[0036] The following is combined with Figure 1-6 The present application is further described in detail with specific embodiments:

[0037] In order to achieve the high requirements of wind tunnel body component installation positioning accuracy: after the components are installed, the coaxiality of the center line relative to the center axis of the wind tunnel body should not be greater than The step difference between the two components is no more than 0.02 mm, and the components only have X-direction freedom after they are in place. The embodiment of the present application discloses a wind tunnel body component suspension system and method.

[0038] Taking the nozzle section as an example to explain the wind tunnel body equipment suspension system, refer to Figure 1 and Figure 2 A wind tunnel body component suspension system includes a gantry 104, a suspension hoop connecting platform 102, an adjustable suspension rod 101, and a sliding seat 103; the suspension hoop connecting platform 102 suspends the wind tunnel body component on the gantry 104 through the adjustable suspension rod 101 and the sliding seat 103.

[0039] Reference Figure 1 and Figure 2, a set of gantry 104 is arranged at each end of the wind tunnel body component. In this embodiment, two gantry 104 are arranged, and each set of gantry 104 is welded with steel. The bottom of the gantry 104 is fixedly installed on the wind tunnel foundation. In order to ensure the bearing capacity of the gantry 104, the welding structure of the gantry 104 needs to ensure sufficient strength and rigidity; two H-shaped rails 402 are installed between the two sets of gantry 104, and the two H-shaped rails 402 are arranged at the two ends of the inner side of the gantry 104, and the rails are composed of processed H-shaped steel. Specifically, the inner side of the two ends of the gantry 104 is fixedly connected with a connecting inclined plate 403, and the upper wing plate of the H-shaped steel is connected to the connecting inclined plate 403 by bolts, and the obtained H-shaped steel at 30° with the horizontal plane is used as the H-shaped rail 402.

[0040] Reference Figure 5 and Figure 6 The sliding seat 103 is slidably connected to the H-shaped track 402 along the length direction of the H-shaped track 402. The sliding seat 103 includes a bearing slider 501, a follower slider 503, and a connecting plate 505. The bearing slider 501 is located on the side of the web of the H-shaped steel facing the center of the gantry 104. The side of the bearing slider 501 facing the web of the H-shaped steel and the side of the bearing slider 501 facing the lower wing of the H-shaped steel are perpendicular to each other. The follower slider 503 is located on the side of the web of the H-shaped steel away from the center of the gantry 104. The connecting plate 505 is located below the lower wing of the H-shaped steel and is connected between the bearing slider 501 and the follower slider 503. The side of the connecting plate 505 away from the bearing slider 501 and the follower slider 503 is connected to a connecting ear seat 504 connected to the earring at the end of the coarse thread pull rod 302. A pin is set on the connecting ear seat 504 to connect with the adjustable suspension pull rod 101. The side surfaces of the bearing slider 501 abutting against the web and lower wing of the H-shaped steel are connected with rolling guide blocks 502, and the side surfaces of the following slider 503 abutting against the lower wing of the H-shaped steel are connected with rolling guide blocks 502. This structural arrangement enables the bearing slider 501 to have a good bearing capacity and a guiding function. The arrangement of the bearing slider 501 and the following slider 503 ensures that the wind tunnel component moves more smoothly and stably in the X direction.

[0041] Reference Figure 3Each suspension clamp connection platform 102 is connected to a split clamp, which is connected to the outside of the wind tunnel body component. The split clamp is welded by pre-set arc steel plate and rib plate, and the whole is processed by heat treatment after welding. A split clamp is connected to each end of the wind tunnel body component, that is, a suspension clamp connection platform 102 is connected to each end of the wind tunnel body component. The split clamp includes a clamp divided into upper and lower halves, and a clamp connecting rod 202 is connected between the two halves of the clamp. Both ends of the clamp connecting rod 202 are threaded, and nuts for locking the two halves of the clamp are arranged on the clamp connecting rod 202. Each split clamp is locked with 4 clamp connecting rods 202 and nuts on the clamp connecting rod 202, so that the split clamp clamps the wind tunnel body component, ensuring that the clamp and the body component are in good and stable contact. The top end of the clamp link 202 is connected to the suspension clamp connection platform 102, and both ends of each suspension clamp connection platform 102 are connected to the sliding seat 103 through an adjustable suspension rod 101, that is, each suspension clamp platform needs to be installed with two sets of adjustable suspension rods, and the two sets of adjustable suspension rods are arranged at 120° with the overall axis of the wind tunnel body as the center.

[0042] Reference Figure 3 and Figure 4 The suspension hoop connecting platform 102 includes a connecting platform 201 and ear seats 203 connected to both ends of the connecting platform 201. The top ends of the four hoop connecting rods 202 are connected to the connecting platform 201. The connecting platform 201 includes an upper plate 61, a lower plate 62, a side plate 63, a fixed plate 64, and a reinforcing plate 65. The upper plate 61 and the lower plate 62 are parallel to each other. The side plate 63 is connected to the ends of the upper plate 61 and the lower plate 62. The ear seats 203 are fixedly connected to the outer surface of the side plate 63. The ear seats 203 are tilted. With the central axis of the wind tunnel body as the reference, the angle between the two ear seats 203 at both ends of the connecting platform 201 is 120 degrees. The fixed plate 64 is perpendicular to the upper plate 61 and connected to the middle of the upper plate 61 and the lower plate 62. The reinforcing plate 65 is tilted and connected between the upper plate 61 and the lower plate 62. The upper surface of the connecting platform 201 is finely processed to ensure sufficient flatness and roughness. The upper surface of the connecting platform 201 is adjusted to be parallel to the overall central axis of the wind tunnel body and have the same distance to the central axis of the wind tunnel body. The upper surface of the connecting platform 201 serves as a measurement reference for installation and adjustment.

[0043] The adjustable suspension rod 101 includes a pull ring 303, a coarse thread pull rod 302, and a fine thread pull rod 304. The coarse thread pull rod 302 and the fine thread pull rod 304 are respectively connected to the two ends of the pull ring 303. The coarse thread pull rod 302 and the fine thread pull rod 304 are threadedly connected with nuts at both sides of the pull ring 303. The other ends of the fine thread pull rod 304 and the ball hinge earring 301 are both ball hinge earrings 301. The ball hinge earring 301 of the fine thread pull rod 304 is installed on the ear seat 203 of the connecting platform 201 through a pin, and the ball hinge earring 301 of the coarse thread pull rod 302 is installed on the ear seat 203 of the sliding seat 103 through a pin. By adjusting the length of the coarse thread pull rod 302 and the fine thread pull rod 304, the installation position of the wind tunnel body component clamped on the suspension clamp connecting platform 102 is adjusted to meet the installation technical requirements between the wind tunnel body components.

[0044] The adjustable suspension rod system is a rigid structure, which provides a tension force and the gravity of the wind tunnel body components at 120° to each other. Assume that the central axis direction of the wind tunnel body component is the X direction, the vertical direction is the Y direction, the direction perpendicular to the X and Y directions is the Z direction, the YX direction is the pitch α, the XZ direction is the yaw β, and the rotation around the X direction is the roll γ. Through static analysis, the wind tunnel body components are in a state of force balance in the Y and Z directions, and have no degrees of freedom in the Y and Z directions. After the two sets of suspension clamp connection platforms 102 and the four sets of adjustable suspension rod systems arranged on each body component are combined and locked, the body components have no pitch α, yaw β, and roll γ degrees of freedom. The body components have only X-direction degrees of freedom.

[0045] This embodiment also discloses a method for suspending a wind tunnel body component, comprising the following steps:

[0046] The anchor bolts for the gantry 104 are set on the foundation of the wind tunnel body component, and the gantry 104 processed as a whole after welding is hoisted to the anchor bolts reserved on the foundation of the tunnel body for installation. The horizontal plane passing through the axis of the wind tunnel body is the horizontal symmetry plane of the wind tunnel body, and the vertical plane passing through the axis of the wind tunnel body is the vertical symmetry plane of the wind tunnel body. With the horizontal symmetry plane and the vertical symmetry plane of the wind tunnel body as the reference, the installation positions of the two sets of gantries 104 are adjusted. After adjustment, the parallelism error between the measurement reference plane of the gantry 104 and the horizontal symmetry plane is 0.1mm, and the verticality error with the vertical reference plane is 0.1mm; after the gantry 104 is installed in place, the H-shaped track 402 is installed on the gantry 104 by bolts. Before installing the two tracks, the sliding surface of the track should be cleaned and treated on the ground. After installation, ensure that the two track surfaces are 30°±3° with the horizontal symmetry plane of the wind tunnel body.

[0047] Pre-install the rolling guide block 502 into the mounting surface of the bearing slider 501 and the follower slider 503. After installation, ensure that the bearing slider 501 and the follower slider 503 can slide smoothly on the reference platform without sticking; install the bearing slider 501 and the follower slider 503 on the track according to the structure of the sliding seat 103, and fix the bearing slider 501 and the follower slider 503 with the connecting plate 505. After assembly, the sliding seat 103 must be tested on the track to ensure smooth sliding and ensure that only the rolling guide block 502 installed on the sliding seat 103 is in contact with the track surface, and the rest of the parts are not in contact; two pairs of sliding seats 103 are installed for each suspension clamp system.

[0048] The suspension clamp connection platform 102 and the wind tunnel body component are installed as a whole on the reference platform, and the reference platform is used as the measurement reference. The connection platform 201 is adjusted to be parallel to the center line of the component, and at the same time, it is ensured that the distances from the upper surfaces of the two connection platforms 201 to the center line are equal. After the adjustment is completed, all components are locked together, and lines are engraved on the upper surface of the connection platform 201, one line is parallel to the axis of the wind tunnel body component, and the other is perpendicular to the axis of the wind tunnel body component, to provide a measurement reference for the next step of installation; thereby, the center axis of the wind tunnel body component is materialized on the connection platform 201 of the suspension clamp system.

[0049] The structural component that integrates the wind tunnel body component and the suspension hoop platform is temporarily placed on a movable ground auxiliary installation support, transported to the vicinity of the component installation position by the auxiliary installation support, and the component position is preliminarily adjusted using the auxiliary installation bracket.

[0050] Previously, the sliding seat 103 on the gantry 104 track was installed in place, and the position of the ear seat 203 on the sliding seat 103 has been determined. According to the theoretical position of the wind tunnel body components, the distance between the pin hole of the ear seat 203 on the connecting platform 201 and the pin hole of the ear seat 203 on the connecting plate 505 of the sliding seat 103 can be obtained through preliminary geometric calculation; at this time, the length of the suspension rod system is preliminarily adjusted to the calculated value between the two ear seats 203 according to the calculation results, and then the earrings at both ends of the suspension rod system are installed on the ear seat 203 through the pin. The actual length of the suspension rod system can be achieved by adjusting the length of the fine-thread and coarse-thread threaded rods 302.

[0051] At this time, the wind tunnel body components are preliminarily installed in place through the suspension hoop platform, the adjustable suspension rod system, the sliding seat 103 and the gantry 104, and the auxiliary installation bracket is separated from the wind tunnel body components, which only serves as a safety protection.

[0052] Adjust the laser theodolite reference to the horizontal and vertical symmetry reference planes of the wind tunnel body. The horizontal and vertical symmetry planes of the wind tunnel body have been solidified in the laboratory workshop. Record the theodolite reading at this time, and place the height gauge based on the existing engraved lines on the connecting platform 201. Because the distance and parallelism from the connecting platform 201 to the center axis of the tunnel body component have been adjusted and fixed on the reference platform, the fixed reading of the height gauge plus the reading from the connecting platform 201 to the center of the component is the height gauge reading value observed by the theodolite. Adjust the lengths of the coarse threaded rod 302 and the fine threaded rod 304 of the adjustable suspension rod system respectively to adjust the position of the component, and adjust the center line of the part to be consistent with the center axis of the wind tunnel body.

[0053] A laser theodolite is used to measure the position and reading of the height gauge placed on the two hanging hoop platforms respectively, so as to adjust the wind tunnel body components in the Y direction, Z direction, yaw β, pitch α and roll γ directions relative to the central axis of the wind tunnel body, so as to achieve the coaxiality requirement between the central axis of the component and the central axis of the wind tunnel body.

[0054] After the position of the first wind tunnel body component meets the requirements, all adjustable parts of the suspension system are locked. At this time, this wind tunnel body component can be used as the position reference for the next wind tunnel body component connected to it. The above measurement and adjustment method is repeated to ensure the position accuracy of the wind tunnel body component itself and the step difference between two adjacent wind tunnel body components.

[0055] The application of wind tunnel body equipment suspension system can improve the installation accuracy and operation stability of the body components.

[0056] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
