Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of elevators, and in particular to a door system of a multi-car intelligent parallel elevator. BACKGROUND

[0002] In modern social and economic activities, elevators have become an indispensable vertical transportation tool for carrying people or goods. Since the invention of elevators in 1854, elevator cars have been running in the way of steel wire rope wheel traction drive, through the setting of machine room, traction motor and speed reducer on the top floor of the building to drive the steel wire rope to pull the car and counterweight to run on the track in the shaft. This driving mode makes it usually only run one car in a single shaft, and the single-car running mode of the elevator can still meet the use demand in low-rise buildings and floors with small passenger flow. With the rapid development of modern cities, high-rise buildings and super high-rise buildings with large population density are rising, and the shortcomings of long waiting time and low transportation efficiency of the single-car running mode of the elevator are being magnified. This traditional single-car elevator running mode has been difficult to meet the needs of the rapid development of modern urban buildings.

[0003] To improve the utilization rate of building space and the transportation efficiency of elevators and reduce the cost of buildings and elevators, with the continuous development of engineering technology, a multi-car parallel elevator is being developed and applied. The multi-car parallel elevator adopts a direct drive technology without traction steel wire rope, realizes the simultaneous running of multiple elevator cars in the same shaft, and the elevators between shafts can switch shafts to run and realize overtaking.

[0004] However, if the elevator system of the existing building is improved to apply the multi-car parallel elevator, some problems will be encountered. The existing building elevator shaft is designed and built based on the traditional elevator system with a shaft-to-car ratio of 1:1 (one shaft for one car), in order to meet the construction and installation of the guide rails on both sides of the elevator car, a considerable proportion of the shafts adopt a structure mode of single-shaft closed pouring or adjacent shaft ring beam interval connection, which is not conducive to the realization of the switching function of the car in the adjacent shaft of the intelligent elevator system.

[0036] The specific embodiments of the present application will be described below in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely intended to illustrate and explain the present application, and are not intended to limit the present application.

[0037] For the convenience of description, spatial relative terms such as "above", "upper", "top surface", "upper surface", etc. can be used herein to describe the spatial positional relationship of one device or feature with respect to other devices or features as shown in the drawings. It should be understood that the spatial relative terms are intended to include different orientations in use or operation in addition to the orientation of the devices as described in the drawings. For example, if the devices in the drawings are inverted, the device described as "above" or "on" other devices or structures will be positioned "below" or "under" the other devices or structures. Thus, the exemplary term "above" can include both "above" and "below" orientations. The devices can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein are interpreted accordingly.

[0038] The door system of a multi-car intelligent parallel elevator, the elevator comprising a plurality of cars 1, at least two parallel arranged main rails and at least one cut rail device, both ends of the cut rail device being connected to two main rails respectively, the car 1 switching between different main rails through the cut rail device. The car 1 is operated by a self-driving system without a traction steel wire rope.

[0039] Two parallel main rails are arranged in a shaft, and at least two hall doors between a floor and the shaft include two, as shown in Figures 1-4 , hall door one 4 and hall door two 5, hall door one 4 and hall door two 5 have the same structure, hall door one 4 and hall door two 5 correspond to the car 1 on the two main rails respectively, and hall door one 4 and hall door two 5 cooperate with the car door 2 of the car 1 on the two main rails respectively.

[0040] The hall door one 4 and the hall door two 5 are arranged in parallel staggered mode, and the hall door one 4 and the hall door two 5 are movable in the direction parallel to the plane where the hall door one 4 and the hall door two 5 are arranged.

[0041] In the embodiment, the moving direction of the hall door one 4 and the hall door two 5 is parallel to the horizontal plane, and when the hall door one 4 or the hall door two 5 is opened, the hall door one 4 and the hall door two 5 are at least partially stacked or overlapped, and the hall door one 4 and the hall door two 5 are not opened at the same time. Preferably, the opening position of the hall door one 4 substantially overlaps with the closing position of the hall door two 5, and the opening position of the hall door two 5 substantially overlaps with the closing position of the hall door one 4. The arrangement that the hall door one 4 and the hall door two 5 are not opened at the same time improves the safety, and prevents the interval between the two cars 1 from being exposed when the hall doors are opened at the same time. If a separation component is arranged at the interval between the two cars 1, the complexity of the hall door is increased.

[0042] Specifically, as shown in Figure 2 and 3 , the arrows in the figure are the moving directions of the corresponding hall doors. When the hall door one 4 is opened, the hall door one 4 moves towards the hall door two 5 and is moved to be at least partially stacked with the hall door two 5, at this time, the hall door one 4 is opened, and the hall door two 5 remains closed. When the hall door two 5 is opened, the hall door two 5 moves towards the hall door one 4 and is moved to be at least partially stacked with the hall door one 4, at this time, the hall door two 5 is opened, and the hall door one 4 remains closed.

[0043] The door structure including the hall door one 4 and the hall door two 5 is a bidirectional side-opening door structure, and the specific structure of the door is shown in Figure 4 , the door includes the hall door one 4, the hall door two 5, a door frame 6, at least two hall door lock assemblies 7, and at least two sets of guide limiting assemblies 8.

[0044] The guide limiting assembly 8 is arranged on the door frame 6. In the embodiment, two sets of guide limiting assemblies 8 are arranged, and the two sets of guide limiting assemblies 8 are arranged in parallel. The hall door one 4 and the hall door two 5 are arranged on the two sets of guide limiting assemblies 8 respectively, thereby forming the parallel staggered arrangement of the hall door one 4 and the hall door two 5. The hall door one 4 and the hall door two 5 are movably arranged along the two sets of guide limiting assemblies 8 respectively.

[0045] The side of the hall door one 4 and the hall door two 5 close to the car 1 is respectively provided with a hall door lock assembly 7, and the hall door one 4 and the hall door two 5 are locked on the door frame 6 through the hall door lock assembly 7. The hall door lock assembly 7 can adopt the structure and product in the prior art. When the hall door one 4 and the hall door two 5 are locked respectively, the hall door one 4 and the hall door two 5 completely separate the shaft and the floor.

[0046] The hall door one 4 and the hall door two 5 are cooperated with the car door 2 of the car 1 on the two main rails to start, and the start includes opening and closing. The cooperation mode of the hall door one 4 or the hall door two 5 and the car door 2 can adopt the cooperation mode of the hall door and the car door in the prior art.

[0047] The well width is L, then

[0048] L = 2 x L1 + 2 x L3 + L4

[0049] Wherein, L1 is the width of the car 1, L4 is the interval between the two cars 1, L3 is the distance between the car 1 and the well side wall.

[0050] The car door 2 of the car 1 which is linked with the hall door one 4 and the hall door two 5 can adopt various forms, which are described in detail below.

[0051] Embodiment one

[0052] The car door 2 is a middle split type. The car door 2 includes two symmetrically arranged first car doors 9, which are retractable and movable: when the car door 2 is closed, the two first car doors 9 fit together to cover the entrance and exit of the car 1; when the car door 2 is opened, the two first car doors 9 exit the entrance and exit of the car 1, so that the entrance and exit of the car 1 is partially or completely exposed.

[0053] The first car door 9 includes a plurality of door leaves, which are arranged in parallel and staggered in sequence, each door leaf is linearly movable in the plane where it is located, and the moving directions of the plurality of door leaves are parallel to each other.

[0054] When the car door 2 is closed, the plurality of door leaves of each first car door 9 are sequentially connected, the first car door 9 formed by the plurality of door leaves is connected to the side wall of the car 1 at one end and to one door leaf of the other first car door 9 at the other end, forming a cover for the entrance and exit of the car 1. Preferably, the plurality of door leaves of each first car door 9 do not overlap when the car door 2 is closed.

[0055] When the car door 2 is opened, the plurality of door leaves of each first car door 9 move to the outside of the car 1, or to the side of the car 1 away from the inside of the car 1, so that the plurality of door leaves of each first car door 9 are sequentially stacked or at least partially overlapped, so that the exit of the car 1 is completely exposed.

[0056] The movement of the plurality of door leaves of the first car door 9 can change the width of the first car door 9, i.e. the first car door 9 has a telescopic function.

[0057] Based on the above structure, the relationship between the dimensions is as follows:

[0058] L1 = N x L5

[0059] L5 < L3

[0060] L5 < L4

[0061]

[0062] Wherein, N is the number of door leaves of the car door 2 of each car 1, N ≥ 4; L5 is the width of each door leaf.

[0063] It should be noted that the two car doors 2 are respectively linked with the two hall doors, and the two hall doors cannot be opened at the same time, that is, the two car doors 2 cannot be opened at the same time, and the interval L4 between the two cars 1 has at most one door leaf, and thus the interval L4 between the two cars 1 is greater than the width L5 of one door leaf, but the door leaf of one car 1 cannot be moved to extend to the working position of the other car 1 to interfere with the car 1 on the other main rail.

[0064] In the embodiment, two door leaves are provided, which are door leaf one 91 and door leaf two 92 as shown in Figure 6 and 7 The door leaf one 91 and the door leaf two 92 are arranged in parallel and staggered. The door leaf one 91 can be bidirectionally moved along a straight line one, the straight line one is located in the plane where the door leaf one 91 is located, the door leaf two 92 can be bidirectionally moved along a straight line two, the straight line two is located in the plane where the door leaf two 92 is located, and the straight line one and the straight line two are parallel.

[0065] The door leaf one 91 is closer to the inside of the car 1 than the door leaf two 92. One side of the door leaf one 91 is connected to one end of the side wall of the car 1, and the other side of the door leaf one 91 is connected to one side of the door leaf two 92. Specifically, the one side of the door leaf one 91 can be attached to or have a gap with the one end of the side wall of the car 1, and the other side of the door leaf one 91 can be attached to or have a gap with the one side of the door leaf two 92.

[0066] Based on the above structure, when the car door 2 is closed, the door leaf one 91 and the door leaf two 92 of each first car door 9 have no overlapping part. Specifically, one end of the door leaf one 91 of one first car door 9 is connected to one end of one side wall of the car 1, and the other end is connected to one end of the door leaf two 92, and the other end of the door leaf two 92 is connected to one end of the other door leaf two 92. The two first car doors 9 are symmetrically arranged, so as to realize the covering and closing of the entrance and exit of the car 1.

[0067] When the car door 2 is opened, the door leaf one 91 and the door leaf two 92 of each first car door 9 at least partially overlap, preferably, the door leaf one 91 and the door leaf two 92 of each first car door 9 substantially completely overlap, and the door leaf one 91 and the door leaf two 92 are located on the side of the side wall of the car 1 away from the inside of the car 1, so as to completely expose the entrance and exit of the car 1. The movement speed, direction and stroke of the door leaf one 91 and the door leaf two 92 are determined by the driving electric shock.

[0068] The switching of the opening and closing state of the car door 2 is completed by the straight line movement of the door leaf one 91 and the door leaf two 92.

[0069] Embodiment two

[0070] As shown in Figures 8-12As shown, the car door 2 is a flexible door. Specifically, the car door 2 is flexible. When the car door 2 is closed, the car door 2 covers the entrance and exit of the car 1, forming a closure of the car 1. When the car door 2 is opened, the car door 2 moves along the outer side wall of the car 1, and during the movement, the part of the car door 2 moving out of the entrance and exit of the car 1 remains adhered to the outer side wall of the car 1 or remains parallel to the side wall of the car 1, that is, the car door 2 can "turn".

[0071] In this embodiment, the car door 2 is a second car door 10. The second car door 10 includes a plurality of long strip-shaped door blocks 101 and a plurality of hinged rods 102. The plurality of door blocks 101 are sequentially and parallelly arranged to form the body of the car door 2 of the car 1, and preferably, the door blocks 101 are perpendicular to the car roof or the car bottom, and the two ends of adjacent door blocks 101 are hinged by the hinged rods 102, that is, the two ends of the hinged rods 102 are respectively hinged to one end of two adjacent door blocks 101. Preferably, the hinged rods 102 are hinged at the end of the door blocks 101.

[0072] The top of the car 1 is provided with a guide rail 103, or the top and bottom of the car 1 are provided with guide rails 103. The guide rail 103 is L-shaped, U-shaped or mouth-shaped. When the guide rail 103 is L-shaped, the guide rail 103 includes a first L-shaped guide rail part and a second L-shaped guide rail part integrally connected into an L shape, the first L-shaped guide rail part is perpendicular to the side wall of the car 1, or parallel to the plane where the entrance and exit of the car 1 are located, and the second L-shaped guide rail part is parallel to the side wall of the car 1. When the guide rail 103 is U-shaped, the guide rail 103 includes a first U-shaped guide rail part and two second U-shaped guide rail parts connected into a U shape, the first U-shaped guide rail part is perpendicular to the side wall of the car 1, and the two second U-shaped guide rail parts are respectively parallel to the side wall of the car 1. When the guide rail 103 is mouth-shaped, the guide rail 103 includes four guide rail parts sequentially connected into a closed loop, of which two guide rail parts are perpendicular to the side wall of the car 1, and the other two guide rail parts are parallel to the side wall of the car 1.

[0073] When only the top of the car 1 is provided with the guide rail 103, the upper end of the door block 101 is provided with a guide block which can slide or roll along the guide rail 103. When the top and bottom of the car 1 are provided with the guide rails 103, the upper end and the lower end of the door block 101 are provided with guide blocks, and the guide blocks at the upper end and the lower end respectively move along the guide rails 103 at the top and the bottom of the car 1.

[0074] Based on the above structure, when a certain door block 101 moves, it will link other door blocks 101 to move through the plurality of hinged rods 102. The single door block 101 is rigid, and the plurality of door blocks 101 sequentially turn through the corner between the entrance and exit of the car 1 and the side wall of the car 1, forming the flexible effect of the car door 2.

[0075] Preferably, the door block 21 is driven to move by a driving motor. Specifically, the driving motor drives the door block 21 to move through a transmission mechanism. The transmission mechanism includes a synchronous belt and four guide wheels, the four guide wheels are rotatably mounted on the four corners of the top of the car 1, and the planes on which the guide wheels are located are parallel to the top of the car 1. The synchronous belt is sleeved on the four guide wheels, and the four guide wheels tension the synchronous belt. One end of the door block 21 is pressed or engaged with the synchronous belt. In use, the driving motor is connected to and drives at least one guide wheel to rotate, the guide wheel drives the synchronous belt to rotate, and the synchronous belt drives the door block 21 to move along the guide rail 103, thereby achieving the opening and closing of the car door. The start and end of the movement of the car door 2 are controlled by the start and end of the stroke of the driving motor.

[0076] Embodiment Three

[0077] As shown in the drawings, the car door 2 is a side opening type. Specifically, the car door 2 includes a third car door 11 and a driving mechanism. Figures 13-17

[0078] The driving mechanism includes two parallel and spaced apart tracks 111, two parallel and spaced apart connecting rods 112, and two parallel and spaced apart rocker arms 113.

[0079] The tracks 111 are fixedly mounted on the top of the car 1, and preferably, the two tracks 111 are symmetrically arranged with respect to a center line of the top of the car 1.

[0080] One end of each of the two connecting rods 112 is slidably arranged on the two tracks 111, and the other end is hingedly connected to the upper end of the third car door 11. Preferably, the connecting rods 112 are hingedly connected to the top of the third car door 11, and the two hinged connections of the two connecting rods 112 with the third car door 11 are symmetrically arranged with respect to a center line of the top of the third car door 11.

[0081] One end of each of the two rocker arms 113 is hingedly connected to the top of the car 1, and the other end of each of the two rocker arms 113 is hingedly connected to the middle of each of the two connecting rods 112. Preferably, the two hinged connections of the two rocker arms 113 with the top of the car 1 are symmetrically arranged with respect to a center line of the top of the car 1. The two hinged connections of the two rocker arms 113 with the top of the car 1 are respectively on the straight lines on which the two tracks 111 are located.

[0082] Based on the above structure, when the two rocker arms 113 are respectively collinear with the two tracks 111, the two connecting rods 112 are also respectively collinear with the two tracks 111, at this time, the third car door 11 covers the entrance and exit of the car 1, that is, at this time, the car door 2 is closed. When one end of each of the two connecting rods 112 moves along the two tracks 111 in a straight line, the moving direction is towards the entrance and exit of the car 1, the two rocker arms 113 are respectively rotated, the two connecting rods 112 are pushed, and the third car door 11 is translated along a fixed track, and the third car door 11 is translated to be away from the entrance and exit of the third car door 11, so that part of the entrance and exit of the third car door 11 is exposed or even completely exposed.​

[0083] In order to reduce the cross-sectional area of the shaft, or to enable the existing shaft to install multiple car parallel elevators. Preferably, when the car door 2 of the car 1 on one main rail is opened, the third car door 11 moves towards the direction of the other main rail. Specifically, the car door 2 drives the two rocker arms 113 to rotate at the same speed in a certain angle range, and the third car door 11 moves towards the designated side of the car 1. At this time, if there is a car 1 on the other main rail at the same floor, its car door 2 cannot be opened.

[0084] Further, in order to enable the opened third car door 11 not to affect the operation of the car 1 on the other main rail, in the direction perpendicular to the third car door 11, there is a displacement before and after the third car door 11 is opened, and the displacement distance is greater than the thickness a of the third car door 11. In other words, when there are two cars 1 at the same floor, the two cars 1 are located on two main rails, and when the car doors 2 of the two cars 1 are closed, the two car doors 2 are located in the same plane. When the car door 2 of one car 1 is opened and the car door 2 of the other car 1 is opened, the two car doors 2 at least partially overlap, and the opened car door 2 is located between the hall door and the closed car door 2. The starting point and the ending point of the movement of the car door 2 can be controlled by controlling the starting and ending points of the stroke of the drive motor.

[0085] In order to meet the requirement that the displacement of the third car door 11 in the direction perpendicular to the third car door 11 is greater than the thickness a of the third car door 11, as shown in Figure 18 The length of the rocker arm 113 and the connecting rod 112 needs to meet the following formula:

[0086]

[0087] Wherein, L1 is the length of the rocker arm 113; L3 is the distance from the hinge point of the connecting rod 112 and the rocker arm 113 to the hinge point of the connecting rod 112 and the car door 2; L2 is the difference between the total length of the connecting rod 112 and L3; S is the displacement of the third car door 11 in the direction parallel to the third car door 11. When it is required to open the third car door 11 and the entrance and exit of the car 1 are completely exposed, the value of S is greater than the width of the third car door 11.

[0088] Finally, it is necessary to point out that the above examples are only used to further illustrate the technical solutions of the present application and cannot be understood as limiting the protection scope of the present application. Some non-essential improvements and adjustments made by those skilled in the art based on the above content of the present application all belong to the protection scope of the present application.
