Description

Technical Field

[0001] This utility model belongs to the technical field of elevator car, and in particular relates to an elevator car structure and an elevator. Background Technology

[0002] Currently, existing elevator car structures, such as the "car bottom wheel, car frame, and elevator" proposed in patent publication number CN222770435U, generally adopt a two-part design where the car and car frame are independent of each other. The car frame, as the main load-bearing component, supports the car bottom platform via brackets, and the overall load is borne by straight beams connected to the brackets. However, this structural design inevitably requires a significant amount of vertical and horizontal installation space for the brackets and straight beams, resulting in a large and less compact overall elevator car structure. Furthermore, the multi-component car frame complicates the overall structure, increasing the installation process and difficulty, requiring more manpower and time, ultimately slowing down the overall elevator installation progress and extending the installation cycle. Utility Model Content

[0003] In view of this, it is necessary to provide an elevator car structure and elevator that is simple in structure, has few parts, and is easy to install.

[0004] An elevator car structure, comprising: The car, including the platform underneath; Multiple straight beams are provided on two opposite sides of the car bottom platform and are respectively connected to the car bottom platform, and at least a portion of each straight beam constitutes part of the car wall; The rear side wall and the front side wall are provided on both sides of each of the straight beams and are respectively connected to the corresponding straight beams and the car bottom platform; and the rear side wall, the straight beams and the front side wall together constitute the car side wall of the car.

[0005] Understandably, by using straight beams that also function as car walls to directly support the car bottom platform, the traditional independent car frame structure is eliminated, thus achieving an integrated design for the elevator car structure. On the one hand, while bearing the load-bearing function, the straight beams also integrate the structural function of the side and center walls. This design not only eliminates the need for independent side and center wall components, but also effectively reduces the space occupied by the elevator car structure in the horizontal direction and the number of components, thereby reducing the space occupied by the elevator car structure in both the vertical and horizontal directions and effectively improving the utilization rate of the shaft space. On the other hand, the simplification of the structure reduces the number of components and the complexity of assembly, making the installation process more convenient and shortening the installation cycle.

[0006] In one embodiment, the straight beam is configured as a bent plate; The two sides of the straight beam are bent in the direction away from the rear side wall and the front side wall respectively to form a first bent part and a second bent part. The first bent part is attached to and connected to the rear side wall, and the second bent part is attached to and connected to the front side wall.

[0007] In one embodiment, the lower end of the straight beam extends to a position flush with the car floor platform, and the extended wall of the straight beam abuts against the outer surface of the car floor platform and is connected to the car floor platform. The straight beam and the car bottom platform are connected together by a safety clamp, wherein the safety clamp is assembled to the extension wall by fasteners, and the fasteners pass through the side of the extension wall and the car bottom platform in sequence.

[0008] Understandably, by using the straight beam and the car bottom platform to jointly support the safety gear, a high-strength integrated load-bearing mechanism for the safety gear can be achieved. This effectively disperses and supports the enormous force generated by the safety gear during braking through the stable frame constructed by the straight beam and the car bottom platform, thereby significantly improving the installation strength of the safety gear and ensuring that it can reliably meet the stringent requirements of high-load braking. This eliminates the car bottom bracket structure in existing technologies, merging the car bottom platform and the car bottom bracket, resulting in the car bottom platform occupying less height space and greatly reducing the required depth of the shaft pit.

[0009] In one embodiment, the elevator car structure further includes guide shoes and safety clamps; The safety clamp is mounted on the extension wall of the straight beam extending to the car floor platform; The guide shoe is located below the safety clamp and is mounted on the bottom surface of the car platform.

[0010] In one embodiment, the guide shoe is mounted on the bottom surface of the car floor platform via a guide shoe seat; The guide shoe seat has a central reinforcing rib, and a support rib plate is provided on the car bottom platform. The support rib plate is located directly above the central reinforcing rib and is used to support the guide shoe seat.

[0011] In one embodiment, the car floor platform includes a car floor plate, a car floor frame, multiple load-bearing beams and multiple reinforcing ribs. The multiple load-bearing beams are assembled on the car floor plate, and the multiple reinforcing ribs are disposed on the side of the multiple load-bearing beams away from the car floor plate and assembled on the car floor frame. Each of the load-bearing beams is connected to a plurality of the reinforcing ribs, and each of the reinforcing ribs is connected to a plurality of the load-bearing beams.

[0012] Understandably, by arranging the reinforcing ribs and load-bearing beams in an alternating pattern, a stable mesh support structure is formed beneath the car floor platform. This design effectively distributes and disperses local loads, significantly improving the bending and deformation resistance of the car floor platform, thereby enhancing its overall structural strength and rigidity.

[0013] In one embodiment, the car floor frame is disposed around the car floor panel and connected to the car floor panel; The load-bearing beam is bent on both sides and each forms a connecting plate portion. The two connecting plates portions are attached to the car floor plate and connected to the car floor plate. Both ends of the reinforcing rib are housed within the car bottom frame and connected to the car bottom frame.

[0014] In one embodiment, the elevator car structure further includes a buffer plate; The buffer plate is located at the center of the car floor platform and is connected to the reinforcing rib.

[0015] In one embodiment, the buffer plate rests against the bottom surface of the reinforcing rib; A buffer impact plate bracket is connected between the side walls of the two reinforcing ribs, and the buffer impact plate bracket connects to and supports the buffer impact plate.

[0016] In one embodiment, the car also includes a car roof, which is disposed between the plurality of straight beams and connected to each of the straight beams respectively; The multiple straight beams are also connected by an upper beam, on which a car top wheel is provided.

[0017] Understandably, by using the straight beam as the main load-bearing component and directly connecting its two ends to the car top and car bottom platforms, a complete force transmission frame can be constructed. This design enables the load to be transmitted efficiently along the axial direction, avoiding the additional bending moment caused by indirect connection in traditional structures, thereby significantly improving the overall structural strength and stability of the car.

[0018] In one embodiment, the car roof wheel is located above the car roof; Alternatively, the car roof wheel may be located within the area where the car roof is situated.

[0019] Understandably, by placing the car top wheel within the area of ​​the car top, a compact layout of the car top wheel can be achieved. This effectively saves vertical space at the top of the elevator car structure and reduces the height requirement for the top floor of the shaft, thus better meeting the installation restrictions of special buildings such as low-rise buildings.

[0020] This application also provides an elevator, including the elevator car structure described above.

[0021] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art: The elevator car structure and elevator claimed in this application utilize a straight beam that also functions as a car wall to directly support the car bottom platform, thereby eliminating the need for a traditional independent car frame structure. This achieves an integrated design for the elevator car structure. On one hand, the straight beam, while bearing the load, integrates the structural function of the side and center walls. This design not only eliminates the need for separate side and center wall components, but also effectively reduces the horizontal space occupation and number of components in the elevator car structure, thus reducing the vertical and horizontal space occupation and effectively improving the utilization rate of the shaft space. On the other hand, the simplified structure reduces the number of components and assembly complexity, making the installation process more convenient and shortening the installation cycle.

The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0032] like Figures 1 to 5As shown, an embodiment of this application provides an elevator car structure 100, including a car 10, multiple straight beams 20, a rear side wall 12, and a front side wall 13. The car 10 includes a car bottom platform 11. The multiple straight beams 20 are disposed on two opposite sides of the car bottom platform 11 and are respectively connected to the car bottom platform 11. At least a portion of each straight beam 20 constitutes part of the car wall of the car 10. The rear side wall 12 and the front side wall 13 are disposed on both sides of each straight beam 20 and are respectively connected to the corresponding straight beam 20 and the car bottom platform 11. The rear side wall 12, the straight beams 20, and the front side wall 13 together constitute the car side wall of the car 10. In other words, this application uses a straight beam 20 that also functions as a car wall to directly support the car bottom platform 11, thereby eliminating the traditional independent car frame structure and achieving an integrated design of the elevator car structure 100. On the one hand, while bearing the load-bearing function, the straight beam 20 integrates the structural function of the side and middle walls. This design not only eliminates the need for independent side and middle wall components, but also effectively reduces the space occupied by the elevator car structure 100 in the horizontal direction and the number of components, thereby reducing the space occupied by the elevator car structure 100 in the vertical and horizontal directions and effectively improving the utilization rate of the shaft space. On the other hand, the simplification of the structure reduces the number of components and the complexity of assembly, making the installation process more convenient and shortening the installation cycle.

[0033] like Figures 2 to 5 As shown, in one embodiment, the car floor platform 11 includes a car floor plate 111, a car floor frame 112, multiple load-bearing beams 113, and multiple reinforcing ribs 114. The multiple load-bearing beams 113 are mounted on the car floor plate 111, and the multiple reinforcing ribs 114 are located on the side of the multiple load-bearing beams 113 away from the car floor plate 111 and mounted on the car floor frame 112. Each load-bearing beam 113 is connected to multiple reinforcing ribs 114, and each reinforcing rib 114 is connected to multiple load-bearing beams 113. That is, this embodiment arranges the reinforcing ribs 114 and the load-bearing beams 113 in an alternating manner, forming a stable mesh support structure under the car floor platform 11. This design can effectively distribute and disperse local loads, significantly improving the bending and deformation resistance of the car floor platform 11, thereby enhancing its overall structural strength and rigidity.

[0034] Specifically, such as Figures 3 to 5 As shown, the car bottom frame 112 is located on the periphery of the car bottom plate 111 and connected to the car bottom plate 111. Specifically, the car bottom frame 112 and the car bottom plate 111 can be connected by welding. The two sides of the load-bearing beam 113 are bent and each forms a connecting plate portion 1131. The two connecting plate portions 1131 are attached to the car bottom plate 111 and connected to the car bottom plate 111. The two ends of the reinforcing rib 114 are both housed in the car bottom frame 112 and connected to the car bottom frame 112.

[0035] Here, the reinforcing rib 114 is semi-closed. It should be noted that the semi-closed reinforcing rib 114 mentioned above specifically means that the cross-sectional shape of the reinforcing rib 114 is not a completely closed shape, but can be U-shaped.

[0036] like Figure 1 , Figure 2 As shown, in one embodiment, the car 10 also includes a car roof 14, which is disposed between multiple straight beams 20 and connected to each straight beam 20 respectively. That is, this embodiment serves as the main load-bearing component, with its two ends directly connected to the car roof 14 and the car bottom platform 11. This constructs a complete force transmission frame, which enables the load to be efficiently transmitted along the axial direction, avoiding the additional bending moment caused by indirect connections in traditional structures, thereby significantly improving the overall structural strength and stability of the car 10.

[0037] like Figure 1 , Figure 2 As shown, there are two straight beams 20, symmetrically arranged on both sides of the car bottom platform 11. Of course, in other embodiments, there may be four or even more straight beams 20, which will not be elaborated here. The lower end of the straight beam 20 is directly connected to the car bottom platform 11, eliminating the car bottom bracket structure in the prior art and merging the car bottom platform 11 and the car bottom bracket. This results in the car bottom platform 11 occupying less height space, significantly reducing the required depth of the shaft pit.

[0038] Here, the straight beam 20 is configured as a bent plate. The two sides of the straight beam 20 are bent in the direction away from the rear side wall 12 and the front side wall 13, respectively, to form a first bent part 21 and a second bent part 22. The first bent part 21 is close to and connected to the rear side wall 12, and the second bent part 22 is close to and connected to the front side wall 13. Specifically, a bolt and nut assembly can be used to realize the connection between the first bent part 21 and the rear side wall 12, and the second bent part 22 and the front side wall 13, so as to facilitate the connection between the straight beam 20 and the rear side wall 12 and the rear side wall 13 respectively.

[0039] like Figure 3 As shown, the lower end of the straight beam 20 extends to a position flush with the car bottom platform 11, and the extension wall 23 of the straight beam 20 abuts against the outer side of the car bottom platform 11 and is connected to the car bottom platform 11. Specifically, a bolt and nut assembly can also be used to achieve the connection and fixation between the extension wall 23 and the car bottom frame 112 on the car bottom platform 11.

[0040] Among them, multiple straight beams 20 are connected by an upper beam 30, and a car top wheel 40 is provided on the upper beam 30, so that the elevator car structure 100 can use the car top wheel 40 to drive the car 10 to rise and fall.

[0041] Here, the car top wheel 40 is located above the car top 14. Of course, in other embodiments, the car top wheel 40 can also be located within the area where the car top 14 is located. Specifically, the car top wheel 40 can pass through the car top 14 and partially extend into the car interior of the car 10. This allows for a compact layout of the car top wheel 40, effectively saving vertical space at the top of the elevator car structure 100 and reducing the height requirement for the top floor of the shaft, thereby better meeting the installation restrictions of special buildings such as low-rise buildings.

[0042] like Figure 3 , Figure 4 As shown, in one embodiment, the straight beam 20 and the car bottom platform 11 are jointly connected to a safety clamp 50. The safety clamp 50 is assembled to the extension wall 23 by fasteners (not shown), and the fasteners pass through the side of the extension wall 23 and the car bottom platform 11 in sequence. That is to say, in this embodiment, the elevator car structure 100 uses the straight beam 20 and the car bottom platform 11 to jointly support the safety clamp 50. This achieves a high-strength integrated load-bearing mechanism for the safety clamp 50, which can effectively disperse and support the huge force generated by the safety clamp 50 during the braking process through the stable frame jointly constructed by the straight beam 20 and the car bottom platform 11. This significantly improves the installation strength of the safety clamp 50 and ensures that it can reliably meet the stringent requirements of high-load braking.

[0043] Here, the part of the straight beam 20 that abuts against the car bottom platform 11 has a common connection hole (not shown in the figure) with the car bottom platform 11, and the safety clamp 50 can be installed onto the connection hole by fasteners; wherein, the fasteners can be bolts, pins, etc.

[0044] like Figures 1 to 4 As shown, in one embodiment, the elevator car structure 100 further includes a guide shoe 60; the guide shoe 60 is located below the safety clamp 50 and is mounted on the bottom surface of the car bottom platform 11.

[0045] Specifically, such as Figure 4 As shown, the guide shoe 60 is assembled to the bottom surface of the car platform 11 via a guide shoe seat 61. The guide shoe seat 61 has a central reinforcing rib 611, and the car platform 11 is provided with a support rib 110 positioned directly above the central reinforcing rib 611 to support the guide shoe seat 61. In other words, the car platform 11 is structurally reinforced with the support rib 110 at the location supporting the guide shoe 60 to meet the usage requirements of the car platform 11 in supporting the guide shoe 60.

[0046] like Figure 2 , Figure 5 As shown, in one embodiment, the elevator car structure 100 further includes a buffer plate 70; the buffer plate 70 is disposed at the center of the car bottom platform 11 and connected to the reinforcing rib 114.

[0047] Specifically, such as Figure 5 As shown, the buffer plate 70 is attached to the bottom surface of the reinforcing rib 114; and a buffer plate bracket 115 is connected between the side walls 1141 of the two reinforcing ribs 114, the buffer plate bracket 115 connects to and supports the buffer plate 70.

[0048] In summary, the elevator car structure 100 of this application innovatively adopts a straight beam 20 that also functions as a car wall, directly connecting the car bottom platform 11 and the car top 14 to form a highly integrated load-bearing frame. This design achieves structural lightweighting by simplifying components, resulting in superior overall strength and rigidity, while also reducing system counterweight requirements, thus effectively controlling costs. Furthermore, this integrated elevator car structure 100 significantly reduces unnecessary vertical and horizontal space occupation by the car 10, allowing for the accommodation of a larger, higher-capacity car 10 within a given shaft cross-section, greatly improving shaft space utilization and transportation efficiency.

[0049] In addition, this application also provides an elevator, including the elevator car structure 100 described above.

[0050] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0051] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Any appropriate changes and variations made to the above embodiments within the scope of the essential spirit of the present utility model shall fall within the scope of protection claimed by the present utility model.
