Abstract
Description
Technical Field
[0001] This utility model relates to the field of boiler membrane wall installation platforms, and in particular to a simple platform support for high-altitude connection of boiler membrane water-cooled wall pipes. Background Technology
[0002] In the installation of boiler membrane water-cooled walls, due to the long and heavy shape of the membrane water-cooled walls, they often need to be assembled in sections on the ground and then welded together at height. This necessitates a reliable and safe working platform for high-altitude welding operations. However, since the welding of membrane water-cooled walls requires work on both the inside and outside of the boiler, temporary fixed platforms or ladders are typically erected using scaffolding or large hoisting equipment. This results in complex structures, long construction periods, and high material consumption. Furthermore, these platforms often fail to provide reliable support to the membrane water-cooled wall fin structure, posing a risk of overturning. Therefore, such temporary platforms often increase construction costs and safety risks. Utility Model Content
[0003] The technical problem to be solved and the technical task proposed by this utility model is to improve and refine existing technical solutions, and to provide a simple platform support for high-altitude connection of boiler membrane water-cooled wall tubes, with the aim of simplifying the structure, reducing construction costs and improving safety. To this end, this utility model adopts the following technical solution.
[0004] A simple platform support for high-altitude connection of boiler membrane water-cooled wall tubes includes hooks, a frame, support components, guardrails, and guardrail fixing devices. The frame is formed from a single piece of round steel and includes a vertical long pole, a horizontal pole located on the lower left side of the vertical long pole, and a short vertical pole located on the upper left side of the horizontal pole. The hooks are located on the upper right side of the vertical long pole for hanging on the membrane water-cooled wall. The support components are located on the lower right side of the vertical long pole, and the support components have two symmetrical support points on the front and back of the frame for supporting the membrane wall tube fins. The short vertical pole is connected to and fixed to the guardrails through the guardrail fixing devices. The simple platform support can be easily attached to the membrane water-cooled wall using hooks. The support components form a stable support structure through two symmetrical support points and the hook connection points. By attaching multiple simple platform supports to the membrane water-cooled wall, and then laying planks on the horizontal bars of the simple platform supports to serve as standing and working platforms, and installing safety ropes on the guardrails, protection is provided for workers at height, ensuring high safety and effectively preventing accidental falls and guaranteeing operational safety. The support structure is simple in overall design, easy to manufacture, quick to construct, and inexpensive, enabling rapid assembly of simple platforms. The frame is made from a single piece of round steel, resulting in high strength.
[0005] As a preferred technical means, the upper end of the short vertical pole is integrally formed with a reinforcing connecting rod, which extends obliquely to the upper right from the upper end of the short vertical pole, and its top end is fixedly connected to the upper end of the long vertical pole. This can effectively enhance the structural strength of the frame, improve the deformation resistance of the entire frame when subjected to lateral forces or uneven loads, and make the support more stable and reliable.
[0006] As a preferred technical means: the upper end of the reinforcing connecting rod is provided with a vertical connecting rod, which is attached to the upper left side of the vertical rod and the two are fixed by welding. This effectively enhances the connection strength between the reinforcing connecting rod and the vertical connecting rod. This welded connection can effectively transfer and disperse stress, preventing loosening or breakage at the connection point, and greatly improving the stability and safety of the overall support structure. Especially under large dynamic loads or during long-term use, it can maintain good structural integrity.
[0007] As a preferred technical means: the railing fixing device includes a cylinder with an open top and a closed bottom. Multiple radially penetrating pin holes are arranged vertically on the cylinder. Correspondingly, the lower part of the guardrail has multiple pin holes. The guardrail is inserted into the cylinder from top to bottom and fixed by locking pins. The right side of the cylinder and the short vertical post are welded together. The multiple locking pins connecting the cylinder and the guardrail ensure stable and reliable fixing of the guardrail and facilitate disassembly. The cylinder is fixed to the short vertical post by welding, ensuring a firm connection between the railing fixing device and the frame, preventing loosening or displacement of the railing fixing device during use, thereby ensuring that the guardrail can always stably perform its protective function.
[0008] As a preferred technical means, the hook is made of steel plate by cutting and forming, and the left side of the hook is fixed to the right side of the vertical rod by welding. The material properties of the steel plate itself and the cutting and forming process can ensure that when the hook is attached to the membrane water-cooled wall, it can bear the weight of the entire platform support and the operators, and will not easily deform or be damaged, thus improving the reliability of the support installation.
[0009] As a preferred technical approach, the welding between the hook and the frame, between the reinforcing connecting rod and the vertical connecting rod, and between the cylinder and the short vertical rod all employ full penetration welds. Using full penetration welds ensures complete fusion of the weldment, guaranteeing weld quality. Compared to ordinary welds, full penetration welds have higher strength and effectively prevent defects such as cracks and incomplete fusion at the weld, improving the safety and stability of the entire support structure. Especially when subjected to significant tensile or impact forces, it ensures that the connection between the hook and the frame will not fail.
[0010] As a preferred technical means, the support member is made by transversely cutting a channel steel. The back of the channel steel is located on the left side, and the flanges on both the front and rear sides of the channel steel are located on the right side. The middle of the back of the channel steel is welded and fixed to the right side of the vertical rod. Structurally, the flanges on both sides of the channel steel can serve as two support points at the front and rear. Furthermore, the structure of the flanges can increase the contact area between the support member and the fins, disperse pressure, reduce the risk of damage to the fins due to excessive local pressure, and also improve the stability of the support. The back welding fixation can effectively transfer the weight and load of the bracket to the membrane wall tube fins.
[0011] As a preferred technical means, the contact surfaces between the flanges on both the front and rear sides of the channel steel and the membrane wall fins are provided with anti-slip serrations. This increases the friction between the flanges and fins, effectively improving the friction between the flanges and fins when the support is subjected to external forces in high-altitude working environments. This ensures the installation stability of the support on the membrane wall tube fins and provides a safer working platform for workers.
[0012] As a preferred technical means, a buffer pad is provided on the contact surface where the anti-slip teeth are located. The buffer pad can play a buffering role. When the support is subjected to impact or vibration, the buffer pad can absorb some of the energy, reduce the impact force on the membrane wall fins, and protect the fin surface from damage.
[0013] As a preferred technical means, reflective warning strips are provided on the surface of the guardrail. The width of the reflective warning strips is not less than 50mm, and the spacing is not greater than 300mm. In low-light environments, the reflective warning strips can reflect light and play a clear warning role.
[0014] Beneficial effects: By hanging multiple simple platform supports on the membrane water-cooled wall, and then attaching scaffolding to the horizontal bars of the simple platform supports as working platforms, and stringing safety ropes on the guardrails, protection is provided for workers at height. The safety is high, effectively preventing accidental falls and ensuring the safety of workers. The frame is made of a single round steel bar, which is high in strength. The overall support structure is simple, easy to manufacture, and quick to construct, which can effectively reduce construction costs and enable the rapid construction of simple platforms.

[0021] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings.
[0022] Example 1
[0023] like Figure 1 , 2 As shown, a simple platform support for high-altitude connection of boiler membrane water-cooled wall tubes includes a hook 1, a frame 2, a support component 3, a guardrail 4, and a guardrail fixing device. The frame 2 is integrally bent from a single piece of round steel. The frame 2 includes a vertical long pole 201, a horizontal pole 202 located on the lower left side of the vertical long pole 201, a short vertical pole 203 located on the upper left side of the horizontal pole 202, and a reinforcing connecting pole 204 located at the upper end of the short vertical pole 203. The reinforcing connecting pole 204 is inclined to the upper right, and its upper end is welded and fixed to the upper end of the vertical long pole 201. The reinforcing connecting pole 204 is used to enhance the structural strength of the frame 2, improve the deformation resistance of the entire frame 2 under lateral force or uneven load, and make the support more stable and reliable.
[0024] like Figure 1 , 4 As shown, hook 1 is located at the upper right end of the vertical rod 201 and is used to attach to the membrane water-cooled wall. Hook 1 is made of steel plate. The material properties of the steel plate and the cutting process ensure that hook 1 can withstand the weight of the entire platform support and the workers when attached to the membrane water-cooled wall, and will not easily deform or be damaged. The left side of hook 1 is welded and fixed to the right side of the vertical rod 201 by a full penetration weld 7.
[0025] like Figure 1 , 3As shown, a support member 3 is provided at the lower right end of the vertical rod 201. The support member 3 has two support points symmetrically positioned front and rear of the frame 2, used to support the membrane wall tube fins. The support member 3 is made of channel steel cut laterally, with the back of the channel steel on the left side and the flanges 301 on both the front and rear sides of the channel steel on the right side. The back of the channel steel is connected and fixed to the right side of the vertical rod 201 by a full penetration weld 7. Structurally, the flanges 301 on both sides of the channel steel can serve as two support points at the front and rear. The structure of the flanges 301 can increase the contact area between the support member 3 and the fins, disperse pressure, reduce the risk of damage to the fins due to excessive local pressure, and also improve the stability of the support. The back weld fixation can effectively transfer the weight and load of the bracket to the membrane wall tube fins.
[0026] like Figure 1 , 5 As shown, the short vertical bar 203 is connected and fixed to the guardrail 4 via a guardrail fixing device. The guardrail fixing device includes a cylinder 5 that is open at the top and closed at the bottom. Two radially penetrating pin holes are arranged vertically on the cylinder 5. The lower part of the guardrail 4 has corresponding pin holes. The guardrail 4 is inserted into the cylinder 5 from top to bottom and fixed by locking pins 6. The right side of the cylinder 5 and the short vertical bar 203 are connected and fixed by a full penetration weld 7. The two locking pins 6 connect the cylinder 5 and the guardrail 4, ensuring stable and reliable fixing of the guardrail 4 and facilitating disassembly. The cylinder 5 is fixed to the short vertical bar 203 by welding, ensuring a firm connection between the guardrail fixing device and the frame 2, preventing loosening or displacement of the guardrail fixing device during use, and thus ensuring that the guardrail 4 can always stably perform its protective function.
[0027] During the installation of the simple platform, first select the appropriate number of simple platform supports according to actual needs, and then hang the simple platform supports on the membrane water-cooled wall at certain intervals using hooks 1. The simple platform supports form a stable support structure together through the two symmetrical support points of the support member 3 and the hook connection points of the hooks 1. Then, a scaffold board is erected on the horizontal bar 202 of the simple platform support to serve as a construction work platform. The guardrail 4 is inserted into the cylinder 5 and connected and fixed by the locking pin 6. Finally, a fixed safety rope is strung on the guardrail 4 to provide protection for workers at height. It is highly safe and can effectively prevent accidental falls, ensuring the safety of workers' lives. The overall support structure is simple, easy to manufacture, and quick and convenient to construct, which can effectively reduce construction costs. The simple platform can be built quickly and easily.
[0028] In this embodiment, the round steel material of the frame 2 is 16mm in diameter; the hook 1 is made of steel plate with a thickness of 12mm. The hook 1 can be stamped and then cut, or it can be cut and then stamped into the shape of hook 1; the support 3 is made of 12# channel steel; the guardrail 4 is made of DN25mm steel pipe; the cylinder 5 is cut from DN32mm steel pipe and the bottom is sealed by welding with a round steel plate.
[0029] Example 2
[0030] Unlike the above embodiment, as Figure 2 , 4 As shown, the upper end of the reinforcing connecting rod 204 is provided with a vertical connecting rod 205, which is attached to the upper left side of the vertical rod 201. The two are welded and fixed together by a full penetration weld 7. This effectively enhances the connection strength between the reinforcing connecting rod 204 and the vertical connecting rod 205. This welded connection can effectively transfer and disperse stress, preventing loosening or breakage at the connection point, and greatly improving the stability and safety of the overall support structure. Especially under large dynamic loads or during long-term use, it can maintain good structural integrity.
[0031] Example 3
[0032] Unlike Embodiment 1 or 2 above, as Figure 3 As shown, the contact surfaces between the flanges 301 on both the front and rear sides of the channel steel and the membrane wall fins are provided with anti-slip serrations. This increases the friction between the flanges 301 and the fins, effectively improving the friction between the flanges 301 and the fins when the support is subjected to external forces in high-altitude working environments. This ensures the installation stability of the support on the membrane wall tube fins and provides a safer working platform for workers.
[0033] The contact surface where the anti-slip serrations are located is equipped with a cushioning pad. The cushioning pad can act as a buffer; when the support is subjected to impact or vibration, the cushioning pad can absorb some of the energy, reduce the impact force on the membrane wall fins, and protect the fin surface from damage.
[0034] Example 4
[0035] Unlike embodiments one, two, or three above, the surface of the guardrail 4 is provided with reflective warning strips. The width of the reflective warning strips is equal to 50mm, and the spacing between the reflective warning strips is equal to 280mm. In low-light environments, the reflective warning strips can reflect light and play a clear warning role.
[0036] The above-described simple platform support for high-altitude connection of boiler membrane water-cooled wall tubes is a specific embodiment of this utility model, which has demonstrated the substantial features and progress of this utility model. Based on actual usage needs, equivalent modifications in shape, structure, etc., can be made to this utility model under its guidance, and all such modifications are within the scope of protection of this solution.
