Fig. 1 (a) -1 (b), fig. 2, illustrate a preferred embodiment of the elevator system of the present application. The system comprises a hoistway 1 and a plurality of cabs 2 which are arranged in the hoistway 1 and can be unfolded, contracted and folded, wherein the hoistway 1 comprises a working operation hoistway area 11 which allows the cabs 2 after being unfolded to be arranged up and down and simultaneously run, and a waiting operation hoistway area 12 which is arranged behind the working operation hoistway area 11 and is used for the cabin 2 after being contracted and folded to be sequentially arranged up and down for accommodating, at least one group of heavy-duty steel rail systems 3A are arranged in the working operation hoistway area 11 and are fixed on the side wall of the working operation hoistway area 11, at least one group of light-duty steel rail systems 3B are arranged in the waiting operation hoistway area 12 and are fixed on the rear wall of the waiting operation hoistway area 12, a driving mechanism 22 for driving the cabs 2 to be unfolded or contracted and folded is arranged at the bottom of the cabs 2, and a light-duty operation system is arranged at the end part of the driving mechanism 22 and can be meshed with the light-duty steel rail systems 3B in the folding and contracting or expanding process of the cabs 2; the side of the car 2 is provided with a heavy-duty running system which can be engaged with the heavy-duty steel rail system 3A. The drive mechanism may be a curved translational telescopic arm that can power the deformation of the car 2, which is retracted at the bottom of the car 2 when the car 2 is in operation, which curved translational telescopic arm can power the deformation of the car 2, as will be explained later.
It should be noted that the driving mechanism 22 may be disposed on the top of the car 2, and in this case, the deformation directions of the top and bottom surfaces of the car are opposite to the direction when the driving mechanism 22 is disposed at the bottom of the car 2, but this does not affect the effect. It should be noted that, in combination with the habit and factors, it may be more appropriate to use a design in which the driving mechanism 22 is located at the bottom of the car 2.
The car 2 is square, between the first side 25, the second side 26, the car top 23 and the rear side 28 of the car 2, and between the lower side of the car door 27 frame and the car bottom 21, the car door 27 is mechanically rotated and connected, the car door 27 is horizontally moved in the car door frame to realize opening and closing, the upper side of the car door 27 frame is fixedly connected with the car top 23, the car bottom 21 and the rear side 28, the car bottom 21 and the car top 23 are movably connected by a first surface 201 and a second surface 202 respectively through at least one limiting hinge 29, the limiting hinge 29 is arranged close to the rear side 28 and the car door 27 respectively, and the core shaft of the limiting hinge 29 is parallel to the horizontal sliding direction.
In this embodiment, the first side 25, the second side 26, the space between the car top surface 23 and the rear side 28, and the car bottom surface 21 are all rotatably connected to the lower side of the door frame of the car door 27 through the limit rotating shaft 20. The limiting rotating shaft 20 can keep the current state of the car 2 under the mechanical limiting effect, and when the car 2 runs, the first side face 25, the second side face 26 and the like can keep the corresponding unfolding state when running, and when the car does not work and fold, the car can provide good rotating force and maintain the folding state, so that the safety performance is good. Meanwhile, the design can ensure effective connection among all parts of the car body to form an organic whole, and further ensure the effectiveness of telescopic deformation.
The first side 25 and the second side 26 can rotate relative to the rear side 28 and fold to the rear side 28 in turn, the car top 23 and the car bottom 21 can rotate in the same direction relative to the rear side 28 in the vertical direction when the driving mechanism 22 provides deformation power, and the car door 27 is driven to shift to the corresponding position under the action of the limit hinge 29 and the mechanical rotation, so that the car 2 is folded and deformed from a box body in a working state to a contracted state or deformed from a folded and contracted state to a working expansion state, namely, the car 2 is deformed and switched between the working expansion state and the waiting folding state under the combined action of the driving mechanism 22 and the light load steel rail system 3B and the heavy load steel rail system 3A and the heavy load operation system, is translationally switched between the working operation well region 11 and the waiting operation well region 12 and is operated in the waiting operation well region 12, and the mutual switching between the working operation well region 11 and the waiting operation well region 12 is realized, and the car 2 is enabled to enter respective operation modes, so that the working operation well region is converted to be convenient for other cars to normally run or the working state to be switched to the working state to meet the requirement of the passenger well.
When the working state body is compressed into the waiting state body, the upper side of the car door frame is fixedly connected with the car top surface, the car bottom surface and the rear side surface, so that when the car door frame is finally folded under the cooperation of the limiting hinge to form a flat cuboid, the occupied space is greatly reduced, and the car door frame is convenient to place in the waiting operation well region 12, and the car door frame is particularly shown in fig. 4 (a) -4 (c). Of course, the horizontal distance between the limit hinge and the car door and the rear side surface determines the rectangular size of the final state, and the horizontal distance is preferably 10-20 cm in order to save more space.
When the driving mechanism 22 is a bending translation telescopic arm, as the driving mechanism has a translation telescopic function, the arm lever can be bent and lifted, namely, turned over, and the action can generate acting force on the bottom surface of the car, so that the limit rotating shafts 20 on the top surface of the car and the bottom surface of the car are driven to rotate with force, and further the top surface of the car and the bottom surface of the car are driven to rotate in the same direction in the vertical direction, and folding is realized; when the folding state is extended to the working state, the driving mechanism 22 gradually returns to the flat state, the so-called turning action is gradually removed, the top surface and the bottom surface of the car rotate back under the action of self gravity, and the action on the limiting rotating shaft 20 and the limiting hinge 29 is gradually reduced, so that the two side surfaces, the car door and the like are gradually returned to the working unfolded state. Of course, the arm turning function of the bending translation telescopic arm can be realized in other manners, such as an electric driving manner, a hydraulic driving manner and the like.
For safety, the heavy-duty running system comprises a heavy-duty gear set system 4A and a brake braking mechanism (the brake braking mechanism is not shown in the figure), and the driving mechanism 22 is connected with a light-duty steel rail system 3B through a light-duty running system arranged at the end of the heavy-duty running system, that is, the light-duty running system comprises a light-duty gear set system 4B and a brake braking mechanism (the brake braking mechanism is not shown in the figure). The heavy-load gear set system 4A and the light-load gear set system 4B are respectively provided with a power supply and information receiving system 5, and the heavy-load steel rail system 3A and the light-load steel rail system 3B are correspondingly provided with a power supply and information granting system 6 coupled with the power supply and information receiving system 5.
The heavy-duty gear train system 4A is similar to the light-duty gear train system 4B in structure, and the heavy-duty rail system 3A is similar to the light-duty rail system 3B in structure, so the heavy-duty gear train system 4A and the heavy-duty rail system 3A will be described below as examples.
Referring to fig. 3 (a) -3 (c), the heavy-duty gear set system 4A includes a first wall 431, a second wall 432, and a gear 41 disposed between the first wall 431 and the second wall 432 in a transverse rotation manner, where the dimensions of the first wall 431 and the second wall 432 are larger than the diameter of the gear 41, and one end side surface of the first wall 431 and the corresponding end side surface of the second wall 432 are both provided with the power supply and information receiving system 5, and the one end side surface and the corresponding end side surface are formed by bending in opposite directions.
Correspondingly, the heavy-load steel rail system 3A is a steel rail 32 with a rack 31 arranged on the surface, the steel rail 32 is meshed with the gear 41 through the rack 31, two sides of the steel rail 32 are concaved inwards to form a groove body in which one end side surface and the corresponding end side surface can be respectively embedded and clasped, and the power supply and information granting system 6 is positioned in the groove body. The corresponding end side surfaces of the first wall and the second wall can tightly clamp the steel rail through the groove body, so that a strong balance force is provided for the elevator car, and the overall balance of the elevator car can be ensured even if a gear set system is arranged on one side of the elevator car. Meanwhile, a locating hole 33 for locating the car 2 on a corresponding floor and a falling preventing hole 34 for braking when the car 2 falls are also arranged in the groove body of the steel rail 32.
When the heavy-duty gear set system 4A on the car 2 is engaged with the heavy-duty steel rail system 3A in the working state, the power supply and information receiving system 5 and the power supply and information granting system 6 are coupled and distributed simultaneously. When the car 2 moves to a designated station, namely to a corresponding floor, the car is meshed with the positioning holes 33, and is released during operation, if the car 2 falls under special conditions, the heavy-duty gear set system 4A can search the nearest falling-preventing holes 34 below in the falling process to ensure the braking safety.
In this embodiment, the heavy-duty gear set system 4A has four groups, and after being equally divided, the heavy-duty gear set system 4A is correspondingly located on the first side 25 and the second side 26, the driving mechanism 22 has two groups and is parallelly disposed at the bottom of the car 2 and moves synchronously, the light-duty gear set system 4B also correspondingly has two groups, and the multiple gear set systems mean that the multiple gear set systems are matched with the steel rail systems, that is, multiple guarantees are provided, so that the safety of the up-and-down operation and the operation for the waiting after the folding deformation of the car is improved.
If the car fails in operation, the car can automatically slowly descend to the nearby lower floor, and the door can be automatically opened. A temporary operation zone can be automatically formed on more than the upper floor of the floor, and a temporary operation zone can be automatically formed on the lower floor of the floor, so that even if a current car fails, other area elevators can normally work in the temporary operation zone, and the whole working operation well area is not in a paralysis state. Also based on this consideration, the running pitch of the cars is at least not less than one floor height, and the total number of cars 2 running in the working running shaft region 11 needs to be less than one third of the floors.
Of course, the elevator system further comprises other devices, such as a first wall 431 and a second wall 432, a first power and safety detection system 45 for controlling the gear 41 to operate is further provided, and a second power and safety detection system 30 is correspondingly provided at the bottom of the car 2.

Combining the schematic diagrams (a) - (e) in fig. 5 with fig. 7, when the car 2 receives an avoidance or waiting instruction after finishing working operation, the car is automatically checked, if abnormal conditions exist, information processing is immediately fed back, and if personnel or articles are detained in the car, voice prompt or alarm can be carried out; if the situation is normal, the driving mechanism 22 extends, namely the bending translation telescopic arm extends and drives the light load gear set system 4B to be meshed with the light load steel rail 3B to take electricity and receive information, the heavy load gear set system 4A on the lift car 2 can be automatically separated from the heavy load steel rail 3A when the detection situation is normal, the lift car 2 is translated into the waiting operation well region 12 by the working operation well 11, the limiting rotating shaft 20 sequentially rotates to enable the first side face 25 and the second side face 26 to be sequentially attached to the rear side face 28 in parallel, and when the lift car is translated into place after attachment is in place, if the detection is normal, the driving mechanism 22, namely the bending translation telescopic arm drives the limiting rotating shaft 20 to enable the lift car body to be deformed into a rhombus and finally to be in a flat cuboid, and after the deformation is finished, the waiting operation well region can be moved in the fifth step through the detection is normal.
If the car 2 receives a working instruction in the waiting operation well region 12, as shown in (a) - (e) in fig. 6 and fig. 8, the car is automatically and safely checked, if abnormal conditions are immediately fed back to the information processing, if the conditions are normal and immediately upward or downward to the corresponding positions, the driving mechanism 22, namely the bending translation telescopic arm, can turn the arm rod to drive the rotating shaft 20 to deform the flat cuboid car into a rhombus, the flat cuboid car is gradually changed into a square, then if the detected conditions are normal, the driving mechanism 22, namely the bending translation telescopic arm, can enable the car 2 to translate from the waiting operation well region 12 into the working operation well region 11, meanwhile, the second side 26 and the first side 25 are sequentially rotated under the action of the rotating shaft 20 to return to the original working positions from the rear side 28, the heavy load gear set system 4A is meshed with the heavy load gear set system 3A to take electricity and receive information after the translation and the transition, and when the detection conditions are normal, the light load gear set system 4B on the driving mechanism 22, namely the bending translation telescopic arm on the car 2 can automatically retract to the light load gear set system 3B and the light load gear set system 21 back to the car bottom surface 21 when the detected conditions are normal, and the car is normally disengaged from the working well region 2, and can be normally put into operation into the working operation region after the detection.
