[0001] This utility model belongs to the field of electric wheel assembly technology, specifically relating to a lifting platform device. Background Technology

[0002] In the field of electric wheel assembly, especially when assembling large electric wheels like the FJXBL1200 model, specialized assembly auxiliary devices are often required to ensure smooth operation. Currently, existing assembly equipment on the market generally suffers from insufficient adaptability, making it difficult to fully match the size specifications of the FJXBL1200 electric wheel. This results in a lack of precise and stable support for workers during assembly, affecting not only assembly efficiency but also potentially increasing operational safety risks. Furthermore, traditional assembly equipment often has a fixed structure and cannot flexibly adjust its dimensions according to the actual assembly requirements of the electric wheel, resulting in poor versatility and limiting its application in the assembly of large electric wheels. Utility Model Content

[0003] The purpose of this utility model is to provide a lifting platform device to solve the technical defects of existing assembly equipment, which on the one hand cannot provide workers with precise and stable working support, and on the other hand, because most assembly equipment has a fixed structure, it cannot flexibly adjust its own size according to the actual assembly needs of electric wheels, resulting in poor versatility and limiting its application in the assembly of large electric wheels.

[0004] The technical solution adopted in this utility model is as follows: A lifting platform device, comprising: Two support frames positioned opposite each other; Support plates are fixed to the top of the two support frames; The enclosure component is connected to the edge of the support plate; An adjusting component, fixed on the support frame, has its top connected to the bottom of the support plate and is used to drive the support plate to move up and down. A movable component is provided at the bottom of the support frame to move the two support frames away from or closer to each other; The climbing component is installed on the outside of one of the support frames and is axially parallel to the support frame. The control unit is electrically connected to the regulating element.

[0005] Furthermore, the two support frames have identical structures, and the adjusting components include: A lifting unit is symmetrically arranged at the middle of the bottom end of the support frame, and the driving end of the lifting unit is connected to the bottom of the support plate; Guide rods are located at both ends of the bottom of the support frame, and positioning rods are slidably connected in the guide rods. The top of the positioning rods is connected to the bottom of the support plate. A positioning hole is formed on the guide rod and is axially perpendicular to the guide rod. A positioning insert rod is inserted into the positioning hole. In this process, after the control unit controls the lifting unit to drive the support plate to move up and down, the positioning rod is inserted into the positioning hole to position the height of the support plate.

[0006] Furthermore, the bottom of the support plate is provided with a fisheye connector pin seat, and the bottom end of the support frame is provided with a hinge pin seat; One end of the lifting unit is connected to the fisheye connector pin seat, and the other end is connected to the hinge pin seat.

[0007] Furthermore, the lifting unit is a hydraulic cylinder.

[0008] Furthermore, the movable component is symmetrically arranged in the middle of the bottom of the support frame, and a support threaded column is connected to the top of the movable component. The support threaded column extends to the top of the bottom of the support frame and is provided with a handwheel. When the handwheel is rotated, the moving part is moved up and down.

[0009] Furthermore, the movable component is a caster.

[0010] Furthermore, one of the support frames and support plates is equipped with quick clamps, and the other support frame and support plate is equipped with countersunk screws; When two opposing support frames move closer or further apart via a moving part, the quick clamp is adapted to the countersunk screw to allow the two support frames or the two support plates to merge or separate.

[0011] Furthermore, a passage is provided on the enclosure near the climbing component, and the passage corresponds to the climbing component.

[0013] Furthermore, the two support plates form an octagonal structure.

[0014] Compared with the prior art, the present invention has the following beneficial effects: This lifting platform device, by incorporating a movable component at the bottom of the support frame, allows for the adjustment of the displacement of two opposing support frames, moving them closer or further apart. This enables flexible changes to the overall dimensions of the device. Addressing the issue of the large overall size of the FJXBL1200 electric wheel and the insufficient compatibility of existing equipment, the device precisely adjusts the support frame spacing to perfectly match the assembly dimensions of this electric wheel model. This provides a stable and well-fitting support foundation for assembly operations, effectively solving the problems of low assembly efficiency and poor operational stability caused by mismatches in traditional equipment. The adaptability and specialization are significantly improved. Furthermore, the movable component not only enables flexible adjustment of the device's size but also provides convenient mobility.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0018] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0019] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0020] To address the technical deficiencies mentioned in the background section, the present invention will be further described in detail below with reference to the accompanying drawings: like Figures 1-3 As shown, a lifting platform device includes two support frames 1 arranged opposite each other, forming a ring structure between the two support frames 1; a support plate, which includes a first support plate 2 and a second support plate 5, the first support plate 2 being welded to the top of one of the support frames 1, the second support plate 5 being welded to the top of the other support frame 1, and the first support plate 2 and the second support plate 5 forming an octagonal structure.

[0021] The enclosure component is connected to the edges of the first support plate 2 and the second support plate 5, and is axially perpendicular to the first support plate 2 and the second support plate 5; the adjusting component is fixed on the two support frames 1, and its top is connected to the bottom of the first support plate 2 and the second support plate 5, for driving the first support plate 2 and the second support plate 5 to move up and down; the moving component is set at the bottom of the support frame 1 to drive the two support frames 1 to move away from or closer to each other; the climbing component is set on the outside of one of the support frames 1 and is axially parallel to the support frame 1; the control body is electrically connected to the adjusting component.

[0022] When in use, the lifting platform device can drive the two opposing support frames 1 to move away from or towards each other by using the movable parts set at the bottom of the support frame 1, thereby flexibly changing the overall size and specifications of the lifting platform device. In addition, in response to the problem that the FJXBL1200 model electric wheel has a large overall size and insufficient compatibility with existing equipment, the distance between the two support frames 1 is precisely adjusted to fully match the assembly size requirements of this model of electric wheel, providing a stable and close-fitting support foundation for assembly operations. This effectively solves the problems of low assembly efficiency and poor operational stability caused by adaptation deviations in traditional equipment, and significantly improves adaptability and specialization.

[0023] During the assembly of the FJXBL1200 electric wheel model, the movable parts not only enable flexible adjustment of the size of the lifting platform device, but also improve the ease of movement of the lifting platform device. Compared with traditional fixed-structure assembly equipment, the working position can be quickly adjusted according to the needs of the assembly process through the movable parts, adapting to different assembly station layouts. At the same time, due to the compact overall structural design of the lifting platform device, it occupies less space and can better adapt to assembly scenarios with limited space, greatly improving space utilization and breaking the limitations of traditional equipment in terms of mobility and space adaptability.

[0024] Furthermore, the barriers at the edges of the first support plate 2 and the second support plate 5 can protect the electric wheel components, assembly tools, or assembly workers placed on the first support plate 2 and the second support plate 5, preventing safety hazards caused by components slipping or tools falling during operation. Combined with the stable support structure, this further reduces the operational safety risks during the assembly of large electric wheels. On the other hand, the adjusting components are electrically connected to the control body, allowing workers to precisely drive the first support plate 2 and the second support plate 5 to move up and down without manual operation, reducing labor intensity. At the same time, with the climbing components set on the outside, workers can easily climb onto the first support plate 2 and the second support plate 5 to perform high-altitude assembly operations, making the operation process more efficient and safer.

[0025] In this scheme, the two support frames 1 have the same structure. The adjusting components include a lifting unit, which is symmetrically arranged at the middle of the bottom end of the support frame 1. The driving end of the lifting unit is connected to the bottom of the first support plate 2 and the second support plate 5. Guide rods are located at both ends of the bottom end of the support frame 1. Positioning rods are slidably connected in the guide rods. The top of the positioning rods is connected to the bottom of the support plate. Positioning holes are opened on the guide rods and are axially perpendicular to the guide rods. Positioning rods 21 are inserted and pulled into the positioning holes. After the control body controls the lifting unit to drive the first support plate 2 and the second support plate 5 to move up and down, the positioning rods 21 are inserted into the positioning holes to position the adjusted height of the first support plate 2 and the second support plate 5.

[0026] Because the lifting units in the adjusting components are symmetrically arranged at the bottom center of the support frame 1, and the drive end is connected to the bottom of the first support plate 2 and the second support plate 5, it ensures that the first support plate 2 and the second support plate 5 are subjected to uniform force during vertical displacement, avoiding problems such as tilting and swaying. This achieves precise and stable height adjustment, providing stable height adaptation for the assembly of large products such as the FJXBL1200 electric wheels, effectively solving the problem of unstable lifting of traditional assembly equipment affecting assembly accuracy. At the same time, the electrical control of the lifting unit by the control unit allows workers to precisely adjust the height of the first support plate 2 and the second support plate 5 according to assembly requirements, making operation convenient and adjustment more precise, further improving the accuracy of assembly operations.

[0027] The sliding connection structure between the guide rod and the positioning rod 21 provides stable guidance for the vertical displacement of the first support plate 2 and the second support plate 5, preventing deviation during displacement and further enhancing the stability of the lifting adjustment. The plug-in / plug-out design of the positioning hole and the positioning rod 21 allows the height of the first support plate 2 and the second support plate 5 to be fixed and locked after the lifting unit has completed height adjustment, forming a protective structure. This effectively prevents the first support plate 2 and the second support plate 5 from accidentally falling due to sudden situations such as lifting unit malfunction, significantly improving the structural reliability and operational safety of the device during assembly and reducing the safety risks during the assembly of large electric wheels.

[0028] Since the two support frames 1 have the same structure and the lifting unit, guide rod and other adjustment components are symmetrically arranged, it not only facilitates the standardized production of parts, reduces the difficulty of research and development and manufacturing of parts of different specifications, and lowers the production and manufacturing cost; at the same time, the symmetrical structure makes the installation, debugging and subsequent maintenance of the device simpler, the parts have strong versatility, and if the parts are damaged in the future, the replacement and repair will be more efficient, further reducing the total life cycle cost of the equipment.

[0029] Furthermore, the bottom of the first support plate 2 and the second support plate 5 is provided with a fisheye connector pin seat 7, which is fixed by a first internal hexagonal head screw 8. The bottom ends of the two support frames 1 are provided with hinge pin seats 10. One end of the lifting unit is connected to the fisheye connector pin seat 7, and the other end is connected to the hinge pin seat 10. A first shaft retaining ring 9 is installed on the end of the lifting unit connected to the fisheye connector pin seat 7.

[0030] Among them, the fisheye joint pin seat 7 at the bottom of the first support plate 2 and the second support plate 5 cooperates with the hinge pin seat 10 at the bottom of the support frame 1, providing a double hinge connection structure for the lifting unit; the fisheye joint can realize a certain angle of swing compensation, which can adapt to the small angle deviation between the first support plate 2 and the second support plate 5 and the corresponding support frame 1 due to assembly error or force deformation during the lifting process, avoid the lifting unit from bearing additional bending moment, ensure more stable and efficient power transmission, reduce component wear, and extend the service life of the lifting unit.

[0031] The fisheye connector pin seat 7 is fixed by the first internal hexagonal head screw 8. The screw connection has the advantages of convenient disassembly and strong fastening, which facilitates the disassembly and replacement of the pin seat or lifting unit during later maintenance. At the same time, the first shaft retaining ring 9 at the connection end between the lifting unit and the fisheye connector pin seat 7 can effectively limit the axial displacement of shaft components, prevent the lifting unit from loosening or falling off during repeated lifting and lowering, and further improve the reliability of the connection structure.

[0032] In this scheme, the lifting unit is a hydraulic cylinder 20. The hinge pin seat 10 at the end of the hydraulic cylinder 20 connected to the support frame 1 is fixed to the support frame 1 by a second internal hexagonal head screw 11. A second shaft retaining ring 18 and a first pin 19 are installed on the end of the hydraulic cylinder 20 connected to the support frame 1. A second pin 22 is provided on the end of the hydraulic cylinder 20 connected to the fisheye joint pin seat 7 on the support frame 1.

[0033] The hydraulic cylinder 20 is connected to an external hydraulic power station. Using the hydraulic cylinder 20 as the lifting unit, hydraulic transmission has significant advantages such as large output torque and strong power, which can easily support products with large overall size and heavy weight, such as the FJXBL1200 electric wheel, providing sufficient and stable support for its assembly operation. Compared with traditional electric lifting methods, the hydraulically driven cylinder 20 operates more smoothly under heavy load conditions, avoiding problems such as lifting jamming and insufficient power caused by excessive load. It effectively ensures the stable lifting and lowering of the support plate during the assembly of large electric wheels, meeting the core requirements of heavy-duty assembly scenarios.

[0034] The hydraulic cylinder 20 is used in conjunction with an external hydraulic power station. The hydraulic power station can precisely regulate the pressure and flow of the hydraulic oil, thereby achieving precise control over the extension and retraction speed and stroke of the hydraulic cylinder 20. Combined with the electrical control of the main control unit, workers can precisely adjust the lifting positions of the first support plate 2 and the second support plate 5 according to the height requirements of different assembly processes of the FJXBL1200 electric wheel, ensuring the height accuracy of the assembly operation. This solves the problem of insufficient adjustment accuracy of traditional lifting equipment affecting the assembly quality, and further improves the assembly accuracy and work efficiency of large electric wheels.

[0035] In this design, the movable parts are symmetrically arranged at the middle of the bottom of the support frame 1. The top of the movable parts is connected to a support threaded post 12, which extends to the top of the bottom of the support frame 1 and is equipped with a handwheel 15. When the handwheel 15 is turned, the movable parts are moved up and down. The movable parts are casters 13, and a connecting plate 14 is installed on the casters 13. Hexagonal head bolts 16 are installed on the connecting plate 14, and a nameplate 17 is installed on the support frame 1.

[0036] The movable component uses casters 13, which are symmetrically arranged at the bottom center of the support frame 1. The casters 13 themselves have the characteristic of flexible movement, which can easily drive the entire device to change position according to the assembly station adjustment requirements of the FJXBL1200 electric wheels, solving the pain point of inconvenient movement of traditional large assembly equipment. At the same time, by rotating the handwheel 15 to drive the support threaded column 12 to move up and down, the casters 13 can be made to contact or detach from the ground.

[0037] When moving, the casters 13 are lowered to contact the ground, improving the flexibility of movement; during assembly, the casters 13 are raised so that the bottom ends of the two support frames 1 are directly supported on the ground. The threaded locking characteristics of the support threaded column 12 are used to achieve stable fixation of the device, avoiding displacement during operation, and balancing the convenience of movement and the stability of support.

[0038] like Figure 1 and Figure 3 As shown, one of the support frames 1 and the second support plate 5 are provided with quick clamps 4, and the other support frame 1 and the first support plate 2 are provided with countersunk screws 3; wherein, when the two opposing support frames 1 move closer or further apart through the moving parts, the quick clamps 4 and the countersunk screws 3 are adapted to make the two support frames 1 merge or separate, and the first support plate 2 and the second support plate 5 merge or separate.

[0039] In the above structure, the quick clamp 4 and the countersunk screw 3 are designed to be compatible, so that after the two support frames 1 and the corresponding support plates are adjusted by the moving parts, the quick clamp 4 can quickly engage the countersunk screw 3 to lock them, and the merging or separation can be fixed without complicated tools.

[0040] In this solution, a passage is provided on the enclosure near the climbing component, corresponding to the climbing component. The climbing component is a ladder, and the enclosure is a fence 6. The ladder provides workers with a stable and safe access to heights. With the corresponding passage on the fence 6, workers can directly climb the ladder to the first support plate 2 and the second support plate 5 without the need for external climbing equipment, greatly simplifying the passage process for high-altitude assembly operations. For high-altitude assembly processes of large products such as the FJXBL1200 electric wheel, it can quickly enable workers to travel back and forth between the ground and the working surface of the support plate, effectively improving the efficiency of high-altitude assembly operations and solving the problems of cumbersome and time-consuming operation of traditional climbing methods.

[0041] In this design, the first support plate 2 and the second support plate 5 are made of patterned steel, which can increase friction after the workers stand up and prevent the assembly workers from falling while working.

[0042] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
