Description

Technical Field

[0001] This utility model relates to the technical field of ship equipment, specifically a rudder blade mounting device with rudder fin. Background Technology

[0002] In existing technology, rudder fins (similar to the wings of a rudder blade) are energy-saving devices that recover energy from the propeller wake. They are installed on both sides of the rudder blade to absorb the rotational energy of the propeller wake, thus contributing to propulsion and energy saving. However, rudder blades with rudder fins typically have a width of about 4 meters, which existing installation devices cannot accommodate unless the width of the main platform is increased, but this would significantly reduce the rigidity of the main platform.

[0003] Currently, there is no good technical solution for installing rudder blades with rudder fins. All installations rely on on-site fabrication of lifting brackets on the hull and the gradual installation of the rudder blades with rudder fins using hand-operated hoists. The current traditional installation method of "fabricating lifting brackets and using hand-operated hoists" is time-consuming, labor-intensive, and damages the hull, which is not in line with the concept of green shipbuilding.

[0004] Therefore, there is an urgent need for a special mounting device for rudder blades with rudder fins, which can facilitate efficient installation and improve efficiency. Summary of the Invention

[0038] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0039] This utility model provides a rudder blade mounting device with rudder fins, including a main platform, see details below. Figure 1The difference between this and the existing technology is that: the main platform 1 is provided with a symmetrically arranged left operating table 2 and a right operating table 4. The left operating table is slidably connected to the main platform through a left slide table 3, and the right operating table is slidably connected to the main platform through a right slide table 5. By sliding the two slide tables, the distance between the left and right operating tables can be adjusted, so that the rudder blade with rudder fin can be placed, adjusted and operated in this device. A fine adjustment platform 6 is provided between the left and right slide tables. A rudder blade 7 is provided on the fine adjustment platform. Rudder fins 8 are provided on both sides of the rudder blade. Notch slots 10 for placing one end of the rudder fin are provided on the left and right operating tables. A traveling mechanism 9 is provided below the main platform.

[0040] In practice, a set of symmetrically arranged sliding left and right control panels are used to effectively operate and install the rudder blades with rudder fins. The left and right control panels have notches or slots for placing the rudder fins, allowing them to approach the rudder blades at close range for easy operation and adjustment. This device, without increasing the width of the main platform, allows for better and more effective installation and operation of rudder blades with rudder fins, improving work efficiency, reducing costs, and enhancing safety during operation.

[0041] Example 1

[0042] In this embodiment, as Figure 1 As shown, the main platform has a symmetrically arranged left and right operating platform. The left operating platform is slidably connected to the main platform via a left slide, and the right operating platform is slidably connected to the main platform via a right slide. By sliding the two slides, the distance between the left and right operating platforms can be adjusted, so that the rudder blade with rudder fins can be placed, adjusted, and operated in this device. A fine-tuning platform is provided between the left and right slides for placing the rudder blade. Rudder fins are provided on both sides of the rudder blade. The left and right operating platforms have notches for placing one end of the rudder fin, so that the left and right operating platforms can approach the rudder blade for effective observation and operation. A traveling mechanism is provided below the main platform to facilitate the delivery of the adjusted rudder blade to the next process.

[0043] Preferred, such as Figure 3 As shown, the left and right slides include a movable slide frame 31 and a guide rail 32 located below the slide frame. The slide frame contains a slide cylinder 33 and a matching slide cylinder piston rod. The slide cylinder is fixedly connected to the main platform via a slide cylinder seat 34, and the slide cylinder piston rod is fixedly connected to the slide frame. Driven by the slide cylinder, the slide frame slides back and forth, thereby causing the upper left and right operating platforms to slide.

[0044] Furthermore, a slide block 35 is provided on the outer edge of the slide frame to counteract the overturning moment of the slide frame, thereby improving stability and safety. Several hinged components 36 are provided on the top of the four sides of the slide frame. These hinged components consist of hinged bolts, washers, nuts, and cotter pins, and are installed on the slide frame to facilitate quick assembly and disassembly between the left and right operating tables and the slide frame, improving work efficiency.

[0045] Specifically, such as Figure 4 , Figure 5 As shown, the fine-tuning platform 6 includes a movable fine-tuning frame 61 and a load-bearing roller trolley 62 under the fine-tuning frame. The fine-tuning frame is welded from rectangular steel pipes. Inside the frame are fine-tuning cylinders 63 and matching piston rods. The fine-tuning cylinders are fixedly connected to the main platform via a fine-tuning cylinder seat 64, and the piston rods are fixedly connected to the fine-tuning frame. Driven by the fine-tuning cylinders, the fine-tuning frame slides effectively, facilitating the adjustment of the rudder blade position. Furthermore, a copper plate 65 is provided at the bottom of the fine-tuning frame, and the copper plate is slidably connected to the load-bearing roller trolley 62.

[0046] Example 2

[0047] In this embodiment, the main platform is provided with a symmetrically arranged left and right operating platform. The left operating platform is slidably connected to the main platform via a left slide, and the right operating platform is slidably connected to the main platform via a right slide. By sliding the two slides, the distance between the left and right operating platforms can be adjusted, so that the rudder blade with rudder fins can be placed, adjusted, and operated in this device. A fine-tuning platform is provided between the left and right slides for placing the rudder blade. Rudder fins are provided on both sides of the rudder blade. The left and right operating platforms are provided with notches and slots for placing one end of the rudder fin, so that the left and right operating platforms can approach the rudder blade for effective observation and operation. A traveling mechanism is provided under the main platform to facilitate the movement of the rudder blade for subsequent installation procedures.

[0048] Specifically, see Figure 6 , 7 8. The left and right operating platforms include a height-adjustable operating frame, which is a 2-4 layer stacked structure, with stairs 21 connecting the layers. Operators can access the operating platforms via the outer passageway 211 and the stairs, and the guardrails 212 on the stairs ensure the safety of the operators.

[0049] Furthermore, the operating frame includes a top movable frame 22, a middle frame 23, and a bottom frame. An operating platform lifting cylinder 24 and a guide rod 25 are provided between the top movable frame and the middle frame. The height of the top movable frame can be changed via the operating platform lifting cylinder. An operating platform 26 for the operator to stand on is provided on the top movable frame. Standing on the operating platform, the operator can perform various operations on the rudder blade, such as installing hydraulic nuts. The middle frame has notches 10 corresponding to the rudder fin positions, and diagonal braces 27 are provided near the notches to ensure the rigidity and strength of the overall structure. The middle frame is welded from H-beams and has two sets of rudder blade clamping cylinders 28 that cooperate with the rudder blade. Through the four sets of rudder blade clamping cylinders on the left and right operating platforms, the rudder blade can be reliably clamped, ensuring the safety and reliability of operation.

[0050] Preferred, such as Figure 9 , 10 As shown in Figure 11, the traveling mechanism 9 includes four rolling mechanisms located at the four corners of the main platform. Each rolling mechanism includes an inner and an outer sleeve. A roller assembly is located at the bottom of the rolling mechanism. A traveling lifting cylinder 92 is housed within the inner sleeve 91. The piston rod of the traveling lifting cylinder is connected to the outer sleeve 93 to drive the outer sleeve's lifting motion. The outer sleeve is fixedly connected to the main platform, and the inner sleeve is connected to the roller assembly via a flange 94. The inner and outer sleeves are welded from seamless steel pipes, and the outer sleeve and inner sleeve are guided by a guide copper sleeve 95 and a guide key 96. The movement of the piston rod of the traveling lifting cylinder drives the relative movement between the outer sleeve and the inner sleeve. The outer sleeve is fixedly connected to the main platform, thereby driving the main platform to perform lifting motion. Furthermore, the roller assembly includes a driving roller 97 and a driven roller 98. The driven roller is mounted on a driven shaft 99, and the driving roller is connected to the hydraulic motor reducer assembly 100.

[0051] Going further, Figure 2 As shown, the main platform has a U-shaped structure, with the electrical control box installation area 11 in the middle. The top of the electrical control box installation area is equipped with a fine-tuning platform installation plate 12, and the left slide installation plate 13 and the right slide installation plate 14 are on the sides respectively. Below the left and right slide installation plates is the frame area, which is composed of horizontal and vertical plates connected in an alternating manner. The four top corners of the main platform are equipped with a walking mechanism installation plate 15 and a walking mechanism installation hole 16.

[0052] During operation, when the left and right sliding platforms are adjusted to their maximum opening, the rudder fin can be avoided, allowing the rudder blade to fall normally onto the fine-tuning platform. After the rudder blade is in place, the opening of the left and right sliding platforms is adjusted to a suitable size until the operator can observe and operate the rudder blade. At this point, the left and right operating platforms can completely surround the rudder blade, and the rudder blade is stably held in place by four sets of rudder blade clamping cylinders. Finally, the position and height of the entire device are adjusted by the traveling mechanism, and in conjunction with the left and right adjustment of the fine-tuning platform, the rudder blade is transported to the rudder arm position, completing the rudder blade installation.

[0053] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications or substitutions should be considered within the protection scope of the present invention.
