Description

Technical Field

[0001] This invention relates to the field of high-altitude operations technology, specifically to a lattice tower high-altitude operation platform and its installation method. Background Technology

[0002] In recent years, with the continuous development of wind power technology and the increasing emphasis on the construction efficiency and operational safety of wind power projects, the structural forms of wind turbine towers have gradually become more diversified. Among them, lattice towers have been widely used in many wind power projects in China due to their superior load-bearing capacity compared to traditional steel and reinforced concrete towers, as well as their advantages such as high structural safety, excellent seismic performance, low operating noise, and adaptability to terrain crossing ditches.

[0003] Lattice towers are typically assembled on-site section by section from multiple tower sections. Their main structure includes corner columns, diagonal braces, and horizontal struts. During equipment installation and subsequent operation and maintenance, high-altitude operations such as tightening corner column flange bolts and applying flange sealant are often required at the tower's height. However, currently, corner columns are mostly equipped only with foot spikes. Workers must stand on these small and unstable spikes for extended periods, easily leading to fatigue, operational instability, and significant safety hazards.

[0004] To improve safety during high-altitude operations, some companies use suspended platforms in conjunction with hoisting machinery. However, this approach requires the long-term use of cranes or similar equipment to assist in platform movement, increasing construction costs, reducing equipment utilization, and exacerbating operational risks in adverse weather conditions such as strong winds, rain, or snow, where the lack of effective temporary safety measures further aggravates the risks. Furthermore, the varying dimensional parameters of the corner columns of lattice towers across different wind power projects necessitate increased tooling investment if the work platform or auxiliary devices are not universally compatible, hindering both construction economics and project management efficiency.

[0023] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0024] Reference Figure 1 , Figure 2, Figure 3 and Figure 4 As shown, in a first aspect of the invention, the invention provides a lattice tower high-altitude operating platform suitable for installation and connection with a corner column 1, comprising: a fixed base 3, a standing platform 2, and a pressure plate 4; the fixed base 3 is disposed on the outer periphery of the corner column 1; the standing platform 2 includes a bottom frame 21 and a platform plate 22, the platform plate 22 is fixedly disposed on the bottom frame 21, the bottom frame 21 is slidably connected to the fixed base 3, and the platform plate 22 is provided with a clearance groove 221 at a position relative to the fixed base 3; the pressure plate 4 passes through the clearance groove 221 to be suitable for fixing the bottom frame 21 to the fixed base 3, the pressure plate 4 can slide in the vertical direction and is connected to the fixed base 3, and the pressure plate 4 can slide on the bottom frame 21.

[0025] Specifically, by setting a fixed base 3 on the outer periphery of the corner column 1, the operating platform can be reliably installed on the corner column 1 of the lattice tower. The bottom frame 21 of the platform 2 is slidably connected to the fixed base 3. The pressure plate 4 can be slidably set in the vertical direction to pass through the clearance groove 221 of the platform plate 22, fixing the bottom frame 21 to the fixed base 3. The setting of the pressure plate 4 makes the platform more flexible in the installation and disassembly process, and can quickly achieve positioning and fixation. The pressure plate 4 can slide on the bottom frame 21 to adjust the position according to corner columns of different diameters, effectively improving construction efficiency. In addition, by pressing and fixing the bottom frame 21 with the pressure plate 4 passing through the clearance groove 221, the stability of the entire platform during high-altitude operations can be enhanced, avoiding loosening or displacement caused by external factors such as vibration or wind, and ensuring the safety of operators. The platform structure of this invention is simple, the components are highly versatile, it can be applied to corner columns of different diameters, it is easy to mass-produce and assemble on site, and it is easy to maintain, which can effectively reduce construction and maintenance costs and improve overall economy.

[0026] In a first aspect of the present invention, the outer wall of the corner post 1 is provided with a connecting seat, and the fixed base 3 is provided with a connecting post 33 on the side facing the corner post 1. The connecting post 33 is inserted into the connecting seat so that the fixed base 3 is fixed on the corner post 1.

[0027] Furthermore, by setting a connecting seat on the outer wall of the corner column 1 and setting a connecting post 33 on the side of the fixed base 3 facing the corner column 1 for insertion, rapid positioning and stable connection between the fixed base 3 and the corner column 1 are achieved. This insertion structure simplifies the installation process, avoids the cumbersome procedures of traditional screwing or welding methods, not only shortens the construction time but also lowers the technical threshold for installation. At the same time, without affecting the strength of the main structure of the lattice tower, this structure ensures the overall stability and safety of the operating platform during high-altitude operations, further improving the reliability and practicality of the device in practical applications.

[0028] It is understandable that when the platform 2 tilts away from the corner post 1, the connecting post 33 can tilt towards the corner post 1 to abut against it, so that the corner post 1 can bear the load and improve reliability and safety.

[0029] Reference Figure 5 and Figure 6 As shown, in the first aspect embodiment of the present invention, the pressure plate 4 has a stepped structure, and the fixed base 3 is vertically connected to each other, including a horizontal part 32 and a vertical part 31. The pressure plate 4 is slidably disposed on the vertical part 31 to be suitable for fixing the bottom frame 21 on the horizontal part 32.

[0030] Furthermore, the pressure plate 4 adopts a stepped structure, which, together with the fixed base 3, consists of a horizontal part 32 and a vertical part 31 that are perpendicularly connected to each other. This allows the pressure plate 4 to slide along the vertical part 31 and effectively press the bottom frame 21 onto the horizontal part 32. This design not only improves the stress stability and assembly accuracy of the pressing structure, but also avoids loosening or slippage caused by uneven structural stress. At the same time, the stepped pressure plate 4 helps to achieve graded positioning and multi-point contact, enhancing the reliability of the pressing effect and effectively improving the overall load-bearing capacity and safety performance of the platform during high-altitude operations.

[0031] In a first aspect of the present invention, the vertical portion 31 is provided with a first waist-shaped hole 311 along the horizontal direction, and the pressure plate 4 is provided with a second waist-shaped hole 42 corresponding to the position of the first waist-shaped hole 311, the length direction of the second waist-shaped hole 42 being along the vertical direction.

[0032] Furthermore, by providing a first waist-shaped hole 311 extending in the horizontal direction on the vertical part 31 and a second waist-shaped hole 42 extending in the vertical direction on the pressure plate 4, the two form a cross-sliding fit structure when they are connected.

[0033] Understandably, this structural design not only facilitates fine-tuning and positioning of the pressure plate 4 during installation, improving assembly flexibility and tolerance adaptability, but also allows for precise adjustment of the pressure plate 4 at different positions according to actual needs, effectively improving the assembly efficiency and installation accuracy of the fixed structure. Furthermore, this cross-sliding structure helps alleviate stress concentration at the connection points caused by dimensional errors or thermal expansion and contraction, further enhancing the structural stability and durability of the platform during use.

[0034] In a first aspect embodiment of the present invention, a third waist-shaped hole 321 is provided on the horizontal part 32, and a fourth waist-shaped hole 41 is provided on the pressure plate part 4 corresponding to the position of the third waist-shaped hole 321. The length directions of the third waist-shaped hole 321 and the fourth waist-shaped hole 41 are both arranged in the horizontal direction.

[0035] Furthermore, a third oblong hole 321 extending horizontally along the length direction is provided on the horizontal part 32, and a fourth oblong hole 41 extending horizontally at the corresponding position is provided on the pressure plate 4. This provides a larger lateral adjustment range during fixed connection, which is beneficial for fine-tuning the relative position between the bottom frame 21 and the fixed base 3 during installation, improving assembly flexibility. In addition, this design can effectively overcome the influence of processing or installation errors on the overall structural positioning accuracy, ensuring that the clamping structure can achieve reliable clamping and fixing under different working conditions, further enhancing the stability and safety of the aerial work platform, while also helping to improve the adaptability and versatility of the overall structure.

[0036] In a first aspect of the present invention, a pad 5 is provided between the fixed base 3 and the bottom frame 21. The pad 5 is provided with a fifth waist-shaped hole at the position corresponding to the third waist-shaped hole 321. The length direction of the fifth waist-shaped hole is arranged in the horizontal direction and is perpendicular to the length direction of the third waist-shaped hole 321.

[0037] Specifically, by adding a pad 5 between the fixed base 3 and the bottom frame 21, and setting a fifth waist-shaped hole in the horizontal direction on the pad 5, and the fifth waist-shaped hole being perpendicular to the length direction of the third waist-shaped hole 321, a multi-layered, staggered waist-shaped hole structure is formed, which effectively improves the adjustment capability of the connection structure in multiple directions.

[0038] Understandably, this design not only enhances the dimensional adaptability and structural flexibility of the aerial work platform during installation, but also absorbs or mitigates stress concentration caused by structural deformation, thermal expansion and contraction, or external impacts to a certain extent, thereby improving the platform's overall resistance to deformation and its service life. Simultaneously, the pad 5 acts as a transition buffer during the clamping process, further improving the stress conditions of the pressure plate 4 and enhancing the long-term stability and safety of the connection points.

[0039] In a first aspect embodiment of the present invention, multiple fixed bases 3 and pressure plates 4 are provided, and the number of fixed bases 3 and pressure plates 4 is the same.

[0040] Specifically, by setting multiple fixed bases 3 and pressure plates 4, and ensuring that their numbers are consistent, a multi-point arrangement and multi-point clamping structural layout is achieved, effectively improving the overall stress balance and structural stability of the aerial work platform during installation. The multiple sets of fixing units also have a certain degree of redundancy; even if some connection parts are damaged due to external forces or fatigue, other connection points can still maintain structural stability, improving the overall safety and reliability of the device.

[0041] In a first aspect of the present invention, the platform 2 further includes guardrails 23, which are disposed on the side of the platform 22 away from the fixed base 3.

[0042] Specifically, by installing guardrails 23 on the platform 2 and placing them on the side of the platform 22 away from the fixed base 3, effective lateral protection can be provided when workers stand on the platform to perform high-altitude operations, preventing personnel from accidentally stepping on or falling, and significantly improving work safety.

[0043] In a first aspect of the present invention, the platform plate 22 is provided with connecting lugs 24.

[0044] Specifically, by providing connecting lugs 24 on the platform plate 22, the aerial work platform gains convenient hoisting and handling capabilities. This facilitates rapid lifting, moving, and positioning of the platform on the construction site using cranes and other equipment, significantly improving construction efficiency. The connecting lugs 24 have a simple structure and reliable strength, and their arrangement can be optimized according to the platform's weight and the working environment, ensuring safety and stability during high-altitude transportation. Simultaneously, the connecting lugs 24 also facilitate the storage and transportation of the platform when not in operation, further enhancing the ease of use and engineering adaptability of this invention.

[0045] The second invention also provides a method for installing a high-altitude operating platform for a lattice tower, comprising: Temporarily fasten the platform 2, the fixed base 3 and the pressure plate 4; Measure the circumferential distance parameters of the connecting seat on the outer wall of the corner column 1. Based on the circumferential distance parameters, adjust the spacing of each fixed base 3, and then fix the platform 2, fixed base 3 and pressure plate 4 together. The high-altitude operating platform of the lattice tower is hoisted so that the connecting column 33 can be inserted into the connecting seat; Use connecting steel cables to connect the connecting lug 24 to the fixed point of the corner post 1.

[0046] Specifically, the installation method provided by the present invention first temporarily tightens the platform 2, the fixed base 3 and the pressure plate 4, and then adjusts the spacing of the fixed base 3 based on the measured circumferential distance parameter of the connecting seat on the outer wall of the corner column 1, so as to ensure the accurate alignment and structural symmetry of each connection part, and effectively improve the accuracy and stability of the platform installation.

[0047] The use of a hoisting method allows for quick connection between the connecting column 33 and the connecting seat, simplifying the installation process, shortening operation time, and significantly improving construction efficiency. Furthermore, by using connecting steel cables to connect the platform's connecting lug 24 to the corner column 1 fixing point, not only is the overall connection strength between the platform and the tower enhanced, but the resistance to wind loads and vibrations is also improved, ensuring the long-term safe and reliable operation of the platform in high-altitude working environments. This method has clear operating steps, strong on-site adaptability, facilitates standardized operations, and has good engineering application value.
