what’s a mining overhead trolley locomotive :Electric trolley locomotive generally refers to the traction equipment of rail transportation, and is the “locomotive” of rail vehicles. It is powered by high-voltage cables and uses electric motors to provide power to drive the wheels to rotate. Therefore, its traction force is not only limited by the power of the traction motor, but also affected by the friction coefficient between the wheel and the rail surface. In addition, the slope of the transportation track also has a great influence on its transportation capacity. Generally, the slope is required to be 3‰, and the local slope cannot exceed 30‰

Structures

The mechanical parts include frame, wheel set, reduction box, etc.

The electrical part includes driver controller, pantograph, traction motor and etc

Working principle

After the high-voltage alternating current is stepped down and rectified by the rectifier cabinet, the negative electrode is connected to the track, and the positive electrode is connected to the overhead wire. The pantograph on the locomotive is connected to the overhead line, and the current is introduced into the car, and then enters the DC traction motor through the automatic switch, controller and resistance box to drive the motor to run. The motor drives the wheels to rotate through the gear transmission device, thereby driving the train to run. The current from the motor flows back to the converter through the track. The speed regulation mode is divided into resistance speed regulation, chopper speed regulation and frequency conversion speed regulation.

Advantages

it has the advantages of low cost in the later stage and convenient maintenance.

Raw materials

The Locomotive is use high-quality steel plates and the weight meets the national standard requirements.

Strict assembly technology ensures that the locomotive leather is durable and reliable.

Special rust removal process on the surface plus multi-layer anti-corrosion coating, more anti-corrosion, suitable for high-corrosion and high-humidity environment in underground.

Locomotive motor

40 years of manufacturing experience has created a powerful traction motor, Durable with low failure rate and longer life, which provides a powerful power guarantee for the harsh mining environment. Supporting more than 20 locomotive manufacturers, including famous foreign brands, domestic CRRC, XEMC Company and Sunward Intelligent Company

Motor Technolgy

40 years of motor manufacturing and production experience

The motor armature adopts argon arc welding process, which greatly improves the temperature rise compared with traditional soldering, and the motor is more durable.

The insulation material adopts the F or H level, the quality is guaranteed.Two vacuum pressure dipping to ensure complete penetration of the insulating paint, more moisture proof and pressure resistance.

Motor test

The motor has to go through many inspection procedures before leaving the factory, and each motor has to be carried out with load running experiments.

Explosion-proof motors are carried out with water pressure test. All the test of motor is to ensure that can adapt to harsh working conditions.

Gearbox adjustment

Our locomotive requires the gear anastomosis surface to reach more than 80%, far exceeding the standard.

More efficient transmission, lower noise and longer gear life.

Factory test 1

Before running the locomotive, carry out position debugging, lighting test, gear and brake adjustment ect.

To ensure the normal operation of the locomotives

Factory test 2

1.Carry out a tensile test before leaving the factory to ensure the load performance of the locomotive meets the standard. Our design standards generally exceed the national standard by 10%-20%.

2. Carry out different type running tests before leaving the factory to ensure the performance and normal operation of the whole locomotive. It can adapt to various harsh conditions under simulated working conditions.

Locomotive Controller

Three controller methods could be choose:

1. the resistance speed control, to control the speed by changing the resistance value, the DC motor works, the commutation and speed regulation work with copper contact points, which has a short life and is easy to burn out.

2. Chopper speed control(IGBT control), stepless speed control, using chopper speed control technology, adding digital voltage display module and lighting power module, and the control switch of the electronic horn, the control switch of the front and rear lights are built in the chopper driver controller, which is easy to operate.

3. frequency conversion speed control(AC control), using frequency conversion control technology, control inverter circuit to convert DC power to AC power, control AC frequency conversion motor, the whole machine has no contacts, greatly extending the service life.

Locomotive Battery

There are three types of locomotive power supply options: ordinary lead-acid battery for locomotive, maintenance-free

battery for locomotive, and lithium battery for locomotive.

1. Ordinary lead-acid power supply needs to be charged with acid and water. The charging time is up to 8-10 hours, the

working time is 8 hours, and the service life is 1-2 years.

2. The maintenance-free power supply requires no water for charging, so the maintenance is simple. The charging time

also takes about 8-9 hours, the working time is 8 hours, and the service life is 1-2 years.

3. Lithium power supply does not need to add water and is maintenance-free. It can be fully charged in 2-3 hours, working

time is more than 8 hours, and the service life is 5-8 years.

Safety brake system

A variety of braking methods are available: pneumatic braking, hydraulic braking, electrical braking, and mechanical braking.

And according to the special mines of coal mines, gas breaker can be equipped as a optional.

Frame and suspension system

Professionally designed and adjusted frame ensures safe driving and avoids falling off rails. Suspension shock absorber system to make you enjoy the comfort of the car.

Customization and modification

We provide customized production of locomotives for many customers, such as: battery-trolley two use locomotive, special tools locomotives.

We could also provide South America Type locomotive. Electric locomotive modification is also provided, for example: locomotive control mode, ordinary resistance is changed to chopper speed(IGBT) or frequency conversion speed(AC control), ordinary mechanical brake is changed to hydraulic brake or air brake.

To improved the locomotive’s load capacity and to changed the locomotive’s ordinary lead-acid battery into a lithium battery.

Unmanned controll system

The electric locomotive unmanned driving system includes functions such as unmanned operation of locomotives, automatic ore loading, autonomous operation of variable speed cruise, unloading station material level and mine jam monitoring, safety emergency protection, chute and mine pit material level detection and other functions.

Cases 1

A good feedback of our lithium battery locomotive from a clients of Latin America

Case 2

In order to solve the exist problems of lead-acid batteries that need to add electrolyte regularly, maintenance is troublesome, a charging room is required for charging,a special person is required for charging, the charging time is long, the operating cost is high, the efficiency is low, and the environment is polluted.

More than 30 lead-acid battery electric locomotives in this large mining were changed into lithium battery electric locomotives, which improved the work enthusiasm and production efficiency of employees, reduced costs,and more environment-friendly.

Cases 3

The miningrock drill car designed by SunwardCo. has a small size and simple structure, so the space for placing the lithium battery on the body is very limited.

According to the limitation size, our company design a lithium power supply power plan, which perfectly solves the problem of lithium power supply space.
