An air outlet nozzle 9 is provided with a pressure reducing valve, and a connecting pipe 10 connected with the main gas cylinder 7 is provided on the pressure reducing valve. The main gas cylinder 7 and the auxiliary gas cylinder 8 can be considered to be in a connected state. Through the setting of the pressure reducing valve, when the pressure inside the auxiliary gas cylinder 8 is reduced, the pressure inside the main gas cylinder 7 is automatically filled into the auxiliary gas cylinder 8. The air outlet nozzle 9 is provided with a solenoid valve located on one side of the pressure reducing valve, and an air outlet pipe 11 connected with the air inlet nozzle 6 is fixed on the solenoid valve. A cable 12 is provided on the solenoid valve, and a control box 13 is provided at one end of the cable 12 away from the solenoid valve. Through the control box 13, the placement box 2 and the main gas cylinder 7, the inspection personnel only need to operate on the control box 13. After the solenoid valve is turned on, the gas inside the auxiliary gas cylinder 8 enters the inside of the launch tube 3 through the air outlet pipe 11, and the target inside the launch tube 3 is ejected under the push of the gas;

[0028] Taking into account that it is troublesome to manually lock the placement box 2, a rotating hole is provided on the two support arms 1, and a rotating shaft 14 is fixed in the middle of the two side walls of the placement box 2. The two rotating shafts 14 rotate coaxially in the corresponding rotating holes. A limiting disk 15 is fixed on the two side walls of the placement box 2, and the limiting disk 15 includes a full circle portion 16 and a semicircular portion 17. The two full circle portions 16 are coaxially arranged with the corresponding rotating shaft 14, respectively. A plurality of circumferentially uniformly distributed limiting blocks 18 are fixed at the outer edge of the semicircular portion 17. A strong electromagnet 19 is fixed on one side of the two support arms 1. A vertical rectangular groove 20 is provided on the support arm 1. A card block 21 that slides up and down is arranged inside the rectangular groove 20. The card block 21 is clamped between two adjacent limiting blocks 18. Two pairs of The positioning block 22 is distributed, and the positioning block 22 is located directly below the powerful electromagnet 19. An adsorption plate 23 is fixed on one side of the card block 21 close to the powerful electromagnet 19. The adsorption plate 23 is made of metal. Positioning rods 24 that penetrate the positioning block 22 are fixed on both sides of the bottom of the adsorption plate 23. The adsorption plate 23 is connected to the positioning block 22 through a spring. In a normal state, the powerful electromagnet 19 is not energized, and the card block 21 is inserted between two adjacent limit blocks 18 under the action of the spring. Through the settings of the powerful electromagnet 19, the rectangular groove 20 and the card block 21, when it is necessary to adjust the angle of the placement box 2, the powerful electromagnet 19 is energized, and the adsorption plate 23 contacts with the powerful electromagnet 19 under the action of strong magnetic force, and the card block 21 is disengaged from the limit block 18. Compared with the manual adjustment method, this method is more convenient.

[0029] refer to Figure 6 As shown, considering that it is troublesome to rotate the placement box 2 manually, a transmission gear 25 is coaxially fixed on one of the rotating shafts 14, and a motor 26 located above the transmission gear 25 is fixed on the support arm 1. The motor 26 is a reduction motor 26 without a self-locking function. A transmission gear 27 is coaxially fixed on the output end of the motor 26, and the transmission gear 27 is meshed with the transmission gear 25. The motor 26 is electrically connected to the control box 13. Through the settings of the motor 26, the transmission gear 25 and the transmission gear 27, when the placement box 2 is adjusted, the motor 26 and the strong electromagnet 19 are energized at the same time. After the clamping block 21 and the limit block 18 are disengaged from the limit, the rotating shaft 14 rotates driven by the motor 26 and other components. The inspection personnel can directly adjust the inclination angle of the placement box 2 by controlling the running time of the motor 26. After the adjustment of the placement box 2 is completed, the strong electromagnet 19 is first powered off, and the clamping block 21 is re-engaged with the limit block 18 under the action of the spring to generate a limit. After the placement box 2 no longer rotates, the motor 26 is powered off.

[0030] refer to Figure 5As shown, considering that there is a short-term increase in contact stress between the limit block 18 and the block 21 during the process of the powerful electromagnet 19 and the motor 26 being energized at the same time, the limit block 18 includes a tapered portion 28 and a vertical portion 29. The tapered portion 28 is used to guide the block 21. During the process of reinserting the block 21 between the two limit blocks 18, the motor 26 still drives the rotating shaft 14 to rotate until the block 21 and the limit block 18 are limited. Tapered blocks 30 are fixed on both sides of the vertical portion 29. The bottom of the block 21 is a tapered setting. Through the settings of the tapered portion 28 and the tapered block 30, the contact mode between the tapered block 30 and the side of the block 21 is line contact, and the friction force is small. Even if there is a short-term increase in contact stress between the limit block 18 and the block 21, the block 21 will still move upward rapidly under the action of the powerful electromagnet 19.

[0031] refer to Figure 3 As shown, considering that the launch tube 3 is placed inside the placement box 2, it may shake as the placement box 2 tilts, a U-shaped groove 31 is provided at the end of the placement box 2 away from the end cover 4, and the air inlet nozzle 6 is located inside the U-shaped groove 31. The placement box 2 is provided with a first fixing hole 32 located on both sides of the U-shaped groove 31, and the end cover 4 is provided with a second fixing hole 33 located directly above the launch tube 3. The internal threads of the first fixing hole 32 and the second fixing hole 33 are connected with bolts, and the launch tube 3 is fixed by the bolts.

[0032] refer to Figure 1 and Figure 2 As shown, in order to improve the stability of the launch tube 3 during launch detection, a mounting plate 34 is fixed to the bottom of the two support arms 1, and a mounting hole is opened on the mounting plate 34.

[0033] In order to facilitate the fixation of the main gas cylinder 7 and the placement box 2, a fixing plate is fixed to one side of the bottom of the placement box 2, and one end of the main gas cylinder 7 away from the gas outlet is fixedly connected to the fixing plate.

[0034] In order to prevent the main gas cylinder 7 and the auxiliary gas cylinder 8 from shaking, at least two cushion blocks are arranged between the main gas cylinder 7 and the placement box 2, and at least two cushion blocks are arranged between the main gas cylinder 7 and the auxiliary gas cylinder 8.

[0035] When the utility model is used:

[0036] First, the inspector only needs to operate on the control box 13. After the solenoid valve is turned on, the gas inside the auxiliary gas cylinder 8 enters the interior of the launch tube 3 through the gas outlet pipe 11, and the target inside the launch tube 3 is ejected under the push of the gas;

[0037] Then, when the angle of the placement box 2 needs to be adjusted, the motor 26 and the strong electromagnet 19 are energized at the same time, and the adsorption plate 23 contacts the strong electromagnet 19 under the action of the strong magnetic force. After the clamping block 21 and the limit block 18 are separated from the limit, the shaft 14 rotates driven by the motor 26 and other components, and the inspection personnel can directly adjust the tilt angle of the placement box 2 by controlling the running time of the motor 26;

[0038] Secondly, after the placement box 2 is adjusted, the powerful electromagnet 19 is powered off first, and the clamping block 21 is re-engaged with the limit block 18 under the action of the spring to limit the placement box 2. After the placement box 2 stops rotating, the motor 26 is powered off;

[0039] Finally, operate on the control box 13 again to test the launch tube 3.
