Description

Technical Field

[0001] This application relates to the field of railway vehicle manufacturing and maintenance technology, and in particular to a dust removal device for railway passenger cars. Background Technology

[0002] During the repair and maintenance of railway passenger cars, cleaning and dust removal of the car body are crucial steps to ensure vehicle quality and extend its service life. In particular, after shot blasting, a large amount of steel shot, putty, dust, and other debris will remain on the inner and outer surfaces of the car body. These debris must be thoroughly removed to ensure the smooth progress of subsequent processes such as primer spraying and steel structure cutting.

[0003] Traditionally, dust removal operations during railway passenger car maintenance have mostly employed open or semi-open working environments, such as using high-pressure air and air guns for blowing or large vacuum cleaners for vacuuming. However, these methods have many shortcomings in practical application.

[0004] While high-pressure air and air guns can remove some dust and debris, the process generates a large amount of dust, severely polluting the work environment and posing a threat to workers' health. Furthermore, the dust may adhere to the outer surface of the vehicle's steel structure, affecting the quality of subsequent primer application. In addition, outdoor cleaning pollutes the surrounding environment, failing to meet current national environmental protection requirements.

[0005] While large vacuum cleaners can reduce dust generation to some extent, their suction power is not ideal. In particular, they often struggle to effectively pick up fine dust and large particles (such as steel shot, screws, and plastic sheeting) adhering to the vehicle's interior, and are prone to clogging the suction hose, thus reducing cleaning efficiency.

[0035] The terminology used in the implementation section of this application is only for explaining specific embodiments of this application and is not intended to limit this application. The implementation of the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0036] like Figure 1As shown in this embodiment, a railway passenger car dust removal device includes a fully enclosed dust removal chamber 1, a passenger car transport device 2, a putty sanding auxiliary moving device 3, a suspended fixed platform 4, and a dust removal system 5. The fully enclosed dust removal chamber 1 provides a closed dust removal working environment. The passenger car transport device 2 transports the passenger car into the fully enclosed dust removal chamber 1. The putty sanding auxiliary moving device 3 is located inside the fully enclosed dust removal chamber 1 and on one side of the passenger car transport device 2, used to assist cleaning personnel in sanding residual putty on the side walls of the passenger car. The suspended fixed platform 4 is erected on one side of the fully enclosed dust removal chamber 1 and close to the top of the passenger car, used to facilitate cleaning personnel in removing dust from the top of the passenger car. The dust removal system 5 works in conjunction with the putty sanding auxiliary moving device 3 and the suspended fixed platform 4 to achieve comprehensive dust removal of the passenger car's surface and interior.

[0037] The railway passenger car dust removal device in this embodiment provides a closed working environment through a fully enclosed dust removal chamber 1, effectively protecting the working environment and personnel health; the passenger car transport device 2 realizes mechanized transportation of passenger cars, greatly improving work efficiency; the design of the putty sanding auxiliary moving device 3 and the suspended fixed platform 4 enhances the thoroughness of cleaning, enabling cleaning personnel to more easily complete sanding and dust removal tasks; the dust removal system 5 works in conjunction with the various devices to ensure high quality and consistency of cleaning operations, achieving comprehensive dust removal of the passenger car surface and interior. The overall device exhibits significant advantages in many aspects.

[0038] like Figure 1 As shown, in this embodiment, lifting doors 6 are respectively provided at both ends of the fully enclosed dust removal chamber 1. The lifting doors 6 can be opened and closed quickly, providing great convenience for the entry and exit of passenger cars. In the process of railway passenger car repair and maintenance, frequent entry and exit of passenger cars is the norm, and the high efficiency of the lifting doors 6 can significantly improve work efficiency and reduce waiting time.

[0039] like Figure 1 As shown, in this embodiment, the bus transport device 2 includes a first track 21, which is laid on the floor inside the fully enclosed dust removal chamber 1 and can extend outward. The bus can move along the first track 21, enabling it to be transported quickly and smoothly into the fully enclosed dust removal chamber 1, reducing the time and labor intensity of manual handling.

[0040] like Figure 1As shown in this embodiment, the putty sanding auxiliary moving device 3 includes a moving trolley 31 and a second track 32. The moving trolley 31 is movably mounted on the second track 32. The moving trolley 31 can move flexibly along the second track 32, allowing the operator to quickly locate the area to be sanded, reducing the time spent on manual handling and adjustment. The movement method of the moving trolley 31 on the second track 32 can be selected according to actual needs, such as manual pushing, electric drive, chain drive, gear and rack drive, hydraulic drive, or magnetic levitation drive.

[0041] like Figure 1 As shown in this embodiment, air sources are respectively installed at both ends of the suspended fixed platform 4. The air sources are connected to air guns through air ducts, which can be used to blow away dust inside or outside the bus. Cleaning personnel stand on the suspended fixed platform 4 and use the air guns to blow away dust from hard-to-reach areas on the top of the bus. The high-pressure airflow of the air guns can effectively blow away accumulated dust and debris, improving cleaning efficiency. The air guns can also be used for areas such as seats, floors, and ceilings inside the bus. Cleaning personnel can adjust the airflow speed and angle of the air guns to blow dust and debris out from gaps and corners, facilitating subsequent sweeping or vacuuming. When performing large-area dust removal operations, the air guns can be used in conjunction with the dust removal system 5. First, the air guns are used to blow up the dust and debris, and then the dust removal system 5 quickly sucks them away, forming an efficient dust removal process.

[0042] like Figures 2 to 4 As shown, in this embodiment, the dust removal system 5 includes an air supply device 51 and a return air dust removal device 52; the air supply port 511 of the air supply device 51 is located at the top of the fully enclosed dust removal chamber 1 and is used to blow air downwards; the return air dust removal port 526 of the return air dust removal device 52 is located on the side of the lower part of the fully enclosed dust removal chamber 1 and is used to recover airflow; the air supply device 51 and the return air dust removal device 52 work together to form a circulating dust removal air path.

[0043] After the air supply device 51 is activated, airflow is blown into the fully enclosed dust removal chamber 1 through the air supply port 511. The airflow blows down from the top, forming a downward airflow that helps to blow up dust and debris on the surface and inside of the bus. The blown dust and debris move with the airflow and eventually settle to the bottom of the fully enclosed dust removal chamber 1 or adhere to other parts on the surface and inside of the bus. The return air dust removal device 52 recovers this dust-laden airflow through its return air dust removal port 526. After the dust-laden airflow enters the return air dust removal device 52, it undergoes filtration, separation and other treatment processes to remove dust. The purified air can then be reused or discharged outdoors. The air supply device 51 and the return air dust removal device 52 work together to form a circulating dust removal airflow path. In this airflow path, airflow continuously blows down from the top, blowing up dust, which is then collected and processed through the return air dust removal port 526 at the bottom. The design of the circulating dust removal airflow path enables the dust removal system 5 to work continuously and efficiently, constantly reducing the dust concentration on the surface and inside of the bus, and maintaining the cleanliness and stability of the internal environment of the dust removal chamber.

[0044] like Figure 2 As shown in this embodiment, the air supply device 51 includes a blower 512 and an air supply pipe 513. The blower 512 is connected to the air outlet 511 through the air supply pipe 513.

[0045] like Figure 2 As shown in this embodiment, the return air dust removal device 52 includes a cyclone dust collector 521, a cartridge dust collector 522, and a return air fan 523. The cyclone dust collector 521 is connected to the return air dust removal port 526 through the return air duct 524 and is used for preliminary filtration of large dust particles. The cartridge dust collector 522 is connected to the cyclone dust collector 521 and is used for fine filtration of fine dust particles. The return air fan 523 is connected to the cartridge dust collector 522 and is used to draw dust-containing air from the fully enclosed dust removal chamber 1 and transport it to the cyclone dust collector 521 and the cartridge dust collector 522 for filtration through the return air duct 524.

[0046] After the return air fan 523 starts, it generates a strong suction force, drawing in dust-laden air from the fully enclosed dust collection chamber 1 through the return air dust collection port 526. The dust-laden airflow first enters the cyclone dust collector 521. Inside the cyclone dust collector 521, the airflow enters tangentially, forming a rotating airflow. Under the action of centrifugal force, large dust particles are thrown against the wall and fall into the dust hopper, achieving preliminary filtration. The airflow after preliminary filtration by the cyclone dust collector 521 still contains some fine dust. This airflow then enters the cartridge dust collector 522. Inside the cartridge dust collector 522, as the airflow passes through the filter medium (such as polyester fiber filter media) of the cartridges, fine dust is trapped on the surface of the cartridges, while the purified air is discharged through the cartridges. The large dust particles in the dust hopper of the cyclone dust collector 521 and the fine dust on the surface of the cartridges of the cartridge dust collector 522 can be cleaned and collected periodically by a cleaning device (such as a pulse jet cleaning device). The collected dust can be further processed or recycled; the purified air can be discharged from the fully enclosed dust removal chamber 1 by the return air fan 523 or other means, or it can be recycled as needed.

[0047] like Figure 2 As shown, the return air dust removal device 52 in this embodiment achieves efficient filtration of dust-laden airflow within the fully enclosed dust removal chamber 1 through the combined use of a cyclone dust collector 521 and a cartridge dust collector 522. The cyclone dust collector 521 is responsible for the initial filtration of large dust particles, reducing the burden on the cartridge dust collector 522; the cartridge dust collector 522 is responsible for the fine filtration of fine dust particles, ensuring the quality of the emitted air. The return air fan 523 serves as the power source, providing the necessary suction to allow the dust-laden airflow to pass smoothly through the entire dust removal system 5. The entire system has a compact structure, is easy to operate, and has high dust removal efficiency, making it suitable for dust removal operations during the overhaul and maintenance of railway passenger cars.

[0048] The general working principle of a dust removal device for railway passenger cars is as follows:

[0049] The lifting door 6 of the fully enclosed dust removal chamber 1 opens to welcome the passenger bus. The dust removal system 5 (including the air supply device 51 and the return air dust removal device 52) is started and keeps running to ensure a clean environment inside the dust removal chamber.

[0050] After the bogie wheels of the bus are aligned with the first track 21, the bus is smoothly transported into the fully enclosed dust removal chamber 1 using the first track 21, and the lifting door 6 is closed. Preparation for dust removal is underway. The moving trolley 31 of the putty sanding auxiliary moving device 3 moves along the second track 32, quickly positioning itself to the area requiring sanding according to the cleaning personnel's needs. Cleaning personnel sand the remaining putty on the side walls of the bus on the moving trolley 31, while the dust removal system 5 continues to operate, promptly removing the dust generated during sanding. Cleaning personnel stand on the suspended fixed platform 4 and use an air gun to blow away dust from hard-to-reach areas on the top of the bus. The high-pressure airflow from the air gun effectively blows away accumulated dust and debris, while the dust removal system 5 quickly removes this dust, maintaining clean air within the dust removal chamber. Throughout the dust removal process, the air supply device 51 continuously blows airflow into the dust removal chamber, lifting dust and debris from the surface and interior of the bus. The return air dust removal device 52 recovers these dust-laden airflows through the return air dust removal port 526, and removes large particles and fine dust through a combination filtration of the cyclone dust collector 521 and the cartridge dust collector 522. The purified air can be recycled or discharged outdoors, while the dust is collected and further processed or recycled. After the dust removal operation is completed, the conveyor platform 22 of the bus transport device 2 moves again along the first track 21, smoothly sending the bus out of the fully enclosed dust removal chamber 1. The lifting door 6 closes to ensure that the clean environment inside the dust removal chamber is not disturbed by the outside world.

[0051] The entire device, through the coordinated operation of its various components, forms an efficient and continuous dust removal process. Dust removal system 5 remains continuously operational, ensuring high quality and consistency in dust removal operations and achieving comprehensive dust removal of the passenger car's surface and interior. Furthermore, the device is compact in structure and easy to operate, making it suitable for dust removal operations during railway passenger car repair and maintenance.
