An automatic moving system for heat treatment pillars of spherical tanks

Abstract

The invention relates to an automatic moving system for thermal treatment supports of a spherical tank. The system comprises a signal transmitting and receiving device, an assistant support moving device and a system control device, wherein the signal transmitting and receiving device comprises a signal transmitter and a signal receiver, and each of the signal transmitter and the receiver is provided with a magnetic base which is directly attracted on the outside of the support of the spherical tank; the system control device is a micro PC which is respectively connected with and controls the signal transmitting and receiving device and the assistant support moving device; the assistant support moving device is installed on a bottom plate of the support of the spherical tank and comprises a traction mechanism, a fixing bracket and a movement mechanism. The system provided by the invention can be installed rapidly, is convenient to use and simple to operate and can move all supports the same distance at the same time in the thermal treatment process of the spherical tank.

Description

technical field [0001] The invention relates to the technical field of heat treatment machinery and equipment, in particular to an automatic moving system for a heat treatment pillar 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 ...

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
