In the building design planning stage, the number of floors of a building, the maximum energy carrying capacity and the running speed of an elevator and the future traffic of the building determine the demand degree of the building for the elevator. If the building has a high number of floors and a large amount of people such as an office building or a shopping mall, the larger the demand degree for the elevator is, the more planning space for the elevator in the building is, and the more land resources and economic cost are occupied. In the high-rise building that the flow of people is big, traditional traction type elevator can only move the mode of a car in same elevartor shaft, receives the restriction of the biggest carrying capacity of elevator and functioning speed, and the availability factor of elevator has more and more can not satisfy the high-rise building that the flow of people is big to the demand of elevator, can only satisfy the demand through the quantity that increases the elevator.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, in this embodiment, the elevator operating system according to the present invention includes 4 elevator shafts, and the 4 elevator shafts are arranged in a circumferential array, i.e., elevator shaft i serves as a rising passage, elevator shaft iii serves as a descending passage, and elevator shaft ii and elevator shaft iv serve as a stopping passage. Of course, it is also possible to use elevator shaft i as the descent passage, elevator shaft iii as the ascent passage, and elevator shafts ii and iv as the pause passage. Or the elevator shaft I and the elevator shaft III are only used as pause channels, the elevator shaft II is used as an ascending channel, and the elevator shaft IV is used as a descending channel; or the elevator shaft I and the elevator shaft III are used as a pause passage, the elevator shaft II is used as a descending passage, and the elevator shaft IV is used as an ascending passage. The invention is only exemplary of the case where hoistway i is a hoistway, hoistway ii is a parking hoistway, hoistway iii is a hoistway, and hoistway iv is a parking hoistway. In addition, the 4 elevator shafts disclosed in the present invention are merely exemplary, and the number of elevator shafts includes at least 3, including 3, such as 5 or 6.

In the cylindrical space formed by 4 elevator shafts disclosed in the invention, a pair of horizontal annular guide rail parts as shown in fig. 1 is installed on the wall at the bottom of the position where each layer of the cage needs to be stopped. The horizontal ring-shaped guide rail part comprises an inner ring-shaped guide rail 10 and an outer ring-shaped guide rail 20 which are concentric. Referring to fig. 2, the inner circular guide rail 10 is composed of a plurality of inner circular horizontal rail sections 11, and the outer circular guide rail 20 is composed of as many outer circular horizontal rail sections 21 as the inner circular horizontal rail sections 11. As seen from fig. 2, the lengths of the inner circular ring horizontal track sections 11 are different, and the lengths of the outer circular ring horizontal track sections 21 are different. The number of inner circular horizontal track segments 11 is the same as the number of outer circular horizontal track segments 21. A first cross track assembly 30 which can realize mutual switching between the vertical direction and the horizontal direction through rotation is arranged between every two adjacent inner circular ring horizontal track sections 11. Similarly, a second intersection track assembly 36 is disposed between each two adjacent outer circular horizontal track segments 21. It will be appreciated that the number of first cross track assemblies 30 provided on the inner circular track 10 is the same as the number of second cross track assemblies 36 provided on the outer circular track 20.

Referring to fig. 2 and 4, two first crossing track assemblies 30 opposite to each other on each two adjacent layers of the inner circular guide tracks 10 are provided with vertical toothed guide tracks 40. Referring to fig. 4, the opposite second intersection track assembly 36 of each two adjacent upper and lower layers of the outer circular track 20 is also provided with a vertical toothed track 40. Here, the opposite means the same vertical line direction of the inner circular guide rails 10 of the adjacent two layers and the same vertical line direction of the outer circular guide rails 20 of the adjacent two layers.

Referring to fig. 2, a vertical movement power mechanism 60 that ascends or descends along 4 vertical toothed guide rails 40 is provided on each of both side edges 51 of the car 50, and a lateral movement power mechanism 70 that moves the car 50 to the left and right in the horizontal direction is provided on the bottom of the car 50. Specifically, referring to fig. 2 and 8, as one example, the vertical motion power mechanism 60 includes four first motors 61 and four gears 62 respectively disposed on the left and right sides 51 of the car 50, eight first motors 61 and eight gears 62 are disposed near eight corners of the two sides of the car 50, and the eight first motors 61 respectively control the eight gears 62 to move up and down on the four vertical toothed guide rails 40 of the same elevator shaft. It should be noted that the eight gears 62 synchronously move up and down on the four vertical toothed guide rails 40 to drive the car 50 to synchronously move up and down on the four vertical toothed guide rails 40 of the same elevator shaft.

Referring to fig. 5 and 11, the elevator operating system further includes two second motors 63 respectively provided at lower ends of both side edges 51 of the car 50 and two lead screws 64 connected to the second motors. That is, a second motor 63 is connected to a lead screw 64. As a preferred embodiment, the traverse power mechanism 70 in fig. 2 includes a bottom plate 71 disposed at the bottom of the car 50, and four translation modules 72 disposed at four corners of the lower end surface of the bottom plate 71, wherein each translation module 72 is provided with a roller 727; the four second motors 63 control the traverse power mechanism 70 to move in the vertical direction through the four lead screws 64.

Referring to fig. 10, fig. 10 is a detailed view of the translation module 72. Each translation module 72 includes a third motor 722, a drive pulley 723, a timing belt 724, a driven pulley, a slider 725 disposed on the mounting plate 721, a fourth motor 726 disposed on the slider 725, and the aforementioned rollers 727. The output end of the third motor 722 is connected with the driving wheel 723, one end of the synchronous belt 724 is connected with the driving wheel 723, the other end of the synchronous belt 724 is connected with the driven wheel (shielded by the sliding block 725), the sliding block 725 is fixed on the driven wheel through a belt fixing piece and a belt, and the roller 727 is arranged at the output end of the fourth motor 726. It will be appreciated that the four translation modules 72 are distributed at the four corners of the base plate 71, with the inner two of the four rollers 727 being distributed on the inner circular guide track 10 and the outer two being distributed on the outer circular guide track 20. Referring to fig. 2 and 10, the third motor 722 drives the roller 727 to perform a telescopic motion in a direction perpendicular to the car door 52, i.e., a telescopic motion inward and outward, and the fourth motor 726 drives the roller 727 to rotate so that the roller 727 translates on the inner circular guide rail 10 and the outer circular guide rail 20.

Referring to fig. 2 and 9, the aforementioned first cross rail assembly 30 includes a fifth motor 31 and a first cross rail 32. Convex arc structures 33 are processed at two ends of the long side of the track 32 at the first intersection, a plurality of straight teeth 34 are processed at one side of two side edges, and the fifth motor 31 is installed at the other side of the two side edges and is opposite to the straight teeth 34; the shape of the upper end surface 35 of the first cross track 32 is the same as the shape of the upper end surface 12 of the inner circular horizontal track section 11, and the purpose of the shape is to allow the roller 727 to roll smoothly on the inner circular horizontal track section 11.

Referring to fig. 2 and 12, the aforementioned second cross rail assembly 36 includes a fifth motor 31 and a second cross rail 37. The second intersection track 37 differs from the first intersection track 32 in that the radii of the upper end face structures are different and the remaining structures are the same. In addition, the position where the fifth motor 31 is placed on the second intersection rail 37 is the same as the position where the fifth motor 31 is placed on the first intersection rail 32. The second cross track assembly 36 is adapted to be mounted between two adjacent outer circular guide rails 20.

Referring to fig. 3 and 4, the vertical toothed rail 40 is formed with straight teeth 41 to facilitate the meshing movement of the gear 62 of fig. 8 on the straight teeth 41.

Referring to fig. 4, when the fifth motor 31 controls the first cross track 32 to rotate to the vertical direction, the upper and lower ends of the first cross track 32 are respectively in continuous engagement with the two vertical toothed guide rails 40 at the upper and lower ends between the two inner circular horizontal track sections 11. When the fifth motor 31 controls the second intersection track 37 to rotate to the vertical direction, the upper and lower ends of the second intersection track 37 are respectively in uninterrupted engagement with the two vertical toothed guide rails 40 located at the upper and lower ends between the two outer circular ring horizontal track sections 21. The 8 gears 62 in fig. 4 can move up and down along the inner and outer 4 vertical toothed guide rails 40, so that the car 50 can run smoothly in the vertical direction.

Referring to fig. 2, 5 and 9, when the fifth motor 31 controls the first cross track 32 to rotate to the horizontal direction, the left and right ends of the first cross track 32 respectively form an uninterrupted connection with the two inner circular horizontal track sections 11. The sections of the first cross rails 32 are continuously connected with the sections of the inner circular ring horizontal rail sections 11 to form the inner circular ring guide rail 10 shown in fig. 2. Similarly, referring to fig. 2, 5 and 12, when the fifth motor 31 controls the second intersection track 37 to rotate to the horizontal direction, the plurality of second intersection tracks 37 and the plurality of outer circular ring horizontal track segments 21 form an uninterrupted connection to form the outer circular ring guide 20.

Referring to fig. 6, car doors 52 of the elevator operating system are provided at an ascending passageway i and a descending passageway iii as shown in fig. 1, respectively; alternatively, two sets of car doors 52 are provided at the pause passage ii and the pause passage iv, respectively. If the car doors 52 are provided in the ascending and descending paths i and iii, respectively, there are advantages in that: passengers can directly enter and exit after the elevator arrives at the appointed floor, and the passengers can enter and exit without waiting for the elevator car to move to the intermediate pause passage. The disadvantages are that: when a certain cage located in the ascending channel I or the descending channel III arrives at a certain floor, if the time occupied by passengers entering and exiting the cage at the certain floor is too long, the operation of other cages in the channel is influenced.

If two sets of car doors 52 are provided at the pause lane ii and the pause lane iv, respectively, the advantages are: when the lift car in the ascending channel I ascends to a designated floor, the lift car transversely moves to the pause channel II to enable passengers to enter and exit, and therefore other running lift cars in the ascending channel I cannot be influenced. Similarly, when the elevator car in the descending passage III descends to a designated floor, the elevator car moves to the pause passage IV for passengers to enter and exit, so that other running elevator cars in the descending passage III are not influenced. The disadvantages are that: when the elevator car arrives at a designated floor, the elevator car needs to move transversely to a second pause passage II and a pause passage IV, and passengers can not experience good experience when taking the elevator.

Referring to fig. 9 and 12, the two ends of each inner circular horizontal track segment 11 are provided with concave circular arc-shaped structures 13 which are respectively and uninterruptedly connected with the convex circular arc structures 33. Referring to fig. 4, both ends of each outer circular ring horizontal track section 21 are also provided with concave circular arc structures 13, and the upper and lower ends of the vertical toothed guide rail 40 are also provided with concave circular arc structures 13, respectively. The benefits of this are: 1. in the horizontal direction, the first cross track 32 can form uninterrupted connection with the inner circular ring horizontal track section 11, and the second cross track 37 can also form uninterrupted connection with the outer circular ring horizontal track section 21; 2. in the vertical direction, the first intersection track 32 and the vertical toothed rail 40 form an uninterrupted engagement, and the second intersection track 37 and the vertical toothed rail 40 form an uninterrupted engagement. The stable operation of the cage 50 in both the vertical direction and the horizontal direction is ensured.

Referring to fig. 1, every two adjacent elevator shafts are circumferentially spaced by a distance K. This prevents two adjacent elevator shafts from colliding when traversing in the horizontal direction.

In the system, a first time t1 required for the car to travel two adjacent floors in the ascending path or two adjacent floors in the descending path is longer than a second time t2 required for the car to traverse from one hoistway to another adjacent hoistway. Assuming that the first time required for the car to ascend from the 1 st floor to the 2 nd floor in the pseudo-ascent path i is t1 and the second time required for the car to traverse from the ascent path i to the pause path ii in the horizontal direction is t2, the ascent path in the vertical direction can allow a plurality of cars to travel simultaneously as long as t1> t2 is programmed and the precondition that the distance between adjacent cars must be greater than the distance of 1 floor is satisfied. For example, if the car 1 at the 1 st floor of the hoistway needs to be raised to the 10 th floor and the car 2 at the 3 rd floor needs to be raised to the 7 th floor, the car 1 at the 1 st floor and the car 2 at the 3 rd floor can run simultaneously: when the No. 2 cage of the 3 rd floor rises to the 7 th floor, the No. 1 cage of the 1 st floor originally rises to the 5 th floor, and when the No. 1 cage continues to rise from the 5 th floor to the 6 th floor, the No. 2 cage stopped at the 7 th floor already moves to the 2 nd elevator shaft pause passage and does not collide with the No. 1 cage continuing to rise from the 6 th floor. Similarly, the 4 th hoistway of the 4 th cage can allow a plurality of cages to run simultaneously by the descending path in the vertical direction on the premise that the distance between the adjacent cages must be greater than the distance of 1 floor.

In the elevator system described below, the cars on the same floor can be moved arbitrarily to any hoistway: namely, a car in the elevator shaft I can move to an elevator shaft II serving as a pause passage and can also move to an elevator shaft IV serving as a pause passage; the car of the elevator shaft ii as the pause passage may be moved to the elevator shaft i as the ascending passage or to the elevator shaft iii as the descending passage.

The realization of car sideslip motion:

when the car needs to be changed from vertical movement to horizontal movement, the 4 fifth motors 31 in fig. 5 respectively control the two first cross tracks 32 and the two second cross tracks 37 to rotate to the horizontal state, the first cross tracks 32 are connected with the inner circular ring horizontal track section 11 to form an uninterrupted inner circular ring guide rail (see fig. 2), and the second cross tracks 37 are connected with the outer circular ring horizontal track section 21 to form an uninterrupted outer circular ring guide rail. Referring to fig. 5 and 10, the third motor 722 at the bottom of the car 50 drives the rollers 727 to extend outward to the right above the inner circular horizontal track segment 11 and the outer circular horizontal track segment 21 in a direction perpendicular to the car door 52, referring to fig. 11, then the second motor 63 at the bottom of the car drives the lead screw 64 (see fig. 11) to rotate, the lead screw 64 performs a spiral motion with the lead screw nut (shielded by the bottom plate) fixed on the bottom plate 71 in fig. 2, and further drives the 4 rollers 727 at the bottom of the car to perform a descending motion in the vertical direction until the 4 rollers 727 contact the inner circular horizontal track segment 11 and the outer circular horizontal track segment 21. Finally, the fourth motor 726 in fig. 10 drives 4 rollers 727 to rotate, so that the car 50 moves transversely in the inner circular horizontal track section 11 and the outer circular horizontal track section 21.

Referring to fig. 2, 5 and 7, the vertical toothed guide rail between every two adjacent inner circular ring horizontal track sections and the vertical toothed guide rail between every two adjacent outer circular ring horizontal track sections are oppositely arranged. The relative arrangement here means that the straight teeth on the vertical toothed guide rail between every two adjacent inner circular ring horizontal track sections face outwards, and the straight teeth on the vertical toothed guide rail between every two adjacent outer circular ring horizontal track sections face inwards. Only then can 4 gears on the car move up and down on four vertical toothed guide rails.

The realization of car elevating movement:

referring to fig. 4, when the car 50 needs to move up/down, 4 fifth motors 31 control 4 first cross rails 32 to rotate to a vertical direction to engage with vertical toothed guide rails 40 fixed on the elevator shaft wall to form an uninterrupted vertical rail, the car 50 moves to a position where gears 61 on the car and vertical rack rails 40 are engaged (see fig. 8), then the second motor 63 at the bottom of the car drives a lead screw 64 (see fig. 11) to rotate, the lead screw 64 performs a spiral motion with a lead screw nut (shielded by a bottom plate) fixed on a bottom plate 71 in fig. 2, and then drives 4 rollers 727 (see fig. 11) to retract upwards in the vertical direction, after the 4 rollers 727 disengage from contact with an inner circular ring horizontal rail section 11 and an outer circular ring horizontal rail section 21, the third motor 722 in fig. 10 drives the 4 rollers 727 to retract towards the center of the car 50, so that the four translation modules 72 (see fig. 10) in fig. 5 do not contact with inner circular ring horizontal rail sections 11 and outer circular ring horizontal rail sections 21 when the car 50 moves up/down vertically, and up/down The circular ring horizontal track section 11 and the external circular ring horizontal track section 21 interfere.

Therefore, the technical scheme disclosed by the invention can realize the following technical effects:

the same elevator shaft allows a plurality of cages to run simultaneously, and the mutual running is not influenced by the running of other cages: that is, the 1 st elevator shaft is used as a lifting passage to allow a plurality of elevator cars to simultaneously ascend to different floors, and the mutual operation is not influenced by other cars; the 3 rd elevator shaft is used as a descending passage to allow a plurality of elevator cars to descend to different floors at the same time, and the mutual operation is not influenced by other cars;

2. the cars on the same floor can be moved to any elevator shaft at will: namely, the cage of the 1 st elevator shaft can move to the 2 nd elevator shaft pause passage and can also move to the 4 th elevator shaft pause passage; the car of the 2 nd suspension passage can be moved to the 1 st elevator shaft ascending passage and also can be moved to the 3 rd elevator shaft descending passage.

It should be noted that when 3 elevator shafts are adopted, the collision accident caused by the fact that the bridge box is stopped in the elevator shaft stopping passage is avoided through the sensor and software control.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
