Description

Technical Field

[0001] This invention relates to the field of deep-sea engineering technology, and specifically to a trailer installation method for a deep-water test pool. Background Technology

[0002] Currently, combined wind and wave deep-water laboratories are widely used to simulate the effects of complex marine environmental loads such as sea winds and waves on structures. These laboratories typically generate wind loads through a wind-generating system, which are then rectified to create a stable wind field that acts on the test model. Simultaneously, deep-water test pools are used to simulate wave loads. To meet the needs of multidisciplinary testing, the laboratories are usually equipped with mobile trailer systems to carry work platforms or test equipment for testing under various conditions.

[0003] Traditional trailer systems typically employ an integrated structure, with the main vehicle and auxiliary vehicle often consisting of enclosed or semi-enclosed frames, and their operation control devices usually integrated within the auxiliary vehicle. However, in the combined wind and wave laboratory of a large-scale, vertically oriented 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 enclosed or semi-enclosed structure of traditional trailers may disturb the flow field inside the wind tunnel, affecting the test accuracy;

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

[0006] 3. Installation time conflict: The trailer needs to be transported to the designated location before the completion of the wind tunnel structure above the water tank, but due to the impact of the construction progress, it may not be possible to complete the installation in one go;

[0007] 4. Ease of operation: The control devices of traditional trailers are usually placed inside the sub-vehicle frame, which is not conducive to the test personnel's quick adjustment and monitoring. Summary of the Invention

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

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

[0010] S1. Use the center line of the on-site water tank as the reference line for the installation of the XY trailer, and carry out the fabrication and installation of the foundation frame;

[0011] S2. Use a crane to lift and install the segmented main car body structure into place, ensuring that the center line of the wheel set coincides with the center line of the main car track; adjust the position of the car body so that the diagonal deviation is controlled within the threshold range, and after confirming that there are no errors, drive in the positioning pin to fix it.

[0012] S3. Use a crane to lift the motor and reducer to the designated position through the mounting port, and connect the wheel set, reducer and motor through a 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 position of the vehicle body through the guide wheels. Complete the assembly of the upper truss.

[0014] S5. Based on the measured height between the main vehicle track and the bottom of the XY trailer beam, prepare the first mounting base plate; weld and fix the first base plate to the bottom of the XY trailer beam on site, install the hydraulic brake, and adjust its position so that the gap between the brake pads and both sides of the main vehicle track is uniform.

[0015] S6. Based on the actual measured height of the main vehicle track, construct and weld a transition plate for the guide device installation to ensure that: ① the center line of the side of the main vehicle track 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. Based on the actual measured height of the main vehicle track, install and weld the transition plate for the cleaning device, and adjust the cleaning brush to make it fit tightly against the surface of the main vehicle track.

[0017] S8. Based on the measured height between the main vehicle track and the bottom of the XY trailer beam, prepare a second mounting base plate; weld and fix 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 and fix the 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 electrical control cabinet is installed on a base frame that has been treated with anti-corrosion. Cables are laid in a single layer along the cable tray or cable trough. At bends and branches, they are stacked and arranged neatly.

[0020] S11. The sliding contact line is suspended on the mounting bracket through an insulator. The carbon brush slider of the XY trailer current collector is kept in close contact with the lower surface of the sliding contact line. Adjust the clamping force of the current collector to ensure the continuity of power supply during the entire operation of the XY trailer.

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

[0022] In a preferred embodiment 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] In a preferred embodiment of the present invention, in step S6, 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 by adjusting the eccentric wheel shaft.

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

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

[0026] As a preferred embodiment of the present invention, in step S9, when installing the hydraulic buffer on the buffer support, it is ensured that the axis of its buffer head is perpendicular to the force-bearing surface of the trailer buffer block, and the perpendicularity is ≤0.5mm / m.

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

[0030] This invention, by employing the above technical solutions, achieves the following technical effects: The invention effectively solves the installation challenges posed by the enclosed space of the laboratory through a step-by-step assembly scheme. In specific implementation, a main vehicle structure welded from circular steel pipes ensures overall rigidity, while the auxiliary vehicle adopts a lightweight open truss design. The combination of these two features reduces the overall drag coefficient by more than 40%. Regarding installation management, an innovative "pre-transport + opportunistic installation" model is adopted. All components are transported to a designated temporary storage area in the laboratory in advance. After the upper wind tunnel main body is installed and accepted, precise on-site assembly is carried out based on measured space data. This scheme not only avoids cross-interference with the installation of wind tunnel equipment but also improves installation efficiency by 30%. Attached Figure Description
