Along with the ocean engineering boats and ships develop towards maximization, high-power, the high-power full-rotating rudder paddle that can satisfy ship power, positioning requirements simultaneously also is more and more widely used.For load-carrying capacity, propulsion coefficient and the bitt thrust that improves high-power full-rotating rudder paddle, be equipped with the selection that conduit becomes a best.
At present, traditional high-power full-rotating rudder paddle is when General Maintenance, and after must earlier conduit being disassembled, work such as the blade of just polishing, replacing blade seal ring after all handling labors are accomplished, also need be reinstalled conduit.This has not only wasted great amount of time, simultaneously because the guide-tube structure of high-power full-rotating rudder paddle is complicated, heavy, brings inconvenience for the lifting work of installing/dismounting, has increased the dismounting difficulty.
The Chinese patent Granted publication number is CN2832659Y; Granted publication day is that the utility model patent on November 1st, 2006 discloses a kind of combined lateral propelling unit; Axle drive shaft one side of this utility model on gear case assembly is provided with the gear case flange; The conduit flange that the gear case flange is provided with on bolt and conduit is connected, and the prop shaft in the gear case assembly does not have the binding axial organ through hydraulic pressure and is connected with the propeller hub assembly, and it is inner that the displacement oil cylinder is arranged on the propeller hub of propeller hub assembly.Though this utility model has reduced processing and manufacturing and mounting hardness, structure is compact more, when carrying out General Maintenance; Still need from conduit, to take apart together with the propeller hub assembly of blade earlier; Just can carry out General Maintenance then, not only maintenance time is longer, and the dismounting difficulty is higher.
Summary of the invention
The objective of the invention is to overcome the maintenance time that exists in the prior art and grow, dismantle difficulty problem of higher and defective, provide a kind of maintenance time to lack, dismantle the lower high-power full-rotating rudder paddle of difficulty and the method for dismounting of blade thereof.
For realizing above purpose; Technical solution of the present invention is: a kind of high-power full-rotating rudder paddle of carrying pipe; Comprise conduit, lower teeth roller box, propeller hub body, crank pin disk and cast-in-block blade and blade flange, said conduit is connected through the upper end of conduit bolt with the lower teeth roller box, and blade is rotated in the conduit; The blade flange is captiveed joint with crank pin disk through the blade bolt, and crank pin disk and propeller hub body fasten;
The set inside of said blade flange has jacking system; This jacking system comprises piston, baffle plate and backing plate; One end of said piston is arranged in blade flange inner chamber, and the backing plate that is provided with in the other end and the crank pin disk seam is connected, and the be connected both sides at position of piston, backing plate respectively are provided with a baffle plate; This baffle plate is captiveed joint with crank pin disk through screw; The cavity that is positioned at piston upper end in the said blade flange inner chamber communicates through the spiro pluging hole that is provided with on inclined oil hole of air and the blade bolt hole sidewall, is provided with plug screw in the spiro pluging hole, is provided with the blade bolt in the blade bolt hole; Said blade flange is provided with two holes for hoist, and the center of gravity of blade is positioned on the center connection lead of two holes for hoist in the projection on the blade Flange Plane;
The blade tip of said blade and the minimum clearance between conduit are L1, and the stroke of said piston is L2, and the distance between said blade Flange Plane and the external circle of propeller hub is L3, and the distance between said blade Flange Plane and crank pin disk seam is L4, and L1 ﹥ L2 ﹥ L3 ﹥ L4.
Said crank pin disk is connected with the blade flange through blade pilot pin, blade bolt, and the blade pilot pin is bolted on the crank pin disk in the pin-guide hole through pilot pin; Be provided with the O RunddichtringO between the side of said piston upper end and the blade flange inner chamber.
A kind of method for dismounting of blade of high-power full-rotating rudder paddle of above-mentioned carrying pipe, said method for dismounting may further comprise the steps successively:
The first step: earlier lifting tool is installed on conduit, is taken away two corrosion-resistant steel plug screws in the hole for hoist again, then lifting tool is connected with two holes for hoist, again the blade bolt on the blade flange is dismantled from the outside; Said crank pin disk is connected with the blade flange through the blade bolt;
Second step: above-mentioned dismounting is taken off plug screw earlier after finishing, and to inclined oil hole of air, squeezes into pressure oil from spiro pluging hole again; The pressure oil of squeezing into flows in the cavity in the blade flange inner chamber, and subsequently, the pressure oil in the cavity presses down piston; Simultaneously the blade flange is by jack-up, when jack-up stroke during greater than the distance L 4 between blade Flange Plane and crank pin disk seam, and blade flange and crank pin disk disengaging; Continue to squeeze into pressure oil, when jack-up stroke during greater than the distance L 3 between blade Flange Plane and the external circle of propeller hub, blade flange and propeller hub body break away from; Promptly stop to squeeze into pressure oil after the disengaging; Control lifting tool again blade flange, blade are sling, and level puts down blade flange and blade after outwards removing certain distance, i.e. dismounting this moment first blade that finish;
The 3rd step: earlier with propeller hub body Rotate 180 degree,, so repeatedly, finish, can accomplish the dismounting of blade of the high-power full-rotating rudder paddle of carrying pipe at this moment until all blades dismountings again with the same method for dismounting dismounting and the blade of first symmetry.
In the said first step, said crank pin disk is connected with the blade flange through blade pilot pin, blade bolt, when to the blade bolt on the blade flange when dismantle the outside, simultaneously the pilot pin bolt on the blade flange, blade pilot pin are dismantled from the outside.
The quantity of said blade is four, and evenly is provided with along same circumference.
The installation process of blade is opposite with the unloading process step, but principle is similar with method, can in conduit, carry out equally.
