Overview Of Mining Electric Vehicles

1. The role of  Mining electric locomotive: Mining electric locomotive are mainly used for long-distance transportation of underground transportation lanes and floors. It is equivalent to the electric locomotive head in railway transportation, pulling a train consisting of a mine car or a human car to walk on the track to complete the transportation of coal, vermiculite, materials, equipment and personnel. 20 tons of wire-type mining electric locomotive.

2. Principle and use conditions: The traction motor drives the wheel to rotate, and the locomotive runs on the track by the friction between the wheel and the rail surface. In this mode of operation, its traction is not only limited by the power of the traction motor, but also by the friction between the wheel and the rail surface. The slope of the locomotive transport can be limited, generally 3 ‰, and the local slope cannot exceed 30 ‰.

3. Form and classification of  Mining electric locomotive: According to the electric energy source, the electric motor vehicles are divided into two categories: mining DC motor vehicles and AC motor vehicles. DC motor vehicles are divided into DC wire-type electric vehicles (ZK type) and mining battery-type electric vehicles (XK type) according to different power supply modes. According to the adhesion quality of the motor car, the wire-type motor car has: 1.5t, 3t, 7t, 10t, 14t, 20t; the battery type has 2t, 2.5t, 8t, 12t. According to the gauge of the motor car, it is divided into three types according to the voltage level: 600mm, 762mm and 900mm. There are three types of wire-type electric vehicles: 100 (97)V, 250V and 550V; battery-type electric vehicles have 40/48V and 110/132V. Levels.
