Description

Technical Field

[0001] This invention relates to the field of scaffolding, and in particular to a splicable insulated scaffolding device for 10kV live-line work. Background Technology

[0002] In 10kV live-line work, to ensure the safety of workers and achieve equipotential or ground potential operation, scaffolding devices with good insulation properties are often used as working platforms. However, existing insulated scaffolding used at this voltage level is often structurally complex. Taking CN205791218U as an example, it typically consists of multiple horizontal bars, diagonal bars, guardrails, stairs, outriggers, and locking mechanisms, with a single layer assembly involving more than ten components. Such devices present problems in field use, including inconvenience in handling and the risk of losing components. The assembly process requires frequent transfer and connection of components, making the operation cumbersome. This not only increases the risk of falling objects and accidental injury from heights but also consumes a significant amount of the workers' physical strength and time during the assembly stage before live-line work, affecting work efficiency and subsequent operations. Summary of the Invention

[0003] The purpose of this invention is to provide a splicable insulated scaffolding device for 10kV live-line work, which solves the problem of inconvenient use of existing scaffolding and makes scaffolding use more convenient.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a splicable insulated scaffolding device for 10kV live-line work, comprising a base, a pole attachment mechanism, and multiple insulated support modules. The insulated support module is composed of multiple insulated rods spliced ​​together through connecting nodes. The multiple insulated support modules are spliced ​​layer by layer in the vertical direction. The bottom layer of the insulated support module is detachably connected to the base. At least one lateral side of the insulated support module has a foldable or telescopic structure, allowing the insulated support module to be folded or unfolded laterally. The pole attachment mechanism is detachably connected to the side of the insulated support module for fixing the insulated scaffolding device to the pole and providing lateral support.

[0005] By adopting the above technical solution, the present invention has the following advantages: the insulating load-bearing module supports ground pre-assembly, allowing workers to unfold and assemble the insulating load-bearing module on the ground before lifting the formed structure to the work position. Each insulating load-bearing module is quickly connected via connection nodes, significantly reducing high-altitude assembly operations, improving safety and efficiency, and making installation more convenient. It also avoids the problems of numerous and easily lost parts associated with traditional scaffolding. Each module's lateral sides adopt a foldable or telescopic pole structure, allowing it to be folded up during transport, significantly reducing its size and facilitating carrying and on-site transfer. Simultaneously, a detachable pole attachment mechanism is added to the side of the insulating load-bearing module to firmly fix the scaffolding to the pole and provide reliable lateral support, enhancing overall stability during high-altitude operations and minimizing the risk of the insulating scaffolding device tipping over.

[0006] Furthermore, a foldable or retractable diagonal brace is provided between adjacent insulating load-bearing modules, and the two ends of the diagonal brace are detachably connected between the lateral sides of the adjacent insulating load-bearing modules.

[0007] By employing the aforementioned technical solution, foldable or retractable diagonal braces are installed between adjacent insulating load-bearing modules. Both ends of these braces are detachably connected to the lateral sides of the upper and lower insulating load-bearing modules, enhancing not only the overall structural integrity but also significantly improving the stability and safety of the scaffolding. When unfolded, these diagonal braces form diagonal supports, effectively increasing the connection stiffness between the insulating load-bearing modules, suppressing swaying and lateral deformation of the multi-layered structure during high-altitude operations, and enhancing anti-overturning capabilities. Together with the side pole attachment mechanism, they form a dual stabilization system of lateral fixation and diagonal reinforcement. Furthermore, the foldable or retractable design of the diagonal braces, combined with the folding function of the insulating load-bearing modules themselves, allows for simultaneous folding during disassembly or retraction without increasing storage volume, maintaining the overall portability and ease of transportation of the device, and balancing structural reinforcement with rapid assembly and disassembly requirements.

[0008] Furthermore, the diagonal brace is positioned on the same lateral side as the foldable or retractable side, so that the diagonal brace can be folded or extended synchronously with the lateral side.

[0009] By adopting the aforementioned technical solution, an integrated design of the diagonal brace and the lateral side of the insulating load-bearing module in terms of movement trajectory is achieved. This allows the diagonal brace to fold synchronously with the side structure when retracted and extend synchronously when unfolded, eliminating the need for separate operation, simplifying the assembly and disassembly process, and improving work efficiency. The highly coordinated structure minimizes interference between the diagonal brace and other components during the folding process, ensuring smooth operation and accurate positioning as much as possible.

[0010] Furthermore, two sets of diagonal braces are provided between the two opposite lateral sides of the insulating load-bearing module, and the two sets of diagonal braces are arranged in opposite directions and cross each other.

[0011] Compared to single-sided or unidirectional diagonal bracing, the cross-bracing arrangement results in more even stress distribution, stronger overall stability, and significantly improved safety margin of the aerial work platform. Furthermore, while ensuring high-strength support, the structure can still maintain its compactness and portability by designing the diagonal bracing rods to be foldable or retractable, allowing them to be folded in sync with the lateral sides.

[0012] Furthermore, both the diagonal brace and the insulating rod on the lateral side include a first rod, a second rod, and a hinge connecting the two and enabling folding.

[0013] The above technical solution ensures that the diagonal brace and the lateral side are consistent in their folding mechanism, and achieves smooth folding and unfolding through the hinge. The structure is simpler and the operation is more reliable.

[0014] Furthermore, the first and second members of the diagonal brace have different lengths.

[0015] With the above technical solution, if the first and second struts of the diagonal brace are designed to be of equal length, the two ends will symmetrically converge towards the center during folding. This results in the hinge point and the connecting nodes at both ends being too close in the later stages of folding, causing serious spatial conflicts. Especially when approaching the fully folded state, jamming or failure to close may occur, affecting the smoothness of operation and the compactness of the structure. Adopting a long-short strut design, where the first and second struts are of unequal length, effectively staggers the movement trajectories of various components during folding and the final folding position, avoiding spatial interference between the hinge point, struts, and connecting nodes. This significantly reduces the risk of friction and collision, making the folding action smoother and more reliable. Simultaneously, the long-short strut structure allows the shorter end to converge closer to the inner side of the main frame, further compressing the overall envelope size and improving storage efficiency and portability.

[0016] Furthermore, the connection node is a snap-fit, pin-type connector, threaded connector, quick-connect connector, or flange connection plate, used to realize a detachable connection between insulating rods.

[0017] The above technical solution supports operation by hand or with simple tools, without the need for complex fastening equipment, and is convenient for working at heights or in confined spaces.

[0018] Furthermore, the pole attachment mechanism includes a clamp, a first connecting rod, and a second connecting rod. One end of the first connecting rod and one end of the second connecting rod are respectively connected to the two sides of the foldable or telescopic lateral side. The other ends of the first connecting rod and the second connecting rod are hinged to the clamp. When the pole attachment mechanism is installed on the pole and unfolded, the first connecting rod, the second connecting rod, and the two ends of the lateral side form a triangular support structure, which restricts the relative movement of the lateral side.

[0019] By utilizing the principle of geometric invariance, a rigid support system is constructed between the scaffolding platform and the utility pole through the above technical solution. This effectively restricts the relative movement of the lateral sides in the extended state, preventing them from shrinking or deforming under stress, thus ensuring the stability of the working platform's width and structural reliability. Simultaneously, this linkage structure automatically tensions during deployment, achieving self-stabilization without the need for additional locking devices, making operation simple and responsive. The hinged connection allows each component to flexibly adapt to the curvature of utility poles of different diameters, improving the device's versatility and fit. The pole attachment mechanism works in conjunction with the foldable / telescopic lateral sides: in the retracted state, the first and second connecting rods fold synchronously with the lateral sides without increasing storage volume; after deployment, they automatically form constraints, achieving the function of immediate fixation upon deployment, balancing portability and operational safety.

[0020] Furthermore, the connection node includes a first gripper and a second gripper located at the end of the insulating rod. The first gripper is located outside the second gripper and has a greater range of rotation than the second gripper. The second gripper has a first position for attaching other insulating rods and a second position for being pushed by the first gripper to flip to avoid other insulating rods when the first gripper rotates toward the second gripper.

[0021] With the above technical solution, during installation, simply press the insulating rod down and then lift it slightly; the second gripper will automatically lock onto the horizontal insulating rod, achieving quick fixation. For height adjustment, simply push the other insulating rods down to rotate the second gripper, then push the insulating rod upward. The first gripper will rotate due to the horizontal insulating rod, and during this rotation, it will push the second gripper to flip and disengage, allowing it to smoothly pass over other insulating rods, achieving interference-free lifting. The entire process requires no disassembly, flipping, or additional operation of the insulating rods, significantly improving work efficiency and site adaptability.

[0022] Furthermore, the lateral side of the insulating load-bearing module is connected to a side support mechanism, which includes a first support rod and a second support rod. One end of the first support rod can be supported on the ground, and the other end is hinged to one end of the second support rod. The other ends of the first support rod and the second support rod are detachably fixed to different connection positions on the lateral side to adjust the support angle.

[0023] The above technical solution utilizes a double-bar hinged structure to form an adjustable diagonal brace. The first support bar is directly grounded, effectively transferring part of the vertical and lateral loads of the working platform to the ground. This significantly improves the overall load-bearing capacity and anti-overturning performance of the scaffolding, making it particularly suitable for soft or unevenly stressed working environments. The detachable connection facilitates quick installation and disassembly. The side support mechanism can be completely removed when not needed without affecting module folding and transportation. By connecting the upper ends of the first and second support bars to different positions on the lateral side, the geometry of the support triangle can be flexibly adjusted, thereby adjusting the support angle. This allows the mechanism to adapt to different heights, distances, and ground slopes, enhancing its on-site adaptability. Attached Figure Description

[0041] The technical solution of the present invention will be described in detail below with reference to specific embodiments. The following specific embodiments may be combined or substituted with each other according to the actual situation, and the same or similar concepts or processes may not be described again in some embodiments.

[0042] like Figures 1 to 10 As shown, the present invention provides a splicable insulated scaffolding device for 10kV live-line work, including a base 10, a pole attachment mechanism 20, and multiple insulated support modules 30. The insulated support module 30 is composed of multiple insulated rods 31 spliced ​​together by connecting nodes 32. The multiple insulated support modules 30 are spliced ​​layer by layer in the vertical direction. The bottom layer of the insulated support module 30 is detachably connected to the base 10. The insulated rods 31 on the two opposite lateral sides of the insulated support module 30 have a foldable structure, so that the insulated support module 30 can be folded or unfolded laterally. The pole attachment mechanism 20 is detachably connected to the side of the insulated support module 30 for fixing the insulated scaffolding device to the pole 60 and providing lateral support.

[0043] The insulating support modules 30 of the aforementioned insulated scaffolding device support ground pre-assembly, allowing workers to unfold and assemble the modules on the ground before lifting the completed structure to the work position. The modules 30 are quickly connected via connection nodes 32, significantly reducing high-altitude assembly operations, improving safety and efficiency, and making installation more convenient. This avoids the problems of numerous and easily lost parts associated with traditional scaffolding. Each module's lateral sides feature foldable or retractable pole structures, allowing for folding during transport, significantly reducing volume and facilitating carrying and on-site transfer. Simultaneously, a detachable pole attachment mechanism 20 is added to the side of the insulating support module 30 to securely fix the scaffolding to the pole 60 and provide reliable lateral support, enhancing overall stability during high-altitude operations and minimizing the risk of the insulated scaffolding device tipping over.

[0044] It should be noted that the insulating load-bearing module 30 has four insulating rods 31 arranged vertically. These four insulating rods 31 are arranged in a rectangular corner layout, and adjacent vertical insulating rods 31 are connected by horizontally arranged insulating rods 31, forming a stable rectangular frame structure. The transverse insulating rods 31 corresponding to the long side 302 of the rectangular frame are designed as foldable structures, facilitating folding along the long side 302 during transportation and storage, significantly reducing the overall volume and improving portability. The transverse insulating rods 31 corresponding to the short side 301, however, are fixed-length, non-foldable rigid structures. This design optimizes folding efficiency while ensuring structural strength and stability. Due to the larger size of the long side 302, the space compression effect from folding is more significant, maximizing the storage advantages of the folding structure. Simultaneously, keeping the short side 301 fixed minimizes the structural complexity and potential failure risks associated with multi-point folding, simplifies the design of the connection nodes 32, and improves overall rigidity and assembly reliability.

[0045] It should be noted that the connecting node 32 is a snap-fit, used to achieve a detachable connection between the insulating rods 31. It supports operation by hand or with simple tools, requiring no complex fastening equipment, facilitating work at heights or in confined spaces. The snap-fit ​​includes a protruding buckle at the end of the insulating rod 31 and a corresponding slot on the insulating rod 31. The protruding buckle is a hook-shaped structure with a beveled guide section and a locking shoulder, and the slot is a matching concave cavity. During connection, the protruding buckle is aligned with the slot and pushed in. The beveled guide section compresses and deforms the protruding buckle, and it springs back after passing the slot entrance. The shoulder engages and locks with the inner edge of the slot, achieving a quick connection between the insulating rods 31.

[0046] It should be noted that the base 10 is provided with a connecting shaft 11, and the end of the vertical insulating rod 31 of the bottom insulating support module 30 is provided with a connecting hole. By aligning the connecting hole and inserting it into the connecting shaft 11 on the base 10, the two can be connected by plugging. The module and the base 10 can be quickly assembled and disassembled without additional fasteners, which is convenient for rapid on-site deployment and transportation and storage, while ensuring the stability and centering of the connection.

[0047] The pole attachment mechanism 20 includes a clamp 21, a first connecting rod 22, and a second connecting rod 23. One end of the first connecting rod 22 and one end of the second connecting rod 23 are respectively connected to the two sides of a foldable or telescopic lateral side. The other ends of the first connecting rod 22 and the second connecting rod 23 are hinged to the clamp 21. When the pole attachment mechanism 20 is installed on the pole 60 and unfolded, the first connecting rod 22, the second connecting rod 23, and the two ends of the lateral side form a triangular support structure, restricting the relative movement of the lateral side. Utilizing the principle of geometric invariance, a rigid support system is constructed between the scaffolding platform and the pole 60, effectively restricting the relative movement of the lateral side in the extended state and preventing it from shrinking or deforming due to force, thereby ensuring the width stability and structural reliability of the working platform as much as possible. Simultaneously, this linkage structure automatically tensions during unfolding, achieving self-stabilization without the need for additional locking devices, making operation simple and responsive. The hinged connection method allows each component to flexibly adapt to the curvature of poles 60 of different diameters, improving the versatility and fit of the device. The pole attachment mechanism 20 works in conjunction with the foldable lateral side: when folded, the first link 22 and the second link 23 can be folded synchronously with the lateral side without increasing the storage volume; when unfolded, they automatically form a constraint, realizing the function of being fixed when unfolded, taking into account both portability and operational safety.

[0048] The clamp 21 consists of a body 211, a tensioner 212, and a hook 213. The body 211 is semi-circular and rests against the surface of the concrete pole. Tensioners 212 and hooks 213 are located at its two ends. The middle of the body 211 is hinged to the first connecting rod 22 and the second connecting rod 23, enabling linkage with the main body of the insulated scaffolding. The tensioner 212 is located at one end of the body 211 and contains a retractable nylon strap 214. In use, the nylon strap 214 is pulled to wrap around the concrete pole, and the end of the strap is fastened to the hook 213 at the other end. Tightening and locking securely fix the clamp 21. Because the length of the nylon strap 214 is adjustable, this structure can adapt to concrete poles of different diameters, ensuring a tight fit and stable fixation under various pole diameter conditions, thus improving the versatility and on-site applicability of the device.

[0049] To enhance the structural strength of the insulated scaffolding device, foldable or retractable diagonal braces 33 are provided between adjacent insulated load-bearing modules 30. The two ends of the diagonal braces 33 are detachably connected to the lateral sides of adjacent insulated load-bearing modules 30. This not only strengthens the overall structural integrity but also significantly improves the stability and safety of the scaffolding. When unfolded, the diagonal braces 33 form diagonal supports, effectively increasing the connection stiffness between the insulated load-bearing modules 30, suppressing swaying and lateral deformation of the multi-layered structure during high-altitude operations, and enhancing anti-overturning capabilities. Together with the side pole attachment mechanism 20, they form a dual stability system of lateral fixation and diagonal reinforcement. Furthermore, the diagonal braces 33 feature a foldable or retractable design, which, combined with the folding function of the insulated load-bearing modules 30 themselves, allows for simultaneous folding during disassembly or retraction without increasing storage volume, maintaining the overall portability and ease of transportation of the device, and balancing structural reinforcement with rapid assembly and disassembly requirements.

[0050] It should be noted that the diagonal bracing rod 33 should not be placed on the foldable lateral side, i.e., on the long side 302 of the rectangular frame, to avoid force interference or structural jamming caused by lateral folding movement. To ensure smooth folding, the diagonal bracing rod 33 can be selectively placed between the lateral insulating rods 31 on the short side 301, or connected to the vertically arranged insulating rods 31. When placed on the short side 301, it can form diagonal support in that direction, enhancing the overall rigidity of the rectangular frame and suppressing lateral and torsional deformation; when connected between the vertical insulating rods 31, it can effectively improve the module's resistance to lateral displacement and buckling in the vertical direction, improving the overall stability after multi-layer splicing.

[0051] For ease of use, the diagonal brace 33 is positioned on the same lateral side as the foldable or retractable side, allowing it to fold or extend synchronously with the lateral side. This achieves an integrated design between the diagonal brace 33 and the lateral side of the insulating load-bearing module 30 in terms of movement trajectory, enabling the diagonal brace 33 to fold synchronously with the side structure when retracted and extend synchronously when unfolded, eliminating the need for separate operation, simplifying the assembly and disassembly process, and improving work efficiency. The highly coordinated structure minimizes interference between the diagonal brace 33 and other components during the folding process, ensuring smooth operation and accurate positioning.

[0052] The insulating load-bearing module 30 features two sets of diagonal braces 33 positioned between its two opposing transverse sides, with the two sets of braces 33 arranged in opposite directions in a crisscross pattern. Compared to single-sided or unidirectional diagonal bracing, this crisscross arrangement results in more even stress distribution, stronger overall stability, and significantly improved safety margins for the aerial work platform. Furthermore, while ensuring high-strength support, the structure can still maintain its compactness and portability by designing the diagonal braces 33 to be foldable or retractable, allowing them to be folded in sync with the transverse sides.

[0053] It should be noted that both ends of the diagonal brace 33 are also detachably connected to the insulating rod 31 via connecting nodes 32. During scaffold assembly, the diagonal brace 33 can be installed on the ground simultaneously with other modules, reducing high-altitude operation steps; during transportation or storage, it can be disassembled as a whole or in sections to further reduce its size and improve portability.

[0054] Specifically, both the diagonal brace 33 and the insulating rod 31 on the lateral side include a first rod 331, a second rod 332, and a hinge 34 that connects the two and enables folding. This ensures that the diagonal brace 33 and the lateral side maintain the same folding mechanism, and the hinge 34 enables smooth folding and unfolding. The structure is simpler and the operation is more reliable.

[0055] The hinge 34 includes two connecting seats 341, a central shaft 342 passing through the connecting seats 341, and a torsion spring 343 sleeved on the central shaft 342. Each connecting seat 341 has a plug-in hole for quick plug-in connection with the first rod 331 or the second rod 332; one end of the two connecting seats 341 is hinged through the central shaft 342, forming a hinged structure that can rotate relative to each other. The torsion spring 343 is sleeved on the central shaft 342 and located between the two connecting seats 341, providing a continuous preload. When the diagonal brace 33 or the insulating rod 31 on the lateral side is unfolded from the folded state, the torsion spring 343 stores energy as the rotation angle increases, pushing the first rod 331 and the second rod 332 to automatically return to the fully unfolded direction. When the diagonal brace 33 is close to fully unfolded, approaching 180°, the free ends of the two connecting seats 341 abut against each other, forming a mechanical limiting structure to prevent further rotation and achieve self-locking. This limiting structure ensures the stability of the diagonal brace 33 in its extended state without additional locking devices, preventing loosening or accidental folding due to vibration or load, significantly improving operational safety. Simultaneously, this hinged structure allows for flexible angle adjustment of the diagonal brace 33 and the lateral insulating rod 31 within a range of 0° to 180°, adapting to different installation postures and space requirements, and is particularly convenient for rapid deployment in complex environments.

[0056] If the first rod 331 and the second rod 332 of the diagonal brace 33 are designed to be of equal length, the two ends will symmetrically converge towards the center during folding. This will cause the hinge point and the connecting nodes 32 at both ends to be too close in the later stage of folding, resulting in serious spatial conflict. Especially when approaching the fully folded state, it is easy to get stuck or unable to close, affecting the smoothness of operation and the compactness of the structure. To this end, in this application, the first rod 331 and the second rod 332 of the diagonal brace 33 are of different lengths, which can effectively stagger the movement trajectory of each component and the final convergence position during folding, avoid spatial interference between the hinge point, the rod and the connecting node 32, significantly reduce the risk of friction and collision, and make the folding action smoother and more reliable. At the same time, the long and short rod structure allows the shorter end to converge closer to the inside of the main frame, further compressing the overall envelope size and improving storage efficiency and portability.

[0057] To further enhance the reliability of the support, a side support mechanism 50 is connected to the lateral side of the insulating load-bearing module 30. The side support mechanism 50 includes a first support rod 51 and a second support rod 52. One end of the first support rod 51 can be supported on the ground, and the other end is hinged to one end of the second support rod 52. The other ends of the first support rod 51 and the second support rod 52 are detachably fixed to different connection positions on the lateral side to adjust the support angle. An adjustable diagonal brace is formed through the double-rod hinge structure. The first support rod 51 is directly on the ground, effectively transferring part of the vertical and lateral loads of the working platform to the ground, significantly improving the overall load-bearing capacity and anti-overturning performance of the scaffolding, especially suitable for soft or unevenly stressed working environments. The detachable connection method facilitates quick installation and disassembly. The side support mechanism 50 can be completely removed when not needed, without affecting module folding and transportation. By connecting the upper ends of the first support rod 51 and the second support rod 52 to different positions on the lateral side, the geometry of the support triangle can be flexibly adjusted, thereby adjusting the support angle. This allows the mechanism to adapt to different heights, distances, and ground slopes, enhancing on-site adaptability.

[0058] The system features detachable platform panels 40 along its transverse sides. These panels can be pre-installed on the folded transverse side frame as needed, and are ready for use once the module is fully unfolded. This minimizes the need for individual installation of the platform panels 40 at height, significantly improving installation efficiency and reducing the risk of falling objects. The detachable connection of the platform panels 40 facilitates disassembly, replacement, and maintenance, and also allows for easy storage during transport, reducing overall volume. Furthermore, the structure supports modular platform expansion, allowing for flexible configuration of single or multiple platform panels 40 to adapt to different work spaces. The platform panels 40 utilize composite hollow panels, effectively reducing weight and improving work efficiency while maintaining load-bearing capacity. The product's weight is minimized to ensure safety and strength, with each platform step not exceeding 15 kg. The height between each layer of platform panels 40 does not exceed 2 meters to facilitate assembly and disassembly. Each individual platform panel 40 has a working load ≥250 kg, with no more than 15 mm of platform panel subsidence, and the overall platform working load ≥500 kg. The static load strength test should be no less than 750 kg for 30 minutes, and no damage should be found in any of the components.

[0059] Furthermore, the connection node 32 includes a first claw 35 and a second claw 36 disposed at the end of the insulating rod 31. The first claw 35 is located outside the second claw 36 and has a greater range of rotation than the second claw 36. The second claw 36 has a first position for attaching other insulating rods 31 and a second position for being pushed by the first claw 35 to flip to avoid other insulating rods 31 when the first claw 35 rotates toward the second claw 36.

[0060] During installation, simply press down the insulating rod 31 and then lift it slightly. The second gripper 36 will automatically lock onto the horizontal insulating rod 31, achieving quick fixation. For height adjustment, simply push the other insulating rods 31 downwards to rotate the second gripper 36, then push the insulating rod 31 upwards. The first gripper 35 will rotate due to the horizontal insulating rod 31's movement. During this rotation, the first gripper 35 pushes the second gripper 36 to flip and disengage, allowing it to smoothly pass over other insulating rods 31, achieving interference-free lifting. Especially when a platform plate 40 is installed on the insulating rod 31, there is no need to flip the platform plate 40, and items placed on the platform plate 40 do not need to be stored; the platform plate 40 can be raised and lowered directly. The entire process requires no disassembly, flipping, or additional operation of the insulating rods 31, significantly improving work efficiency and site adaptability.

[0061] The first gripper 35 and the second gripper 36 are respectively hinged to the ends of the insulating rod 31 via a first pivot and a second pivot, and are respectively equipped with a first elastic element and a second elastic element to achieve stable holding in a predetermined position. The first gripper 35 is rotatably connected to the insulating rod 31 via the first pivot and has a rotational stroke of more than 180° about the first pivot. The first elastic element, such as a torsion spring or a tension spring, acts between the first gripper 35 and the insulating rod 31, applying an elastic restoring force to it, so that it tends to be held in a position separated from the second gripper 36 when no external force is applied. This position corresponds to the locking position in which it contacts and guides other insulating rods 31 during installation. The second gripper 36 is hinged to the insulating rod 31 via a second pivot, and its rotation range is limited by a limiting structure to a first position and a second position. The second elastic element is provided at the second pivot, applying an elastic preload to the second gripper 36, so that it is stably held in the first position under normal conditions, ensuring reliable locking of other insulating rods 31.

[0062] For ease of use, it can also be installed on a ladder so that users can climb it.

[0063] Understandably, in other embodiments, the insulating rods on all four lateral sides of the insulating load-bearing module are foldable, further enhancing the structural symmetry and spatial adaptability of the device. This allows the scaffolding platform to be folded in all four directions (front, back, left, and right), achieving omnidirectional folding. Compared to structures that are foldable on only one or both sides, the four-sided foldable design forms a more compact and orderly three-dimensional envelope after folding, significantly reducing the overall space occupied and greatly improving transportation and storage efficiency. It is particularly suitable for work scenarios where space is limited or requires dense vehicle storage.

[0064] Understandably, in other embodiments, the insulating pole can also employ a telescopic structure, for example, by sliding inner and outer sleeves supplemented with limit pins, snap rings, or locking knobs to achieve length adjustment and fixation. This design allows for continuous or graded adjustment of lateral or vertical dimensions without altering the overall pole layout, further enhancing the scaffolding platform's adaptability to different working spaces. Compared to a pure folding structure, the telescopic design allows for extension and retraction without significantly changing the pole angles, minimizing stress concentration issues associated with folding hinges under complex working conditions, simplifying the movement trajectory, reducing the number of hinged components, and improving structural reliability and maintenance convenience.

[0065] Understandably, in other embodiments, the connection node is a pin-type connector, which consists of an alignment hole at the end of the insulating rod and an insertable pin. During installation, the two insulating rods are joined together, aligning the connection holes at the ends, and then the pin is inserted and locked with a cotter pin or snap ring to prevent it from falling off. Disassembly and assembly can be completed without additional tools, making it particularly suitable for rapid assembly in high-altitude or space-constrained environments.

[0066] Understandably, in other embodiments, the connection node is a threaded joint, which uses internal and external threads to achieve the connection. Typically, an external thread is provided at the end of one insulating rod, and an internal thread sleeve is provided at the end of the other insulating rod. The connection is achieved by rotating and tightening, and disassembly and assembly can be completed without additional tools.

[0067] Understandably, in other embodiments, the connection node is a quick-connect coupling, commonly including spring pins, snap ring couplings, or push-lock buckles. Its working principle is that after the insulating rod is inserted into the coupling, the internal elastic element automatically pops out and snaps into the positioning groove, achieving quick fixation with a simple insertion and locking. Disassembly is easy; simply press the release button or pull the unlocking ring to separate. Operation is convenient, supports one-handed operation, significantly improves assembly efficiency, and is suitable for modular connection parts that require frequent disassembly and reassembly.

[0068] Understandably, in other embodiments, the connection node is a flange connection plate, which consists of two metal or high-strength composite material discs or square discs with bolt holes, respectively fixed to the ends of two insulating rods, and the two discs are fastened together by bolts. It has high connection rigidity and load-bearing capacity, and can effectively transmit complex loads.

[0069] In addition to the preferred embodiments described above, the present invention has other embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection claimed by the present invention.
