[0029] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0030] Reference Figure 1The rudder system structure of the first embodiment of the present invention includes: a stern 100, provided with a rudder hanging arm 130, a steering gear 110 and a rudder stock 120, the steering gear 110 is arranged on the upper side of the stern 100, the rudder stock 120 passes through the stern 100, the steering gear 110 drives the rudder stock 120 to rotate, the rudder hanging arm 130 protrudes in the horizontal direction to form a rudder button 131, and the rudder button 131 is rotatably provided with a rudder pintle 231; a rudder blade 200, connected to the rudder stock 120, and provided with a support portion 240 , a pintle 231 and an installation recess 201, the support portion 240 protrudes from the rudder blade 200, the installation recess 201 is located above the support portion 240, the rudder button 131 is placed in the installation recess 201, the pintle 231 passes through the rudder button 131 and is connected to the support portion 240, the pintle 231 and the rudder button 131 are rotatably connected, a box body 220 is detachably provided in the installation recess 201, the box body 220 is provided above the rudder button 131, and the box body 220 and the support portion 240 are both close to the rudder button 131.

[0031] When assembling, refer to Figure 6 , pre-install the rudder pintle 231 on the rudder blade 200 on the ground or in the workshop, and then transport the rudder blade 200 to the slipway for assembly with the stern 100. During assembly, the rudder blade 200 is driven to make the rudder button 131 enter the installation recess 201, and then the rudder pintle 231 is connected with the rudder button 131 from bottom to top, so that the rudder button 131 and the rudder pintle 231 are plugged and matched. At the same time, the upper side of the rudder blade 200 is connected to the rudder stock 120 upward. By arranging a detachable box 220 in the installation recess 201, the rudder button 131 is enlarged. The movable space in the installation recess 201 reduces the difficulty of operation, thereby improving the operating efficiency. After the rudder button 131 is connected to the rudder pin 231, the box body 220 is welded to the rudder blade 200. The box body 220 is located above the rudder button 131, and the assembly of the rudder system structure can be completed. The box body 220 and the support part 240 cooperate to position the rudder button 131, and at the same time make the structure between the rudder blade 200 and the stern 100 compact, and the operation is simple, shortening the installation period, improving the utilization rate of the slipway, saving time and cost.

[0032] Furthermore, it is understood that, with reference to Figure 7 When disassembling the rudder blade 200, by removing the box body 220 and unlocking the rudder blade 200 and the rudder stock 120, the rudder blade 200 can be operated to move downward, so that the rudder pintle 231 is separated from the rudder button 131. During the disassembly process, there is no need to disassemble the rudder pintle 231, which is convenient for disassembly, shortens the disassembly time of the rudder blade 200, facilitates maintenance and replacement, and saves time and cost.

[0033] It is understandable that, referring to Figure 1A rudder stock socket 211 is provided on the upper side of the rudder blade 200. The rudder stock socket 211 is provided with a first hydraulic nut 213. The first hydraulic nut 213 fastens the rudder stock 120 to the rudder stock socket 211. The rudder stock socket 211 is installed on the upper side of the rudder blade 200, the rudder stock 120 is docked with the rudder stock socket 211, and then the rudder stock 120 is locked to the rudder stock socket 211 via the first hydraulic nut 213. This facilitates assembly and disassembly. By loosening the first hydraulic nut 213, the rudder stock 120 can be separated from the rudder stock socket 211, which is convenient and quick. The rudder stock 120 is connected to the rudder stock socket 211 via the rudder stock socket 211, which facilitates maintenance.

[0034] It is understandable that, referring to Figure 3 The rudder blade 200 is provided with a first mounting slot, which mates with the rudder stock socket 211. A first relief slot is defined in the bottom wall of the first mounting slot, with first baffles 212 mounted at both ends of the first relief slot. The first mounting slot facilitates positioning the rudder stock socket 211 on the rudder blade 200, enabling rapid assembly and improving efficiency. Furthermore, the first relief slot allows the rudder stock 120 to pass through the rudder stock socket 211 and be locked by the first hydraulic screw, which is lower than the first relief slot. This facilitates operation and reduces difficulty. The first baffle 212 then shields the first relief slot, protecting the first hydraulic nut 213 while preserving the appearance of the rudder blade 200.

[0035] Similarly, it is understandable that, with reference to Figure 1 and Figure 3 The rudder blade 200 is provided with a pintle seat 232, which is located below the rudder knob 131. The pintle seat 232 is provided with a second hydraulic nut 233, which fastens the pintle 231 to the pintle seat 232. The pintle seat 232 is connected to the pintle 231, and then the second hydraulic nut 233 is used to lock the pintle 231 to the pintle seat 232. This is simple and quick. Moreover, by pre-installing the pintle 231 on the pintle seat 232, it can be done on the ground or in a workshop, reducing the occupation of the slipway, extending the service life of the slipway, and saving costs.

[0036] It is understandable that, referring to Figure 3The support portion 240 defines a second mounting slot that mates with the pintle holder 232. A second relief slot is defined in the bottom wall of the second mounting slot, with second baffles 234 disposed at both ends of the second relief slot. Installing the pintle holder 232 into the second mounting slot allows for quick positioning of the pintle holder 232, improving assembly efficiency. Furthermore, after the pintle 231 passes through the pintle holder 232 through the second relief slot, the lower end of the pintle 231 is connected to the second hydraulic nut 233, facilitating operation and improving efficiency. Furthermore, after tightening the second hydraulic nut 233, the second relief slot is closed by installing the second baffle 234, protecting the second hydraulic nut 233 while maintaining the integrity of the rudder blade 200 and enhancing its aesthetic appearance.

[0037] It is understandable that, referring to Figure 1 The rudder button 131 is arranged between the box body 220 and the rudder pintle socket 232. The box body 220 and the rudder pintle socket 232 cooperate to position the rudder button 131. The rudder pintle socket 232 and the box body 220 are close to the rudder button 131. The structure between the rudder blade 200 and the stern 100 is more compact and the appearance is more beautiful.

[0038] It is understandable that, referring to Figures 2 to 4 The pintle 231 has a tapered head 235 at its lower end, and the pintle receptacle 232 has a tapered hole. The tapered hole mates with the tapered head 235, and the tapered head 235 engages with the tapered hole. When the pintle 231 is inserted into the tapered hole from top to bottom, the tapered head 235 automatically mates with the inner wall of the tapered hole, achieving a self-locking relationship between the tapered head 235 and the tapered hole. This locks the pintle 231 to the pintle receptacle 232, stabilizes the pintle 231, and improves the seismic resistance of the rudder blade 200.

[0039] It is understandable that, referring to Figure 5 The inner side of the box body 220 is hollow, and the box body 220 is U-shaped as a whole, which reduces the weight of the box body 220, facilitates transportation and assembly, and improves efficiency.

[0040] Reference Figure 6 The assembly method of the second embodiment of the present invention, applied to the rudder system structure of the first embodiment of the present invention, comprises the following steps:

[0041] S1. Install the pintle 231 onto the rudder blade 200;

[0042] S2, hoisting the rudder blade 200 to the stern 100, and then translating the rudder blade 200 so that the rudder knob 131 is located above the rudder pintle 231;

[0043] S3, aligning the rudder pintle 231 with the mounting hole on the rudder knob 131;

[0044] S4: Drive the rudder blade 200 upward, insert the rudder pintle 231 into the mounting hole of the rudder knob 131, and connect the rudder blade 200 to the rudder stock 120;

[0045] S5. Move the box body 220 to above the steering knob 131 , and then weld the box body 220 into the installation recess 201 .

[0046] An embodiment of the present invention provides a rudder system structure and an assembly method. A detachable box 220 is provided on a rudder blade 200. A rudder pintle 231 is pre-installed on the rudder blade 200. A rudder knob 131 is then docked with the rudder pintle 231. Meanwhile, the rudder blade 200 is connected to a rudder stock 120. This increases the movable space of the rudder knob 131 and reduces the difficulty of operation. The box 220 is then installed on the rudder blade 200 so that the box 220 is located above the rudder knob 131. This completes the assembly of the rudder system structure. The box 220 cooperates with a support portion 240 to position the rudder knob 131. This makes the structure between the rudder blade 200 and the stern 100 compact, simplifies operation, shortens the installation period, improves slipway utilization, and saves time and cost.

[0047] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary counting personnel in this technical field, several improvements and substitutions can be made without departing from the counting principle of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
