Description

Technical Field

[0001] The invention relates to the technical field of lifting platforms, and in particular to a micro mobile lifting platform device. Background Art

[0002] Operators face many challenges in disassembling, repairing and installing large machinery or electrical components in a small space in a cigarette factory due to the lack of dedicated tooling equipment. Although commonly used hydraulic or screw jacks can provide sufficient support, their fixed design makes it difficult to move them during work, greatly limiting the flexibility and efficiency of the operation. On the other hand, although general-purpose lifting platforms are suitable for high-altitude operations, their large size and complex operation make them impractical for use in small spaces. Therefore, operators often have to use local materials and simple tools such as stools or wooden boards as temporary support platforms.

[0003] However, these temporary support platforms have many safety hazards. First, they lack the necessary anti-slip devices, which can easily cause operators to slip or fall during operations, causing personal injury. Secondly, these platforms often require the cooperation of multiple people to fix them, which not only increases the labor cost of the operation, but also easily causes the platform to shake or tip over due to improper cooperation, further exacerbating the safety risks. Therefore, in response to the special needs of operations in narrow spaces in cigarette factories, there is an urgent need for a miniature movable lifting platform that can be flexibly operated in a small space and has anti-slip and anti-tipping functions to ensure the safety of operators and equipment and improve work efficiency and quality.

[0032] The present invention provides a technical solution:

[0033] See also Figures 1 to 4 A micro mobile lifting platform device includes a workbench 1, a lifting module 2 is arranged at the bottom of the workbench 1, a supporting module 3 is arranged at the bottom of the lifting module 2, and a moving walking module 4 is arranged at the bottom of the supporting module 3. The height adjustment is achieved through the lifting module 2 under the workbench 1, the supporting module 3 under the lifting module 2 provides a stable support, and the moving walking module 4 under the supporting module 3 gives the device mobility. This layered design ensures both the flexibility of operation and the stability and safety of the structure, which perfectly meets the special needs of narrow space operations in cigarette factories.

[0034] Furthermore, the workbench 1 is made of stainless steel, wherein the bottom of the workbench 1 adopts a hollow design. The workbench 1 is made of stainless steel and has a hollow design at the bottom, which not only improves the corrosion resistance and strength of the device and reduces the overall weight, but also ensures the solidity of the structure. At the same time, it is conducive to air circulation, prevents overheating when used in a small space, and ensures the safety and comfort of the operating environment.

[0035] Furthermore, the lifting module 2 includes an upper left connecting rod 21 and an upper right connecting rod 22 rotatably connected to the bottom of the workbench 1. The upper left connecting rod 21 and the upper right connecting rod 22 rotatably connected to the bottom of the workbench 1 in the lifting module 2 form a stable quadrilateral support structure to provide necessary rigidity and stability for the lifting process, and ensure flexibility and safety when working in a narrow space; the lower end of the upper left connecting rod 21 is rotatably connected with a left threaded sleeve 23, and the left threaded sleeve 23 cooperates with the bidirectional screw 27 to realize the smooth lifting function of the lifting module 2, while maintaining the flexibility of the structure to adapt to the working requirements in a narrow space; the lower end of the upper right connecting rod 22 is rotatably connected with a right threaded sleeve 25, and the right threaded sleeve 25 is symmetrically designed with the left threaded sleeve 23, and cooperates with the bidirectional screw 27 to achieve smooth lifting, thereby enhancing the stability and flexibility of the lifting module 2 and adapting to the working requirements in a narrow space.

[0036] Furthermore, the outer side of the left threaded sleeve 23 is rotatably connected to the left lower connecting rod 24, which enhances the stability of the lifting module 2, and together with the right lower connecting rod 26, supports the supporting module 3 to ensure a smooth lifting process; the outer side of the right threaded sleeve 25 is rotatably connected to the right lower connecting rod 26, and the right lower connecting rod 26 and the left lower connecting rod 24 are symmetrically distributed, and jointly support the lifting module 2 and the workbench 1 to enhance structural stability; the left threaded sleeve 23 and the left lower connecting rod 24 and the right threaded sleeve 25 and the right lower connecting rod 26 are both rotatably connected by pins, and the left threaded sleeve 23 and the left lower connecting rod 24, as well as the right threaded sleeve 25 and the right lower connecting rod 26 are rotatably connected by pins, ensuring a flexible and stable rotation relationship between the connecting rods, providing structural guarantee for the smooth lifting of the lifting module 2, and enhancing the operating flexibility and reliability of the device in a small space.

[0037] Furthermore, the internal threads of the left threaded sleeve 23 and the right threaded sleeve 25 are connected with a bidirectional screw 27, and the bidirectional screw 27 passes through the left threaded sleeve 23 and the right threaded sleeve 25. The bidirectional screw 27 connected by the internal threads of the left threaded sleeve 23 and the right threaded sleeve 25 rotates to drive the left threaded sleeve 23 and the right threaded sleeve 25 to move toward or away from each other, thereby realizing the smooth lifting function of the lifting module 2. This design simplifies the lifting mechanism, improves the lifting efficiency and stability, and is particularly suitable for precise operation requirements in narrow spaces.

[0038] Furthermore, the left threaded sleeve 23 and the right threaded sleeve 25 are both provided with threads inside, and they are respectively matched with the opposite threads on the left and right ends of a bidirectional screw 27. The left threaded sleeve 23 and the right threaded sleeve 25 are respectively located on the opposite threads on the left and right ends of the bidirectional screw 27. With this design, when the bidirectional screw 27 rotates, it can simultaneously drive the left threaded sleeve 23 and the right threaded sleeve 25 to move toward or away from each other, thereby realizing the smooth lifting and lowering of the lifting module 2. This lifting method with compact structure and high transmission efficiency is particularly suitable for working needs in narrow spaces.

[0039] Furthermore, the support module 3 includes a support shaft 31 rotatably connected to the lower ends of the left lower connecting rod 24 and the right lower connecting rod 26, and the outer side of the support shaft 31 is rotatably connected to a support plate 32. The left lower connecting rod 24 and the right lower connecting rod 26 are connected by the support shaft 31, and the support plate 32 is rotatably connected to the outer side thereof. This design not only enhances the supporting stability of the device, but also enables the support plate 32 to flexibly adjust the angle according to the working requirements, thereby providing a stable supporting surface for the workbench 1, effectively preventing shaking during the lifting process, and ensuring the safety and stability of the operation.

[0040] Furthermore, the overall shape of the support plate 32 is "U-shaped". Through this "U-shaped" design of the support plate 32, this structure enhances the support stability and at the same time facilitates the flexible adjustment of the support angle according to the operation requirements in a narrow space, ensuring that the workbench 1 can obtain stable support at different heights and inclination angles, improving the safety and reliability of the operation.

[0041] Furthermore, the mobile walking module 4 includes a wheel transition plate 41 fixedly installed on the outside of the support plate 32. Wheel mounting plates 42 are fixedly installed at both ends of the wheel transition plate 41. Through the wheel transition plate 41 fixedly installed on the inside of the support plate 32 and the wheel mounting plates 42 fixed at both ends thereof, the flexible movement and stable support of the device are realized. This design not only enhances the structural strength of the mobile walking module 4 but also effectively prevents the device from tipping over during movement, ensuring the safety and convenience of the operator when operating in a narrow space.

[0042] Furthermore, the overall shape of the wheel transition plate 41 is "I-shaped", and the overall shape of the wheel mounting plate 42 is "L-shaped". Through the "I-shaped" design of the wheel transition plate 41 and the "L-shaped" design of the wheel mounting plate 42, by enhancing the structural stability and compactness, the anti-tipping ability and overall stability of the mobile walking module 4 are effectively improved. This design makes the device safer and more reliable when moving in a narrow space, while maintaining the compactness and flexibility of the device, meeting the requirements of operations in narrow spaces such as cigarette factories.

[0043] When in specific use, the working principle of the present invention is as follows:

[0044] Workbench and material selection:

[0045] The workbench 1 is not only made of stainless steel material that is corrosion-resistant, high-strength and easy to clean and maintain, but also has a specially designed hollow bottom. This design not only reduces the overall weight, ensures the firmness of the structure, but also greatly improves the air circulation. In an environment such as a cigarette factory where high temperature, humidity or smoke may exist, the hollow design effectively prevents overheating problems caused by a closed environment, ensuring the stable operation of the workbench 1 and the equipment above it. In addition, the selection of stainless steel material also avoids structural damage caused by long-term contact with wet or corrosive substances, extending the service life of the equipment.

[0046] Lifting module working principle:

[0047] The design of the lifting module 2 fully considers the flexibility of working in a small space. A stable quadrilateral support structure is formed by the rotational connection between the upper left connecting rod 21 and the upper right connecting rod 22 and the bottom of the workbench 1. The lower ends of the left threaded sleeve 23 corresponding to the upper left connecting rod 21 and the right threaded sleeve 25 corresponding to the upper right connecting rod 22 are connected, and the lifting function is realized through the threaded connection of the bidirectional screw 27. This design not only makes the lifting process smooth and controllable, but also realizes the synchronous or reverse movement of the upper left connecting rod 21 and the upper right connecting rod 22 through the rotation of the bidirectional screw 27, thereby accurately adjusting the height of the workbench 1. During the lifting process, the operator can rotate the bidirectional screw 27 manually or electrically to easily realize the lifting and lowering operation of the workbench 1, greatly improving the working efficiency.

[0048] Support module self-locking and quick-positioning mechanism:

[0049] The design of the support module 3 places special emphasis on support stability and quick locking functions. Through the rotational connection between the support shaft 31 and the lower left connecting rod 24 and the lower right connecting rod 26, the support plate 32 can flexibly adjust the angle to meet different operating requirements. When the lifting module 2 raises the workbench 1 to the required height, the self-locking mechanism on the support plate 32 can respond quickly and lock the position of the support plate 32 to prevent accidental descent due to external forces. This design not only ensures safety during the operation, but also reduces the operator's need to fix and monitor the platform, further improving operating efficiency.

[0050] Anti-tipping and anti-slip design of mobile walking module:

[0051] The design of the mobile walking module 4 fully considers the stability and safety of the equipment during movement. The combination of the "I"-shaped wheel transition plate 41 and the "L"-shaped wheel mounting plate 42 not only enhances the stability of the structure, but also effectively prevents the risk of tipping over during movement. At the same time, anti-skid wheels are used as walking wheels, which can maintain good grip even on slippery or uneven ground. This design ensures the stability and safety of the device during movement and provides a more reliable working environment for operators.

[0052] In summary, the present invention realizes a micro-mobile lifting platform device that is flexible to operate, smoothly lift, stably support, safely move and highly efficient in a small space in a cigarette factory by adopting a hollow workbench 1 designed with stainless steel, a stable lifting module 2, a quickly locked support module 3 and an anti-tipping and anti-slip moving walking module 4. This design not only solves the problem of the inconvenience of using traditional tooling equipment in a small space, but also greatly improves the operating efficiency and quality, and ensures the safety of operators and equipment.

[0053] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the present invention to solve basically the same technical problems and achieve basically the same technical effects are all included in the protection scope of the present invention.
