Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of installing elevators in walking staircases, and in particular to a straight-rail inclined automatic steering overhead rail elevator car. BACKGROUND

[0002] There are a large number of old communities without installed elevators, which causes inconvenience and safety risks for the elderly or people with limited mobility when going up and down the stairs. Installing elevators is costly, and the structure of old communities cannot fully meet the conditions required for installing elevators. Installing outdoor elevator shafts or corridors is even more costly and affects lighting, later operation and maintenance costs, and many other problems. Therefore, elevators can be installed in walking staircases.

[0003] In existing schemes for installing elevators in walking staircases, some are installed on the stair railings, and the elevators run along the stair railings. Using the technical scheme of installing elevators on stair railings can cause insufficient support of the elevators, resulting in safety and inconvenience problems. Some are installed on the walls of each floor of the staircase. This technical scheme is costly, and some technical schemes cannot be continuously operated, making it difficult to reach in one step. Some technical schemes have the problem of inconvenient steering, and also occupy a large amount of original walking space of the walking staircase. SUMMARY

[0004] To solve the above technical problems, the present application provides a straight-rail inclined automatic steering overhead rail elevator car.

Furthermore, the staggered arrangement of the inclined and curved rails at their connection points allows the suspended elevator car to automatically and smoothly turn, enabling one-stop elevator access for going up or down stairs. Additionally, the inclined rail hanger and curved rail hanger are installed under the inclined treads and rest platform respectively, with the elevator car frame located on one side of the stairwell, thus not occupying a large space in the stairwell.

[0042] The following detailed description of a specific embodiment of the present invention is provided in conjunction with the accompanying drawings. However, it should be understood that the scope of protection of the present invention is not limited to the specific embodiment.

[0043] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the technical solution of this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0044] Many older residential communities lack elevators, causing inconvenience and safety risks for the elderly and those with mobility issues. Adding elevators is costly, and the building structures in older communities often don't fully meet the requirements. Adding outdoor elevator shafts or walkways is even more expensive and presents challenges such as reduced natural light, higher operating costs, and maintenance expenses. Therefore, installing elevators in stairwells is a viable alternative.

[0045] Among the existing solutions for installing elevators in stairwells, some are installed on the stair railings, with the elevator running along the railings. This approach can lead to insufficient elevator support, resulting in safety and inconvenience issues. Other solutions involve installing elevators on the walls of each stairwell. This approach is costly, and some solutions cannot operate continuously, making it difficult to reach destinations in one stop. Some solutions also present problems with turning, and they occupy a significant amount of the original stairwell space.

[0046] Therefore, this invention provides a straight-rail inclined automatic steering suspended rail elevator car, which can carry people or goods, making it convenient to go up and down stairs. During operation, the elevator car can automatically and smoothly turn without occupying a large space in the stairwell.

[0047] At least one embodiment of the present invention provides a straight-rail inclined automatic steering suspended rail elevator car, which is installed in a stairwell. The stairwell includes inclined treads of a rest platform. The suspended rail elevator car includes a hanger, a rail, a drive assembly, and an elevator car frame.

[0048] The hangers include inclined rail hangers and curved rail hangers. The inclined rail hangers are fixedly installed at the bottom of the inclined step plate, and the curved rail hangers are fixedly installed at the bottom of the rest platform plate. The curved rail hangers connect two adjacent inclined rail hangers.

[0049] The suspension rails include inclined suspension rails and curved suspension rails. The inclined suspension rails are connected to the inclined rail hangers, and the curved suspension rails are connected to the curved rail hangers. The curved suspension rails connect two adjacent inclined suspension rails, and the ends of the inclined suspension rails and curved suspension rails are staggered.

[0050] The drive assembly includes a drive wheel, a drive component, and a connecting frame. The drive wheel slides on an inclined or curved suspension rail. The drive component is used to drive the drive wheel to travel along the inclined or curved suspension rail. The drive component is connected to the connecting frame. The drive wheel includes a synchronous pulley and a grooved pulley. When the drive assembly is located under the inclined step plate, the synchronous pulley travels on the inclined suspension rail. When the drive assembly is located under the rest platform plate, the grooved pulley travels on the curved suspension rail.

[0051] An elevator car frame, connected to a connecting frame, is located on the side of the stairwell near the stair handrail and is used to carry people or goods.

[0052] In the straight-rail inclined automatic steering suspended rail elevator car provided in the above embodiments of the present invention, people or goods can be carried by the elevator car frame. Driven by the drive component, the elevator car frame travels along the inclined suspension rail and the curved suspension rail, which facilitates going up and down the stairs. The inclined suspension rail and the curved suspension rail are staggered at the connection point, so that the suspended rail elevator car can automatically and smoothly turn. The inclined rail bracket and the curved rail bracket are respectively installed under the inclined step plate and under the rest platform. The elevator car frame is located on one side of the stairwell, so it does not occupy a large space in the stairwell.

[0053] The present invention will be described below through several specific embodiments. To keep the following description of the embodiments clear and concise, detailed descriptions of known functions and components may be omitted. When any component of an embodiment of the present invention appears in more than one drawing, the component may be represented by the same reference numerals in each drawing.

[0054] like Figure 1 , Figure 2 , Figure 4 , Figure 5 As shown, this embodiment of the invention provides a straight-rail inclined automatic steering suspended rail elevator car. The suspended rail elevator car is installed in a stairwell, which includes inclined treads 1 of a rest platform. The suspended rail elevator car includes a hanger 3, a rail 4, a drive assembly 5, and an elevator car frame 6.

[0055] The hanger 3 includes a sloping rail hanger 31 and a curved rail hanger 32. The sloping rail hanger 31 is fixedly installed at the bottom of the sloping step 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 sloping rail hangers 31.

[0056] The suspension rail 4 includes an inclined suspension rail 41 and a curved suspension rail 42. The inclined suspension rail 41 is connected to the inclined rail hanger 31, and the curved suspension rail 42 is connected to the curved rail hanger 32. The curved suspension rail 42 connects two adjacent inclined suspension rails 41, and the ends of the inclined suspension rail 41 and the curved suspension rail 42 are staggered.

[0057] Drive assembly 5 includes drive wheel 51, drive member 52 and connecting frame 54. Drive wheel 51 slides on inclined rail 41 or curved rail 42. Drive member 52 is used to drive drive wheel 51 to travel along inclined rail 41 or curved rail 42. Drive member 52 is connected to connecting frame 54. Drive wheel 51 includes synchronous wheel 511 and grooved wheel 512. When drive assembly 5 is located under inclined step plate 1, synchronous wheel 511 travels on inclined rail 41. When drive assembly 5 is located under rest platform plate, grooved wheel 512 travels on curved rail 42.

[0058] The elevator frame 6 is connected to the connecting frame 54. The elevator frame 6 is located on the side of the stairwell near the stair handrail and is used to carry people or goods.

[0059] Specifically, when installing the suspended rail elevator car, starting from the first floor, equidistant inclined rail hangers 31 are fixed to the bottom surface of the inclined treads 1 of each stairwell, and equidistant curved rail hangers 32 are fixed to the bottom surface of the rest platform slabs of each stairwell. The inclined rail hangers 31 and curved rail hangers 32 serve as the lifting structure for the suspended rail elevator car. They can be anchored within the cast-in-place concrete treads at the top of the stairwell, and the multiple anchor points, with their intervals, will not damage the building's load-bearing structure. This achieves stable lifting of the entire suspended rail elevator car and also helps reduce the space occupied in the stairwell. For example, the inclined rail hanger 31 includes anchor rods and a fixing frame. The anchor rods are connected to the cast-in-place concrete treads of the stairwell via expansion bolts, and the fixing frame is connected to the anchor rods via bolts, ensuring the stability of the hanger 3 and allowing for height adjustment. The curved rail hanger 32 has a similar structure, ensuring the structural safety of the elevator car.

[0060] The suspension rail 4 is connected to the hanger 3. The suspension rail 4 includes an inclined suspension rail 41 and a curved suspension rail 42. The inclined suspension rail 41 is laid on the straight hook of the inclined rail hanger 31, which is fixed to the bottom surface of the inclined step plate 1. The curved suspension rail 42 is connected to the curved rail hanger 32, which is fixed to the bottom surface of the rest platform plate. The curved suspension rail 42 has a semi-circular or arc-shaped design to ensure that the elevator car turns smoothly and at a constant speed at turns. The inclined suspension rail 41 is a straight upward track. The connection between the inclined suspension rail 41 and the curved suspension rail 42 adopts a staggered design, which allows the suspended elevator car to turn at a constant speed, thereby improving the operating efficiency and stability of the suspended elevator car at turns.

[0061] The drive assembly 5 is capable of moving along the inclined rail 41 or the curved rail 42. The drive wheel 51 is used to travel on the inclined rail 41 or the curved rail 42, and the drive member 52 is capable of providing power to the drive wheel 51 so that the drive wheel 51 can travel on the inclined rail 41 or the curved rail 42. The connecting frame 54 serves as a mounting platform for the drive wheel 51 and the drive member 52.

[0062] Furthermore, such as Figure 4 , Figure 5 , Figure 6As shown, the drive wheel 51 includes a synchronous pulley 511 and a grooved pulley 512. Both the synchronous pulley 511 and the grooved pulley 512 are connected to the power output end of the drive component 52. When the drive component 5 is located under the inclined step plate 1, the synchronous pulley 511 runs on the inclined suspension rail 41, and the grooved pulley 512 is suspended. When the drive component 5 is located under the rest platform plate, the grooved pulley 512 runs on the curved suspension rail 42, and the synchronous pulley 511 is suspended. At the same time, the connection between the inclined suspension rail 41 and the curved suspension rail 42 is staggered, so that the drive wheel 51 can smoothly transition when switching between different rails.

[0063] It should be noted that the drive component 52 can be a motor, which typically has one output shaft. After the motor is installed in the connecting bracket 54, the overall shape is "7". In this invention, the motor is modified so that both ends of the motor have output shafts, and the output shafts on both sides rotate simultaneously. After the motor is installed in the connecting bracket 54, the drive assembly 5 is T-shaped, and the motor has a built-in power-off braking function.

[0064] The elevator frame 6 is connected to the connecting frame 54. When the drive component 5 moves along the inclined suspension rail 41 or the curved suspension rail 42, it drives the elevator frame 6 to move synchronously, thereby safely and efficiently transporting passengers or goods to different floors. At the same time, the elevator frame 6 is located on the side of the stairwell near the stair handrail, which not only facilitates residents going up and down the stairs and ensures safety, but also improves the utilization rate of the building space.

[0065] The inclined rail hanger 31 is installed at the bottom center of the inclined tread 1, and the curved rail hanger 32 is installed on the landing platform near the stair handrail. Thus, the inclined rail 41 is directly below the inclined rail hanger 31, and the curved rail 42 is directly below the curved rail hanger 32. The drive assembly 5 runs directly below either the inclined rail 41 or the curved rail 42. This design improves the anchoring effect of the inclined rail 41 and reduces the space occupied by the elevator frame 6 at turns, avoiding interference with normal passage and the opening and closing of residents' entrance doors.

[0066] The elevator car 6 carries people or goods. Driven by the drive component 5, the elevator car 6 runs along the inclined suspension rail 41 and the curved suspension rail 42, which facilitates going up and down the stairs. The inclined suspension rail 41 and the curved suspension rail 42 are staggered at the connection point, so that the elevator car can automatically and smoothly turn. The inclined rail bracket 31 and the curved rail bracket 32 ​​are respectively installed under the inclined step plate 1 and the rest platform plate 2. The elevator car 6 is located on one side of the stairwell, so it does not occupy a large space in the stairwell.

[0067] In embodiments of the present invention, such as Figure 3 , Figure 4 , Figure 5 , Figure 6As shown, the inclined suspension rail 41 includes a symmetrically arranged inclined left suspension rail and an inclined right suspension rail. Both the inclined left and right suspension rails are equipped with a synchronous belt 411, which has a rack. The curved suspension rail 42 includes an inner curved suspension rail and an outer curved suspension rail. The inner curved suspension rail is connected to the end of the inclined left suspension rail and is staggered, while the outer curved suspension rail is connected to the end of the inclined right suspension rail and is staggered. The two curved rails are located inside the two inclined rails.

[0068] Synchronizing pulley 511 includes a left synchronous pulley and a right synchronous pulley, both of which are gears. Grooved pulley 512 includes a left grooved pulley and a right grooved pulley; when the drive assembly 5 runs on the inclined suspension rail 41, the left synchronous pulley meshes with the synchronous belt 411 on the inclined left suspension rail, and the right synchronous pulley meshes with the synchronous belt 411 on the inclined right suspension rail; when the drive assembly 5 runs on the curved suspension rail 42, the left grooved pulley is engaged on the vertical rail of the curved inner circular suspension rail, and the right grooved pulley is engaged on the vertical rail of the curved outer circular suspension rail.

[0069] It should be noted that the timing belt 411 is made of rubber, which can ensure that the timing pulley 511 and the rack on the timing belt 411 have good meshing force, while also reducing the noise when the timing pulley 511 runs on the timing belt 411.

[0070] Specifically, the inclined suspension rail 41 is a double-rail track, and the corresponding synchronous wheel 511 is also a double-wheel structure, enabling it to travel on both tracks without slipping; the corresponding curved suspension rail 42 is also a double-rail vertical track, and the corresponding grooved wheel 512 is a double-wheel structure, capable of being respectively engaged on the vertical rails of the two tracks. The double-rail track helps to improve the stability and load-bearing capacity of the suspended elevator car.

[0071] When the drive assembly 5 runs on the inclined suspension rail 41, the synchronous belt on the inclined left suspension rail meshes with the left synchronous pulley, and the synchronous belt on the inclined right suspension rail meshes with the right synchronous pulley. The drive unit 52 drives the left and right synchronous pulleys to rotate synchronously, so as to realize the smooth rise of the suspension rail elevator car. When the drive assembly 5 enters the curved suspension rail 42 area, the left groove wheel is locked in the inner circular suspension rail of the curve, and the right groove wheel is locked in the outer circular suspension rail of the curve. The drive unit 52 drives the left and right groove wheels to rotate synchronously, so as to realize the smooth turning of the suspension rail elevator car at the curve.

[0072] Furthermore, such as Figure 3 As shown, the ends where the inner curved circular rail connects to the left inclined rail and the ends where the outer curved circular rail connects to the right inclined rail both have parallel overlapping sections. For example, both the inner and outer curved circular rails are semi-circular tracks, with their ends extending into a straight section parallel to the left and right inclined rails. When the drive assembly 5 switches tracks, the synchronous pulley 511 or the grooved pulley 512 first smoothly transitions on the straight section, which helps improve the smoothness of the operation of the suspended rail elevator car.

[0073] In one embodiment of the present invention, the drive assembly 5 further includes a drive shaft 53, which is connected to the drive member 52. The left synchronous pulley and the left grooved pulley are connected to one side of the drive shaft 53, and the right synchronous pulley and the right grooved pulley are connected to the other side of the drive shaft 53. The drive member 52 drives the left synchronous pulley, the right synchronous pulley, the left grooved pulley and the right grooved pulley to rotate simultaneously through the drive shaft 53.

[0074] It should be noted that the synchronous pulley 511 and the grooved pulley 512 on the same side are both connected to and fit on the drive shaft 53. The grooved pulley 512 is located on the side closer to the drive member 52, and the diameter of the grooved pulley 512 is larger than the diameter of the synchronous pulley 511, forming a large and small wheel similar to a train wheel. The distance between the two opposite sides of the grooved pulleys 512 is less than or equal to the distance between the two inclined rails 41. Therefore, when the synchronous pulley 511 is running, the grooved pulleys 512 on both sides can limit the synchronous pulley 511 from sliding longitudinally on the track and prevent the synchronous pulley 511 from derailing.

[0075] Furthermore, the left and right synchronous pulleys have the same diameter, the left grooved pulley has a smaller diameter than the right grooved pulley, and the outer diameter of the curved track is larger than the inner diameter of the curved track. This ensures that the suspended elevator car maintains horizontal stability when moving and turning at a constant speed, preventing tilting due to track changes and ensuring passenger safety and comfort.

[0076] Multiple elevator car frames 6 are connected in series, and each elevator car frame 6 is connected to the hanging rail 4 through a connecting frame 54 and a drive wheel 51.

[0077] The single-axle four-wheel elevator car consists of a left synchronous wheel, a left groove wheel, a right synchronous wheel, a right groove wheel, a drive component 52, a transmission shaft 53, and a connecting frame 54. This structure drives the elevator car frame 6 to run along the inclined suspension rail 41 and the curved suspension rail 42. During operation, the left synchronous wheel, the right synchronous wheel, the left groove wheel, and the right groove wheel rotate simultaneously, maintaining the same rotational speed on the inclined suspension rail 41 and the curved suspension rail 42. This ensures that the elevator car can automatically and smoothly navigate curves.

[0078] It should be noted that multiple elevator car frames 6 are connected in series at the rear of the single-axle four-wheel elevator car. Each elevator car frame 6 located at the rear of the single-axle four-wheel elevator car is connected to the hanging rail 4 via a connecting frame 54. The connecting frame 54 is equipped with a drive shaft 53 and a drive wheel 51, eliminating the need for a drive component 52. The single-axle four-wheel elevator car drives multiple elevator car frames 6 to operate synchronously. Of course, in actual use, the number and configuration of elevator car frames 6 can be adjusted according to specific needs.

[0079] Furthermore, two adjacent elevator frames 6 can be connected by a movable shaft, which has vertical movement space. When multiple elevator frames 6 run to a turn, the elevator frame 6 on the front side enters the inclined suspension rail 41 area, while the elevator frame 6 on the rear side remains in the curved suspension rail 42 area. At this time, the movable shaft slides up and down without causing the elevator frame 6 on the rear side to rise, thus preventing the elevator frame 6 on the rear side from derailing from the track.

[0080] Meanwhile, limit switches are installed at the beginning of the track on the entrance door platform and the end of the track on the top floor platform. These limit switches effectively prevent the elevator car from exceeding the track range, ensuring safe operation.

[0081] In embodiments of the present invention, such as Figure 1 , Figure 9 As shown, the elevator frame 6 includes a body 61, a tilting step 62, a tilting seat 63, and a rotating handle 64. The top of the body 61 is connected to a connecting frame 54, and the side of the body 61 closest to the connecting frame 54 bends away from the stair railing. The tilting step 62 is rotatably connected to the lower end of the body 61. The tilting seat 63 is rotatably connected to the body 61 and located above the tilting step 62. The rotating handle 64 is rotatably connected to the body 61 and located above the tilting seat 63.

[0082] For example, the vehicle body 61 consists of two columns and a plate fixed between the columns. The top of the columns is bent or the columns are L-shaped, so that the connection between the top of the column and the connecting frame 54 is located in the center of the stairwell. The lower end of the column can be closer to the stair handrail, which not only increases the standing space for passengers, but also reduces the occupancy of the elevator frame 6 on the horizontal space of the stairwell, and avoids interfering with the normal passage of pedestrian stairwell.

[0083] Meanwhile, the flip-up pedal 62 is rotatably connected to the lower end of the vehicle body 61. When it is necessary to ride, the flip-up pedal 62 can be unfolded into a horizontal state, which is convenient for passengers to stand up or place items. The flip-up seat 63 is also rotated to a horizontal position for passengers to sit on. A seat belt can be installed on the flip-up seat 63 to ensure passenger safety. Passengers can hold the rotating handle 64 during the ride to ensure safety.

[0084] Furthermore, a control switch for controlling the start and stop of the drive unit 52 can be provided on the rotary handle 64, which allows passengers to adjust the operating status of the elevator car at any time during the ride. When a passenger presses the control switch, the suspended elevator car starts to run, and when the passenger releases the control switch, the suspended elevator car stops running, which helps to ensure passenger safety.

[0085] Understandably, when the suspended elevator car is not in operation, the flip-up step 62, flip-up seat 63, and rotating handle 64 are all folded towards the car body 61 to facilitate normal passage in the stairwell.

[0086] In one embodiment of the present invention, an anti-sway frame 7 is provided on the side of the vehicle body 61 facing the stair handrail. The anti-sway frame 7 includes a mounting frame 71 and a semi-grooved wheel 72. The mounting frame 71 is slidably connected to the vehicle body 61; the semi-grooved wheel 72 is rotatably connected to the mounting frame 71, and at least two are provided, located on both sides of the stair handrail respectively.

[0087] For example, mounting bracket 71 is used to mount semi-grooved wheels 72. Mounting bracket 71 is slidably connected to vehicle body 61 and can move vertically along vehicle body 61 to adjust the position of semi-grooved wheels 72 according to changes in the height of the stair handrail. One semi-grooved wheel 72 is provided on the side of the stair handrail away from vehicle body 61, and two semi-grooved wheels 72 are provided on the other side. Mounting bracket 71 has two connection points with vehicle body 61 to ensure the stability of the semi-grooved wheels 72. There is a gap between the semi-grooved wheels 72 on both sides and the stair handrail, allowing the elevator frame 6 to move within a small range, effectively preventing the elevator frame 6 from swaying and improving the overall structural stability.

[0088] Furthermore, since stair handrails vary in shape, to prevent the anti-sway bracket 7 from restricting the normal operation of the suspended elevator car at stair handrail bends, only one semi-grooved wheel 72 may be installed. The semi-grooved wheel 72 is located inside the stair handrail and can slide along the mounting frame 71, effectively preventing the elevator car frame 6 from swaying. Of course, in actual installation, for different stair handrails, a limiting rail can also be installed along the stair handrail. The semi-grooved wheel 72 can slide within the limiting rail, thus preventing the elevator car from swaying and preventing the anti-sway bracket 7 from restricting the normal operation of the suspended elevator car.

[0089] In one embodiment of the invention, the suspended elevator car further includes a control component. The control component includes a control system and a call panel located on each floor's stairwell. Exemplarily, the control system is connected to the call panel wirelessly, allowing passengers to call the elevator via the call panel.

[0090] Meanwhile, depending on the type of drive unit 52, a wired or wireless method can be selected. For example, when the drive unit 52 is a wired motor, the power supply system is set on the first floor. When the suspended elevator car goes up, it can carry the power cord up along the gap in the middle of the stairwell. When the elevator car goes down, the power cord falls freely under its own weight to the cone and coils around the cone itself, or a torsion spring winding wheel can be used for winding.

[0091] The above inventions are merely a few specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
