Description
Technical field
The present invention relates to shipbuilding technical field, a kind of be assigned in the very heavy of stern tube shaft for being scraped by propeller for vessels
Top.
Background technology
Now with the development of shipbuilding industry, propeller for vessels joins with scraping of stern tube shaft, install have become as together with crux
Operation, it is to use sledgehammer slowly to tap propeller and pack into stern tube shaft that traditional scraping is joined, and this mode exists the dynamics tapping sledgehammer
The potential safety hazard that the oar axle that controlling is poor and produces is destroyed, the labor intensity of workman is big simultaneously.Thus at present to propeller with
Scraping of stern tube shaft join, install and change into using simple annular hydraulic jack, as in figure 2 it is shown, but this simple annular hydraulic jack
Have that volume is big, Heavy Weight, operation inconvenience；On the other hand, the liquid injection port of this simple annular hydraulic jack is from cylinder body
Bottom is first drilled radially fluid path, then connects from the axial fluid path of inner part drilling, this operation be difficult to hold axially with radially fluid path
Direction, processing radially fluid path is longer simultaneously, and boring procedure drill bit is easy to split off and causes jack processing difficulties.Therefore to carry
Height is scraped and is joined efficiency, in addition to needs carry out structure improvement to existing Simple hydraulic jack, in addition it is also necessary to coordinate suitable auxiliary work
Tool carries out scraping joining.
Summary of the invention
The technical problem to be solved is to provide a kind of propeller for vessels and scrapes method of completing the square with stern tube shaft, and it can solve
Propeller for vessels and scraping of stern tube shaft are joined, are installed operation inconvenience, scrape and join the problem that efficiency is low and labor intensity is big.
In order to solve the problems referred to above, the technical scheme is that this propeller for vessels and stern tube shaft are scraped method of completing the square and included
There are following steps:
1), by propeller set through on stern tube shaft, it is inserted in annular hydraulic jack and frock nut successively and tightens；
2), start to beat hydraulic pressure by the low pressure hand pump connecting described annular hydraulic jack, after compression, described hand pump is rushed down
Liquid, pulls down described frock nut after the most manually tightening described frock nut and described annular hydraulic jack i.e. installs.
In technique scheme, more specifically scheme is: described annular hydraulic jack, includes circular cylinder, institute
It is set with annular piston in stating circular cylinder, between described circular cylinder and described annular piston, is provided with sealing ring, described ring
Offering breach between shape piston-top surface and side, described circular cylinder top connects the cylinder cap sealing described breach.
Further: described circular cylinder bottom offers the inlet of straight-through described circular cylinder inner chamber bottom surface；Described ring
Shape cylinder body external wall of upper portion is provided with leakage hole.
Further: described circular cylinder is threadeded with described cylinder cap, described circular cylinder is threadeded with described cylinder cap
Thread external diameter more than described annular piston external diameter, the thread position of described circular cylinder and the row contacted with described annular piston
Arc transition between the position of journey.
Further: described circular cylinder outer wall is provided with suspension ring.
Owing to using technique scheme, there is advantages that
1, during the present invention is mainly used in the scraping and join of the ships such as the hydraulic screw oar of customs supervisors and clerks ship, 68x, 61x, changes and used in the past
Sledgehammer taps urgent method, utilizes the flexible statical moment that annular hydraulic jack produces, turn frock nut and eject axle
Pin, thus avoid and tap the potential safety hazard that sledgehammer brings, effectively eliminate and tap the dynamics controlling difference of sledgehammer and produce
The potential safety hazard that oar axle is destroyed, and effectively reduce the labor intensity of workman.
2, cylinder body and the piston of the annular hydraulic jack that the present invention uses than originally diminishes with the jack volume of type,
Weight is also with minimizing, it is possible to reduce workmen scrapes timing demolition, installation physical demands, convenient operation.
3, the processing of the cylinder body liquid injection port of the annular hydraulic jack that the present invention uses changes traditional hydraulic jack
Liquid injection port is first to be drilled radially fluid path from the bottom of cylinder body, then carries out the mode connected from the axial fluid path of inner part drilling, solves this
Axial and radially fluid path the direction of the more difficult assurance of operation and the problem that radial direction fluid path is longer and boring procedure is easy to breaking of rod head.
Ensure the smoothness of fluid path, and the thread sizes in this hole is consistent with the size of general quick-make, facilitates liquid pipe
Install.
4, the annular hydraulic jack that the present invention uses is also provided with giving vent to mouth in outer wall of cylinder block design runlength position, prevents
Piston stroke is excessive, cylinder body stress deformation.
5, the gland thread internal diameter of the annular hydraulic jack cylinder body that the present invention uses is bigger than piston contact external diameter, cylinder body
Thread position and travel position must arc transition, it is to avoid installing rear O is cut bad, it is impossible to reach the effect sealed；
Outer wall at cylinder body is provided with suspension ring simultaneously, the taking and placing of convenient construction.
