Problems solved by technology
Due to various factors during the production, transfer and storage of the leg main chord, there is a risk that the deformation will cause the accuracy to exceed the tolerance requirements
The traditional solution to the deformation of the main chord is to cut the original weld and re-weld, but if a large area of the main chord is repaired, it will consume a lot of manpower, material resources and precious construction time, especially the secondary welding It is very easy to have welding quality problems and lead to the scrapping of the main string pipe
In addition, it is also a method to use a large press of thousands of tons for cold press correction, but this method must rely on a large press of thousands of tons, and the scope of promotion and application is very limited

Embodiment Construction
[0024] The present invention designs a set of fixation at several points, loading at several points, and completion of rectification of the main chord pipe of the pile legs through mechanical rectification. The number of fixed points and loading points is determined according to the deformation of the main chord. In the optimal mode, two points are used for fixing and loading.
[0025] The orthopedic equipment of the truss type pile leg main chord pipe of the present invention, such as Figure 1~4 As shown, for the setting of rectification in the crown direction of the main chord, two or more portal frames 3 are arranged at intervals on the rigid orthopedic workbench 2 .
[0026] Such as image 3 As shown, the crown orthopedic fixing seat assembly 4 sits on the rigid orthopedic workbench 2, including fixed structures on both sides of the upper part, and the middle part of the fixed structure is clamped on both sides of the rack on one side of the main chord 1 by wooden teeth ...

The invention discloses shaping equipment of a main cord pipe of a truss framed leg. The shaping equipment comprises a rigid shaping worktable 2, two or more door frames 3 are arranged on the worktable 2 at intervals, a jack 6 with a pressure sensor 5 is suspended on each door frame 3, and for two shaping conditions in the camber direction and the flatness direction of the main cord pipe, replacement ways are set including a camber shaping fixing seat component 4 and a flatness shaping fixing seat component 9 on the worktable 2 and a camber shaping press head 7 and a flatness shaping press head 10 at the lower end of the jack 6. The shaping equipment of the main cord pipe of the truss framed leg can meet the shaping requirements of most main cord pipes of truss framed legs and can effectively complete shaping of the main cord pipes of the truss framed legs. The shaping equipment has the advantages of no influences on mechanical performance of the main cord pipes, convenience in detection, low risk, high safety, high shaping efficiency, recyclability, low cost and the like.
Description
technical field [0001] The invention relates to the construction of truss-type pile legs of a self-elevating platform, in particular to the orthopedic technology of the main chord pipe of the pile legs. Background technique [0002] The leg is the key structure of the jack-up platform, and the main chord of the leg is the key structure of the leg. For example, the Chinese patent "dimension detection flipping tool for the main chord of pile legs" (authorized announcement number CN203605924U) relates to the specific structure of the main chord. At present, the most widely used jack-up platform legs are truss structures, and the construction precision requirements of the main chords are very high. Due to various factors during the production, transfer and storage of the leg main chord, there is a risk that the deformation will cause the precision to exceed the tolerance requirement. The traditional solution to the deformation of the main chord is to cut the original weld and ...
