A device and method for verticality measurement of cylindrical steel storage tank inversion process

Abstract

The invention discloses a device and a method for measuring the cylindrical steel storage tank inversion process verticality. The device comprises a tank body top end fixture and a tank body bottom end fixture, wherein the two parts are connected into a whole body through a wire; a lead drop is arranged at one end of the wire; the tank body top end fixture forms a fixed thread plate comprising a single steel plate; a U-shaped notch is formed in one side of the upper end of the fixed thread plate; a thread jamming bolt is arranged on the fixed thread plate; the tank body bottom end fixture comprises a steel plate with a positioning control hole; a coiling device is arranged on the steel plate with the positioning control hole; a support is arranged under the steel plate. The method can monitor the verticality deviation of the cylindrical steel storage tank during the whole reversion construction through only one device, reduces accumulation deviation through the measurement adjustment of the verticality of each two plates with walls, and finally achieves proper control to the verticality. Measurement investments are not required to be erected repeatedly, and the method is not affected by site.

Description

technical field [0001] The invention relates to a device and method for measuring the verticality of various cylindrical steel storage tanks when they are inverted, and is especially suitable for the verticality of large-scale steel storage tanks when the thickness of the tank body increases sequentially from top to bottom. Measuring devices and methods. Background technique [0002] The main structure of the cylindrical steel storage tank is a cylindrical geometry mainly composed of a bottom plate, a wall plate, a roof plate or a top cover. All kinds of steel storage tanks are key links in the production process, or store semi-solid solutions such as flammable, explosive, highly corrosive, and highly permeable. Due to the particularity of its production process and storage, the installation accuracy of steel storage tanks is very high, so how to ensure the verticality of steel storage tanks has become the focus of installation accuracy control. At present, the traditional...
