Description

Technical Field

[0001] This utility model relates to an automatic cleaning device for railway freight cars, belonging to the field of railway freight car technology. Background Technology

[0002] Railway freight cars are vehicles specifically designed for freight transport in railway transportation. They are classified into general-purpose freight cars and special-purpose freight cars according to their purpose. General-purpose freight cars include open wagons, boxcars, and flatcars, which are suitable for transporting a variety of goods. Special-purpose freight cars, such as coal cars and container cars, are designed for specific goods. Their structure consists of core components such as the car body, bogies, couplers, buffer devices, and braking devices, which respectively undertake the functions of load-bearing, driving stability, connection, and safety control. Automatic cleaning devices are required when cleaning the carriages of railway freight cars.

[0003] Chinese Patent Publication No. CN 219357052 U discloses a cleaning device for the underframe of scrapped railway freight cars, designed to address the problem of arc breakage during plasma cutting due to deposits and rust on the bottom of the freight car interior. This invention includes two supports connected by a crossbeam. Linear guide rails are mounted on both sides of the crossbeam, and at least two sliders are mounted on each rail. A moving platform is connected to each slider, and a moving mechanism is mounted on the moving platform. A drive motor is mounted on the moving platform, and an iron broom is connected to the output of the drive motor. This invention removes rust and deposits from the surface of the freight car underframe, thus preventing arc breakage during subsequent plasma cutting and improving the cutting efficiency of the plasma cutter. The cleaning structure of the above-mentioned device can only move in the left and right directions, and the cleaning work can only be carried out by scraping during the movement. When it can only move in the left and right directions to clean the carriage, it will be impossible to clean the front and rear spaces inside the carriage. At the same time, simply scraping may not be able to remove objects that are firmly stuck to the carriage, resulting in poor cleaning effect and uniformity of the carriage cavity, making it inconvenient for operators to use.

[0004] Therefore, an automatic cleaning device for railway freight cars is proposed. Utility Model Content

[0005] In view of this, the present invention provides an automatic cleaning device for railway freight cars to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial option.

[0023] By setting up cleaning component 1, the steel wire grinding roller 107 is moved into the truck bed through the extension of hydraulic cylinder 104. Then, through the output of rotary motor 106, the steel wire grinding roller 107 grinds and cleans the inner wall of the truck bed, thereby cleaning the debris stuck to the inner wall of the truck bed and improving the convenience of cleaning the truck bed. By setting up adjustment component 2, through the output of drive motor 201 and control motor 208, the first screw block 206 and the second screw block 210 drive the steel wire grinding roller 107 to move in the front-back direction and the left-right direction. By adjusting the steel wire grinding roller 107 in multiple directions, the steel wire grinding roller 107 can clean different areas of the truck bed, improving the flexibility and uniformity of cleaning and making it convenient for operators to use.

[0024] Example 2 like Figure 1-6 As shown, in one embodiment, guide grooves 211 are provided on both the front and rear sides of the movable frame 207.
