As the name implies, the bottom dump car can unload gangue from its bottom bin door, and its structural features are as follows:
1. The bottom unloading bin door is designed to be double open. Its advantage is that it can realize the gradual unloading of gangue. When the tramcar is running on the unloading rack, the bin door can be opened successively under the action of the curved rail, so that the gangue can be unloaded in two times, avoiding the instantaneous heavy load on the belt conveyor caused by one-time unloading, which is conducive to the safety of equipment operation.
2. The operation mode of the bottom dump tramcar body on the unloading frame is designed as the supporting wheel bearing type. Use the component force of the gravity of the inclined roadway transport car in the direction of the roadway to slowly run along the bearing wheel, while the wheel runs along the curved track under its own gravity, so that the front and rear bin doors are opened in turn to realize the unloading of gangue.
The application of bottom dump tramcar and unloading station has created a new mode of auxiliary transportation for inclined roadway uphill construction, broken the bottleneck restricting productivity, and greatly improved the efficiency of uphill construction. Its main economic and technical benefits are as follows.
1. Improve the efficiency of mountain construction;
2. The inclined roadway transportation system is simplified, the rail transportation time of inclined roadway is reduced, and the pedestrian safety in inclined roadway is greatly improved.
3. The transportation link is optimized. Since it is not necessary to remove the hook, the entire inclined roadway transportation system only needs to be equipped with two signalmen, reducing the labor input.
4. The construction technology is simple, the equipment is easy to make, and the materials are easy to obtain. It is suitable for promotion and application in the construction of inclined roadway under the shaft. Especially, the inclined roadway with a length of more than 1000 m has obvious practical effect.
At present, there are many kinds of trams for ore transportation in domestic mines, and large and medium-sized mines tend to use bottom dump and bottom side dump trams for transportation. Compared with other types of tramcars, these two types of tramcars can realize continuous loading and unloading
Good morning, young friends! Next, the small editor is ready to explain the relevant contents of the single hydraulic prop for the small friends. The small friends are also deeply impressed with the single hydraulic prop. I still hope that this explanation will bring some gains to my friends1. For n
In order to make the hydraulic acrow props work stable, give full play to the efficiency of the equipment, and extend the service life, in addition to strictly complying with the operating procedures, it is necessary to strengthen daily maintenance.Precautions for maintenance and management of singl
