Embodiment 1

[0017] This embodiment is suitable for a vertical storage tank with a diameter of 8.5m.

[0018] As shown in the figure, the ring-shaped lifting operation platform for vertical storage tanks in this embodiment includes a horizontal ring-shaped operation platform 1, which is suspended on the vertical storage tank, and is respectively arranged on the top and base of the vertical storage tank. Corresponding fixed pulleys 2 are used to lift the fixed rope 3 and pass through the fixed pulleys 2 to connect with the horizontal circular operating platform 1. The inner side of the horizontal circular operating platform 1 is provided with a guide wheel 4 sliding along the outer wall of the vertical storage tank for horizontal circular operation. The platform 1 is surrounded by an annular flat plate 5, six sets of guide wheels 4 are arranged on the inside of the horizontal annular operating platform, six sets of fixed pulleys 2 are arranged on the vertical storage tank, and a horizontal p...

Embodiment 2

[0025] This embodiment is applicable to a vertical storage tank with a diameter of 10m.

[0026] The difference between this embodiment and Embodiment 1 is that the unfolded length of each ring-shaped plate 5 is 4.48m, eight sets of guide wheels 4 are arranged inside the horizontal ring-shaped operating platform, and eight sets of fixed pulleys 2 are arranged on the vertical storage tank.

Embodiment 3

[0028] This embodiment is suitable for a vertical storage tank with a diameter of 15m.

[0029] The difference between this embodiment and Embodiment 1 is that the unfolded length of each ring-shaped plate 5 is 5.15m, ten sets of guide wheels 4 are arranged inside the horizontal ring-shaped operating platform, and ten sets of fixed pulleys 2 are arranged on the vertical storage tank.

Abstract

The invention relates to a ring-shaped lifting operating platform for a vertical storage tank, which comprises a horizontal ring-shaped operating platform hung on the vertical storage tank, and is characterized in that: the top part and the base part of the vertical storage tank are respectively provided with corresponding fixed pulleys; a rope for lifting and fixing passes through the fixed pulleys and is connected with the horizontal ring-shaped operating platform; and a guide wheel which slides along the outer wall of the vertical storage tank is arranged on the inner side of the horizontal ring-shaped operating platform. The ring-shaped lifting operating platform overcomes the difficulties of a construction scheme that a scaffold is arranged outside the vertical storage tank, is less influenced by the environment condition around the storage tank, is suitable for construction of all processes outside the vertical storage tanks with different diameters and different heights, can complete the processes of welding, rust removal and corrosion prevention, heat preservation and the like by repeated lifting, reduces labor intensity, improves construction environment conditions and guarantees aloft work safety.

Description

technical field [0001] The invention relates to a lifting operation platform, in particular to a ring-shaped lifting operation platform for external construction of a vertical storage tank. Background technique [0002] With the continuous development of society, large-scale vertical storage tanks in petroleum, chemical, military, aviation and other industries are more and more widely used. The construction of large-scale vertical storage tanks in my country generally adopts the method of erecting scaffolding inside and outside. The cost of scaffolding is high and the safety is poor. The surrounding site needs to be spacious enough, which is greatly affected by environmental conditions and is not easy to maintain and use. Moreover, for taller storage tanks, it is difficult to set up scaffolding support and tie points, frequent turnover, and a large amount of labor; the radial support and tie points of scaffolding will also become obstacles to the external construction of the...
