Abstract

A device for roundness adjustment and supporting of a penstock comprises an inner hub, wherein a plurality of supporting rod assembles are arranged on the outer circumference of the inner hub; each supporting rod assembly comprises at least three supporting rods including a supporting rod connected with the inner hub, an end supporting rod arranged at an end and in contact with the penstock, and an adjusting supporting rod connecting the supporting rod with the end supporting rod; studs are arranged at two ends of the adjusting supporting rod; and internal threads are formed in the supporting rod and the end supporting rod in corresponding positions. The device provided by the invention has the advantages that the roundness of the penstock can be adjusted conveniently; error caused by deformation of a component can be compensated; repeated use is convenient; the structure is simple; the mounting and the adjustment are convenient; the stress is reliable; the mounting and the disassembly are convenient; and the device also can be used for internal supporting during second stage concrete pouring.

Description

technical field [0001] The invention relates to the construction field of penstock steel pipes for hydropower and water conservancy projects, and is mainly used in the production and installation of penstock steel pipes in hydropower and water conservancy projects for roundness adjustment, which facilitates the internode assembly of penstock steel pipes, avoids internode misalignment, and ensures the pressure steel pipes Installation and welding quality. Background technique [0002] Penstock is an integral part of water delivery structures in water conservancy and hydropower projects. It generally bears high water pressure. The quality of fabrication and installation is directly related to the safety of power station operation. Except for small steel pipes, penstocks are generally made into several pipe joints in the manufacturing field. Each pipe section is rolled into several tiles first, and the tiles are assembled into a pipe section on a special platform in the manufa...
