Abstract

The present invention relates to a set of movable platforms for inspecting internal pipe equipment. It comprises a rectangular work platform installed to rest on a set of steel pipes placed on the inner floor of the pipe to support the work platform during the inspection of equipment constructed inside the pipe; handrails assembled and installed on both sides of the rectangular work platform to guide the movement of workers and prevent safety accidents during the internal inspection of the pipe; and an arc-shaped pipe flange fixing plate formed and attached to one end of the rectangular work platform so as to be fastened with a fixing bolt to the pipe flange at the entrance to concentrate the arrangement of the set of steel pipes and prevent movement of the rectangular work platform. By installing and using a movable platform that fits the diameter of the pipe during the inspection of internal pipe equipment, it is possible to induce smooth entry of workers into the pipe and secure sufficient workspace. Furthermore, by providing disassemblable handrails on both sides of the work platform, it is possible to prevent industrial accidents such as falls during work and slip accidents during the installation of steel pipe scaffolding, thereby improving work efficiency.

Description

Transfer platform set for inspecting inside equipment of plumbing The present invention relates to a set of movable platforms for inspecting internal pipe equipment. Specifically, the invention relates to a set of movable platforms for inspecting internal pipe equipment that improves work efficiency by preventing industrial accidents such as falls during work and slipping accidents when installing steel pipe scaffolding, by installing and using a movable platform that fits the diameter of the pipe during the inspection of internal pipe equipment, thereby facilitating smooth entry of a worker into the pipe and securing sufficient workspace, while also being equipped with detachable and assembleable handrails on both sides of the platform. Generally, "spanning platform for inspecting internal piping equipment" is a widely disclosed item, so a detailed description is omitted; however, reference may be made to Published Utility Model No. 20-2023-0001209 "Multipurpose work safety platform" and Registered Patent No. 10-2100383 "System scaffolding for inspecting internal piping," etc. Meanwhile, the aforementioned "multi-purpose work safety platform" is designed to be installed using beams or pipes that constitute the piping or supports of a workspace where the gas turbine's intake air filter is installed; however, since it is used as an inspection platform utilizing steel pipe scaffolding, there are problems such as a narrow width due to the diameter limitation of the entrance and the risk of industrial accidents caused by falling and slipping during work at height. Furthermore, although the aforementioned “system scaffolding for internal pipe inspection” is designed to improve work efficiency and ensure safe operation by standardizing installation and dismantling to reduce manpower and time and lower costs, it is limited to inclined supports installed on the inner walls of inclined pipes. Consequently, when steel pipe scaffolding is used as an inspection platform, there are problems such as a narrow width due to the limited diameter of the entry point, and a risk of industrial accidents caused by falls and slipping during work at heights. Meanwhile, since steel pipe scaffolding is generally used as an inspection platform when workers enter the pipe to perform work during equipment inspections installed inside the pipe, there is a problem in that the entry point is narrow due to diameter limitations, and there is a risk of industrial accidents caused by falls and slips during work at heights. FIGS. 1a), 1b), and 1c) are drawings illustrating a set of movable platforms for inspecting internal piping equipment according to the present invention. FIG. 2 is a schematic drawing showing the installation inside the piping of the movable platform shown in FIG. 1. FIGS. 3a)b) is a schematic drawing showing the front and side of the movable platform shown in FIG. 2. FIG. 4 is a plan view schematically illustrating a work platform on a movable platform shown in FIG. 2. To fully understand the present invention, preferred embodiments of the invention will be described with reference to the accompanying drawings.
