The invention provides a multifunctional assembly platform for a large-diameter penstock. According to the multifunctional assembly platform, the assembly, welding and roundness correction efficiency of the penstocks is greatly improved, and the situation that a temporary supporting platform for assisting in assembly and welding of the penstocks needs to be continuously installed and dismantled during assembly and welding of the penstock is avoided. Due to the fact that assembly, welding and roundness correction of the penstocks are repeated and continuous work, the installation stability of assembly and welding of the penstocks is improved due to the existence of the assembly platform, and the construction quality is improved. Multiple operator bearing platforms are arranged on an assembly framework, and operators assemble and weld the penstocks on the operator bearing platforms. A rounding device is assembled on the operator bearing platforms and can effectively conduct rounding work on the penstocks. According to the multifunctional assembly platform for the large-diameter penstock, the assembly framework is simple in structural form, single in needed material, convenient and fast to manufacture and high in operability and practicability, the construction efficiency of assembly, welding and roundness correction of the penstocks is effectively guaranteed, and therefore the installation cost is reduced.
Description
technical field [0001] The invention relates to the technical field of pressure steel pipe fabrication and installation, in particular to a multifunctional assembly platform for large-diameter pressure steel pipes. Background technique [0002] The pressure steel pipe assembly, welding and rounding platform, commonly known as the assembly platform, is assembled and welded by section steel. It is applied to the pressure steel pipe assembly, welding and rounding, which not only greatly improves the construction efficiency, but also saves labor and reduces the pressure steel pipe manufacturing economy. cost. [0003] In the production process of penstocks in hydropower stations, because penstocks are large-diameter and heavy-duty pipe fittings, not only assembly and welding platforms are required in assembly, welding, and calibration, but also calibrating dome frames are required for calibrating construction. When assembling and welding, in the traditional operation, wooden bo...
