Description

Technical Field

[0001] This utility model relates to the field of track cleaning technology, and more specifically, to a track cleaning device for rail transit. Background Technology

[0002] With the rapid development of urban rail transit, the frequency of train operation is increasing, and various debris, dust, oil stains and other pollutants easily accumulate on the tracks. The presence of these pollutants not only affects the safety of train operation, such as causing accelerated wear of train wheelsets and reduced braking performance, but also shortens the service life of tracks and related equipment.

[0003] Patent CN 222120081 U discloses a track cleaning device for rail transit, belonging to the field of rail transit technology. It includes a base plate with two support frames on its front side. A cleaning component is housed within each support frame. A protective frame is located on the side of each support frame, housing a motor connected to the cleaning component. A striking component is also located within the protective frame, overlapping the cleaning component. A transmission component is located on the side of the cleaning component. This track cleaning device for rail transit, through the arrangement of a motor, rotating rod, brush roller, cam, striking rod, and connecting plate, allows the motor to drive the brush roller to clean the rails. Simultaneously, the striking vibration of the striking rod against the brush roller maintains the cleanliness of the brush roller itself, thus ensuring the normal operation of the rail transit system.

[0004] The aforementioned device uses brush rollers to clean the tracks. The brush rollers wear down very quickly when in contact with the rails. Furthermore, the device is not adjustable and therefore cannot be adjusted according to track spacing, track shape, etc. The device is also quite bulky and not easy to carry.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0006] In view of the problems in the related technologies, this utility model proposes a track cleaning device for rail transit to overcome the above-mentioned technical problems existing in the existing related technologies.

[0007] Therefore, the specific technical solution adopted by this utility model is as follows:

[0008] A track cleaning device for rail transit includes a track and a U-shaped plate installed outside the track. An auxiliary travel wheel is installed at the top inner side of the U-shaped plate, and a drive wheel is installed between the auxiliary travel wheels. A connecting plate is installed at the top of the U-shaped plate, and a water tank is fixedly installed at the center of the top of the connecting plate. A booster pump is fixedly connected to the outside of the water tank, and a water pipe is fixedly connected to the outlet of the booster pump. An arc-shaped pipe is fixedly installed at the other end of the water pipe, and a nozzle is fixedly connected to the arc-shaped pipe. A handle is fixedly connected to the top of the water tank.

[0009] As a further embodiment of this utility model, the U-shaped plate is provided in a group, the connecting plate is arranged in an H-shape, and the U-shaped plate and the connecting plate are fixedly connected by bolts.

[0010] As a further embodiment of this utility model, a shaft is fixedly connected to the center of the drive wheel, a worm gear is fixedly connected to the outer side of the shaft, a worm is meshed with the outer side of the worm gear, and a drive motor is installed at the end of the worm.

[0011] As a further embodiment of this utility model, a protective plate is installed on the outside of the worm wheel, worm, and drive motor, and the worm wheel and worm are rotatably connected to the protective plate.

[0012] As a further embodiment of this utility model, the water tank is provided with batteries on the front and rear sides, and a controller is fixedly connected to the outside of the water tank. The controller includes a microcontroller, an oscillation circuit, a power management module, a remote control module, and an encoding module.

[0013] As a further embodiment of this utility model, a miniature air pump is installed inside the water tank, the arc-shaped tube is fixed to the water tank by a fixing rod, and the nozzles are arranged at equal intervals around the circumference.

[0015] The beneficial effects of this utility model are as follows:

[0016] This invention utilizes a U-shaped plate, drive wheel, water tank, arc-shaped pipe, and nozzle to place the device on a track. A drive motor drives a worm gear, which in turn drives a rotating shaft. This shaft, in turn, drives the drive wheel, propelling the device along the track. A torsion spring presses a positioning plate against the center of the track, causing the positioning wheel to engage with the track, ensuring stability and adaptability to various track shapes. Cleaning fluid is injected into the water tank, and an internal air pump pressurizes the tank. A booster pump then directs the cleaning fluid through a water pipe into the arc-shaped pipe. The cleaning fluid within the arc-shaped pipe is then sprayed at high speed from the nozzle, rapidly cleaning the track and removing dust, oil, and other contaminants. This device is simple in structure, small in size, highly efficient, and highly adaptable. Attached Figure Description
