[0042] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0043] This application provides a trailer system to solve the problem in related technologies where water tank test trailers are difficult to move along the Y-axis and rotate simultaneously while moving along the X-axis, making it difficult to conduct comprehensive verification.

[0044] Please see Figures 1-9 A trailer system includes a trailer main frame 1, a first track 2, a second track 3, a subframe assembly 4, a first drive unit 5, a second drive unit 6, a test frame 7, a third drive unit 8, a slewing mount 9, and a test slewing arm 20.

[0045] The trailer main frame 1 is a truss structure, with first rails 2 installed at both ends. The extension direction of the first rails 2 is perpendicular to the extension direction of the trailer main frame 1. The trailer main frame 1 moves along the first rails 2 via a first drive device 5, and the extension direction of the first rails 2 is as follows: Figure 1 The direction of the X-axis is shown in the diagram. The first drive unit 5 adopts the structure of the previous trailer drive unit.

[0046] The second track 3 is fixedly installed at the bottom of the trailer main frame 1 and is arranged parallel to the trailer main frame 1, that is, the second track 3 extends along the Y-axis direction; the second track 3 includes a base plate, a pad plate and a track body, and the track body is connected to the trailer main frame 1 through the base plate and the pad plate; the sub-frame assembly 4 is installed on the second track 3 and moves along the second track 3 through the second drive device 6, that is, moves along the Y-axis direction.

[0047] Test frame 7 is mounted on subframe assembly 4 and is located in a position to move vertically via third drive device 8; test frame 7 is provided with slewing mount 9; test slewing arm 20 is rotatably connected to slewing mount 9 and its slewing angle is adjusted via fourth drive device 10.

[0048] All of the above drive devices are equipped with brakes, guide rail clamps, or locking mechanisms to lock the position after the device has moved into place. The brakes, guide rail clamps, or locking mechanisms are existing finished products that can be purchased and used directly.

[0049] With the above structural setup, the main trailer frame 1 can move on the first track 2 via the first drive device 5, and the main trailer frame 1 is perpendicular to the first track 2. The subframe assembly 4 moves along the second track 3 via the second drive device 6, and the test frame 7 on the subframe assembly 4 can move vertically. The test rotating arm 20 on the test frame 7 is connected to the ship. Thus, in use, the second drive device 6 moves the subframe assembly 4 to the dock at a specified speed. Then, the third drive device 8 lowers the subframe assembly 4 to a test height above the ship model in the dock. Then, the test rotating arm 20 is connected to the ship model under test. Finally, the first drive device 5 controls the main trailer frame 1 to move to the test area in the pool at a specified speed along the X-axis and the first track 2, while the second drive device 6 controls the subframe assembly 4 to move along the Y-axis and the second track 3 at a specified speed. The test rotating arm 20 is controlled to rotate the ship model at a specified time, thereby achieving comprehensive verification and improving the verification effect.

[0050] In some preferred embodiments, the trailer system further includes a control device that is signal-connected to the first drive unit 5, the second drive unit 6, and the third drive unit 8 to control the movement distance of the trailer main frame 1 and the sub-frame assembly 4, as well as the lifting height of the test frame 7 and the rotation angle of the test slewing arm 20.

[0051] It also includes an optical tracking component 11 mounted on the subframe body 400. The optical tracking component 11 includes a bracket and an optical tracker, which is used to monitor and measure the ship.

[0052] The trailer system's status when following the self-propelled boat model: The control device controls the first drive unit 5 to drive the trailer main frame 1 along the second track 3 at a specified speed to the water tank dock. The third drive unit 8 drives the test frame 7 to descend along the rolling guide rail to the test height above the dock, and the test frame 7 is locked by the locking mechanism. The control device controls the trailer main frame 1 to move to the water tank test area at a specified speed along the X-axis, while simultaneously controlling the sub-frame assembly 4 to move along the Y-axis at a specified speed. During this process, the optical instruments on the optical tracking assembly 11 track, monitor, and measure the self-propelled boat model.

[0053] refer to Figures 3-5 In some preferred embodiments, the structure of the subframe assembly 4 is described below:

[0054] The subframe assembly 4 includes: a subframe body 400, which has an internal accommodating space and a first ladder railing 401 on the outside; a third drive device 8 is also connected to the outside of the subframe body 400; a first mounting bracket 402, which is fixed to the top of the subframe body 400 and hung on the second track 3, and the first mounting bracket 402 is provided with guide pulleys that abut against both sides of the second track 3, so that the first mounting bracket 402 is stably connected to the second track 3 while being movable; a work platform 403, which is set in the accommodating space and moves vertically by a fifth drive device, and a control room 404 is provided on the work platform 403.

[0055] Among them, reference Figure 6 and Figure 7 The test frame 7 includes an H-shaped stretcher 700 and a triangular connecting frame 701. The triangular connecting frame 701 is connected to both ends of the H-shaped stretcher 700. The third drive unit 8 is vertically arranged and connected to the triangular connecting frame 701. In use, the subframe body 400 provides the mounting points for the work platform 403 and the third drive unit 8. The test frame 7 has a simple structure with guaranteed structural strength, and also provides a mounting position for the slewing mounting component 9.

[0056] refer to Figure 8 and Figure 9 The rotating mounting component 9 includes a connecting block and a crossbar. The crossbar is mounted on the top of the connecting block and is bolted to the test frame 7. A rotating shaft is rotatably connected to the connecting block and is connected to the test rotating arm 20. The rotating shaft is equipped with a gear that is connected to the fourth drive device 10 for transmission. The test rotating arm 20 can rotate 360 ​​degrees. It is a directly purchased product, and its structure is shown in the figure.

[0057] In use, the fourth drive device 10 drives the rotating shaft to rotate the test rotating arm 20, and the fourth drive device 10 is also equipped with a locking structure for locking and unlocking the rotating shaft.

[0058] It also includes an optical tracking component 11 mounted on the subframe body 400. The optical tracking component 11 includes a bracket and an optical tracker, which is used to monitor and measure the ship.

[0059] refer to Figure 10 and Figure 11 To enable this trailer system to have a viewing platform that can move up and down while moving along with the subframe assembly 4, the following settings were implemented:

[0060] A second mounting bracket 12 is movably connected to the second track 3. A visitor vehicle frame 13 is located at the bottom of the second mounting bracket 12, and a second escalator railing 15 is located on the outside of the visitor vehicle frame 13. A visitor platform 14 is connected to the visitor vehicle frame 13 via a sixth drive device, allowing the visitor platform 14 to move vertically. The visitor vehicle frame 13 and the sub-frame assembly 4 are spaced apart and connected by a connecting rod 16. A pin is provided in the connecting rod 16 for limiting the top position of the visitor vehicle frame 13 and the sub-frame assembly 4. Both mounting brackets are equipped with four wheels for movement; the wheels of the first mounting bracket 402 are driving wheels, and the wheels of the second mounting bracket 12 are driven wheels.

[0061] Due to the connection rod 16, the visitor vehicle frame 13 and the sub-frame body 400 are connected as a whole. In addition, the second mounting bracket 12 slides on the second track 3, so that the sub-frame assembly 4 moves along with the visitor vehicle frame 13.

[0062] It also includes an optical tracking component 11 mounted on the subframe body 400. The optical tracking component 11 includes a bracket and an optical tracker, which is used to monitor and measure the ship.

[0063] refer to Figure 12 and Figure 13 Since the visitor vehicle frame 13 and the subframe body 400 are simply connected into a whole by the connecting rod 16, the subframe assembly 4 and the visitor vehicle frame 13 have many structures, making them prone to shaking during the test. To strengthen the connection between the two, the following settings were implemented:

[0064] The system also includes a circular frame 18, with connecting bases 17 on the visitor vehicle frame 13 and the subframe assembly 4; the circular frame 18 is mounted on the connecting bases 17. This arrangement uses the circular frame 18 to further reinforce the connection between the visitor vehicle frame 13 and the subframe assembly 4. This prevents changes in the distance between the visitor vehicle frame 13 and the subframe assembly 4 during movement, avoiding the risk of collision. Because the circular frame 18 needs to accommodate observation and lighting equipment and temporary stands for maintenance work, it requires a certain degree of rigidity; therefore, tensioning fasteners 19 are added.

[0065] The circular frame 18 is also equipped with tensioning fasteners 19 that connect to the visitor vehicle frame 13 and the sub-frame assembly 4. The tensioning fasteners 19 include tension ropes and tension bolts, with the tension ropes connected to the tension bolts at both ends. Mounting holes are provided on the circular frame 18, the visitor vehicle frame 13, and the sub-frame assembly 4. The tensioning fasteners 19 can be referenced from tensioning structures commonly used in the bridge construction field.

[0066] Furthermore, the circular frame 18 can be a single full circle structure as described above, or it can be composed of two semicircles. When the sub-frame body 400 is separated from the viewing platform 14, the circular frame 18 can be detached from the center line. That is, the semicircular frame is installed on the sub-frame body 400 for operation, and the other semicircular frame is installed on the viewing platform 14 and rests on the second track 3.

[0067] Thus, through the above settings, the trailer system can be fully verified during the water tank test, and visitors can observe it. In addition, during operation, the viewing platform 14 and the subframe assembly 4 are stably connected to avoid collisions and enhance safety.

[0068] The principle of this application:

[0069] Since the main trailer frame 1 can move on the first track 2 via the first drive device 5, and the main trailer frame 1 is perpendicular to the first track 2; the sub-frame assembly 4 moves along the second track 3 via the second drive device 6, and the test frame 7 on the sub-frame assembly 4 can move vertically, with the test rotating arm 20 on the test frame 7 connected to the ship, in use, the second drive device 6 moves the sub-frame assembly 4 to the dock at a specified speed; then the third drive device 8 lowers the sub-frame assembly 4 to a test height above the ship model in the dock. Then the test rotating arm 20 is connected to the ship model to be tested, and finally the first drive device 5 controls the main trailer frame 1 to move to the test area in the pool at a specified speed along the X-axis and the first track 2, while the second drive device 6 controls the sub-frame assembly 4 to move along the Y-axis and the second track 3 at a specified speed, controlling the test rotating arm 20 to rotate the ship model at a specified time, thereby achieving comprehensive verification and improving the verification effect.
