Description

Technical Field

[0001] This utility model relates to the field of elevator car technology, and in particular to a detachable energy-saving elevator car. Background Technology

[0002] Energy-efficient elevator cars significantly reduce energy consumption and improve energy efficiency through various technological means. Their core functions include: employing permanent magnet synchronous gearless traction technology, which reduces energy consumption compared to traditional traction machines; and using an energy feedback system to feed electrical energy generated during braking back to the power grid, achieving energy savings. Furthermore, the car's counterweight device balances the load, reducing motor power loss, while lightweight materials reduce weight while ensuring safety, further reducing energy consumption. The advantages of detachable assembly in energy-efficient elevator cars are mainly reflected in construction and maintenance: firstly, improved efficiency, as on-site assembly of prefabricated components significantly shortens the construction period, making it simpler and more efficient than traditional construction; secondly, environmental friendliness, reducing construction waste and on-site pollution, aligning with green building principles; and thirdly, flexibility, facilitating later maintenance or component replacement, such as allowing the car's interior decoration to be adjusted as needed, extending the equipment's lifespan. The combination of energy-saving design and detachable assembly optimizes the elevator's energy utilization and reduces overall life-cycle costs.

[0003] Existing detachable energy-saving elevator cars have shortcomings. First, their frame disassembly and assembly are not convenient enough, and their support reliability needs to be strengthened. Second, their bulky structure leads to high energy consumption in the drive system. In view of this, the inventors hope to optimize and improve existing detachable energy-saving elevator cars. Summary of the Invention

[0004] The purpose of this invention is to overcome the aforementioned problems in traditional technologies and provide a detachable energy-saving elevator car.

[0005] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution: A detachable energy-saving elevator car includes corner plate supports, anchors, I-beam support plates, fastening screws, horizontal car panels, and vertical car panels. Four corner plate supports are provided, each including a right-angle plate body. Each right-angle plate body has an outer limiting plate and an inner limiting plate at both ends. A clamping area is formed between the outer and inner limiting plates to cooperate with the I-beam support plate. The outer and inner limiting plates have symmetrically opened anchoring holes. An anchor for locking the I-beam support plate is installed in both anchoring holes. A horizontal car panel is installed inside the middle of the I-beam support plate via fastening screws. The vertical car panels are symmetrically installed between two opposite horizontal car panels.

[0006] Furthermore, in the aforementioned detachable energy-saving elevator car, the right-angle plate body, outer limiting plate, and inner limiting plate of the corner plate support are integrally cast structures.

[0007] Furthermore, in the aforementioned detachable energy-saving elevator car, the I-beam support plate has anchoring inner holes at its four corners to facilitate the installation of anchors, and the I-beam support plate has fastening through holes at its central connecting plate to facilitate the installation of fastening screws.

[0008] Furthermore, in the aforementioned detachable energy-saving elevator car, the horizontal panel includes a horizontal panel portion and several strip-shaped reinforcing portions located on its inner side. The length of the strip-shaped reinforcing portions on both sides is equal to the distance between the front and rear corner plate supports, and the strip-shaped reinforcing portion in the middle is provided with a fastening screw hole that cooperates with the fastening screw.

[0009] Furthermore, in the aforementioned detachable energy-saving elevator car, the horizontal plate portion of the horizontal panel abuts against the inner side of the inner limiting plate in the corner plate support, and the thickness of the strip reinforcement portion in the horizontal panel is equal to the thickness of the inner limiting plate.

[0010] Furthermore, in the aforementioned detachable energy-saving elevator car, the inner walls of both sides of the vertical car panel are fixed to the plate portion of the corner plate support member that is flush with the right-angle plate body by means of adhesive.

[0011] Furthermore, in the aforementioned detachable energy-saving elevator car, each component of the elevator car is made of high-strength steel.

[0012] The beneficial effects of this utility model are: 1. High Strength and Durability: All components are made of high-strength steel, ensuring the car as a whole possesses excellent load-bearing capacity and impact resistance. The one-piece cast structure of the corner plate supports completely eliminates the weak points of traditional welded structures, significantly improving the fatigue resistance of key connection parts. The equal thickness design of the strip reinforcements of the horizontal panels and the inner limit plates further optimizes load distribution, avoids local stress concentration, and extends service life.

[0013] 2. Rapid Assembly and Disassembly: The modular design concept runs through the entire car structure, significantly improving installation efficiency. Four identical corner plate supports are quickly locked to the I-beam support plates via anchors, forming the basic frame; the horizontal car panels are fixed by fastening bolts through pre-drilled fastening holes; finally, the vertical car panels are installed using adhesive. This systematic assembly process can significantly shorten the traditional car installation time. Equally important, this design also facilitates later car modifications or component replacements. For example, during elevator modernization, the car panels can be updated separately without replacing the support structure, significantly reducing modification costs. The dimensional control in the design is extremely precise. For example, the precise fit between the clamping area formed by the outer and inner limit plates and the I-beam support plates ensures automatic alignment during the assembly of all components. The length of the strip reinforcements on both sides of the horizontal car panels is strictly equal to the spacing between the front and rear corner plate supports, eliminating cumulative errors and ensuring assembly quality.

[0014] 3. Energy-saving and environmentally friendly characteristics: The optimization of materials and structure in this car has brought about significant energy-saving effects. On the one hand, the weight reduction of the structure reduces the energy consumption of the drive system; on the other hand, the precise fit of all connecting parts reduces energy loss during operation. At the same time, the detachable design allows the car to achieve a material recycling rate of over 90% when it is scrapped, which is in line with the concept of green manufacturing.

[0015] 4. Enhanced Safety Performance: Although this design emphasizes detachability, its safety performance is not only not reduced but actually enhanced. The connection between the corner plate support and the I-beam support plate through anchors has extremely high shear resistance; while the use of high-strength steel ensures that the car maintains structural integrity even in extreme situations, meeting the safety requirement of "no deformation in emergency situations".

[0016] 5. Ease of Maintenance: The ability to disassemble each component independently makes maintenance more convenient and efficient. For example, when inspecting or replacing a horizontal panel, simply loosen the corresponding fastening screws to remove the target panel without affecting other components. This design greatly facilitates routine inspections, such as measuring car wall thickness and assessing the condition of fire-retardant coatings, which can be quickly completed in localized areas.

[0017] 6. Adaptability and Expandability: The basic frame design of this car is highly adaptable, allowing for adjustments to the length of the I-beam support plates and the dimensions of the horizontal panels to meet different car specifications. Simultaneously, this structure facilitates the integration of various elevator subsystems, such as reserving space within the strip reinforcement sections of the horizontal panels to install safety devices, lighting systems, or monitoring equipment. The interior of the car can also be flexibly finished with different materials to match the architectural style, such as PVC marble-patterned flooring or mirrored stainless steel, achieving a balance between functionality and aesthetics.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the above advantages at the same time. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-6As shown, this embodiment is a detachable energy-saving elevator car. The elevator car includes corner plate supports 1, anchors 2, I-beam support plates 3, fastening screws 4, horizontal car panels 5, and vertical car panels 6. There are four corner plate supports 1. Each corner plate support 1 includes a right-angle plate body 101. Each end of the right-angle plate body 101 is provided with an outer limiting plate 102 and an inner limiting plate 103. A clamping area 104 that cooperates with the I-beam support plate 3 is formed between the outer limiting plate 102 and the inner limiting plate 103. The outer limiting plate 102 and the inner limiting plate 103 are symmetrically provided with anchoring outer holes 105. Anchors 2 for locking the I-beam support plate 3 are installed in the two anchoring outer holes 105. The horizontal car panel 5 located inside the middle of the I-beam support plate 3 is installed through the fastening screws 4. The vertical car panels 6 are symmetrically installed between two opposite horizontal car panels 5.

[0023] In this embodiment, the right-angle plate body 101, outer limiting plate 102, and inner limiting plate 103 in the corner plate support 1 are integrally cast structures.

[0024] In this embodiment, the I-beam support plate 3 has anchoring inner holes 301 at the four corners to facilitate the installation of anchors 2, and the I-beam support plate 3 has fastening through holes 302 at the middle connecting plate to facilitate the installation of fastening screws 4.

[0025] In this embodiment, the horizontal panel 5 includes a horizontal panel portion 501 and a plurality of strip-shaped reinforcing portions 502 disposed on its inner side. The length of the strip-shaped reinforcing portions 502 located on both sides is equal to the distance between the front and rear corner plate support members 1. The strip-shaped reinforcing portion 502 located in the middle is provided with a fastening screw hole 503 that cooperates with the fastening screw 4.

[0026] In this embodiment, the horizontal plate portion 501 in the horizontal panel 5 abuts against the inner side of the inner limiting plate 103 in the corner plate support member 1, and the thickness of the strip reinforcement portion 502 in the horizontal panel 5 is equal to the thickness of the inner limiting plate 103.

[0027] In this embodiment, the inner walls of both sides of the vertical panel 6 are fixed to the right-angle plate body 101 of the corner plate support member 1 by adhesive.

[0028] In this embodiment, all components of the elevator car are made of high-strength steel.

[0029] One specific application of this embodiment is: The assembly process begins with the accurate positioning of the four corner plate supports 1. These integrally cast components (including the right-angle plate body 101, the outer limiting plate 102, and the inner limiting plate 103) constitute the basic frame of the car. During installation, special positioning fixtures must be used to ensure that the spatial geometry of the four corner plate supports 1 fully conforms to the design dimensions. The accuracy of this step directly determines the assembly quality of all subsequent components. After positioning, the corner plate supports need to be temporarily fixed to prevent displacement, usually using lightweight clamps to temporarily fix them on the base plate. The orientation of the corner plate supports 1 must be correct, with the outer limiting plate 102 of each component facing outwards from the car and the inner limiting plate 103 facing inwards, to ensure that the subsequent I-beam support plate 3 can be smoothly inserted into the clamping area 104.

[0030] The I-beam support plate 3, as a key component connecting the corner plate support 1, requires precise step-by-step installation. First, align the end of the I-beam support plate 3 with the clamping area 104 (the space formed by the outer limiting plate 102 and the inner limiting plate 103) and gently insert it until fully in place. At this point, the anchoring inner hole 301 at the corner of the I-beam support plate 3 should be perfectly aligned with the anchoring outer hole 105 on the corner plate support 1. Then, insert the anchor 2 (usually a high-strength pin or bolt) and secure it with the locking device, forming a rigid connection between the I-beam support plate 3 and the corner plate support 1. This connection must be able to withstand various dynamic loads during elevator operation. The inspection standard is that there is no visible shaking after the anchor 2 is installed, and the sound when tapping the connection is crisp and without any extraneous noise. After all four corner I-beam support plates 3 are installed, the basic cubic frame of the car is formed. At this point, the overall dimensions and verticality of the frame should be re-measured to confirm that it meets the design requirements before proceeding to the next step.

[0031] The horizontal panel 5 is connected to the I-beam support plate 3 via the fastening screw holes 503 on its central strip-shaped reinforcing part 502. Before installation, ensure that the contact surfaces of the horizontal panel 501 and the inner limiting plate 103 are clean and free of foreign objects to ensure a complete fit. Raise the horizontal panel 5 to the appropriate position, aligning its strip-shaped reinforcing part 502 with the fastening through hole 302 in the middle of the I-beam support plate 3. Then insert the fastening screw 4 and tighten it gradually and evenly. The tightening process should be controlled using a torque wrench, and tightened in two stages according to the designed torque value (first pre-tighten to 50% torque, then fully tighten) to ensure a reliable connection and prevent excessive internal stress.

[0032] The length of the strip-shaped reinforcing parts 502 located on both sides is strictly equal to the spacing between the front and rear corner plate supports 1. During installation, they should be able to be naturally positioned without forced compression; otherwise, it indicates that there was a deviation in the previous frame assembly and adjustments are needed. After all the horizontal panels 5 are installed, the floor and roof structure of the car is formed, and at this point, the main load-bearing system of the car is complete.

[0033] The vertical panel 6 is fixed to the assembled frame structure with adhesive. Before installation, the bonding surface of the right-angle plate body 101 and the inner walls of both sides of the vertical panel 6 must be thoroughly cleaned to remove oil, dust, and oxides. If necessary, a special cleaning agent should be used. Then, high-strength structural adhesive is evenly applied to the designated area of ​​the right-angle plate body 101 (the adhesive layer thickness is recommended to be controlled between 0.3 and 0.5 mm). After precisely positioning the vertical panel 6, it is pressed into the bonding position, applying appropriate pressure and holding until the adhesive has initially cured. To ensure bonding quality, temporary clamps can be used to fix the vertical panel 6, which can be removed after the adhesive has fully cured. After installation, the vertical panel 6 should be completely flush with the right-angle plate body 101 in the corner plate support 1, forming a smooth and continuous inner surface of the car. Any protrusions or depressions indicate installation errors that require adjustment. After this step, the complete box-shaped structure of the car is formed.

[0034] After all structural assembly is completed, a systematic inspection is required. This includes: rechecking the tightness of all mechanical connections (anchors 2, fastening bolts 4) to ensure there is no looseness; checking the integrity of adhesive connections to ensure there is no cracking or delamination; verifying the overall dimensions of the car, especially ensuring the diagonal length difference is within the allowable range (usually ≤3mm); and checking the flatness of the car walls, using a ruler to check that gaps do not exceed 1mm / meter. During the commissioning phase, dynamic testing is also required to simulate the structural performance under full load conditions, confirming there are no abnormal deformations or unusual noises.

[0035] Only after all inspections have passed can interior decoration (such as laying PVC marble-patterned flooring or mirrored stainless steel ceiling) and installation of functional components (such as lighting, ventilation, monitoring, etc.) be carried out.

[0036] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to specific implementation methods. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
