Installation tooling and installation method for large-span and large-diameter pipes on a roof

Abstract

The invention relates to a roof large-span large-diameter pipe installing tool and installing method. The installing tool comprises a truss, guide carrier rollers, a portal frame and an electric block. The portal frame is a rectangular frame structure formed from I-beams; the portal frame is arranged on a roof; the electric block is arranged at the top end of the portal frame; the truss is arranged on the roof after penetrating the portal frame. Each guide carrier roller comprises a pedestal and two roller wheels used for carrying and conveying pipes; the pedestal is fixedly arranged on the truss and the two roller wheels are arranged at the two ends of the pedestal; the distance between the two roller wheels is less than the diameter of the pipes. The truss penetrates pipe supports on the roof; the two roller wheels of each guide carrier roller are higher than the pipe supports on the roof; the roof is provided with a lifting opening at the portal frame. The problem in maintenance and installation of pipes on roofs that a hoist cannot be used at a large-span factory and the periphery thereof for hoisting is solved; the installing tool and the installing method have no influence on production in the factory.

Description

technical field [0001] The invention relates to a pipeline installation tool and installation method, in particular to a roof large-span and large-diameter pipeline installation tool and installation method. Background technique [0002] At present, large-diameter pipelines are basically installed on the ground or underground, but some units need to install large-diameter gas pipelines on the roof of the factory building. At this time, it is often necessary to install pipelines across obstacles during pipeline construction, or even use Large-tonnage cranes cannot reach the pipe installation site. The existing method is to use trusses for installation. Although it can solve some problems, there are still some problems that cannot be solved for the installation of large-diameter pipes in pairs on the roof. For example, the truss itself cannot be used. Direct installation by crane, how to carry out the on-site assembly and installation of the truss itself, the limitation of the...

[0002] At present, large-diameter pipelines are basically installed on the ground or underground, but some units need to install large-diameter gas pipelines on the roof of the factory building. At this time, it is often necessary to install pipelines across obstacles during pipeline construction, or even use Large-tonnage cranes cannot reach the pipe installation site. The existing method is to use trusses for installation. Although it can solve some problems, there are still some problems that cannot be solved for the installation of large-diameter pipes in pairs on the roof. For example, the truss itself cannot be used. Direct installation by crane, how to carry out the on-site assembly and installation of the truss itself, the limitation of the construction load of the roof system, the height of the roof, and the initial installation cost of the truss and other tooling is relatively high
