Description

Technical Field

[0001] The present invention relates to the technical field of self-elevating platform processing, in particular to an assembling method of a cross-shaped lifting foundation sheet of a self-elevating platform. Background Art

[0002] The lifting foundation of the self-elevating platform is a key load-bearing structure. It is located above the platform body and connected by welding. The lifting unit installed inside it is engaged with the pile leg rack through the climbing gear, and bears the entire load of the platform body. This structure usually adopts a three-layer design of front plate, middle plate and rear plate. Each layer is arranged with mounting seats and horizontal and vertical partitions to enhance the load-bearing capacity, but the complex internal space leads to a large number of narrow and closed areas, making assembly and welding construction difficult. In the existing technology, weld leakage problems occur frequently, mainly because the process feasibility is not fully considered in the design stage, such as the process holes are not preset or the welding sequence is not optimized, which directly affects the overall quality and safety of the structure. The traditional middle and side arc plates adopt a split-piece design, which needs to be formed separately and assembled during processing, which is prone to cumulative errors and leads to insufficient assembly accuracy. Summary of the Invention

[0045] S8: A through groove 41 is formed in the middle of the arc-shaped inner plate 4 .

[0046] The layered welding of the front plate assembly and the middle plate assembly and the installation of the anti-torsion block 13 of the present application effectively control welding deformation, ensure the gap accuracy requirements between the lifting foundation and the pile legs, and avoid the cumulative error caused by traditional split welding; and the step-by-step assembly method (such as welding the front plate assembly first and installing the middle arc plate as a whole) reduces the difficulty of operation in a small space, reduces the risk of welding leaks, and improves production efficiency; as can be seen from the above embodiments, the present application divides the complex structure assembly into steps and decomposes it layer by layer. Through reasonable assembly and welding sequence, process hole setting, weld seam welding form setting in closed space, welding timing setting, etc., it can reduce construction difficulty, improve construction efficiency, reduce losses, and ensure construction quality; on the other hand, the arc-shaped inner plate 4 adopts an integrated design, cutting, and processing, and is grooved after the sheet is formed. On the one hand, it reduces the processing difficulty of the arc-shaped inner plate 4 (such as the arc plate is too narrow to be pressed, etc.), and on the other hand, it also improves the accuracy of the arc plate after installation, thereby improving the accuracy of the lifting foundation sheet after assembly.

[0047] In some embodiments of the present invention, a first welding area 15 is formed on the front plate assembly. The first welding area 15 will form a closed area after welding.

The third welding area 24 will form a closed area after welding. The third welding area 24 includes the end faces of the middle plate 2, the front plate 1 and the first transverse partition 11 facing the inner arc plate; the arc-shaped inner plate after slotting and the third welding area 24 are welded by single-sided welding, so that the arc-shaped inner plate 4 is firmly fixed to the rear plate 6 and the front plate 1, and the third welding area 24 is completely sealed.
