[0050] As Figures 1 to 4 shown. This embodiment provides a maintenance platform, which includes a workbench 100 and an extension platform 200. Among them, the workbench 100 includes a first standing surface 110. The extension platform 200 is movably connected to the workbench 100 and is controlled to move. The extension platform 200 includes a second standing surface 210. The second standing surface 210 is parallel to the first standing surface 110, and the movement trajectory of the extension platform 200 is parallel to the first standing surface 110. Among them, the maintenance platform includes a normal state and an extended state. When the maintenance platform is in the normal state, the extension platform 200 is located inside the workbench 100. When the maintenance platform is in the extended state, the extension platform 200 is controlled to move outside the workbench 100, and the first standing surface 110 and the second standing surface 210 are combined into a working plane.

[0051] The overall structure of this maintenance platform consists of the workbench 100 and the extension platform 200. The workbench 100 is the core support structure of the platform, providing a basic standing surface and an operating area. The extension platform 200 is movably connected to the workbench 100 and can move under controlled conditions to realize the expansion and contraction of the working area. This design enables the maintenance platform to remain compact in the normal state, suitable for maintenance operations in narrow spaces, and can significantly increase the standing area in the extended state to meet the maintenance requirements of large equipment.

[0052] In this embodiment, through the combined design of the workbench 100 and the extension platform 200, the disadvantages of the existing maintenance platform with limited standing area and frequent movement of the maintenance personnel to move the platform are effectively solved, the flexible adjustment of the standing area is realized, and the controlled movement mechanism of the extension platform 200 ensures the stability and safety of the platform expansion, preventing accidental sliding or displacement during the work process.

[0053] Specifically, the workbench 100 is the main part of the maintenance platform, mainly including the first standing surface 110 and related support structures. The first standing surface 110 is the basic plane for maintenance personnel to operate, providing a stable standing area. The support structure of the workbench 100 can select a suitable support design according to specific application requirements, such as support columns and the adjustable-height lifting platform 130 described later.

[0054] Further, as Figure 4As shown in the figure. In some embodiments, the workbench 100 includes a base 120 and a lifting platform 130. The lifting platform 130 is disposed on the base 120. The side of the lifting platform 130 facing away from the base 120 is the first standing surface 110, and the lifting platform 130 is controllably telescopic to drive the movement of the first standing surface 110. The movement trajectory of the first standing surface 110 is perpendicular to the first standing surface 110. Further, the lifting platform 130 should include a plate member and a jacking mechanism. The fixed end of the jacking mechanism is installed on the base 120, and the movable end of the jacking mechanism is connected to one side of the plate member to drive the plate member to lift. The side of the plate member facing away from the jacking mechanism is the first standing surface 110.

[0055] The workbench 100 can be made of high-strength alloy steel or aluminum alloy to ensure sufficient load-bearing capacity and durability. In addition, the surface of the workbench 100 can be covered with anti-slip materials such as anti-slip rubber or textured coatings to improve the safety of maintenance personnel during work.

[0056] The workbench 100, as the basic support part of the maintenance platform, provides an initial working area and a foundation for the movement and fixation of the extension platform 200. Through a solid support design, the stability of the entire maintenance platform during use is ensured, avoiding tilting or shaking.

[0057] The extension platform 200 is connected to the workbench 100 through movable connectors and mainly includes a second standing surface 210. The movement trajectory of the extension platform 200 is parallel to the first standing surface 110. In this way, in the extended state, the second standing surface 210 can be seamlessly joined with the first standing surface 110 to form a continuous working plane, significantly increasing the standing area. The movement of the extension platform 200 can be achieved by electric drive or manual sliding. It should be noted that the second standing surface 210 on the extension platform 200 and the first standing surface 110 on the workbench 100 can be coplanar or parallel and offset. Taking the coplanarity of the second standing surface 210 and the first standing surface 110 as an example, a receiving space needs to be constructed inside the workbench 100, and a through groove communicating with the receiving space needs to be opened on the side of the workbench 100, and the extension platform 200 is inserted into the through groove to facilitate the pulling out or storage of the extension platform 200.

[0058] In some embodiments, as Figure 1 shown. The extension platform 200 is connected to the workbench 100 through a series of movable connectors. These connectors are designed to enable the extension platform 200 to move parallel to the first standing surface 110. The movable connectors can adopt mechanisms such as slide rails and guide rails to enable the extension platform 200 to move smoothly inside and outside the workbench 100. According to the weight and usage frequency of the extension platform 200, the connectors can also be equipped with a locking mechanism to automatically lock when the extension platform 200 reaches a specific position to ensure safety.

[0059] Specifically, the material of the movable connector should be selected as wear-resistant and fatigue-resistant metal or high-strength synthetic materials, such as stainless steel, titanium alloy or engineering plastics. These materials can withstand the wear under long-term use and maintain the stability and smoothness of the connector.

[0060] In this embodiment, through the reasonably designed movable connector, the expansion platform 200 can be smoothly joined or retracted with the workbench 100, avoiding potential safety hazards caused by jamming or loosening during the moving process. The movable connector has high precision and high durability during the controlled movement process, ensuring the reliable operation of the expansion platform 200 under complex operating conditions.

[0061] The expansion platform 200 can also be made of aluminum alloy or steel to ensure its stability and durability during the controlled movement process. At the same time, in order to reduce the overall weight of the expansion platform 200, a hollow design can be used inside the platform, or lightweight but strong composite materials can be adopted. In addition, the same anti-slip coating as the workbench 100 can be used on the platform surface to ensure consistent operating safety.

[0062] The main function of the expansion platform 200 is to provide an additional working area for maintenance personnel, especially in situations where multiple operators need to work simultaneously or place tool equipment. The seamless joining design of the expansion platform 200 and the workbench 100 ensures the continuity of the working area, enabling maintenance personnel to operate stably and safely in the expanded state. At the same time, through the controlled movement mechanism, the expansion and retraction process of the expansion platform 200 can be precisely controlled, avoiding safety problems caused by misoperation.

[0063] The moving method of the expansion platform 200 can be designed diversely according to specific requirements. In addition to electric drive, a mechanical slide rail system can also be selected, combined with pneumatic or hydraulic devices, to ensure the smooth movement of the expansion platform 200. In addition, the structure of the expansion platform 200 can also be modularly designed according to the usage requirements, facilitating the flexible adjustment of the expansion range of the platform in different situations.

[0064] It should be noted that the switching between the expanded state and the normal state of the maintenance platform can be achieved through a control system, which includes the drive mechanism 300 or manual control device described later. The drive mechanism 300 can be controlled by the motor 310 and cooperate with the wheel-belt drive system to realize the automatic movement of the expansion platform 200.

[0065] The control system enables the movement process of the expansion platform 200 to be more precise and efficient, reducing the errors and inconveniences of manual operation. At the same time, through the design of sensors or controllers, the platform can automatically stop or lock when it reaches the preset position, further improving the safety and convenience of operation.

[0066] In some embodiments, as Figure 1 shown. To align the side edges of the extended platform 200 pulled out with the edges of the corresponding sides of the workbench 100, the extended platform 200 includes a main platform 220 and a side platform 230. The main platform 220 is movably connected to the workbench 100 and is controlled to move. The side platform 230 is movably connected to the main platform 220, the side platform 230 is controlled to move, and the side platform 230 is arranged parallel to the main platform 220. When the extended platform 200 is in the working state, the side platform 230 is controlled to move outside the main platform 220, and the side of the main platform 220 facing away from the base 120 and the side of the side platform 230 facing away from the base 120 are joined together to form a second standing surface 210.

[0067] Specifically, the maintenance platform in this embodiment is composed of the workbench 100, the main platform 220 and the side platform 230. The extended platform 200 is movably connected to the workbench 100 through the main platform 220, and the working area is further enlarged by the side platform 230. The main platform 220 can be controlled to move from the inside of the workbench 100 to the outside, and the side platform 230 moves parallel to the main platform 220 to form a complete extended working plane. When the extended platform 200 is in the working state, the main platform 220 and the side platform 230 together form a second standing surface 210, which is joined with the first standing surface 110 of the workbench 100 to ensure seamless docking of the standing surfaces. This structure solves the problem that the existing maintenance platform cannot be aligned with the workbench 100 during extension, ensures that the standing surface remains continuous and flat after the extended platform 200 is pulled out, and provides a larger operating space. In addition, the multiple movable connection design of the extended platform 200 allows maintenance personnel to adjust the extension degree of the platform according to needs, improving the flexibility of the system.

[0068] The main platform 220 is the main load-bearing part of the extended platform 200, is connected to the workbench 100 through a movable connecting piece, and can move between the inside and the outside of the workbench 100. The moving track of the main platform 220 is parallel to the first standing surface 110, which ensures that the main platform 220 remains consistent with the edge of the workbench 100 during the moving process. When the main platform 220 moves outside the workbench 100, the side facing away from the base 120 will be joined with the side platform 230 to form a second standing surface 210.

[0069] The main platform 220 should be made of a strong and lightweight material, such as aluminum alloy or high-strength composite material, to ensure that it can bear the weight of maintenance personnel and tools during the moving process without increasing the total weight of the maintenance platform. The platform surface should be covered with an anti-slip coating to increase safety during work.

[0070] The main platform 220, as the core part of the extended platform 200, provides a major additional standing area. Through the movable connection, the main platform 220 can be stored inside the workbench 100 and provide sufficient standing space for maintenance personnel in the extended state. At the same time, the combined design of the main platform 220 and the side platform 230 ensures that the standing surface after extension is aligned with the side edge of the first standing surface 110 of the workbench 100, enhancing the continuity and safety of operations.

[0071] The design of the main platform 220 can be adjusted according to different scenario requirements. For example, the size of the main platform 220 can be expanded or reduced according to the size of the operation space. In addition, the movable connection method of the main platform 220 can use mechanical slide rails or electric sliding devices according to the requirements of different environments.

[0072] The side platform 230 is arranged parallel to the main platform 220 through a movable connection and can move between the outside and inside of the main platform 220. When the extended platform 200 is in the working state, the side platform 230 moves to the outside of the main platform 220, so that the sides of the main platform 220 and the side platform 230 facing away from the base 120 are combined to form the second standing surface 210. The design of the side platform 230 enables it to provide further extended standing space after the main platform 220 moves to the outside of the workbench 100.

[0073] The side platform 230 also needs to use lightweight but strong materials, such as aluminum alloy or high-strength plastic, to reduce the overall weight of the extended platform 200. The design of the side platform 230 should be as simplified as possible to ensure stability during parallel movement. An anti-slip coating is also necessary to ensure that maintenance personnel stand firmly during work.

[0074] The function of the side platform 230 is to further expand the standing area and form a complete second standing surface 210 by combining with the main platform 220 in the working state. Through the movement of the side platform 230, the total standing area of the extended platform 200 is increased, and maintenance personnel can operate on a wider working surface, which is especially suitable for multi-person collaboration or maintenance work that requires more equipment.

[0075] The connecting parts and control method of the side platform 230 and the main platform 220 are similar to those of the extended platform 200 and the workbench 100. Moreover, the control method of the side platform 230 and the main platform 220 preferably adopts manual control.

[0076] In this embodiment, the design of the main platform 220 and the side platform 230 realizes the flexible movement and splicing of the extension platform 200, so that the extension platform 200 can be docked with the first standing surface 110 of the workbench 100 in the working state to form a complete working plane. The movable connection design of the main platform 220 and the side platform 230 ensures the stability and safety of the extension platform 200 during the movement, and the addition of the control system further improves the operating efficiency and accuracy of the extension platform 200. The improved design of this embodiment provides a larger standing area for the maintenance platform in the extended state, which improves the work efficiency and safety of maintenance personnel.

[0077] In order to improve the security and protection performance of the maintenance platform in the extended state, such as Figures 1 to 3 A maintenance platform further includes a guardrail assembly 400, which is vertically arranged with respect to the first standing surface 110 and the second standing surface 210. The guardrail assembly 400 includes a fixed guardrail 410 and a movable guardrail 420. The fixed guardrail 410 is arranged around the peripheral edge of the first standing surface 110 of the workbench 100, and a first opening 111 is opened on one side of the fixed guardrail 410. The movable guardrail 420 includes an end guardrail 421 and a side guardrail 422. The end guardrail 421 is arranged on the side of the expansion platform 200 away from the workbench 100, and the end guardrail 421 is located at the first opening 111 when the maintenance platform is in a normal state, so as to enclose with the fixed guardrail 410 to form a first annular guardrail, and the side guardrail 422 connects the fixed guardrail 410 and the end guardrail 421 when the maintenance platform is in an expanded state, so as to enclose to form a second annular guardrail.

[0078] Specifically, this embodiment provides a maintenance platform, which is specially designed for safety and protection performance in the extended state, and a guardrail assembly 400 is newly added. Through the cooperation of the guardrail assembly 400 with the workbench 100 and the extended platform 200, complete protection in the extended state is achieved, which prevents personnel or tools from accidentally falling, and improves the safety of maintenance operations. The guardrail assembly 400 in this embodiment is flexibly designed and can adapt to different working states of the maintenance platform, providing stable safety protection in both the normal state and the extended state.

[0079] Further, in order to align the side guardrail 422 with the edge of the extended platform 200 when the maintenance platform is in the extended state. The end guardrail 421 includes a main guardrail 4211 and a side pull bar 4212. The main guardrail 4211 is disposed on the side of the extended platform 200 away from the workbench 100. The side pull bar 4212 is disposed on the side of the main guardrail 4211, and the side pull bar 4212 is movably connected to the main guardrail 4211. When the maintenance platform is in the extended state, the side pull bar 4212 moves in a direction away from the main guardrail 4211 to a preset position, so that both the opposite sides of the main guardrail 4211 and the side pull bar 4212 are connected to the side guardrail 422 to form the aforementioned second annular guardrail.

[0080] Specifically, the maintenance platform in this embodiment includes a workbench 100, an extended platform 200, and a guardrail assembly 400. The guardrail assembly 400 is perpendicularly disposed with respect to the first standing surface 110 of the workbench 100 and the second standing surface 210 of the extended platform 200, ensuring that the surrounding protective structure remains intact when the platform is in the extended or normal state. The guardrail assembly 400 is divided into two parts: a fixed guardrail 410 and a movable guardrail 420. Among them, the fixed guardrail 410 mainly surrounds the periphery of the first standing surface 110 of the workbench 100, and the movable guardrail 420 provides additional protection when the platform is in the extended state according to the movement of the extended platform 200.

[0081] The guardrail assembly 400 solves the defect of incomplete protection of the existing maintenance platform in the extended state, ensuring that the operating space of the extended platform 200 also has safety protection performance. Through the flexible design of the movable guardrail 420, it is ensured that the guardrail assembly 400 can be aligned and connected as the maintenance platform expands in the extended state.

[0082] The guardrail assembly 400 includes two parts: a fixed guardrail 410 and a movable guardrail 420. The fixed guardrail 410 is disposed on the peripheral edge of the first standing surface 110 of the workbench 100 to form a protective structure of the maintenance platform in the normal state. The movable guardrail 420 includes an end guardrail 421 and a side guardrail 422. The end guardrail 421 is located on the side of the extended platform 200 away from the workbench 100 and cooperates with the fixed guardrail 410 to form a complete protective ring in the normal state. The side guardrail 422 is used for connection in the extended state.

[0083] The main material of the guardrail assembly 400 can be selected as a lightweight and strong metal material, such as aluminum alloy or stainless steel, to ensure that it does not increase the overall weight of the platform while providing safety protection. The surface of the guardrail assembly 400 can be covered with an anti-corrosion coating to improve its durability in various industrial environments.

[0084] The main function of the guardrail assembly 400 is to ensure that the protection performance of the maintenance platform in the extended state is not affected. Through the combined design of the fixed guardrail 410 and the movable guardrail 420, when the maintenance platform is extended, the guardrail assembly 400 can extend as the extended platform 200 is pulled out, thus forming a complete protective structure to prevent personnel or tools from accidentally falling and improving operational safety.

[0085] Among them, the fixed guardrail 410 is arranged around the periphery of the first standing surface 110 of the workbench 100 to form a first annular guardrail for providing protection in the normal state. A first opening 111 is provided on one side of the fixed guardrail 410 to facilitate the splicing and extension of the movable guardrail 420 with the fixed guardrail 410.

[0086] The fixed guardrail 410 can also be made of strong aluminum alloy or stainless steel materials, with high impact resistance and corrosion resistance. Its surface can be coated with anti-slip or anti-corrosion coatings to extend the service life and enhance the protection effect.

[0087] As the basic structure of the guardrail assembly 400, the fixed guardrail 410 ensures the protection effect in the normal state. The design of the first opening 111 facilitates the cooperation with the movable guardrail 420 in the extended state to realize the extension of the protective structure.

[0088] The movable guardrail 420 includes an end guardrail 421 and a side guardrail 422. The end guardrail 421 is located on the side of the extended platform 200 away from the workbench 100. When the maintenance platform is in the normal state, the end guardrail 421 is connected to the fixed guardrail 410 through the first opening 111 to form a first annular guardrail. In the extended state, the side guardrail 422 connects the fixed guardrail 410 and the end guardrail 421 to form a second annular guardrail, ensuring the safety protection of the extended platform 200. In some embodiments, the side guardrail 422 is composed of several strip-shaped members, and the two ends of the strip-shaped members are respectively connected to the fixed guardrail 410 and the end guardrail 421 when the maintenance platform is in the extended state. The specific connection can be a snap connection or a fastener connection.

[0089] The material of the movable guardrail 420 is similar to that of the fixed guardrail 410, and aluminum alloy, stainless steel or composite materials can be selected to ensure sufficient strength and durability during the controlled movement process. The connecting parts between the side guardrail 422 and the end guardrail 421 should be made of high-strength materials to ensure the firm splicing between the guardrails without loosening or misalignment.

[0090] The design of the movable guardrail 420 ensures the protection integrity of the extended platform 200 in the extended state. When the extended platform 200 is pulled out, the side guardrail 422 connects the fixed guardrail 410 and the end guardrail 421 to form a complete second annular guardrail, effectively preventing personnel or tools from falling and enhancing the safety performance.

[0091] Furthermore, the end guardrail 421 includes a main guardrail 4211 and a side pull bar 4212. The main guardrail 4211 is located on the side of the extended platform 200 facing away from the workbench 100, and the side pull bar 4212 is arranged on the side of the main guardrail 4211 and is movably connected to the main guardrail 4211. When the maintenance platform is in the extended state, the side pull bar 4212 moves in a direction away from the main guardrail 4211 to a preset position and is connected to the side guardrail 422 to form a complete second circular guardrail.

[0092] The material of the end guardrail 421 should have good impact resistance and durability. It is recommended to use aluminum alloy or stainless steel. The movable connection components of the side pull bar 4212 should be made of wear-resistant materials such as stainless steel or high-strength plastic to ensure that the connection part remains stable and smooth after multiple operations.

[0093] When the extended platform 200 is in the extended state, the end guardrail 421 can be docked with the side guardrail 422 through the movement of the side pull bar 4212 to form a complete protective structure. The movable connection design improves the flexibility of the guardrail and ensures that the protective performance in the extended state is not affected.

[0094] The design of the end guardrail 421 can be flexibly adjusted according to the expansion requirements of the maintenance platform. The movable connection method of the side pull bar 4212 can be changed to a slide rail type to cooperate with the synchronous movement of the platform expansion. In addition, the end guardrail 421 can also be designed as a folding structure and can be stored inside the main guardrail 4211 when not needed, which is convenient for storage and transportation.

[0095] The side guardrail 422 connects the fixed guardrail 410 and the end guardrail 421 in the extended state to form a second circular guardrail. The design of the side guardrail 422 enables it to align with the edge of the extended platform 200 in the extended state to ensure the integrity of the protective structure.

[0096] The side guardrail 422 needs to select light and strong materials such as aluminum alloy or carbon fiber material to reduce the impact on the movement of the extended platform 200. Its connection components should have good wear resistance and corrosion resistance to cope with long-term use.

[0097] The design of the side guardrail 422 ensures the continuity and alignment of the protective structure of the extended platform 200 in the extended state. By fitting with the fixed guardrail 410 and the end guardrail 421, the side guardrail 422 forms a complete protective circle around the extended platform 200, further enhancing the safety.

[0098] The side guardrail 422 can adopt a telescopic design and automatically retract when the extended platform 200 contracts, reducing the operation of manual intervention. In addition, the connection parts of the side guardrail 422 can be designed as quick buckles, which are convenient for quick disassembly and adjustment.

[0099] In this embodiment, through the combined design of the fixed guardrail 410 and the movable guardrail 420, comprehensive protection of the maintenance platform in the extended state and the normal state is achieved. The guardrail assembly 400 can be flexibly adjusted along with the movement of the extended platform 200 to ensure that the protection performance of the maintenance platform is not affected. Through the movable connection of the end guardrail 421 and the splicing design of the side guardrail 422, the extended platform 200 can still maintain a safe and stable working environment in the extended state.

[0100] For the convenience of maintenance personnel to enter and exit, the fixed guardrail 410 is provided with a second opening 411, and the fixed guardrail 410 further includes a switch door 412 which is arranged at the second opening 411. The second opening 411 has a passing state and a closed state. When the second opening 411 is in the passing state, the switch door 412 moves relative to the fixed guardrail 410 to make the second opening 411 in an open state. When the second opening 411 is in the closed state, the opposite sides of the switch door 412 are respectively connected to the opposite sides of the second opening 411 to restrict the movement of the switch door 412 relative to the fixed guardrail 410 and close the second opening 411.

[0101] The guardrail assembly 400 of the maintenance platform includes a fixed guardrail 410 and a switch door 412, and the second opening 411 is arranged on one side of the fixed guardrail 410. The second opening 411 is controlled by the switch door 412 and can be switched between a closed state and a passing state. The fixed guardrail 410 provides basic peripheral protection for the maintenance platform, and the design of the switch door 412 provides a passage for maintenance personnel to enter and exit. Through this design, the maintenance platform can flexibly adjust the state of the guardrail when entering or leaving, ensuring safety and protection within the working area.

[0102] The above structure mainly solves the problem that it is inconvenient for maintenance personnel to enter and exit in the prior art. By arranging the switch door 412 on the fixed guardrail 410, maintenance personnel can safely enter and exit through the second opening 411 without affecting the protection performance of other parts.

[0103] The fixed guardrail 410 is the main protection structure around the maintenance platform, which is arranged around the platform and plays a basic safety protection role. The design of the fixed guardrail 410 is arranged around the standing surface of the platform to provide a comprehensive safety fence. On one side of the fixed guardrail 410, a second opening 411 is provided for maintenance personnel to enter and exit the working area of the platform.

[0104] The design of the fixed guardrail 410 ensures the safety of the maintenance platform during daily operations, forming an enclosed working space. By setting the second opening 411 on the fixed guardrail 410, a flexible import and export design is provided, facilitating the entry and exit of maintenance personnel into the work area without the need to disassemble the guardrail. At the same time, the robust structure of the fixed guardrail 410 guarantees its impact resistance and durability, ensuring the safety around the maintenance platform.

[0105] The position and quantity of the second opening 411 of the fixed guardrail 410 can also be adjusted according to the layout of the maintenance platform to provide more import and export channels.

[0106] The second opening 411 is located on one side of the fixed guardrail 410 and serves as the entrance and exit for maintenance personnel. The second opening 411 can be closed or opened by the opening or closing of the switch door 412. When in the passage state, the second opening 411 is open, and maintenance personnel can freely enter and exit the platform. When in the closed state, the switch door 412 closes the second opening 411 to ensure the protective integrity of the guardrail.

[0107] The periphery of the second opening 411 should be strengthened to ensure that the switch door 412 can move smoothly and precisely within the opening. Further, the edge of the second opening 411 should use the same material as the fixed guardrail 410 to ensure consistent strength and durability.

[0108] The setting of the second opening 411 facilitates the entry and exit of maintenance personnel on the work platform. Especially when frequent entry and exit or carrying tools are required, it can significantly improve the convenience of operation. Through the design of the second opening 411, the trouble of completely disassembling or moving the traditional guardrail is avoided, ensuring the balance between convenient access and safety protection.

[0109] The size of the second opening 411 can be adjusted according to the specific requirements of the maintenance platform, increasing the width to accommodate the entry and exit of larger equipment or tools. In addition, the position of the second opening 411 can also be optimized according to the layout of the platform to ensure the convenience of import and export.

[0110] The movement mechanism of the switch door 412 can adopt a sliding track or hinge connection design. The sliding door design can provide flexible opening and closing operations in a limited space, while the hinge door design can achieve a larger opening angle. The movement range of the switch door 412 is restricted by the edge of the second opening 411. When the switch door 412 is closed, both sides are firmly connected to the opening edge to ensure safety in the closed state.

[0111] Moving parts such as slide rails or hinges should use high-strength metal materials, such as stainless steel or titanium alloy, to ensure their wear resistance and smoothness during frequent use. To ensure service life and stability, the moving parts should also be equipped with self-lubricating materials or structures to reduce frictional losses.

[0112] In this embodiment, through the design of the slide rail or hinge, the switch door 412 can move smoothly and smoothly within the second opening 411, and the operation is simple and convenient. When in the closed state, the movement mechanism can ensure that the switch door 412 is tightly combined with the guardrail without loosening or accidental opening, ensuring the safety protection of the platform.

[0113] The movement mechanism of the switch door 412 can be designed differently according to actual needs. For example, in order to improve the automation of the operation, an electric control system can be introduced to enable the switch door 412 to open and close automatically through buttons or remote control. In addition, a mechanical locking device can further enhance the safety in the closed state and prevent misoperation or accidental opening.

[0114] To drive the extension platform 200 to move relative to the workbench 100, as Figure 4 shown. The maintenance platform further includes a driving mechanism 300. The driving mechanism 300 includes a motor 310, a driving wheel 320, a driven wheel 330, a transmission belt 340, a driving member 350, and a torque limiter 360. The motor 310 is connected to the workbench 100. The torque limiter 360 is arranged on the workbench 100. The output shaft of the motor 310 is connected to the input end of the torque limiter 360. The output end of the torque limiter 360 is connected to the driving wheel 320 so that the driving wheel 320 rotates synchronously with the output end of the torque limiter 360. The driven wheel 330 is arranged in parallel with the driving wheel 320. The driven wheel 330 is rotatably connected to the workbench 100, and the rotation axis of the driven wheel 330 coincides with its own axis. The driving wheel 320 is drivingly connected to the driven wheel 330 through the transmission belt 340 so that the driven wheel 330 and the driving wheel 320 rotate. The driving member 350 is fixedly connected to one side of the transmission belt 340. The driving member 350 is connected to the extension platform 200. At this time, the movement track of the driving member 350 is parallel to a part of the movement track of the transmission belt 340, and the specific movement track of the driving member 350 is a straight line.

[0115] This embodiment provides a driving mechanism 300 for driving the extension platform 200 of the maintenance platform to move relative to the workbench 100. The driving mechanism 300 realizes the smooth movement of the extension platform 200 through the motor 310, the driving wheel 320, the driven wheel 330, the transmission belt 340, the driving member 350, and the torque limiter 360, and avoids overload or mechanical damage. The linear movement design of the driving member 350 ensures the smoothness and accuracy of the extension platform 200 during operation, thereby improving the maintenance efficiency and the service life of the equipment.

[0116] The drive mechanism 300 consists of multiple mechanical and electrical components and is used to control the controlled movement of the extension platform 200 relative to the workbench 100. By driving the transmission system with the motor 310, the extension platform 200 can move parallel to the workbench 100. The movement trajectory of the driving member 350 is parallel to a part of the trajectory of the transmission belt 340, ensuring the linearity and stability of the movement of the extension platform 200. The torque limiter 360 in the drive mechanism 300 plays an important protective role, preventing damage to the transmission system or the extension platform 200 caused by the overload of the motor 310.

[0117] This drive mechanism 300 solves the problem of the cumbersome operation of the traditional manual movement of the extension platform 200, improves the automation level of the extension platform 200, ensures the efficiency and accuracy of the maintenance operation, and at the same time improves the safety of the transmission system through the torque limiter 360.

[0118] The motor 310 is fixedly connected to the workbench 100 and serves as the core power source of the drive mechanism 300. The output shaft of the motor 310 is connected to the driving wheel 320 through the torque limiter 360 to control the overall operation of the transmission system. The motor 310 provides power for the movement of the extension platform 200, ensuring that the extension platform 200 moves under controlled conditions. The output of the motor 310 can cooperate with the torque limiter 360 to prevent damage to the transmission system due to overload or current fluctuations.

[0119] The motor 310 can select models with different powers according to the load requirements of the extension platform 200, or use a servo motor 310 to improve the control accuracy. In addition, in order to further improve the safety of the equipment, a dual-motor 310 redundancy design can also be introduced to ensure that the system can still operate when one motor 310 fails.

[0120] The torque limiter 360 is arranged on the workbench 100. The output shaft of the motor 310 is connected to the input end of the torque limiter 360, and the output end of the torque limiter 360 is connected to the driving wheel 320. The torque limiter 360 is used to automatically limit the torque output of the transmission system when the output of the motor 310 is overloaded or the system operates abnormally, thereby protecting the transmission components from damage.

[0121] In this embodiment, through the action of the torque limiter 360, the drive mechanism 300 can prevent damage to the motor 310 or the transmission system under overload conditions, playing a role in protecting the entire drive system. It can effectively prevent mechanical failures caused by excessive loads or operational errors and extend the service life of the maintenance platform.

[0122] The torque limiter 360 can be adjusted according to different safety requirements. For high-precision equipment, the use of electronic torque limiters can further improve the accuracy and response speed of protection. For simpler application scenarios, mechanical torque limiters can also be used to reduce costs.

[0123] The driving wheel 320 is connected to the motor 310 through the torque limiter 360, and the driving wheel 320 is connected to the transmission belt 340 to drive the operation of the transmission system. The transmission wheel 330 is arranged in parallel on the workbench 100, and is connected to the driving wheel 320 through the transmission belt 340. The transmission wheel 330 keeps synchronization with the movement of the expansion platform 200.

[0124] In this embodiment, the expansion platform 200 can stably and accurately move along the workbench 100 through the cooperation of the driving wheel 320 and the transmission wheel 330. The parallel design of the driving wheel 320 and the transmission wheel 330 ensures the linearity of the movement of the expansion platform 200 and avoids the platform from deflecting or getting stuck during the movement.

[0125] The transmission belt 340 is connected to the transmission wheel 330 through the driving wheel 320 to transmit the rotational power of the motor 310. The transmission belt 340 cooperates with the driving wheel 320 and the transmission wheel 330 to drive the driving member 350 to move, so that the expansion platform 200 moves parallel to the workbench 100.

[0126] The transmission belt 340, as a core component of power transmission, ensures the smooth movement of the expansion platform 200. Its high-strength material and anti-skid design ensure the reliability and stability of the platform movement, avoiding slippage or poor transmission under high load.

[0127] The driving member 350 is fixedly connected to one side of the transmission belt 340, and the driving member 350 is connected to the expansion platform 200. Through the rotation of the transmission belt 340, the driving member 350 moves along the track of the transmission belt 340, thereby driving the expansion platform 200 to move relative to the workbench 100. The moving track of the driving member 350 is a straight line, which partially overlaps with the moving track of the transmission belt 340, ensuring the smooth linear movement of the expansion platform 200.

[0128] The driving member 350 should be made of high-strength metal materials, such as aluminum alloy or stainless steel, to ensure that it can operate stably under high loads. The connection portion between it and the transmission belt 340 should be made of wear-resistant materials to reduce friction loss and extend service life.

[0129] The driving member 350 is a key component for the movement of the extension platform 200, and can ensure the parallel movement of the extension platform 200 along the workbench 100. Its linear motion trajectory ensures that the extension platform 200 will not deviate during the movement, ensuring the safety and stability of the maintenance personnel during operation.

[0130] In this embodiment, the drive mechanism 300 realizes the automatic movement control of the extension platform 200 through the combination of the motor 310, the torque limiter 360, the driving wheel 320, the transmission belt 340 and the driving member 350. This drive system ensures the smooth movement of the extension platform 200, reduces human intervention, and improves operation efficiency and safety. Through the design of the torque limiter 360, the system is effectively protected under overload conditions, the service life of the equipment is extended, and the failure risk is reduced.

[0131] What is described above in this specification is only an example of the present utility model. Those skilled in the technical field to which the present utility model belongs can make various modifications or supplements to the described specific embodiments or use similar methods for substitution, as long as they do not deviate from the content of this specification of the present utility model or exceed the scope defined by this claims, they should all fall within the protection scope of the present utility model.
