Description

Technical Field

[0001] This application relates to the field of maintenance equipment technology, and in particular to maintenance devices. Background Technology

[0002] During locomotive maintenance, components such as the screw compressor require disassembly and repair. In related technologies, the maintenance process typically utilizes a second-floor platform in the warehouse, relying on an overhead crane for hoisting to complete the disassembly and assembly. This process involves repeated adjustments to the hoisting position and cumbersome hoisting path planning, resulting in lengthy procedures and prolonged operation time. Furthermore, the overhead crane occupies hoisting resources during maintenance, affecting other hoisting operations and posing certain safety hazards. Additionally, workers are often in a bent-over or squatting position to adapt to the component maintenance location, increasing the complexity of the operation and easily leading to problems such as lumbar muscle strain, knee and ankle injuries. Utility Model Content

[0003] Therefore, it is necessary to provide a maintenance device to address the problems of cumbersome operation and low maintenance efficiency in the existing maintenance mode.

[0010] In one embodiment, the maintenance device further includes a lifting mechanism, which includes a lifting drive and a lifting rod. The lifting drive is disposed within the receiving cavity and is drivenly connected to the lifting rod.

[0011] In one embodiment, the lifting rod extends vertically, the support platform has a through hole, the lifting rod passes through the through hole and protrudes from the support surface.

[0012] In one embodiment, the lifting rod includes a connecting section and a limiting section. The connecting section is connected to the output end of the lifting drive component, and the limiting section is connected to the end of the connecting section away from the lifting drive component. The limiting section protrudes radially from the outer peripheral surface of the connecting section.

[0013] In one embodiment, the maintenance device further includes a hoisting mechanism comprising a robotic arm spaced apart from the support mechanism, the robotic arm being configured to extend to the top of the support surface.

[0016] The aforementioned maintenance device includes a support mechanism and a posture adjustment mechanism. The support mechanism has a support surface, and the guide rail assembly of the posture adjustment mechanism is located on the support surface. The connecting seat of the adjustment assembly is connected to the guide rail assembly via a movable part, which can move along the guide rail assembly. The support platform is rotatably connected to the connecting seat. When the screw compressor components to be maintained are placed on the support platform, the operator can push the adjustment assembly to move the movable part along the guide rail assembly, thereby moving the components and positioning them appropriately. Simultaneously, the posture of the components can be adjusted by rotating the support platform to position them at a suitable angle. Thus, by combining the stable support of the support mechanism with the posture adjustment of the posture adjustment mechanism, the position and angle of the components to be maintained can be precisely adjusted, reducing the difficulty of maintenance work, making maintenance more convenient, and improving the accuracy and efficiency of maintenance work. Furthermore, because the posture of the components to be maintained is adjustable, the operator can complete the maintenance in a comfortable posture, improving efficiency while reducing safety hazards.

[0034] See Figures 1 to 3 The diagram shows a structural schematic of a maintenance device 10 according to an embodiment of this application. The maintenance device 10 provided in this embodiment includes a support mechanism 100 and a posture adjustment mechanism 200. This maintenance device 10 can be used for disassembly, assembly, and performance testing of screw compressors in electric locomotives, offering convenient operation and high efficiency.

[0035] The support mechanism 100 serves as the basic load-bearing structure, supporting other parts of the maintenance device 10. The support mechanism 100 has a support surface 121, which provides a stable support reference for the entire maintenance operation. Specifically, in some embodiments, the support mechanism 100 includes a support cabinet 110 and a support platform 120. The support cabinet 110 can be configured as a table structure and surface-treated using an automated electrostatic spraying process, resulting in a stable structure, aesthetically pleasing appearance, and strong corrosion resistance and impact resistance. For example, the support cabinet 110 can be configured as a table structure 2.3m long and 1m wide, with an overall load-bearing capacity of 1000kg-3000kg. The bottom of the support cabinet 110 can be fixed to the ground with expansion bolts to ensure overall operational safety and reliability. The interior of the support cabinet 110 has a receiving cavity 111, which can be configured as a tool cabinet to store various types of tools, meeting the needs of operators for loading items. For example, the receiving cavity 111 can store maintenance tools to ensure a clean and orderly work site and facilitate quick access to tools by workers. The support platform 120 is located on top of the support cabinet 110 and has a support surface 121. For example, the support platform 120 can be made of stainless steel plate thicker than 10mm using a binding process, and the support surface 121 is flat to accommodate the attitude adjustment mechanism 200 and the screw compressor and its components.

[0036] The attitude adjustment mechanism 200 can perform tasks such as disassembly, inspection, and assembly of the screw compressor. Specifically, the attitude adjustment mechanism 200 includes an adjustment component 210 and a guide rail assembly 220. The guide rail assembly 220 is disposed on the support surface 121 of the support mechanism 100 and is used to provide a motion track for the adjustment component 210 to guide it. In practical applications, according to the actual maintenance situation of the screw compressor, the guide rail assembly 220 is fixed at a suitable position on the support surface 121 of the support mechanism 100, which allows the adjustment component 210 to move within a certain range, for example, within a distance of 0-500mm. The adjustment component 210 includes a connecting seat 211, a movable part 212, and a support platform 213. The connecting seat 211 is connected to the guide rail assembly 220 through the movable part 212. The movable part 212 is configured to move along the guide rail assembly 220, allowing the connecting seat 211 to move horizontally on the support surface 121. The support platform 213 is rotatably connected to the connecting seat 211. For example, the support platform 213 is configured to rotate 360 ​​degrees relative to the connecting seat 211. When components of the screw compressor are placed on the support platform 213, the support platform 213 can drive the components to rotate relative to the connecting seat 211, thereby adjusting the posture of the components for maintenance.

[0037] Through the above structural design, after the components of the screw compressor to be repaired are placed on the support platform 213, the operator can push the adjustment component 210 to move the movable part 212 along the guide rail assembly 220, thereby driving the component to move and placing the component in a suitable position. Simultaneously, by rotating the support platform 213, the posture of the component can be adjusted to a suitable angle. Thus, through the combination of the stable support of the support mechanism 100 and the posture adjustment of the posture adjustment mechanism 200, the position and angle of the component to be repaired can be precisely adjusted, reducing the difficulty of repair work, making repair more convenient, and improving the accuracy and efficiency of repair work. Furthermore, since the posture of the component to be repaired is adjustable, the operator can complete the repair in a comfortable posture, improving efficiency while reducing safety hazards. Compared to existing repair methods, the repair device 10 of this embodiment does not require vehicle intervention, reducing hoisting risks, improving locomotive repair efficiency, and protecting the health and safety of operators.

[0038] See Figure 2 As shown, the guide rail assembly 220 includes guide rails 221 and limiting blocks 222. The guide rails 221 are disposed on the support surface 121 of the support mechanism 100, and the limiting blocks 222 are disposed at both ends of the guide rails 221. For example, the guide rail assembly 220 includes two parallel guide rails 221. Correspondingly, the adjustment assembly 210 includes multiple movable parts 212, which respectively cooperate with the two guide rails 221. The guide rails 221 provide guidance for the movement of the movable parts 212, ensuring the stability of the movement. Limiting blocks 222 are respectively disposed at both ends of each guide rail 221, and the limiting blocks 222 protrude vertically from the top surface of the guide rail 221. Herein, "vertical direction" as used herein refers to the direction of gravity when the maintenance device 10 is installed on the ground. The limit block 222 can prevent the movable part 212 from sliding out of the guide rail 221, avoid equipment failure or safety accidents caused by the movable part 212 leaving the guide rail 221, and help improve the stability and safety of the maintenance device 10.

[0039] Of course, it should be understood that the number of guide rails 221 in the guide rail assembly 220 is not limited to the example described above. For example, in other alternative embodiments, the guide rail assembly 220 may include three, four, five, or more guide rails 221.

[0040] Furthermore, the movable component 212 is configured as a roller, which is rotatably mounted on the connecting seat 211 and can roll along the guide rail 221. The roller structure reduces friction between the movable component 212 and the guide rail 221, making movement smoother. The support platform 213 is rotatably connected to the connecting seat 211 via a bearing 214, and the rotation axis of the roller is perpendicular to the rotation axis of the support platform 213. The rotation axis of the roller is... Figure 1 and Figure 3 The direction perpendicular to the paper plane, that is, the rotation axis of the bearing platform 213. Figure 1 and Figure 3 The vertical direction is such that the support platform 213 can rotate flexibly while moving horizontally, allowing operators to inspect components from different angles, further improving the flexibility and convenience of maintenance operations and increasing maintenance efficiency.

[0041] Optionally, in some embodiments, the movable part 212 can be configured as a slider, which slides in conjunction with the guide rail 221, thus also achieving the function of guiding the movable part 212.

[0042] See Figure 1 As shown, in some embodiments, the maintenance device 10 further includes a lifting mechanism 300, which includes a lifting drive component 310 and a lifting rod 320. The lifting drive component 310 is disposed within the receiving cavity 111 and is drivenly connected to the lifting rod 320. The lifting rod 320 extends vertically, and the support platform 120 has a through hole 122 through which the lifting rod 320 passes and protrudes from the support surface 121. Specifically, the lifting drive component 310 can employ a hydraulic system. For example, the hydraulic system can be equipped with a motor with a power of 1kW, a power supply voltage of three-phase AC380V±10% or single-phase AC220V±10%, a frequency of (50±1)Hz, a load capacity of ≥0.2 tons, and an adjustable stroke of 100-500mm for driving the lifting rod 320, and an automatic pressure relief function. The lifting drive component 310 can drive the lifting rod 320 to lift the parts to be repaired located on the support surface 121. For example, the lifting rod 320 can lift the air duct of the screw compressor, which facilitates the disassembly and assembly of the compressor motor and coupling, and helps to improve the accuracy and efficiency of maintenance operations.

[0043] Further, see Figure 4 As shown, the lifting rod 320 includes a connecting section 321 and a limiting section 322. The connecting section 321 is connected to the output end of the lifting drive component 310, and the limiting section 322 is connected to the end of the connecting section 321 away from the lifting drive component 310. The limiting section 322 protrudes radially from the outer circumferential surface of the connecting section 321, meaning that the limiting section 322 is relatively large. Therefore, the limiting section 322 can more stably support the parts to be repaired, increasing the safety and stability of the lifting process and ensuring the normal operation of the lifting mechanism 300.

[0044] See Figure 1As shown, in some embodiments, the maintenance device 10 further includes a hoisting mechanism 400, which includes a robotic arm spaced apart from the support mechanism 100. The robotic arm is configured to extend to the top of the support surface 121. Specifically, the robotic arm can be fixed to the ground next to the support mechanism 100, with a maximum load capacity of 2 tons. It uses a 220V power supply (or DC 24V power supply), can be remotely controlled, and can extend or retract, and rotate 360 ​​degrees left and right. Thus, the robotic arm can be used to lift, lower, or transfer the parts to be maintained, so as to transport the parts to be maintained to the attitude adjustment mechanism 200. Furthermore, the robotic arm has an emergency stop locking function. When an emergency occurs (such as tipping over, crushing, etc.) in the robotic arm itself or the object being hoisted, pressing the emergency stop button on the robotic arm will stop the robotic arm from working.

[0045] See Figure 1 As shown, in some embodiments, the maintenance device 10 further includes a control mechanism 500, which includes a control panel 510, a connection component 520, and a control module 530. The connection component 520 is connected to the support mechanism 100, the control panel 510 is connected to the connection component 520, and the control panel 510 is electrically connected to the control module 530. Exemplarily, the control module 530 includes an electrical control system and a computer software measurement and control system, which shortens maintenance operation time through intelligent control. The electrical control system uses a microcontroller for control, combined with the computer software measurement and control system to detect the performance of the screw compressor. The computer software measurement and control system uses computer control technology to realize manual or automatic testing functions through measurement and control software, and stores, prints, and queries test data, enabling accurate judgment of test results. The control panel 510 can integrate wireless communication functions such as WIFI and Bluetooth, used to issue commands to the electrical control system and the computer software measurement and control system, collect and save data records, and can interface with office systems. In case of an emergency during maintenance, pressing the emergency stop button on the control panel 510 will stop the entire maintenance device 10 (including the robotic arm) to prevent safety issues. Later, the computer software control system can interface with the maintenance management system (interface reserved), displaying the test interface on the control panel 510. Users can click the corresponding buttons on the control panel 510 to automatically or manually test various performance parameters according to test requirements. Furthermore, a no-load test function can be set, allowing operators to control the no-load test via the control panel 510. In addition, a video recognition system can be integrated later (interface reserved), enabling the digitization of the maintenance process using network video technology, providing work flow reminders, and allowing users to view maintenance status images or video footage.

[0046] Further, see Figure 1As shown, the connecting assembly 520 includes a first connector 521 and a second connector 522. The first connector 521 is connected to the support mechanism 100 and extends vertically. The second connector 522 connects the first connector 521 and the control panel 510 and extends horizontally. This connecting assembly 520 allows the installation position of the control panel 510 to adapt to the operating habits of the workers and the site conditions. It also keeps the control panel 510 far from the support mechanism 100, avoiding interference during maintenance, improving operational comfort and convenience, and further enhancing work efficiency.

[0047] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0048] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
