Description

Technical Field

[0001] The present invention relates to the technical field of elevators, in particular to a suspended rail type electric escalator. Background Art

[0002] At present, with the accelerated arrival of population aging, installing elevators in old residential areas has become a livelihood project advocated by the state and urgently needed by the people. At present, there are mainly three ways to install elevators in old residential areas: one is the traditional vertical lift elevator; the second is to install a straight-track escalator based on the stair surface; the third is a rotary escalator installed on the handrail of the stairs. These three types of elevators can, to a certain extent, solve the current problem of high-rise residents in old residential areas going up and down the stairs due to the lack of elevators. However, due to their inherent characteristics, there are various contradictions and disadvantages in the process of installing elevators in old residential areas, and promotion is difficult. The specific analysis is as follows:

[0003] 1. Analysis of the shortcomings and contradictions of traditional vertical lifts in the renovation of old residential areas:

[0004] This type of elevator is to install an elevator shaft on the facade of an old residential area, transform the original corridor ventilation windows of the residential area into the entrance door of the elevator, and connect the elevator shaft with the flat staircase of the old residential area by building a corridor. The elevator car realizes vertical up and down movement in the elevator shaft, and lifts the user vertically to the target floor to solve the problem of going up and down the stairs. The elevator is composed of a traction system, a safety system, a counterweight balancing device, a control system, a car and other parts. Its main principle is to use a drag motor to pull the car to move vertically up or down, so as to achieve the purpose of transporting passengers to a specific floor. Because this type of elevator has the advantages of mature technology, safety and reliability, beautiful appearance, large carrying capacity, high operating efficiency, simple and convenient operation, it has become the main way to install elevators in old residential areas. However, during the specific implementation of the renovation of old residential areas, the following problems were found:

[0005] First, the project is expensive. Currently, the cost of installing a six-story elevator typically ranges from 400,000 to 600,000 yuan. Even with a 50% government subsidy in some areas, the cost of over 200,000 yuan shared by homeowners is still a significant expense, and even if spread evenly across each household, it still represents a significant cost. This, to a certain extent, limits the appeal of installing elevators in older residential communities.

[0006] The second issue is the long construction period. After the owner reaches an installation agreement, the elevator construction party needs to survey the construction site and design and produce construction drawings. Only after completion can the actual construction phase begin. During the construction process, the elevator shaft is built in a layer-by-layer manner. That is, after the frame of the first floor is completed, the frame of the second floor can be constructed. Construction cannot be carried out on multiple floors at the same time, which to a certain extent limits the efficiency of the operation. Therefore, the current installation of a vertical lift operation generally takes more than one month. The excessively long construction period has, to a certain extent, affected the normal life of the owner.

[0007] Third, the extent of the transformation is large. Since the old residential areas originally did not have elevator shafts, during the installation of elevators, the original corridor ventilation windows need to be converted into doorways for elevator entrances. At the same time, accessories such as elevator corridors need to be installed. This has changed the original floor structure to a certain extent, and has had a certain impact on the lighting, fire protection and other aspects of the old residential areas. At the same time, the elevator shaft on the exterior wall will have a certain impact on the stress on the wall when it is exposed to severe weather such as typhoons, and there are safety hazards to a certain extent. When installing vertical lift elevators in old residential areas, the elevator shaft will change the original sewage pipe system of the community. Generally, the original straight sewage pipe is transitioned through 4 90-degree bends, which will increase the risk of blockage of the sewage pipe in the old residential area to a certain extent. The existence of these disadvantages has, to a certain extent, suppressed the demand for installing elevators in old residential areas.

[0008] Fourth, it cannot reach the same floor. Currently, the installation of vertical lifts is generally done by converting the staircase ventilation windows into doorways. The elevator usually arrives at the transition floor in the middle of the floor, that is, the middle floor, rather than directly entering the residents' level position. After taking the elevator to the station, passengers still need to walk half a floor to enter their homes, which to some extent reduces the passenger experience of the elevator.

[0009] 2. Analysis of the shortcomings and contradictions of installing straight-track escalators based on stair surfaces in the renovation of old residential areas:

[0010] This type of elevator is a new type of elevator that has emerged in recent years. It features an elevator track fixed to the staircase against the wall and consists of a transmission mechanism, folding pedals, and transmission gears. A rack is mounted on the track, and the gears mounted on the transmission mechanism, driven by a drive motor, cooperate with the rack to achieve upstairs and downstairs travel, resolving the inconvenience faced by the elderly. This elevator has the advantages of low construction cost, convenient and efficient installation, short construction period, and minimal modification, and has considerable application value. However, in actual use, it suffers from the following deficiencies:

[0011] First, the elevator has a low capacity. Because the track is installed on the wall-facing side of the staircase, there's a certain offset between the pedals and the track. The passenger's center of gravity isn't located in the center of the track, resulting in uneven force on the track. As a result, the elevator can only carry one passenger up and down the stairs at a time, which, to a certain extent, limits its promotion and use.

[0012] Second, it lacks direct access to floors. Because the elevator can't turn, passengers need to switch to another step after reaching a floor. Consequently, reaching the desired floor requires multiple transfers, resulting in low efficiency and, to a certain extent, limiting its widespread adoption.

[0013] Third, it takes up corridor space. The tracks of this type of elevator are laid directly on the stair steps, generally about 20 centimeters away from the wall, which will take up a certain amount of corridor space. Pedestrians walking in the corridor are prone to falling due to stepping on the tracks, which poses a certain safety hazard.

[0014] 3. Analysis of the shortcomings and contradictions of the rotary escalator installed in the stair handrail in the renovation of old residential areas:

[0015] This elevator is a new type of elevator that installs the track at the stair handrail position. It effectively solves the problem of straight track elevators installed on the stair surface that require continuous transfers and cannot reach the destination directly. It has the advantages of low cost and short installation period, and has certain competitiveness. However, it has also been found to have certain problems during actual use. Specifically, there are the following deficiencies:

[0016] First, insufficient carrying capacity. This elevator is side-mounted on the stair handrail, requiring passengers to stand or sit on the corresponding seats to ascend and descend. Because the track is subjected to lateral forces, the load-bearing capacity is low, making it incapable of transporting a large number of passengers up and down stairs. Furthermore, the elevator's small turning radius and slow, unsmooth turning speed increase passenger discomfort, somewhat impacting the overall ride experience.

[0017] Second, operating efficiency is low. Due to the relatively small turning radius of this elevator, deceleration is necessary to enhance safety and improve comfort. Therefore, the relatively low operating speed limits the large-scale deployment of this elevator to a certain extent, making it suitable only for elderly families and unable to meet the needs of medium-sized passenger flows in older residential communities.

[0018] Third, the renovation required a relatively large scale. The elevator's track was a custom-made one, attached to stairs or specially designed supports. Therefore, the renovation required modifying the existing corridor handrails and installing specialized handrails that matched the track, which contributed to a relatively high construction cost.

[0019] The above analysis shows that while the three types of elevators mentioned above can, to a certain extent, address the lack of elevators in older residential communities, their inherent contradictions and shortcomings mean that, despite the urgency of installing elevators in older communities, progress remains slow. Furthermore, post-installation management is also unclear, leading to numerous conflicts. Therefore, there is an urgent need to provide a new type of elevator that is low-cost, safe, efficient, and has a high carrying capacity.

[0020] The Chinese invention patent, patent number: 201810617281.3 discloses a suspended corridor elevator, including an I-beam track device and a monorail train, which are fixedly arranged on the top plate corresponding to the stair ramp section and the top plate corresponding to the stair turning platform; the monorail train includes a series of rail car devices, the rail car device includes a load-bearing bracket, and two sets of load-bearing wheel pairs are symmetrically arranged on the two sides of the upper end of the load-bearing bracket. The load-bearing wheel pairs are respectively clamped in the grooves on the belly of the track device, and the lower edges of the two sets of load-bearing wheel pairs are respectively in contact with the upper end surface of the lower flange of the track device and can roll on the flange; the load-bearing bracket is rotatably provided with a load-bearing hanger, and the other end of the load-bearing hanger is hingedly provided with a passenger pedal; the rail car device is provided with a driving gear, and the driving gear is engaged with a transmission rack in the middle part of the lower end surface of the track device, and the driving motor drives the driving gear to rotate. The patent structure is too simple. Although it solves some existing problems to a certain extent, it cannot effectively solve the difficulties faced by elevator renovation in old communities. There is no specific technical solution for changing straight tracks to curved tracks, and it cannot make the elevator change tracks and run smoothly. No substantial progress or breakthrough has been made in technology. Summary of the Invention

[0021] The purpose of the present invention is to solve the problems existing in the process of installing elevators in existing old communities: the vertical elevator cost is too high, the construction period is long, it cannot reach the same floor, and the process is relatively complicated; the straight-track escalator installed on the stair surface has the following practical problems: the carrying capacity is small, it cannot reach the floors directly, and it occupies the corridor space; the rotary escalator installed on the stair handrail has insufficient carrying capacity, low operating efficiency, and a relatively large renovation range. The present invention is a suspended-track escalator designed specifically for the renovation of old communities.

[0022] In order to achieve the above-mentioned purpose, a suspended rail type electric escalator is designed: a suspended rail type electric escalator, characterized by comprising:

[0023] A rail sleeper beam, the rail sleeper beam being installed on the back of the stairs;

[0024] Track, the track is connected to the track sleeper through a connector, the track includes a flat semicircular track and a straight track, and racks are installed on the outer side of the flat semicircular track and the straight track;

[0025] A power transmission device is used to connect the escalator car to the track. The power transmission device includes at least a traction motor, a vertically separated drive shaft assembly, and a horizontally separated drive shaft assembly. The output shaft of the traction motor is engaged with the first gear of the vertically separated drive shaft assembly, and the first gear of the vertically separated drive shaft assembly is engaged with the second gear of the horizontally separated drive shaft assembly. The second gear of the horizontally separated drive shaft assembly is used to engage the rack on the straight track, and the first gear of the vertically separated drive shaft assembly is used to engage the rack of the semicircular track.

[0026] Preferably: a track connector protruding outward is provided in the middle of the straight rail, a rack is provided on one side of the track connector, a rack is provided in the middle or lower position of the outer side of the arc surface of the flat semicircular track, the connection between the straight rail and the semicircular track is an overlapping area of ​​the rack teeth, the first gear of the vertical separation drive shaft assembly of the power transmission device in the overlapping area meshes with the rack of the flat semicircular track, and the second gear on the horizontal separation drive shaft assembly meshes with the rack on the straight rail.

[0027] Preferably: the power transmission device also includes a frame structure, a notch is provided at the top of the frame structure for matching the track connector on the straight rail, a horizontally separated transmission shaft assembly is provided on one side of the top of the frame structure, and a positioning track wheel is provided on the other side, the horizontally separated transmission shaft assembly is arranged horizontally and meshed with the vertically separated transmission shaft arranged longitudinally, the first gear of the vertically separated transmission shaft is connected to the transmission shaft, and a bevel gear is provided at the bottom of the transmission shaft, which meshes with one end of the horizontally arranged motor output shaft.

[0028] Preferably: the horizontally separate transmission shaft assembly includes an optical shaft, the optical shaft cooperates with the second bevel gear and the second gear and cannot rotate, the hollow track wheel is sleeved on the outside of the optical shaft, the two sides of the hollow track wheel are fixed to the optical shaft by retaining springs, the hollow track wheel can rotate freely around the optical shaft, when the bevel gear drives the optical shaft, and the optical shaft drives the second gear to rotate, the hollow track wheel and the optical shaft rotate asynchronously; the vertically separate transmission shaft assembly includes a transmission shaft, the transmission shaft cooperates with the first bevel gear and the first gear and cannot rotate, the hollow track wheel is sleeved on the outside of the transmission shaft, the two sides of the hollow track wheel are fixed to the transmission shaft by retaining springs, the hollow track wheel can rotate freely around the transmission shaft, when the bevel gear drives the transmission shaft, and the transmission shaft drives the first gear to rotate, the hollow track wheel and the transmission shaft cannot rotate synchronously.

[0029] Preferably: a universal connecting rod fixing groove is provided on one side of the power transmission device, the universal connecting rod fixing groove cooperates with the sphere of the universal connecting rod, the other end of the universal connecting rod is connected to the universal connecting rod base body, and the universal connecting rod is cooperated with on the other side of the universal connecting rod base body, and the other end of the universal connecting rod is connected to the universal connecting rod fixing groove on the car support seat, so that the power transmission device can drag the car to achieve horizontal turning, and it can move back and forth smoothly when transitioning from a straight track to a horizontally set flat semicircular track, and at the same time realize a single power source to drive multiple cars to rise or fall at the same time.

[0030] Preferably: the car is closely matched with the straight rail or the flat semicircular rail through several positioning track wheels. The car also includes a posture control assembly, which includes a car bearing shaft, a fixed shaft, a self-locking contact, a reset spring, a toggle rod and a cable. The fixed shaft is fixedly installed at the bottom end of the car support seat, and there is a pin groove at one end of the fixed shaft. The pin on the self-locking contact cooperates with the pin key of the fixed shaft so that the self-locking contact can only slide left and right but not rotate and slide. The lower side of the car bearing shaft is connected to the car.

[0031] Preferably: when the car support seat drives the car to move up and down along the straight track through the car bearing shaft, the car, under the action of gravity, drives the car bearing shaft to deflect around the fixed axis. At this time, the contacts on the self-locking contacts will lock with the grooves on the car bearing shaft, locking the car vertically at a fixed angle between the vertical and horizontal planes;

[0032] When the car support seat moves to the intersection of the straight rail and one end of the flat semicircular rail, the car reversing contact installed between the two rails will toggle the toggle rod installed on the car support seat to cause deflection. One end is fixed to the toggle rod, and the other end is fixed to the self-locking contact. The cable will drag the self-locking contact to shift to the right. At this time, the contact on the self-locking contact will disengage from the groove on the car bearing shaft. At this time, the car support seat changes from cooperating with the straight rail to cooperating with the flat semicircular rail. Under the action of its own gravity, the car bearing shaft and the car begin to rotate around the fixed axis installed on the car support seat. When the car rotates again to be perpendicular to the horizontal plane, the toggle rod surpasses the car reversing contact, and the toggle rod returns to its initial state under the action of the return spring. At this time, the self-locking contact slides to the left under the action of the return spring and locks with the other groove of the car bearing shaft. The car bearing shaft stops rotating, completing the second reversing action.

[0033] As the car support seat continues to move, the toggle rod will disengage from the car reversing contact fixed at the intersection of the two tracks. Under the reaction force of the reset spring, the toggle rod returns to its initial position. At this time, the contact on the self-locking contact will cooperate with the new groove on the car bearing shaft, and the car will be locked at the new angle.

[0034] Preferably, the elevator car comprises multiple elevator cars, and universal connecting rod fixing slots are installed on the power transmission device, the elevator car support base, and the universal connecting rod base. The power transmission device, the elevator car support base, and the universal connecting rod base are sequentially connected via universal connecting rods, and are connected to the track with spacing between each of them. This allows for synchronous linkage of multiple elevator cars under a single power source. Simultaneously, when the elevator descends, the power transmission device transmits power to each elevator car sequentially via the universal connecting rods, pushing the elevator car support base to drive the elevator car to descend in the opposite direction on the horizontally arranged flat semicircular track.

[0035] Preferably, the car includes an upper folding joint at the top, the upper folding joint being connected to the middle folding joint via an upper folding column, the middle folding joint being connected to the folding step via a lower folding column, the upper folding column being approximately the same length as the folding step. The folding handrail is perpendicular to the folding column, the folding step is provided with a step hinge on the side, the car is surrounded by front and rear folding fences, an infrared switch is provided at the bottom, and a floor selection button and floor display are provided opposite the folding handrail. The car includes at least the folding step and the folding joint, and the folding step automatically folds when unloaded, driven by a return spring or motor within the folding joint.

[0036] Preferably: when the traction motor generates a forward or reverse rotation torque, the rotation torque is transmitted through the bevel gear and the transmission shaft to transmit power to the vertical separation transmission shaft assembly, the upper bevel gear of the vertical separation transmission shaft assembly is meshed with the bevel gear on the horizontal separation transmission shaft assembly, and the first gear and the second gear installed on the vertical separation transmission shaft assembly and the horizontal separation transmission shaft assembly start to rotate synchronously, when the power transmission device runs on the straight rail, the second gear installed on the horizontal separation transmission shaft assembly is meshed with the rack on the straight rail, and under the push of the traction motor, the elevator is driven to realize upward or downward movement on the straight rail;

[0037] The first gear installed on the vertically separated transmission shaft assembly has no rack on the side of the straight track, resulting in idling. When the power transmission device reaches the position of the flat semicircular track, an overlapping rack is provided at the intersection of the straight track and the flat semicircular track. Therefore, when the power transmission device transitions from the straight track to the flat semicircular track, the first gear and the second gear installed on the vertically separated transmission shaft assembly and the horizontally separated transmission shaft assembly simultaneously cooperate with the rack fixed on the straight track and the flat semicircular track to achieve the transition of the power transmission device from the straight track to the flat semicircular track.

[0038] After the overlapping rack transition is completed, since the leveling semicircular track is only equipped with an arc-shaped rack on the side and no rack is installed on the top, the first gear on the vertically separated transmission shaft assembly cooperates with the arc-shaped rack. At this time, the horizontally separated transmission shaft assembly is supported by the hollow track wheel, and the second gear is idle. At this time, the power transmission device is driven by the first gear on the vertically separated transmission shaft assembly to achieve leveling turning;

[0039] When the power transmission device runs to the connection between the end of the flat semicircular track and the beginning of the straight track, a rack is laid out at the same time to form an overlapping area. After the power transmission device passes through the overlapping area, the first gear on the vertically separated transmission shaft assembly becomes idle, and the driving force is converted into the second gear installed on the horizontally separated transmission shaft assembly to cooperate with the rack on the straight track to drive the elevator up or down. The power transmission device realizes the reversal from the flat semicircular track to the straight track.

[0040] Compared with the prior art, the present invention has the following advantages:

[0041] 1. Compared with traditional car-type vertical lift elevators, it has the following advantages:

[0042] 1. Low cost. First, the elevator itself is low-cost. Due to the unique structural features of this invention, only rails need to be installed on the back of the staircase to achieve the purpose of elevator up and down movement, which reduces manufacturing costs to a certain extent. Second, it has the advantages of simple structure and easy installation. Only rails need to be installed on the back of the staircase, without the need for additional facilities such as elevator shafts or modifications to the existing floor structure, which reduces construction costs to a certain extent.

[0043] 2. Short construction period. The present invention is installed by laying tracks on the back of the stairs. The car, power transmission device and other equipment have been manufactured in the factory. During installation, only the tracks and cable brackets and other equipment need to be installed. The present invention can install tracks on multiple floors at the same time. There is no need to wait until the first floor track is installed before installing the second floor. It is only necessary to locate the size of the tracks on each floor and then close them. After closing, the cables can be laid. This shortens the construction period to a certain extent and improves work efficiency.

[0044] 3. Minimal modification. During installation, the present invention does not require modification of existing ventilation windows, stairs, or other parts, nor does it require the installation of facilities such as elevator shafts or changes to residential sewage pipes. Instead, it only requires the installation of bolsters, rails, and other facilities on the existing stairs, which are fixed to the wall with expansion screws. Furthermore, an elevator electrical control box is installed on the third floor, and up / down selector buttons are installed on each floor. This completes the installation of the elevator with minimal modifications.

[0045] 4. Able to reach all floors. Since this elevator transports passengers up or down by laying tracks, if a residential complex has 6 floors, a straight track extending to the 6.5-story floor and a semi-circular track extending to the 6th floor can be installed on the 6th floor. On the other side of the semi-circular track extending to the roof of the 6th floor, the elevator can reach the 6th floor and achieve the purpose of reaching all floors.

[0046] 2. Compared with the existing straight track pedal type escalator, it has the following advantages:

[0047] First, it can operate continuously. Existing straight-track pedal escalators install a straight track on each staircase, with a running motor installed on the track to enable passengers to go up and down. However, after completing a staircase, passengers must disembark, pass through the leveling floor, and transfer to the second escalator, then continue back and forth until they reach the desired floor. This cumbersome operation procedure is generally unsuitable for installing elevators in older residential areas and is only suitable for homes. The present invention, however, uses a traction motor along pre-laid tracks to achieve direct access to each floor, resolving the drawback of this type of elevator requiring continuous transfers.

[0048] Secondly, it has a large carrying capacity. Firstly, the special track layout of this elevator determines its large carrying capacity. Because the track center of this elevator is located in the middle of the center of gravity of the car, the force is more evenly distributed, which reduces the requirements for the track and increases the carrying capacity. Secondly, this elevator is composed of a traction motor, a universal connecting rod, a car support seat, and other parts. Before the elevator is installed, the number of cars can be flexibly adjusted according to the passenger flow of the community. Four pedals can be parked simultaneously on the same floor. If the number of pedals needs to be increased, the additional pedals can be parked on the upper steps of the floor to meet the needs of large-scale transportation.

[0049] The third is high transportation efficiency. The present invention uses a flat semicircular track to achieve the purpose of reversing, which provides a soft turning experience. There is no need to reduce the speed of the entire elevator due to the small turning radius. In this way, it can achieve the requirements of up and down passengers with a stable running speed and smooth turning experience, thereby improving transportation efficiency.

[0050] 3. Compared with curved track escalators / seat escalators, it has the following advantages:

[0051] First, they offer a large carrying capacity. Curved elevators are a new type of elevator with tracks installed near the stair railing. While they offer the advantage of being able to reach the desired floor directly, their lateral force means they can only carry one passenger at a time, resulting in low efficiency and, to a certain extent, limiting their widespread adoption.

[0052] Second, it is smarter. Since the operating system of this type of elevator is basically the same as that of traditional vertical lifts, when operating it, passengers only need to press the floor selection button in the car to directly reach the target floor, without having to press the up or down switch by themselves throughout the whole process, making the operation simpler.

[0053] At the same time, the elevator also has the following advantages:

[0054] First, it takes up minimal space. The elevator's foldable cabin unfolds when passengers use it and automatically folds after exiting, leaving ample space for people using the stairs. This prevents any disruption to those walking up the stairs during operation. Furthermore, the folded elevator minimizes the impact on freight transport, taking up minimal space on the existing staircases and impacting other residents.

[0055] Second, the noise is low. The track wheels of this elevator are rubber rollers, and the elevator makes less noise during operation, reducing the impact on residents. BRIEF DESCRIPTION OF THE DRAWINGS

[0079] See also Figure 1 、 Figure 2 The basic working principle is that a rail sleeper 74 is installed on the back of the staircase in the corridor of an old residential building, and the track 8 is fixed to the rail sleeper 74. The power transmission device 2, the car support base 3, and the universal connecting rod base 4 are fixed to the track 8 via the positioning track wheel 43, the vertical split drive shaft assembly 47, and the horizontal split drive shaft assembly 48. The car 6 is connected to the car support base 3. The car support base 3, the universal connecting rod base 4, and the power transmission device 2 are connected to each other via the universal connecting rod 7. Driven by the power transmission device 2, the car 6 spirals up or down around the track 8.

[0080] See also Figure 5 、 Figure 6 、 Figure 11 、 Figure 12 、 Figure 13 、 Figure 15 、 Figure 18 and Figure 19 To further illustrate the above principle: a rail sleeper 74 is mounted on the back of a staircase 73. The locking end of the rail sleeper 74 latches with the stair step at a right angle, while the other side is secured to the wall with expansion screws. The rail connector 23 on track 8 is mounted on the rail sleeper 74. Track 8 consists of a flat semicircular track 20 and a straight track 22. The curved rack 21 is mounted on the outer side of the flat semicircular track 20, while the rack 24 is mounted on the straight track 22. The rack teeth overlap at the junction of the straight track 22 and the flat semicircular track 20, with an overlap of approximately 5-7 teeth. Its purpose is: when the second gear 80 on the horizontally separated transmission shaft assembly 48 on the power output device 2 is driven by the traction motor 39 to move up or down along the rack 24 on the straight rail 22, when the power transmission device 2 reaches the end of the straight rail 22 and enters the leveling layer, it automatically turns to the leveling semicircular track 20. The horizontally separated transmission shaft assembly 48 installed on the power transmission device 2 automatically enters the rack 24 on the straight rail 22 under the push of the second gear 80, completing the switching from the leveling semicircular track 20 to the straight rail 22. This coordination method enables the car to achieve turning and switching under the premise of a single row of racks and a single power source. It ensures that the entire elevator is uninterrupted and unstuck during operation, achieves the purpose of smooth lifting and lowering, and improves the comfort of the elevator ride. A universal connecting rod fixing groove 45 is installed on one side of the power output device 2, and the fixing groove 45 cooperates with the ball 56 of the universal connecting rod 7. The other end of the universal connecting rod 7 is connected to the universal connecting rod base body 4. The universal connecting rod 7 cooperates on the other side of the universal connecting rod base body 4, and the other end of the universal connecting rod 7 is connected to the universal connecting rod fixing groove 45 on the car support seat 3. The purpose is to realize that the power output device 2 drags the car 6 to achieve horizontal turning, and it can move back and forth smoothly when transitioning from the straight rail 22 to the horizontal semicircular track 20. A single power source drives multiple cars to rise or fall at the same time, thereby sending passengers to the corresponding floors.

[0081] See also Figure 11 、 Figure 12 and Figure 13When the traction motor 39 generates forward or reverse rotational torque, the torque is transmitted through the bevel gear 46 and the drive shaft 49 to the vertical split drive shaft assembly 47. The upper bevel gear 52 of the vertical split drive shaft assembly 47 meshes with the bevel gear 52 on the horizontal split drive shaft assembly 48. The second gear 80 mounted on the vertical split drive shaft assembly 47 and the horizontal split drive shaft assembly 48 begins to rotate synchronously. When the power transmission device 2 operates on the straight rail 22, the second gear 80 mounted on the horizontal split drive shaft assembly 48 meshes with the rack 24 on the straight rail 22. Driven by the traction motor 39, the elevator is driven to achieve upward or downward movement on the straight rail 22.

[0082] The first gear 54 mounted on the vertically split drive shaft assembly 47 idles because there is no rack on the side of the straight track 22. When the power transmission device 2 reaches the leveling semicircular track 20, there is an overlapping rack with 5-7 teeth at the intersection of the straight track 22 and the leveling semicircular track 20. Therefore, when the power transmission device 2 transitions from the straight track 22 to the leveling semicircular track 20, the first gear 54 mounted on the vertically split drive shaft assembly 47 cooperates with the rack on the leveling semicircular track 20, and the second gear 80 on the horizontally split drive shaft assembly 48 cooperates with the rack on the straight track 22, completing the transition of the power transmission device 2 from the straight track 22 to the leveling semicircular track 20.

[0083] After the 5-7 tooth transition is complete, since the leveling semicircular track 20 is only equipped with an arcuate rack 21 on the side, and no rack is installed on the top, the first gear 54 on the vertical split drive shaft assembly 47 cooperates with the arcuate rack 21. At this time, the horizontal split drive shaft assembly 48 is supported by the hollow track wheel 53, and the second gear 80 is idle. At this time, the power transmission device 2 achieves a leveling turn under the push of the first gear 54 on the vertical split drive shaft assembly 47.

[0084] When the power transmission device 2 reaches the junction between the end of the flat semicircular track 20 and the beginning of the straight track 22, a rack is installed simultaneously, with an overlap area of ​​5-7 teeth. After the power transmission device 2 passes through the overlap area, the first gear 54 on the vertical split drive shaft assembly 47 idles, and the driving force is transferred to the second gear 80 mounted on the horizontal split drive shaft assembly 48, which cooperates with the rack 24 on the straight track 22 to drive the elevator up or down, and the power transmission device 2 achieves a direction change from the flat semicircular track 20 to the straight track 22.

[0085] Figure 12 for Figure 11 An exploded view of the horizontally split drive shaft assembly 48 is shown in FIG. Figure 13 for Figure 11Exploded view of the vertically split drive shaft assembly 47 in FIG. Its function is to provide support for the power transmission device 2 while transmitting the kinetic energy of the traction motor 39 through the optical shaft 49 to the second gear 80. The driven second gear 80 meshes with the arc-shaped rack on the leveling semicircular track 22 and the rack 24 on the straight track 20. As the gears rotate, the car is driven upward or downward. Its working principle is: the optical axis 49 is tightly fitted with the bevel gear 46 and the second gear 80 and cannot rotate. The hollow track wheel 53 is sleeved on the outside of the optical axis 49. The two sides of the hollow track wheel 53 are fixed to the optical axis 49 by the retaining spring 50. The hollow track wheel 53 can rotate freely around the optical axis 49. When the bevel gear drives the optical axis 49 and the optical axis 49 drives the second gear 80 to rotate, the hollow track wheel 53 rotates asynchronously with the optical axis 49. The number of rotations is related to the travel distance between the hollow track wheel 53 and the straight rail 20 or the flat semicircular rail 22. In this way, it is ensured that the rotation of the hollow track shaft 48 is not affected by the power transmission device 2 while it is outputting power, thereby achieving the purpose of synchronously realizing two functions of a single axis.

[0086] See also Figure 7 、 Figure 8 and Figure 9 A cable tray 1 is installed parallel to the wall side of the straight track 22 and the flat semicircular track 20. The cable-laying device 5 on the power transmission unit 2 routes the elevator's command signals and power cables within the cable tray 1 via cable-laying contacts 30. A rotating conductive slip ring 29 on the cable-laying device 5 converts the rotating cable from the cable winch 33 into a static cable for use by power-consuming components such as the floor display and floor selection buttons 10 and the traction motor 39, completing signal communication and transmission. When the power transmission unit 2 pulls the car 6 upward or downward, the cable-laying contacts 30 of the cable-laying device 5 push the lever 27 mounted on the cable tray slot 25 to rotate in the same direction as the power transmission unit 2. After the contacts 30 of the cable-laying device 5 pass the lever 27, the lever 27 returns to its original position under the reaction force of the return spring 26. The already-laid cable is now resting on the lever 27, completing the cable-laying task. If the elevator moves in the reverse direction, the cable laid on the cable bracket 1, the cable contact 30 on the cable-laying device 5 will push the lever 27 in the reverse direction to move in the reverse direction. At this time, the cable is in a loose state, and the toggle switch 31 on the cable-laying device 5 will push the cable under the force of the return spring 34. At this time, the contact 36 on the toggle switch 31 is closed, and the circuit forms a loop, driving the cable-laying motor 32 to move in the forward direction. One end of the cable is fixed on the cable winch 33 and starts to rotate in the forward direction. The loosened cable is tightened on the cable winch 33 in turn; after the cable is tightened, it will press the toggle switch 31 to move in the reverse direction, and the contact 36 on the toggle switch 31 will disengage, the entire circuit is disconnected, and the collection action stops, completing the entire cable-retracting action.

[0087] See also Figure 16 、 Figure 17 and Figure 19 The elevator car 6 is mounted on the car support base 3. Six positioning track wheels 43 are respectively mounted on the car connector 59. The six track wheels closely cooperate with the straight rail 22 and the flat semicircular track 20 to ensure that the car support base 3 does not shake or deflect. The car 6 is connected to the posture control assembly 60 at the bottom end of the car support base 3. A fixed shaft 61 is fixedly mounted on the bottom end of the car support base 3. One end of the fixed shaft 61 has a pin slot. The pin on the self-locking contact 64 cooperates with the pin key slot of the fixed shaft 61, so that the self-locking contact 64 can only slide left and right but not rotate or slide. The bottom side of the car support shaft 11 is connected to the car 6.

[0088] When the car support seat 3 drives the car 6 to move up and down along the straight rail 22 through the car bearing shaft 11, the car 6 drives the car bearing shaft 11 to deflect at a certain angle around the fixed axis 61 under the action of gravity. The contacts on the self-locking contacts 64 are locked with the grooves on the car bearing shaft 11, thereby vertically locking the car 6 at a fixed angle between the vertical and horizontal planes, preventing the car from shaking due to passenger shaking.

[0089] When the car support seat 3 moves to the intersection of the straight rail 22 and one end of the flat semicircular track 20, the car reversing contact 71 installed between the two tracks will toggle the toggle rod 62 installed on the car support seat 3 to produce a certain angle of deflection. A cable 63, one end of which is fixed to the toggle rod 62 and the other end is fixed to the self-locking contact 64, will drag the self-locking contact 64 to shift to the right. At this time, the contact on the self-locking contact 64 will disengage from the groove on the car bearing shaft 11. The car support seat 3 changes from cooperating with the straight rail 22 to cooperating with the flat semicircular track 20. Under the action of its own gravity, the car bearing shaft 11 and the car 6 begin to rotate around the fixed axis 61 installed on the car support seat 3. When the car rotates again to be perpendicular to the horizontal plane, the toggle rod 62 surpasses the car reversing contact 71, and the toggle rod 62 returns to its initial state under the action of the reset spring 65. At this time, the self-locking contact 64 slides to the left under the action of the reset spring and locks with another groove of the car load-bearing shaft 11. The car load-bearing shaft 11 stops rotating, completing the second reversing action.

[0090] As the car support seat 3 continues to move, the toggle rod 62 will disengage from the car reversing contact 71 fixed at the intersection of the two tracks. Under the reaction force of the reset spring 65, the toggle rod 62 returns to its initial position. At this time, the contact on the self-locking contact 64 will cooperate with the new groove on the car bearing shaft, and the car 6 will be locked at the new angle, so that the car will always remain perpendicular to the horizontal plane and will not deflect or shake.

[0091] The power transmission device 2, car support base 3, and universal connecting rod base 4 are sequentially connected by universal connecting rods 7, with each of them connected to the track 8 with a certain distance between them. When the elevator descends, the power transmission device 2 transmits power to each car in turn through the universal connecting rod 7, pushing the car support base 3 to drive the car 6 to move downward on the horizontal semicircular track 20 in the opposite direction. This prevents the rear car 6 from stopping at the level position due to loss of gravity, ensuring that both the ascent and descent of the car can be completed with a single power source.

[0092] See also Figure 3 、 Figure 4 The car is provided with an upper folding joint 12, a middle folding joint 13 and a folding pedal 15. The length of the upper folding joint 12 is similar to that of the folding pedal 15. The connection between the folding pedal 15 and the car column 17 and the lower folding column 77 is equipped with four hinges and can rotate freely. When the passenger gets off the elevator, the upper folding joint 12 is acted upon by the return spring or the drive motor, and the upper folding column 76 is closed inward, and the middle folding joint 13 starts to rotate, driving the lower folding column 77 to connect the pedal to close inward. When the upper folding joint 76 is closed to be parallel to the horizontal plane, the folding pedal 15 and the lower folding column 77 are in an upright state. At this time, the car is completely folded.

[0093] See also Figure 14 The universal connecting rod 7 is composed of two parts: a spherical body 56 and a connecting rod 57. The spherical body 56 is respectively connected to the universal connecting rod fixing groove 45 on the power transmission device 2, the car support seat 3, and the universal connecting rod seat body 4. In this way, it can ensure that the power transmission device 2, the car support seat 3, and the universal connecting rod seat body 4 run smoothly when passing through the leveling semicircular track 20 and the intersection of the leveling semicircular track 20 and the straight rail 22, and prevent the occurrence of uneven running track.

[0094] See also Figure 18 The rail sleeper 74 includes a positioning screw hole 66, a bolster body 67, and a clamp 68. The clamp 68 is a right-angled clip, approximately 5-10 cm long, and is installed at a right angle to the front step of the stair 73, forming a tight fit. The width of the rail sleeper 74 is substantially the same as the width of the stair surface. The installation method is as follows: After the clamp 68 is inserted into the right-angle step of the stair 73, the bolster body 67 is aligned with the back of the stair 73, and the positioning screw hole 59 is fixed to the wall using expansion screws. This ensures that the rail sleeper 74 has a large load-bearing capacity and does not affect pedestrians walking normally on the stair surface.

[0095] See also Figure 20 , Figure 20This diagram simulates the pedal operation during an elevator turn at level ground. The pedal measures approximately 50 cm long and 30 cm wide, and the radius of the semicircular track at level ground is approximately 50 cm. In this state, four elevator cars can simultaneously turn at the same level. This diagram simulates the cornering process without the cars touching each other. If more cars are required, they should be arranged with the same spacing between them.

[0096] See also Figure 21 , Figure 21 The following is a diagram of the elevator's logic operation. Its operating principle is that when someone on any floor presses the up / down selection button 70, a signal is sent to the elevator's electrical control system. The control system then sends the selection instruction to the logic control and distribution circuit, which then determines the direction of the elevator's operation based on the floor the elevator is currently on. For example, if a passenger presses the button on the third floor, while the elevator is on the first floor, the logic control circuit determines that the motor needs to rotate in the forward direction. After this determination, the control circuit sends a command signal to the traction motor via the safety circuit, causing the traction motor to rotate in the forward direction, thus completing the upward movement. When the power transmission device 2 reaches a level floor, a leveling signal is sent to the elevator control system. The control system then determines that the motor needs to stop and sends a stop signal to the traction motor. Upon receiving the command, the traction motor stops, completing the elevator's arrival at the destination. After the elevator arrives at the station, the passenger gets on the elevator and presses the floor selection button 10 for the first floor. The floor selection button 10 will send the signal of the floor to be reached to the elevator electrical control system. The elevator electrical control system will send the signal to the logic control and distribution circuit. According to the logical relationship between the third floor and the first floor, it is determined that the motor needs to move in the reverse direction, and the electrical signal is sent to the traction motor 39 through the protection circuit. After receiving the command, the traction motor 39 starts to move in the reverse direction, and the power transmission device 2 drives the car to move downward. When the elevator reaches the first floor, the leveling arrival signal will be sent to the elevator electrical control system. After receiving the leveling signal, the elevator electrical control system will transmit a stop command to the traction motor. After receiving the command, the traction motor 39 will stop rotating, completing the descending action and completing a passenger transportation process.

[0097] The elevator electrical control box 69 is installed on the middle floor of each building. Its purpose is to save cable length. The cable winch 5 only needs to twist half of the cable to achieve the purpose of controlling the operation of the elevator.

[0098] The outer layers of the positioning rail wheels 43 and the hollow rail wheels 53 are provided with a rubber layer, the purpose of which is to reduce the noise between the positioning rail wheels 43, the hollow rail wheels 53 and the rail 8 when the elevator is running, thereby improving the quietness of the elevator during operation.

[0099] Because the staircase in the old residential building only reaches the level of the 6th floor, it is not possible to install the rail sleeper beam 74 to enable the elevator to reach the 6th floor or other top floors. In order to achieve the purpose of the elevator reaching the 6th floor or other top floors, an extension rail beam 78 ( Figure 22 ) to the 6.5th floor, one end of the extended track beam 78 is connected to the 6th-floor leveling semicircular track 20, and the other end is connected to the 6.5-floor semicircular track 20. The other end of the semicircular track 20 is connected to one end of the second extended track beam 78, and the other end of the extended track beam 78 is fixed to the roof 79 of the top floor. The purpose of this is to install the extended track beam 78 and install the track 8 below the extended track beam 78, so that the track is laid out at the top floor, ultimately achieving the purpose of leveling the floor.

[0100] The structure also has the following safety protection measures:

[0101] one, Figure 10 This circuit protection device operates as follows: When the elevator car 6 is folded, the fixed-side car contact 41 contacts the car column 17 of the car 6, squeezing the contact 41 on the double-control switch 38 and completing the circuit. This energizes the traction motor 39, allowing the elevator to operate in the folded state. When a passenger presses the up / down button, the traction motor 39 can then operate normally. When a passenger needs to take the elevator, the elevator car 6 is opened. At this time, the contact 41 on the double-control switch 38 loses its compression. Under the action of the return spring in the double-control switch 38, the entire circuit is disconnected. At this time, whether the up or down floor selection button 70 is pressed on other floors or the floor selection button 10 is pressed on the current floor, the entire circuit is in the disconnected state, and the traction motor 39 does not work. This ensures that the elevator does not move before the deployment is completed and remains in a stationary state to prevent accidental injury to personnel. When the elevator car 6 is fully deployed and the passenger enters the car, the elevator circuit is still in the disconnected state and cannot go up or down. The passenger needs to pull the handrail 14, which moves in a circle around the folding handrail fixing seat 40. The lower end of the handrail 14 will squeeze the contact 42 on the double-control switch 38, at which point the double-control switch 38 is triggered, and the entire circuit is connected. After the passenger presses the floor selection button, the elevator moves up or down according to the set floor. This solution can ensure the safety of elevators used by multiple people.

[0102] 2. Infrared switches 19 are installed on the front and rear sides of the folding pedal 15 of the car 6. One side of the folding pedal is an infrared light source and the other side is a reflector. When a passenger's limbs or foreign objects accidentally touch the front and rear sides of the pedal 15, the infrared reflector cannot reflect the infrared light. At this time, the entire circuit is disconnected, thereby ensuring that the elevator stops running when the car encounters an obstacle during travel or when a passenger accidentally touches the outer edge of the pedal 15, thereby preventing the risk of squeezing and ensuring the safety of the elevator during travel.

[0103] 3. An overspeed locking device is installed on each car support 3. When the universal connecting rod 7 breaks, or other components such as the power transmission device 2, the car support 3, and the universal connecting rod base 4 are damaged, the entire elevator can be instantly locked to prevent the accidental detachment of a car and ensure the safety of the elevator operation.

[0104] Fourth, the power transmission device 2, the car support seat 3, and the universal connecting rod seat body 4 are connected in series through steel cables. The purpose is to ensure that the cars can still be connected to each other when the universal connecting rod 7 breaks or other unexpected situations occur, thereby ensuring that the car will not slip.

[0105] 5. A tension sensor is installed on each car support seat 3. When the car load exceeds the specified value, the entire circuit is disconnected and an alarm is issued to remind passengers not to overload.

[0106] Sixth, each car is equipped with front and rear folding guards 18. One side of the folding guard 18 is connected to the car column 17 via a joint, while the other side is hollowed out in the middle, sliding around the lower folding column 77. This allows the front and rear folding guards 18 to slide along the hollow track at their fixed points to the lower folding column 77 when the car is deployed, while the other side moves in a circular motion with the car column 17, slowly deploying. This ensures that passengers are shielded from view while riding the elevator, ensuring their safety. When passengers exit the elevator, the car folding lever automatically folds under the force of the return spring.

[0107] The specific operating method of the present invention is:

[0108] When a passenger on any floor needs to go up or down, they press the up or down button to summon the elevator. Upon receiving the command, the elevator automatically determines whether to move up or down based on logic. When the elevator reaches the passenger's floor, it automatically stops and enters a waiting state, with the car folded. The passenger then swipes their card to command the elevator to deploy. Once the car is fully deployed, the passenger enters and closes the folding handrails, placing the circuit in a standby state. The passenger then presses the button for the desired floor. Upon receiving the command, the elevator automatically determines whether to move up or down, and stops upon reaching the desired floor.

[0109] Upon reaching the destination floor, the passenger opens the folding handrail 14, de-energizing the circuit. After the passenger exits the elevator car, the folding footboard 15 automatically folds, driven by a return spring or motor installed in the upper folding joint 12. Before the folding footboard 15 is fully folded, the double switch is disconnected, and the entire elevator is stopped. Regardless of whether other passengers press the up or down floor selector buttons, or whether other passengers press the floor selector buttons, the entire elevator remains stopped, ensuring that the elevator remains stopped during the folding process.

[0110] The above description is only a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent replacement or change made by any technician familiar with the technical field within the technical scope disclosed by the present invention based on the technical solution and novel concept of the present invention should be covered by the scope of protection of the present invention.

Under the push of the traction motor, the elevator is driven to achieve upward or downward movement on the straight rail. The first gear installed on the vertically separated transmission shaft assembly has no rack on the side of the straight track, resulting in idling. When the power transmission device reaches the position of the flat semicircular track, an overlapping rack is provided at the intersection of the straight track and the flat semicircular track. Therefore, when the power transmission device transitions from the straight track to the flat semicircular track, the first gear and the second gear installed on the vertically separated transmission shaft assembly and the horizontally separated transmission shaft assembly simultaneously cooperate with the rack fixed on the straight track and the flat semicircular track to achieve the transition of the power transmission device from the straight track to the flat semicircular track. After the overlapping rack transition is completed, since the leveling semicircular track is only equipped with an arc-shaped rack on the side and no rack is installed on the top, the first gear on the vertically separated transmission shaft assembly cooperates with the arc-shaped rack. At this time, the horizontally separated transmission shaft assembly is supported by the hollow track wheel, and the second gear is idle. At this time, the power transmission device is driven by the first gear on the vertically separated transmission shaft assembly to achieve leveling turning; When the power transmission device runs to the connection between the end of the flat semicircular track and the beginning of the straight track, a rack is laid out at the same time to form an overlapping area. After the power transmission device passes through the overlapping area, the first gear on the vertically separated transmission shaft assembly becomes idle, and the driving force is converted into the second gear installed on the horizontally separated transmission shaft assembly to cooperate with the rack on the straight track to drive the elevator up or down. The power transmission device realizes the reversal from the flat semicircular track to the straight track.
