Description

Technical Field

[0001] The utility model relates to the technical field of bottom side-dumping unloading stations for mine mining, and specifically relates to a detachable curved rail structure for bottom side-dumping mine car unloading. Background Technique

[0002] With the rapid development of China's national economy, the demand for ore has been increasing year by year. Small mine cars with volumes of 2m3, 4m3, and 6m3 can no longer meet the current needs of mine production. Large-volume mine cars are favored by mining enterprises. In order to cooperate with the unloading of such large-volume mine cars, the common unloading station forms in large mines at present include curved rail side-dumping unloading stations, bottom side-dumping unloading stations, and bottom-dumping unloading stations. The existing unloading stations mainly include: unloading curved rails in contact connection with the car body frame, supporting wheels for supporting the car body of the bottom side-dumping mine car, and supporting rails.

[0003] The current unloading stations generally do not have a driving device. Mainly relying on the weight of the ore carried by the mine car and the self-weight of the car body frame of the mine car, the mine car receives a horizontal thrust to push the train to continue moving forward. The car body frame of the mine car automatically opens downward along the curved rail by its own weight and the weight of the ore carried. The unloading wheels at the rear end of the car body frame roll downward along the curved rail, the bottom door of the car gradually opens, the mine car passes through the center point of the unloading station, all the ore is unloaded, the unloading wheels roll over the inflection point of the curved rail upward, the car frame and the car body gradually close, and the bottom door closes.

[0004] In the prior art, due to the large friction between the unloading wheels at the bottom of the mine car and the curved rail, it is easy to cause large wear of the curved rail and a short service life cycle, and it needs to be replaced regularly. When replacing the curved rail, it is necessary to carry out split demolition and installation, the operation is complex, the replacement time is long, and it affects production.

[0005] Therefore, we make improvements on this and propose a detachable curved rail structure for bottom side-dumping mine car unloading. Content of the Utility Model
