Description

Technical Field

[0001] This utility model belongs to the field of ultrasonic probe tool technology, and in particular relates to a special tool for disassembling a multi-channel ultrasonic probe. Background Technology

[0002] Multi-channel, multi-probe ultrasonic flow meters are widely used in the metering of natural gas transmitted from natural gas stations. During routine maintenance and repairs, scenarios involving cleaning or replacing probes frequently arise. Currently, probe disassembly primarily relies on socket wrenches. However, this method has several significant drawbacks. First, the entire disassembly process is extremely time-consuming, severely impacting maintenance efficiency.

[0003] Secondly, the operation is extremely labor-intensive, increasing labor costs and intensity. More importantly, the probe surface is easily scratched during operation. Once scratched, it will inevitably interfere with the propagation and reception of ultrasonic signals, leading to measurement errors and significantly reducing the accuracy of natural gas metering data. This could pose potential risks and economic losses to the operation and management of natural gas stations.

[0004] To address these issues, we provide a specialized tool for disassembling multi-channel ultrasonic probes. Utility Model Content

[0005] The purpose of this invention is to provide a special tool for disassembling a multi-channel ultrasonic probe. Through the action of the push rod, the device facilitates clear observation of the push rod and support, allowing it to precisely hold the probe tail while ensuring no damage to the cable connector at the probe tail. Furthermore, rotating the hexagonal nut pushes the push rod up and down, thereby pressing down the internal hexagonal nut at the probe tail, causing the probe to slowly rise. The probe tail can then extend into the through hole of the push rod, ensuring the safety and reliability of the probe disassembly process. This solves the problem that existing methods easily scratch the probe surface during operation. Once scratched, the ultrasonic signal propagation and reception inevitably interfere with each other, leading to measurement errors and significantly reducing the accuracy of natural gas metering data, potentially causing risks and economic losses to the operation and management of natural gas stations.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a special tool for disassembling a multi-channel ultrasonic probe, including a bracket, the surface of which has a through hole, and a push rod passing through the through hole;

[0007] A positioning rod is fixed at the bottom of the bracket;

[0008] The top of the push rod is the upper end of the push rod, the bottom of the push rod is the lower end of the push rod, and a hexagonal nut is fixed to the outer side of the upper end of the push rod;

[0009] The push rod has a hollow structure, and the inner wall of the lower end of the push rod is a hollow hexagonal shape;

Specific Implementation Example 1

[0040] Please see Figure 1-6This utility model is a special tool for disassembling a multi-channel ultrasonic probe, including a bracket 1. A through hole 2 is formed on the surface of the bracket 1, through which a push rod 3 passes. A positioning rod 4 is fixed to the bottom of the bracket 1. The top of the push rod 3 is the upper end 301, and the bottom is the lower end 302. A hexagonal nut 303 is fixed to the outer side of the upper end 301. The push rod 3 has a hollow structure, and the inner wall of the lower end 302 is a hollow hexagon. A positioning plate 5 is fixed to the end of the positioning rod 4 away from the bracket 1. A first threaded hole 6 is formed on the surface of the positioning plate 5. A mounting plate 7 is connected to the first threaded hole 6 by bolts. A second threaded hole 8 is formed on the surface of the mounting plate 7. A reinforcing plate 9 is fixed to the bottom of the mounting plate 7. This tool mainly consists of the bracket 1, the push rod 3, and the hexagonal nut 303. The bracket 1 is made of carbon steel. Its design aims to securely fix it to the flow meter housing; a through hole 2 is provided at the center of the bracket 1, through hole 2 allows the push rod 3 to pass freely, and there is a certain fitting clearance between the push rod 3 and the through hole 2. The push rod 3 is made of hollow brass material. The outer wall of the upper end 301 of the push rod has a transmission thread structure, and the outer wall of the lower end 302 of the push rod has a connection thread structure. The lower end 302 of the push rod is in the shape of a hollow hexagon. The size of the hexagon is precisely made according to the internal hexagonal nut of the ultrasonic probe. In addition, the diameter of the hollow part of the push rod 3 is larger than the tail diameter of the ultrasonic probe, and its depth is sufficient to provide good protection for the tail of the probe. The hexagonal nut 303 is fitted on the upper end 301 of the push rod. When the hexagonal nut 303 is rotated, the push rod 3 will move up and down accordingly.

[0041] Specifically, the upper end 301 of the push rod has a transmission thread 304 on its outer wall, and the lower end 302 of the push rod has a connecting thread 305 on its outer wall.

[0042] Furthermore, the reinforcing plate 9 has an arc-shaped structure, and several anti-slip strips 10 are fixed to the inner wall of the reinforcing plate 9.

[0043] The operation process of this embodiment is as follows: Before disassembling the ultrasonic probe, the flow meter branch needs to be vented and depressurized; after removing the probe fixing bolts, disconnect the probe wiring and wrap the cable connector with tape; properly place the disassembled components, then fix the positioning rod 4 on top of the probe, and clamp the reinforcing plate 9 on the other side of the branch, so that the reinforcing plate 9 and the positioning rod 4 clamp the branch, and turn the bolt into the first threaded hole 6 and the second threaded hole 8, so as to stably fix the bracket 1 on the outside of the flow meter. At this time, the center of the through hole 2 coincides with the center of the probe, and screw the hexagonal nut 303 onto the upper end 301 of the push rod, insert the push rod 3 through the through hole 2, so that the outer hexagon of the lower end 302 of the push rod is inserted into the inner hexagonal nut of the probe. At this time, the push rod 3 should be aligned and should not be tilted. Rotate the hexagonal nut 303 by hand so that the hexagonal nut 303 contacts the upper end face of the bracket 1. Then, use a wrench to rotate the hex nut 303. The hex nut 303 drives the push rod 3 to rotate, which in turn drives the internal hex nut used to fix the probe to rotate. The probe slowly moves along the axial direction, and the tail of the probe enters the through hole 3 of the push rod 3. By rotating continuously, the probe can be removed. During this process, care should be taken not to rotate the internal position and direction of the probe arbitrarily. Finally, clean the mounting hole of the probe to prevent foreign objects from entering the mounting hole. This device allows for clear observation of the push rod 3 and the bracket 1, enabling them to accurately hold the tail of the probe, while ensuring that the cable connector at the tail of the probe will not be damaged. By rotating the hex nut 303, the push rod 3 can be pushed up and down, thereby pressing down the internal hex nut at the tail of the probe, causing the probe to slowly rise, and the tail of the probe can be inserted into the through hole 2 of the push rod 3, thus ensuring the safety and reliability of the probe disassembly process. Specific Implementation Example 2

[0045] Please see Figure 4-6 Based on the first specific embodiment, a suction cup 11 is fixed on the surface of the positioning plate 5; a connecting pipe 12 is fixed to one end of the suction cup 11, an exhaust pipe 13 is fixed to one side of the connecting pipe 12, a first valve 14 is fixed to one end of the exhaust pipe 13; an air inlet pipe 15 is fixed to the end of the connecting pipe 12 away from the suction cup 11, a second valve 16 is fixed to one end of the air inlet pipe 15; and an air pump 17 is connected to the second valve 16 through a pipe.

[0046] Specifically, threaded tubes 18 are fixed on both sides of the bracket 1, and threaded rods 19 are connected to the threaded tubes 18 internally; a connecting rod 20 is fixed to one end of the threaded rod 19, a bearing 21 is fixed to one end of the connecting rod 20, and a stabilizing plate 22 is fixed to the outer ring of the bearing 21.

[0047] Furthermore, the stabilizing plate 22 has an arc-shaped structure and is attached to the outer wall of the push rod 3; a limit rod 23 is fixed on one side of the stabilizing plate 22, and limit holes 24 are opened on both sides of the bracket 1; the limit rod 23 passes through the limit hole 24.

[0048] The operation process of this embodiment is as follows: The suction cup 11 is fixed on the surface of the positioning plate 5 and connected to the exhaust pipe 13 and the air inlet pipe 15 through the connecting pipe 12. In use, first close the second valve 16 and open the first valve 14 to expel the air in the connecting pipe 12, so that the air pressure inside the suction cup 11 is lower than the external atmospheric pressure, thereby using atmospheric pressure to tightly adhere to the surface of the flow meter. Then close the first valve 14. When it is necessary to remove it, open the second valve 16, and the air pump 17 inflates the connecting pipe 12 through the air inlet pipe 15 to balance the air pressure inside the suction cup 11 with the external atmospheric pressure, so that the suction cup 11 can be detached. The suction cup 11, when fixing the positioning rod 4 to the outside of the flow meter, utilizes the suction force generated by atmospheric pressure to greatly enhance the stability of the positioning rod 4. Traditional methods of fixing the positioning rod 4 may cause it to loosen due to vibration, improper operation, or other factors, affecting the disassembly operation of the ultrasonic probe. The additional stabilizing effect provided by the suction cup 11 ensures that the positioning rod 4 remains stable during disassembly, thereby ensuring that the bracket 1 is stably fixed to the outside of the flow meter. This allows the push rod 3 to accurately disassemble the ultrasonic probe, improving the reliability and accuracy of the disassembly operation.

[0049] The stabilizing plate 22 is connected to the threaded tubes 18 on both sides of the bracket 1 via the threaded rod 19. The position of the stabilizing plate 22 can be adjusted by rotating the threaded rod 19. The stabilizing plate 22 has an arc-shaped structure and fits against the outer wall of the push rod 3. The limiting rod 23 on one side passes through the limiting holes 24 on both sides of the bracket 1. When the push rod 3 moves up and down in the through hole 2 of the bracket 1, the stabilizing plate 22 can restrict the radial movement of the push rod 3 to prevent the push rod 3 from shaking or deviating during rotation and up and down movement. At the same time, the bearing 21 ensures that the stabilizing plate 22 can restrict the push rod 3 without affecting the rotation adjustment of the threaded rod 19.
