Description

Technical Field

[0001] The invention relates to the technical field of assembly and maintenance, and in particular to an intelligent assembly and inspection vehicle for high-speed train sets. Background Art

[0002] When a high-speed train passes through a station, it is often necessary to quickly inspect the bolted connections of key components such as bogies and brake systems to ensure the timeliness and safety of subsequent operation. However, due to the narrow space at the bottom of the vehicle, which is densely packed with key components such as bogies and brake systems, maintenance personnel are often restricted in their movements in such a small space, making inspection difficult. For example, when inspecting the bolts on the bogie, maintenance personnel often have to use extremely awkward postures to barely approach the bolts, which makes the inspection work not only difficult to operate, but also difficult to ensure the accuracy of the inspection.

[0003] At the same time, due to the cramped space, maintenance personnel have difficulty finding the right point of force. When using conventional tools for tightening operations, they often cannot exert force normally due to space obstacles, resulting in the bolt tightening torque being difficult to meet standard requirements, posing a safety hazard to the operation of the train. In addition, during the maintenance process, bolts in different parts may require tools of different specifications for inspection and tightening. However, the narrow space makes tool replacement extremely inconvenient, greatly reducing maintenance efficiency.

[0040] Unless otherwise defined, all technical terms and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0041] See also Figure 1 , which shows a structural schematic diagram of a high-speed EMU intelligent assembly and inspection work vehicle provided in an embodiment of the present application, wherein the work vehicle includes a mounting base 100, a first drive mechanism 200, a second drive mechanism 300, a camera mechanism 400, a screwing motor 510, a screwing adjustment mechanism 520 and a control console.

[0042] Specifically, the four sides of the mounting base 100 extend upward to form side walls, and the first driving mechanism 200 is disposed on the side walls of the mounting base 100 to drive the mounting base 100 to move so as to approach or move away from the bottom of the high-speed train. The second driving mechanism 300 is installed above the mounting base 100 and moves along with the movement of the mounting base 100 driven by the first driving mechanism 200.

[0043] The second driving mechanism 300 is provided with a camera mechanism 400 and a screwing motor 510. The second driving mechanism 300 is electrically connected to the control console, so as to drive the camera mechanism 400 and the screwing motor 510 to move under the control of the control console to approach the target to be detected. Preferably, the camera mechanism 400 can be a macro camera mechanism 400, a panoramic camera mechanism 400 or a wireless camera mechanism 400, so as to capture the image information of the bolted joints of key components such as the bottom rotation and the braking system in real time. The camera mechanism 400 is electrically connected to the control console, and the captured image information is sent to the control console to make a preliminary judgment for the subsequent analysis of whether the bolted joints need to be repaired. The screwing motor 510 is arranged on one side of the camera mechanism 400, and the output end of the screwing motor 510 is connected to the screwing adjustment mechanism 520 for driving, and receives the control console command through the electrical circuit, so as to drive the screwing adjustment mechanism 520 to complete the screwing of the bolted joints.

[0044] The console is used to receive image information from the camera mechanism 400. Preferably, an advanced intelligent system is set inside the console. When the camera mechanism 400 transmits the captured image information of the bolt connector to the console, the intelligent system immediately performs a deep analysis of the image, and intelligently analyzes several possible types of bolt connectors based on the preset image recognition algorithm and the bolt connector database. For example, by identifying the characteristics of the bolt head shape, thread spacing, size, etc., the standard model to which it belongs can be determined. The operator can intuitively view these analysis results on the display screen of the console, and combine them with the image to determine whether the bolt connector needs to be repaired. For example, if obvious wear and cracks are found on the surface of the bolt, or abnormal conditions such as deformation of the thread are found, it can be determined that maintenance is required. Once it is determined that maintenance is necessary, the operator can select one of the possible types analyzed by the intelligent system, and the system will automatically match the appropriate tool according to the selected type; in addition, when the type of bolt connector selected by the intelligent system is not suitable for this maintenance, the operator can input the correct screwing tool into the console to match the correct detection tool. After the bolt connector is selected, the console controls the screw adjustment mechanism 520 to adjust a screw interface that is suitable for the bolt connector based on the matched tool.

[0045] The use process of the high-speed train intelligent assembly and inspection vehicle provided in this application is as follows:

[0046] First, the operator pushes the work vehicle to the bottom of the high-speed EMU, and starts the first drive mechanism 200 through the console so that the work vehicle moves along the bottom of the vehicle to the area where the bolted connector to be detected is located. After arriving at the target area, the operator turns on the second drive mechanism 300 and pushes the camera mechanism 400 to gradually approach the bolted connector to be detected. The camera mechanism 400 quickly captures the image information of the bolt and transmits it to the console in real time. The intelligent system in the console analyzes the image and quickly gives a variety of possible types of bolted connectors with the help of built-in algorithms and databases. Based on these analysis results and intuitive image display, the operator accurately determines whether the bolt needs to be repaired. When it is determined that maintenance is required, the console will control the screwing adjustment mechanism 520, switch to the appropriate screwing interface, and start the screwing motor 510 to drive the screwing adjustment mechanism 520 to screw the bolted connector. During this process, the console will record various key parameters in real time, such as screwing torque, angle, and tool model and other usage parameters. After the inspection of the bolt is completed, the second drive mechanism 300 resets the camera mechanism 400 and the screwing motor 510. The first drive mechanism 200 operates again to drive the mounting base 100 to move to the next target position, and the cycle continues until all bolts are inspected and inspected.

[0047] The beneficial effects of the intelligent assembly and inspection vehicle for high-speed train sets provided by the present application are as follows:

[0048] The first driving mechanism 200 drives the mounting base 100 to move under the vehicle, and the second driving mechanism 300 drives the camera mechanism 400 and the screwing motor 510 to approach the bolted connector, replacing the manual inspection operation. The work vehicle can freely shuttle through the complex area under the vehicle that is difficult for manual inspection to penetrate by relying on the flexible mobile structure. The camera mechanism 400 can accurately capture the image information of the bolted connector, which can avoid the artificial visual error caused by the complex environment under the vehicle. At the same time, in the screwing link, the screwing motor 510 cooperates with the screwing adjustment mechanism 520 to automatically screw according to the instruction without manual operation, avoiding the disadvantage of the difficulty of the inspection personnel caused by the complex environment under the vehicle, greatly reducing the labor intensity of the manual labor, improving the inspection accuracy, and saving a lot of labor costs. In addition, the camera system and the screwing adjustment mechanism 520 can quickly respond to bolted connectors of different sizes, quickly switch working modes, significantly speed up the maintenance efficiency, and comprehensively improve the quality and speed of the maintenance work of the high-speed EMU, so that when facing the maintenance task of a large number of bolts, the overall maintenance efficiency is significantly improved, ensuring that the high-speed EMU can be put into operation faster.

[0049] Preferably, if Figure 4 As shown, the first driving mechanism 200 includes two track transmission mechanisms 210, and the two track transmission mechanisms 210 are respectively arranged on opposite sides of the mounting base 100, and the track transmission mechanism 210 includes a first motor, a plurality of rollers 211 and a track 212; the first motor is respectively driven and connected with the plurality of rollers 211 in a one-to-one correspondence, and the plurality of rollers 211 are arranged in sequence and spaced apart in the horizontal direction, and the track 212 is wound around the plurality of rollers 211, and the plurality of rollers 211 are driven and connected with the track 212 in sequence.

[0050] Specifically, the crawlers 212 on both sides can more effectively adapt to the vehicle bottom areas of different shapes and different surface conditions. Even if encountering obstacles such as potholes and bumps, it can still travel smoothly, avoiding the working vehicle from affecting the detection and maintenance work due to imbalance. At the same time, the crawlers 212 can increase the contact area between the ground and the bottom of the vehicle, disperse the weight of the working vehicle, reduce the pressure on the local area of ​​the bottom of the vehicle, and reduce the impact of vibration and bumps on the detection and maintenance accuracy during the operation, further improving the accuracy and reliability of the overall operation. The crawlers 212 on both sides of the working vehicle are driven by independent first motors. When the direction needs to be adjusted, it can be achieved by controlling the different speeds of the crawlers 212 on both sides. For example, if you want to turn to the left, you can reduce the speed of the left crawler 212, while maintaining or appropriately increasing the speed of the right crawler 212, and use the speed difference of the crawlers 212 on both sides to make the working vehicle turn to the left smoothly.

[0051] like Figure 2 and Figure 3 As shown, the second driving mechanism 300 includes a first mounting frame 310 , a second motor 320 , a first swing arm 330 , a third motor 340 , a second swing arm 350 , a fourth motor 360 and a second mounting frame 370 .

[0052] Specifically, the first mounting frame 310 is arranged on the mounting base 100, and a first mounting groove 311 is opened on the first mounting frame 310, the second motor 320 is arranged in the first mounting groove 311, the output end of the second motor 320 is drivingly connected to one end of the first swing arm 330, and a second mounting groove 331 is opened at the other end of the first swing arm 330, the third motor 340 is arranged in the second mounting groove 331, the output end of the third motor 340 is drivingly connected to one end of the second swing arm 350, and a third mounting groove 351 is opened at the other end of the second swing arm 350, the fourth motor 360 is arranged in the third mounting groove 351, and a first rotating block 371 is provided on the second mounting frame 370, the first rotating block 371 is rotatably connected to one end of the second swing arm 350 away from the third motor 340, the output end of the fourth motor 360 is drivingly connected to the first rotating block 371, and the camera mechanism 400 and the screwing motor 510 are both arranged at one end of the second mounting frame 370 away from the first rotating block 371.

[0053] Through the joint drive of the first mounting frame 310, multiple motors and each swing arm, the camera mechanism 400 and the screwing motor 510 have high flexibility and positioning ability in the limited space under the vehicle, so as to cope with bolted joints in different positions, angles and spatial environments. No matter whether the bolts are high, low or hidden in complex structures, they can be reached and operated quickly and accurately to ensure stable operation under complex working conditions, greatly improve the efficiency and quality of detection and screwing operations, and provide efficient and reliable support for the underbody maintenance work of high-speed EMUs.

[0054] In one embodiment, if Figure 2 and Figure 3 As shown, the mounting base 100 is provided with a third driving mechanism 380, and the third driving mechanism 380 includes a third mounting frame 381, a fifth motor 383 and a second rotating block 384. The third mounting frame 381 is arranged on the mounting base 100, and a fourth mounting groove 382 is opened on the third mounting frame 381. The fifth motor 383 is arranged in the fourth mounting groove 382. The output end of the fifth motor 383 is drivingly connected to the second rotating block 384, and the first mounting frame 310 is arranged at one end of the second rotating block 384 away from the fifth motor 383.

[0055] When the bolted joint is at an inclined angle or partially blocked by an irregular object, the work vehicle can tilt the second drive mechanism 300 through the third drive mechanism 380, so that the second drive mechanism 300 can more flexibly drive the camera mechanism 400 and the screwing motor 510 to approach the bolted joint, ensuring the clarity of image acquisition and the accuracy of the screwing operation. The third drive mechanism 380 further expands the motion range of the second drive mechanism 300. The two work together to enrich the operating dimensions of the work vehicle in three-dimensional space, reduce the situation where bolts cannot be reached or accurately operated due to space limitations, and significantly improve the functional diversity of the work vehicle, providing higher convenience and reliability for inspection and maintenance work in complex space environments such as the bottom of high-speed EMUs, and effectively improving overall operating efficiency and quality.

[0056] Preferably, the first swing arm 330 and the second swing arm 350 can be designed as a retractable swing arm structure. Specifically, a nested telescopic joint can be set inside the first swing arm 330 and the second swing arm 350, which is driven by a hydraulic system or an electric push rod to achieve length adjustment, thereby expanding the working range of the detection work. When facing a bolted connector that is far away, the swing arm is extended so that the camera mechanism 400 and the screwing motor 510 can be easily reached without moving the overall position of the work vehicle, saving time and energy. Secondly, in a complex and narrow space, the swing arm can be flexibly retracted to avoid collision with surrounding components, while accurately locating the target bolt to improve the accuracy of the operation.

[0057] See also Figure 4 Preferably, the screwing adjustment mechanism includes a universal connector 530 and a tool box 540. The output end of the screwing motor 510 is drivingly connected to the universal connector 530. The tool box 540 is arranged on the mounting base 100. The tool box 540 is provided with a plurality of bolt screwing members 541 of different specifications. The plurality of bolt screwing members 541 of different specifications are used to match bolt connectors of different specifications to screw bolt connectors of different specifications. The second driving mechanism 300 is also used to drive the universal connector 530 close to the bolt screwing member 541.

[0058] After the console determines the specifications of the required bolt screw 541 based on the image information analyzed by the camera mechanism 400, it controls the second drive mechanism 300 to move the universal connector 530 to the corresponding bolt screw 541, quickly docks the bolt screw 541, and puts it back into the corresponding placement cavity 544 after use to ensure normal use next time.

[0059] Preferably, a magnetic countersunk hole 531 is provided at one end of the universal connector 530 away from the screwing motor 510, and multiple bolt screwing parts 541 are each provided with a magnetic connection column 542 matching the magnetic countersunk hole 531. A partition 543 is provided in the tool box 540, and the partition 543 divides the tool box 540 into multiple placement cavities 544. Each bolt screwing part 541 is independently arranged in the multiple placement cavities 544, and each placement cavity 544 is provided with an electromagnet. The multiple electromagnets are electrically connected to the control console, and the electromagnet is used to adsorb the magnetic connection column 542 on the bolt screwing part 541.

[0060] When in use, the second driving mechanism 300 first moves the universal connector 530 to the position of the corresponding placement cavity 544. At this time, the console controls the electromagnet in the placement cavity 544 to weaken the magnetism, loosen the adsorption of the magnetic connection column 542 of the bolt screwing part 541, and the magnetic countersunk hole 531 of the universal connector 530 is aligned with the magnetic connection column 542 of the bolt screwing part 541, and the automatic docking is completed by magnetism. After the docking is completed, the second driving mechanism 300 will send the universal connector 530 with the matching bolt screwing part 541 to the bolt connector. The drive motor starts, driving the universal connector 530 and the bolt screwing part 541 to perform the screwing operation on the bolt connector. After the operation is completed, the second driving mechanism 300 returns the universal connector 530 to the corresponding placement cavity 544 of the tool box 540, and the electromagnet re-adsorbs the bolt screwing part 541 to complete a complete screwing process.

[0061] Through the cooperation of the magnetic countersunk hole 531 and the magnetic connecting column 542, the universal connector 530 and the bolt screw 541 can be quickly and accurately connected, avoiding tedious manual installation and greatly improving the working efficiency. At the same time, the electromagnet arranged in the tool box 540 can accurately release and fix the bolt screw 541 according to actual needs, avoiding accidental adsorption of other bolt screws 541, ensuring that the bolt screw 541 is accurately taken out and stored each time, providing efficient and stable support for the screwing operation of the bolt connectors on the bottom of the high-speed EMU.

[0062] Preferably, if Figure 3 and Figure 4 As shown, a marking device 550 is also installed in the placement cavity 544, and the marking device 550 includes a fluorescent liquid nozzle 551 and a fluorescent liquid supply device 552. The fluorescent liquid nozzle 551 is provided with a magnetic connection column 542, and the fluorescent liquid supply device 552 is connected to the fluorescent liquid nozzle 551 through a channel, and the fluorescent liquid supply device 552 is electrically connected to the control console; the electromagnet is also used to adsorb the magnetic connection column 542 on the fluorescent liquid nozzle 551.

[0063] Specifically, when the work vehicle encounters a problem that cannot be solved or needs to replace a bolt, the marking device 550 can be used to mark the position where the operation needs to be performed, such as Figure 5 As shown, when it is necessary to mark the bottom bolt connector, the console will send a signal to the electromagnet in the corresponding placement cavity 544 according to the detection situation, and the electromagnet will release the magnetic connection column 542 adsorbing the fluorescent liquid nozzle 551. Then, the second drive mechanism 300 will drive the universal connector 530 to approach the fluorescent liquid nozzle 551 to complete the docking of the two. Then, the console sends a command to the fluorescent liquid supply device 552, and the fluorescent liquid supply device 552 transports the fluorescent liquid to the fluorescent liquid nozzle 551 through the channel, and the fluorescent liquid nozzle 551 sprays the fluorescent liquid on the bolt connector that needs to be marked. After completing the marking operation, the second drive mechanism 300 returns the universal connector 530 together with the fluorescent liquid nozzle 551 to the placement cavity 544, and the electromagnet re-adsorbs the magnetic connection column 542 of the fluorescent liquid nozzle 551. The marking device 550 can assist the operator to more clearly locate the problematic bolts, avoid work omissions caused by forgetfulness or confusion, and improve the accuracy of the overall work.

[0064] When high-speed EMUs are in operation, a large amount of dirt easily accumulates on the underbody parts, which seriously affects the screwing operation and inspection of the underbody bolted joints. Dirt covers the surface of the bolts, especially at the connection between the nut and the bolt, which prevents the screwing tool from being inserted accurately, easily causing slipping, increasing the difficulty and time of operation, and may also damage the bolts, affecting the tightening effect and endangering operational safety. During the inspection process, dirt blurs the surface features of the bolts, making it difficult for the camera 400 to obtain clear key information. The intelligent analysis system cannot accurately determine whether the bolts are loose or worn due to poor image quality, resulting in deviations in the inspection results and easy omission of safety hazards. Therefore, before the inspection, it is necessary to simply clean the dirt attached to the surface of the bolts to increase the visibility of the image.

[0065] Preferably, a cleaning brush head 560 is also installed in the placement cavity 544, and a magnetic connection column 542 is provided on the cleaning brush head 560. The electromagnet is also used to adsorb the magnetic connection column 542 on the cleaning brush head 560. When the operator finds that there is a lot of dirt in the obtained image information, the second driving mechanism 300 is controlled by the console to move to the position of the cleaning brush head 560 in the placement cavity 544, and at the same time, the electromagnet is controlled to release the adsorption of the magnetic connection column 542 on the cleaning brush head 560. After the docking is completed, the second driving mechanism 300 moves the universal connector 530 with the cleaning brush head 560 to the position where the bolt connection needs to be cleaned, and the cleaning work is started. After cleaning, the second driving mechanism 300 brings the universal connector 530 together with the cleaning brush head 560 back to the placement cavity 544, controls the electromagnet to enhance the magnetism, and re-adsorbs the magnetic connection column 542 on the cleaning brush head 560 to complete the return of the cleaning brush head 560.

[0066] By arranging a cleaning brush head 560 in the placement cavity 544, the functionality of the work vehicle is improved, and simple cleaning work can be carried out when dirt is detected on the bottom parts of the vehicle, so as to ensure that the camera mechanism 400 can obtain better imaging, thereby more accurately analyzing the connection status of the bolted connector at that position, thereby improving the accuracy of the detection operation.

[0067] Preferably, an auxiliary lighting device 110 is provided on the mounting base 100 to illuminate the dark area under the vehicle, so that operations such as filming, inspection, and cleaning can be carried out efficiently in a clear environment.
