Technical Field
[0001] This invention belongs to the field of wind tunnel testing technology, specifically relating to a wind tunnel double-support device installation and transport vehicle and its usage method. Background Technology
[0002] In the wind tunnel test preparation environment, the support method for conventional balance support devices is simple; they only need to be placed on a handcart within the wind tunnel test section. However, high-load tests pose unique challenges to the support method of high-load balance dual-support devices (hereinafter referred to as dual-support devices). Currently, the dual-support device is still placed on a handcart to support the high-load balance. The disadvantages of this method are: the dual-support device is relatively large, making it difficult to adjust the offset of the dual-support device in all twelve directions; the dual-support device is heavy, making it difficult to raise and lower the handcart, posing certain safety hazards; the dual-support device is wide, requiring two handcarts and multiple people for installation, resulting in high labor costs and significant resource consumption.
[0003] Currently, there is an urgent need to develop a wind tunnel double-support device installation and transportation vehicle and its usage method. Summary of the Invention
[0004] One technical problem to be solved by the present invention is to provide a wind tunnel double support device installation and transport vehicle, and another technical problem to be solved by the present invention is to provide a method of using the wind tunnel double support device installation and transport vehicle, so as to overcome the defects of the prior art.

[0006] The dual-support device includes a strut connected to a large-load balance, a support for the strut, and a rectifier cone for profile rectification.
[0007] The support fixture includes a support block, a rotary platform, an X-axis translation platform, a yaw adjustment knob, and a yaw adjustment platform; The rotary platform, X-axis translation platform, and yaw adjustment platform are all square platforms. Several support blocks are welded to the upper surface of the rotary platform. Each support block is adaptively designed and processed according to the support points of the double support device. The double support device is supported above each support block. A cylinder is welded to the lower surface of the rotary platform. The cylinder is clearance-fitted with the mounting holes of the X-axis translation platform. Square protrusions extend from the left and right sides of the rotary platform. Yaw adjustment platforms extend from the corresponding positions on the left and right sides of the X-axis translation platform. The square protrusions are located above the central axis of the corresponding yaw adjustment platforms. Mounting seats are fixed on the left and right yaw adjustment platforms. Yaw adjustment knobs that are horizontally oriented towards the corresponding square protrusions are screwed into the left and right mounting seats. The X-axis translation assembly includes an X-axis slider, an X-axis slide rail, an X-axis slide rail clamp, an X-axis slider limiter, and a Y-axis translation platform. Two symmetrical X-axis slide rails are set on the Y-axis translation platform. The X-axis slide rails are fixed to the Y-axis translation platform by several countersunk screws evenly distributed along the X-direction. X-axis slider limiters are set at the front and rear ends of the X-axis slide rails and are fixed at the four corners of the Y-axis translation platform. Two X-axis sliders and two corresponding X-axis slide rail clamps are inserted into each X-axis slide rail. The X-axis translation platform is fixed above the four X-axis sliders. The X-axis slider has a gate-shaped structure with a slot in the middle of the lower surface, which allows it to be inserted into the X-axis slide rail. The X-axis slide rail clamp is also a gate-shaped structure with a slot in the middle of the lower surface. It is inserted into the X-axis slide rail through the slot. The side of the X-axis slide rail clamp is equipped with a positioning handle. By rotating the positioning handle, the X-axis slide rail clamp is locked and positioned to prevent the corresponding X-axis slider from sliding beyond the positioning. The X-axis slider limiter prevents the X-axis slider from slipping off the X-axis slide rail. The X-axis translation platform is also equipped with an X-axis translation handle on its side. The Y-axis translation assembly includes a Y-axis slider limiter, a Y-axis slide rail, a Y-axis slider, a pitch and roll lifting platform, a Y-axis sliding guide, a Y-axis bolt, a Y-axis bearing seat, and a Y-axis translation handle; The pitch and roll lifting platform is a square platform; a through hole is set at the midpoint of the front edge of the pitch and roll lifting platform, and two through holes are set symmetrically at the top and bottom of the rear edge; two Y-axis slide rails are set on the pitch and roll lifting platform with front and rear symmetry; the Y-axis slide rails are fixed to the pitch and roll lifting platform by several countersunk screws evenly distributed along the Y direction; Y-axis slider limiters are set at both ends of the Y-axis slide rails, and the Y-axis slider limiters are fixed at the four corners of the pitch and roll lifting platform; a Y-axis slider is inserted into each Y-axis slide rail; a Y-axis translation platform is fixed above the Y-axis slider; A groove parallel to the two Y-axis slide rails is provided between them. A Y-axis sliding guide and a Y-axis bearing seat are fixed sequentially along the groove from the inside to the outside. The upper surface of the Y-axis sliding guide is connected to the Y-axis translation platform through a slot. A threaded hole is opened in the center of the Y-axis sliding guide. A bearing is installed in the Y-axis bearing seat. A Y-axis bolt passes through the Y-axis sliding guide and the bearing. The front thread of the Y-axis bolt matches the threaded hole in the center of the Y-axis sliding guide. The rear cylindrical part of the Y-axis bolt mates with the bearing column of the Y-axis bearing seat. A Y-axis translation handle is fixed at the top of the cylinder. An isolation gap is provided between the groove and the Y-axis bolt.
[0008] Furthermore, the control system includes a roll angle adjustment rod, an upper platform of the control system, a lift, an electric cylinder, a lower platform of the control system, a dustproof protective cover, a control cabinet, drive rollers, and a lead screw height adjuster; The upper platform and lower platform of the control system are square platforms that are parallel to each other vertically. The control system platform has through holes corresponding to the through holes of the pitch and roll lifting platform. A roll angle adjustment rod is installed between the corresponding through holes. The lower end of the roll angle adjustment rod is fixed to the upper surface of the control system platform by a threaded connection. The upper section of the roll angle adjustment rod is equipped with two nuts, the upper nut is located above the pitch and roll lifting platform, and the lower nut is located below the pitch and roll lifting platform. Between the upper platform and the lower platform of the control system, one elevator is installed at each of the four corners, an electric cylinder is installed in the center, a control cabinet is installed at the edge, and a dustproof protective cover is installed along the circumference; the dustproof protective cover protects the elevator and the electric cylinder from dust; Drive rollers and lead screw height adjusters are installed at the four corners of the bottom surface of the platform under the control system.
[0009] The method of using the wind tunnel double-support device installation and transport vehicle of the present invention includes the following process: The double support device is placed on the installation and transport vehicle; The control cabinet drives the rollers to move, which in turn moves the installation and transport vehicle. The X-axis position of the dual support device can be changed by pulling the X-axis translation handle along the X-axis; By rotating the Y-axis translation handle and turning the Y-axis bolt, the Y-axis sliding guide is moved along the groove, thus changing the Y-axis position of the double support device. The electric cylinders are controlled by the control cabinet to drive the four lifting platforms to move up and down synchronously, thereby changing the Z-axis position of the double support device. By adjusting the two yaw adjustment knobs on the left and right sides, the square protrusion is pushed to rotate around the cylinder, thereby making the rotating platform rotate around the cylinder and changing the yaw angle of the double support device. By adjusting the position of the three lower nuts, the roll and pitch angles of the tilt and roll lifting platform can be adjusted, thereby changing the roll and pitch angles of the double support device. During maintenance, the dust cover was removed to repair the elevator and electric cylinder.
[0010] The wind tunnel double-support device installation and transport vehicle of the present invention integrates and optimizes the double-support device attitude adjustment platform and auxiliary tooling based on a mobile lifting platform vehicle; by setting screw height adjusters at the four bottom corners of the installation and transport vehicle, the load-bearing capacity of the installation and transport vehicle is improved; the lifting and moving of the installation and transport vehicle is realized by driving the electric cylinder through the control cabinet; by matching the widened installation and transport vehicle with the double-support device, the number of workers is reduced, the work efficiency is improved, and the goal of one worker working independently is achieved.
[0011] The wind tunnel double support device installation and transport vehicle of the present invention uses a control cabinet to control the movement and overall lifting of the installation and transport vehicle, and manually adjusts the double support device in six directions for translation, roll, pitch and yaw by adjusting the double support device attitude adjustment platform, so as to achieve precise installation of the large load balance.
[0012] In summary, the wind tunnel double-support device installation and transportation vehicle and its usage method of the present invention achieve convenient operation through integrated design and high integration, overcoming the problems of low load-bearing capacity, inability to adjust precisely, installation risks, and high resource consumption of handcarts. It provides a convenient, safe, reliable, and precision-adjustable installation and transportation technical solution for the balance double-support device of large load test, and has practical engineering value.
