Embodiment Construction
[0042] Specific embodiments of the present invention will be described below.
[0043] like figure 1 As shown, an assembly tooling for the pressure-resistant structure of an inner ribbed cylindrical shell includes a working platform 1, a flatbed truck 2 for loading the cylindrical shell, a frame 3, a suspension shaft 4, a positioning mechanism 37 for clamping and positioning the cylindrical shell, and a For the guiding mechanism of the transfer cylindrical shell and the rib tooling for assembling the annular ribs, the flatbed car 2 is movably arranged on the surface of the working platform 1, and a hole for matching the connecting piece 22 is opened on the flatbed car 2. The hole is a rectangular hole. The suspension shaft 4 is installed through the frame 3, and a plurality of rib tooling is installed from top to bottom on the outer periphery of the suspension shaft 4 facing the working platform 1 and protruding from the frame 3. The positioning mechanism 37 and the guiding me...

The invention relates to an assembly tool of an inner ring rib cylindrical shell pressure resisting structure and an assembly method thereof. The tool comprises a working platform, a flat car for loading cylindrical shells, a frame, a lifting shaft, a positioning mechanism for clamping and positioning the cylindrical shells, a guide mechanism for transferring the cylindrical shells, and rib toolsfor assembling annular ribs; the flat car is movably arranged on the surface of the working platform; the lifting shaft is inserted in the frame; multiple rib tools are mounted at the outer peripheryof the end, towards the working platform and extending out of the frame, of the lifting shaft from top to bottom; the positioning mechanism and the guide mechanism are mounted at the bottom of the working platform through hole structures formed in the working platform; and the guide mechanism is connected with the flat car through a releasing device and a connecting piece. The tool is simple in structure and convenient to use; and after the assembly is finished, no gaps or smaller gaps are formed between the cooled cylindrical shells and the ribs, so that the welding deformation and participation stress problems caused by large assembly gaps are solved.
Description
technical field [0001] The invention relates to the field of pressure-resistant structures of inner-rib cylindrical shells, in particular to an assembly tool for the pressure-resistant structure of inner-rib cylindrical shells and an assembly method thereof. Background technique [0002] As an ideal pressure-resistant structure, the ring-ribbed cylindrical shell structure is widely used in underwater structures such as submarines and submersibles. The ribs of the ring-ribbed cylindrical shell are divided into two types: outer ribs and inner ribs. Under the external pressure of seawater, the weld between the outer ribs and the cylindrical shell is subject to tension, and there is a risk of tearing the weld, while the inner ribs are compressed, so there is no risk of tearing. There is a problem of weld tearing, so the inner rib is more beneficial to the safety of the pressure-resistant structure, especially in the deep-sea high-pressure environment. [0003] The traditional p...
