Embodiment Construction

[0020] In order to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, see Figure 1 to Figure 4 :

[0021] The anti-deformation cable for assembling and welding large-scale horizontal storage tanks implemented according to the present invention is used for assembling and welding the cylinder joint 6 of the large-scale horizontal storage tank body. The structure of this embodiment is similar to the spokes of bicycle wheels. The arc-shaped shell plate is connected to the cable, and the cable generates a pre-tightening force to resist welding deformation. In order to conveniently adjust the tension of the cable according to the site conditions, the cable is composed of lug plate 1, tightening device 2, steel wire rope 3, connecting plate 6, and bearing 4. The lug plate 1 is evenly distributed and connected to the arc-shaped shell plate of t...

Abstract

The present invention relates to the field of an assembling and welding device of large-scale horizontal tanks, in particular to a method for preventing deformation of guyed assembling and welding a large-scale horizontal storage tank shell section. The method is characterized by comprising the following steps of: connecting adjustable stay cables in the internal wall of the shell section after assembling an arc-shaped shell board of the shell section, tightening the stay cables, applying a deformation reacting force, then assembling and welding. The method adopts the steel wire ropes and a screwing device to connect the internal parts of the horizontal storage tank, and prevents the deformation through tightening the steel wire ropes. The method can quickly adjust the screwing device to adjust the tightening force of the steel wire ropes according to the states in the field, thereby further adjusting the deformation quantity; simultaneously, the method can directly adjust parts of the large-scale horizontal storage tank whose ovality exceeds the standard for meeting the requirements of the construction technology. The device can be conveniently detached and reused.

Description

technical field [0001] The invention relates to the field of welding equipment for large horizontal tanks, in particular to an anti-deformation cable which can not only prevent deformation but also be used as a tool for adjusting the ellipticity of a tank body. Background technique [0002] The main equipment of a full-pressure liquefied petroleum gas (LPG) carrier is a large horizontal storage tank, which is used to store and transport liquefied petroleum gas. The characteristics of the storage tank of the LPG transport ship: large volume, high quality, long length, the storage tank is composed of a straight cylinder and a head, and it is a ship-borne pressure vessel. Due to the difficulty of construction, there are not many units in China with such construction capabilities. Generally, horizontal tanks are constructed by on-site bulk method. [0003] The body of a large horizontal storage tank is usually composed of multiple segments, namely barrel sections, and each seg...
