Auxiliary spherical tank brace moving device

Abstract

The invention provides an auxiliary spherical tank brace moving device which comprises a traction mechanism, a fixing support and a moving mechanism, wherein the fixing support comprises a rectangular frame; any two sides of the rectangular frame can slide on the other two sides of the rectangular frame so as to realize the regulation of the size of the frame; a fastening mechanism and a platform which is used for mounting the moving mechanism are mounted on the rectangular frame; the traction mechanism is a L-shaped traction arm with an downward opening; one end of the traction mechanism is connected with a spherical tank brace baseplate; the other end of the traction mechanism is connected with the moving mechanism; the moving mechanism comprises a base mounted on the platform; a hydraulic jack is mounted on the base; a piston of the hydraulic jack extends outside to prop the traction arm; the directions of axial lines of the hydraulic jack and the traction arm are the same as the moving directions of spherical tank braces. The device provided by the invention is rapid to assemble, convenient to use and simple to operate; all the braces during the heat treatment of a spherical tank can be simultaneously and uniformly moved; the moving distances of the braces are the same.

Description

technical field [0001] The invention relates to the technical field of heat treatment mechanical equipment, in particular to an auxiliary moving device for a support of a spherical tank. Background technique [0002] The spherical tank is a pressure vessel mainly used to store liquid or gaseous materials in the petrochemical industry, and plays a vital role. Spherical tanks are generally constructed in the form of pressing in the factory, assembly and welding on site. When the spherical tank is assembled on site, there is a heat treatment process, which can refine the grains of the welded joints and strengthen the mechanical properties. This process uses flames to directly heat the inside of the spherical tank, and the spherical tank will expand and become larger as the temperature continues to rise. According to the relevant regulations of GB50094-2010: during the heat treatment of the spherical tank, an auxiliary mobile device should be installed at the bottom of the pil...

AI Technical Summary

Problems solved by technology

[0003] At present, during the heat treatment of spherical tanks, every time the temperature of the spherical shell changes by 100°C, the pillars must be adjusted once. However, most domestic manufacturers of spherical tanks use the method of beating the bottom plate of the pillars to make them move. When using this method, when moving the pillars, every time The root pillar needs to be equipped with 2 workers to operate, knocking the pillar will affect the strength of the weld seam at the bottom plate of the pillar, and it is not guaranteed that each pillar moves the same distance each time
