Advantages Of Multi Power Electric Locomotive With Ore Battery Stringing

At present, the transportation and traction equipment widely used in mines in China are stringing narrow gauge locomotive and battery electric locomotive. The former is non explosion-proof type, which can only run in the roadway with stringing and without biogas.

The narrow gauge locomotive is generally explosion-proof special type with good safety performance, but the battery locomotive has high cost and short service life, which is only suitable for short-distance transportation in biogas tunnel. The development of the compound electric locomotive can improve the existing two-stage transportation mode. The double battery locomotive of mine battery stringing researched and developed by traction electric has filled in the domestic blank. The double power electric locomotive with mine battery stringing has a broad application prospect in China's mines.

(1) It can be used in the construction mine or production mine, vertical mine or adit mining, production level alternation, or extended driving of main roadway. It can not only undertake the main transport task, but also undertake the auxiliary transport task.

(2) It can reduce turnouts and overhead lines, simplify the transportation system, and solve the problem that the stringing locomotive directly enters the digging head and the mining area. When the power is cut off at the same time, it can still operate normally.

(3) The narrow gauge locomotive can pass through the loading point smoothly without detour, thus saving the loading time and engineering cost of another detour (generally 300m). At the same time, it is not afraid of coal dust and gas during loading, which can ensure safety. It is better for this kind of locomotive to pull the bottom unloading ore car through the unloading pit. It can use stringing to automatically charge the battery power supply device during operation, so that the locomotive does not need to change the power supply device or charge frequently in the charging ketone room, increasing the running time of the locomotive can improve the utilization coefficient of the locomotive, and the standby power supply device is omitted. The floating charging mode can also improve the service life of the battery.

(4) It is very suitable for flat hole mining with high biogas. In some mines, the use of 7-track narrow gauage locomotives in the past due to too much gas was banned due to insecurity. Using 8t battery electric locomotive, the transportation efficiency is low, the maintenance and management cost is high, which affects the production.This problem can be solved by the development of multiple power electric locomotive.

Considering the application of the battery locomotive in the mine, it is required that the locomotive be firm and reliable, easy to use and maintain, etc., Yutong traction electric design and development based on the current battery electric locomotive try to use the existing mature technology and components, shorten the development cycle and improve the working reliability.
