Embodiment 1

[0040] Embodiment 1 is the installation method of the rudder and paddle device from top to bottom

[0041] Such as figure 1 , 3 , 4, 6, and 7, a method for installing a full-turn rudder propeller device from top to bottom includes the following steps:

[0042] 1) Make casing flange 1, which includes base flange 1.1 and casing body 1.2, where the thickness of base flange 1.1 has a machining allowance of about 15mm, and the inner hole of base flange 1.1 is processed to finished size D1. The height of the casing 1.2 should reserve about 100mm from the lowest point of the bottom plate protruding from the casing for support and clamping during vertical lathe processing, and the excess part is cut off along the line of the bottom after reset;

[0043] 2) The intermediate bearing base near the rudder propeller base has been welded. For electric propulsion full-turn rudder propellers, the base of the propulsion motor has been welded. On this basis, the main body of the ship is bui...

Embodiment 2

[0057] Embodiment 2 is that the rudder and paddle device is installed from bottom to top

[0058] Such as figure 2 , 3 , 5, 8, and 9, a method for installing a full-turn rudder propeller device from bottom to top includes the following steps:

[0059] 1) Make casing flange 1, which includes base flange 1.1 and casing body 1.2, where the thickness of base flange 1.1 has a machining allowance of 15 mm, and the inner hole of base flange 1.1 is machined to Finished size D1. The height of the casing 1.2 of the casing should protrude about 100mm from the lowest point of the bottom plate of the casing, for support and clamping during vertical lathe processing, and the excess part is cut off along the line of the bottom of the ship after reset;

[0060] 2) The intermediate bearing base near the rudder propeller base has been welded. For electric propulsion full-turn rudder propellers, the base of the propulsion motor has been welded. On this basis, the main body of the ship is b...

Embodiment 3

[0075] Embodiment 3 is the installation method of rudder propeller unit assembly

[0076] Such as Figure 4 , Figure 5 The frustum cell design shown, corresponds to Figure 6 , Figure 8 The installation method of the rudder propeller shown. This process design provides favorable conditions for unit assembly. A method for assembling a full-turn rudder-propeller unit, the steps of which are as follows:

[0077] Step 1) ~ Step 9) are basically the same as Embodiment 1 and Embodiment 2, the difference is that in Step 9) the unit body of the conical table is finished, so that the installation mating surface, the groove of the sealing ring ( Figure 5 The installation mating surface of the lower surface of the conical platform unit body shown is not provided with a sealing ring groove) and all screw holes on the flange of the base meet the design requirements, and then the full-turn rudder propeller 5 is unit assembled with the conical platform unit body ;

[0078] 10) Build...

Abstract

The invention discloses a full rotation steering oar device installation method. A hull base of a full rotation steering oar which is installed in a trunk flange mode is cut into tapered unit bodies (indicated as the figure). The tapered unit bodies are transported to a workshop and high-precision mounting matching surfaces, screw holes and seal ring grooves are machined on the tapered unit bodies through a large vertical lathe. Next, the machined tapered unit bodies are lifted on a ship and replaced according to cutting steel marks and then the steering oar is installed so as to meet the requirement for shafting layout design, installation quality of the steering oar and sealing reliability. The full rotation steering oar device installation method abandons a traditional construction method, is labor-saving and effort-saving, improves work efficiency, and saves expensive tooling equipment investment. Secondly, the machined tapered unit bodies can be assembled with the steering oar, and then lifted on the ship and carries out replacement and installation. Installation quality and work efficiency of the steering oar are further improved and requirements of modern shipbuilding are met.

Description

technical field [0001] The invention relates to a method for installing a rudder and propeller device, in particular to a method for installing a full-turn rudder and propeller device. Background technique [0002] More and more full-turn rudder and propeller devices are used in tugboats, port operation ships, ferries, engineering ships and offshore engineering ships with frequent maneuvering conditions. The diameter of the common base of the full-turn rudder propeller installed in a large-scale casing flange is 2~4m. For the processing of the installation matching surface of the corresponding casing flange and the installation of the full-turn rudder propeller, the rudder propeller factory has proposed very high requirements. Processing and installation accuracy requirements, the requirements are as follows: [0003] 1) Processing requirements for casing flanges [0004] The machining accuracy of the fitting surface of the casing flange is very high, and the flatness of t...
