Description
Technical Field
The invention relates to a novel assembly tool which can ensure the practicability of spherical tank assembly, can realize complete mechanical assembly and disassembly, does not need gas cutting and electric welding, saves energy and does not pollute the environment.
Background
A spherical pressure container (a spherical tank for short) is one type of storage tank, the container is classified into three types, and most of the containers are used for containing liquid hydrocarbon and other media. The spherical tank can be divided into a tangerine petal type and a mixed type in structure, and can be divided into a plurality of types, such as 3 belts, 4 belts, 5 belts, 7 belts and the like. Compared with other storage tanks, the spherical tank has the advantages that the design thickness of the spherical tank is the smallest under the same design pressure due to the fact that the circumferential stress and the radial stress of the spherical shell plate are consistent, the surface area of the spherical tank is the smallest under the condition that the design pressure of the container is the same, and the used materials are the least. Due to the special structure of the spherical tank, the difficulty of assembly and welding is higher than that of other types of containers. During the equipment, carry out the equipment in equatorial zone earlier, polar zone under the installation is accomplished to equatorial zone installation, extremely take the installation to accomplish down the back, begin to fill the shelf in the spherical tank, in order to guarantee the security, the shelf should adopt the pole and the springboard of steel material, and in order to guarantee the fastness of shelf, need weld the pole of steel material to the inner wall of spherical tank body on, then according to the process installation polar zone the same with extremely take down, finally accomplish the equipment of whole spherical tank. After the assembly is completed, the interior of the spherical tank needs to be welded.
After the welding is accomplished, move the shelf of the steel material in the spherical tank outside the spherical tank, because the volume of shelf is great, the manhole footpath of spherical tank is less, so need use the gas cutting to cut up the shelf after clearance out the spherical tank, the utilization ratio of shelf is very low, causes very big waste easily, and cutting and welding relapse can cause unnecessary environmental pollution moreover.
Although there is a technology of adopting a tripod structure to replace a scaffold and other structures in the prior art, the tripod structure is formed by connecting a horizontal rod, a vertical rod and an inclined support rod, and the inclined support rod is used for adjusting the levelness of the horizontal rod. At the in-process of the levelness of adjusting the horizon bar, need loosen the checkpost between horizon bar and the bearing diagonal pole, adjust horizon bar and bearing diagonal pole simultaneously, because steel's tripod structure has great weight, be difficult to operate horizon bar and bearing diagonal pole simultaneously.
