[0024] This utility model provides, for example Figures 1-6 The ship-borne testing system shown is used for signal quality assessment of airborne communication equipment. It includes a test stand 1, which includes signal analysis instruments, power supply, etc. It tests VHF communication equipment, aviation satellite communication equipment, etc., mounted on ships, thereby realizing the signal quality assessment of airborne communication equipment. The test stand 1 and its working principle are common existing technologies, and will not be described in detail here.

[0025] To improve the ease of movement of the testing machine 1, casters 2 are provided at the four corners of the bottom of the testing machine 1. The casters 2 include a frame 201 and a wheel 202. The frame 201 is rotatably mounted on the bottom of the testing machine 1, and the wheel 202 is rotatably connected to the frame 201, which facilitates the movement of the testing machine 1.

[0026] Considering the susceptibility of ships to turbulence, a through hole 7 is provided at the top of the frame 201 to improve the stability of the test platform 1. The through hole 7 extends through the bottom of the test platform 1. An elastic telescopic rod 8 is slidably installed inside the through hole 7, and a pressure strip 6 is fixedly connected to the bottom end of the elastic telescopic rod 8. The pressure strip 6 engages with the wheel 202 through a pressing mechanism. When the elastic telescopic rod 8 moves downwards inside the through hole 7, it causes the pressure strip 6 to move downwards synchronously, thus pressing and limiting the wheel 202 to achieve a braking effect.

[0027] A base plate 12 is provided below the test machine 1, and the base plate 12 and the pressure strip 6 move up and down synchronously using a moving component. The moving component includes a square frame 9, a circular groove 10, a sliding column 11, and a horizontal plate 15. The square frame 9 is slidably disposed inside the test machine 1, and the top end of the elastic telescopic rod 8 is rotatably connected to the square frame 9. The circular groove 10 is opened at the bottom of the test machine 1, the sliding column 11 is slidably disposed inside the circular groove 10, the horizontal plate 15 is fixedly connected to the top end of the sliding column 11, the horizontal plate 15 is fixedly connected to the square frame 9, and the base plate 12 is fixedly connected to the bottom end of the sliding column 11.

[0028] Since the top of the elastic telescopic rod 8 is rotatably connected to the frame 9, the pressure strip 6 and the elastic telescopic rod 8 can rotate synchronously with the frame 201.

[0029] In addition, the test machine 1 is equipped with control components, including electric push rods, etc. The telescopic end of the electric push rod is connected to the horizontal plate 15 and is used to drive the frame 9 and the like to move up and down through the horizontal plate 15. The control components are common existing technologies and will not be described in detail here.

[0030] In actual use, when the test platform 1 moves to the designated position, the control components drive the horizontal plate 15 and the square frame 9 to move downward. The horizontal plate 15 drives the base plate 12 to move downward through the sliding column 11. The base plate 12 contacts the ground, expanding the support area and improving the stability of use. At the same time, the square frame 9 drives the elastic telescopic rod 8 to move downward inside the through hole 7, and the pressure strip 6 moves downward synchronously. The pressure strip 6 squeezes and limits the wheel body 202 to achieve the braking effect.

[0031] Furthermore, anti-slip pads or similar materials can be installed on the lower surface of the base plate 12 to achieve an anti-slip effect.

[0032] This utility model incorporates a swivel wheel 2, a pressure strip 6, and a moving component. The pressure strip 6 compresses and limits the wheel body 202, achieving a braking effect. Simultaneously, the base plate 12 contacts the ground, expanding the support area and improving stability during use. This ensures the stability of the ship-mounted testing system and enhances the efficiency of signal quality assessment for airborne communication equipment.

[0033] A vertical cylinder 3 is fixedly connected to the frame 201. A round rod 4 is slidably installed inside the vertical cylinder 3. A disc 5 is fixedly connected to the bottom end of the round rod 4. A sliding channel for a pressure strip 6 to pass through is opened on the vertical cylinder 3. The pressure strip 6 is fixedly connected to the top of the round rod 4. When the pressure strip 6 moves downward, it will drive the round rod 4 to move downward synchronously. The disc 5 contacts the ground. The four discs 5 are distributed at the four corners below the testing machine platform 1 and cooperate with the base plate 12 to further improve the stability of use.

[0034] The bottom of the base plate 12 has a groove 16, and a suction cup 13 is installed inside the groove 16. The sliding column 11 has a suction channel 14 inside, which is connected to the suction cup 13. The control components inside the test machine 1 also include a pump body, a solenoid valve, etc. The pump body is connected to the suction channel 14 and works in conjunction with it to suction the suction cup 13.

[0035] When the base plate 12 comes into contact with the ground, the suction cup 13 adheres to the ship's ground. The suction channel 14 draws suction from the inside of the suction cup 13, thereby adsorbing and fixing the base plate 12 to the ship's ground and maintaining this adsorption state to ensure the stability of the test machine 1.

[0036] If it is necessary to move the test machine 1 to another location on the ship, release the suction cup 13 to fix it, and move the frame 9 and other structures upwards. The disc 5 and the base plate 12 will detach from the ship's ground and move by means of the casters 2.
