Abstract
Description
Technical Field
[0001] This utility model specifically relates to the field of track cleaning technology, and more specifically to a mobile cleaning device for mine monorail tracks. Background Technology
[0002] As the core equipment for material transportation in mines, the monorail is exposed to complex environments such as dust, mud, water, and oil stains for a long time. The high humidity environment in the return airway can easily cause dust to form a "paste layer", resulting in a smooth track surface and causing the monorail to slip. Pollutants on the track surface not only increase running resistance, but may also cause safety hazards such as wear of mechanical parts and electrical short circuits, and affect production efficiency.
[0003] Existing track cleaning devices mostly rely on manual cleaning. While this effectively cleans tracks, it is only suitable for tracks with short distances and low elevations. However, as mine depths increase, track lengths also increase. Manual cleaning is no longer sufficient to meet production needs. Existing track cleaning devices can only perform simple wiping of the surface or exterior, failing to effectively remove accumulated dust or stones that have fallen from the mine. This can obstruct crane operation or prevent proper contact between the crane and the track, leading to crane slippage or even backward movement.
[0004] A search revealed Chinese Patent Publication No. CN202020015397.2, which discloses a track cleaning device for a mining monorail crane. The device includes track wheels, vertical plates, scrapers, and connecting plates. Four sets of track wheels are symmetrically installed on both sides of the track. One end of each track wheel is mounted on the vertical plate via a first rotating shaft. The lower parts of the vertical plates on both sides are connected by a first connecting rod. A hanging plate is mounted on the first connecting rod, and the front and rear hanging plates are connected by a connecting plate. A scraper is mounted on one side of each vertical plate, and one side of the scraper is connected to the vertical plate via a second connecting rod. One end of the scraper contacts the track, and the front and rear sets of scrapers are arranged back-to-back.
[0005] The device in the aforementioned patent effectively removes impurities from the track using a scraper during the track cleaning process, and then uses a brush to effectively clean the removed impurities. However, the brush in the aforementioned patent is located on the inside of the vertical plate, so after the impurities are swept away, a large amount of impurities will still adhere to the surface of the track, and the cleaning effect cannot be effectively achieved. In addition, the device in the aforementioned patent has no driving device, so manual driving during the operation is time-consuming and laborious. If a non-powered drive is used, the movement may stop when the scraper collides with a large impurity. Therefore, the device in the aforementioned patent still has certain defects.
