Abstract
The utility model discloses a propeller installing tool, and relates to the technical field of ship manufacturing equipment. The propeller installing tool comprises a ring type hydraulic jack, wherein the middle part of the ring type hydraulic jack is provided with a through hole; the outer side of the through hole is provided with a cylinder sleeve; an annular groove is formed in one end face of the cylinder sleeve; an annular piston is installed in the annular groove in a clearance way; the side wall of the annular groove is provided with a seal ring; the bottom of the annular groove is provided with an oil passage for the circulation of hydraulic oil; the oil passage is communicated with the outer side face of the ring type hydraulic jack; the other end face of the cylinder sleeve is externally and movably connected with a tool nut in a resisting way. By the adoption of the propeller installing tool, the problems that the labor intensity of staff is great and the production efficiency is low in the course of assembling a propeller can be solved.
Description
Technical field
The utility model relates to shipbuilding equipment technical field, especially a kind of tool for mounting propeller of the installation for propeller for vessels.
Background technology
In traditional screw propeller fitting process, be all generally to adopt impact method that prop shaft is fully contacted with screw propeller, after finding accurately a little, upper frock nut, adopts special tooling spanner, urgent with the sledgehammer of 40 pounds, such assembling mode employee's labour intensity is large, and production efficiency is low.
Summary of the invention
The purpose of this utility model is to provide a kind of tool for mounting propeller, and it is large that it can solve in screw propeller fitting process staff labor intensity, the problem that production efficiency is low.
In order to address the above problem, the technical solution adopted in the utility model is: this tool for mounting propeller, comprise ring type hydraulic jack, the middle part of this ring type hydraulic jack is provided with through hole, described through hole arranged outside has cylinder sleeve, one of them end face of this cylinder sleeve has a circular groove, this circular groove internal clearance is equipped with annular piston, the sidewall of described circular groove is provided with seal ring, the bottom of described circular groove is provided with the oil circuit for hydraulic oil circulation, and described oil circuit is communicated with the lateral surface of described ring type hydraulic jack; The outer movable butt of another end face of described cylinder sleeve has frock nut.
In such scheme, more specifically scheme can also be: the gap between described cylinder sleeve and described annular piston is 0.25 millimeter.
Owing to having adopted technique scheme, compared with prior art, the beneficial effect having is the utility model: in screw propeller fitting process, adopt this tool for mounting propeller, greatly alleviated employee's labour intensity, improved production efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the cutaway view of ring type hydraulic jack.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Tool for mounting propeller shown in Fig. 1 and Fig. 2, a side activity butt of a side of ring type hydraulic jack 1 and frock nut 2; The body 3 of ring type hydraulic jack 1 is provided with through hole 1-1, this body 3 is provided with cylinder sleeve 1-2 round through hole 1-1, the sidewall of cylinder sleeve 1-2 has for the groove that seal ring 5 is installed, in cylinder sleeve 1-2, be provided with annular piston 4, between the bottom of cylinder sleeve 1-2 and the bottom of annular piston 4, be provided with the oil circuit for hydraulic oil circulation, this oil circuit stretches out outside body 3 and is connected with high-pressure oil pump from a side of body 3.Gap between cylinder sleeve 1-2 and annular piston 4 is 0.25 millimeter, so that annular piston 4 can move freely in cylinder sleeve 1-2.
In the time of work, first prop shaft 7 is penetrated in screw propeller 6, then ring type hydraulic jack 1 is inserted in to prop shaft 7, again frock nut 2 is screwed on prop shaft 7, make the bottom butt of frock nut 2 and ring type hydraulic jack 1, frock nut 2 is as a supporting seat, ring type hydraulic jack 1 is placed between frock nut 2 and screw propeller 6, provide a higher oil pressure by high-pressure oil pump to ring type hydraulic jack 1, promoting annular piston 4 moves, annular piston 4 promotes again screw propeller 6 and moves with respect to prop shaft 7, tapered of screw propeller 6 endoporus and prop shaft 7 are contacted, and then reach screw propeller 6 and scrape the object of joining or installing with prop shaft 7.
