Description

Technical Field

[0001] The present application relates to the technical field of elevators, and in particular to an elevator system. Background Art

[0002] Nowadays, elevator systems are widely used in various buildings to automatically transport passengers from the starting floor to the target floor, which not only reduces the fatigue caused by climbing stairs, but also greatly improves the traffic efficiency. The commonly used elevator system is usually a traction elevator, which installs a traction machine at the top of the shaft, and the traction machine is connected to the car through the traction rope, pulling or releasing the car to make the car move 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, resulting in a long traction rope, which is prone to be unable to bear the weight of itself, the car, and the counterweight and is pulled and broken. Therefore, a new type of elevator system that uses a linear motor to drive the car to move in the shaft has emerged in the industry. Its working principle is: by installing a mover coil on the car and a stator on the track (or a stator on the car and a mover coil 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, due to structural design defects, the existing elevator system that uses a linear motor to drive the car will cause a large eccentric load during the car's suspension and operation, resulting in the car's inability to run smoothly, affecting the comfort and experience of riding the elevator. Summary of the invention

[0004] Based on this, it is necessary to provide an elevator system to address the problem that the eccentric load affects the smooth operation of the car, resulting in poor riding comfort and experience.

[0005] The present application provides an elevator system, comprising:

[0006] Well;

[0007] A first longitudinal guide rail group and a second longitudinal guide rail group are arranged opposite to each other at an interval, and the first longitudinal guide rail group and the second longitudinal guide rail group are both extended along the vertical direction of the hoistway;

[0008] A first transverse guide rail group and a second transverse guide rail group are arranged opposite to each other at an interval, wherein the first transverse guide rail group and the second transverse guide rail group are both extended along the horizontal direction of the shaft, and the first transverse guide rail group is arranged on the first longitudinal guide rail group, and the second transverse guide rail group is arranged on the second longitudinal guide rail group;

[0009] Longitudinal stator permanent magnets, the longitudinal stator permanent magnets are arranged on the first longitudinal guide rail group and the second longitudinal guide rail group;

When the car moves up and down in the vertical direction in the hoistway along the first longitudinal guide rail group and the second longitudinal guide rail group, or moves back and forth in the horizontal direction in the hoistway along the first transverse guide rail group and the second transverse guide rail group, the top mover assemblies and the bottom mover assemblies arranged symmetrically on both sides are moved up and down in the vertical direction in the hoistway along the first transverse guide rail group and the second transverse guide rail group. The component can generate a balanced magnetic field force with the longitudinal stator permanent magnet or the transverse stator permanent magnet, thereby ensuring that the magnetic coupling effect tends to be consistent, ensuring that the position of the car remains stable during vertical or horizontal movement, or even if there is an overload on one side of the car, the car can be corrected to a stable posture by coordinating the magnetic field force generated between the top mover assembly and the bottom mover assembly on both sides of the car and the longitudinal stator permanent magnet or the transverse stator permanent magnet, eliminating the overload force and its negative impact, ensuring that the car can run smoothly in the shaft, and improving the comfort and experience of riding the elevator.

[0046] See also Figure 1 , Figure 2 and Figure 3 , an elevator system 100 shown in an embodiment of the present application, includes a hoistway 10, a first longitudinal guide rail group 20 and a second longitudinal guide rail group 30 arranged opposite to each other at intervals, a first transverse guide rail group 40 and a second transverse guide rail group 50 arranged opposite to each other at intervals, 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 group 20 and the second longitudinal guide rail group 30 are arranged relative to each other at intervals in the width direction of the shaft 10, and the first transverse guide rail group 40 and the second transverse guide rail group 50 are arranged relative to each other at intervals 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 both extended along the vertical direction of the hoistway 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 hoistway 10.

[0049] The first transverse guide rail group 40 and the second transverse guide rail group 50 are both extended along the horizontal direction of the hoistway 10, and the first transverse guide rail group 40 is arranged on the first longitudinal guide rail group 20, and the second transverse guide rail group 50 is arranged on the second longitudinal guide rail group 30. It can be understood that the first transverse guide rail group 40 and the second transverse guide rail group 50 are used to provide the support and guidance required for the horizontal movement of the car 80 in the hoistway 10.

[0050] Please continue reading Figure 3 and Figure 6 The longitudinal stator permanent magnet 60 is arranged on the first longitudinal guide rail group 20 and the second longitudinal guide rail group 30; the transverse stator permanent magnet 70 is arranged on the first transverse guide rail group 40 and the second transverse guide rail group 50; the car 80 is arranged in the hoistway 10, and the car 80 includes a top crossbeam 81 arranged at the top and a bottom crossbeam 82 arranged at the bottom, and top mover assemblies 83 are arranged at opposite ends of the top crossbeam 81, and the top mover assembly 83 can cooperate with the longitudinal stator permanent magnet 60 or the transverse stator permanent magnet 70 by magnetic induction, and bottom mover assemblies 84 are arranged at opposite ends of the bottom crossbeam 82, and the bottom mover assembly 84 can cooperate with the longitudinal stator permanent magnet 60 or the transverse stator permanent magnet 70 by magnetic induction.

[0051] It can be understood that the top mover assembly 83 and the bottom mover assembly 84 are connected to the elevator central control cabinet via cables or wirelessly, and the elevator central control cabinet regulates and controls the power on and off, input current, etc. of the top mover assembly 83 and the bottom mover assembly 84.

[0052] When the top mover assembly 83 and the bottom mover assembly 84 are connected to current, a magnetic field force is generated. When the magnetic field force is magnetically coupled with the longitudinal stator permanent magnet 60, the generated magnetic driving force can drive the car 80 to move up and down in the shaft 10 along the first longitudinal guide rail group 20 and the second longitudinal guide rail group 30, or, when the magnetic field force is magnetically coupled with the transverse stator permanent magnet 70, the generated magnetic driving force can drive the car 80 to move horizontally in the shaft 10 along the first transverse guide rail group 40 and the second transverse guide rail group 50.

[0053] In summary, the implementation of the technical solution of this embodiment will have the following beneficial effects: in the elevator system 100 of the above solution, by simultaneously arranging the first longitudinal guide rail group 20 and the second longitudinal guide rail group 30 extending in the vertical direction, and the first transverse guide rail group 40 and the second transverse guide rail group 50 extending in the horizontal direction in the hoistway 10, and simultaneously installing the top mover assembly 83 at the opposite ends of the top crossbeam 81 of the car 80, and installing the bottom mover assembly 84 at the opposite ends of the bottom crossbeam 82, when the car 80 moves up and down in the vertical direction in the hoistway 10 along the first longitudinal guide rail group 20 and the second longitudinal guide rail group 30, or moves back and forth in the horizontal direction in the hoistway 10 along the first transverse guide rail group 40 and the second transverse guide rail group 42, the symmetrical arrangement The top mover assembly 83 and the bottom mover assembly 84 on both sides can generate a balanced magnetic field force with 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 to avoid unbalanced loading problems. 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, thereby eliminating the unbalanced load force and its negative impact, ensuring that the car 80 can run smoothly in the shaft 10, and improving the comfort and experience of riding the elevator.

[0054] Preferably, the top cross beam 81 and the bottom cross beam 82 are installed on the center line of the vertical cross section of the car 80, so as to eliminate the eccentric load of the car 80 as much as possible from the physical structure.

[0055] Please continue reading Figure 2 Specifically, based on the above embodiment, the first longitudinal guide rail group 20 includes a first longitudinal guide rail 21 and a second longitudinal guide rail 22 that are horizontally spaced and relatively arranged, and the first transverse guide rail group 40 includes a first transverse guide rail 41 and a second transverse guide rail 42 that are vertically spaced and relatively arranged, and both ends of the first transverse guide rail 41 and both 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 in a one-to-one correspondence.

[0056] The second longitudinal guide rail group 30 includes a third longitudinal guide rail 31 and a fourth longitudinal guide rail 32 which are arranged opposite to each other at an interval, and the second transverse guide rail group 50 includes a third transverse guide rail 51 and a fourth transverse guide rail 52 which are arranged opposite to each other at an interval vertically, and both ends of the third transverse guide rail 51 and both ends of the fourth transverse guide rail 52 are respectively connected to the third longitudinal guide rail 31 and the fourth longitudinal guide rail 32 in a one-to-one correspondence.

[0057] Through the above structural design, on the one hand, the first longitudinal guide rail 21 and the second longitudinal guide rail 22 are supported by the side wall of the well 10 to achieve their own stable installation. At the same time, the first transverse guide rail 41 and the second transverse guide rail 42 are fixed by loading, so that the first transverse guide rail 41 and the second transverse guide rail 42 are stably installed. Similarly, the third longitudinal guide rail 31 and the fourth longitudinal guide rail 32 are supported by the side wall of the well 10 to achieve their own stable installation. At the same time, the third transverse guide rail 51 and the fourth transverse guide rail 52 are fixed by loading, so that the third transverse guide rail 51 and the fourth transverse guide rail 52 are stably installed. Stable installation; on the other hand, the two top mover assemblies 83 at the opposite ends of the top crossbeam 81 are respectively installed and cooperated with the first transverse guide rail 41 and the third transverse guide rail 51 (or the first longitudinal guide rail 21 and the third longitudinal guide rail 31), and the two bottom mover assemblies 84 at the opposite ends of the bottom crossbeam 82 are respectively installed and cooperated with the second transverse guide rail 42 and the fourth transverse guide rail 52 (the second longitudinal guide rail 22 and the fourth longitudinal guide rail 32), so that the opposite sides of the car 80 are synchronously and evenly supported, avoiding the generation of eccentric load force of the car 80 and ensuring the smooth operation of the car 80.

[0058] Please continue reading Figure 3 and Figure 6 In some other embodiments, the opposite sides of the first longitudinal guide rail group 20 and the second longitudinal guide rail group 30 are both recessed with longitudinal guide grooves 90, and the longitudinal stator permanent magnets 60 are arranged in the longitudinal guide grooves 90 and cooperate with the magnetic induction gaps of the top mover assembly 83 and the bottom mover assembly 84; the opposite sides of the first transverse guide rail group 40 and the second transverse guide rail group 50 are both recessed with transverse guide grooves 90a, and the transverse stator permanent magnets 70 are arranged in the transverse guide grooves 90a and cooperate with the magnetic induction gaps of the top mover assembly 83 and the bottom mover assembly 84.

[0059] On the one hand, the longitudinal stator permanent magnet 60 and the transverse stator permanent magnet 70 are placed in the longitudinal guide groove 90 and the transverse guide groove 90a, which improves the installation reliability of the longitudinal stator permanent magnet 60 and the transverse stator permanent magnet 70; on the other hand, the top mover assembly 83 and the bottom mover assembly 84 need to extend into the longitudinal guide groove 90 and the transverse guide groove 90a so as to be opposite to the front of the longitudinal stator permanent magnet 60 and the transverse stator permanent magnet 70 to ensure the effect of the magnetic field. Each guide rail can effectively suppress the overflow loss of magnetic flux lines and improve the driving efficiency of the car 80.

[0060] Please continue reading Figure 2 , Figure 3 and Figure 6 Furthermore, in this embodiment, the longitudinal guide groove 90 and the transverse guide groove 90a are both configured as " " type, longitudinal stator permanent magnets 60 are arranged on the three sides of the longitudinal guide groove 90, and transverse stator permanent magnets 70 are arranged on the three sides of the transverse guide groove 90a; the top mover assembly 83 and the bottom mover assembly 84 both include a crossbeam mover 90b and three mover coils 90c, and the three mover coils 90c are respectively arranged on three different sides of the crossbeam 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 in a one-to-one correspondence with the magnetic induction gap.

[0061] By setting a larger number of paired movable coils 90c and longitudinal stator permanent magnets 60 (vertical movement) or a larger number of paired movable coils 90c and transverse stator permanent magnets 70 (horizontal movement), the driving force for the movement of the car 80 can be enhanced to meet the power requirements for normal operation of the car 80 under heavy load conditions.

[0062] It is necessary to explain 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 extended integrally along the longitudinal guide groove 90, or can be arranged in a plurality of separate pieces at intervals and extended in sequence; 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 extended integrally along the transverse guide groove 90a, or can be arranged in a plurality of separate pieces at intervals and extended in sequence.

[0063] It is necessary to explain that in the present scheme, there may be more than one pair of the first transverse guide rail group 40 and the second transverse guide rail group 50. For example, at least two pairs of the first transverse guide rail group 40 and the second transverse guide rail group 50 are installed at intervals 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 floor hall door 210 respectively. Based on this, there may be more than one car 80 in the present scheme. Specifically, each group of the first transverse guide rail group 40 and the second transverse guide rail group 50 corresponds to one car 80, and each car 80 moves horizontally on its own group of the first transverse guide rail group 40 and the 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 care should be taken to prevent collision and interference problems), so that the elevator system 100 can meet the needs of different passengers at the same time and improve the service performance of the elevator system 100.

[0064] It can be seen from the above scheme that the car 80 is able to move in the horizontal direction on the first transverse guide group 40 and the second transverse guide group 50, and then switch to the first longitudinal guide group 20 and the second longitudinal guide group 30 to continue moving in the vertical direction, or after moving in the vertical direction on the first longitudinal guide group 20 and the second longitudinal guide group 30, switch to the first transverse guide group 40 and the second transverse guide group 50 to continue moving in the horizontal direction, and the first longitudinal guide 21, the second longitudinal guide 22 and the first transverse guide 41 and the second transverse guide 42 should be vertically arranged, and the third longitudinal guide 31, the fourth longitudinal guide 32 and the third transverse guide 51 and the fourth transverse guide 52 should be vertically arranged. Therefore, it is necessary to provide a steering device that can assist the car 80 in flexibly switching between the horizontal and vertical directions to ensure the reliable operation of the car 80.

[0065] Please continue reading Figure 3 and Figure 6 Specifically, in some embodiments, the elevator system 100 also includes a mover rotation drive motor 90d, a driving gear 90e, a driven gear 90f and a guide rail rotating disk 90g. The mover rotation drive motor 90d is arranged on the top beam 81 and the bottom beam 82, the driving gear 90e is connected to the mover rotation drive motor 90d, the driven gear 90f is rotatably arranged at the ends of the top beam 81 and the bottom beam 82 and is connected to the beam mover 90b, and the driven gear 90f is meshed with the driving gear 90e.

[0066] The guide rail rotating disk 90g is provided with a matching through hole 91g, and the hole wall of the matching through hole 91g is structurally adapted to the outer contour of the crossbeam mover 90b, so that the guide rail rotating disk 90g can be driven by the crossbeam mover 90b to rotate, so that the top mover assembly 83 and the bottom mover assembly 84 can move and switch between the longitudinal guide groove 90 and the transverse guide groove 90a via the guide rail rotating disk 90g.

[0067] The diameter of the matching through hole 91g is compatible with the width of the longitudinal guide groove 90 and the width of the transverse guide groove 90a. When the car 80 moves along the transverse guide groove 90a in the horizontal direction and reaches the connection between the first transverse guide rail group 40 and the second transverse guide rail group 50 and the first longitudinal guide rail group 20 and the second longitudinal guide rail group 30, since the matching through hole 91g is aligned and connected with the transverse guide groove 90a, the top mover assembly 83 and the bottom mover assembly 84 will enter the matching through hole 91g, and then the mover rotation drive motor 90d is started, driving the driving gear 90e to drive the driven gear 90f to rotate, and the driven gear 90f can then synchronously drive the guide rail rotating disk 90g to rotate 90°, so that the matching through hole 91g is switched to be aligned and connected with the longitudinal guide groove 90. In this way, the top mover assembly 83 and the bottom mover assembly 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, there are at least two implementation schemes for reversing the operation of the car 80:

[0069] Please continue reading Figure 2 , Figure 3 and Figure 4 The first one is a method of driving the reversing by the top mover assembly 83 and the bottom mover assembly 84, which is suitable for the car 80 to run on a non-circulating path. Specifically, in one embodiment, the guide rail rotating disk 90g includes a connecting sheet metal 92g, a turntable 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 turntable body 93g is rotatably arranged on the connecting sheet metal 92g and is located in a connection cavity between 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 a locking hole. The electromagnetic lock 94g is arranged on the turntable body 93g and cooperates with the locking hole 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 fixing block, and the other end of the return spring 95g is arranged on the turntable body 93g through a limit block.

[0070] Please continue reading Figure 2 and Figure 6 Further, the elevator system 100 also includes a telescopic drive device 100a and an auxiliary drive mover 100b, the telescopic drive device 100a is arranged on the top beam 81 and / or the bottom beam 82, the auxiliary drive mover 100b is connected to the telescopic drive device 100a, the auxiliary drive mover 100b can be driven by the telescopic drive device 100a to extend into the longitudinal guide groove 90, or the auxiliary drive mover 100b can be driven by the telescopic drive device 100a to retract to exit the longitudinal guide groove 90; wherein the auxiliary drive mover 100b includes an auxiliary drive coil 110b, and the auxiliary drive coil 110b can cooperate with the magnetic induction of the longitudinal stator permanent magnet 60.

[0071] When the crossbeam mover 90b moves vertically to the center of the guide rail rotating disk 90g, the car 80 stops running, and the auxiliary drive mover 100b, driven by the telescopic drive device 100a, extends into the longitudinal guide groove 90 and is energized to provide a reverse magnetic force equal to the weight of the car 80, thereby supporting the car 80. Then, the mover coil 90c on the crossbeam mover 90b loses power and generates no magnetic force. The mover rotation drive motor 90d on the top crossbeam 81 and the bottom crossbeam 82 rotates the top mover assembly 83 and the bottom mover assembly 84 through the reduction cooperation of the large and small gears (i.e., the meshing driving gear 90e and the driven gear 90f), thereby driving the guide rail rotating disk 90g to rotate to overcome the elastic force of the turntable return spring 95g. When the guide rail rotating disk 90g rotates 90 degrees, the electromagnetic lock 94g is energized. The electromagnetic lock 94g consists of a locking rod and a spring. Under the action of the electromagnetic force, the locking rod overcomes the spring force and is inserted into the lock hole to lock it (conversely, it can also be locked when the power is off). After rotating 90 degrees, the top mover assembly 83 and the bottom mover assembly 84 continue to rotate a small angle, so that the guide rail rotating disk 90g completes a 90-degree rotation (the electromagnetic lock 94g locks the lock hole), and the mover rotation drive motor 90d then drives the small angle in the reverse direction to restore the angle of 90 degrees with the original running direction (the crossbeam mover 90b physically fits with the guide rail groove, driving the guide rail rotating disk 90g. The rotation angle of the crossbeam mover 90b is slightly larger than that of the guide rail rotating disk 90g, and needs to be rotated back). After the auxiliary drive mover 100b is retracted to the projection surface of the car 80, the car 80 can run horizontally;

[0072] On the contrary, when the car 80 changes its running direction and returns (transverse running is changed to vertical running), the car 80 stops running when it runs horizontally to the center of the guide rail rotating disk 90g. The auxiliary driving mover 100b extends into the longitudinal guide groove 90, and is energized to form a magnetic coupling between its magnetic field and the longitudinal stator permanent magnet, giving a reverse magnetic force equal to the weight of the car 80. Then the mover coil 90c on the crossbeam mover 90b loses power and does not generate magnetic force. At this time, the electromagnetic lock 94g is powered off, and the mover rotation drive motor 90d drives the mover to rotate 90 degrees in the opposite direction through the reduction of the large and small gears (i.e., the meshing driving gear 90e and the driven gear 90f). The guide rail rotating disk 90g rotates clockwise under the restoring force of the return spring 95g after the electromagnetic lock 94g is unlocked (power off). When the limit block touches the right edge of the connecting sheet metal 92g (also serves as a limit), the guide rail rotating disk 90g just returns to the vertical running direction. And then complete the conversion of changing the running direction of the car 80 from horizontal to vertical. This mode is suitable for the operation of the car 80 on the non-circulating path.

[0073] Please continue reading Figure 2 and Figure 5The second method is to drive the crossbeam mover 90b to rotate and turn by the guide rail rotating disk 90g. This solution is suitable for the operation of the car 80 on the circulation path. Specifically, in one embodiment, the guide rail rotating disk 90g includes a rotating motor 96g, a driving gear 97g, an intermediate gear 98g, a turntable gear 99g, a turntable body 93g and an electromagnetic lock 94g. The turntable body 93g is rotatably arranged on the connecting sheet metal 92g and is located in a cavity at the connection between the first longitudinal guide group 20 and the first transverse guide group 40 and the second longitudinal guide group 30 and the second transverse guide group 50. The turntable gear 99g is arranged on the outer periphery of the turntable body 93g. The rotating motor 96g is arranged on the first transverse guide group 40 and the second transverse guide group 50 and is connected to the driving gear 97g. The intermediate gear 98g is arranged on the first longitudinal guide group 20 and the second longitudinal guide group 30, and the intermediate gear 98g is meshed with the driving gear 97g and the turntable gear 99g at the same time. The turntable body 93g is provided with a locking hole. The electromagnetic lock 94g is arranged on the end face of the crossbeam mover 90b and can be locked or unlocked with the locking hole.

[0074] When the cross beam mover 90b moves vertically to the center of the guide rail rotating disk 90g, the car 80 stops running, and the auxiliary drive mover 100b gives the reverse magnetic force of the weight of the car 80. Then the mover coil 90c on the cross beam mover 90b loses power and no magnetic force is generated. The electromagnetic lock 94g on the end face of the cross beam mover 90b loses power, and the lock rod of the electromagnetic lock 94g extends under the action of the spring force to lock the lock hole of the guide rail rotating disk 90g. The motor drives the driving gear 97g to rotate, and the driving gear 97g drives the turntable body 93g through the intermediate gear 98g. The turntable body 93g then drives the beam mover 90b to rotate synchronously through the locking rod of the electromagnetic lock 94g. After rotating 90 degrees, the motor stops, and then the electromagnetic lock 94g is powered on and unlocked. After the auxiliary driving mover 100b is retracted to the projection surface of the car 80, the car 80 can run horizontally; conversely, when the car 80 changes its running direction and returns (horizontal operation is changed to vertical operation), when the car 80 runs horizontally to the center of the guide rail rotating disk 90g, the car 80 stops running, and the electromagnetic lock 94g on the end face of the beam mover 90b loses power, locking the lock hole of the guide rail rotating disk 90g. The auxiliary drive mover 100b extends into the longitudinal guide groove 90, and is energized to form a magnetic coupling between its magnetic field and the longitudinal stator permanent magnet, giving a reverse magnetic force equal to the weight of the car 80. Then, the mover coil 90c on the crossbeam mover 90b loses power, causing the magnetic force to disappear. The rotating motor 96g drives the guide rail rotating disk 90g to rotate through three meshing gears, and synchronously drives the crossbeam mover 90b to rotate synchronously through the lock rod of the electromagnetic lock 94g. After rotating 90 degrees, the rotating motor 96g stops, and then the electromagnetic lock 94g is unlocked, and the mover coil 90c on the crossbeam mover 90b resumes power supply, and the car 80 turns to vertical operation.

[0075] Please continue reading Figure 6On the basis of any of the above embodiments, the telescopic drive device 100a includes 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 beam 81 or the bottom beam 82 and connected to the telescopic gear 120a, the telescopic gear 120a is meshed with the rack 140a, the linear bearing 130a is arranged on the top beam 81 or the bottom beam 82 and is slidably mounted and matched with the rack 140a; or Figure 7 As shown, the telescopic drive device 100a is configured as a driver capable of directly outputting telescopic linear power. The telescopic drive device 100a has a simple structure, a simple principle for outputting linear telescopic power, and works reliably.

[0076] When the power required for the vertical operation of the car 80 (the car 80 is loaded with heavy objects and runs according to the set S-shaped speed curve) exceeds the corresponding drive power of the two pairs of top mover assemblies 83 and bottom mover assemblies 84 of the top crossbeam 81 and the bottom crossbeam 82, or when the car 80 needs to speed up, the auxiliary drive mover 100b is driven to extend and enter the " "-type guide rail magnetic circuit (adjust its output power), forming a new group of linear motors, which can increase the vertical operation driving power of the car 80.

[0077] When the car 80 changes from longitudinal operation to transverse operation, the auxiliary drive mover 100b automatically retracts 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 mover coil 90c on the crossbeam mover 90b and the transverse stator permanent magnet 70. The magnetic coupling force is specifically that the mover coil 90c generates a repulsive force with the permanent magnet at the bottom of the transverse guide rail, and the mover coil 90c on the other side generates an attractive force with the permanent magnet at the top of the transverse guide rail. Furthermore, when overcoming the gravity of the car 80, the coils on the three surfaces of the crossbeam mover 90b will also generate horizontal magnetic coupling forces relative to the transverse guide rail, causing the car 80 to run in the set horizontal direction.

[0078] In addition, in some other embodiments, the car 80 further includes a car body 85 for loading the top cross beam 81 and the bottom cross beam 82, and at least two car doors 86 are arranged on adjacent and / or opposite sides of the car body 85. This can meet the need of arranging hall doors 210 on different facades of the building 200.

[0079] Please continue reading Figure 6, the elevator system 100 also includes a Hall sensor 100c, which is arranged at the top or side of the car 80 near the top. The top crossbeam 81 and the bottom crossbeam 82 are provided with a total of four linear motor movers, and at least one side of each mover is provided with at least one group of mover coils 90c. Preferably, mover coils 90c are arranged on three sides, which are relatively matched with the three sides inside the guide rail groove. Each side mover coil 90c can be arranged as an even number N groups along the longitudinal height, and the permanent magnets of the same length 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 this interval, including the longitudinal guide rail magnetic circuit, the transverse guide rail magnetic circuit and the bottom magnetic circuit in the guide rail rotating disk 90g. In particular, the permanent magnets on both sides of the guide rail rotating disk 90g are set to 1 group (different from the interval of the guide rail magnetic circuit, as the mark position of the magnetic circuit node), and this setting enables the crossbeam mover 90b to identify the position of the guide rail magnetic circuit.

[0080] A Hall sensor 100c is set on the top of the car 80, which 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 beam mover 90b is L. Specifically, after the Hall sensor 100c detects a flag signal of a magnetic circuit node: when running downward, it will run L distance; when running upward, it will run (the distance between the upper and lower beams of the car 80 - L), and at this time, the center of the beam mover 90b just coincides with the center of the guide rail rotating disk 90g. The conversion action of the running route of the car 80 can be implemented.

[0081] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0082] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
