Large-inclination hydroelectric steel pressure pipe assembling and welding trolley

Abstract

The embodiment of the invention provides a large-inclination hydroelectric steel pressure pipe assembling and welding trolley. The large-inclination hydroelectric steel pressure pipe assembling and welding trolley comprises a front octagonal enclosure frame unit and a back octagonal enclosure frame unit, and the diagonal positions of the two enclosure frame units are connected through outer standcolumns to form an octagonal shape. The front end enclosure frame unit comprises a first enclosure frame body and a second enclosure frame body which are arranged in a spaced mode. Corresponding transverse braces and vertical braces are arranged on the two enclosure frames, and thus three operation platforms are structured. The assembling and welding trolley is reasonable in structure design and suitable for assembling of large-inclination hydroelectric steel pressure pipes; the multiple platforms of the trolley can carry out multiple works synchronously, a lot of field assisting work is reduced, the production efficiency is greatly improved, and a more favorable condition is created for field assembling and application of large-inclination and large-diameter steel pressure pipes.

Description

Technical field [0001] The invention relates to the technical field of pipeline construction, in particular to a large-incline hydraulic pressure steel pipe assembly and welding trolley, which realizes on-site installation and welding of large-incline penstocks. Background technique [0002] In water conservancy and hydropower steel pipe manufacturing and installation projects, the steel pipes are usually assembled and welded into stacks within 8m, and transported to the site with special trailers or rail trolleys for installation. When the penstocks have a large slope and diameter, the on-site pressure seam of the steel pipes , Welding, non-destructive testing, anti-corrosion and other operations will be very difficult, especially for the installation of large-diameter steel pipes in the tunnel. At present, there is no very effective equipment for construction at home and abroad. In order to reduce the transportation cost and reduce the As an auxiliary engineering quantity, par...

Problems solved by technology

[0002] In water conservancy and hydropower steel pipe manufacturing and installation projects, steel pipes are usually welded into stacked joints within 8m, and transported to the site for installation on a special trailer or rail trolley. , welding, non-destructive testing, anti-corrosion and other operations will be very difficult, especially for the installation of large-diameter steel pipes in tunnels. At present, there is no very effective equipment for construction at home and abroad. As for the auxiliary engineering volume, some steel pipe projects adopt the method of assembling and welding the rolled tiles on the platform at the installation site to form steel pipe joints, and then use the rail trolley to transport the steel pipe joints to the installation site, and finally complete the welding and anticorrosion of the steel pipes , but due to the scattered sites and the simple functions of existing equipment, the degree of mechanization of construction is low, the manual operation is difficult, and the production efficiency is low
