[0027] There are a large number of old residential areas without elevators, which makes it inconvenient for the elderly or people with limited mobility to go up and down the stairs, posing a safety risk. The cost of installing elevators is high, and the structure of old and small residential areas cannot fully meet the requirements for installing elevators. The cost of installing outdoor elevator shafts or corridors is even higher, and it affects lighting, later operation and maintenance costs, etc. Therefore, elevators can be installed in pedestrian stairwells.

[0028] Among the existing solutions for installing elevators in pedestrian stairwells, some are installed on the stair handrails, and the elevators run along the stair handrails. The technical solution of installing the elevator on the stair handrails will result in insufficient support of the elevator, and there are problems with safety and inconvenience in use; some are to install the elevator on the wall of each floor of the stairs. This technical solution is costly, some technical solutions cannot run continuously, and it is difficult to arrive in one stop, and some technical solutions have the problem of inconvenient turning, and will also occupy a large amount of the original walking space of the pedestrian stairs.

[0029] To this end, an embodiment of the present invention provides a straight-track inclined automatic steering hanging rail elevator car, which can carry people or goods and is convenient for going up and down stairs. During operation, the elevator car can automatically and smoothly turn and will not occupy a large space in the walking stairwell.

[0030] At least one embodiment of the present invention provides a straight-track inclined automatic steering hanging rail elevator car, which is installed in a walking stairwell. The walking stairwell includes an inclined tread of a rest platform plate. The hanging rail elevator car includes a hanger, a hanging rail, a drive assembly and an elevator frame.

[0031] The hanger includes an inclined rail hanger and a curved rail hanger. The inclined rail hanger is fixedly installed at the bottom of the inclined tread plate, and the curved rail hanger is fixedly installed at the bottom of the rest platform plate. The curved rail hanger connects two adjacent inclined rail hangers. The hanging rails include inclined hanging rails and curved hanging rails, the inclined hanging rails are connected to the inclined rail hanger, the curved hanging rails are connected to the curved rail hanger, the curved hanging rails are connected to two adjacent inclined hanging rails, and the ends of the inclined hanging rails and the curved hanging rails are staggered; The driving assembly includes a driving wheel, a driving member and a connecting frame. The driving wheel slides on the inclined hanging rail or the curved hanging rail. The driving member is used to drive the driving wheel to travel along the inclined hanging rail or the curved hanging rail. The driving member is connected to the connecting frame. The driving wheel includes a synchronous wheel and a groove wheel. When the driving assembly is located under the inclined tread plate, the synchronous wheel travels on the inclined hanging rail. When the driving assembly is located under the rest platform plate, the groove wheel travels on the curved hanging rail. The elevator frame is connected to the connecting frame. The elevator frame is located on one side of the walking staircase close to the stair handrail and is used to carry people or goods.

[0032] In the straight-rail inclined automatic steering hanging rail elevator car provided in the above-mentioned embodiment of the present invention, people or goods can be carried through the elevator frame. Driven by the driving component, the elevator frame travels along the inclined hanging rail and the curved hanging rail, which is convenient for going up and down stairs. The inclined hanging rail and the curved hanging rail are staggered at the connection point, so that the hanging rail elevator car can automatically and smoothly turn, and the inclined rail hanger and the curved rail hanger are respectively installed under the inclined tread and under the rest platform. The elevator frame is located on one side of the walking stairwell, so as not to occupy a large space in the walking stairwell.

[0033] The present invention is described below by several specific embodiments. In order to keep the following description of the embodiments of the present invention clear and concise, the detailed description of known functions and known components may be omitted. When any component of the embodiments of the present invention appears in more than one accompanying drawings, the component may be represented by the same reference numeral in each of the accompanying drawings.

[0034] like Figure 1 , Figure 2 , Figure 4 , Figure 5 As shown, an embodiment of the present invention provides a straight-track inclined automatic steering hanging rail elevator car, which is installed in a walking stairwell. The walking stairwell includes an inclined tread 1 of a rest platform board, and the hanging rail elevator car includes a hanger 3, a hanging rail 4, a drive assembly 5 and an elevator frame 6.

[0035] The hanger 3 includes an inclined rail hanger 31 and a curved rail hanger 32. The inclined rail hanger 31 is fixedly installed at the bottom of the inclined tread plate 1, and the curved rail hanger 32 is fixedly installed at the bottom of the rest platform plate. The curved rail hanger 32 connects two adjacent inclined rail hangers 31. The hanging rail 4 includes an inclined hanging rail 41 and a curved hanging rail 42, wherein the inclined hanging rail 41 is connected to the inclined rail hanger 31, and the curved hanging rail 42 is connected to the curved rail hanger 32, and the curved hanging rail 42 connects two adjacent inclined hanging rails 41, and the ends where the inclined hanging rail 41 and the curved hanging rail 42 are connected are staggered; The driving assembly 5 includes a driving wheel 51, a driving member 52 and a connecting frame 54. The driving wheel 51 slides on the inclined hanging rail 41 or the curved hanging rail 42. The driving member 52 is used to drive the driving wheel 51 to travel along the inclined hanging rail 41 or the curved hanging rail 42. The driving member 52 is connected to the connecting frame 54. The driving wheel 51 includes a synchronous wheel 511 and a groove wheel 512. When the driving assembly 5 is located under the inclined tread plate 1, the synchronous wheel 511 travels on the inclined hanging rail 41. When the driving assembly 5 is located under the rest platform plate, the groove wheel 512 travels on the curved hanging rail 42. The elevator frame 6 is connected to the connecting frame 54. The elevator frame 6 is located on a side of the walking staircase close to the stair handrail and is used for carrying people or goods.

[0036] Specifically, when installing a hanging rail elevator car, starting from the first floor, the bottom surface of the inclined tread 1 of each walking staircase is fixed with an equidistant inclined rail hanger 31, and the bottom surface of the rest platform of each walking staircase is fixed with an equidistant curved rail hanger 32. The inclined rail hanger 31 and the curved rail hanger 32 are used as the hanging rail elevator car's suspending structure, which can be anchored in the cast-in-place concrete tread at the top of the walking staircase, and the anchoring of multiple anchor points at intervals will not damage the load-bearing structure of the building, which can not only achieve the stable suspending of the hanging rail elevator car as a whole, but also help to reduce the occupation of the walking staircase space. For example, the inclined rail hanger 31 includes an anchor rod and a fixing frame. The anchor rod is connected to the cast-in-place concrete tread of the walking staircase through an expansion bolt, and the fixing frame is connected to the anchor rod through bolts to ensure that the hanger 3 is stable and the height of the fixing frame can be adjusted; the curved rail hanger 32 has a similar structure to ensure the structural safety of the elevator car.

[0037] The hanging rail 4 is connected to the hanger 3, and the hanging rail 4 includes an inclined hanging rail 41 and a curved hanging rail 42. The inclined hanging rail 41 is laid on the straight hook of the inclined rail hanger 31 fixed to the bottom surface of the inclined tread plate 1, and the curved hanging rail 42 is connected to the curved rail hanger 32 fixed to the bottom surface of the rest platform plate. The curved hanging rail 42 is designed in a semicircular or arc shape to ensure that the elevator car turns at a uniform speed and smoothly at the turning point, and the inclined hanging rail 41 is a straight upward track. The staggered design is adopted at the connection between the inclined hanging rail 41 and the curved hanging rail 42, which can enable the hanging rail elevator car to achieve uniform speed turning, thereby helping to improve the operating efficiency of the hanging rail elevator car and the stability at the turning point.

[0038] The driving assembly 5 can move along the inclined hanging rail 41 or the curved hanging rail 42, wherein the driving wheel 51 is used to travel on the inclined hanging rail 41 or the curved hanging rail 42, the driving member 52 can provide power to the driving wheel 51 so that the driving wheel 51 can travel on the inclined hanging rail 41 or the curved hanging rail 42, and the connecting frame 54 serves as an installation platform for the driving wheel 51 and the driving member 52.

[0039] Furthermore, if Figure 4 , Figure 5 , Figure 6 As shown, the driving wheel 51 includes a synchronous wheel 511 and a groove wheel 512, both of which are connected to the power output end of the driving member 52. When the driving assembly 5 is located under the inclined tread plate 1, the synchronous wheel 511 runs on the inclined hanging rail 41, and the groove wheel 512 is suspended in the air. When the driving assembly 5 is located under the rest platform board, the groove wheel 512 runs on the curved hanging rail 42, and the synchronous wheel 511 is suspended in the air. At the same time, the connection between the inclined hanging rail 41 and the curved hanging rail 42 is staggered, so that the driving wheel 51 can make a smooth transition when switching between different tracks.

[0040] It should be noted that the driving member 52 can be a motor, which usually has an output shaft. After the motor is installed in the connecting frame 54, the whole is in a "7" shape. In the present invention, the motor is modified and designed so that both ends of the motor have output shafts, and the output shafts on both sides rotate at the same time. After the motor is installed in the connecting frame 54, the driving assembly 5 is in a T shape as a whole, and the motor has a power-off brake function.

[0041] The elevator frame 6 is connected to the connecting frame 54. When the driving assembly 5 moves along the inclined hanging rail 41 or the curved hanging rail 42, the elevator frame 6 is driven to move synchronously, so that passengers or goods can be safely and efficiently transported to different floors. At the same time, the elevator frame 6 is located on the side of the walking staircase close to the stair handrail, which not only facilitates residents to go up and down the stairs, ensures safety, but also improves the utilization rate of the space in the building.

[0042] The inclined rail hanger 31 is installed at the middle position of the bottom of the inclined tread 1, and the curved rail hanger 32 is installed on the ground of the rest platform near the stair handrail, so that the inclined hanging rail 41 is directly below the inclined rail hanger 31, and the curved hanging rail 42 is directly below the curved rail hanger 32, and the driving assembly 5 will run directly below the inclined hanging rail 41 or the curved hanging rail 42. On the one hand, the anchoring effect of the inclined hanging rail 41 can be better, and on the other hand, the elevator frame 6 can occupy less stair space at the turning point to avoid interfering with normal traffic and the opening and closing of residents' entrance doors.

[0043] The elevator frame 6 is used to carry people or goods. Driven by the driving component 5, the elevator frame 6 runs along the inclined hanging rail 41 and the curved hanging rail 42, which is convenient for going up and down stairs. The inclined hanging rail 41 and the curved hanging rail 42 are staggered at the connection point, so that the hanging rail elevator car can automatically and smoothly turn, and the inclined rail hanger 31 and the curved rail hanger 32 are respectively installed under the inclined step board 1 and the rest platform board 2. The elevator frame 6 is located on one side of the walking stairwell, so as not to occupy a large space in the walking stairwell.

[0044] In an embodiment of the present invention, Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the inclined hanging rail 41 includes an inclined left hanging rail and an inclined right hanging rail which are symmetrically arranged, and a synchronous belt 411 is provided on both the inclined left hanging rail and the inclined right hanging rail, and a rack is provided on the synchronous belt 411. The curved hanging rail 42 includes an inner curved hanging rail and an outer curved hanging rail, the inner curved hanging rail is butted with the end of the inclined left hanging rail and arranged in a staggered manner, and the outer curved hanging rail is butted with the end of the inclined right hanging rail and arranged in a staggered manner; the two curved rails are located inside the two inclined rails;

[0045] The synchronous wheel 511 includes a left synchronous wheel and a right synchronous wheel, and both the left synchronous wheel and the right synchronous wheel are gears. The groove wheel 512 includes a left groove wheel and a right groove wheel; when the driving assembly 5 runs on the inclined hanging rail 41, the left synchronous wheel is engaged with the synchronous belt 411 on the inclined left hanging rail, and the right synchronous wheel is engaged with the synchronous belt 411 on the inclined right hanging rail; when the driving assembly 5 runs on the curved hanging rail 42, the left groove wheel is clamped on the vertical rail of the curved inner circle hanging rail, and the right groove wheel is clamped on the vertical rail of the curved outer circle hanging rail.

[0046] It should be noted that the synchronous belt 411 is made of rubber, which can ensure that the synchronous wheel 511 and the rack on the synchronous belt 411 have good bite force while reducing the noise when the synchronous wheel 511 runs on the synchronous belt 411.

[0047] Specifically, the inclined hanging rail 41 is a double-track track, and the corresponding synchronous wheel 511 is also a double-wheel structure, which can travel on the two tracks without slipping; the corresponding curved hanging rail 42 is also a double-track vertical rail track, and the corresponding groove wheel 512 is a double-wheel structure, which can be clamped on the vertical rails of the two tracks. The double-track track is conducive to improving the stability and carrying capacity of the hanging rail elevator car.

[0048] When the driving component 5 runs on the inclined hanging rail 41, the synchronous belt on the inclined left hanging rail meshes with the left synchronous wheel, and the synchronous belt on the inclined right hanging rail meshes with the right synchronous wheel, and the driving component 52 drives the left synchronous wheel and the right synchronous wheel to rotate synchronously, so that the hanging rail elevator car can rise smoothly; when the driving component 5 enters the curved hanging rail 42 area, the left groove wheel is clamped on the curved inner circle hanging rail, and the right groove wheel is clamped on the curved outer circle hanging rail, and the driving component 52 drives the left groove wheel and the right groove wheel to rotate synchronously, so that the hanging rail elevator car can turn smoothly at the curve.

[0049] Furthermore, if Figure 3 As shown, the ends of the curved inner circle hanging rail and the oblique left hanging rail butted against each other, and the ends of the curved outer circle hanging rail and the oblique right hanging rail butted against each other all have parallel overlapping sections. For example, the curved inner circle hanging rail and the curved outer circle hanging rail are both semicircular rails, and their ends extend out a straight section parallel to the oblique left hanging rail and the oblique right hanging rail. When the driving assembly 5 switches the tracks, the synchronous wheel 511 or the groove wheel 512 first smoothly transitions in the straight section, which is beneficial to improving the stability of the operation of the hanging rail elevator car.

[0050] In one embodiment of the present invention, the drive assembly 5 also includes a transmission shaft 53, the transmission shaft 53 is connected to the drive member 52, the left synchronous wheel and the left groove wheel are connected to one side of the transmission shaft 53, the right synchronous wheel and the right groove wheel are connected to the other side of the transmission shaft 53, and the drive member 52 drives the left synchronous wheel, the right synchronous wheel, the left groove wheel and the right groove wheel to rotate simultaneously through the transmission shaft 53.

[0051] It should be noted that the synchronous wheel 511 and the groove wheel 512 on the same side are connected to the transmission shaft 53 and fit together. The groove wheel 512 is located on the side close to the driving member 52, and the diameter of the groove wheel 512 is larger than the diameter of the synchronous wheel 511, forming a large and small wheel similar to a train wheel. The distance between the sides of the groove wheels 512 on both sides that are away from each other is less than or equal to the distance between the two inclined hanging rails 41. Therefore, when the synchronous wheel 511 is running, the groove wheels 512 on both sides can limit the longitudinal sliding of the synchronous wheel 511 on the track to prevent the synchronous wheel 511 from derailing.

[0052] Furthermore, the diameters of the left synchronous wheel and the right synchronous wheel are the same, the diameter of the left groove wheel is smaller than that of the right groove wheel, and the diameter of the curved outer circular track is larger than that of the curved inner circular track. This allows the suspended rail elevator car to maintain horizontal stability when turning at a constant speed, avoid tilting due to track changes, and ensure the safety and comfort of passengers.

[0053] There are multiple groups of elevator frames 6 connected in series, and each group of elevator frames 6 is connected to the hanging rail 4 through a connecting frame 54 and a driving wheel 51.

[0054] Among them, the left synchronous wheel, the left groove wheel, the right synchronous wheel, the right groove wheel, the driving member 52, the transmission shaft 53, and the connecting frame 54 constitute a single-axis four-wheel elevator car to drive the elevator frame 6 to run along the inclined hanging rail 41 and the curved hanging rail 42. During the operation, the left synchronous wheel, the right synchronous wheel, the left groove wheel and the right groove wheel rotate at the same time, and the rotation speed on the inclined hanging rail 41 and the curved hanging rail 42 is kept consistent, ensuring that the hanging rail elevator car can automatically and smoothly turn.

[0055] It should be noted that there are multiple sets of elevator frames 6 connected in series behind the single-axle four-wheel elevator car. Each set of elevator frames 6 located behind the single-axle four-wheel car is connected to the hanging rail 4 through a connecting frame 54, and a transmission shaft 53 and a driving wheel 51 are installed on the connecting frame 54. It is not necessary to install a driving member 52, and the drive of the single-axle four-wheel elevator car drives multiple sets of elevator frames 6 to run synchronously. Of course, in actual use, the number and configuration of the elevator frames 6 can be adjusted according to specific needs.

[0056] Furthermore, two adjacent elevator frames 6 can be connected by a movable shaft, and the movable shaft has movable space in the vertical direction. When multiple groups of elevator frames 6 run to the turning point, the elevator frame 6 on the front side enters the inclined hanging rail 41 area, and the elevator frame 6 on the rear side is still in the curved hanging rail 42 area. At this time, the movable shaft slides up and down without driving the elevator frame 6 on the rear side to rise, thereby preventing the elevator frame 6 on the rear side from leaving the track.

[0057] At the same time, limiters are installed at the beginning of the track of the entrance door platform and the end of the track of the top platform. The limiters can effectively prevent the elevator car from exceeding the track range and ensure safe operation.

[0058] In an embodiment of the present invention, Figure 1 , Fig. 9 As shown, the elevator car frame 6 includes a car body 61, a flip pedal 62, a flip seat 63 and a rotating handle 64. The top of the car body 61 is connected to the connecting frame 54, and the side of the car body 61 close to the connecting frame 54 is bent in a direction away from the stair handrail; the flip pedal 62 is rotatably connected to the lower end of the car body 61; the flip seat 63 is rotatably connected to the car body 61 and is located above the flip pedal 62; the rotating handle 64 is rotatably connected to the car body 61 and is located above the flip seat 63.

[0059] Exemplarily, the car body 61 is composed of two columns and a plate fixed between the columns. The top end of the column is bent or the column is in an L-shaped structure, so that the connection between the top end of the column and the connecting frame 54 is located in the center of the stairwell, and the lower end of the column can be closer to the stair handrail, which is beneficial to increase the standing space for passengers and reduce the lateral space occupied by the elevator frame 6 on the stairs, avoiding interference with the normal passage of the pedestrian stairwell.

[0060] At the same time, the flip pedal 62 is rotatably connected to the lower end of the vehicle body 61. When riding is required, the flip pedal 62 can be unfolded into a horizontal state, which is convenient for passengers to stand or place items; the flip seat 63 is also rotated to a horizontal position for passengers to sit. A seat belt can be provided on the flip seat 63 to ensure the safety of the passengers; the passengers can hold the rotating handle 64 during the ride to ensure safety.

[0061] Furthermore, a control switch for controlling the start and stop of the drive member 52 can be provided on the rotating handle 64, so that passengers can adjust the running state of the elevator car at any time during the ride. When the passenger presses the control switch, the hanging rail elevator car starts to run. When the control switch is released, the hanging rail elevator car stops running, which is beneficial to ensure the safety of the passengers.

[0062] It is understandable that when the rail elevator car is not in operation, the flip pedal 62, the flip seat 63 and the rotating handle 64 are all folded toward the car body 61 to facilitate normal passage through the walking stairwell.

[0063] In one embodiment of the present invention, a sway-proof frame 7 is provided on the side of the vehicle body 61 facing the stair handrail, and the sway-proof frame 7 includes a mounting frame 71 and a half-groove wheel 72. The mounting frame 71 is slidably connected to the vehicle body 61; the half-groove wheel 72 is rotatably connected to the mounting frame 71, and at least two of them are provided, respectively located on both sides of the stair handrail.

[0064] Exemplarily, the mounting frame 71 is used to mount the half-grooved wheel 72. The mounting frame 71 is slidably connected to the vehicle body 61. The mounting frame 71 can move vertically along the vehicle body 61 so as to adjust the position of the half-grooved wheel 72 according to the height change of the stair handrail. A half-grooved wheel 72 is arranged on the side of the stair handrail away from the vehicle body 61, and two half-grooved wheels 72 are arranged on the other side. The mounting frame 71 and the vehicle body 61 have two connection points to ensure the stability of the half-grooved wheel 72. There is a gap between the half-grooved wheels 72 on both sides and the stair handrail, so that the elevator frame 6 can move within a small range, which can effectively prevent the elevator frame 6 from shaking and improve the stability of the overall structure.

[0065] In addition, since the shapes of the stair handrails are different, in order to prevent the anti-sway frame 7 from restricting the normal operation of the hanging rail elevator car at the turning point of the stair handrail, only one half-groove wheel 72 can be provided, and the half-groove wheel 72 is located on the inner side of the stair handrail, and the half-groove wheel 72 can slide along the mounting frame 71, thereby effectively preventing the elevator car frame 6 from shaking. Of course, during actual installation, for different stair handrails, a limiting track can also be installed along the stair handrail, and the half-groove wheel 72 can slide in the limiting track, thereby preventing the elevator car from shaking and preventing the anti-sway frame 7 from restricting the normal operation of the hanging rail elevator car.

[0066] In one embodiment of the present invention, the suspended rail elevator car further includes a control assembly. The control assembly includes a control system and an elevator call panel provided in each floor of the walking stairwell. Exemplarily, the control system is connected to the elevator call panel via a wireless signal, and passengers can call the elevator via the elevator call panel.

[0067] Meanwhile, a wired or wireless method can be selected according to the type of the driving member 52. For example, when the driving member 52 is a wired motor, the power supply system is set on the first floor, and when the hanging rail elevator car goes up, it can take the wires with it along the gap in the middle of the stairwell, and when the elevator car goes down, the power wires fall freely on the vertebral barrel by their own weight and coil around the vertebral barrel by themselves, or can be wound up by a torsion spring take-up wheel.

[0068] The above inventions are only several specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
