Description

Technical Field

[0001] This utility model belongs to the field of traction motor and ventilation fan maintenance, specifically to a maintenance line for the maintenance of ventilation fans used in high-speed trains. Background Technology

[0002] The ventilation fan is the most important part of a railway vehicle. Its main function is to cool the traction motor unit, ensuring that the motor maintains stable performance under high load, thereby extending the motor's service life. When a train set reaches its maintenance mileage, the traction motor and ventilation fan need to be disassembled and inspected. The main purpose is to ensure the normal operation of the traction motor and the entire train set, extend its service life, improve safety and stability, and prevent train set failures and accidents.

[0003] Currently, the maintenance of ventilation fans mainly consists of three parts: first, the maintenance of mechanical components, such as filters, impellers, and supports, which is carried out by the mechanical maintenance team, including sheet metal work and paint touch-up; second, the maintenance of the traction motor, which is carried out by the traction motor maintenance team, including bearing, dynamic balancing, and pressure and speed testing; and third, the final assembly team, which performs final assembly and overall testing on the overhauled components. For these maintenance tasks, disassembled parts are often transported to the corresponding teams for maintenance. Due to the different parts, multiple transport devices are needed to transport the disassembled parts to different teams. After maintenance, the parts are then transported to the assembly team for assembly. While this maintenance production line can complete the maintenance of ventilation fans, the different teams located in different areas result in significant time spent on transportation during the maintenance process and high transportation costs. Furthermore, during the final assembly process, if any parts fail maintenance, a considerable amount of time is required for re-delivery. The long transfer time between teams leads to low maintenance efficiency. Utility Model Content

Figure 1As shown in the figure, the maintenance line includes a buffer area 1 for decomposing, a disassembly area, a maintenance area, an assembly test area, and a finished product storage area 11. The buffer area 1 for decomposing, the disassembly area, the maintenance area, the assembly test area, and the finished product storage area 11 are arranged in the same workshop to form a complete maintenance line for the ventilator overhaul;

[0054] Among them, the buffer area 1 for decomposing is set at the entrance position in the workshop and is used for temporarily storing the ventilators to be decomposed; the disassembly area is set on the side of the buffer area 1 for decomposing and is used for forming an area for disassembling the ventilators to be decomposed; the maintenance area is set on the side of the disassembly area and away from the buffer area 1 for decomposing, and is used for forming an area for maintaining the parts disassembled in the disassembly area; the assembly test area is set on the side of the maintenance area and away from the disassembly area, and is used for forming an area for testing the maintained parts and reassembling the tested parts into a ventilator; the finished product storage area 11 is set on the side of the assembly test area and away from the maintenance area, and is used for forming an area for storing the reassembled ventilators; a linear transportation component is set at the same side position of the disassembly area, the maintenance area, and the assembly test area in the workshop, and is used for transporting objects between the disassembly area, the maintenance area, and the assembly test area; through the integrated maintenance line, the area of the workshop to be built for the ventilator overhaul is reduced. At the same time, through the integrated production line, the transportation time of the parts after disassembly during the ventilator overhaul is reduced, so that the parts after the ventilator is disassembled can be directly transported to the next process through the transportation equipment set in the same workshop, saving the transfer time of the parts after disassembly and improving the overhaul efficiency; in this solution, the buffer area 1 for decomposing, the disassembly area, the maintenance area, the assembly test area, and the finished product storage area 11 form a complete overhaul process area for the entire ventilator. Lifting equipment or hoisting equipment, such as electric hoists, etc., will be set in the area and between adjacent areas. The specific processes involved in the area are existing operation means and will not be elaborated here.

[0055] Such as Figure 1 and Figure 2 As shown in the figure, the buffer area 1 for decomposing includes a plurality of trays 101. The trays 101 are used for placing the ventilators to be decomposed. The plurality of trays 101 are arranged in a matrix at the entrance position inside the workshop. A plurality of support bars are provided on the bottom end surface of the tray 101. The plurality of support bars are arranged in parallel to form a "Sichuan" shape for clamping the forklift forks. Through the trays 101, the ventilators to be maintained transported to the workshop entrance are stored neatly, forming a standardized storage space, improving the stacking efficiency, and also facilitating the movement of the trays 101, thereby saving the storage time and facilitating the management of the ventilators to be decomposed.

[0056] Such as Figure 1 and Figure 2As shown, the disassembly area includes a fan disassembly area 2 and a motor disassembly area 3. The fan disassembly area 2 is located inside the factory building on the side of the pallet 101, and the motor disassembly area 3 is located inside the factory building on the side of the fan disassembly area 2. The motor disassembly area 3, the fan disassembly area 2, and the pallet 101 are arranged in a row along the length of the factory building. An electric crane is installed on top of the fan disassembly area 2 inside the factory building. The electric crane is used to transport the pallet 101 containing the fan to be disassembled to the fan disassembly area 2. After disassembly, the parts obtained from the disassembly of the fan disassembly area 2 are then transported to the motor disassembly area 3 for disassembly. By using separate disassembly areas for independent disassembly, the fan disassembly process is independently divided, improving the disassembly efficiency of the fan.

[0057] like Figure 1 and Figure 2 As shown, the ventilation fan dismantling area 2 includes a ventilation fan dismantling platform 201, which is located on the side of the pallet 101 and away from the factory entrance. The platform 201 contains a storage cavity for storing dismantling tools. Multiple accessory baskets 203 and a motor buffer tray 202 are located on the side of the ventilation fan dismantling area 2. A cleaning tray is placed on the top surface of the motor buffer tray 202 to hold the motors obtained from the dismantled ventilation fans. A first electric crane 204 is located above the ventilation fan dismantling platform 201 inside the factory. The first electric crane 204 is used to transport the pallet 101 and the ventilation fans to be dismantled onto the platform 201, where workers can dismantle the ventilation fans with the assistance of the dismantling equipment. This area only involves the dismantling of the ventilation fans, reducing the workload of the staff. Simultaneously, the maintenance process for the ventilation fans is broken down, simplifying the work for the staff in the work area and improving maintenance efficiency. The ventilation fans are dismantled into multiple parts. Under the action of the first electric crane 204, the motor is moved to the cleaning tray on the motor buffer tray 202 for temporary storage. Other parts are moved to the parts storage box 203 for temporary storage. Inside the factory, a guide rail is installed parallel to the length of the factory above the motor buffer tray 202.

[0059] like Figure 1 and Figure 3As shown, the motor disassembly area 3 includes a motor disassembly platform 301, which is located inside the factory, next to the ventilation fan disassembly platform 201 and away from the tray 101. A partition plate 302 is provided on the motor disassembly platform 301, dividing the upper end face of the platform into three areas arranged side-by-side: a motor rotor disassembly area 303, a motor stator disassembly area 304, and a stator-rotor separation area 305. The motor stator disassembly area 304 is located on the upper end face of the motor disassembly platform 301, closer to the line transport assembly. The central position is the stator-rotor separation area 305. The motor is disassembled sequentially through the motor rotor disassembly area 303, the motor stator disassembly area 304, and the stator-rotor separation area 305, completing the disassembly of the motor and the screening of the disassembled parts. Each area completes one process, realizing the orderly division of electrolytic disassembly work and improving the disassembly efficiency of the motor. Inside the factory, a robotic arm 308 is set on the side of the motor disassembly platform 301 to grab the disassembled parts of the motor and put them onto the line transport assembly. The robotic arm 308 is used to transport the parts, reducing the workload of the staff.

[0060] Preferably, a nameplate reader 306 is provided on the side end face of the motor disassembly platform 301 near the line transport component. The nameplate reader identifies the personnel who will operate on the motor disassembly platform 301, preventing other personnel from entering the area and causing safety accidents, and also monitors the entry information of the operators. A bearing disassembly device 307 is provided on the side end face of the motor disassembly platform 301 away from the line transport component.

A vacuum cleaner 402 is installed on the side of the cleaning platform 401 to remove dust from the area, ensuring good air quality in the motor cleaning area 4. A cleaning tank is provided on the upper end face of the cleaning platform 401, and the cleaning tank is filled with cleaning fluid. The cleaning solution is used to clean the parts by transporting them into the cleaning tank. The motor inspection area 5 includes a motor inspection platform 501, which is located next to the cleaning platform 401 and away from the motor disassembly platform 301 in the factory.

The motor testing area 8 is located on the side of the motor assembly area 7. Partitions are installed on the sides of the rotor and stator pre-assembly area 6 and the motor assembly area 7 within the workshop, separating them into independent work areas. This allows the rotor and stator pre-assembly area 6, the motor assembly area 7, and the motor testing area 8 to independently complete their respective processes. During motor processing in these areas, there is no process interference with other work, improving motor processing efficiency while ensuring stable processing of electrical energy according to the set procedures, avoiding missed inspections. The fan processing area includes a fan unit assembly area 9 and... The ventilation fan unit test area 10 and the ventilation fan unit assembly area 9 are located within the factory building, between the motor test area 8 and the finished product storage area 11. Motors that have passed the motor test in area 8 are transferred to the ventilation fan unit assembly area 9 for assembly with other ventilation fan components. After assembly, they are transferred to the ventilation fan unit test area 10 for testing. Ventilation fans that pass the test are then transferred to the finished product storage area 11. All these processing steps are independently set up, and the processing steps in each area are not related to other steps, thus avoiding missed inspections during ventilation fan maintenance. Furthermore, each step is set up in the same factory building according to the ventilation fan testing process flow, saving transportation time and costs during ventilation fan maintenance and improving maintenance efficiency.

An end cover press-fitting machine 603 is installed on the side of the stator assembly platform 605. In the rotor and stator pre-assembly area 6, the rotor in the motor is tested by the rotor dynamic balancing machine 601. If the dynamic balance test is passed, the rotor and stator are assembled through the cooperation of the rotor assembly platform 604, bearing press machine 602, end cover press machine 603 and stator assembly platform 605. The initial assembly and dynamic balance test of the motor are completed in the rotor and stator pre-assembly area 6. The rotor and stator test and rotor and stator assembly are integrated into one process area, which shortens the transportation time of rotor and stator test and rotor and stator assembly, reduces the transportation cost of rotor and stator test and rotor and stator assembly, and improves the maintenance efficiency of the motor.

[0064] like Figure 1 and Figure 4 As shown, the motor assembly area 7 is equipped with an assembly machine 701, on which an automatic motor assembly machine is installed.
