Description

Technical Field

[0001] The present invention relates to the technical field of deep sea engineering, and in particular to a method for installing a trailer for a deep water test pool. Background Art

[0002] Currently, wind-wave combined deepwater laboratories are widely used to simulate the effects of complex marine environmental loads, such as wind and waves, on structures. These laboratories typically generate wind loads through wind-generating systems, which are then rectified to form a stable wind field that acts on the test model. Simultaneously, deepwater test tanks are used to simulate wave loads. To meet the needs of multidisciplinary testing, these laboratories are often equipped with mobile trailer systems to carry work platforms or test equipment, enabling testing under various operating conditions.

[0003] Traditional trailer systems typically use an integrated structure, with the main and auxiliary vehicles often being closed or semi-closed frames, and their operation control devices usually integrated into the auxiliary vehicle. However, in the wind-wave joint laboratory of a large-scale up-and-down circulation wind tunnel, due to the closed vertical structure of the wind tunnel and the large span of the water tank, the installation of the trailer faces the following technical challenges:

[0004] 1. Wind field interference: The closed or semi-closed structure of traditional trailers may disturb the flow field in the wind tunnel, affecting the test accuracy;

[0005] 2. Space limitation: After the upper wind tunnel is installed, the internal space is limited and it is impossible to carry out the overall trailer lifting;

[0006] 3. Installation sequence conflict: The trailer needs to be transported to the designated location before the wind tunnel structure above the pool is completed. However, due to the construction progress, it may not be possible to complete the installation in one go.

[0007] 4. Operational convenience: The control devices of traditional trailers are usually placed in the auxiliary vehicle frame, which is not conducive to rapid adjustment and monitoring by test personnel. Summary of the Invention

[0008] The purpose of the present invention is to provide a trailer installation method for a deep water test tank, which can effectively reduce the resistance to the wind field, improve the operational convenience, and avoid interfering with the installation process of other equipment.

[0009] To achieve the above objectives, the technical solution of the present application is: a trailer installation method for a deep water test tank, comprising:

[0010] S1. Use the center line of the on-site pool as the reference line for the XY trailer installation to manufacture and install the base frame;

[0011] S2. Use a crane to hoist the segmented main vehicle body structure into place, ensuring that the centerline of the wheel assembly coincides with the centerline of the main vehicle track. Adjust the vehicle body position to keep the diagonal deviation within the threshold range. After confirming that it is correct, drive the locating pins to secure it.

[0012] S3. Use a crane to hoist the motor and reducer through the installation port to the designated location, and connect the wheel assembly, reducer and motor through the coupling;

[0013] S4. Install the auxiliary vehicle track on the upper part of the main vehicle and complete the adjustment. Assemble the auxiliary vehicle as a whole on the ground; hoist the auxiliary vehicle onto the auxiliary vehicle track and adjust the vehicle body position using the guide wheels; and complete the assembly of the upper truss.

[0014] S5. Prepare a first mounting base plate based on the measured height between the main vehicle track and the bottom of the XY trailer beam; weld the first base plate to the bottom of the XY trailer beam on site, install the hydraulic brake, and adjust its position to ensure an even gap between the brake pads and both sides of the main vehicle track;

[0015] S6. According to the measured height of the main vehicle track, prepare and weld the fixed guide device to install the transition plate, ensuring that: ① the center line of the main vehicle track side coincides with the center line of the guide wheel width; ② the center line of the guide device coincides with the center line of the main vehicle track;

[0016] S7. Prepare and weld the transition plate for the cleaning device according to the measured height of the main vehicle track, and adjust the cleaning brush to make it fit closely with the main vehicle track surface;

[0017] S8. Prepare a second mounting base plate based on the measured height between the main vehicle track and the bottom of the XY trailer beam; weld the second base plate to the bottom of the XY trailer beam on-site, install the speed measuring device, and adjust the center line of the speed measuring device to coincide with the center line of the main vehicle track;

[0018] S9. Weld the fixed buffer support according to the actual measured dimensions on site, and simultaneously weld the front and rear buffer blocks of the XY trailer;

[0019] S10. The electric control cabinet shall be installed on a foundation frame treated with anti-corrosion. The cables shall be laid in a single layer along the bridge or cable duct, and shall be stacked and arranged neatly at bends and branches.

[0020] S11. The busbar is suspended on the mounting bracket through an insulator. The carbon brush slider of the XY trailer collector maintains close contact with the lower surface of the busbar. The pressing force of the collector is adjusted to ensure power supply continuity during the entire operation of the XY trailer.

[0021] As a preferred solution of the present invention, step S3 further includes: adjusting the pad to ensure that the axes of the reducer, the motor and the wheel axle are collinear and aligned in height direction.

[0022] As a preferred solution of the present invention, in step S4, the center line of the auxiliary vehicle is kept parallel to the center line of the auxiliary vehicle track.

[0023] As a preferred solution of the present invention, in step S6, the eccentric wheel shaft is adjusted so that the gap between the guide wheel and the main vehicle track is 0.3mm±0.05mm, and the gap between the guide wheel and the auxiliary vehicle track is 1-2mm.

[0024] As a preferred solution of the present invention, during installation in step S7, the center line of the cleaning device is offset by 30 mm ± 2 mm relative to the center line of the main vehicle track to ensure that the cleaning device can rotate autonomously to complete the track cleaning operation when the XY trailer is running.

[0025] As a preferred solution of the present invention, in step S8, the speed measuring wheel is adjusted so that the positive pressure of the contact with the main vehicle track is maintained in the range of 3-4 kg.

[0026] As a preferred solution of the present invention, when installing the hydraulic buffer on the buffer support in step S9, ensure that the axis of the buffer head is perpendicular to the load-bearing surface of the trailer buffer block, and the verticality is ≤0.5mm / m.

[0027] As a preferred solution of the present invention, in step S10, the control signal shielded cable is double-ended grounded, and the detection signal and transmitter wiring shielded cable is single-ended grounded on the strong noise source side.

[0028] As a preferred solution of the present invention, the main vehicle adopts a circular steel tube frame structure, and the auxiliary vehicle is designed as an open truss form.

[0029] As a preferred solution of the present invention, each structural component is first transported to a designated storage area in the laboratory before the upper wind tunnel is installed.

[0030] Due to the adoption of the above technical solutions, the present invention can achieve the following technical effects: The present invention effectively solves the installation difficulties caused by the closed laboratory space through a step-by-step assembly solution. During the specific implementation process, the main vehicle structure is welded with circular steel pipes to ensure overall rigidity, while the auxiliary vehicle adopts a lightweight open truss design. The combination of the two reduces the overall drag coefficient by more than 40%. In terms of installation management, the innovative "pre-transportation + installation at the right time" model is adopted. All components are transported to the designated temporary storage area of ​​the laboratory in advance. After the installation and acceptance of the upper wind tunnel body is completed, precise on-site assembly is implemented according to the measured space data. This solution not only avoids cross-interference with the installation of wind tunnel equipment, but also improves installation efficiency by 30%. BRIEF DESCRIPTION OF THE DRAWINGS
