Description

Technical Field

[0001] The present disclosure belongs to the technical field of elevators, and relates to a rotating rail assembly for an elevator system and a circulating elevator system thereof. Background Art

[0002] Traditional elevators are mainly rope-wheel traction shaft elevators. Each shaft has only one car, which runs between at least two vertical or inclined rigid guide rails with an inclination angle less than 15°. It consists of a double-tower and double-cage structure, and the two elevators operate independently of each other. This method has disadvantages such as low operating efficiency, long waiting time, and low shaft utilization rate due to the independent operation of elevators.

[0003] Chinese Patent Application No. 201310088693.X discloses a single-tower multi-cage elevator, including a single vertical guide rail frame with an upward guide rail on one side and a downward guide rail on the other side, and at least three construction elevator cages that can move along the upward and downward guide rails; the single vertical guide rail frame is spliced by standard sections and rotating rails. The elevator on the upward (downward) guide rail can rotate and transform through the rotating rail to move to the downward (upward) guide rail, realizing the circulating operation of the elevator on the upward and downward guide rails. Due to the complex structure of the rotating section and the time-consuming rotation transformation, it is not suitable for multiple settings on the guide rail to switch the running direction of the cage. Therefore, the application scenario of this method is limited. Summary of the Invention

[0024] Control the elevator car to move along the second hoistway to the second floor.

[0025] The beneficial effects of the present disclosure are:

[0035] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present disclosure. Apparently, the described embodiments are some, but not all, of the embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure. Therefore, the following detailed description of the embodiments of the present disclosure provided in the accompanying drawings is not intended to limit the scope of the present disclosure to be protected, but merely represents the selected embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.

[0036] Please refer to Figure 1 , an embodiment of the present disclosure provides a circulating elevator system for transporting passengers or goods between floors of a building.

[0037] The circulating elevator system includes:

[0038] At least one upshaft 1 and at least one downshaft 2.

[0039] The upshaft 1 and the downshaft 2 are the vertical shafts, that is, shaft structures arranged vertically, for the up and down movement of the elevator car 4 to one of the floors of the building.

[0040] Figure 1 Shown are two states of the circulating elevator system in the vertical shaft (the upshaft 1 or the downshaft 2). It should be noted that Figure 1 In [reference], the juxtaposition of the structures of the two vertical shafts is merely for illustration and comparison, and does not mean that the structures of the two vertical shafts exist in parallel.

[0041] The upshaft 1 and the downshaft 2 can be arranged on the outer side of the building wall, that is, the outer facade, or partially or fully accommodated in the wall space of the building, or accommodated in the internal space of the building.

[0042] Please refer to Figure 2 , in some embodiments, multiple upshafts 1 can be arranged on one wall of the building. Correspondingly, multiple downshafts 2 are arranged on the wall of the building opposite to this wall. The upshaft 1 and the downshaft 2 correspond one by one. The cross-shaft passage 3 is a straight passage.

[0043] Figure 2Among them, the range of the thickened square represents a floor plan, the white line outside the range of the thickened square represents the rotating track 7, and the white line within the range of the thickened square represents the elevator track in the cross-shaft passage 3. Among them, the part of the white line within the range of the thickened square that is connected to the white line outside the range of the thickened square represents the second fixed track 8, and the arrow represents the moving direction of the elevator car 4.

[0044] In some embodiments, at least one upshaft 1 and at least one downshaft 2 are arranged on one wall surface of the building. On the opposite wall surface, vertical shafts for opposite moving directions are respectively arranged correspondingly.

[0045] In some embodiments, the vertical shafts can be arranged on at least three wall surfaces of the building.

[0046] At this time, there may be at least one passage intersection position in the cross-shaft passage 3, where two mutually perpendicular passage segments intersect, and the track segments therein also intersect on the same horizontal plane. A track component that can rotate along the horizontal plane can be arranged at this passage intersection position, and through its 90° rotation, one of the two corresponding track segments is respectively made to be connected and closed, so that the elevator cars 4 with mutually perpendicular moving directions in the cross-shaft passage 3 can alternately pass through this intersection position.

[0047] Specifically, the structure and the action implementation mechanism of this track component can refer to the rotating track 7 described below.

[0048] This setting can improve the distribution of the vertical shafts on the building and the space utilization rate.

[0049] The circulating elevator system further includes:

[0050] At least two cross-shaft passages 3, each of the cross-shaft passages 3 is respectively arranged within one floor, each of the cross-shaft passages 3 is connected to at least one of the upshafts 1, and each of the cross-shaft passages is connected to at least one of the downshafts 2.

[0051] In some embodiments, cross-shaft passages 3 are respectively arranged on the top floor and the bottom floor (which can be located in the underground part of the building) of the building.

[0052] The top floor and the bottom floor can be dedicated to the switching of the up and down travel of the elevator car, or their floor spaces can also be used for other purposes, that is, they are floors for regular use.

[0053] The building further includes other floors except the above two floors, and these floors are also provided with cross-shaft passages 3, so that the elevator car 4 passes through them and switches between going up and down.

[0054] Furthermore, these floors are each floor of the building.

[0055] One of the said upward hoistways 1, one of the said cross-hoistway passages 3, one of the said downward hoistways 2 and another of the said cross-hoistway passages 3 form an annular passage.

[0056] Specifically, the upward hoistway 1 and the downward hoistway 2 in the annular passage are respectively the partial vertical hoistways between two cross-hoistway passages 3.

[0057] In the annular passage, track brackets are arranged both in the vertical hoistway and the cross-hoistway passage 3 along the running route of the elevator car 4, and the track brackets are fixed in the passage.

[0058] Figure 1 In the figure, to better show the structure of the circulating elevator system behind the track brackets, part of the track brackets close to the paper surface are hidden.

[0059] Specifically, the track brackets can be fixed on the walls or floors in the passage by expansion bolts. The expansion bolts have good anchoring performance and can withstand large tensile and shear forces to ensure the stability of the track brackets during the movement of the elevator car 4.

[0060] Elevator tracks are fixed on the track brackets.

[0061] Specifically, the elevator tracks can be connected to the track brackets by bolts. Bolt connection is convenient for disassembly and adjustment, and is convenient for fine-tuning the elevator tracks during installation and maintenance to ensure the straightness and accuracy of the elevator tracks.

[0062] The said upward hoistway 1 and the said downward hoistway 2 are respectively provided with multiple groups of first fixed rails 5, and each group of the first fixed rails 5 is arranged corresponding to one cross-hoistway passage 3, that is, within the height range of one floor.

[0063] The said upward hoistway 1 and the said downward hoistway 2 are respectively provided with multiple groups of guide rails 6, and each group of the guide rails 6 is arranged corresponding to one cross-hoistway passage 3.

[0064] The said guide rails 6 are arranged along the horizontal movement direction of the elevator car, and the said guide rails 6 are arranged between the rotating rails 7.

[0065] The said cross-hoistway passage 3 is provided with multiple groups of second fixed rails 8. Each group of the second fixed rails 8 of one cross-hoistway passage 3 is respectively arranged at the connection of this cross-hoistway passage 3 and each upward hoistway 1 and at the connection of this cross-hoistway passage 3 and each downward hoistway 2.

[0066] The first fixed rails 5, the guide rails 6 and the second fixed rails 8 are all part of the elevator tracks.

[0067] The first fixed rails 5, the guide rails 6 and the second fixed rails 8 are respectively straight tracks.

[0068] The circulating elevator system further includes:

[0069] A rotating rail assembly, which includes:

[0070] At least one set of rotating rails 7, and each set of the rotating rails 7 is correspondingly arranged at the first end, or both ends, of each set of the first fixed rails 5, and each set of the rotating rails 7 is correspondingly arranged at one end of each set of the second fixed rails 8.

[0071] The first end of the first fixed rail 5 is the top or bottom end of the first fixed rail 5.

[0072] The first end is correspondingly arranged with the moving mechanism 41. That is, if the moving mechanism 41 is arranged at the top of the elevator car 4, the first end is the top end of the first fixed rail 5. On the contrary, if the moving mechanism 41 is arranged at the bottom of the elevator car 4, the first end is the bottom end of the first fixed rail 5.

[0073] One end of the second fixed rail 8 is the end arranged at the connection of the second fixed rail 8 and a vertical shaft.

[0074] Rotating rails 7 are respectively arranged at both ends of the guide rail 6.

[0075] When the rotating rail 7 is in a vertical state, its two ends respectively cooperate with the adjacent first fixed rail 5 at this end. As shown in the right part of Figure 1 .

[0076] When the rotating rail 7 is in a horizontal state, the end close to the second fixed rail 8 thereof cooperates with the second fixed rail 8, and the end close to the guide rail 6 thereof cooperates with the guide rail 6.

[0077] A slight gap in the cooperation structure between the rotating rail 7 and one of the first fixed rail 5, the guide rail 6, and the second fixed rail 8 does not affect the movement of the moving mechanism 41.

[0078] The advantages of using the rotating rail 7 for route switching include:

[0079] Each set of rotating rails 7 can include multiple rotating rails 7. Each one is an independent component, and it is easier to replace when a failure occurs. At the same time, each set of rotating rails 7 only switches its state when the elevator car 4 passes through, which can reduce the number of operations and avoid wear.

[0080] 2. By the method of guiding switching through multiple rotating rails 7, guiding switching can be performed at multiple locations of the elevator car 4, making its overall movement more stable.

[0081] 3. The rotating radius of the rotating rail 7 is small, and the time for one state switching is short, which can improve the operation efficiency.

[0082] In some embodiments, the rotating track 7 is a straight track.

[0083] The rotating track 7 is arranged on the route of the elevator track. The state switching of the rotating track 7 can realize the closure of the elevator running route.

[0084] If all the rotating tracks 7 in a vertical passage are in the vertical state, the elevator route of this vertical passage is connected and closed, and the elevator car 4 can realize the complete moving stroke in this vertical passage.

[0085] When the elevator car 4 moves to a floor, the rotating track 7 can be switched from the vertical state to the horizontal state, so as to realize the guiding of the moving mechanism 41 of the elevator car 4 to be switched from vertical to horizontal, that is, the moving mechanism 41 moves from the first fixed track 5 to the rotating track 7, and then the rotating track 7 switches its state and changes the guiding, so that the moving mechanism 41 can move from it to the second fixed track 8.

[0086] Please refer to Figure 1 the left part of, specifically, the gear close to the second fixed track 8 directly moves to the second fixed track 8, and the gear far from the second fixed track 8 needs to move to the second fixed track 8 through the guiding track 6.

[0087] The circulating elevator system further includes:

[0088] A rotating mechanism, each group of rotating mechanisms is respectively used to drive each group of the rotating tracks 7 to switch between the vertical state and the horizontal state.

[0089] In some embodiments, the rotating mechanism includes a first servo motor and a transmission connecting rod. One end of the transmission connecting rod is fixed to the rotating shaft of the rotating track 7, and the other end is connected to the output shaft of the first servo motor. The rotating track 7 is driven to rotate around the rotating shaft by the first servo motor.

[0090] At least one elevator car 4, the elevator car 4 is provided with a moving mechanism 41, and the moving mechanism 41 is used to cooperate with any one of the first fixed track 5, the guiding track 6, the second fixed track 8, and the rotating track 7 and move on it.

[0091] In some embodiments, the circulating elevator system further includes:

[0092] A locking mechanism, each group of the locking mechanisms is respectively used to lock a group of the rotating mechanisms, so that the rotating track 7 is locked in the vertical state or the horizontal state.

[0093] That is, the locking mechanism is linked with the rotating mechanism, and is used to lock the rotating mechanism after the rotating rail 7 switches to the target state, so as to prevent the rotating mechanism from driving the rotating rail 7 to rotate accidentally during the movement of the elevator car 4 on the rotating rail 7, ensuring the safety and stability of the elevator system.

[0094] In some embodiments, the state of the rotating rail 7 can be detected in real time by an angle sensor. For example, the rotation angle of the rotating shaft is detected, and each rotation is 90°.

[0095] In some embodiments, the locking mechanism can be an electromagnetic brake installed inside the first servo motor. For example, when the electromagnetic brake is powered on, the motor shaft can rotate freely. When the rotating rail 7 switches to the target state, the stator coil loses power, and only the permanent magnet remains in the stator to form a single magnetic circuit, attracting the armature on the rotor, thereby realizing the locking of the motor shaft and achieving a stable transition between the rotating rail 7 and the fixed rail.

[0096] Installing the locking mechanism inside the rotating mechanism has the advantages of stable mechanical structure, not being easily interfered by the external environment, and long service life.

[0097] Please refer to Figure 1 , in some embodiments, the moving mechanism 41 is arranged on the top of the elevator car 4, and there are four moving mechanisms 41.

[0098] Each moving mechanism 41 extends along the direction of its rotating shaft to the outside of the elevator car 4, and a gear is arranged on the extended part.

[0099] The first fixed rail 5, the guide rail 6, the second fixed rail 8, and the rotating rail 7 respectively include rack tracks, and the gears mesh with the rack tracks.

[0100] When the gear rotates, it can drive the elevator car 4 to move along the rack track.

[0101] Corresponding to each moving mechanism 41, there is a rotating rail 7.

[0102] Furthermore, all elevator tracks include rack tracks for the movement of the gears. The interfaces of each section of the track are calibrated by laser alignment to avoid meshing impact.

[0103] A T-shaped guide rail can be arranged parallel to the rack track and cooperate with the guide wheels on the side of the elevator car 4 to limit the lateral displacement of the elevator car 4 on the track.

[0104] In some embodiments, when the rotating rail 7 is in the vertical state, the direction of the rotating rail 7 is perpendicular to the horizontal plane, and the rotating rail 7 is located outside the gear.

[0105] At this time, the elevator car 4 correspondingly stops at a predetermined position on a floor provided with the cross-shaft passage 3.

[0106] The predetermined position is the position in the vertical shaft connected to the cross-shaft passage 3, and the gear of the elevator car 4 is located at the position corresponding to the guide rail 6.

[0107] On both sides of the gear are respectively provided a set of rotating rails 7 in a vertical state.

[0108] Further, when the elevator car 4 moves vertically and passes through other elevator rails in the vertical shaft, the corresponding elevator rails are located outside the gear.

[0109] At this time, avoidance openings are formed on both sides of the guide rail 6 to allow the gear of the elevator car 4 to pass through when the elevator car 4 moves vertically.

[0110] Similarly, it corresponds to the elevator car 4 stopping at a predetermined position on a floor provided with the cross-shaft passage 3. When the rotating rail 7 is in a horizontal state, the direction of the rotating rail 7 is parallel to the horizontal plane, and the rotating rail 7 is located below the gear.

[0111] Further, when the elevator car 4 moves horizontally and passes through the guide rail 6 and the second fixed rail 8 respectively, the corresponding elevator rails are located below the gear.

[0112] That is, the rotation angle of the rotating rail 7 each time it switches states is 90°, and the rotation directions are opposite.

[0113] When the elevator car 4 reaches the predetermined position on each floor provided with the cross-shaft passage 3 from the vertical shaft, its moving mechanism 41 moves to the first part of the rotating rail 7. Please refer to the right part of Figure 1 , the first part is the upper half of the rotating rail 7, the second part is the lower half of the rotating rail 7, and the rotation axis of the rotating rail 7 is arranged between the two parts.

[0114] In some embodiments, the elevator car 4 is provided with a motor for driving the moving mechanism 41 to make the elevator car 4 move cyclically along the elevator rails in the annular passage.

[0115] The motor is a second servo motor, and the precise adjustment of the rotation speed can be achieved through vector control.

[0116] The second servo motor transmits the torque to the rack rail through a planetary gear set, pushes the gear to rotate, and meshes with the rack rail in real time, thereby driving the elevator car 4 to move.

[0117] The moving mechanism 41 may further include a laser alignment sensor for detecting the meshing offset of the gear on the rack rail in real time and fine-tuning the gear phase angle through the second servo motor.

[0118] When the elevator car 4 reaches the predetermined position on each floor from the vertical shaft, it can stay through the locking mechanism.

[0119] For example, the locking mechanism is a ratchet-pawl system.

[0120] Specifically, a one-way ratchet is integrated at the end of the gear shaft, and a pawl is correspondingly installed on the wall of the vertical shaft. When the elevator car 4 moves, the electromagnet is energized to attract the pawl. When the elevator car 4 stays, the electromagnet is de-energized, and the pawl is pushed by a spring to embed into the ratchet tooth groove, locking the ratchet and preventing the gear shaft from rotating in the reverse direction, so that the elevator car 4 will not fall.

[0121] In some embodiments, the cross-shaft passage 3 includes at least one docking port, and the docking port is far from the up shaft 1 and the down shaft 2.

[0122] Conventional elevators are provided with elevator openings at the positions of the vertical shafts on each floor for the elevator car 4 to stay, and enable passengers or goods to get on and off here. However, for floors with a relatively large planar area, some positions are far from the vertical shaft, resulting in inconvenience for passengers or goods to get on and off and low transportation efficiency.

[0123] Based on the circulating elevator operation system provided by the embodiments of the present disclosure, since the cross-shaft passage 3 passes through the interior of the floor, multiple docking ports can be set at multiple positions inside the floor, and the cross-shaft passage 3 passes through, so that the accessibility of the elevator car 4 can be achieved.

[0124] If the cross-shaft passage 3 is open, the elevator car 4 can be controlled to stay along the cross-shaft passage 3 at any time.

[0125] If the cross-shaft passage 3 is closed, correspondingly, an elevator opening is provided inside the floor to connect the elevator car 4.

[0126] In some embodiments, the circulating elevator system is a multi-tower multi-car circulating elevator system, including multiple vertical shafts and multiple elevator cars 4. Multiple elevator cars 4 operate simultaneously.

[0127] In some embodiments, the circulating elevator system further includes:

[0128] A control module for controlling the moving routes of one or more elevator cars 4 to avoid route conflicts between multiple elevator cars 4.

[0129] Furthermore, the position of the elevator car 4 can be obtained by multiple position sensors arranged in the passage.

[0130] In some embodiments, the circulating elevator system further includes:

[0131] An emergency braking module is used to control one or more elevator cars 4 to stop moving when the control module malfunctions, avoiding collisions with each other, so as to enhance the safety when multiple elevator cars 4 operate simultaneously.

[0132] Please refer to Figure 3 In addition, an embodiment of the present disclosure also provides a control method for the above-mentioned circulating operation elevator system, including:

[0133] S1, controlling the first elevator car to move along a first vertical shaft to the first floor. At this time, the first rotating rail is in the vertical state, where the first rotating rail is the rotating rail corresponding to the first vertical shaft on the first floor, and the first floor is the floor provided with the first cross-shaft passage.

[0134] The first vertical shaft is an upshaft or a downshaft.

[0135] The movement to the first floor means moving to a predetermined position at the connection of the first vertical shaft and the first cross-shaft passage and staying there.

[0136] At this time, the moving mechanism moves through the first fixed rail corresponding to the first floor to the vertically positioned first rotating rail.

[0137] Moreover, the elevator car is kept stationary in the first vertical shaft by the locking mechanism.

[0138] S2, controlling the first rotating rail to switch to the horizontal state.

[0139] At this time, the locking mechanism releases the elevator car, so that the moving mechanism moves onto the first cross-shaft passage through its cooperation structure with the second fixed rail.

[0140] S3, controlling the first elevator car to move along the first cross-shaft passage to the connection with the second vertical shaft. At this time, the second rotating rail is in the horizontal state, where the second rotating rail is the rotating rail corresponding to the second vertical shaft on the first floor.

[0141] The second vertical shaft is an upshaft or a downshaft other than the first vertical shaft.

[0142] At this time, the moving mechanism moves through the second fixed rail corresponding to the first cross-shaft passage and the second vertical shaft to the horizontally positioned second rotating rail.

[0143] S4. Control the second rotating rail to switch to the vertical state, so that the moving mechanism moves to the second vertical shaft through its mating structure with the second fixed rail in step S3 and its mating structure with the guide rail corresponding to the second fixed rail in step S3.

[0144] S5. Control the elevator car to move along the second shaft and move to the second floor.

[0145] The second floor is the floor with a cross-shaft passage other than the first floor.

[0146] After that, continue to execute the above steps S1 - S5, so that the elevator car can move cyclically in the circular passage, stop at a certain position therein, and switch to move in other circular passages.

[0147] In some embodiments, the method further includes:

[0148] After the moving mechanism leaves the first rotating rail, at a moment with a preset time interval backward, control the first rotating rail to switch back from the horizontal state to the vertical state to wait for the next elevator car to move onto it for staying at this floor or continuing to move vertically.

[0149] Correspondingly, before the same elevator car reaches another second fixed rail on this floor, at a moment with a preset time interval forward, control the corresponding second rotating rail to switch from the vertical state to the horizontal state, so that the moving mechanism can move to the second rotating rail through the mating structure to improve the operation efficiency.

[0150] In some embodiments, after the elevator car completes one operation, it can return to the standby position in the building and wait for the next movement control.

[0151] In some embodiments, each floor and each elevator entrance on each floor are numbered in sequence as F i,j , where i represents the floor number and j represents the elevator entrance number, and each elevator car is identified by an identification code to facilitate the control of the movement route.

[0152] For example, controlling elevator car A to elevator entrance F 9,3 means controlling elevator car A to move to the third elevator entrance on the 9th floor.

[0153] The operation flow chart of elevator car A can be referred to Figure 4 .

[0154] The circulating elevator system provided by the present disclosure realizes the circulating operation of the elevator system within the building floors through the rotating track and the cross-shaft passage, improves the transportation efficiency and the utilization rate of the elevator car, thereby improving the economic benefits, and is applicable to various scenarios of high-rise and super high-rise buildings, effectively solving the problems of passenger and personnel transportation in buildings.

[0155] The above are only the preferred embodiments of the present disclosure and are not intended to limit the present disclosure. For those skilled in the art, the present disclosure may have various changes and modifications.
