Embodiment Construction

[0008] With reference to the accompanying drawings, the tank body of the tower-type vertical tank is divided into three parts: the upper pipe section 11, the middle pipe section 6, and the lower pipe section 4. The lower pipe section is 2.5 meters in height and is composed of an arc surface coaming. First, install the tower-type vertical tank For the lower body part, the lower pipe section is welded on the bottom plate 1, and a supporting hoisting platform is set in the lower body part of the tower vertical tank. Arranged on the bottom plate at equal intervals around the circumference, welded and fixed with the bottom plate, the platform plate is fixed on the lower column, the platform plate is 2 meters away from the bottom plate, and no less than nine upper columns are arranged on the platform plate at equal intervals on the circumference, and the upper column The length of the column is 3-3.5 meters. Multiple upper support beams cross the center of the circle in a circle form...

Abstract

The invention relates to an installing method for a tower type vertical tank. The installing method is characterized in that a tank body of the tower type vertical tank is divided into an upper pipe section, a middle pipe section and a lower pipe section, firstly, the lower pipe section is welded to a bottom plate, a supporting hoisting platform is arranged in the lower body part of the tower type vertical tank, and is composed of lower vertical columns, a platform platen, upper vertical columns and upper supporting beams, and a chain block is installed on the outer side of the top of each upper vertical column; the upper pipe section is manufactured on the ground, the upper pipe section is vertically hoisted through a crane, and the upper pipe section is erected on the lower body part of the tower type vertical tank; the middle pipe section is divided into three to four arc surface surrounding plates; a worker stands on the platform platen to work, the upper pipe section is lifted through the chain blocks, the surrounding plates of the middle pipe section are hoisted one by one through the crane to be connected to the lower pipe section in a welded mode, and the upper pipe section and the middle pipe section are connected in a welded mode. The installing method has the advantages that the supporting hoisting platform is adopted for operation, good stability is achieved, and limitation of time is avoided; the danger caused by aloft work can be effectively solved.

Description

technical field [0001] The invention relates to an installation method for a tower-type vertical tank, which belongs to the field of installation and construction of metallurgical machinery and equipment. Background technique [0002] In metallurgical machinery installation projects, some tall tower-type vertical tanks cannot be installed by cranes, which brings a lot of inconvenience and troubles to the engineering installation. For example: a tower type vertical tank, a large tank with a steel plate thickness of 30mm, a diameter of 5m, and a height of 80m, will bring difficulties to the installation because the tank body is gradually increased during installation. There are the following problems: the installation conditions are restricted: (1) after the tank body is gradually increased, the main arm of the truck crane and the radius of gyration are limited to increase again. If it is hoisted with a large truck crane, it will take a long time to use the car and the cost w...
