Description

Technical Field

[0001] This invention relates to the field of shipbuilding, and more specifically, to a rolling rudder platform for mounting ship rudders. Background Technology

[0002] The rudder is the ship's steering device. Rudders are usually made of steel, are large in size, have a high center of gravity, are heavy, and have a small cross-sectional width. Ship rudders require high installation precision, but due to their great weight (often exceeding 100 tons), positioning them is difficult. Therefore, there is an urgent need for a rudder platform that can be used to adjust the position of the rudder. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a rolling rudder platform for mounting ship rudders, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A rolling rudder platform for mounting a ship's rudder includes a base, a rolling platform being positioned in the center of the base via a groove, and rudder platform towers being provided on both sides of the rolling platform on the base.

[0006] Multiple ball bearing devices are fixedly arranged in a longitudinal and transverse pattern on the upper surface of the rolling platform. Each ball bearing device includes a cylindrical ball bearing base that is vertically fixed to the upper surface of the rolling platform, and a ball bearing is disposed inside the ball bearing base. A ball bearing cover plate is provided on the upper surface of the ball bearing base, and a cover plate opening is provided in the center of the ball bearing cover plate, with the top of the ball bearing protruding from the cover plate opening.

[0007] Multiple adjusting hydraulic cylinders are installed at the edge of the upper surface of the rolling platform, with the extension and retraction ends of the adjusting hydraulic cylinders perpendicular to the edge of the rolling platform and facing inward.

[0008] Each rudder platform tower consists of a bottom tower section, a middle tower section, and an upper tower section;

[0009] The bottom tower section includes a bottom horizontal base plate and a bottom horizontal top plate. The four corners of the bottom base plate and the four corners of the bottom top plate are connected by four bottom columns. The first middle-level entrance is opened in the middle of the bottom top plate, and an inclined bottom staircase is set from the edge of the bottom base plate to the edge of the first middle-level entrance.

[0010] The middle tower section includes a horizontal middle floor slab at the bottom and a horizontal middle top slab at the top. The four corners of the middle floor slab and the four corners of the middle top slab are connected by four middle columns. A second middle entrance is opened in the middle of the middle floor slab, and a first upper entrance is opened in the middle of the middle top slab. An inclined middle staircase is provided from the edge of the middle floor slab to the edge of the first upper entrance.

[0011] The upper tower section includes a horizontal upper base plate at the bottom and a horizontal upper top plate at the top. The four corners of the upper base plate and the four corners of the upper top plate are connected by four upper columns. A second upper entrance is opened in the middle of the upper base plate, and a top entrance is opened in the middle of the upper top plate. An inclined upper staircase is provided from the edge of the upper base plate to the edge of the top entrance.

[0012] The bottom top plate is exactly the same as the middle bottom plate, and the middle bottom plate overlaps and is fixed on top of the bottom top plate;

[0013] The middle top plate is exactly the same as the upper bottom plate, and the upper bottom plate overlaps and is fixed on top of the middle top plate;

[0014] The upper surface of the upper roof slab is also equipped with a top-level guardrail that surrounds the edge of the upper roof slab;

[0015] Both rudder platform towers are rectangular in structure and their lengths are parallel to each other. The two rudder platform towers are arranged along their width.

[0016] Each rudder platform tower's middle and upper tower sections are equipped with rudder blade adjustment screws that are horizontally oriented towards another rudder platform tower along the width direction of the rudder platform tower.

[0017] The middle column and the upper column are connected to a set screw connecting block, and the set screw connecting block is provided with a set screw thread hole; the rudder blade adjusting set screw passes through the set screw thread hole.

[0018] The sides of the bottom tower section are equipped with a bottom reinforcement structure.

[0019] The four sides of the middle tower section are equipped with a hollowed-out middle reinforcement structure.

[0020] The upper tower section has a hollowed-out upper reinforcement structure on all four sides.

[0021] Stair railings are installed on both sides of the ground floor staircase, the middle floor staircase, and the upper floor staircase.

[0022] Each rudder platform tower has two intermediate rudder blade adjusting screws on its middle tower section, with the two intermediate rudder blade adjusting screws located next to the two intermediate columns respectively.

[0023] Each rudder platform tower has two upper rudder blade adjusting screws on its upper tower section, with the two upper rudder blade adjusting screws located next to the two upper columns respectively.

[0024] The advantages of this invention compared to existing technologies lie in its tower-shaped rudder platform, designed to address the large size of rudders. This platform allows multiple personnel to observe the rudder's installation position from both the bottom and higher positions. Furthermore, it enables simultaneous adjustment of the rudder's position using both the rudder blade adjusting screws and the hydraulic cylinder. Since the rudder is placed on a ball bearing mechanism, its movement is very effortless. Therefore, this invention enables relatively effortless and precise position adjustment of rudders with large weight and size, proving highly convenient and effective, and filling a gap in rudder installation position adjustment technology.
