TECHNICAL FIELD
[0001] Embodiments of the present disclosure relate to the technical field of bullet train component maintenance, and in particular to a bullet train axle end component maintenance line. BACKGROUND
[0002] The bullet train axle end components are numerous in quantity, and the parts are also numerous. The existing operation personnel often adopt the mode of continuously maintaining the same item in multiple pieces, and multiple people simultaneously carry out the maintenance of the same kind of parts of the axle end components, and cross each other. The trays are laid on the ground for manual maintenance, and the operation personnel need to squat or sit on a small stool to frequently cross each other. The operation posture is inconvenient and laborious, and the operation personnel need to carry tools around the tray, which increases the labor intensity. For the maintenance requiring measurement and record, the measurement is completely manual, and the record is input into the computer, which has human error. The scrap axle end components and the spare parts are recorded and managed by manual. The measurement data cannot be automatically output, the maintenance record cannot be connected to the information system, and the complete process of the maintenance data flow cannot be formed for quality control, maintenance process analysis, and optimization of maintenance management. At present, the trays are directly laid on the ground in the maintenance operation site, and there is no three-dimensional storage rack in the site, which reduces the utilization rate of the site and causes resource waste. The incoming and outgoing materials are not easy to turn over and cannot be stored separately.
[0003] At present, the axle end component maintenance has the following problems:
[0004] The axle end components are stored in the trays in the site, and the operation personnel maintain the components on the trays. The position of the maintenance tray determines the operation position. The to-be-maintained components and the maintained components are not strictly separated, and the components are easy to be confused. The incoming and outgoing materials are not easy to turn over and cannot be stored separately. The logistics area and the operation area are crossed, the forklift enters the operation area, and there is a safety risk.
[0005] The maintenance data of the on-site maintenance process are recorded by manual, which has human error, and cannot form a complete maintenance data flow for quality management, maintenance process analysis, and optimization of maintenance management.
[0006] The operation personnel need to squat or sit on a small stool to work, the operation posture is inconvenient and laborious, and the operation personnel need to carry tools around the tray, which increases the labor intensity.
[0007] At present, the production capacity of the axle end component maintenance is about 0.5 standard groups per day. With the increase of the maintenance quantity of the bullet train section, the operation site of the flat type operation also increases. The existing site cannot meet the storage of the maintenance components with the planned production capacity, and the turnover of the maintenance components is difficult.
[0008] Necessity of improving the maintenance line: 1. The shaft end component is an important component of the shaft end of the motor train unit. The quality of the maintenance and the refinement of the maintenance process and means are directly related to the operation safety of the motor train unit. With the increasing of the overall maintenance amount of the motor train depot, the existing maintenance mode is difficult to meet the related maintenance capacity requirements. The construction of the maintenance line is beneficial to improve the maintenance efficiency and ensure the capacity to meet the related capacity requirements of the motor train depot.
[0009] 2. The layout of the shaft end component maintenance site is not reasonable in process flow, and the lean maintenance is not formed. The maintenance process cannot be controlled, the maintenance data cannot be automatically formed into electronic documents, the personnel cost is high, the maintenance period is uncontrollable, which causes serious resource waste. The newly-built rotary arm maintenance line is beneficial to improve the independent repair level of the motor train unit, and effectively ensures the safety, controllability of the maintenance quality and efficiency.
[0010] 3. The maintenance site area is small and needs to be re-planned. The existing maintenance field is fully and reasonably utilized. The newly-built maintenance line can fully utilize the existing maintenance site, divide the related operation area and material storage area, and improve the utilization rate of the maintenance site.
