By setting a support frame II22 on the front end face of the chain belt I2112, when the chain belt I2112 and the chain belt II2122 are in contact with the left and right sides of the rotating table 14, the chain belt III2212 slides in the slide groove III6 in the support frame II22 through the sliding wheel III2213, and one side of the support frame II22 is fixedly connected to the front end face of the chain belt II2122, and the short side of the other side of the support frame II22 and the connecting piece 16 of the chain belt I2112 form an integrated structure after the operating platform 2X is axially closed, so that the chain belt III2212 extends into the connecting piece 16 (the connecting piece 16 is provided with a sliding groove for the sliding wheel III2213 to slide), thereby realizing the closing of the operating platform 2 in the Y-axis direction.

[0052] In the above technical solution, the support assembly 1 has four degrees of freedom in space, and the support assembly 1 includes: a support frame 11, a Z-direction displacement component 12 arranged on the support frame 11 for lifting and lowering the rotating table 14 in space, an X-direction displacement component arranged on the Z-direction displacement component for moving the rotating table 14 forward and backward in space, a Y-direction displacement component arranged on the X-direction displacement component for moving the rotating table 14 left and right in space, and a rotating table 14 arranged on the Y-direction displacement component for installing the external test model 144. With this technical solution, the support assembly 1 is designed as a highly flexible and multifunctional platform for accurately controlling and adjusting the position and posture of the external test model 144 in an experimental or test environment. Specifically, the support assembly 1 realizes the full range of movement and rotation of the rotating table 14 (and the external test model 144 installed on the rotating table 14) in three-dimensional space through its four degrees of freedom design.

[0053] In the above technical solution, the Z-direction displacement component 12 includes: a pair of guide rails Ⅰ121 arranged in the vertical direction of the support frame 11, a pair of screw rod assemblies Ⅰ122 arranged on the support frame 11, a support seat Ⅰ123 is slidably connected to the guide rails Ⅰ121, and the support seat Ⅰ123 is fixedly connected to the sliding block Ⅰ124 of the screw rod assembly Ⅰ122; wherein, the X-direction displacement component is arranged on the upper surface of the support seat Ⅰ123.

[0054] In the above technical solution, the X-direction displacement component includes: guide rails II arranged in pairs on both sides of the upper surface of the support seat I 123, a screw assembly II arranged on the upper surface of the support seat I 123 and located between the guide rails II, the guide rail II is slidably connected to the support seat II, and the support seat II is fixedly connected to the sliding block II arranged on the screw assembly II;

[0055] The Y-direction displacement component is arranged on the upper surface of the support seat II, and the screw assembly II and the guide rail II are mutually horizontal in the spatial direction. With this technical solution, the support seat II is driven by the screw assembly II, and the sliding block II drives the guide rail II to move left and right, thereby realizing the precise control of the rotating table 14 in the X-axis direction.

[0056] In the above technical solution, the Y-direction displacement component includes: guide rails III arranged in pairs on both sides of the upper surface of the support seat II, a screw assembly III arranged on the upper surface of the support seat II and located between the guide rails III, a support plate 13 is slidably connected to the guide rail III, and the support plate 13 is fixedly connected to the sliding block III arranged on the screw assembly III;

[0057] Among them, the guide rails II and III are perpendicular to each other in the spatial direction, the rotating table 14 is arranged on the upper surface of the support plate 13, and the screw assembly III and the guide rail III are horizontal to each other in the spatial direction. With this technical solution, the sliding block III drives the support seat III to move forward and backward on the guide rail III through the drive of the screw assembly III. Combined with the design of the X-axis displacement component and the Z-axis displacement component 12, the support assembly 1 can realize the control of the three degrees of freedom of the rotating table 14 in the X-axis, Z-axis and Y-axis. The rotating table 14 can be freely moved and positioned in three-dimensional space to meet various complex processing, installation and other requirements.

[0058] In the above technical solution, the rotating platform 14 includes: a mounting member 141 disposed on the support plate 13, the mounting member 141 is a hollow structure, a rotating motor 142 is disposed inside the mounting member 141, and the output end of the rotating motor 142 is fixedly connected to a mounting plate 143 for mounting an external test model 144.

[0059] Among them, the three degrees of freedom of the X-axis, Z-axis and Y-axis in the support component 1 are all realized by the screw assembly and the slider. Figure 7-Figure 8 The Z-axis degree of freedom of the support assembly 1 is described in detail, and the implementation methods of the other degrees of freedom are the same as those of the Z-axis degree of freedom, so no further explanation will be given here.

[0060] In the above scheme, it also includes: support wheels 10 arranged in pairs at the bottom of the support frame II, and the surface of the support wheels 10 abuts against the crossbeam 15 at the top of the support assembly. With this technical solution, the support wheels 10 ensure that the support frame II can get additional support and stability when the operating platform is closed. Due to the close contact between the support wheels 10 and the crossbeam 15, they can prevent the platform from shaking or tilting unnecessarily during operation, thereby improving the safety and work efficiency of the staff. At the same time, the use of the support wheels 10 reduces the direct friction between the support frame II and the crossbeam 15. The noise and vibration caused by friction are reduced.

[0061] A method for using an operating platform, applied to the operating platform 2 for installing a wind tunnel test model, the method comprising:

[0062] Step 1: First, the Y-direction bearing component 221 of the operating platform 2 is moved by the external control unit to realize the opening of the operating platform 2 in the Y-axis direction, and then the X-direction bearing component I 211 and the X-direction bearing component II 212 on the operating platform 2 are moved to realize the opening in the X-axis direction;

[0063] Finally, the external control unit issues a command, and the support assembly 1 moves the test model 144 to a position where it is docked with the external model;

[0064] Step 2: After the test model 144 moves to the specified position, the control unit controls the X-axis bearing assembly I211 and the X-axis bearing assembly II212 to move. When the proximity switch I3 is close to the rotating table 14, the proximity switch I3 gives a feedback signal to the control unit, and the X-axis bearing assembly I211 and the X-axis bearing assembly II212 stop moving, and the operating platform 2 is closed in the X-axis direction.

[0065] Step 3: After the operating platform 2 completes the closing in the X-axis direction, the control unit controls the Y-axis bearing assembly 221 to move. When the proximity switch II (not shown in the figure) is close to the rotating table 14, the proximity switch II gives a feedback signal to the control unit, the Y-axis bearing assembly 221 stops moving, and the operating platform 2 is closed in the Y-axis direction.

[0066] Working principle:

[0067] When the test model 144 needs to be docked with an external device, the control unit first sends a moving command to the Y-axis bearing component 221 of the operating platform 2, and the sliding wheel III2213 of the chain plate belt III2212 of the Y-axis bearing component 221 moves along the slide groove III6 in the support frame II22, and the operating platform 2 opens in the Y-axis direction. Then, the X-axis bearing component I211 and the X-axis bearing component II212 are synchronously and accurately opened in the X-axis direction under the command of the control unit. When the operating platform 2 is fully opened, the support component 1 will accurately move the test model 144 to the docking position with the external device after receiving the command of the control unit;

[0068] When the test model 144 moves to the specified position, the control unit will instruct the X-direction bearing assembly I211 and the X-direction bearing assembly II212 to start moving toward the rotating table 14 and close. When the distance between the proximity switch I3 and the rotating table 14 reaches the preset threshold, the proximity switch I3 will immediately send a feedback signal to the control unit. After receiving this signal, the control unit will immediately stop the movement of the X-direction bearing assembly, and the operating platform 2 will complete the closing in the X-axis direction. After completing the closing in the X-axis direction, the control unit will continue to issue instructions to control the Y-direction bearing assembly 221 to move toward the rotating table 14. During the movement of the Y-direction bearing assembly 221, when the distance between the proximity switch II and the rotating table 14 reaches the preset threshold, the proximity switch II will also send a feedback signal to the control unit. After receiving this signal, the control unit will immediately stop the movement of the Y-direction bearing assembly 221, thereby achieving the closing in the Y-axis direction. When the operating platform 2 is closed in the X-axis direction and the Y-axis direction, the operator can stand on the operating platform 2 to perform various operations and replace the test model 144.

[0069] Although the embodiments of the present invention have been disclosed as above, they are not limited to the applications listed in the specification and the implementation modes, and they can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented.
