prevent collision interference), so that the elevator system 100 can meet the needs of different passengers at the same time, and the service performance of the elevator system 100 is improved.
[0064] In the above scheme, it is known that the car 80 is capable of moving in the horizontal direction on the first and second lateral rail groups 40 and 50, and then switching to move on the first and second longitudinal rail groups 20 and 30 to continue vertical movement, or moving in the vertical direction on the first and second longitudinal rail groups 20 and 30, and then switching to move on the first and second lateral rail groups 40 and 50 to continue horizontal movement, while the first and second longitudinal rails 21 and 22 should be vertically arranged with the first and second lateral rails 41 and 42, and the third and fourth longitudinal rails 31 and 32 should be vertically arranged with the third and fourth lateral rails 51 and 52, so it is necessary to provide a turning device capable of assisting the car 80 to flexibly switch between the horizontal and vertical directions to ensure reliable operation of the car 80.
[0065] Please continue to refer to Figure 3 and Figure 6 , specifically, in some embodiments, the elevator system 100 further comprises a mover rotating drive motor 90d, a driving gear 90e, a driven gear 90f and a guide rail rotating disc 90g, the mover rotating drive motor 90d is arranged on the top and bottom cross beams 81 and 82, the driving gear 90e is connected with the mover rotating drive motor 90d, the driven gear 90f is rotatably arranged at the end of the top and bottom cross beams 81 and 82 and connected with the cross beam mover 90b, and the driven gear 90f is engaged with the driving gear 90e.
[0066] The guide rail rotating disc 90g is provided with a matching through hole 91g, the hole wall of the matching through hole 91g is structurally adapted to the outer contour of the cross beam mover 90b, so that the guide rail rotating disc 90g can be driven to rotate by the cross beam mover 90b, so that the top and bottom mover assemblies 83 and 84 can move and switch between the longitudinal guide grooves 90 and the lateral guide grooves 90a through the guide rail rotating disc 90g.
[0067] The diameter of the matching through hole 91g is adapted to the width of the longitudinal guide groove 90 and the width of the lateral guide groove 90a, when the car 80 moves in the horizontal direction along the lateral guide groove 90a and reaches the connection between the first and second lateral rail groups 40 and 50 and the first and second longitudinal rail groups 20 and 30, since the matching through hole 91g is in alignment with the lateral guide groove 90a, the top and bottom mover assemblies 83 and 84 will enter the matching through hole 91g, then the mover rotating drive motor 90d is started to drive the driving gear 90e to rotate the driven gear 90f, the driven gear 90f in turn can synchronously drive the guide rail rotating disc 90g to rotate 90°, so that the matching through hole 91g switches to be in alignment with the longitudinal guide groove 90, in this way, the top and bottom mover assemblies 83 and 84 can enter the longitudinal guide groove 90, so that the car 80 can switch to move in the vertical direction.
[0068] In the present application, the implementation of the car 80 running reversal can be at least as follows:
[0069] Please continue to refer to Figure 2 , Figure 3 and Figure 4 , the first is through the top mover assembly 83 and the bottom mover assembly 84 drive reversal of the way, suitable for car 80 on the non-cyclic path. Specifically, in one embodiment, the guide rail rotating disc 90g includes a connecting sheet metal 92g, a rotating disc body 93g, an electromagnetic lock 94g and a return spring 95g, the connecting sheet metal 92g is arranged on the first longitudinal guide rail group 20 and the second longitudinal guide rail group 30, the rotating disc body 93g is rotatably arranged on the connecting sheet metal 92g and located in the cavity at the connection of the first longitudinal guide rail group 20 and the first transverse guide rail group 40 and the second longitudinal guide rail group 30 and the second transverse guide rail group 50, the first transverse guide rail group 40 and the second transverse guide rail group 50 are provided with lock holes, the electromagnetic lock 94g is arranged on the rotating disc body 93g and cooperates with the lock holes to lock or unlock, one end of the return spring 95g is arranged on the first longitudinal guide rail group 20 and the second longitudinal guide rail group 30 through a fixed block, and the other end of the return spring 95g is arranged on the rotating disc body 93g through a limiting block.
[0070] Please continue to refer to Figure 2 and Figure 6 , further, the elevator system 100 further comprises a telescopic drive device 100a and an auxiliary drive mover 100b, the telescopic drive device 100a is arranged on the top cross beam 81 and / or the bottom cross beam 82, the auxiliary drive mover 100b is connected with the telescopic drive device 100a, the auxiliary drive mover 100b can be driven to extend into the longitudinal guide groove 90 by the telescopic drive device 100a, or the auxiliary drive mover 100b can be driven to retract out of the longitudinal guide groove 90 by the telescopic drive device 100a; wherein, the auxiliary drive mover 100b comprises an auxiliary drive coil 110b, the auxiliary drive coil 110b can cooperate with the longitudinal stator permanent magnet 60 in magnetic induction.
[0071] When the beam mover 90b runs vertically to the center of the guide rail rotating disc 90g, the car 80 stops running. The auxiliary drive mover 100b extends into the longitudinal guide slot 90 under the drive of the telescopic drive device 100a and is electrified to give the car 80 a magnetic force of the same size as the weight of the car 80 in the opposite direction, so as to support the car 80. Then the mover coil 90c on the beam mover 90b is de-energized and no magnetic force is generated. The mover rotating drive motor 90d on the top beam 81 and the bottom beam 82 drives the top mover assembly 83 and the bottom mover assembly 84 to rotate through the speed reduction cooperation of the size gears (i.e. the meshing driving gear 90e and the driven gear 90f), so as to drive the guide rail rotating disc 90g to rotate against the elastic force of the rotating disc return spring 95g. When the guide rail rotating disc 90g rotates by 90 degrees, the electromagnetic lock 94g is electrified. The electromagnetic lock 94g is composed of a lock rod and a spring. Under the electromagnetic force, the lock rod overcomes the spring force and is inserted into the lock hole to be locked (on the contrary, the lock hole can also be locked when de-energized). The top mover assembly 83 and the bottom mover assembly 84 continue to rotate by a small angle after rotating by 90 degrees, so that the guide rail rotating disc 90g completes 90-degree rotation (the electromagnetic lock 94g locks the lock hole), and the mover rotating drive motor 90d is reversely driven to rotate by a small angle, so as to restore the angle of 90 degrees with the original running direction (the beam mover 90b is physically engaged with the guide rail groove, drives the guide rail rotating disc 90g, and the rotation angle of the beam mover 90b is slightly larger than that of the guide rail rotating disc 90g, which needs to be rotated back). After the auxiliary drive mover 100b is retracted from the projection surface of the car 80, the car 80 can run horizontally.
[0072] Conversely, when the car 80 changes the running direction to return (the horizontal running is changed to vertical running), the car 80 stops running when it runs horizontally to the center of the guide rail rotating disc 90g. The auxiliary drive mover 100b extends into the longitudinal guide slot 90 and is electrified to form a magnetic coupling with the longitudinal stator permanent magnet, so as to give the car 80 a magnetic force of the same size as the weight of the car 80 in the opposite direction. Then the mover coil 90c on the beam mover 90b is de-energized and no magnetic force is generated. At this time, the electromagnetic lock 94g is de-energized, and the mover rotating drive motor 90d drives the rotating mover 90 degrees in the opposite direction through the speed reduction cooperation of the size gears (i.e. the meshing driving gear 90e and the driven gear 90f). The guide rail rotating disc 90g is rotated clockwise under the restoring force of the return spring 95g after the electromagnetic lock 94g is unlocked (after de-energized). When the limit block hits the right edge of the connecting sheet metal 92g (also serving as a limit), the guide rail rotating disc 90g is just restored to the vertical running direction. Then the change of the running direction of the car 80 from horizontal to vertical is completed. This mode is suitable for the running of the car 80 on a non-circulating path.
[0073] Please continue to see Figure 2 and Figure 5, the second is to drive the beam mover 90b to rotate and turn by the guide rail rotating disc 90g. This scheme is suitable for the operation of the car 80 on the circulating path. Specifically, in one embodiment, the guide rail rotating disc 90g comprises a rotating motor 96g, a drive gear 97g, an intermediate gear 98g, a rotating disc gear 99g, a rotating disc body 93g and an electromagnetic lock 94g. The rotating disc body 93g is rotatably arranged in the connecting cavity of the connecting plate 92g at the joint of the first longitudinal guide rail group 20 and the first transverse guide rail group 40 and the second longitudinal guide rail group 30 and the second transverse guide rail group 50. The rotating disc gear 99g is arranged on the outer periphery of the rotating disc body 93g. The rotating motor 96g is arranged on the first transverse guide rail group 40 and the second transverse guide rail group 50 and connected with the drive gear 97g. The intermediate gear 98g is arranged on the first longitudinal guide rail group 20 and the second longitudinal guide rail group 30 and simultaneously engaged with the drive gear 97g and the rotating disc gear 99g. The rotating disc body 93g is provided with a lock hole. The electromagnetic lock 94g is arranged on the end surface of the beam mover 90b and can be locked or unlocked with the lock hole.
[0074] When the beam mover 90b vertically operates to the center of the guide rail rotating disc 90g, the car 80 stops operating. The auxiliary drive mover 100b gives the magnetic force in the opposite direction of the weight of the car 80. Then the mover coil 90c on the beam mover 90b loses power and does not generate magnetic force. The electromagnetic lock 94g on the end surface of the beam mover 90b loses power. The locking rod of the electromagnetic lock 94g extends under the action of the spring force and locks the lock hole of the guide rail rotating disc 90g. The motor drives the drive gear 97g to rotate. The drive gear 97g drives the rotating disc body 93g through the intermediate gear 98g. The rotating disc body 93g drives the beam mover 90b to rotate synchronously through the locking rod of the electromagnetic lock 94g. After rotating 90 degrees, the motor stops. Then the electromagnetic lock 94g is powered to be unlocked. After the auxiliary drive mover 100b retracts from the projection surface of the car 80, the car 80 can operate horizontally. Conversely, when the car 80 changes the operating direction to return (the horizontal operation changes to the vertical operation), the car 80 horizontally operates to the center of the guide rail rotating disc 90g and stops operating. The electromagnetic lock 94g on the end surface of the beam mover 90b loses power and locks the lock hole of the guide rail rotating disc 90g. The auxiliary drive mover 100b extends into the longitudinal guide slot 90. The electromagnetic coupling between the magnetic field of the auxiliary drive mover 100b and the longitudinal stator permanent magnet is formed by power supply. The magnetic force in the opposite direction of the weight of the car 80 is given. Then the mover coil 90c on the beam mover 90b loses power and the magnetic force disappears. The rotating motor 96g drives the guide rail rotating disc 90g to rotate through the three gears engaged with each other. The beam mover 90b is synchronously driven to rotate through the locking rod of the electromagnetic lock 94g. After rotating 90 degrees, the rotating motor 96g stops. Then the electromagnetic lock 94g is unlocked. The mover coil 90c on the beam mover 90b is powered again. The car 80 changes to vertical operation.
[0075] Please continue to refer to Figure 6In any of the above embodiments, the telescopic drive device 100a comprises a telescopic motor 110a, a telescopic gear 120a, a linear bearing 130a and a rack 140a. The telescopic motor 110a is arranged on the top cross beam 81 or the bottom cross beam 82 and connected with the telescopic gear 120a. The telescopic gear 120a is engaged with the rack 140a. The linear bearing 130a is arranged on the top cross beam 81 or the bottom cross beam 82 and slidingly installed with the rack 140a. Alternatively, as shown in Figure 7 The telescopic drive device 100a is configured as a driver capable of directly outputting telescopic linear force. The telescopic drive device 100a has simple structure, simple principle of outputting linear telescopic force and reliable operation.
[0076] When the required power for vertical operation of the car 80 (the car 80 loaded with heavy objects is operated according to the set S-shaped speed curve) exceeds the corresponding motor driving power of the two pairs of top motor assemblies 83 and bottom motor assemblies 84 of the top cross beam 81 and the bottom cross beam 82, or the car 80 needs to be accelerated, the auxiliary driving motor 100b is driven to extend into the magnetic circuit of the " " type guide rail (adjust its output power), forming a new set of linear motors, which can increase the vertical operation driving power of the car 80.
[0077] When the car 80 is changed from longitudinal operation to transverse operation, the auxiliary driving motor 100b is automatically retracted into the projection range of the car 80. At this time, the weight of the car 80 is overcome by the magnetic coupling force between the motor coil 90c on the cross beam motor 90b and the transverse stator permanent magnet 70. The magnetic coupling force is specifically the repulsive force generated by the motor coil 90c and the permanent magnet at the lower part of the transverse guide rail, and the attractive force generated by the motor coil 90c on the other side and the permanent magnet at the upper part of the transverse guide rail. Further, in overcoming the gravity of the car 80, the coils on the three faces of the cross beam motor 90b relative to the transverse guide rail also generate horizontal magnetic coupling force, so that the car 80 operates in the set horizontal direction.
[0078] In addition, in some embodiments, the car 80 further comprises a car body 85 for loading the top cross beam 81 and the bottom cross beam 82. At least two car doors 86 are arranged on the adjacent and / or opposite sides of the car body 85. In this way, the needs of the building 200 to set the hall door 210 on different facades can be met.
[0079] Please continue to refer to Figure 6, the elevator system 100 further comprises a Hall sensor 100c arranged on the top of the car 80 or near the top of the side of the car 80. The top cross beam 81 and the bottom cross beam 82 are provided with four linear motor movers, and each mover is provided with at least one set of mover coils 90c on at least one side. Preferably, mover coils 90c are arranged on three sides, and are matched with the three sides inside the guide groove. Each side of the mover coils 90c can be arranged as an even number N groups in the longitudinal direction, and the same length of permanent magnets in the longitudinal guide groove 90 and the transverse guide groove 90a are arranged as N-1 groups, and all magnetic circuits are arranged at intervals, including the longitudinal guide magnetic circuit, the transverse guide magnetic circuit, and the bottom magnetic circuit in the guide rotating disc 90g. In particular, the permanent magnets on both sides of the guide rotating disc 90g are arranged as one group (with a difference in interval from the guide magnetic circuit, as a flag bit of the magnetic circuit node), which can enable the cross beam mover 90b to identify the position of the guide magnetic circuit.
[0080] The Hall sensor 100c arranged on the top of the car 80 can detect the position of the permanent magnet inside the longitudinal magnetic circuit in real time. The vertical distance between the Hall sensor 100c and the center point of the cross beam mover 90b is L. Specifically, after the Hall sensor 100c detects the flag bit signal of a magnetic circuit node: running downward by L distance; running upward by (the distance between the upper and lower cross beams of the car 80 - L), at which time the center of the cross beam mover 90b coincides with the center of the guide rotating disc 90g. The conversion action of the running route of the car 80 can be performed.
