Embodiment 1

[0064] see figure 2 – Figure 11 , used for the welding deformation control process of the bolt-type lifting platform pile legs, the pile legs include an outer cylinder 1, a pasting plate 2, a ring rib 3, a long longitudinal rib 4, a pin hole 5 and a pin box 6; The interior of the cylinder 1 is provided with long longitudinal ribs 4, ring ribs 3, and latch boxes 6. The number of the long longitudinal ribs 4 is four, and the long longitudinal ribs 4 are arranged symmetrically with respect to the central axis of the cylinder 1. , every two long longitudinal ribs 4 form a group, a plurality of latch boxes 6 are clamped between the inner walls of the two long longitudinal ribs 4 in each group, and the outer walls of the two long longitudinal ribs 4 in each group are respectively connected There are upper ring ribs 31 and lower ring ribs 32 to form a whole ring rib 3. The ring ribs 3 are arranged at intervals along the distribution sequence of the latch box 6. The latch box 6 inc...

Abstract

The invention provides a welding deformation control process used for manufacturing a plug type hoisting platform pile leg. The welding deformation control process sequentially comprises the following four steps: assembling a part; welding long vertical ribs, annular ribs and separation plates; forming plug holes; assembling and welding a flitch plate. The whole process is carried out according to the sequence of assembling and then welding; in an assembling process, an annular support and supporting profile steel are additionally arranged so that the structure rigidity of the whole body of an outer barrel is increased, and furthermore, the deformation caused by welding is overcome; in a welding process, the annular ribs and the long vertical ribs are sequentially welded; the welding deformation is controlled by adopting a welding sequence of carrying out symmetrical welding from the middle part to the two ends, and crossed separated symmetrical welding and the like. According to the design, deformation by the welding is not easily generated, and the whole size precision is high.

Description

technical field [0001] The invention relates to a hydraulic pin-type lifting platform, in particular to a welding deformation control process for making legs of the pin-type lifting platform, which is particularly suitable for controlling welding without deformation and ensuring high precision of the overall size. Background technique [0002] The hydraulic plug-in lifting platform is a kind of self-elevating offshore platform, which is mainly used in offshore areas. The main applicable ship types include wind power installation ships, offshore drilling ships and elevating barges. The main structure of the hydraulic pin-type lifting platform is divided into solid pile frame, pile legs, pile boots, platform and other parts, among which the pile legs are important load-bearing and force-transmitting components of the platform, and the maximum load-bearing capacity of a single pile leg is 450 tons . The outer cylinder of the pile leg passes through the hole in the pile frame a...
