Description

Technical Field

[0001] The utility model belongs to the technical field of thrusters and relates to a folding structure of a cruise ship thruster. Background Art

[0002] The thruster for a cruise ship is generally placed at the stern. It is a tool that converts energy into energy for pushing the fluid through a propeller to make the ship move forward. Large ships are equipped with thrusters. However, due to the large size of the thruster, it occupies a large space. When the thruster is not needed, hanging it at the stern affects the storage and transportation of the hull.

[0003] In view of the above problems, people have developed a folding marine thruster disclosed in Chinese Patent Application [Authorized Publication No.: CN211364898U], which includes a machine base that can be fixed on the hull. A mounting frame that can rotate relative to it is connected to the machine base. A steering assembly that can rotate relative to it and is used to adjust the sailing direction is penetrated through the mounting frame. The steering assembly includes a steering rod that is penetrated through the mounting frame and can rotate relative to the mounting frame and can slide relative to the mounting frame. A driving motor for installing a propeller is provided at the lower end of the steering rod. A rotating device for driving the steering assembly to rotate relative to the mounting frame is provided on the mounting frame. A flipping device for driving the mounting frame to drive the steering assembly to flip and fold relative to the machine base is provided between the mounting frame and the machine base. A driving device for driving the steering rod to slide relative to it is provided on the mounting frame.

[0004] The above structure drives the mounting frame to drive the steering assembly to flip and fold relative to the machine base through a flipping device. The flipping device is provided with a plurality of components such as gears. The installation accuracy requirements of the gears are relatively high, and the installation is relatively complex. Precise positioning is required between each component, which improves the installation difficulty and processing difficulty. And components such as a driving motor need to be installed, resulting in a relatively large volume of the entire folding device, increasing the storage space of the folded thruster and causing inconvenience in storage. Summary of the Utility Model

[0005] The purpose of the present utility model is to address the above problems existing in the prior art and propose a folding structure of a cruise ship thruster. The technical problem to be solved by the present utility model is: how to solve the problem that the existing folding structure of the thruster has a relatively large storage volume due to the setting of a driving motor and gears.

[0006] The purpose of the present utility model can be achieved by the following technical solutions:

[0007] A folding structure of a cruise ship propeller. The propeller includes two mounting plates that are fixedly arranged on the hull, are relatively arranged left and right, and are connected to each other. The folding structure is characterized in that it includes a hollow connecting rod that penetrates and is fixedly connected to the two mounting plates. A mounting seat that can rotate circumferentially along the hollow connecting rod is sleeved on the hollow connecting rod. A propeller is fixedly connected to the lower end of the mounting seat. A guide rod is slidably connected in the hollow connecting rod. One end of the guide rod is connected with a limiting plate. A plurality of positioning ports are formed on the mounting seat. A positioning block that protrudes from the limiting plate and penetrates through one of the mounting plates is formed. One end of the positioning block penetrates through the mounting plate and axially embeds into one of the positioning ports to lock the mounting seat and the mounting plate. When the guide rod moves axially, it can push the positioning block of the limiting plate out of the corresponding positioning port.

[0008] Working principle: By installing the hollow connecting rod on the two mounting plates, a mounting seat is sleeved on the hollow connecting rod, a propeller is fixedly connected to the lower end of the mounting seat, and a guide rod is slidably connected to the hollow connecting rod. When the cruise ship propeller is in normal use, the positioning block on the limiting plate penetrates through one of the mounting plates, and the end part penetrates through the positioning block and embeds into a positioning port of the mounting seat, locking the mounting seat and the mounting plate, so as to realize the normal use of other components such as the propeller at the lower end of the mounting seat. When the cruise ship propeller needs to be stored, the guide rod can be axially moved until it pushes the positioning block on the limiting plate to move out of the corresponding positioning port, completing the unlocking of the mounting seat and the mounting plate. At this time, the mounting seat can rotate circumferentially along the hollow connecting rod. Generally, after rotating to the horizontal position, the guide rod is axially moved again to make the positioning block of the limiting plate embed into the corresponding positioning port, realizing the locking of the mounting seat and the mounting plate. Thus, by folding the mounting seat, the storage of the mounting seat is made convenient.

[0009] The above structure realizes the folding storage of the mounting seat through components such as the hollow connecting rod, the limiting plate, and the guide rod. And two mounting plates that are arranged opposite to each other left and right are adopted, making the installation of the mounting seat and the hollow connecting rod more convenient. And through structures such as the coaxially arranged hollow connecting rod, the limiting plate, and the guide rod, the hollow connecting rod, the limiting plate, and the guide rod and other structures are all arranged between the mounting seat and the two mounting plates, improving the space utilization rate and integration degree. And components such as a driving motor are not adopted, making the overall structure simple, the operation convenient, and the required storage space smaller.

[0010] In the folding structure of the above-mentioned cruise ship propeller, one end of the guide rod is connected with an adjusting push rod that is partially located outside the hollow connecting rod. A return spring is sleeved on the guide rod. One end of the return spring abuts against the hollow connecting rod, and the other end abuts against the adjusting push rod. The return spring has an elastic force that always pushes the adjusting push rod to move axially outward.

[0011] By setting the reset spring, it can be ensured that after the positioning block is embedded in the corresponding positioning port, the elastic force of the reset spring can push the adjusting push rod, and the adjusting push rod drives the guide rod and the limit plate to move synchronously, thereby realizing axial limitation of the positioning block and preventing the positioning block from falling out of the corresponding positioning port, thereby improving the convenience and stability of operation. The reset spring is sleeved on the guide rod and located in the hollow connecting rod, which rationally utilizes the space between the two to improve the space utilization and integration of the folding structure.

[0012] In the above-mentioned folding structure of the cruise ship propeller, the middle protrusion of the limit plate forms a guide column, the guide column is slidably connected in the hollow connecting rod, and the outer wall of the guide column is in contact with the inner wall of the hollow connecting rod.

[0013] The setting of the guide column makes the limit plate more stable when sliding along the hollow connecting rod, avoids circumferential deviation of the limit plate, and improves the stability of the folding structure.

[0014] In the above-mentioned folding structure of the cruise ship propeller, a mounting groove is provided on the outer side wall of one of the mounting plates, the limit plate can be arranged in the mounting groove and the positioning block is passed through the mounting plate.

[0015] The opening of the mounting groove allows the mounting plate to be located in the mounting groove when the positioning block of the limit plate is embedded in the positioning opening, thereby improving the stability of the setting of the limit plate, and by passing the positioning block through the mounting plate, the positioning block on the limit plate only needs to be embedded in the corresponding positioning opening during movement, thereby further improving the stability of the positioning block and the convenience of operation.

[0016] In the above-mentioned folding structure of the cruise ship propeller, the mounting seat has a connecting tube sleeved on a hollow connecting rod, and a plurality of the above-mentioned positioning openings are opened on the outer wall of one end of the connecting tube, and the positioning openings are distributed circumferentially along the end of the connecting tube.

[0017] The setting of the connecting tube enhances the stability of the connection between the mounting seat and the hollow connecting rod, and when the mounting seat rotates, the outer wall of the hollow connecting rod can support and guide the connecting tube of the mounting seat, making the rotation of the mounting seat more stable, and the position setting of the positioning port facilitates the rapid positioning of the positioning block on the limit block.

[0018] In the above-mentioned folding structure of the cruise ship propeller, a limiting step is provided on the outer wall of one end of the hollow connecting rod, one of the mounting plates has a limiting portion abutting against the limiting step, and a slot for setting a compression spring is provided on the outer wall of the hollow connecting rod, and the compression spring presses the limiting portion against the limiting step.

[0019] The limiting part of one of the mounting plates is sleeved on the hollow connecting rod, and the end of the limiting part is abutted against the limiting step, and then the compression spring is set in the bayonet. The compression spring can press the limiting part against the limiting step, so that the connection between the hollow connecting rod and the mounting plate is more stable, and the structure is simple and easy to install.

[0020] In the above-mentioned folding structure of the cruise ship propeller, the adjusting push rod has a columnar sliding part, the sliding part is slidably connected in the hollow connecting rod, and the outer wall of the sliding part is in contact with the inner wall of the hollow connecting rod, and the end of the return spring is in contact with the end of the sliding part.

[0021] On the one hand, the sliding part can guide the axial movement of the adjusting push rod, and on the other hand, it abuts against the reset spring, so that the setting of the reset spring does not affect the movement of the adjusting push rod, thereby ensuring the stable use of the folding structure.

[0022] In the above-mentioned folding structure of the cruise ship propeller, a projection is formed on the inner side wall of the middle part of the hollow connecting rod to form a limit stop shoulder, and one end of the return spring abuts against the limit stop shoulder.

[0023] The setting of the limit stop shoulder makes the setting of the return spring simpler and facilitates the installation of the folding structure.

[0024] Compared with the prior art, the folding structure of the cruise ship propeller has the following advantages: the folding storage of the mounting seat is realized by means of components such as the hollow connecting rod, the adjusting push rod, the limit plate, the guide rod and the return spring, and two mounting plates are arranged opposite to each other on the left and right, so that the installation of the mounting seat and the hollow connecting rod is easier, and because the return spring, the push rod and the limit plate are used in coordination, the installation difficulty is greatly reduced, and the operation is convenient and the structure is simple. The mounting seat is sleeved on the hollow connecting rod, which increases the contact area, enhances the connection strength of the mounting seat, and improves the overall space utilization. The folding structure is small in size and easy to store. While improving the convenience of use and installation of the folding structure, it also ensures the stability of the mounting seat.

DETAILED DESCRIPTION

[0031] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0032] like Figure 1 As shown, the folding structure of the cruise ship propeller comprises two mounting plates 1 fixed on the hull, which are arranged opposite to each other and connected to each other.

[0033] Specifically, Figures 1-5 As shown, the folding structure includes a hollow connecting rod 2 that is passed through and fixedly connected to two mounting plates 1, a mounting seat 3 that can rotate along the circumferential direction of the hollow connecting rod 2 is sleeved on the hollow connecting rod 2, a propeller 31 is fixedly connected to the lower end of the mounting seat 3, a guide rod 4 is slidably connected inside the hollow connecting rod 2, a return spring 5 is sleeved on the guide rod 4, one end of the guide rod 4 is connected to an adjustment push rod 6 that is partially located outside the hollow connecting rod 2, and the other end is connected to a limiting plate 7, one end of the return spring 5 is against the hollow connecting rod 2, and the other end is against the limit plate 7. The end abuts against the adjusting push rod 6, a plurality of positioning holes 32 are opened on the mounting seat 3, and a positioning block 71 is formed on the limit plate 7 and is penetrated on one of the mounting plates 1. One end of the positioning block passes through the mounting plate 1 and is embedded in one of the positioning holes 32 to lock the mounting seat 3 and the mounting plate 1. The adjusting push rod 6 can move axially to push the positioning block 71 of the limit plate 7 out of the corresponding positioning hole 32 and compress the reset spring 5. The reset spring 5 has an elastic force that always pushes the adjusting push rod 6 to move axially outward.

[0034] Working principle: A hollow connecting rod 2 is connected to the mounting plate 1, a mounting seat 3 is sleeved on the hollow connecting rod 2, a propeller 31 is fixedly connected to the lower end of the mounting seat 3, and a guide rod 4 is slidably connected to the hollow connecting rod 2. When the cruise ship propeller is in normal use, a positioning block 71 on the limit plate 7 is passed through one of the mounting plates 1, and the end passes through the positioning block and is embedded in a positioning hole 32 of the mounting seat 3, and the guide rod 4 is driven to move axially toward the direction of the other mounting plate 1 by adjusting the push rod 6 through the return spring 5. The elastic force of the return spring 5 limits the limit plate 7, so that the positioning block 71 on the limit plate 7 is always located in the positioning hole 32, thereby realizing the locking of the mounting seat 3 and the mounting plate 1, thereby realizing the normal use of other components such as the propeller 31 at the lower end of the mounting seat 3. When the cruise ship propeller needs to be stored , the adjusting push rod 6 can be pushed in the direction of the mounting seat 3, and the movement of the adjusting push rod 6 synchronously compresses the reset spring 5, and the adjusting push rod 6 drives the limiting plate 7 to move synchronously axially through the guide rod 4, so that the positioning block 71 on the limiting plate 7 moves from the corresponding positioning hole 32, completing the unlocking of the mounting seat 3 and the mounting plate 1. At this time, the mounting seat 3 can rotate circumferentially along the hollow connecting rod 2. Generally, after rotating to the horizontal position, the adjusting push rod 6 is released, and the reset elastic force of the reset spring 5 drives the adjusting push rod 6 to move in the direction away from the mounting seat 3, and the limiting plate 7 moves synchronously with the adjusting push rod 6 through the guide rod 4. The limiting plate 7 moves to the positioning block 71 and is embedded in another positioning hole 32, thereby realizing the locking of the mounting seat 3 and the mounting plate 1, thereby realizing the convenient storage of the mounting seat 3 by folding the mounting seat 3.

[0035] The above structure realizes the folding storage of the mounting seat 3 through the hollow connecting rod 2, the adjusting push rod 6, the limit plate 7, the guide rod 4 and the return spring 5 and other components, and adopts two mounting plates 1 arranged opposite to each other on the left and right, which makes the installation of the mounting seat 3 and the hollow connecting rod 2 easier, and because the return spring 5, the push rod and the limit plate 7 are used in cooperation, the installation difficulty is greatly reduced, and the operation is convenient and the structure is simple. The mounting seat 3 is sleeved on the hollow connecting rod 2, which increases the contact area and enhances the connection strength of the mounting seat 3. While improving the convenience of use and installation of the folding structure, it also ensures the stability of the mounting seat 3. Through the coaxially arranged hollow connecting rod 2, the limit plate 7 and the guide rod 4 and other structures, the hollow connecting rod 2, the limit plate 7 and the guide rod 4 and other structures are all arranged between the mounting seat 3 and the two mounting plates 1, which improves space utilization and integration, and does not use components such as driving motors, which makes the overall structure simple, easy to operate, and requires less storage space.

[0036] like Figure 3 and Figure 4As shown, a middle part of the limit plate 7 protrudes to form a guide post 72. The guide post 72 is slidably connected within the hollow connecting rod 2, and an outer sidewall of the guide post 72 is in contact with an inner sidewall of the hollow connecting rod 2. An installation sink 11 is formed on an outer sidewall of one of the mounting plates 1. The limit plate 7 can be arranged within the installation sink 11 and a positioning block 71 penetrates through the mounting plate 1.

[0037] As Figure 4 and Figure 5 shown, the mounting seat 3 has a connecting pipe 33 sleeved on the hollow connecting rod 2. A plurality of the above-mentioned positioning ports 32 are formed on an outer sidewall of one end of the connecting pipe 33. The positioning ports 32 are distributed circumferentially along an end portion of the connecting pipe 33. A limit step 21 is formed on an outer sidewall of one end of the hollow connecting rod 2. One of the mounting plates 1 has a limiting portion 12 abutted against the limit step 21. A bayonet 22 for arranging a compression spring 8 is formed on an outer sidewall of the hollow connecting rod 2. The compression spring 8 presses the limiting portion 12 against the limit step 21.

[0038] As Figure 3 and Figure 4 shown, the adjusting push rod 6 has a columnar sliding portion 61. The sliding portion 61 is slidably connected within the hollow connecting rod 2, and an outer sidewall of the sliding portion 61 is in contact with an inner sidewall of the hollow connecting rod 2.
