Description

Technical Field

[0001] The utility model relates to a reinforcement device, in particular to a cylinder segment reinforcement device. Background Art

[0002] During industrial equipment installation, it's often necessary to fabricate non-standard containers on-site. This is especially true for chemical, metallurgical, and petroleum processing plants, where upright cylindrical containers are often manufactured. Due to their long dimensions and heavy weight, hoisting them as a whole is difficult, necessitating assembly of vertical cylinder segments (or sections). During the cylinder segment assembly process, a crane is required. During the hoisting process, the cylinder segments are prone to deformation, making assembly difficult, resulting in long crane shifts and high costs. To control the roundness of the cylinder segments and facilitate assembly, reinforcement rings are typically installed on the inner wall of the cylinder segment. Symmetrical support methods such as "cross" bracing or multi-point bracing are used to adjust the roundness of the cylinder segment. After hoisting into place, assembly can then proceed.

[0003] In order to obtain local materials, reuse them, quickly process and adjust the roundness of the cylinder segments, and improve work efficiency, the inventors designed a cylinder segment reinforcement device that can effectively solve the problem of cylinder segment deformation during the lifting process.

[0010] As a fourth preferred solution of the present invention, the arc support plate 2 is provided with connecting holes 21 at equal intervals, and the second end of the support section is provided with an opening with the same spacing as the connecting holes 21.
