Description

Technical Field

[0001] The invention belongs to the technical field of metal mines, and in particular relates to a track cleaning device and a cleaning method. Background Art

[0002] Track refers to the route paved with strips of steel for trains, trams, etc. to travel on. During the long-term operation of the track, the sludge or slag dropped from the rail transport vehicle may adhere to its surface. When the train wheels pass over it, sticky black sludge will form, which is easy to stick to the top of the rail, making it particularly difficult to brake and accelerate the train. The track is usually covered with ice in winter, especially in the winter in the north, when the temperature is low. In severe cases, it may affect the normal use of the track and even threaten the safe operation of the mine car. In response to this major problem, the track cleaning device was invented. The first hazard of track debris is that each wheel of the mine car has a brake device. If slag is rolled into the wheel, it is easy to affect the braking performance of the mine car. Once emergency braking is required to slow down the speed of travel, it is also easy to cause safety hazards. The second problem is the most serious, because the wheels and rails must fit tightly to ensure safe driving. If slag is sandwiched between the two, the friction will be reduced, making derailment very likely to occur. Finally, if the slag that falls on the railway is not cleaned up in time, the track will be severely worn, which in turn affects the stability of the transport vehicle's operation and poses a safety hazard.

At least two brushes are arranged below the small flatbed car, so that the brushes can clean the tracks on both sides at any time during the operation of the small flatbed car, reducing the possibility of cement dust accumulating into blocks, and maintaining the transportation track to a certain extent. Through the setting of the wedge-shaped metal scraper, during the operation of the small flatbed car, the metal scraper can scrape the cement agglomerated on the track, thereby effectively removing the cement agglomerated on the track; however, although it can clean most of the track attachments, its strength is limited, and there are still attachments such as stubborn or water-mixed cement blocks that are not easy to be cleaned.

The scraper device includes two slide grooves 20, a slideway 17 arranged inside each slide groove 20 and slidably connected to the slide groove 20, a limit block 16 and a limit block 2 18 connected to the slide groove 17, an ear plate 15 connected to the limit block 16, an ear seat plate 14 rotatably connected to the ear plate 15, and a moment spring 19 arranged outside the slide groove 17. A triangular slider 21 is arranged at one end of the slide groove 20 that cooperates with the moment spring 19. A scraper assembly 22 is arranged at the end of each slide groove 20. A baffle 23 is arranged at the lower part of each slide groove 20, and an arc-shaped baffle 24 is arranged on the baffle 23. Furthermore, the number of arc-shaped blocks 24 is three, and the height is continuously increased. When sludge and slag appear on the mine car track, the scraper assembly 22 starts to clean the track. When the scraper assembly 22 encounters greater resistance, the scraper assembly 22 moves backward, the rectangular spring 19 is compressed, and the triangular slider 21 moves to the arc-shaped block 24 set on the baffle 23. The triangular slider 21 is lifted, the scraper assembly 22 is lifted, and the scraper assembly 22 resumes its original motion state under the elastic force of the rectangular spring, so that the difficult-to-clean track can be achieved. The cleaning is carried out in sections multiple times to loosen the compacted sludge, slag and ice layers. When the difficult-to-clean sludge and slag appear at a high height on the mine car track, the scraper assembly 22 continues to move backward, the moment spring 19 continues to be compressed, and the triangular slider 21 moves to the middle arc or the maximum arc of the arc stopper 24 set on the baffle 23. The triangular slider 21 continues to be lifted higher, and the scraper assembly 22 continues to be lifted higher, so as to reduce the resistance of the scraper assembly 22, prevent damage to the scraper assembly 22, and automatically avoid difficult-to-clean sections.
