Description

Technical Field

[0001] This invention relates to the field of locomotive pipeline testing technology, specifically a quick-connect locomotive pipeline blockage precision positioning device. Background Technology

[0002] The locomotive's piping system is a core component that ensures the locomotive's critical functions such as braking and steering. During long-term use, the piping is prone to blockage due to the deposition of impurities in the medium, pipe aging and detachment, etc., which can lead to locomotive malfunction and safety hazards. Therefore, timely detection and location of pipe blockage is an important part of locomotive maintenance.

[0003] However, the existing devices have the following shortcomings during use: Existing methods for detecting pipe blockages typically require disassembling and inspecting the pipes. This method is not only time-consuming and labor-intensive, but may also cause secondary damage to the pipes during the inspection process. With the development of technology, ultrasonic waves, as a non-destructive testing technology, have been widely used in the field of pipe inspection. When ultrasonic waves propagate in a medium, they will produce reflection and refraction phenomena when they encounter interfaces between different media. By detecting changes in these signals, it is possible to determine whether there is a blockage inside the pipe and the location of the blockage. Secondly, pressure fluctuation analysis is also one of the important means of detecting pipe blockages. When a pipe is blocked, the flow of fluid in the pipe is obstructed, which will lead to changes and fluctuations in pressure. By monitoring the pressure changes in the pipe, the presence and severity of the blockage can be indirectly determined. However, using a single pressure wave or acoustic detection technology has the problems of large positioning errors, inability to determine the degree of blockage, and existing equipment is difficult to adapt to complex and narrow pipes, and the detection process is cumbersome and time-consuming.

[0004] Therefore, we propose a quick-connect locomotive pipeline blockage precision positioning device to solve the problems mentioned above. Summary of the Invention

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, through the setting of a quick-connect ultrasonic pressure pipeline positioning and quantification mechanism, utilizes a portable control host with a built-in microcontroller, central control motherboard, and data acquisition module. The connector has a built-in signal preprocessing circuit board, which can filter and amplify the raw signals collected by the high-frequency ultrasonic sensor and the high-precision pressure sensor. The data acquisition module receives the preprocessed signal, and the central control motherboard and microcontroller run a composite detection algorithm to complete data analysis. Simultaneously, according to the pipeline path to be detected, a matching quick-connect pipeline connector is selected to quickly connect with the locomotive pipeline, completing the detection without disassembling the pipeline. By integrating the detection logic of the two sensors, it can accurately locate the blockage location through the ultrasonic propagation characteristics and quantify the degree of blockage through pressure fluctuation analysis. This solves the problems of existing pipeline blockage detection methods, which usually require pipeline disassembly and inspection, which is time-consuming and laborious, and may cause secondary damage to the pipeline during the detection process. It also addresses the issues of large positioning errors and inability to determine the degree of blockage when using a single pressure wave or acoustic detection technology, as well as the problems of existing equipment being difficult to adapt to complex and narrow pipelines and having a cumbersome and time-consuming detection process.

[0017] 2. This invention, through the setting of an expansion and stabilizing mechanism, allows the rotation of the first rotating cap to drive the worm gear to mesh with the worm wheel, thereby rotating the bidirectional lead screw and causing the two expansion plates to unfold synchronously. The worm gear and worm wheel have self-locking characteristics, preventing the expansion plates from moving due to external forces or vibrations after unfolding, ensuring stable support. This effectively increases the support area at the bottom of the portable control unit, and the anti-slip pad further enhances placement stability. The cooperation between the guide rod and the moving seat ensures the smooth movement of the expansion plates. The support plate's support for the worm gear improves the transmission stability of the mechanism, allowing operators to clearly observe the data on the display screen and preventing the main unit from tipping over, thus further improving testing efficiency.

[0018] 3. This invention, through the setting of a side-mounted quick-release storage mechanism, allows the second wedge block of the quick-connect ultrasonic pressure pipeline positioning and quantification mechanism to be inserted into the mounting base slot. The second wedge block presses against the two first wedge blocks, compressing the return spring. After the second wedge block is fully inserted, the return spring's elastic force drives the two first wedge blocks into the two slots, quickly completing a stable locking installation. Rotating the second rotating cap drives the gear to drive the rack and pinion linkage rod, allowing the first wedge block to disengage from the slot for quick disassembly. The side-mounted design saves storage space, and the cooperation between the limiting block and the limiting slot further ensures connection stability, simplifies the disassembly and assembly process of the detection structure and portable control host, and facilitates the overall storage and carrying of the equipment.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] like Figures 1-10 As shown, the present invention provides a technical solution: a quick-connect locomotive pipeline blockage precision positioning device, including a portable control host 1, a quick-connect ultrasonic pressure pipeline positioning and quantification mechanism 2 is provided on one side of the portable control host 1, a side-mounted quick-release storage mechanism 4 is provided on the other side of the portable control host 1, and an expansion and stabilization mechanism 3 is provided at the bottom of the portable control host 1. The quick-connect ultrasonic pressure tubing positioning and quantification mechanism 2 includes a connector 201 and an anti-interference signal transmission line 202. A detection housing 203 is fixedly connected to one side of the connector 201. A connecting pipe 204 is fixedly connected to one end of the detection housing 203. A connecting thread 205 is provided on the outer surface of one end of the connecting pipe 204. A quick-connect tubing connector 206 is installed on the outer surface of one end of the connecting pipe 204 via the connecting thread 205. A high-frequency ultrasonic sensor 207 and a high-precision pressure sensor 208 are installed on the inner surface of the detection housing 203. By integrating the high-frequency ultrasonic sensor 207 and the high-precision pressure sensor 208 within the detection housing 203, dual-dimensional raw data support is provided for the composite detection algorithm. This achieves precise location of the blockage by utilizing the propagation characteristics of ultrasonic waves and quantifies the degree of blockage through pressure fluctuation signals. This design addresses the shortcomings of single-sensor technology, such as large positioning errors and inability to determine the degree of blockage. The connecting threads 205 on the outer surface of the connecting pipe 204 allow for flexible disassembly and replacement of the quick-connect pipe joint 206, enabling rapid adaptation to different pipe diameters of the locomotive under test. The quick-connect pipe joint 206 also features a built-in sealing gasket, achieving a tight fit with the locomotive pipe interface without the need for additional sealing components. This improves installation convenience and enhances sealing reliability, effectively preventing leakage of the medium within the pipe from affecting the accuracy of the test data. It also avoids the risk of leakage due to missing or improperly installed seals, and reduces direct friction between the joint and the pipe interface, lowering the probability of secondary damage to the pipe. The anti-interference signal transmission line 202 reduces interference from the locomotive's electromagnetic environment on the test signal, ensuring stable transmission of the original data and providing a precise foundation for subsequent data analysis.

[0023] like Figure 1 , Figure 7 and Figure 8 As shown, the expansion and stabilization mechanism 3 includes a base 301 fixedly connected to the bottom of the portable control host 1. A bidirectional lead screw 302 is rotatably connected to the inner side of the base 301. Two guide rods 303 are fixedly connected to the inner side of the base 301. Two movable seats 304 are threadedly installed on the outer surfaces of the bidirectional lead screw 302 and the two guide rods 303. Through the arrangement of the bidirectional lead screw 302 and the two guide rods 303, the rotation of the bidirectional lead screw 302 can drive the two movable seats 304 to move synchronously in opposite directions, thereby realizing the expansion plate 30 The smooth unfolding and retraction of the 5-axis, the guide rod 303 restricts the rotational freedom of the movable seat 304, and avoids deviation, jamming or tilting during the movement, ensuring the smooth operation of the expansion and stabilization mechanism 3; the structure realizes the adjustable support area through mechanical transmission, eliminating the need to manually drag the expansion plate 305, making operation more labor-saving, and the high precision of the threaded and sliding fit between the movable seat 304 and the bidirectional lead screw 302 and guide rod 303 ensures that the expansion plate 305 unfolds at a uniform distance, improving the stability of the portable control host 1.

[0024] like Figure 1 , Figure 7 and Figure 8 As shown, two expansion plates 305 are fixedly connected to the bottom of the two movable seats 304. A worm gear 306 is rotatably connected to the inner side of the base 301. A worm wheel 307 is fixedly sleeved on the outer surface of the bidirectional lead screw 302. The worm gear 306 and the worm wheel 307 are meshed and connected. Through the meshing transmission of the worm gear 306 and the worm wheel 307, it has the advantages of stable transmission ratio and low operating noise. It can smoothly transmit the rotational force of the first rotating cap 308 to the bidirectional lead screw 302, driving the expansion plate 305 to slowly and evenly unfold. At the same time, the worm wheel 307 and the worm gear 306 have self-locking characteristics, which can firmly lock the unfolded position of the expansion plate 305, preventing the expansion plate 305 from moving or retracting on its own under the circumstances of vibration or external force contact at the locomotive maintenance site. This ensures that the portable control host 1 always maintains a stable support state and avoids affecting the detection operation or damaging the equipment due to the host tilting.

[0025] like Figure 3 , Figure 7 and Figure 8 As shown, a support plate 309 is fixedly connected to the top inner side of the base 301. One end of the worm gear 306 is rotatably connected to the support plate 309, and the other end of the worm gear 306 moves through the base 301 and is equipped with a first rotating cap 308. Two anti-slip pads 310 are installed at the bottom of the two expansion plates 305. By setting the two anti-slip pads 310, the coefficient of friction is increased, effectively preventing the portable control host 1 from sliding and tipping on the oily ground, and further enhancing the stability of the placement.

[0026] like Figure 1 , Figure 2 , Figure 9 and Figure 10 As shown, the side-mounted quick-release storage mechanism 4 includes a mounting base 401 fixedly connected to one side of the portable control host 1. A slot 402 is provided on one side of the mounting base 401. Two grooves 403 are provided inside the slot 402, and two first wedge blocks 404 are disposed within the two grooves 403. Two movable rods 405 are fixedly connected to one side of each of the two first wedge blocks 404. Two return springs 406 are sleeved on the outer surface of each movable rod 405. The slot 402 of the mounting base 401 provides a precise positioning channel for the second wedge blocks 407, facilitating quick alignment and insertion. The first wedge block 404 in the groove 403, together with the movable rod 405 and the return spring 406, forms an elastic engagement structure. During installation, the second wedge block 407 can automatically squeeze the first wedge block 404 through the wedge surface, thereby compressing the return spring 406. Pre-fixation can be completed without additional manual operation, simplifying the installation process. The return spring 406 provides a continuous elastic force to the first wedge block 404, ensuring that the first wedge block 404 and the slot 408 fit tightly after engagement, thus improving the stability of the connection between the quick-connect ultrasonic pressure pipeline positioning and quantification mechanism 2 and the side-mounted quick-release storage mechanism 4.

[0027] like Figure 1 , Figure 2 , Figure 9 and Figure 10 As shown, a second wedge block 407 is fixedly connected to one side of the connecting seat 201, which cooperates with the two first wedge blocks 404. The top and bottom of the second wedge block 407 have two slots 408, which are adapted to the two first wedge blocks 404. The wedge-shaped surfaces of the second wedge block 407 and the first wedge block 404 cooperate with each other, which plays a guiding role in installation. When the second wedge block 407 is inserted into the slot 402, it can smoothly squeeze the first wedge block 404 without precise alignment, reducing the difficulty of installation. The slots 408 at the top and bottom of the second wedge block 407 are precisely adapted to the first wedge block 404. After the return spring 406 drives the first wedge block 404 to squeeze into the slot 408, a mechanical limit lock is formed, which effectively prevents the quick-connect ultrasonic pressure pipeline positioning and quantification mechanism 2 from disengaging from the mounting seat 401. The engaging structure of the slots 408 and the first wedge block 404 is simple and compact. It achieves a stable connection without occupying too much space, making it easy to carry.

[0028] like Figure 1 , Figure 9 and Figure 10 As shown, one end of each of the two movable rods 405 passes through the two grooves 403 and the mounting base 401 and is fixedly connected to two connecting brackets 409. Two racks 410 are fixedly connected to one side of each connecting bracket 409. A rotating shaft 411 is rotatably connected to the top of the mounting base 401. A gear 412 is fixedly sleeved on the outer surface of the rotating shaft 411. The gear 412 meshes with the two racks 410. A second rotating cap 413 is installed at the top of the rotating shaft 411. Through the meshing transmission between the gear 412 and the two racks 410, rotating the second rotating cap 413 will drive the gear 412 to rotate. The movement of the racks 410 in turn drives the two racks 410 to move in opposite directions. The connecting frame 409 pulls the movable rod 405, causing the first wedge block 404 to simultaneously disengage from the slot 408. This eliminates the need to operate the two sides of the structure separately, simplifying the disassembly process of the quick-connect ultrasonic pressure pipeline positioning and quantification mechanism 2 and saving maintenance time. The connecting frame 409 firmly connects the racks 410 and the movable rod 405, ensuring efficient transmission of power and avoiding disassembly difficulties caused by jamming of a single movable rod 405. The second rotating cap 413 increases the contact area for applying force, allowing operators to easily rotate it without special tools, thus improving operational convenience.

[0029] like Figure 1 , Figure 9 and Figure 10As shown, four first limiting grooves 414 are provided on the inner side of the two grooves 403. Four first limiting blocks 415 are slidably connected in the four first limiting grooves 414. The four first limiting blocks 415 are fixedly connected to the two first wedge blocks 404. Two second limiting grooves 416 are provided on the top of the mounting base 401. Two second limiting blocks 417 are slidably connected in the two second limiting grooves 416. The tops of the two second limiting blocks 417 are fixedly connected to the two connecting brackets 409. Through the cooperation of the first limiting grooves 414 and the first limiting blocks 415, the first wedge is limited. The movement trajectory of the first wedge block 404 is designed to prevent it from shifting, tilting, or disengaging from the preset stroke within the groove 403, ensuring that the first wedge block 404 always moves axially and precisely engages or disengages from the slot 408. The cooperation between the second limiting groove 416 and the second limiting block 417 guides and limits the movement of the connecting frame 409 and the rack 410, preventing the rack 410 from meshing with the gear 412 and ensuring smooth operation of the transmission mechanism. The setting of the limiting structure effectively reduces component wear, extends the service life of the side-mounted quick-release storage mechanism 4, and improves the operational stability of the mechanism.

[0030] like Figure 1 , Figure 2 and Figure 6 As shown, a plug-in hole 210 is provided on one side of the portable control host 1, and a plug-in connector 211 is provided inside the plug-in hole 210. An anti-interference signal transmission line 202 is provided at one end of the plug-in connector 211. The end of the anti-interference signal transmission line 202 away from the plug-in connector 211 is connected to the connector 201. A handle 209 is installed on one side of the connector 201. The detection shell 203 has a conical structure. Through the cooperation of the plug-in hole 210 and the plug-in connector 211, the anti-interference signal transmission line 202 and the portable control host 1 can be quickly plugged and unplugged. The handle 209 is... The operator is provided with a convenient grip to facilitate the handheld quick-connect ultrasonic pressure pipeline positioning and quantification mechanism 2 for pipeline docking and installation. The detection housing 203 adopts a conical structure and is made of stainless steel, which can focus the divergent sound waves emitted by the high-frequency ultrasonic sensor 207 into a directional beam, reduce the radial scattering of sound wave energy, improve the propagation efficiency of sound waves along the pipeline axis, enable sound waves to penetrate pipeline media over a longer distance, expand the detection coverage, and at the same time enhance the intensity of the reflected signal, making it easier for the high-frequency ultrasonic sensor 207 to capture the reflected waves of blockages.

[0031] like Figure 1 , Figure 2 and Figure 3As shown, the portable control host 1 has a display screen 5 on its front side, a power switch 6 and two data output interfaces 7 on one side, and a detachable audible and visual alarm device 8 on its top. A handle 9 is also mounted on the top of the portable control host 1. The display screen 5 visually presents the detected blockage location, blockage level, and other data, allowing operators to intuitively obtain core detection information without professional interpretation, thus lowering the barrier to entry. The power switch 6 enables quick start and stop control of the portable control host 1, and the data output interfaces 7 support the export and storage of detection data, facilitating subsequent archiving, analysis, and traceability of maintenance records. The detachable audible and visual alarm device 8 provides dual alerts of sound and light when critical anomalies such as severe blockages are detected, enabling operators to quickly detect emergency faults and take timely action. The handle 9 is ergonomically designed, allowing operators to easily carry the portable control host 1 around the maintenance site, improving the equipment's portability and adapting to the detection needs of various pipelines in locomotives.

[0032] The usage method and working principle of this device: During the adapter selection stage, according to the pipe diameter of the locomotive pipeline to be tested, the existing quick-connect pipe connector 206 of the quick-connect ultrasonic pressure pipeline positioning and quantification mechanism 2 is disassembled through the connecting thread 205, and a quick-connect pipe connector 206 of matching specifications is replaced (the connector has a built-in sealing gasket and no additional assembly is required) to ensure a sealed fit with the pipeline interface. During the placement and stabilization phase, the portable control host 1 is placed on a flat area of ​​the locomotive maintenance site. The first rotating cap 308 is rotated, and the worm gear 306 meshes with the worm wheel 307 to drive the bidirectional lead screw 302 to rotate. This causes the two moving seats 304 to unfold synchronously along the guide rod 303, increasing the bottom support area of ​​the portable control host 1. The anti-slip pad 310 at the bottom of the expansion plate 305 is in contact with the ground to ensure that the host is stable and does not shake. During the locomotive pipeline docking stage, hold the handle 209 and align the quick-connect pipeline connector 206 at one end of the test housing 203 with the locomotive pipeline interface, insert it directly and tighten it. The docking can be completed without disassembling the pipeline, thus avoiding media leakage. During the data acquisition and transmission phase, the equipment is started via the power switch 6 of the portable control host 1. Then, the detection mode (adaptable to different pipeline media types) is selected via the display screen 5 of the portable control host 1, and parameters such as detection range and sensitivity are set. After confirmation, the detection program is started. The high-frequency ultrasonic sensor 207 and the high-precision pressure sensor 208 synchronously collect the sound wave signal and pressure fluctuation signal in the pipeline. After being filtered and amplified by the signal preprocessing circuit board built into the connector 201, the signal is transmitted to the portable control host 1 through the anti-interference signal transmission line 202. The operator can observe the location of the blockage and the degree of blockage (mild / moderate / severe) in real time via the display screen 5. If severe blockage is detected, the audible and visual alarm device 8 will automatically trigger an audible and visual reminder. The operator can export the detection report through the data output interface 7 to provide a basis for maintenance. During the storage and organization phase, loosen the quick-connect pipe connector 206 and pull it out of the locomotive pipe interface to separate it from the pipe. Reverse the first rotating cap 308 to retract the expansion plate 305 back to its original position. Then, using the handle 209 on one side of the connecting seat 201 with the quick-connect pipe connector 206 facing downwards, align the second wedge block 407 with the mounting base 401 slot 402 of the side-mounted quick-release storage mechanism 4 and insert it. Squeeze the first wedge block 404 to compress the return spring 406. After the second wedge block 407 is fully inserted, the return spring 406 will release. The first wedge 404 is inserted into the slot 408, completing the quick fixation of the quick-connect ultrasonic pressure tubing positioning and quantification mechanism 2. If it needs to be reused, the second rotating cap 413 can be rotated to drive the rack 410 through the gear 412, and the movable rod 405 can be pulled to disengage the first wedge 404 from the slot 408. Then the second wedge 407 can be pulled out from the slot 402. Finally, the power switch 6 is turned off, and the portable control host 1 is carried by the handle 9. The quick-connect ultrasonic pressure tubing positioning and quantification mechanism 2 and the portable control host 1 are stored together to complete the storage.
