Description

Technical Field

[0001] This application relates to the field of aerial rail transport vehicle technology, and in particular, to the process flow method and inspection warehouse for aerial rail transport vehicles. Background Technology

[0002] Aerial rail transport vehicles are typically used for transporting goods and mainly consist of vehicles and tracks. On the one hand, the vehicles are located below the tracks, and on the other hand, the tracks are erected in the air. They have advantages such as high safety, high integration, low cost, flexible routes, fast construction, small footprint, and environmental friendliness. They can meet the needs of modern urban rail transit and are widely used in the construction of new rail transit in my country.

[0003] As a new mode of transportation, the aerial rail transport vehicle lacks operational experience, and its maintenance process is not as mature as that of traditional rail-based trains.

[0004] While the maintenance process for traditional railcars is relatively mature, the vehicle and track structures differ from those of elevated railcars. Therefore, the maintenance process for traditional railcars cannot be directly applied to elevated railcars. Consequently, there is an urgent need for a clear maintenance process to standardize the maintenance of elevated railcars in order to improve vehicle utilization efficiency.

[0056] Figure 1 A schematic diagram of the inspection process for aerial rail transport vehicles is shown. (See attached diagram) Figure 1 This application provides a process flow method for the inspection of aerial rail transport vehicles, which includes at least steps S1 to S4, as detailed below:

[0057] In step S1, the train enters the inspection depot, the train's status is controlled, and preparations for the inspection operation are initiated.

[0058] In this application, a train inspection operation plan can be prepared before step S1.

[0059] Specifically, the train inspection operation plan can be prepared using the following methods:

[0060] The number of trains and the number of train inspection groups can be obtained by receiving train inspection tasks.

[0061] Based on the number of trains and the number of inspection teams, a train inspection operation plan is prepared, which includes the tasks to be undertaken by each inspection team.

[0062] The prepared train inspection operation plan needs to be communicated to each train inspection team in a timely manner so that each team can prepare for the train inspection according to the plan.

[0063] When train operation conditions change, the train inspection plan should be changed accordingly, and each train inspection team should be notified in a timely manner to avoid confusion.

[0064] The purpose of developing a train inspection plan is to enable each inspection team to carry out its work more effectively and to control the train's status in an orderly manner.

[0065] In step S2, maintenance personnel perform train inspection operations on the train, including bogie maintenance, frame maintenance, and vehicle electrical system maintenance.

[0066] In step S3, train faults discovered during the train inspection process are handled.

[0067] In this application, the handling methods for train malfunctions vary depending on the type of malfunction.

[0068] In step S4, after the train inspection is completed, the final work begins.

[0069] Specifically, the finishing touches include:

[0070] After confirming that no maintenance personnel or tools are left on the train or in the work area, the maintenance personnel remove safety protection measures, clean up the site, and leave the train operation area. After leaving the work area, the maintenance personnel inform the train dispatcher that the train inspection has been completed and complete the cancellation procedures for the train inspection. The train dispatcher restores the train to fully automatic operation mode and notifies the electrical dispatcher to restore power to the train and move the train into the storage line. During the process of moving the train into the storage line, the maintenance personnel need to squat on both sides of the train to observe the train's operating status. After confirming that everything is correct, they fill in the corresponding work record form.

[0071] After the train is temporarily stored in the storage line, it can wait for the dispatching system's waybill tasks to resume normal operation.

[0072] In this application, the preparation work for controlling the train's status and initiating train inspection includes:

[0073] Depending on the vehicle's power supply system, different methods are used to disconnect the vehicle's power.

[0074] After confirming that the vehicle is powered off, set the vehicle to train inspection mode and confirm that the vehicle is in train inspection mode.

[0075] The vehicle is in a state of waiting for inspection during the train inspection process.

[0076] Specifically, after a vehicle enters the inspection depot, maintenance personnel can apply to the train dispatcher for inspection procedures and request the electrical dispatcher to disconnect the vehicle's power. The electrical dispatcher will then disconnect the power to the vehicle. After the train dispatcher confirms the power disconnection, the vehicle will be set to inspection mode to prevent operator errors when the vehicle is in operation. The automatic monitoring system will confirm that the vehicle is in inspection mode and is in a waiting state for inspection, indicating that maintenance personnel can proceed with the inspection.

[0077] Specifically, confirming that the vehicle is in inspection condition includes:

[0078] To confirm that the vehicle will not move, you can check the power supply status of the automatic monitoring system. For example, if the power supply status of the automatic monitoring system is off, then the vehicle will not move.

[0079] When maintenance personnel enter the train inspection area, they observe the vehicle status and confirm that the vehicle is in a dormant state. Maintenance personnel can observe the operating status of the vehicle equipment or listen to the operating sound of the vehicle equipment to judge the operating status of the vehicle equipment and confirm that the vehicle is in a dormant state. For example, they can observe whether the vehicle equipment is running and whether they can hear the sound of the vehicle equipment running. When maintenance personnel observe that the vehicle equipment is not running and do not hear the sound of the vehicle equipment running, they can confirm that the vehicle is in a dormant state.

[0080] Confirming that the vehicle is not in a movement authorization state is to further confirm that the vehicle will not move due to misoperation, thus affecting the safety of the train inspection process. When maintenance personnel apply to the dispatcher to start the train inspection operation, the dispatcher can confirm through the automatic monitoring system that the vehicle has not been granted movement authorization, and thus approve the maintenance personnel's application to start the train inspection operation.

[0081] Confirming that the vehicle is in inspection mode, rather than in operation mode, is to ensure the safety of maintenance personnel during the inspection process.

[0082] In this application, the method of disconnecting the vehicle's power supply in different ways depending on the vehicle's power supply system includes:

[0083] The aerial rail transport vehicle, driven by a linear motor, can disconnect the power to the ground traction converter and the vehicle's internal battery. The power disconnection of the ground traction converter can be accomplished remotely by the dispatcher.

[0084] After disconnecting the vehicle's power, you can test the vehicle for electrical grounding.

[0085] In this application, the bogie maintenance includes:

[0086] On a plane lower than the vehicle bogie, maintenance personnel perform routine maintenance on the vehicle bogie, inspecting the running wheels, safety wheels, various components and fasteners of the bogie braking system, and replacing damaged parts.

[0087] The bogies of the elevated rail transport vehicle are held onto the rail in a U-shape, with the chassis located at the lower end of the bogies. This U-shaped arrangement of the chassis around the container facilitates container transport. The running wheels are located outside the rail, exposing the bogies to the outside of the rail. At a suitable height, such as slightly below the plane of the bogie (which can be 50cm below the lower end of the bogie), maintenance personnel can directly inspect the bogies while standing. In contrast, when inspecting traditional rail-type trains, the bogies are located below the train, requiring maintenance personnel to crawl under the train or lift it for inspection. The former poses a safety hazard, while the latter is time-consuming and labor-intensive.

[0088] Specifically, observe whether the running wheels and safety wheels have scratches or peeling, check whether any components of the bogie braking system have come loose, check the fasteners for looseness, and replace any damaged parts.

[0089] In this application, the frame maintenance includes:

[0090] Inspect the appearance of the frame's center beams, side beams, and fasteners.

[0091] Specifically, the visual inspection of the frame's center beams, side beams, and fasteners includes:

[0092] Check for cracks or dents on the appearance of the frame's center beam, side beams, and fasteners. You can also check the frame fasteners for looseness.

[0093] In this application, the vehicle electrical system maintenance includes:

[0094] Inspect the appearance of electrical equipment components and the condition of wiring connections;

[0095] Check the air gap of the linear motor on the bogie and adjust any air gap distance that does not meet the preset requirements;

[0096] Depending on the vehicle's power supply system, different power supply methods are used to restore power. For example, for an aerial rail transport vehicle driven by a linear motor, a power supply operation application is first submitted. After confirming safety, the power dispatch personnel restore power by remotely controlling the traction converter.

[0097] Maintenance personnel checked whether the display status of the control system was normal and inspected whether the equipment in each electrical cabinet was functioning properly.

[0098] In this application, the inspection of the air gap of the linear motor on the bogie includes:

[0099] Based on the principle of triangular laser ranging, a laser detection probe is used to detect the air gap of a linear motor.

[0100] Specifically, when the train is moving at a preset speed within the inspection depot, based on the principle of linear triangular laser ranging, a laser detection probe can be used to perform online detection of the air gap of the linear motor, obtaining the linear motor air gap detection value. A standard value for the linear motor air gap can be set, which can be a preset required air gap distance. The linear motor air gap detection value and the linear motor air gap standard value are compared, and corresponding actions are taken. For example, if the standard value for the linear motor air gap is set to 10mm, when the linear motor air gap detection value is in the range of 10-15mm, a fault warning is issued, no action is required, and monitoring is strengthened. When the linear motor air gap detection value is greater than 15mm, it is considered that the air gap is out of limit, a fault alarm is issued, and maintenance personnel are notified to carry out maintenance immediately.

[0101] At the same time, maintenance personnel can also use manual ranging to detect the air gap of the linear motor.

[0102] In this application, the handling of train faults discovered during train inspection includes:

[0103] Obtain the train inspection time;

[0104] During the inspection period, maintenance personnel will eliminate the faults and take corresponding actions based on the results of the fault elimination.

[0105] Specifically, the inspection time can be obtained from the inspection work plan or by setting it manually. When maintenance personnel eliminate faults, they should do so in accordance with the scope and quality requirements of the inspection work to ensure that the vehicles meet the quality standards of the originating train.

[0106] In addition, when maintenance personnel discover a train malfunction, they should record the car number and specific details of the malfunction, and inform all train inspection teams to conduct a thorough inspection of the same location. For example, if a malfunction is found in a certain location in car number 1, all train inspection teams should be informed to conduct a thorough inspection of the same location in other cars.

[0107] In this application, the corresponding processing based on the fault elimination result includes:

[0108] If the maintenance personnel eliminate the train fault within the inspection time, the train will be moved to the storage line.

[0109] If maintenance personnel are unable to eliminate the train malfunction within the inspection period, the train will be impounded and transferred to the maintenance depot.

[0110] In this embodiment, the process of inspection of the aerial rail transport vehicle is clearly defined, providing maintenance personnel with a basis and method for inspection, avoiding insufficient inspection and overlapping operations. Based on this, maintenance personnel can quickly inspect the aerial rail transport vehicle, reducing the inspection time, improving the maintenance efficiency and service life of the aerial rail transport vehicle, and enabling the aerial rail transport vehicle to be put into use quickly after inspection, thereby improving vehicle utilization efficiency.

[0111] This application effectively promotes the standardization of maintenance work for aerial rail transport vehicles, improves maintenance quality, ensures transportation safety, effectively meets the daily maintenance needs of aerial rail transport vehicles, and guarantees train operation safety.

[0112] Figure 2 A schematic diagram of the column inspection library in an embodiment of this application is shown. See also: Figure 2 Based on the same inventive concept, according to a second aspect of the embodiments of this application, an aerial rail transport vehicle inspection depot is provided, comprising:

[0113] The multi-level platform 1 is equipped with a tool room 7 and an auxiliary room 6. The height of the platform is designed to match the bogie and the frame.

[0114] The inspection line 2 is set through the platform 1 to form multiple inspection stations 3 located within the platform 1;

[0115] The inlet 8 and outlet 4 are located at the connection between the inspection line 2 and the platform 1.

[0116] The inspection line 2 runs through the platform, allowing trains to enter the inspection depot from the entrance 8 and exit from the exit 4 without turning, effectively reducing shunting frequency and improving vehicle maintenance efficiency.

[0117] Auxiliary room 6 can be set up close to inspection line 2 to facilitate inspection personnel to work nearby. Tool room 7 can be used to store tools and related consumable parts required for inspection.

[0118] Specifically, two platforms 1 can be set up. Platform 1 can be connected to the ground by steel or cement pillars. The sum of the distance between the lower platform 1 and the frame and the height of the frame can be equal to the height of an average adult, such as 1.7m, so that maintenance personnel can stand on platform 1 to inspect the frame. The distance between the two platforms 1 can be greater than the height of an average adult, such as 1.7m, so that maintenance personnel can stand. The lower end of the bogie is higher than the upper platform 1, so that maintenance personnel can inspect the bogie. A third platform can also be set up on top of the two platforms 1 to shield the inspection line and the vehicle, so as to facilitate the inspection work in rainy or snowy weather.

[0119] In addition, the inspection station 3 can be used as the storage station 5. When a mainline vehicle malfunctions, the spare car stored in the storage station 5 can be brought into the mainline from the inspection depot for replenishment.

[0120] The countertop 1 and the ground, as well as adjacent countertops 1, can be connected by stairs.

[0121] In the inspection depot, the inspection operation can be carried out using either the aerial rail transport vehicle inspection process method described in this application embodiment, or other aerial rail transport vehicle inspection processes.

[0122] In addition, the inspection depot can also be set up in the form of a room, with the floor of the room corresponding to the platform 1, and the entrance 8 and exit 4 being openings in the walls of the room.

[0123] It should be noted that the above embodiments are illustrative of this application and not restrictive, and that those skilled in the art can devise alternative embodiments without departing from the scope of the appended claims. In the claims, any reference signs placed between parentheses should not be construed as limiting the claims.
