Through the three tilt sensors, the horizontal states of the three electric control telescopic legs 12 can be monitored in real time, and the monitoring results can be transmitted to the tripod controller. Then the tripod controller can control the motor inside the leg to drive the leg to telescope according to the monitoring results, thereby automatically adjusting the horizontal state of the legs to ensure the balance and stability of the overall electric control tripod 1.

[0023] As Figure 3 shown, the support wheel 14 includes a support plate 141 and a support roller 142. The support roller 142 is installed on the bottom surface of the support plate 141. At both ends of the top surface of the support plate 141, ear plates 143 are fixed. The two ear plates 143 are respectively rotatably connected to both sides of the bottom end of the electric control telescopic leg 12. Two adjustment holes 144 are provided on the ear plates 143 along the rotation direction of the ear plates 143, and threaded holes corresponding to the adjustment holes 144 are provided on the electric control telescopic legs 12. By rotating the ear plates 143, different adjustment holes 144 are made to correspond to the threaded holes, and then screws are passed through the adjustment holes 144 and connected to the threaded holes, so that the position of the support wheel 14 can be adjusted. When it is necessary to move the electric control tripod 1, the electric control tripod 1 can be supported by rolling through the support rollers 142. When it is necessary to fix the electric control tripod 1, the support wheel 14 can be retracted.

[0024] As Figure 6 、 Figure 7As shown in the figure, the double-variable-stroke electric control slide rail 3 includes a rail 31, an outer hub 32, an inner hub 33, a connecting plate 34, a synchronous belt 35, and a driver 36. There are two rails 31, and the two rails 31 are arranged in parallel. The ends of the two rails 31 are fixedly connected through a mounting seat 17. Outer hubs 32 are correspondingly arranged on the outer sides of the two rails 31, and the tops of the two outer hubs 32 are fixedly connected through a connecting plate 34. The pitching bracket 6 is fixed to the connecting plate 34 by bolts, which is convenient for disassembly and assembly. An outer roller is installed on the outer hub 32, and the outer hub 32 is in rolling connection with the top and bottom of the corresponding rail 31 through the outer roller. The two sides of the inner hub 33 correspond to the two rails 31 one by one. Inner rollers are installed on both sides of the inner hub 33, and both sides of the inner hub 33 are in rolling connection with the top and bottom of the corresponding rail 31 through the inner rollers. Synchronous belts 35 are provided between the inner hub 33 and the two mounting seats 17. Synchronous wheels are installed on the two mounting seats 17. The two synchronous belts 35 are respectively wound around the two synchronous wheels. The two ends of the two synchronous belts 35 are respectively fixedly connected to the inner hub 33 and the connecting plate 34. The driver 36 is installed on the mounting seat 17 at one end of the rail 31 and is used to drive the synchronous belt 35 to move.

[0025] As Figure 8 , Figure 9 shown in the figure, the driver 36 includes a drive box 361, a drive motor 362, a drive gear 363, a transmission shaft 364, a worm gear, a worm 365, and a motor controller. One end of the drive box 361 is fixed to the mounting seat 17 at one end of the rail 31. The transmission shaft 364 is installed in the drive box 361 through a bearing 21. A drive gear 363 and a worm gear are installed on the transmission shaft 364. The drive motor 362 and the motor controller are both installed in the drive box 361. The drive motor 362, the motor controller, and the battery 8 are electrically connected in sequence. A worm 365 meshing with the worm gear is connected to the output end of the drive motor 362. The outer surface of the synchronous belt 35 is provided with teeth. An opening is provided at one end of the drive box 361 connected to the mounting seat 17. The drive gear 363 passes through the opening and meshes with the teeth on the synchronous belt 35. A proximity switch 22 corresponding to the outer hub 32 is also installed at one end of the drive box 361 connected to the mounting seat 17. The proximity switch 22 is electrically connected to the motor controller. The drive motor 362 is a forward and reverse motor. During the test, the motor controller controls the drive motor 362 to drive the worm 365 to rotate. The worm 365 drives the transmission shaft 364 to rotate through the worm gear. The transmission shaft 364 drives the synchronous belt 35 to move through the drive gear 363, and then drives the outer hub 32 to move. By reversing the drive motor 362, the RCS tester can be driven to reciprocate with the outer hub 32. The proximity switch 22 can detect the distance between the outer hub 32 and the driver 36 in real time. When the outer hub 32 moves to the ends of the two ends of the rail 31, the motor controller can control the drive motor 362 to reverse according to the detection result of the proximity switch 22, thereby realizing the reciprocating movement of the RCS tester 4.

[0026] As Figure 4 , Figure 5 , Figure 7 shown, sliders 10 and supports 15 are respectively fixed at both ends of the adapter post. The bottom end of the adapter rod 2 is detachably arranged on the top of the control box 11 through the slider 10, and the bottom of the inner hub 33 is detachably arranged on the support 15. Specifically, a first chute 9 is provided on the top of the control box 11. The slider 10 is slidably connected to the first chute 9. A first opening is provided on one side of the first chute 9 at the top of the control box 11. A first locking block 16 is provided at the first opening. The first locking block 16 is connected to the control box 11 by screws and abuts against the slider 10. A second chute 18 is provided on the top of the support 15. A sliding seat 19 slidably connected to the second chute 18 is fixed at the bottom of the inner hub 33. A second opening is provided on one side of the second chute 18 at the top of the support 15. A second locking block 20 is provided at the second opening. The second locking block 20 is connected to the support 15 by screws and abuts against the sliding seat 19. When assembling the double variable stroke electric control slide rail 3 and the electric control tripod 1, the slider 10 at the bottom of the adapter rod 2 is slidably connected to the first chute 9 at the top of the control box 11, and then the screws are tightened to make the first locking block 16 tightly abut against the slider 10, thereby fixing the adapter rod 2. Then, the sliding seat 19 at the bottom of the inner hub 33 is slidably connected to the second chute 18 of the support 15 at the top of the adapter rod 2, and then the screws are tightened to make the second locking block 20 tightly abut against the sliding seat 19, thereby fixing the double variable stroke electric control slide rail 3 and completing the assembly.

[0027] After assembling the double variable stroke electric control slide rail 3 and the electric control tripod 1, when the drive 36 drives the synchronous belt 35 at one end of the track 31 to move forward and pulls the outer hub 32 towards the drive 36, the RCS tester 4 moves towards the drive 36 along with the outer hub 32. Since the inner hub 33 is fixed, the synchronous belt 35 at the other end of the track 31 will pull the track 31 and the outer hub 32 to move synchronously and in the same direction; when the drive 36 drives the synchronous belt 35 at one end of the track 31 to move in the reverse direction, since the inner hub 33 is fixed, the track 31 will be pushed and the drive 36 will move towards the inner hub 33, and the synchronous belt 35 at the other end of the track 31 will pull the outer hub 32 and the track 31 to move synchronously and in the same direction. During the whole moving process, since the outer hub 32 and the track 31 are always moving synchronously and in the same direction, the moving stroke of the outer hub 32 is the moving distance of the outer hub 32 relative to the track 31 plus the moving distance of the track 31 itself. When the outer hub 32 moves from one end of the track 31 to the other end of the track 31, the moving stroke of the outer hub 32 is twice the length of the track 31, that is, the double track 31 length stroke of the RCS tester 4 is realized. In this way, on the basis of ensuring that the moving stroke of the RCS tester 4 remains unchanged, the length of the track 31 can be shortened, and thus the overall volume of the test device can be reduced, making the test device suitable for small-size test scenarios.

[0028] As Figure 2 ,Figure 3 As shown, the electric control tripod 1 further includes an auxiliary support frame, and the auxiliary support frame includes a support base 23, a connection block 24, and a telescopic rod 25. There are three telescopic rods 25, and the three telescopic rods 25 correspond to the three electric control telescopic legs 12 one by one. A support base 23 is rotatably installed at the bottom of the electric control telescopic leg 12. One ends of the three telescopic rods 25 are rotatably connected to the connection block 24, and the other ends of the three telescopic rods 25 are rotatably connected to the support base 23 at the bottom of the corresponding electric control telescopic leg 12. When the three electric control telescopic legs 12 are retracted, the three telescopic rods 25 can automatically contract and retract together; after the three electric control telescopic legs 12 are deployed, the three telescopic rods 25 are immediately deployed. After the support wheels 14 are received, the electric control telescopic legs 12 are supported by the support base 23. The three telescopic rods 25 and the connection block 24 are used to provide auxiliary support for the electric control tripod 1, further ensuring the support stability.

[0029] The rotational connection between the above-mentioned structures can be realized by means of shaft connection. In the present invention, the electric control tripod 1, the adapter rod 2, the double variable stroke electric control slide rail 3, the RCS tester 4, and the monitoring display screen 5 are detachably assembled, and the disassembly and assembly are convenient, so that it is convenient to carry after disassembly, which is beneficial to improving work efficiency.
