Description

Technical Field

[0001] The present invention relates to the technical field of wind tunnel experiments, and in particular to a steel structure wind tunnel body splicing section support structure and an installation method thereof. Background Art

[0002] A wind tunnel experiment refers to a device that studies the interaction between gas flow and models in a hollow, hole-shaped device. It is mostly used to study the interaction between aircraft and airflow, making it an important device for existing aircraft experiments. However, due to the increased volume and weight of some existing large wind tunnels, relying solely on the support of the bottom support column, it is easy for the wind tunnel body to shake due to the internal airflow circulation, and it is impossible to stably support the wind tunnel body as a whole. It is difficult to ensure the parallel accuracy between the wind tunnel bodies during segmented installation, which increases the difficulty of installing some large wind tunnel bodies. Summary of the Invention

[0003] The purpose of the present invention is to provide a steel structure wind tunnel splicing section support structure and its installation method, so as to solve the problem that when installing the wind tunnel body, the volume and weight of some large wind tunnel bodies increase, resulting in the support being unstable and prone to shaking when supported only by the bottom part, and the parallel accuracy of the wind tunnel body cannot be guaranteed.

[0004] The embodiments of the present invention are achieved through the following technical solutions:

[0005] The present invention provides a support structure for a spliced ​​section of a steel structure wind tunnel body and an installation method thereof, comprising a wind tunnel body, wherein the side walls of the wind tunnel body are provided with reinforcing ribs, the reinforcing ribs are arranged in groups of two, support columns are provided at the bottom of the reinforcing ribs, a connecting plate is provided at the bottom of the support columns, an adjusting column is provided in the middle of the connecting plate, a mosaic column is connected to the middle of the adjusting column, a jack is provided in the middle of the adjusting column and the mosaic column, and a base is provided at the bottom of the connecting plate.

[0006] The support of the reinforcing ribs and support columns mentioned above can more effectively and stably support the wind tunnel body, so that it can stably support some large and heavy wind tunnel bodies. At the same time, the height of the wind tunnel body support can be leveled by adjusting the telescopic adjustment of the adjustment column to keep the wind tunnel body in its parallel state.

[0007] Preferably, the adjusting column also includes a limiting shaft and an engaging groove, the limiting shaft is a circular shaft arranged between the side walls of the adjusting column, and the protruding part of the limiting shaft is on the inner wall of the adjusting column, the engaging groove is a circular shaft groove connected to the limiting shaft, and a thread groove is provided on the inner wall of the engaging groove opening.

[0008] Preferably, the chimeric column is also provided with a fitting groove and a limiting groove. The fitting groove is an arc-shaped groove on the side wall of the chimeric column, and the fitting groove cooperates with the inner wall portion of the regulating column protruding from the limiting shaft. The limiting groove is a groove with an inwardly inclined arc extending on one side of the fitting groove surface.

[0009] Preferably, the limiting shaft is also provided with a rotating disk, a rotating shaft, a rotating ring groove, a limiting disk and a deflection shaft. The rotating disk is several circular disks connected in the limiting shaft, the rotating shaft is a circular shaft connected to the limiting shaft at the top of the rotating disk, the rotating ring groove is a circular groove at the bottom of the rotating disk, the limiting disk is several circular disks with smaller diameters connected in the middle of the limiting shaft, and the top of the limiting disk is fitted with the rotating disk, the deflection shaft is a circular shaft connected through the limiting disk, and the protruding limiting disk part at the top of the deflection shaft cooperates with the rotating ring groove.

[0010] Through the cooperation of the rotating disk and the limiting disk in the above content, when the adjusting column is separated, contracted and parallel-leveled, the thread in the engaging groove drives the rotating disk in the limiting shaft to rotate, and the rotation of the rotating disk drives the limiting disk to rotate eccentrically, so that the limiting block is engaged in the limiting groove for limitation, so that the adjusting column can be more stable after extension and leveling, and will not be affected by the experimental vibration of the wind tunnel body.

[0011] Preferably, the side wall of the rotating disk is threadably matched with the opening of the inner wall of the engaging groove.

[0012] Preferably, the limiting disk is further provided with a limiting block, which is an arc convex block extending obliquely from one side of the limiting disk, and the limiting block cooperates with the limiting groove.

[0013] Preferably, the top side wall of the deflection shaft is threadedly engaged with the inner wall of the rotating ring groove, and the deflection shaft is arranged near one side of the limiting plate.

[0014] Preferably, a method for splicing and installing a steel structure wind tunnel body comprises the following steps:

[0015] The first step is to prefabricate the connecting reinforcement ribs on the wind tunnel body, and then set fixed installation support columns at the bottom of the reinforcement ribs. After completion, the wind tunnel body is hoisted;

[0016] The second step is to install the base at the location where the wind tunnel body is to be installed. The base is then connected to the concrete through anchor bolts. A connecting plate is installed on the top of the base, and an adjustment column is set in the connecting plate to complete the installation of the lower support system.

[0017] The third step is to adjust the height of the wind tunnel body by changing the height of the connection between the connecting plate and the wind tunnel body through adjusting the height of the adjusting column after the base, connecting plate and adjusting column are installed to form the lower support system, thereby adjusting the support height of the wind tunnel body and leveling the wind tunnel body.

[0018] In the fourth step, after the height of the adjustment column is adjusted, the support column set on the reinforcement rib on the wind tunnel body will be connected to the reserved bolt hole on the connecting plate to complete the leveling and installation of the wind tunnel body. At the same time, the setting of the reinforcement rib can increase the downward force transmission area, reduce stress, and avoid stress concentration, so that the reinforcement rib can evenly transmit the uniform surface load downward, so that when installing some wind tunnel bodies of different sizes and weights, they can also be stably installed and bear the load;

[0019] In the third step, when the height of the adjusting column is adjusted, the limiting shaft is rotated by the extension of the height of the adjusting column, so that the limiting plate in the limiting shaft will loosen and rotate eccentrically, thereby limiting the connection with the interlocking column in the adjusting column to increase the tensile strength of the adjusting column after separation and avoid deviation and tilt due to vibration.

[0020] The technical solutions of the embodiments of the present invention have at least the following advantages and beneficial effects:

[0021] 1. When the reinforcing ribs and support columns provided in the device are used to support some large and heavy wind tunnel bodies, the surrounding support of the reinforcing ribs can form an integrated support with the wind tunnel body, evenly supporting its weight, and stably supporting the large and heavy wind tunnel body on one side.

[0022] 2. The device is also provided with an adjustment column, which can be raised and lowered during installation by extending the internal jack, so that the adjustment column can facilitate parallel leveling of the wind tunnel body, making it more accurate during installation.

[0023] 3. The device is also equipped with a limiting shaft. When the adjusting column separates and the height is adjusted along the interlocking column to level the wind tunnel body, the limiting shaft rotates and interlocks with the interlocking column when the adjusting column separates. This prevents the wind tunnel body from vibrating due to the passage of airflow during the test, which could cause the adjusting column to vibrate and deflect for a long time.

The limiting shaft 402 is a circular shaft arranged at the top of the adjusting column 4, and the protruding part of the limiting shaft 402 is on the inner wall of the adjusting column 4. The interlocking groove 403 is a circular shaft groove connecting the limiting shaft 402, and the inner wall of the opening of the interlocking groove 403 is provided with a threaded groove. The lifting column 404 is a disc connected to the top of the adjusting column 4 and interlocked with the interlocking column 401.

[0039] Furthermore, the interlocking column 401 is also provided with a fitting groove 4011 and a limiting groove 4012. The fitting groove 4011 is an arc-shaped groove on the side wall of the interlocking column 401, and the fitting groove 4011 cooperates with the protruding inner wall portion of the limiting shaft 402 to adjust the column 4. The limiting groove 4012 is a groove with an inwardly inclined arc extending on one side of the surface of the fitting groove 4011.

[0040] Furthermore, the limiting shaft 402 is also provided with a rotating disk 4021, a rotating shaft 40211, a rotating annular groove 40212, a limiting disk 4022 and a deflection shaft 40222. The rotating disk 4021 is several circular disks connected in the limiting shaft 402, the rotating shaft 40211 is a circular shaft connected to the limiting shaft 402 at the top, the rotating annular groove 40212 is a circular groove at the bottom of the rotating disk 4021, the limiting disk 4022 is several circular disks with smaller diameters connected to the middle part of the limiting shaft 402, and the top of the limiting disk 4022 is fitted with the rotating disk 4021, the deflection shaft 40222 is a circular shaft connected to the limiting disk 4022, and the part of the deflection shaft 40222 protruding from the top of the limiting disk 4022 cooperates with the rotating annular groove 40212.

[0041] Furthermore, the side wall of the rotating disk 4021 is threadedly matched with the opening of the inner wall of the fitting groove 403 .

[0042] Furthermore, the limiting plate 4022 is further provided with a limiting block 40221 . The limiting block 40221 is an arc-shaped protrusion extending obliquely from one side of the limiting plate 4022 , and the limiting block 40221 cooperates with the limiting groove 4012 .

[0043] Furthermore, the top side wall of the deflection shaft 40222 is threadedly engaged with the inner wall of the rotating ring groove 40212 , and the deflection shaft 40222 is arranged near one side of the limiting plate 4022 .

[0044] Furthermore, a method for splicing and installing a steel structure wind tunnel body is provided, wherein the steps are as follows:

[0045] In the first step, the wind tunnel body 1 is prefabricated with connecting reinforcement ribs 2, and then fixed support columns 201 are set at the bottom of the reinforcement ribs 2. After completion, the wind tunnel body 1 is hoisted;

[0046] In the second step, when hoisting the wind tunnel body 1, the base 5 is installed at the location where it needs to be installed, and then the base 5 is connected to the concrete through anchor bolts. At the same time, the connecting plate 3 is installed on the top of the base 5, and the adjusting column 4 is set in the connecting plate 3 to complete the installation of the lower support system;

[0047] In the third step, after the base 5, the connecting plate 3 and the adjusting column 4 are installed to form the lower support system, the height of the connecting plate 3 and the wind tunnel body 1 is changed by adjusting the height of the adjusting column 4 to adjust the support height of the wind tunnel body 1, thereby leveling the wind tunnel body 1;

[0048] In the fourth step, after the height adjustment of the adjustment column 4 is completed, the support column 201 provided on the reinforcement rib 2 on the wind tunnel body 1 will be connected to the reserved bolt hole on the connecting plate 3, thereby completing the leveling and installation of the wind tunnel body 1. At the same time, the setting of the reinforcement rib 2 can increase the downward force transmission area, reduce stress, and avoid stress concentration, so that the reinforcement rib 2 can evenly transmit the uniform surface load downward, so that when installing some wind tunnel bodies 1 with different sizes and weights, they can also be stably installed and bear the load.

[0049] In the third step, when the height of the adjusting column 4 is adjusted, the limiting shaft 402 is rotated by the extension of the height of the adjusting column 4, so that the limiting plate 4022 in the limiting shaft 402 will loosen and rotate eccentrically, thereby limiting the connection with the interlocking column 401 in the adjusting column 4, so as to increase the tensile strength of the adjusting column 4 after separation from the interlocking column 401 and avoid deviation and tilt due to vibration.

[0050] The following is a specific implementation process of the present invention. First, a large and heavy wind tunnel body 1 is connected to the reinforcing rib 2, and then the reinforcing rib 2 is connected to the support column 201 at the bottom. The connecting plate 3 on the support column 201 is fixedly connected to the base 5 at the bottom, so that it can support the wind tunnel body. At the same time, because of the presence of the reinforcing rib, when carrying some wind tunnel bodies 1 that are too large and heavy, it can be made more stable when bearing weight without shaking. At the same time, the adjusting column 4 set in the connecting plate 3 can change its height through a certain extension and contraction, so that it can be installed When the wind tunnel body 1 is adjusted, it can be leveled to a certain extent, so that the installation of the wind tunnel body 1 is more accurate. When the adjusting column 4 is telescopically supported and leveled, when the adjusting column 4 is lifted and lowered from the side wall of the interlocking column 401 through the internal jack, the lifting column 404 on the top of the adjusting column 4 will be driven to lift and lower. When the lifting column 404 is lifted and lowered, the limiting shaft 402 will be withdrawn from the interlocking groove 403. When the limiting shaft 402 is withdrawn from the interlocking groove 403, the rotating disk 4021 in the middle will be threadedly fitted into the opening of the inner wall of the interlocking groove 403, so that the rotating disk 4021 on the limiting shaft 402 fits the interlocking groove 403. When the thread extends out, it rotates. When the rotating disk 4021 rotates, the rotating ring groove 40212 at the bottom engages with the tooth marks of the deflection shaft 40222 on the limiting disk 4022, so that when the rotating disk 4021 rotates, the rotating ring groove 40212 engages with the deflection shaft 40222 and rotates around, thereby driving the deflection shaft 40222 to rotate. When the deflection shaft 40222 rotates, it drives the entire limiting disk 4022 to rotate. Because the deflection shaft 40222 is connected to one side of the limiting disk 4022, the rotation of the limiting disk 4022 is centered around the deflection shaft 40222. This causes the limit plate 4022 to rotate eccentrically, allowing the limit block 40221 on one side to protrude from the surface of the limit shaft 402 and then be embedded in the limit groove 4012 of the fitting groove 4011 for connection, so that the limit shaft 402 and the embedded column 401 are limitedly connected, so that when the adjusting column 4 is raised and lowered, the vibration of the wind tunnel body during the experiment will not cause the connection between the embedded column 401 to be skewed and worn, making the telescopic support of the adjusting column 4 more stable, and the rotating disk 4021 and the limit plate 4022 arranged in sections on the limit shaft 402 can also perform different limitations according to the raising and lowering height of the adjusting column 4.

[0051] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
