An elevator system operating method comprising the steps of:

step 1, a passenger selects a destination floor to go ahead at a current floor, and an elevator system receives a command of the passenger; wherein

If a stopping car mechanism is arranged on the transfer platform of the current floor, the car mechanism enters a loading area of the transfer platform of the current floor, and a car door of the car mechanism is opened;

if the car mechanism does not stop on the transfer platform of the current floor, the car mechanisms of other floors move to the current floor from the ascending channel or the descending channel, move into the loading area of the transfer platform of the current floor from the ascending channel or the descending channel, and open the car doors;

and 4, moving the car mechanism into a loading area of a transfer platform of a target floor, opening a car door, and enabling passengers to leave the car mechanism.

Preferably, the transfer platform further includes a standby zone in which the car mechanism in the stopped state is stopped.

Compared with the prior art, the invention has the following advantages:

(1) high operation efficiency and short waiting time

According to the invention, a plurality of lifting platforms and the lift car can be operated simultaneously in one elevator system, and processes of passenger getting on and off, car door opening and closing and the like which take relatively much time can be carried out on the transfer platform through the movement of the lift car between the lifting platforms and the transfer platform, so that the influence of the processes on the continuous motion of the lifting platforms is avoided; because the car mechanism 1 (light car) is adopted, the space is smaller than that of the existing elevator car, and the number of passengers is small, so that the time spent by the passengers in and out of the car is also small; the car only goes to one destination floor every time, and the car can not stop as passengers on other floors need, so that frequent starting and stopping are not needed in midway.

When the passengers use the elevator, if the current floor transfer area has a car to stop, the passengers can directly use the car of the floor, and if the current floor transfer area has no car, a plurality of lifting platforms which circularly run in the system can quickly send the empty car to the current floor for the passengers to use; the ascending and descending processes of the elevator are respectively completed in the ascending and descending channels, so that the situation that passengers need to take the elevator to go down the floor and the elevator just goes upward is avoided, and the similar situations that passengers need to wait for the elevator car to return from the top floor and can take the elevator car are further avoided.

(2) Better passenger experience

The car mechanism 1 (light car) is adopted, the capacity of the car is less than 4 persons, the independent space and privacy of passengers can be ensured, and the problems of crowding, smell, harassment and the like caused by the riding of a plurality of persons are avoided; the elevator car can directly send passengers to a target floor, so that physical discomfort and dysphoria caused by repeated starting and stopping are avoided; the waiting time is short, the running speed is high, and the time of passengers can be effectively saved.

(3) Better safety

The outer door of current elevator is opened the back and is directly just dark elevartor shaft, in case the outer door of elevator is opened because reasons such as external force or system trouble, and the personnel that get into will directly fall to the elevartor shaft depths, does not have lifelike possibility basically. However, in the elevator, the transfer platform is arranged in the outer door of the elevator, and the movable railings between the transfer platform and the lifting channel are generally lifted (only the car needs to be moved into the lifting platform and then is lowered), so that even if a person enters the elevator shaft from the outer door, the person is blocked, and even if the person falls into the lifting channel, the person can fall on the lifting platform in a short distance, so that the injury is reduced.

The car dead weight of current elevator is great, and the number of holding is also more, and in case traction system breaks down, the car drops fast very easily, still can drop the certain distance before car safety device plays a role, and the passenger can only wait for external rescue under this kind of condition. However, the total weight of the elevator car and passengers is smaller, the elevator car is driven to move up and down by the lifting platform running on the lifting track, the possibility of falling of the elevator car is greatly reduced, even if the lifting platform fails and cannot brake, the car can be blocked by other lifting platforms at short distances to prevent the car from continuously falling, and then the accident car can be pushed to return to a safe floor by other lifting platforms, so that the passengers can get rid of the trouble by themselves.

(4) Low construction cost, low power consumption and more convenient maintenance

The system adopts the lifting platform to push the lift car to move up and down, so that only the bottom plate of the lift car needs to bear the pressure from passengers, and other surfaces are basically free from stress, so that the lift car can be made of light materials and has low strength requirement, and the manufacturing cost of the lift car is greatly reduced; the total weight of the lift car and passengers transported by each lifting platform at one time is smaller, the power of a driving motor in a main power module of the lifting platform is smaller than that of a traction device of a traditional elevator, and complex mechanisms such as a traction steel cable and a safety device are not needed.

The self weight of the lift car is light, so that the problem of energy waste caused by the fact that a lift car with the self weight exceeding one ton is used for conveying one passenger (weighing dozens of kilograms) upstairs and downstairs in the conventional lift system is solved; the lift platform directly sends the lift car and passengers to a target floor, and energy waste caused by frequent start and stop of the lift car is avoided; the car in the standby state stops on the transfer platform and does not need to consume electric power.

When the lift car is maintained or maintained, the lift car can be moved to the transfer platform or directly moved out of the elevator shaft, so that the maintenance or maintenance work is greatly facilitated, and the normal operation of the system cannot be influenced; when the lifting platform is maintained, the lifting platform can be detached from the track and then maintained, so that the time consumption of the whole process is short, and the influence on the operation of the system is small; the lifting platform can be directly moved to the outside of an operation area for maintenance by arranging modes such as lifting track branch circuits, turnouts and the like, and the system operation cannot be influenced.

(5) More flexible construction and operation

In construction, the size of the elevator shaft opening required by the invention is smaller than that of the existing elevator system, so that the damage to the building structure can be reduced; the elevator system on different floors can be constructed at different positions in a staggered manner by adopting the lifting platforms to drive the elevator cars to move, and all the lifting platforms and the elevator cars can be used in different sections (the lifting platforms move through the rails and the elevator cars move through the elevator cars); the spatial arrangement modes of the ascending channel, the descending channel and the transfer platform are flexible, and the influence of the construction of the conventional elevator system on the aspects of lighting, ventilation, configuration and the like of a building is greatly reduced.

In the operation process, when the transport capacity of the system is tense, the lifting platform can be added into the system through the lifting track branch, and when the transport capacity of the system is excessive, the lifting platform can be removed from the system through the lifting track branch, so that the waste of electric power and the loss of idle running of the system are prevented; according to the use frequency and the number of people of the elevator systems in the building, two passages (ascending and descending) of one elevator can be selected to respectively convey passengers to go upstairs and downstairs, two adjacent elevator systems can be used to respectively convey passengers to go upstairs and downstairs, more elevator systems can be operated in a combined mode, and cars between different systems can be freely allocated according to needs to provide larger transportation capacity and faster response speed.

Detailed Description

The present invention will now be described in further detail, with the understanding that the present invention is to be considered as illustrative and not restrictive. The invention is further described below with reference to the accompanying drawings.

As shown in fig. 1 to 11, the present invention relates to an elevator system which is composed of a car mechanism 1 (light car), a lifting rail 2, a lifting platform 3, a transfer platform 4, an elevator shaft 5, a control mechanism 6, and the like, and the structures and functions of the respective parts are as follows.

The car mechanism 1 (light car) is a member for loading passengers, and is mainly composed of a car housing 7, a car door 8, a car floor 9, a two-dimensional traveling mechanism 10, and a power take-out device 11. The car shell 7 comprises walls on the periphery and the top of the car, the car door 8 can be opened to allow passengers to enter and exit the car, the car bottom plate 9 is used for supporting the weight of the car and the passengers and is provided with a two-dimensional walking mechanism 10 and a power taking device 11, the two-dimensional walking mechanism 10 is used for realizing the front-back and left-right movement of the whole car in a plane and driving the car door 8 to open and close simultaneously, and the power taking device 11 is used for obtaining electric power from a platform where the car is located to allow the two-dimensional walking mechanism 10 to use.

The lifting rail 2 is a rail on which the lifting platform 3 runs, and structurally comprises a main rail 12, a sub-rail 13, a lifting power supply belt 14 and a movable guardrail 15. The main rail 12 and the auxiliary rail 13 are fixed to the wall surface of the elevator shaft 5, and together support the lifting platform 3, the main rail 12 also interacts with the lifting platform 3, thereby enabling the lifting platform 3 to ascend and descend. Also embedded in the main track 12 are elevator power supply belts 14 which draw power from cables laid in the hoistway walls and provide it to the elevator platform 3. The movable guardrail 15 is installed on the outer side face of the auxiliary rail 13, and rises when the car does not enter the lifting channel, so that personnel can be prevented from entering the lifting channel, and the limiting effect on the car can be achieved. According to the running direction of the lifting platform 3 on the track, the lifting track 2 can be divided into 4 functional partitions such as an ascending channel 21, an upper revolving channel 22, a descending channel 23 and a lower revolving channel 24, wherein the ascending channel 21 is used for ascending the lifting platform 3, the descending channel 23 is used for descending the lifting platform 3, the lifting platform 3 completes one-time overturning action through the upper revolving channel 22 and enters the descending channel 23, and similarly, the lifting platform 3 overturns once through the lower revolving track section and enters the ascending channel 21 again.

The lifting platform 3 is used for pushing the car mechanism 1 (light car) to ascend or descend along a channel and is a key part for realizing the rapid lifting cycle work of the elevator system. The lifting platform 3 mainly comprises a main power module 16, an auxiliary support 17, a bearing flat plate 18, a fixed limiting block 19 and a movable limiting block 20. The main power module 16 can take power from the track and also interact with the main track 12 to drive the lifting platform 3 to move, and at the same time can automatically and rapidly brake in abnormal situations such as power failure. The secondary support 17 interacts with the secondary track 13 and functions to support the lifting platform 3. The load-bearing plate 18 is a load-bearing member for supporting the car, and a power supply belt is embedded in the surface thereof and can transmit electric power to the power-taking device 11 of the car. From the appearance and the structure, the whole lifting platform 3 is symmetrical up and down, so that the lifting platform can adapt to two working states of ascending and descending.

The transfer platform 4 is a transfer area of the car mechanism 1 (light car) in the states of passenger access and car standby, is directly installed or arranged on the ground corresponding to floors, a transfer power supply belt is also embedded on the upper surface of the transfer platform 4, the electric power can be transmitted to the car to get the power device 11, and the transfer platform 4 is also provided with a limiting device corresponding to different stop positions of the car mechanism 1 (light car). The transfer platform is generally divided into two functional sections, i.e., a loading area 41 (a car parking area when passengers get in and out) and a standby area 42 (a car parking area in an idle state), and may be both the loading area 41.

The elevator shaft 5 is a space for installing the whole elevator system in the building, and is also a shell and a boundary of the whole elevator system, an elevator outer door is installed on one side facing the transfer platform 4 and linked with the opening and closing action of the car door 8 for passengers to get in and out of the elevator, and a control panel is also installed near the elevator outer door of each floor. A space corresponding to the ascending path 21 of the ascending rail 2 in the elevator shaft 5 is an ascending path 21, and a space corresponding to the descending path 23 is a descending path 23.

The control mechanism 6 controls the operation of the whole elevator system by acquiring the state parameters of all the components and sending related control commands, and the control mechanism 6 comprises a control server, a control panel arranged outside the elevator door of each floor, sensors arranged on other components, action components and the like on hardware. The main functions that the control mechanism 6 can perform include: controlling the movement and stop of the car mechanism 1 (light car) on different platforms and between the platforms, controlling the opening and closing of the car door 8 and the elevator outer door, controlling the rising and falling of the movable fence 15, controlling the moving speed and the stop position of the lifting platform 3 on the lifting rail 2, controlling the action of the movable stopper 20, and the like.

The operation of the elevator system will be described below by taking the process of a passenger going upstairs as an example:

(1) passengers directly select a destination floor to go to on an elevator control panel of a certain floor, the destination floor is higher than the current floor, if no car stops in the standby area 42 of the transfer platform of the current floor, the cars stopping in the standby areas 42 of other floors reach the current floor through the lifting platform 3 in the descending passage 23, and then the cars move into the standby areas 42;

(2) after the car in the standby area 42 moves into the loading area 41 and stops at a certain position, the car door and the outer door of the elevator are opened successively, passengers enter the car, and meanwhile, the nearest idle lifting platform 3 in the ascending channel 21 quickly ascends and stops at the current floor;

(3) after the passenger enters the car, the car door and the outer door are closed successively, and when the lifting platform 3 is in place at the current floor, the movable handrail descends, and the car moves into the lifting platform 3 from the loading area 41;

(4) after the lift car moves into the lifting platform 3, the movable limiting block fixes the lift car, the movable guardrail 15 rises, and then the lifting platform 3 begins to rise;

(5) after the lifting platform 3 stops to a target floor, the movable limiting block 20 releases the limiting, the movable guardrail 15 of the target floor descends, the lift car moves into the loading area 41 of the transfer platform of the target floor from the lifting platform 3, then the movable guardrail 15 rises, and the idle lifting platform 3 continues to rise along the lifting track 2;

(6) the outer door and the car door are opened successively, and passengers leave the car;

(7) if no passengers are departing from the destination floor, the car moves into the standby area 42 and waits for a system call or other floor to be reached via the landing 3 in the descent passage 23.

(8) Thus, the process of transporting passengers upstairs is completed once, and if the passengers downstairs from a certain floor, the whole process is basically similar, and the loading area 41 and the standby area 42 are only required to be exchanged.

When the left and right partitions of the transfer platform 4 are the loading areas 41, it is indicated that the doors can be opened to let passengers get in and out of the car when the car stops at the left and right sides of the transfer platform 4, and the two loading areas 41 are used for passengers going upstairs and downstairs to get in and out respectively. At this time, the corresponding workflow is basically consistent with the original workflow, and the main difference is as follows: in step 1, if a car mechanism stops at a transfer platform 4 (any one of the left and right loading zones 41) of the current floor, the car mechanism moves from a stopping position to the loading zone 41 corresponding to the upstairs or downstairs of passengers, namely, the car translates to the loading zone 41 corresponding to the ascending channel when the passengers go upstairs, and the car translates to the loading zone 41 corresponding to the descending channel when the passengers go downstairs, and then the car mechanism opens a car door; if there is no car stopping at the transfer platform 4 at the current floor, the car mechanism at the other floor moves from the ascending or descending path to the current floor, moves from the ascending or descending path into the corresponding loading zone 41 of the transfer platform 4 at the current floor, and then opens the car door.

When the elevator system is built, elevator shafts can be built on the same straight line from top to bottom in a building, elevator shafts of different floors can be built at different positions, and the elevator shafts can be built at a certain inclination angle.

For the position arrangement and the number of the ascending channel 21, the descending channel 23 and the transfer platform 4 of the elevator system, various different combination modes can be adopted, the conventional arrangement mode is that four subareas are arranged according to a Chinese character tian, the ascending channel 21 and the descending channel 23 can be respectively built on two sides of the transfer platform 4, or the transfer platform 4 is set to be a standby zone 42 between two loading zones 41.

Air openings can be formed in the bottom plate 9 and the wall surface of the car to ensure air circulation in the car; the cross section of the car can be square, can be circular, can also design the car into other shapes.

An air opening can be opened or a fan can be arranged on the bearing flat plate 18 of the lifting platform 3, so that the air circulation in the lift car can be ensured, and the air resistance of the lifting platform 3 during the up-and-down movement can be reduced.

The ascending channel 21 and the descending channel 23 of one elevator system can be used for respectively conveying passengers upstairs and downstairs, namely, the independent operation mode is adopted; it is also possible to transport passengers upstairs and downstairs with two or more elevator systems adjacent to each other, respectively, the cars being freely transferable as required and used in different systems, i.e. in a combined mode of operation.

The foregoing description of specific embodiments of the present invention has been presented. It is to be understood that the present invention is not limited to the specific embodiments described above, and that various changes or modifications may be made by one skilled in the art within the scope of the appended claims without departing from the spirit of the invention.
