Description
Technical field
The utility model relates to a kind of stern tube shaft lengthening bar bar cover, is mainly used in shipbuilding field.
Background technology
In Ship production process, first stern pipe is installed in the stern hole of sternpost, then in stern pipe, stern tube shaft is installed.Because the stern tube shaft volume of large ship is large, quality weight, the quality of stern tube shaft will reach 82 tons, inconvenience is brought in the installation process of stern tube shaft, the more difficult application force applying that on stern tube shaft stern tube shaft is moved in rear and front end of such as stern tube shaft, and the crank of stern tube shaft causes stern tube shaft to be difficult to move in stern pipe, because this reducing installation effectiveness.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of stern tube shaft lengthening bar bar cover for assembling the stern tube shaft lengthening bar that can improve stern tube shaft installation effectiveness.
The purpose of this utility model is achieved in that
A kind of stern tube shaft lengthening bar bar cover, the stern tube shaft linkage section that it is arranged before and after comprising and body of rod linkage section, stern tube shaft linkage section and body of rod linkage section are front latter linked two sections of pipe structures, the inwall of stern tube shaft linkage section is provided with negative thread, the leading portion of the lengthening bar body of rod embeds in body of rod linkage section, hang before the outer rim of the front and back section of stern tube shaft linkage section is respectively arranged with groove and after hang groove, the outer rim of stern tube shaft linkage section is also provided with the multiple handle holes be circular layout.
Preferred as one, the twice hoop arranged before and after the back segment of stern tube shaft linkage section is provided with, after hang the outer rim that groove is arranged at one hoop in front.
Preferred as one, the junction of stern tube shaft linkage section and body of rod linkage section is provided with polylith brace panel, the leading portion that polylith brace panel is evenly arranged in body of rod linkage section is peripheral, the front end of brace panel connects the rear end of stern tube shaft linkage section, is provided with gap between the junction of stern tube shaft linkage section and body of rod linkage section and brace panel.
Compared with prior art, the beneficial effects of the utility model are:
The utility model stern tube shaft lengthening bar bar cover is for assembling the stern tube shaft lengthening bar that can improve stern tube shaft installation effectiveness, be applicable to the installation of the ultralong overweight stern tube shaft of large ship, stern tube shaft easily applies application force, and the steadily of centre of gravity of stern tube shaft can not cause stern tube shaft dyskinesia in stern pipe, therefore improves stern tube shaft installation effectiveness.
