TECHNICAL FIELD
[0001] The present application relates to the field of rail transit vehicle cleaning, in particular to a method for brushing the connection of marshalling of a car washer. BACKGROUND
[0002] After a period of operation, the train will have a lot of dust and impurities attached to the surface and the connection of marshalling, so the train needs to be cleaned. The traditional rail transit car washer is designed for fixed marshalling vehicles and cannot effectively adapt to the cleaning needs of the connection of different vehicle types such as 4+4 flexible marshalling. In addition, the space of the connection of marshalling is narrow, and the conventional cleaning equipment is prone to collision with the vehicle body, which poses a safety hazard.
[0003] Therefore, a method for brushing the connection of marshalling of a car washer is proposed. SUMMARY
[0004] In view of the deficiencies of the prior art, the present application provides a method for brushing the connection of marshalling of a car washer, which solves the problems of poor compatibility of multi-marshalling vehicles, low cleaning efficiency and high collision risk through multi-stage signal determination, profiling brushing program and active collision avoidance mechanism.
[0005] To achieve the above purpose, the present application realizes the following technical solutions: A method for brushing the connection of marshalling of a car washer, comprising a machine washing device, the front end of the machine washing device is provided with a reverse warehouse entry signal light, a preliminary car washing parking sign, a device start photoelectric, a 4A marshalling rear end washing signal plate, a 4A marshalling rear end washing parking light, a 4A+4A marshalling rear end washing signal plate, a 4A+4A rear end washing parking light, a car washing end position, the method further comprises a detergent spraying station, a preheating / prewetting station, an entry photoelectric switch, an entry signal light, a forward start photoelectric, a front end washing signal light, two 4A+4A marshalling tail end exit signal plates, an isolation switch, an isolation photoelectric, an end washing photoelectric switch, a front end washing parking position, and an end washing photoelectric switch. The method adopts a turn-back type car washing mode, the secondary washing station and the detergent spraying station (foaming station) are turned on when entering the warehouse, and the car is washed when turning back. The method specifically comprises the following steps: S1. Set the front end washing parking sign / light, the 4 marshalling rear end washing parking sign / light, and the 4+4 marshalling parking sign / light, and enable the corresponding parking light according to the marshalling type (4 marshalling or 4+4); S2. The signal system determines whether the connection of marshalling is parked in the parking position; S3. The signal system determines the rising and falling positions of the brush shaft working position and the initial position and the farthest driving position, and needs to set a proximity switch for the walking trolley on the ground to determine the driving position of the walking trolley; S4. Brush the end face of the train at the connection of marshalling; S5. A dynamic anti-collision mechanism is provided during scrubbing to prevent the train from accidentally starting during scrubbing. S6. After the end faces of the train marshalling connections are cleaned, move out of the car washing machine area.
[0006] Furthermore, in step S1, the 4-group rear end parking lights are enabled every time the car is washed, and the 4+4 group parking lights are enabled only in the 4+4 group car wash mode. When the vehicle is parked at the 4-group rear end parking sign position, the forward start photoelectric signal is blocked and it is determined to be in 4+4 group car wash mode. If the forward start photoelectric signal is not blocked, it is determined to be in 4 group car wash mode.
[0007] Furthermore, when the step S2 is judged, when the front end is washed, the end wash photoelectric switch is one blocked and the other unblocked. The blocked one is set as the end wash front photoelectric, and the unblocked one is set as the end wash rear photoelectric. When the rear photoelectric becomes blocked and the front photoelectric changes from blocked to unblocked and then from unblocked to blocked, it is determined that the marshalling connection has reached the parking space. After the operator's judgment, or after a certain period of time, the state of the end wash photoelectric switch has not changed, it can be determined that the vehicle is in a stationary state.
[0008] Furthermore, in step S3, two proximity switches are used on each side of the trolley to ensure accurate signals.
[0009] Furthermore, the scrubbing step S4 includes the following steps: 1) The train stops at the stop sign position at the rear end of the 4-carriage train according to the stop sign instructions; 2) The end washing system starts the brush shaft lifting procedure from the initial position, and the brush shaft remains at zero position (parallel to the track); 3) After the brush shaft reaches the highest position, the end washing walking program is started, and the center line of the swing mechanism reaches 2040mm from the end washing center position; 4) Start the brush shaft swing program and swing the brush shaft to the working position (perpendicular to the track); 5) Start the end-washing and profiling scrubbing program; 6) The brush shaft swings to zero position; 7) Start the walking program and move the end washing system to the initial position; 8) Start the brush shaft descending program and reach the lower limit.
[0010] Furthermore, when the profiling brushing program in step 4 is started, the end wash spray is started first, the brush shaft rotates, and the brush shaft moves downward, and operates according to the normal end wash downward brushing program until it reaches the lower limit. The brush shaft changes the direction of rotation, and the walking mechanism moves, approaches the other end face, and starts the normal end wash upward brushing program after contacting the end face. The center line of the swing mechanism reaches the other side 2040mm away from the end wash center position, and the brush shaft lifting program is started. After the brush shaft reaches the highest position, the end wash spray is stopped and the brush shaft stops rotating.
[0011] Further, when the brush shaft is hit by the train and continuously pushed, the brush shaft changes from the original working position (90° with the track center line) to 40° with the track center line, and the swing motor starts the avoidance program (continues to swing to nearly parallel with the track center line in the offset direction) without causing interference to the other side of the vehicle body, while ensuring that the end of the brush shaft does not scratch the side of the vehicle body when the train continues to move forward. To achieve the brush shaft from the original working position to 40° with the track center line, start the swing motor to start the avoidance program, based on the setting of the original end brush rotating mechanism proximity switch, add 2 groups on each side to determine the position of the brush shaft, to determine the direction of impact and start the avoidance program in the corresponding direction; When the train hits the brush shaft, the brush shaft starts the lifting system to further reduce the impact damage; When the train hits the brush shaft, the alarm mechanism is started. Advantages
[0012] The present application provides a method for washing the connection of marshalling of a car washer. It has the following advantages: 1) The present application provides a method for washing the connection of marshalling of a car washer, which adopts a multi-marshalling compatible design, can handle 4-marshalling and 4+4-marshalling trains, can adapt to different marshalling vehicles, and improves the versatility of the equipment; 2) The present application provides a method for washing the connection of marshalling of a car washer, which can dynamically adjust the path of the brush shaft through the profiling washing program, adapt to the end face profile of different vehicle models, can clean the train more thoroughly, reduce the need for manual intervention, and avoid cleaning dead angles caused by different vehicle models, which can improve the cleaning quality and prolong the service life of the vehicle; 3) The present application provides a method for washing the connection of marshalling of a car washer, which can automatically trigger the avoidance program when the brush shaft detects a collision with the train, and remind the operator through the alarm mechanism, which significantly improves the safety and reduces the risk of equipment damage and train scratches.

The method specifically comprises the following steps: S1. setting a front end washing parking plate / light, a 4 marshalling rear end washing parking plate / light and a 4+4 marshalling parking plate / light, and enabling the corresponding parking light according to the marshalling type (4 marshalling or 4+4); S2. the signal system judges whether the connection of the marshalling train is parked in the parking position; S3. the signal system judges the rising and falling positions and the initial position and the farthest driving position of the brushing shaft working position, and needs to set a proximity switch on the ground for the walking trolley to determine the driving position of the walking trolley; S4. brushing the end face of the connection of the marshalling train; S5. setting a dynamic anti-collision mechanism during brushing to deal with accidental start of the train during end washing; S6. moving the train out of the car washing machine area after the end face of the connection of the marshalling train is washed.
[0017] In step S1, the 4 marshalling rear end washing parking light is enabled every time the car is washed, and only the 4+4 marshalling parking light is enabled in the 4+4 marshalling car washing mode, the forward start photoelectric is blocked to determine the 4+4 marshalling car washing mode when the vehicle is parked in the 4 marshalling rear end washing parking plate position, and the forward start photoelectric is not blocked to determine the 4 marshalling car washing mode.
[0018] In step S2, when the front end is washed, the end washing photoelectric switch is one blocked and one not blocked, the one blocked is set as the front end washing front photoelectric, and the one not blocked is set as the end washing rear photoelectric, when the rear photoelectric becomes blocked and the front photoelectric experiences from blocked to not blocked and then from not blocked to blocked, it is determined that the connection of the marshalling train reaches the parking position, which can be determined by the operator or by the unchanged state of the end washing photoelectric switch after a certain period of time, and it is determined that the vehicle is in a stationary state.
[0019] In step S3, two trolleys are used on each side of the proximity switch to ensure the accuracy of the signal.
[0020] Step S4 includes the following steps when brushing: 1) The train is parked at the end washing position according to the stop board indication after 4 marshalling; 2) The end washing system starts the brush shaft lifting program from the initial position, and the brush shaft remains at zero position (parallel to the track); 3) After the brush shaft reaches the highest position, the end washing walking program is started, and the center line of the swing mechanism reaches a distance of 2040mm from the center position of the end washing; 4) The brush shaft swing program is started, and the brush shaft is swung to the working position (perpendicular to the track); 5) The end washing simulation brushing program is started; 6) The brush shaft is swung to zero position; 7) The walking program is started, and the end washing system is moved to the initial position; 8) The brush shaft lowering program is started, and the lower limit position is reached.

The swing motor starts the avoidance program (continues to swing to nearly parallel to the center line of the track in the offset direction) without interfering with the other side of the car body, while ensuring that the end of the brush shaft does not scratch the side of the car body when the train continues to move forward. To achieve the brush shaft from the original working position to an angle of 40° with the center line of the track, start the swing motor avoidance program, based on the setting of the original end brush rotation mechanism proximity switch, add 2 sets on each side to determine the position of the brush shaft, to determine the direction of impact and start the avoidance program in the corresponding direction; When the train hits the brush shaft, the brush shaft starts the lifting system to further reduce the impact damage; When the train hits the brush shaft, the alarm mechanism is started.
