Description

Technical Field

[0001] The present invention relates to the technical field of pipe fitting detection, and particularly to an airtightness detection device for non-standard pipe fittings. Background Art

[0002] Pipe fittings are a general term for components in a pipeline system that play roles such as connection, control, direction change, flow division, sealing, and support. Pipe fittings play a crucial role in the pipeline system. Through different forms and connection methods, they achieve the flexibility and functionality of the pipeline system. Non-standard pipe fittings refer to pipe fitting products that do not fully conform to national or industry standards, and they have certain personalized requirements and production requirements.

[0003] In order to ensure the airtightness and reliability of pipe fittings, airtightness detection needs to be carried out after the pipe fittings are processed. Usually, the airtightness of the connection parts of the pipe fittings is detected. Currently, when detecting the airtightness of pipe fittings, after one place of the pipe fitting is detected, the staff needs to manually change the detection position of the pipe fitting. And during the detection process of the pipe fitting, due to the certain weight of the pipe fitting itself, under the influence of its own weight during the detection process of the pipe fitting, the connection between the pipe fitting and the airtightness detection device will become loose, which results in poor airtightness of the device itself during the detection process and inaccurate detection results. Summary of the Invention

[0010] Preferably, a pressure sensor is installed at the bottom end of the inner wall of the second slot.

[0011] Preferably, stable sliding grooves are opened on both inner walls of the second slot. Stable sliding blocks are installed on one side of the sliding block facing the stable sliding grooves. The stable sliding blocks are slidably installed inside the stable sliding grooves.

[0012] Preferably, the sealing mechanism includes a first slot and an airbag. First slots are penetrated and opened at both ends of the fixed box. An airbag is embedded on the inner wall of the first slot.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] In the present invention, by setting the first driving wheel, the second driving wheel and the rotating roller, when the device performs airtightness detection on the pipe fitting through the fixed box, the abutment of the pipe fitting by the first driving wheel and the second driving wheel can increase the installation stability of the pipe fitting on the fixed box, and prevent the pipe fitting from loosening at the connection with the fixed box due to its own weight during the detection process, affecting the detection accuracy of the device;

[0018] After detecting a section of the pipe fitting, at this time, the length directions of the first driving wheel and the second driving wheel are both perpendicular to the length direction of the pipe fitting. By rotating the first driving wheel and the second driving wheel, the pipe fitting can be driven to move, so that the pipe fitting can complete automatic section change without manual operation by the staff, reducing the labor intensity of the staff and increasing the use convenience of the device;

[0019] The rotating roller abuts against the outer side of the pipe fitting. The length direction of the rotating roller is in a horizontal state with the length direction of the pipe fitting. The first driving wheel and the second driving wheel drive the pipe fitting to rotate. Under the abutting and squeezing of the rotating roller and the pipe fitting, the sliding block slides inside the second slotted opening and squeezes the pressure sensor. The pressure sensor transmits the measured pressure value to the background control system. During the rotation of the pipe fitting, by comparing the pressure values measured by multiple pressure sensors through the background control system, if the difference change of the pressure values measured by multiple pressure sensors exceeds the preset change interval value, it indicates that the outer circumference ratio of the pipe fitting does not meet the standard. Through this operation method, the automatic detection of the circumference ratio of the pipe fitting can be completed, increasing the use convenience of the device;

[0020] When the pipe fitting moves between two fixed boxes, at this time, the rotating roller rotates to a state where its length direction is perpendicular to the length direction of the pipe fitting, and the rotating roller abuts against the outer side of the pipe fitting. At this time, during the movement of the pipe fitting, by comparing the pressure values fed back by the pressure sensors through the background control system, if multiple pressure values exceed the preset pressure value change interval, it indicates that the outer side of this section of the pipe fitting is not straight. Through this operation method, the detection of the curvature rate of the outer side of the pipe fitting can be completed, increasing the diversity of the use functions of the device;

[0021] Drive the first movable block to move towards the pipe fitting through the first electric lifting rod until the rotating roller abuts against the outer side of the pipe fitting. Subsequently, detect the extrusion force between the rotating roller and the pipe fitting through the pressure sensor, and make the first movable block complete the extrusion of the pipe fitting at the preset pressure value. Then, observe the change on the outer side of the pipe fitting. Through this operation method, the anti-extrusion force detection of the pipe fitting can be completed.

By sliding the stabilizing slider 22 in the stabilizing groove 21, the sliding stability of the sliding block 17 in the second slot 20 can be increased.

[0040] As a technical optimization solution of the present invention, the sealing mechanism includes a first slot 9 and an airbag 10. The first slot 9 is penetrated at both ends of the fixing box 3, and the airbag 10 is embedded and installed on the inner wall of the first slot 9. When the airbag 10 is activated, the airbag 10 abuts against the outer wall of the pipe fitting, and seals the connection between the pipe fitting and the first slot 9, so that the space between the two fixing boxes 3 forms a closed space, so that the device can conveniently perform air tightness detection on the pipe fitting. The setting of the airbag 10 enables the device to measure pipe fittings of various specifications, which increases the convenience of using the device.

[0041] As a technical optimization solution of the present invention, the auxiliary mechanism includes a second movable block 14 and a third movable block 27. The mounting plate 1 is provided with the second movable block 14 at both ends of the fixed box 3. A first driving wheel 15 is embedded on the side of the second movable block 14 away from the mounting plate 1. The mounting plate 1 is provided with the third movable block 27 on both sides of the second movable block 14. The second driving wheels 28 are embedded on the sides of the two third movable blocks 27 close to each other. By means of the first driving wheel 15 and the second driving wheel 28 abutting against the pipe fitting, the pipe fitting can be driven to rotate and displace, and under the abutment of the first driving wheel 15 and the second driving wheel 28 on the pipe fitting, the pipe fitting can be fixed, increasing the stability of the pipe fitting when the device detects the pipe fitting.

[0042] As a technical optimization solution of the present invention, a first rotating motor 16 is embedded on the side of the second movable block 14 close to the mounting plate 1. The mounting end of the first rotating motor 16 is away from the second movable block 14. A second electric lifting rod 13 is provided on the side of the second movable block 14 close to the mounting plate 1. The mounting end of the second electric lifting rod 13 is connected to the mounting plate 1, and the lifting end of the second electric lifting rod 13 is connected to the mounting end of the first rotating motor 16. The first rotating motor 16 can drive the second movable block 14 to rotate, and the second electric lifting rod 13 can drive the second movable block 14 to lift.

[0043] As a technical optimization solution of the present invention, first chutes 11 are opened at the positions on both sides of the second movable block 14 at the tops of both ends of the bottom mounting plate 1. A first electric slider 12 is slidably mounted inside the first chute 11. A moving plate 5 is mounted on the top of the first electric slider 12. A second chute 25 is opened on the side of the moving plate 5 facing the second movable block 14. A rotating motor 29 is embedded on the side of the third movable block 27 close to the moving plate 5. The mounting end of the rotating motor 29 is away from the third movable block 27. The mounting end of the rotating motor 29 is connected to a second electric slider 26. The second electric slider 26 is slidably mounted inside the second chute 25. By the sliding of the first electric slider 12 in the first chute 11, the moving plate 5 can be driven to move. Combining with the sliding of the second electric slider 26 in the second chute 25, the third movable block 27 can be driven to move according to different usage requirements.

[0044] When the present invention is in use, the electrical devices used in the device are all powered by connecting to an external power supply through wires. The device controls the electrical devices in the device by setting up a control system. The air pressure sensor 6 and the pressure sensor 23 used in the device are both existing mature technologies, so no more elaboration will be made on them. The top of the air hole 2 is connected to a supercharging air pump through a conduit, and the connection between the conduit and the air hole 2 is controlled by a solenoid valve. Sealing rubber strips are provided at the abutting parts on the sides where the two fixing boxes 3 approach each other. The airbag 10 is connected to an air pump, and the air pump is an existing mature technology, so no more elaboration will be made on it.

[0045] When the airtightness of a pipe fitting needs to be detected, the device moves to the usage state as shown Figure 2 Subsequently, the staff passes the pipe fitting to be measured through the first slot 9 between the two fixing boxes 3, and the other end of the pipe fitting passes through the first slot 9 at the other end between the two fixing boxes 3. At this time, the section of the pipe fitting to be measured is located between the two fixing boxes 3. Then, the hydraulic rod 4 drives the upper mounting plate 1 to move downward, so that the two fixing boxes 3 abut against each other. The airbag 10 is activated, and the airbag 10 abuts against the outer wall of the pipe fitting to seal the connection between the pipe fitting and the first slot 9, so that the space between the two fixing boxes 3 forms a closed space. Then, by driving the second movable block 14 to extend through the second electric lifting rod 13 and moving the third movable block 27 through the moving plate 5, the second movable block 14 and the third movable block 27 move towards the pipe fitting until both the first driving wheel 15 and the second driving wheel 28 abut against the outside of the pipe fitting. By abutting the first driving wheel 15 and the second driving wheel 28 against the pipe fitting, the fixing of the pipe fitting can be completed, increasing the functional stability of the device. At this time, the space between the two fixing boxes 3 is pressurized by the supercharging air pump connected to the air hole 2. When the pressure increases to the preset pressure value, the solenoid valve at the air hole 2 is closed, so that there is a constant preset air pressure value between the two fixing boxes 3. Then, the air pressure between the two fixing boxes 3 is measured by the air pressure sensor 6, and the air pressure change between the two fixing boxes 3 is compared within a preset time period. If the air pressure value change exceeds the preset air pressure value change range, it means that the airtightness of the measured section of the pipe fitting does not meet the standard, otherwise it meets the standard. Through this measurement method, the airtightness detection of the pipe fitting can be completed.

[0046] After the position of a section of the pipe fitting is detected, at this time, the length directions of the first driving wheel 15 and the second driving wheel 28 are both perpendicular to the length direction of the pipe fitting. Subsequently, the airbag 10 deflates until the airbag 10 no longer abuts against the outer side of the pipe fitting. By rotating the first driving wheel 15 and the second driving wheel 28, the pipe fitting can be driven to move, so that the pipe fitting can complete automatic section change without manual operation by the staff, reducing the labor intensity of the staff and increasing the convenience of use of the device. Subsequently, the airtightness detection of another section of the pipe fitting can be completed according to the above operation steps.

[0047] During the process of changing the section for airtightness detection of the pipe fitting, by operating the first electric lifting rod 7 to drive the first movable block 8 to move up and down, the first movable block 8 moves towards the pipe fitting until the rotating roller 18 abuts against the outer side of the pipe fitting, and the first movable block 8 rotates so that the length direction of the rotating roller 18 is in a horizontal state with the length direction of the pipe fitting. The first driving wheel 15 and the second driving wheel 28 rotate until the length directions of the first driving wheel 15 and the second driving wheel 28 are in a horizontal state with the length direction of the pipe fitting. At this time, by rotating the first driving wheel 15 and the second driving wheel 28, the pipe fitting can be driven to rotate. During the rotation of the pipe fitting, the outer wall of the pipe fitting abuts against the rotating roller 18. Under the abutting and extrusion of the rotating roller 18 and the pipe fitting, the sliding block 17 slides inside the second slot 20 and squeezes the spring telescopic rod 24. The spring telescopic rod 24 squeezes the pressure sensor 23, and the pressure sensor 23 transmits the measured pressure value to the background control system. During the rotation of the pipe fitting, the background control system compares the pressure values measured by multiple pressure sensors 23. If the difference change of the pressure values measured by multiple pressure sensors 23 exceeds the preset change interval value, it means that the outer circumference ratio of the pipe fitting does not meet the standard. By this operation method, the automatic detection of the circumference ratio of the pipe fitting can be completed, increasing the convenience of use of the device.

[0048] When the pipe fitting moves between the two fixed boxes 3, at this time, the rotating roller 18 operates in a state where its length direction is perpendicular to the length direction of the pipe fitting, and the rotating roller 18 abuts against the outer side of the pipe fitting. At this time, during the movement of the pipe fitting, the background control system compares the pressure values fed back by the pressure sensor 23. If multiple pressure values exceed the preset pressure value change interval, it means that the outer side of this section of the pipe fitting is not straight. By this operation method, the detection of the curvature rate of the outer side of the pipe fitting can be completed, increasing the diversity of the use functions of the device.

[0049] Drive the first movable block 8 to move towards the pipe fitting through the first electric lifting rod 7 until the rotating roller 18 abuts against the outer side of the pipe fitting. Subsequently, detect the extrusion force between the rotating roller 18 and the pipe fitting through the pressure sensor 23, and make the first movable block 8 complete the extrusion of the pipe fitting under the preset pressure value. Then, observe the change on the outer side of the pipe fitting. Through this operation method, the anti-extrusion force detection of the pipe fitting can be completed.

[0050] As described above, only the preferred specific embodiments of the present invention are provided, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
