Description

Technical Field

[0001] The utility model relates to the technical field of cleaning, in particular to a dry ice cleaning device and a cleaning method for cleaning the bottom of a train. Background Art

[0002] Currently, the cleaning and inspection of the underbody of subways, high-speed trains, and other vehicles primarily relies on traditional manual visual inspections or contact wiping and routine inspections using simple tools. This type of operation involves a wide range of cleaning points, is challenging, and involves a tedious process in a harsh environment. Furthermore, due to human factors, high standards and efficiency cannot always be maintained, leading to high manual cleaning costs. Summary of the Invention

[0003] The technical problem to be solved by the utility model is to provide a dry ice cleaning device for cleaning the bottom of a train, which can be used for detecting and cleaning the bottom status of subways, high-speed railways and other trains, and can greatly reduce the labor intensity of employees.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is: a dry ice cleaning device for cleaning the bottom of a train, comprising a rail car body, at least four lifting legs, and at least four sets of retractable wheels. A battery, a dry ice machine, an air compressor, a motor module, and a cleaning actuator are installed in the rail car body. A visual camera for identifying the parts of the bottom of the train that need to be cleaned is installed above the rail car body. Non-contact ranging sensors and contact collision sensors for providing position detection and anti-collision protection are installed at the front and rear ends of the rail car body. The battery is electrically connected to the dry ice machine, the air compressor, the motor module and the cleaning actuator. The air compressor is connected to the dry ice machine. The cleaning actuator includes a dry ice nozzle, a transverse lifting rod and a rotation module. The dry ice nozzle is connected to the dry ice machine. The lifting legs are installed at the lower part of the rail car body for raising or lowering the height of the device, and the retractable wheels are connected to the motor module.

[0005] Furthermore, the device also includes a wireless network module. The device is suspended and runs under the train rails.

[0006] The dry ice cleaning device and cleaning method for cleaning the bottom of a train proposed in this utility model adopt an integrated design, in which the battery, dry ice machine, air compressor, motor module, cleaning actuator, etc. are all installed in a rail car, and the rail car is operated in a suspended form under the train rails. Visual cameras and sensors are installed above and in front and behind the device, which can achieve self-collision protection and bottom feature recognition. Through the control of the lifting legs, the height is lowered in the maintenance ditch during non-working hours to avoid interference with the train. The telescopic wheels can share the rails with the train and pass through the obstruction of the train wheel set through orderly deformation and extension; non-contact dry ice cleaning is safe and efficient.

[0010] like Figure 1 The figure shows a dry ice cleaning device for cleaning the underside of a train. The device includes a railcar 6, at least four lifting legs 3, and at least four sets of retractable wheels 1. The railcar 6 is equipped with a battery 5, a dry ice generator 4, an air compressor 7, a motor module 2, and a cleaning actuator 9. A visual camera (not shown) is mounted above the railcar 6 to identify areas on the underside of the train that require cleaning. Non-contact distance sensors (not shown) and contact collision sensors (not shown) are installed at both the front and rear ends of the railcar 6 to provide position detection and collision protection.

[0011] Battery 5 provides power to the dry ice dispenser 4, air compressor 7, motor module 2, and cleaning actuator 9 within the device. Air compressor 7 provides compressed air to the dry ice dispenser 4, ensuring dry ice spray pressure. The dry ice dispenser 4 is used to clean the underside of the train. The cleaning actuator 9 includes a dry ice spray head connected to the dry ice dispenser, a transverse lift rod, and a rotation module. These levers and rotation module control the dry ice spray head's height, lateral position, and angle, adjusting them to meet cleaning requirements.

[0012] The lifting legs 3 are installed at the four corners of the lower part of the rail car body and are used to raise or lower the height of the device so that the height can be lowered in the maintenance ditch during non-working hours to avoid interference with the train.

[0013] The retractable wheel 1 can automatically retract in the lateral direction under the control of the motor module 2. When the device is in operation, it automatically detects the position information of the train wheelset through a visual camera and a sensor, and controls the automatic retraction of the retractable wheel 1 so that each wheelset passes through the train wheelset one by one.

[0014] The device also includes a wireless network module. During operation, the device is operated below the train rails 8 in a suspended form.

[0015] A cleaning method based on the above device comprises the following steps:

[0016] S1 Before starting the cleaning work, the lifting legs of the device are lowered to a height and placed in the maintenance trench in the train depot to avoid interference with the train.

[0017] S2 When the train to be cleaned enters the maintenance depot, the device is raised in height by the lifting legs, and then the telescopic wheels are horizontally unfolded. After the telescopic wheels are stably placed on the rails, the lifting legs are retracted and the device enters the cleaning working state.

[0018] S3 The visual camera captures an image of the bottom of the train to be cleaned and transmits the image to the operation and maintenance center via a wireless network. The operation and maintenance center obtains the location data of the train to be cleaned through image recognition processing. The device receives the location data and controls the cleaning actuator and the dry ice machine to perform dry ice cleaning.

[0019] After the S4 cleaning task is completed, the lifting legs extend to touch the ground, lifting the entire device and separating it from the rails. Then, the telescopic wheels retract laterally inward and leave the area above the rails. Finally, the lifting legs retract to lower the entire device to a height that does not interfere with the safe operation of the train.

[0020] In one embodiment, the cleaning data of step S3 may be transmitted to an operation and maintenance center in real time via a wireless network for early warning and other subsequent processing.

[0021] The dry ice cleaning device and cleaning method for cleaning the bottom of a train proposed in this utility model can be used for intelligent detection and fixed-point cleaning of the bottom status of subways, high-speed railways, trucks and other vehicles, effectively reducing labor costs and improving maintenance and cleaning efficiency.

[0022] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
