[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-3 As shown, a gas sealing detection device for steel cylinder production includes a support frame 1, a water pressure testing machine body 2 is arranged at the center of the top of the support frame 1, and a fixing component 3 is arranged at the top of the support frame 1;

[0023] The fixing assembly 3 includes two movable plates 4. The top of the support frame 1 and the two sides of the water pressure testing machine body 2 are provided with sliding grooves matching the movable plates 4. The two movable plates 4 are slidably installed in the sliding grooves respectively, and the tops of the movable plates 4 are installed with lifting motors 5. The machine shafts of the two lifting motors 5 pass through the upper and lower ends of the movable plates 4 and are connected with screw rods 6. The outer ring of the screw rod 6 is threadedly connected to a fixing frame 7. A clamping block 10 is arranged on the side where the two fixing frames 7 are close to each other. A cylinder body 14 is arranged on the inner side of the two clamping blocks 10, and a conveyor belt 15 is arranged at the bottom of the cylinder body 14.

[0024] In this embodiment, the lower part of the cylinder body 14 is arranged in an arc shape, and an electric telescopic rod 8 is installed inside the two fixing frames 7, and a support block 9 is installed at the end of the push rod of the electric telescopic rod 8. The opposite sides of the two support blocks 9 are in contact with the lower outer wall of the cylinder body 14. The push rod of the electric telescopic rod 8 extends downward, driving the support block 9 to move downward to a suitable position, and the support block 9 plays a role in lifting the cylinder body 14.

[0025] In this embodiment, sliding rods 11 are slidably connected to the upper and lower ends of the fixed frame 7 near the front and rear ends, and the top ends of the sliding rods 11 are fixedly connected to the movable plate 4, and the bottom ends of the two sliding rods 11 are fixedly connected to the fixed plate 12. The provision of the sliding rods 11 facilitates the improvement of the stability of the movement of the fixed frame 7 and avoids the deviation of the fixed frame 7.

[0026] In this embodiment, the bottom end of the screw rod 6 is connected to the top end of the fixed plate 12, and bearings are provided at the connection between the shaft of the lifting motor 5 and the movable plate 4 and at the connection between the screw rod 6 and the fixed plate 12. The shaft of the lifting motor 5 is rotatably connected to the movable plate 4 through the bearing, and the screw rod 6 is rotatably connected to the fixed plate 12 through the bearing. The provided bearing can reduce rotational friction and prevent the fixed plate 12 from affecting the rotation of the screw rod 6.

[0027] In this embodiment, the clamp block 10 is set in a "V" shape, and the support block 9 is set in a "∠" shape. Anti-slip textures are provided at the contact points between the clamp block 10 and the support block 9 and the cylinder body 14. The anti-slip textures can increase the friction at the contact point and reduce the probability of slipping.

[0028] In this embodiment, driving cylinders 13 are installed on both sides of the support frame 1, and the ends of the driving push rods of the two driving cylinders 13 are respectively connected to the sides of the two movable plates 4 that are away from each other. The driving push rods of the two driving cylinders 13 are extended to drive the two movable plates 4 to move, thereby driving the clamping blocks 10 to approach each other, so as to facilitate the clamping of the cylinder body 14.

[0029] In this embodiment, a delivery pipe is provided at the bottom end of the water pressure testing machine body 2, and a sealing joint matching the cylinder body 14 is provided at the bottom end of the delivery pipe. Through the provided delivery pipe, the high-pressure water flow for testing can be conveniently delivered to the cylinder body 14.

[0030] It should be noted that the utility model is a gas seal detection device for steel cylinder production. When in use, first, when the steel cylinder body 14 moves to the bottom of the water pressure testing machine body 2, the conveyor belt 15 is closed, and the two driving cylinders 13 are opened. Because the driving push rod of the driving cylinder 13 is connected to the two movable plates 4, the movable plates 4 are slidably installed on the support frame 1, and the clamping blocks 10 are arranged on both sides of the steel cylinder body 14, and the clamping blocks 10 are connected to the movable plates 4 through various components, so that the driving push rods of the two driving cylinders 13 can be extended to drive the two movable plates 4 to move, thereby driving the clamping blocks 10 to approach each other to clamp the steel cylinder body 14;

[0031] When clamping, the push rod of the electric telescopic rod 8 can be controlled to extend downward according to the size of the cylinder body 14 in advance, driving the support block 9 to move downward to a suitable position. When the cylinder body 14 is clamped, the push rod of the electric telescopic rod 8 can be controlled to retract again, thereby driving the support block 9 to move upward and fit the bottom of the cylinder body 14. The support block 9 plays a role in lifting the cylinder body 14.

[0032] After the steel cylinder body 14 is fixed, the lifting motor 5 can be started as needed. Since the shaft of the lifting motor 5 is connected to the screw rod 6, and the screw rod 6 is threadedly connected to the fixing frame 7, the shaft of the lifting motor 5 can be rotated to drive the screw rod 6 to rotate, thereby driving the fixing frame 7 to rise or fall. The lifting motor 5 can be controlled to rotate forward as needed, thereby driving the fixing frame 7 to move upward, and the fixing frame 7 drives the fixed steel cylinder body 14 to move upward, thereby connecting the upper joint of the steel cylinder body 14 to the delivery pipe of the water pressure testing machine body 2, and then the high-pressure water flow for testing can be delivered to the steel cylinder body 14 according to the existing technology to perform airtightness detection;

[0033] After the test, the connection between the cylinder body 14 and the hydraulic testing machine body 2 can be released, and then the lifting motor 5 can be reversed according to the above steps, thereby driving the cylinder body 14 to fall onto the conveyor belt 15, and then the driving push rod of the driving cylinder 13 can be retracted by adjustment to drive the clamping block 10 away from the top of the conveyor belt 15, and then the conveyor belt 15 can be opened again to convey the tested cylinder body 14 out of the bottom of the hydraulic testing machine body 2, and the untested cylinder body 14 can be conveyed to the bottom of the hydraulic testing machine body 2 again, and the above steps can be repeated until all the cylinder bodies 14 are tested, and during the test process, records are made according to the qualified or unqualified conditions;

[0034] When testing cylinder bodies 14 of different sizes or heights, the initial heights and initial spacings of the two clamping blocks 10 can be adjusted according to the above steps, and the initial position of the support block 9 can be adjusted at the same time, so as to test cylinder bodies 14 of different sizes and heights and improve applicability.

Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model.
