Description

Technical Field

[0001] The utility model relates to a working platform, in particular to a working platform for a boiler spiral water-cooled wall. Background Art

[0002] The boiler's spiral water-cooled wall is huge, with a total height of more than 30 meters. It needs to be connected in the air on site and assembled in sections. The construction of the water-cooled wall requires an aerial work platform, and the operator stands on the aerial work platform to operate and realize the connection, welding and sealing of the water-cooled wall pipes.

[0003] Since the cooling water pipes on the spiral water-cooled wall of the boiler are inclined, it is not convenient to fix the aerial work platform, and scaffolding needs to be erected from the ground, which is troublesome and costly. Utility Model Content

[0004] The technical problem to be solved and the technical task proposed by the utility model are to improve and perfect the existing technical solutions, and provide a working platform for the spiral water-cooled wall of the boiler to facilitate the erection of the working platform and improve the working efficiency. To this end, the utility model adopts the following technical solutions.

[0005] A working platform for a boiler spiral water-cooled wall comprises a platform and a platform connecting portion, wherein the platform connecting portion comprises two base plates located at the front end portions on the left and right sides of the platform, and two parallel through-wall plates arranged on the base plates, wherein the base plates are arranged vertically, and the through-wall plates are arranged perpendicularly in front of the base plates and inclined to the working surface of the platform, and the inclination of the through-wall plates and the distance between two adjacent through-wall plates match the cooling pipes of the boiler spiral water-cooled wall.

[0006] The boiler spiral water-cooled wall is welded in sequence by cooling water pipes, fins, cooling water pipes, fins, etc.

[0007] The inclination angle of the wall panel is consistent with that of the spiral water-cooled wall, and the spacing between the two through-wall panels is determined according to the spacing between the spiral water-cooled wall tubes. The through-wall panel passes through the fin gap of the boiler spiral water-cooled wall to achieve the connection between the through-wall panel and the spiral water-cooled wall, so that the platform can be horizontally set on the inclined spiral water-cooled wall.

[0008] Since the inclination of the through-wall plate is consistent with the inclination angle of the boiler spiral water-cooled wall, it ensures that the platform can fit tightly on the spiral water-cooled wall, providing a stable working platform. The spacing between the two through-wall plates is determined according to the spacing of the spiral water-cooled wall tubes. The through-wall plate can pass through the fin gap to achieve connection with the spiral water-cooled wall, further enhancing the stability of the platform. Due to the design of the platform connection part, the platform can be horizontally set on the inclined spiral water-cooled wall, avoiding the instability problem of traditional scaffolding during high-altitude operations. The design of the platform connection part makes the installation and disassembly of the platform simple and quick, and improves work efficiency. The platform workstation surface is horizontal, providing a comfortable working environment for the operator and reducing fatigue caused by long-term work. The connection between the platform and the spiral water-cooled wall is firm, reducing the possibility of platform sliding or shaking, and ensuring the safety of the operation. The connection method between the through-wall plate and the fin gap avoids the risk of loose erection or installation errors that may exist in traditional scaffolding. The platform has a simple structure, does not require complex structures and expensive materials, and reduces manufacturing costs. The platform can be reused, reducing resource waste and improving economic benefits. This technical solution is easy to erect and is conducive to improving work efficiency.

[0009] In order to improve the strength of the connection, a connecting piece, such as a clamp, a latch, a clamp, etc., can be added to the end of the penetration plate to close the opening between two adjacent penetration plates.

[0010] As a preferred technical means: relative through holes are opened on two adjacent penetration plates, the height of the penetration plates is greater than the thickness of the boiler spiral water-cooled wall, the penetration plates pass through the boiler spiral water-cooled wall until the through holes are exposed on the back side of the boiler spiral water-cooled wall, bolts pass through the through holes and are fixed with nuts to fix the platform on the boiler spiral water-cooled wall.

[0011] By opening relative through holes on the penetration plate and fixing the platform to the boiler spiral water-cooled wall with bolts and nuts, this connection method greatly enhances the stability of the platform. Even in harsh working environments, it can ensure that the platform will not shake or move, ensuring the safety of the staff. The installation method of bolts and nuts is simple and quick, without the need for complex tools or skills, making the installation process of the platform more efficient. At the same time, since the height of the penetration plate is greater than the thickness of the boiler spiral water-cooled wall, the penetration plate can easily pass through the water-cooled wall, making the installation process easier. Bolt and nut connection is a mature and reliable connection method with high strength and durability. This connection method can ensure that the platform remains stable during long-term use without loosening or falling off. If the platform needs to be disassembled or moved, it can be easily achieved by simply loosening the bolts and nuts. This design makes the maintenance of the platform more convenient and reduces maintenance costs and time.

[0012] As a preferred technical means: the platform includes support frames located on the left and right sides and a table plate located between the two support frames, and the front end of the support frame is provided with the base plate.

[0013] As the main load-bearing structure of the platform, the support frame can bear a large load, ensuring the stability and safety of the platform during installation, maintenance or daily inspection. The combined design of the support frame and the base plate makes the installation of the platform simple and quick. The staff can quickly build or dismantle the platform as needed, which improves work efficiency. The platform between the two support frames provides a spacious operating space for the staff, allowing them to move and operate freely on the platform, improving work efficiency and comfort.

[0014] As a preferred technical means: the base plate and the support frame are fixedly connected, and the table top and the support frame are detachably connected.

[0015] The fixed connection between the base plate and the support frame ensures the overall stability of the platform structure and can reduce the safety hazards caused by loose or deformed structure during work. The detachable connection between the table plate and the support frame makes the construction and disassembly process of the platform simple and quick. When the platform needs to be built, the table plate can be quickly installed on the support frame; when it is not needed, the table plate can also be easily disassembled for storage or transportation. Due to the detachable connection between the table plate and the support frame, the size, number or layout of the table plate can be adjusted according to specific work needs, so that the platform can adapt to different work scenes and operation requirements. If the table plate is damaged or worn, it can be disassembled and replaced with a new one separately without replacing the entire platform, which reduces maintenance costs and extends the service life of the platform. The fixedly connected base plate ensures the stability of the bottom structure of the platform, thereby improving the safety of the entire platform. The detachable table plate can be easily stacked and stored after disassembly, which reduces the storage space occupied and makes the platform more convenient and flexible during transportation.

[0016] As a preferred technical means: the support frame is provided with a positioning hole, and the left and right ends of the table plate are provided with positioning hooks, and the positioning hooks of the table plate are inserted downward into the positioning holes of the support frame to fix the table plate.

[0017] The tabletop is directly connected to the positioning hole of the support frame through the positioning hook, without the need for additional fixing tools or materials, which greatly simplifies the installation process and improves work efficiency. When the tabletop needs to be disassembled or moved, just gently lift the tabletop to disengage its positioning hook from the positioning hole. There is no need for complicated disassembly steps, which is convenient and quick. The cooperation between the positioning hook and the positioning hole can ensure that the tabletop is firmly fixed on the support frame, reducing the safety hazards caused by the shaking or displacement of the tabletop during work. The design of the positioning hole and positioning hook can ensure the accurate position of the tabletop on the support frame, ensure the flatness and stability of the working platform, and improve work accuracy and safety.

[0018] As a preferred technical means: the support frame is provided with positioning holes arranged side by side on the left and right sides, so that the left and right table plates share a support frame to realize the splicing of the table plates in the left and right directions.

[0019] Through the positioning holes set side by side on the left and right, the left and right platforms can be closely spliced ​​together and share the same support frame, which not only saves the number of support frames used, but also improves space utilization and makes the entire platform structure more compact. The design of the shared support frame forms a stable connection between the left and right platforms, which helps to reduce the shaking and displacement of the platform during work and improves work accuracy and safety. By adjusting the position and number of positioning holes, it can adapt to the splicing needs of platforms of different sizes and shapes, making the platform more versatile and flexible, and able to adapt to different work scenarios and operation requirements.

[0020] As a preferred technical means: the support frame is provided with positioning holes arranged side by side in front and back, so that the table boards share a support frame to achieve splicing of the table boards in the front and back directions.

[0021] Through the positioning holes arranged side by side in the front and back, the table tops can be spliced ​​in the front and back directions, thereby increasing the width or area of ​​the platform, so that the platform can be flexibly expanded according to specific work needs to meet the requirements of work areas of different sizes and shapes.

[0022] As a preferred technical means: a vertical column is provided at the rear end of the support frame, and a horizontal railing is provided between the left and right columns.

[0023] The vertical columns provide additional vertical support for the entire support frame, enhancing the structural stability of the support frame, ensuring that the platform is more stable when subjected to vertical loads, and reducing safety risks caused by shaking or tilting. The horizontal railing is set between the left and right columns to provide a safety barrier for workers, effectively preventing workers from accidentally falling when working on the platform, and improving work safety. The role of the railing is particularly important, especially in high-altitude operations or harsh environments. The design of the vertical columns and horizontal railings makes the installation and removal process relatively simple. Operators can quickly install or remove the railings as needed to adapt to different work scenarios and needs.

[0024] As a preferred technical means: the support frame and the column are detachably connected.

[0025] The detachable connection makes the installation and removal of the support frame and the column simple and quick. This can greatly reduce the time and labor costs required to build and dismantle the platform, and improve work efficiency. Since the support frame and the column can be disassembled and separated, the transportation and storage methods can be selected more flexibly, reducing transportation and storage costs, especially when the platform needs to be transferred from one work site to another.

[0026] As a preferred technical means: a connecting ring for connecting a rope is provided on the handrail or the column. The rope can be used to lift the working platform, and in addition, the extended end of the working platform can be suspended by the rope.

[0027] The connecting ring provides a secure attachment point for the rope, allowing the work platform to be easily lifted and moved by the rope, simplifying the platform handling process and improving work efficiency, especially when the platform needs to be moved frequently or transferred between different locations. When using a rope to lift the platform, the connecting ring can ensure that the connection between the rope and the work platform is secure and reliable, reducing the safety risks caused by rope sliding or falling off. At the same time, during the lifting process, the connecting ring can also play a role in balance and stability, further ensuring the safety of the staff. The design of the connecting ring not only enhances the lifting safety of the platform, but also enhances the overall stability of the platform during use, further fixes the platform structure, and reduces shaking or displacement caused by external forces.

[0028] Beneficial effects: Since the inclination of the through-wall plate is consistent with the inclination angle of the boiler spiral water-cooled wall, it ensures that the platform can fit tightly on the spiral water-cooled wall, providing a stable working platform. The spacing between the two through-wall plates is determined according to the spacing of the spiral water-cooled wall tubes. The through-wall plate can pass through the fin gap to achieve connection with the spiral water-cooled wall, further enhancing the stability of the platform. Due to the design of the platform connection part, the platform can be horizontally set on the inclined spiral water-cooled wall, avoiding the instability problem of traditional scaffolding during high-altitude operations. The design of the platform connection part makes the installation and disassembly of the platform simple and quick, and improves work efficiency. The platform workstation surface is horizontal, providing a comfortable working environment for the operator and reducing fatigue caused by long-term work. The connection between the platform and the spiral water-cooled wall is firm, reducing the possibility of platform sliding or shaking, and ensuring the safety of the operation. The connection between the through-wall plate and the fin gap avoids the risk of loose erection or wrong installation of traditional scaffolding. The platform has a simple structure, does not require complex structures and expensive materials, and reduces manufacturing costs. The platform can be reused, reducing resource waste and improving economic benefits. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The technical solution of the utility model is further described in detail below in conjunction with the accompanying drawings of the specification.

[0039] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Since the embodiments disclosed in the present invention can be set in different directions, these terms indicating directions are only for illustration and should not be regarded as limitations. For example, "up" and "down" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0040] like Figure 1 , 2 As shown, the utility model includes a platform and a platform connecting part, the platform connecting part includes two base plates 1 located at the front ends of the left and right sides of the platform, and two parallel through-wall plates 2 arranged on the base plates 1. The base plates 1 are arranged vertically, and the through-wall plates 2 are vertically arranged in front of the base plates 1 and inclined to the working standing surface of the platform. The inclination of the through-wall plates 2 and the distance between two adjacent through-wall plates 2 match the cooling pipes 4 of the spiral water-cooled wall 3 of the boiler.

[0041] like Figure 3 , 4 As shown, the boiler spiral water-cooled wall 3 is welded in sequence by cooling water pipes, fins, cooling water pipes, fins, etc.;

[0042] The inclination angle of the wall plate is consistent with that of the spiral water-cooled wall, and the spacing between the two through-wall plates 2 is determined according to the spacing of the spiral water-cooled wall tubes. The through-wall plate 2 passes through the fin gap of the boiler spiral water-cooled wall 3 to achieve the connection between the through-wall plate 2 and the spiral water-cooled wall, so that the platform can be horizontally set on the inclined spiral water-cooled wall.

[0043] Since the inclination of the through-wall plate 2 is consistent with the inclination angle of the boiler spiral water-cooled wall 3, it ensures that the platform can fit tightly on the spiral water-cooled wall, providing a stable working platform. The spacing between the two through-wall plates 2 is determined according to the spacing of the spiral water-cooled wall tubes. The through-wall plate 2 can pass through the fin gap to achieve connection with the spiral water-cooled wall, further enhancing the stability of the platform. Due to the design of the platform connection part, the platform can be horizontally set on the inclined spiral water-cooled wall, avoiding the instability problem of traditional scaffolding during high-altitude operations. The design of the platform connection part makes the installation and disassembly of the platform simple and fast, and improves work efficiency. The platform workstation surface is horizontal, providing a comfortable working environment for the operator and reducing fatigue caused by long-term work. The connection between the platform and the spiral water-cooled wall is firm, reducing the possibility of platform sliding or shaking, and ensuring the safety of the operation. The connection method between the through-wall plate 2 and the fin gap avoids the risk of loose erection or wrong installation of traditional scaffolding. The platform has a simple structure, does not require complex structures and expensive materials, and reduces manufacturing costs. The platform can be reused, reducing resource waste and improving economic benefits.

[0044] In order to improve the load-bearing capacity, the platform includes support frames 8 located on the left and right sides and a table plate 9 located between the two support frames 8 . A base plate 1 is provided at the front end of the support frame 8 .

[0045] As the main load-bearing structure of the platform, the support frame 8 can bear a large load, and can ensure the stability and safety of the platform whether it is being installed, repaired or inspected daily. The combined design of the support frame 8 and the base plate 1 makes the installation of the platform simple and quick. The staff can quickly build or dismantle the platform as needed, which improves work efficiency. The table 9 located between the two support frames 8 provides a spacious operating space for the staff, allowing the staff to move and operate freely on the platform, improving work efficiency and comfort.

[0046] In order to take into account both the load-bearing capacity and the convenience of assembly and disassembly, the base plate 1 and the support frame 8 are fixedly connected, and the table top 9 and the support frame 8 are detachably connected.

[0047] The fixed connection between the base plate 1 and the support frame 8 ensures that the overall structure of the platform is stable, and can reduce the potential safety hazards caused by loose or deformed structures during work. The detachable connection between the table plate 9 and the support frame 8 makes the construction and disassembly process of the platform simple and quick. When the platform needs to be built, the table plate 9 can be quickly installed on the support frame 8; when it is not needed, the table plate 9 can also be easily disassembled for storage or transportation. Due to the detachable connection between the table plate 9 and the support frame 8, the size, quantity or layout of the table plate 9 can be adjusted according to specific work requirements, so that the platform can adapt to different work scenes and operation requirements. If the table plate 9 is damaged or worn, it can be disassembled and replaced with a new table plate 9 separately without replacing the entire platform, which reduces maintenance costs and extends the service life of the platform. The fixedly connected base plate 1 ensures the stability of the bottom structure of the platform, thereby improving the safety of the entire platform. The detachable table plate 9 can be easily stacked and stored after disassembly, which reduces the storage space occupied and makes the platform more convenient and flexible during transportation.

[0048] In order to achieve reliable connection of the table plate 9, the support frame 8 is provided with a positioning hole 10, and the left and right ends of the table plate 9 are provided with positioning hooks 11. The positioning hooks 11 of the table plate 9 are inserted downward into the positioning holes 10 of the support frame 8 to fix the table plate 9.

[0049] The table top 9 is directly inserted and connected to the positioning hole 10 of the support frame 8 through the positioning hook 11, without the need for additional fixing tools or materials, which greatly simplifies the installation process and improves work efficiency. When the table top 9 needs to be disassembled or moved, it is only necessary to gently lift the table top 9 to disengage its positioning hook 11 from the positioning hole 10. There is no need for complicated disassembly steps, which is convenient and quick. The cooperation between the positioning hook 11 and the positioning hole 10 can ensure that the table top 9 is firmly fixed on the support frame 8, reducing the safety hazards caused by the shaking or displacement of the table top 9 during work. The design of the positioning hole 10 and the positioning hook 11 can ensure the accurate position of the table top 9 on the support frame 8, ensure the flatness and stability of the working platform, and improve work accuracy and safety.

[0050] In order to improve the flexibility of use, a support frame 8 is provided with positioning holes 10 arranged side by side on the left and right, so that the left and right table boards 9 share a support frame 8 to realize the splicing of the table boards 9 in the left and right directions.

[0051] Through the positioning holes 10 arranged side by side on the left and right, the left and right platforms 9 can be tightly spliced ​​together and share the same support frame 8, which not only saves the number of support frames 8 used, but also improves space utilization and makes the entire platform structure more compact. The design of the shared support frame 8 forms a stable connection between the left and right platforms 9, which helps to reduce the shaking and displacement of the platform during work and improves work accuracy and safety. By adjusting the position and number of the positioning holes 10, it is possible to adapt to the splicing requirements of platforms 9 of different sizes and shapes, making the platform more versatile and flexible and able to adapt to different work scenarios and operating requirements.

[0052] In order to improve the safety of work, a vertical column 12 is provided at the rear end of the support frame 8, and a horizontal railing 13 is provided between the left and right columns 12.

[0053] The vertical columns 12 provide additional vertical support for the entire support frame 8, enhance the structural stability of the support frame 8, ensure that the platform is more stable when subjected to vertical loads, and reduce safety risks caused by shaking or tilting. The horizontal railing 13 is set between the left and right columns 12, providing a safety barrier for the staff, effectively preventing the staff from accidentally falling when working on the platform, and improving work safety. The role of the railing 13 is particularly important, especially in high-altitude operations or harsh environments. The design of the vertical columns 12 and the horizontal railing 13 makes the installation and disassembly process relatively simple, and the operator can quickly install or disassemble the railing 13 as needed to adapt to different work scenarios and needs.

[0054] For the convenience of transportation, the support frame 8 and the column 12 are detachably connected. The detachable connection can be screws or the like. To improve the reliability of the connection, a reinforcing rib can be provided at the connection between the support frame 8 and the column 12. Of course, the column 12 can also be "L" shaped, with a connection hole at the bottom, and the screw passes through the connection hole of the column 12 from top to bottom to connect with the support frame 8, thereby realizing the connection between the support frame 8 and the column 12.

[0055] The detachable connection makes the installation and removal process of the support frame 8 and the column 12 simple and quick. This can greatly reduce the time and labor cost required for building and disassembling the platform, and improve work efficiency. Since the support frame 8 and the column 12 can be detached and separated, the transportation method and storage method can be selected more flexibly, reducing the transportation and storage costs, especially when the platform needs to be transferred from one work site to another.

[0056] Embodiment 2:

[0057] like Figure 5 , 6As shown, in order to improve the strength of the connection, a connecting piece such as a clamp, a latch, a clamp, etc. can be added to the end of the penetration plate 2 to close the opening between two adjacent penetration plates 2.

[0058] In this embodiment, the connecting member is a bolt 6. Two adjacent through-holes 5 are provided on the two adjacent through-wall plates 2. The height of the through-wall plates 2 is greater than the thickness of the boiler spiral water-cooled wall 3. The through-wall plates 2 pass through the boiler spiral water-cooled wall 3 until the through-hole 5 is exposed on the back of the boiler spiral water-cooled wall 3. The bolt 6 passes through the through-hole 5 and is fixed by the nut 7, so that the platform is fixed on the boiler spiral water-cooled wall 3.

[0059] By opening relative through holes 5 on the penetration plate 2 and fixing the platform on the boiler spiral water-cooled wall 3 with bolts 6 and nuts 7, this connection method greatly enhances the stability of the platform, and ensures that the platform will not shake or move even in harsh working environments, thereby ensuring the safety of the staff. The installation method of bolts 6 and nuts 7 is simple and quick, and does not require complicated tools or skills, making the installation process of the platform more efficient. At the same time, since the height of the penetration plate 2 is greater than the thickness of the boiler spiral water-cooled wall 3, the penetration plate 2 can easily pass through the water-cooled wall, making the installation process easier. The connection of bolts 6 and nuts 7 is a mature and reliable connection method with high strength and durability. This connection method can ensure that the platform remains stable during long-term use without loosening or falling off. If the platform needs to be disassembled or moved, it can be easily achieved by simply loosening the bolts 6 and nuts 7. This design makes the maintenance of the platform more convenient and reduces maintenance costs and time.

[0060] Embodiment three:

[0061] like Figure 7 As shown, the same points as the first embodiment are not repeated here, the difference is that the support frame 8 is provided with a plurality of front and rear rows of positioning holes 10. In the present embodiment, one support frame 8 is provided with three front and rear rows of positioning holes 10, so that the table tops 9 share one support frame 8 to realize the splicing of two table tops 9 in the front and rear direction.

[0062] Through the positioning holes 10 arranged side by side in the front and back directions, the table tops 9 can be spliced ​​in the front and back directions, thereby increasing the width or area of ​​the platform, so that the platform can be flexibly expanded according to specific work needs to meet the requirements of work areas of different sizes and shapes.

[0063] Embodiment 4:

[0064] The same points as those in the third embodiment are not described in detail, except that:

[0065] For the convenience of hoisting and safety of use, a connecting ring 14 for connecting a rope is provided on the handrail 13 or on the column 12. The rope can be used to hoist the working platform, and in addition, the overhanging end of the working platform can also be suspended by the rope.

[0066] like Figure 8 As shown, in this embodiment, the connecting ring 14 is arranged at the top of the column 12. The connecting ring 14 provides a firm attachment point for the rope, so that the working platform can be easily lifted and moved by the rope, which simplifies the handling process of the platform and improves work efficiency, especially when the platform needs to be moved frequently or transferred between different locations. When the platform is lifted by rope, the connecting ring 14 can ensure that the connection between the rope and the working platform is firm and reliable, reducing the safety risks caused by rope sliding or falling off. At the same time, during the lifting process, the connecting ring 14 can also play a role of balance and stability, further ensuring the safety of the staff. The design of the connecting ring 14 not only enhances the lifting safety of the platform, but also enhances the overall stability during the use of the platform, further fixes the platform structure, and reduces the shaking or displacement caused by external forces.
