Problems solved by technology

[0003] Among the main technical parameters of the draft tube, the gap between the blade and the draft tube is small, usually only Δ=15mm, and the coaxiality and roundness of the inner shell wall of the draft tube require high manufacturing accuracy. If prefabricated in blocks It will be difficult to meet the manufacturing accuracy if it is closed again. Corner joint deformation is easy to occur at the interface, and distortion and deformation are also prone to occur during the welding process. It is difficult to control the overall line shape and precision; Roundness is also difficult to guarantee

Embodiment Construction

[0024] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0025] refer to Figure 1 to Figure 5 This embodiment provides a tire frame for ship draft tube manufacturing, including several groups of tire frame components 1, several groups of tire frame components 1 are connected in sequence and arranged in a ring, and the tire frame components 1 include a structure for defining the longitudinal direction of the draft tube 10. The longitudinal template 2 in the direction position and several transverse templates 3 used to define the transverse direction of the draft tube 10, and several transverse templates 3 are connected to one side of the longitudinal template 2 sequentially along the longitudinal direction.

Abstract

The invention relates to the technical field of shipbuilding, in particular to a jig frame for manufacturing flow guide pipes of ships. The jig frame comprises a plurality of jig frame assemblies. Themultiple jig frame assemblies are sequentially connected with one another, are annularly arranged and comprise a plurality of longitudinal mold plates and a plurality of transverse mold plates, the longitudinal mold plates are used for restraining the locations of the flow guide pipes in the longitudinal directions, the transverse mold plates are used for restraining the flow guide pipes in the transverse directions, and the multiple corresponding transverse mold plates are sequentially connected to a side of each longitudinal mold plate along the longitudinal directions. The jig frame has the advantages that the flow guide pipe welding efficiency can be effectively improved by the jig frame, twist deformation of the flow guide pipes in welding procedures can be reduced, and accordingly the planeness of front and rear end surfaces of the flow guide pipes and the roundness of inner shell walls of the front and rear end surfaces of the flow guide pipes can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of ship manufacturing, in particular to a tire frame for manufacturing ship draft tubes. Background technique [0002] The draft tube is a hydrodynamic energy-saving device, which can improve the uniformity of the propeller inflow field. By improving the efficiency of the hull and reducing the rotational energy loss of the propeller stern flow field, a high energy-saving effect can be obtained, and the energy saving can reach 3%~ 8%. [0003] Among the main technical parameters of the draft tube, the gap between the blade and the draft tube is small, usually only Δ=15mm, and the coaxiality and roundness of the inner shell wall of the draft tube require high manufacturing accuracy. If prefabricated in blocks It will be difficult to meet the manufacturing accuracy if it is closed again. Corner joint deformation is likely to occur at the interface, and distortion and deformation are also prone to occur during ...
