Description

Technical Field

[0001] The present invention relates to the technical field of elevator equipment, and more particularly to a foldable elevator shaft and car. Background Art

[0002] According to statistics, there are 7 million elevators in use nationwide, and 3 million units in older buildings suitable for installation. In particular, existing units suitable for elevator installation can only use outdoor shafts, with corridors transitioning to the existing building's corridor corner platforms. Over 80% of units have upper-floor platforms for entry. Adding elevator shafts and corridors to the exterior of existing buildings disrupts the original residential planning, obstructing existing access and even affecting fire escape routes. It also negatively impacts the building's appearance, lighting, and ventilation. Furthermore, the half-floor corner platform connection presents a cumbersome challenge for wheelchair users.

[0003] Chinese patent publication number CN110182670B discloses a bottom-suspended external shaft elevator system, which belongs to the field of elevator technology. It includes an elevator shaft, a car, a car guide rail, a machine room control system, a counterweight, a counterweight guide rail, a buffer mechanism and a lower guide limit device. The elevator shaft is bottom-suspended. Under special circumstances, the car can be assisted by the lower guide limit device to descend to the ground floor. Through side buffers, impact beams are installed on both sides of the top of the car frame to replace the buffer pit at the bottom of the car. The proposed building external shaft elevator system can be applied to a variety of building configurations. However, it has the disadvantage of adversely affecting the appearance, lighting and ventilation of the original building. Summary of the Invention

[0004] In order to overcome the above problems, a foldable elevator shaft and car are provided, which can enable wheelchair users to go up and down stairs normally while ensuring the normal use of fire escape routes and without adversely affecting the original building's appearance, lighting, and ventilation.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions: a foldable elevator shaft and car, including a foldable shaft and car, the shaft is composed of a plurality of shaft units arranged between each floor, the shaft unit is composed of a shaft door, a tailgate, and side wall units arranged on both sides of the shaft door and the tailgate, the side wall unit includes a plurality of side wall component units arranged in sequence along the corridor step surface, the side wall component unit includes a strip wall arranged between the upper and lower corridor steps on the same side, a variable pedal hingedly arranged between the strip wall and the lower corridor step, and a suspension mechanism hingedly arranged between the strip wall and the upper corridor; a first driving device can connect the hingedly connected strip walls on each side wall component unit in the side wall unit to each other into a whole, so as to realize synchronous driving of each side wall component unit to fold or unfold; an elevator guide rail and a car are provided in the shaft, and the car includes a fixed car body arranged on the elevator guide rail and a car body folding component arranged on both sides of the fixed car body; a second driving device is arranged on the fixed car body, and can drive the car body folding component to realize folding, stowing or unfolding.

[0006] Due to limited space in some older residential communities, installing elevators is difficult. The solution proposed by the present invention is to install the elevator shaft within the original corridor. Specifically, the center of the original corridor (the side not facing the wall) is partially cut and removed, creating a space from bottom to top in the corridor for installing the elevator shaft. The elevator guide rails differ from the conventional arrangement of guide rails on both sides of the car. Instead, they adopt a backpack-style structure, with a single guide rail located on the back of the car. This allows the shaft sidewalls to be folded inward without being blocked by the guide rails. Considering that when the shaft sidewalls fold inward, the previously cut corridor will create a large gap, the present invention employs foldable sidewalls to fill this gap. Specifically, the shaft sidewall unit is designed with a foldable sidewall assembly unit based on the width of the corridor steps. The function of this sidewall assembly unit is that when the shaft is folded, the structural unit is straight and contracts toward the center. When the shaft is opened, the structural unit forms an L-shape and is pushed outward, with the bottom portion becoming the corridor steps and the middle portion remaining as the shaft sidewall. Each side wall unit in the entire shaft is composed of a number of side wall assembly units arranged in an arrangement, the number of units matches the number of corridor steps, and the strip walls of each unit are fixed to each other into a whole to improve the strength of the entire side wall; the present invention can fold the shaft and the car when the fire escape is needed, thereby ensuring the normal use of the fire escape; and when the fire escape is not in use, the shaft and the car are normally unfolded for users to use, and this solution will not cause adverse effects on the original building's appearance, lighting, and ventilation; this solution does not elaborate on the limit fixation of the unfolded or folded parts of the shaft and the car, and does not specifically expand on this part. This part belongs to the existing technology and will not be explained in detail in this solution.

[0007] Preferably, the suspension mechanism includes a suspension mount and several suspension rotatable members. The suspension mount includes a fixed body fixed to the stairway step and several connectors mounted on the fixed body. One end of the suspension rotatable member is hingedly connected to the connector, and the other end of the suspension rotatable member is hingedly connected to the strip wall. The suspension mechanism has a three-section hinge structure, with its ends hingedly connected to the stairway step and the strip wall, respectively. This structure facilitates the folding and coordination of the suspension rotatable members connected to the suspension mount and the strip wall, thereby achieving folding and unfolding of the side wall assembly unit.

[0008] Preferably, the variable pedal has a three-section hinge structure, with its ends hingedly connected to the stairway steps and the strip wall, respectively. A long tail section is provided in the middle section of the strip wall end. This long tail section serves as a limiter when the shaft sidewall unit is opened. The variable pedal forms part of the shaft sidewall unit when the shaft is open, and forms part of the stairway steps when the shaft is folded.

[0009] Preferably, the suspension rotating member includes a rotating section and a stop section disposed at the end of the rotating section. The rotating section and the stop section, when connected, form an L-shaped structure. The suspension rotating member is hingedly connected to a rotating shaft on the stop section near one side of the rotating section, wherein the rotating section is connected to the strip-shaped wall. The stop section on the suspension rotating member serves as a stop when the hoistway side wall unit is folded.

[0010] Preferably, the driving device 1 includes a driving motor 1 provided on the shaft door, a main transmission shaft provided on the output shaft of the driving motor 1, a mounting seat provided on the connecting body, the main transmission shaft being rotatably connected to the mounting seat, a bevel gear 1 provided on the main transmission shaft, and a bevel gear 2 meshingly connected with the bevel gear 1 provided on the main transmission shaft provided on one end of the rotating shaft. The initial state is the unfolded state. When the side wall unit needs to be folded, the driving motor 1 is first started. The driving motor 1 starts to drive the main transmission shaft to rotate, thereby driving the bevel gear 2 to rotate. The rotation of the bevel gear 2 drives the bevel gear 1 to rotate, thereby driving the suspension rotating member to rotate. When the suspension rotating member rotates to a certain angle, the limit section on the suspension rotating member starts to limit, preventing further folding and adjustment. At the same time, the strip wall and the variable pedal also rotate and unfold with the rotation of the suspension rotating member, thereby realizing the folding and unfolding of the shaft side wall unit. The unfolding of the variable pedal can realize the widening of the corridor steps.

[0011] Preferably, the car body folding assembly includes a foldable car body floor, car body roof, car body wall, car body back, and car door. The fixed car body is in a "C" shape.

When the car structure in this solution needs to be folded, the car back and the car door need to be folded and retracted first, and then the car bottom, car top and car wall are folded and retracted; when the car bottom, car top and car wall in the car folding assembly need to be folded, the driving motor 2 is started first, and the output shaft of the driving motor 2 rotates to drive the gear 1 to rotate, thereby driving the rack push rods on the upper and lower sides of the gear 1 to slide along the guide seat, thereby driving the car top, car wall and car bottom to be folded and retracted.

[0013] Preferably, the second drive assembly includes a third drive motor mounted on the car wall and a first transmission belt assembly. The first transmission belt assembly is used to connect the car door to the output shaft of the second drive motor. When the car door needs to be folded and retracted, the third drive motor is activated. The output shaft of the third drive motor rotates, driving the first transmission belt assembly. The first transmission drives the door shaft connected to the car door and the car wall to rotate, thereby driving the car door to fold and retract toward the inside of the car.

[0014] Preferably, the drive assembly 3 includes a drive motor 4 mounted on the fixed body and a plurality of transmission belt sets 2. The transmission belt sets 2 are used to connect the back of the vehicle to the output shaft of the drive motor 4.

The output shaft of the drive motor 4 rotates to drive the transmission belt set 2, which then drives the two backs connected to the fixed body to fold inward.

[0015] Preferably, the hoistway door comprises a C-shaped door frame and a V-shaped door disposed within the C-shaped door frame. The C-shaped door frame is provided with rotational fulcrums at the upper and lower portions near the C-shaped opening, and the left and right hoistway doors are symmetrically mounted in parallel. A control device is provided at the top of the stairway platform where the hoistway door is located, and the upper and lower sides of the rotational fulcrum are connected to the control device and the stairway platform where the hoistway door is located, respectively. The control device can control the C-shaped door frame and the V-shaped door to fold or open, or can control the V-shaped door alone to fold and open. This control device is prior art and will not be described in detail here.

[0016] Compared with the prior art, the beneficial effects of the present invention are: when the fire passage needs to be used, the shaft and the car can be folded, thereby ensuring the normal use of the fire passage; and when the fire passage is not in use, the shaft and the car are normally unfolded for users to use, and this solution will not have an adverse effect on the appearance, lighting and ventilation of the original building.

[0030] The variable pedal 7 has a three-section hinge structure, with its ends hingedly connected to the stair step 1.1 and the strip wall 6, respectively. The middle section of the strip wall 6 is provided with a long tail section 15. The suspension mechanism 8 also has a three-section hinge structure, with its ends hingedly connected to the stair step 1.1 and the strip wall 6, respectively. The long tail section 15, provided in the middle section of the strip wall 6, acts as a limiter when the shaft sidewall unit 5 is opened. When the shaft is open, the variable pedal 7 forms part of the shaft sidewall unit; when the shaft is folded, the variable pedal 7 forms part of the stair step 1.1. The suspension mechanism 8 includes a suspension bracket 16 and several suspension rotatable members 17. The suspension bracket 16 includes a fixed body 18 fixed to the stair step 1.1 and several connectors 19 provided on the fixed body 18.

This structure facilitates the folding and coordination of the suspension rotating member 17 connected to the suspension fixing frame 16 and the strip wall 6, thereby achieving the folding and unfolding of the side wall assembly unit 5. The suspension rotating member 17 includes a rotating section 20 and a limiting section 21 disposed at the end of the rotating section 20. The rotating section 20 and the limiting section 21 are connected to form an "L"-shaped structure. The suspension rotating member 17 is hingedly connected to a rotating shaft 22 on the limiting section 21 near the side of the rotating section 20, wherein the rotating section 20 is connected to the strip wall 6. The limiting section 21 on the suspension rotating member 17 serves as a limiter when the hoistway side wall unit is folded.

The initial state is the unfolded state. When the side wall unit needs to be folded, the drive motor 1 23 is started first. The drive motor 1 23 starts to drive the main transmission shaft 24 to rotate, thereby driving the bevel gear 2 28 to rotate. The rotation of the bevel gear 28 drives the bevel gear 1 26 to rotate, thereby driving the suspension rotating member 17 to rotate. When it rotates to a certain angle, the limit section 21 on the suspension rotating member 17 starts to limit, preventing further folding and adjustment. At the same time, the strip wall 6 and the variable pedal 7 also rotate and unfold with the rotation of the suspension rotating member 17, thereby realizing the folding and unfolding of the shaft side wall unit. The unfolding of the variable pedal 7 can realize the widening of the corridor steps 1.1.

[0032] The car body folding assembly 13 includes a foldable car body bottom 30, a car body roof 31, a car body wall 32, a car body back 33 and a car door 34. The fixed car body has a "C"-shaped structure. The car body bottom is hingedly connected to the lower end of the fixed car body 12, the car body roof 31 is connected to the upper end of the fixed car body 12, and the car body wall 32 is hingedly connected to the car body roof 31 and the car body bottom 30 at the upper and lower ends respectively. One end of the car body wall 32 is hingedly connected to the car door 34, and the car body back 33 is hingedly connected to the fixed car body 12 on the side away from the car door 34. The fixed car body 12 in this structure is the main part of the car 11. The car 11 is folded and stowed by the car body folding assemblies 13 on both sides of the fixed car body 12. There are door shafts at the upper and lower edges of the car door 34, and the door shafts are installed in conjunction with the shaft seats at the front edge of the car wall 32. The upper and lower ends of the car wall 32 are hinged to the edges of the car bottom 30 and the car roof 31. A vertical edge of the car back 33 is hinged to the fixed car body 12 and can be fan-shaped and closed. The folding method and steps of the car 11 are as follows: first, the car door 34 is fan-shaped and retracted so that the car door 34 is close to the car wall 32. At the same time, the car back 33 is fan-shaped and closed toward the middle of the car 11. Then the car wall 32 is lifted upward. While the car wall 32 is lifted upward, it also moves closer to the middle of the car 11 to complete the folding. The upward lifting action is achieved by a device arranged on the top of the load-bearing frame using a steel cable traction method.

[0033] The driving device 2 14 includes a driving component 1 35, a driving component 2 36 and a driving component 3 37. The driving component 1 35 includes a driving motor 2 38 arranged on the fixed box body 12, a gear 1 39 arranged on the output shaft of the driving motor 2 38, and a transmission mechanism 40. The transmission mechanism 40 includes a guide seat 41, a connecting seat 42 arranged on the box top 31 on both sides of the guide seat 41, two groups of rack push rods 43 slidingly arranged in the guide seat 41 and a connecting rod 44 hingedly arranged between the rack push rod 43 and the connecting seat 42, wherein the two groups of rack push rods 43 are respectively arranged on the upper and lower sides of the gear 1 39, and are meshed and connected with the gear 1 39. When the car 11 structure in this solution needs to be folded, the car back 33 and car door 34 should be folded and stowed first, and then the car bottom 30, car roof 31, and car wall 32 should be folded and stowed. When the car bottom 30, car roof 21, and car wall 32 in the car folding assembly 13 need to be folded, the drive motor 2 38 is first started. The output shaft of the drive motor 2 38 rotates, driving the gear 1 39 to rotate, thereby driving the rack push rods 43 on the upper and lower sides of the gear 1 39 to slide along the guide seat 41, thereby driving the car roof 31, car wall 32, and car bottom 30 to fold and stow. The drive assembly 2 36 includes a drive motor 3 45 and a transmission belt assembly 1 46 arranged on the car wall 32. The transmission belt assembly 1 46 is used for the transmission connection between the car door 34 and the output shaft of the drive motor 3 45. When the car door 34 needs to be folded and retracted, the drive motor 3 45 is first started. The output shaft of the drive motor 3 45 rotates, driving the transmission belt set 1 46 for transmission. The transmission belt set 1 46 drives the door shaft connected to the car door 34 and the car wall 32 to rotate, thereby driving the car door 34 to fold and retract toward the inside of the car 11. The drive assembly 37 includes a drive motor 47 and a plurality of transmission belt sets 2 48 provided on the fixed car body 12.

When the car back needs to be folded and retracted, the drive motor 4 47 is first started. The output shaft of the drive motor 4 47 rotates, driving the transmission belt set 2 48. The transmission belt set 2 48 drives the two car backs 33 connected to the fixed car body 12 to fold and retract inward.

[0034] Hoistway door 2 comprises a C-shaped door frame 49 and a V-shaped door 50 disposed within the C-shaped door frame 49. Rotational fulcrums 52 are provided at the upper and lower portions of the C-shaped opening of the C-shaped door frame 49, with the left and right hoistway doors mounted symmetrically and in parallel. A control device 51 is provided at the top of the stairway platform where hoistway door 11 resides. The upper and lower sides of the rotational fulcrum 52 are connected to the control device 51 and the stairway platform where hoistway door 2 resides, respectively. The control device 51 can control the folding or opening of the C-shaped door frame and V-shaped door 50, or can control the folding and opening of the V-shaped door 50 alone. This control device is conventional and will not be described in detail here.

[0035] Workflow:

[0036] This solution provides a foldable elevator shaft and car. Due to the limited space in some old residential areas, it is difficult to install elevators. The solution proposed by the present invention is to set up the elevator shaft in the original corridor, that is, to partially cut and remove the middle of the original corridor (the side not against the wall), so that a space for installing the elevator shaft is freed up from the bottom to the top of the corridor. The elevator guide rails are different from the usual solution of being set on both sides of the car. Instead, they adopt a backpack structure, that is, a single guide rail is set on the back of the car, so that the side walls of the shaft are not blocked by the guide rails when folding inward. Taking into account that when the side walls of the shaft are folded inward, a large gap will be formed by the originally cut and removed staircase, the present invention adopts a foldable side wall to fill the gap, that is, the shaft side wall unit is designed to have a foldable side wall component unit according to the width of the staircase steps. The function of the side wall component unit is that when the shaft is folded, the structural unit is in a straight state and its position is contracted and moved closer to the middle; when the shaft is opened, the structural unit is in an L-shaped state and its position is pushed outward, wherein the lowermost part becomes the staircase step, and the middle part remains the shaft side wall. Each side wall unit in the entire shaft is composed of a number of side wall assembly units arranged in an arrangement, the number of units matches the number of corridor steps, and the strip walls of each unit are fixed to each other into a whole to improve the strength of the entire side wall; the present invention can fold the shaft and the car when the fire escape is needed, thereby ensuring the normal use of the fire escape; and when the fire escape is not in use, the shaft and the car are normally unfolded for users to use, and this solution will not cause adverse effects on the original building's appearance, lighting, and ventilation; this solution does not elaborate on the limit fixation of the unfolded or folded parts of the shaft and the car, and does not specifically expand on this part. This part belongs to the existing technology and will not be explained in detail in this solution.

[0037] The folding method and steps of the car 11 are as follows: first, the car door 34 is fanned up so that the car door 34 is close to the car wall 32, and at the same time, the car back 33 is fanned and closed toward the middle of the car 11, and then the car wall 32 is lifted upward. As the car wall 32 is lifted upward, it also moves toward the middle of the car 11 to complete the folding. The upward lifting action is achieved by a device installed on the top of the load-bearing frame using a steel cable traction method. The specific implementation is as follows: first, the car door 34 and the car back 33 are folded and retracted. When the car door 34 needs to be folded and retracted, the drive motor 34 is first started. The output shaft of the drive motor 35 rotates to drive the transmission belt assembly 1 46. The transmission belt assembly 1 46 drives the door shaft connected to the car door 34 and the car wall 32 to rotate, thereby driving the car door 34 to fold and retract toward the inside of the car 11. When the backrest 33 needs to be folded and stowed, the drive motor 47 is first started. The output shaft of the drive motor 47 rotates to drive the transmission belt set 2 48, which drives the two sets of backrests 33 connected to the fixed body 12 to fold inward. Then the bottom 30, roof 31, and walls 32 are folded and stowed. When the bottom 30, roof 31, and walls 32 in the body folding assembly 13 need to be folded, the drive motor 2 38 is first started. The output shaft of the drive motor 2 38 rotates to drive the gear 1 39, thereby driving the rack push rods 43 on the upper and lower sides of the gear 1 39 to slide along the guide seat 41, thereby driving the roof 31, walls 32, and bottom 30 to fold and stow.

[0038] When the shaft side wall unit needs to be folded, the side wall is lifted up by the driving device 9 and simultaneously moved toward the middle under the constraints of the variable pedal 7 and the suspension mechanism 8. The rear baffle 3 of the shaft is connected to the last end side wall unit 4. When the side wall 32 is lifted and moved together, the left and right rear baffles 3 move toward each other and cross-overlap to complete the folding. The folding mechanism on each floor can be opened and folded manually and electrically controlled. The specific drive is as follows, that is, first start the drive motor 23, the drive motor 23 starts to drive the main transmission shaft 24 to rotate, thereby driving the bevel gear 2 28 to rotate, the rotation of the bevel gear 28 drives the bevel gear 1 26 to rotate, thereby driving the suspension rotating member 17 to rotate, when it rotates to a certain angle, the limit section 21 on the suspension rotating member 17 starts to limit, preventing further folding and adjustment, at the same time, the strip wall 6 and the variable pedal 7 also rotate and unfold with the rotation of the suspension rotating member 17, thereby realizing the folding and stowing of the side wall unit 4, and the unfolding of the variable pedal 7 can realize the widening of the corridor steps 1.1, and each drive motor 23 needs to be driven synchronously.

[0039] The above-described embodiments are only preferred solutions of the present invention and are not intended to limit the present invention in any form. Other variations and modifications are possible without exceeding the technical solutions described in the claims.
