[0022] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0023] The directions or positional relationships indicated by the terms "up", "down", "front", "back", "left" and "right" appearing in the embodiments of the present invention are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they should not be understood as limiting the present invention.

[0024] In the description of the present invention, it should be noted that, unless otherwise clearly stipulated and limited, the terms "setting", "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection; it can be directly connected or indirectly connected through an intermediate medium; for ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] If there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features.

[0026] The embodiment of the present invention is an automatic tilt adjustment type launcher for cold launch test, such as Figure 1 As shown, the launch tube fixing platform 1 includes a launch tube fixing platform 1, a rotating support 2, and an automatic retractable device 5. The launch tube fixing platform 1 is used to mount the launch tube 8 and the initial chamber 9. The launch tube fixing platform 1 is connected to the rotating support 2, and the launch tube fixing platform 1 and the rotating support 2 move synchronously. One side of the rotating support 2 is connected to the automatic retractable device 5, which is used to drive the rotating support 2 to rotate a certain angle relative to the ground. During testing, the launch tube 8 and the initial chamber 9 are mounted on the launch tube fixing platform 1. The automatic retractable device 5 drives the rotating support 2 to rotate, so that the rotating support 2 forms a predetermined angle with the bottom surface, thereby adjusting the launch tube to a predetermined inclination angle for the launch test. Since the launch tube fixing platform 1 of the automatic tilt adjustment type launch stand for cold launch test of the present invention is connected to the rotating support 2, the automatic telescopic device 5 is used to drive the rotating support 2 to rotate relative to the ground, so the launch tube 8 can be tilted and adjusted as a whole with the rotating support 2. During the launch tilt angle debugging process of the launch tube 8, there is no need to frequently disassemble and repair the launch tube, which shortens the test preparation period and improves the convenience of system debugging. At the same time, since the launch tilt angle of the launch tube 8 can rotate as a whole with the rotating support 2, there is no need to build a field with a specific slope.

[0027] Alternatively, as Figure 1 、 Figure 2As shown, the launch tube fixing platform 1 includes a first support plate 101 and a plurality of legs 103. A through hole is opened on the first support plate 101, and the through hole is used to install the launch tube 8 and the initial volume chamber 9. The first support plate 101 is connected to each leg 103, and each leg 103 is arranged under the first support plate 101. In this embodiment, there are four legs 103, and the first support plate 101 is a quadrilateral. The four legs 103 are respectively connected to the four corners of the first support plate 101.

[0028] Optionally, the launch tube mounting platform 1 further includes a set of first support beams 102, which are arranged relative to and below the first support plate 101. The first support plate 101 and each of the first support beams 102 are provided with a plurality of connection holes, and the connection holes on the first support beams 102 correspond one-to-one with the connection holes on the first support plate 101. Each leg 103 passes through the corresponding set of connection holes, and each leg is provided with a locking nut 104 above the first support plate 101 and below the first support beam 102. The two locking nuts 104 interconnect the first support plate 101, the first support beam 102, and the legs 103. To further ensure the strength of the launch tube mounting platform 1, the set of first support beams 102 are welded to the support plate 101. The provision of the first support beam 102 improves the strength of the launch tube fixing platform 1. At the same time, since each leg is provided with a locking nut 104 above the first support plate 101 and below the first support beam 102, the height of the support plate 101 from the ground can be adjusted by moving the two locking nuts 104, the first support plate 101 and the first support beam 102 on the leg 103.

[0029] Alternatively, as Figure 1 、 Figure 3 As shown, the rotating support 2 is located below the launch tube fixing platform 1. The rotating support 2 includes a second support plate 201 and a second support beam 203. The second support plate 201 is a flat plate. The second support plate 201 and the second support beam 203 are connected by multiple bolts. The second support beam 203 is arranged below the second support plate 201. The second support plate 201 and the first support plate 101 are parallel to each other. The bottom of each support leg 103 is connected to the second support beam 203 by bolts.

[0030] Optionally, the rotating support 2 also includes a reinforcing beam 202, which is cross-shaped. The second support beam 203 is a frame-type structure. The reinforcing beam 202 is located at the center of the second support beam 203. Each end of the reinforcing beam 202 is connected to the second support beam 203 by multiple bolts. The reinforcing beam 202 and the second support beam 203 are located in the same plane.

[0031] Alternatively, as Figure 1 、 Figure 6As shown in the figure, the automatic telescopic device 5 includes a motor driver 506, a motor 505, a reducer 504, a coupling 503, a drive shaft 500 and a worm gear telescopic screw 501 connected in sequence, the output shaft 502 is connected to the worm gear telescopic screw 501, the worm gear telescopic screw 501 drives the output shaft 502 to move upward or downward, and the output shaft 502 is connected to one side of the second support beam 203. Specifically, the apparatus further includes a mounting base 507, on which the automatic telescopic device motor 505, a reducer 504, and a worm gear telescopic screw 501 are all mounted. The reducer 504 is connected to the drive shaft 500 via a coupling 503, and the worm gear telescopic screw 501 is connected to the output shaft 502 via a screw support lug. The automatic telescopic device motor 505 rotates, driving the drive shaft 500 to rotate via the coupling 503, thereby changing the length of the worm gear telescopic screw 501. The change in the length of the worm gear telescopic screw 501 drives the output shaft 502 to move up and down, thereby driving the rotating support 2 to rotate a certain angle relative to the ground, thereby adjusting the launch tube's inclination angle. Since the length of the worm gear telescopic screw 501 can be continuously changed within a certain range, the launch tube's launch inclination angle can be continuously adjusted within a certain range, thereby meeting different test requirements.

[0032] Alternatively, as Figure 4 、 Figure 5As shown, an embodiment of the present invention is an automatic tilt-adjusting launcher for cold launch test, which further includes a self-measuring angle shaft device 3, a fixed support 4 and an electronic control host 6. One or more self-measuring angle shaft devices 3 are provided. In this embodiment, two self-measuring angle shaft devices 3 are provided. Each angle-measuring shaft device 3 includes a rotating shaft 301 and an angle encoder 308. The angle encoder 308 is connected to the rotating shaft 301. The angle encoder 308 is used to obtain the rotation angle of the rotating shaft 301 and transmit the rotation angle to the electronic control host 6. The movable shaft 301 is rotatably connected to the fixed support 4. The rotating shaft 301 is connected to the second support beam 203 and rotates synchronously with the second support beam 203. The second support beam 203 is connected to the rotating shaft 301 at the opposite side of the output shaft 502. When the output shaft 502 drives the second support beam 203 to rotate, the second support beam 203 drives the rotating shaft 301 to rotate synchronously relative to the fixed support 4. The electronic control host 6 controls the motor driver 506 based on the rotation angle information. The automatic telescopic device motor 505 is a servo motor. Specifically, the self-detecting angle rotating shaft device 3 also includes a sleeve 302, a gasket 303, a threaded pin 304, a retaining ring 305, a coupling 306, and a protective cover 307. The rotating shaft 301 and the sleeve 302, gasket 303, and retaining ring 305 are coaxially connected. The angle encoder 308 is threadedly connected to the protective cover 307 and is connected to the rotating shaft 301 via the coupling 306. During operation, when the automatic telescopic device 5 drives the rotating support 2 to rotate, the angle encoder 308 obtains the rotation angle of the rotating shaft 301, that is, the tilt angle of the launch tube, and transmits the tilt angle to the electronic control host 6. The target tilt angle is preset in the electronic control host 6. The electronic control host 6 sends a control instruction to the motor driver 506 based on the above-mentioned tilt angle transmitted in real time, controls the rotation of the automatic telescopic device motor 505, and thus realizes the adjustment of the tilt angle, so that the tilt angle of the launch tube can be automatically adjusted.

[0033] Optionally, the fixed support 4 is a frame-type structure. In the initial position, the fixed support 4 and the rotating support 2 are located in the same plane, and the fixed support 4 is arranged on the periphery of the rotating support 2. Since the fixed support 4 is arranged on the periphery of the rotating support 2, the length and width of the fixed support 4 are relatively large, and the anti-overturning force arms of the fixed support 4 in the length and width directions are sufficiently long. The entire system can achieve posture stability without the need for ground-based pulling fixed structures. At the same time, the fixed support 4 has a large ground contact area, which reduces the ground pressure of the launch system, improves system stability, prevents overturning, and reduces ground reliance.

[0034] Optionally, the fixed support 4 is provided with a first lug 41, to which the rotating shaft 301 is rotatably connected via a sleeve 302. A second lug 208 is provided on the second support beam 203 of the rotating support 2. The second lug 208 is sleeved on the rotating shaft 301, and a threaded pin 304 connects the second lug 208 to the rotating shaft 301, enabling synchronous rotation of the rotating shaft 301 and the rotating support 2. The rotating support 2 also includes a drive rod 204, which is connected to the second support beam 203 and is higher than the second support beam 203. The drive rod 204 is provided with a third lug, to which the output shaft 502 is connected via the third lug, thereby driving the rotating support 2 to rotate. The provision of the first lug 41, the second lug 208, the drive rod 204, and the third lug facilitates installation of the automatic tilt adjustment launcher for cold launch testing of the present invention.

[0035] like Figure 7 As shown, the electronic control host 6 includes a processor 601, an LCD touch screen 602, a lithium battery 603, a power adapter 604, an analog input port 605, a serial port module 606, a wireless module 607 and a GUI interface 608; the lithium battery 603 is connected to the mains power through the power adapter 604; the electronic control host 6 communicates with other electrical devices through the wireless module 607, the angle encoder 308 transmits the voltage signal to the processor 601 through the analog input port 605, and the processor 601 communicates with the motor driver 506 through the serial port module 606, sends control signals to the motor driver 506, and controls the speed and position of the motor 505 of the automatic telescopic device.

[0040] Step 4: Connect the rotating support 2 to the fixed support 4 through the self-measuring angle shaft device 3 and the automatic telescopic device 5;

[0041] During the test, the rotating support 2 and the launch tube 8 will rotate integrally with the launch tube fixing platform 1 around the axis of the first lug 41 of the fixing support 4. During the test, the launch tube 8 can be adjusted to its launch angle without disassembly.

[0042] The process of setting an arbitrary launch inclination angle is as follows:

[0043] Step 1: Use AC power to power the motor driver 506 and charge the electronic control host 6 through the power adapter 604;

[0044] Step 2: Turn on the electronic control host 6 and start the user interface; test the communication status of the electronic control host 6 through the LCD touch screen 602;

[0045] Step 3: Input the launch tube target tilt angle into the electronic control host 6 according to the test requirements and the current tilt angle displayed in the electronic control host 6;

[0046] Step 4: The electronic control host 6 sends the adjustment signal to the motor driver 506, and the automatic telescopic device motor 505 rotates to the target angle position according to the instruction requirement;

[0047] Step 5: The worm gear telescopic screw 501 extends and drives the rotating support 2 and the rotating shaft 301 to rotate around the axis of the first lug 41 of the fixed support 4 to a target angle;

[0048] Step 6: The angle encoder 308 sends the real-time tilt angle data value to the electronic control host 6 through the analog input port 605, and the GUI interface 608 displays the value of the launch tilt angle in real time.
