Description

Technical Field

[0001] This utility model relates to a welding operation tool, and in particular to a tank welding operation platform. Background Technology

[0002] In modern industry, various tanks are widely used in petroleum, chemical, energy, food, and other fields. The welding efficiency and quality of these tanks are crucial to production efficiency and product performance. To meet the needs of tank welding operations, temporary, simple operating platforms are often erected. These platforms are divided into two types: steel pipe scaffolding platforms and welded steel frame platforms. Steel pipe scaffolding platforms require a large amount of space, take a long time to assemble and disassemble, consume a lot of manpower, and have high construction costs. Welded steel frame platforms have high requirements for welding quality, are designed according to the dimensions of the tank's concrete foundation, and the equipment used is basically non-reusable. Furthermore, both of these temporary platforms suffer from poor stability, significant safety hazards, lack of protective measures, lack of versatility, waste of equipment resources, impact on welding progress, and increased project costs. Therefore, it is particularly important to provide a welding platform that is applicable to various types of tanks with different diameters and heights. Utility Model Content

[0003] The purpose of this utility model is to solve the drawbacks of temporarily setting up traditional platforms and to provide a tank welding operation platform that occupies a small area, has a solid structure, is safe to use, can be quickly assembled and disassembled, can speed up welding, help improve welding quality, reduce construction costs, and can be adapted to the welding requirements of tanks of different specifications.

[0004] The objective of this utility model can be achieved. This utility model's tank welding operation platform includes a tank and a concrete foundation for the tank. The platform is characterized by the following: several I-beams are anchored around the perimeter of the concrete foundation using chemical anchors. These I-beams are horizontally fixed on the circumference of the concrete foundation, forming a ring-shaped planar load-bearing structure. Each I-beam has a vertical post at both ends connected to a base. The tops of the two vertical posts are connected to a horizontal bar coaxial with the I-beam. Adjacent horizontal bars are connected to a set of longitudinal horizontal bars. Several adjacent horizontal bars are connected to a set of longitudinal horizontal bars, forming a ring-shaped platform structure. A steel mesh is laid on the ring-shaped platform structure to form a ring-shaped operation platform. The ring-shaped operation platform surrounds the tank, and welds are performed on the bottom layer of the tank on the platform.

[0005] This utility model relates to a tank welding operation platform, wherein the I-beam is a 16# I-beam, which is anchored at two-thirds of the height of the tank's concrete foundation. A 6*200*250mm steel beam fixing plate is welded to the end of the I-beam near the tank's concrete foundation. The I-beam is centered along the longitudinal direction of the steel beam fixing plate. Each end of the steel beam fixing plate has a φ24mm anchor bolt hole centered at 30mm from the edge. A reinforcing rib is welded above the joint between the I-beam and the steel beam fixing plate, perpendicular to the center line of the steel beam fixing plate.

[0006] This utility model relates to a tank welding operation platform, wherein the upright base on the I-beam is a clamp that clips onto the flange of the I-beam. The clamp is fixed to the I-beam by a flange clamp plate on one side of the web of the I-beam and bolts. An upright is welded to the upright base, and a guardrail is connected to the outer upright.

[0007] This utility model relates to a tank welding operation platform, wherein the uprights and horizontal bars are connected by right-angle couplers, and the horizontal bars and longitudinal bars are connected by swivel couplers. The guardrails are connected to the uprights by right-angle couplers.

[0008] The present invention relates to a tank welding operation platform, wherein the longitudinal horizontal bars are at least four in a group, and the number of longitudinal horizontal bars in each group connected between each adjacent transverse horizontal bar is the same.

[0009] This utility model relates to a tank welding operation platform, wherein the steel mesh is fully laid on the longitudinal horizontal bar, and the four corners and the middle of the steel mesh are fixed by galvanized iron wire wrapped around the longitudinal horizontal bar. The corners are overlapped, with an overlap length of not less than 200mm, and are tied together by galvanized iron wire.

[0010] This utility model's tank welding operation platform differs from existing technologies in that it includes a concrete foundation for the tank. Several I-beams are horizontally anchored around the tank foundation using anchor bolts, forming a ring-shaped planar load-bearing structure. Each I-beam has a vertical pole at each end, and the tops of the two vertical poles are connected to a horizontal bar coaxial with the I-beam. Adjacent horizontal bars are connected to a group of at least four longitudinal horizontal bars, and each pair of adjacent horizontal bars is connected to an equal number of longitudinal horizontal bars, forming a ring-shaped platform structure. The ring-shaped platform structure is fully covered with steel mesh to form a ring-shaped operating platform. Workers stand on the ring-shaped operating platform to perform welding operations on the tank seams. This utility model's tank welding operation platform is rationally designed, structurally robust, safe, and reliable. It combines the advantages of the high stability of steel pipe scaffolding platforms and the ease of installation of steel frame platforms. It allows for rapid assembly and disassembly, helps improve welding quality, and ensures the performance of various types of welded tanks. This utility model's tank welding operation platform can be erected once and used for a long time without the need for repeated erection, saving material resources. It is suitable for welding tanks of different specifications, and can improve welding speed and reduce engineering costs.
