CJY7 Ton Mine Overwire Electric Locomotiveis powered by the power grid composed of rectifier cabinet and overhead line, and the traction motor provides power. Its purpose is to tow an unpowered rail vehicle running on the track, similar to a locomotive. It is generally used in mine transportation, hauling tramcar to transport materials or hauling people and vehicles to transport personnel. Although more upfront investment is required, long-term, long-distance transportation costs are lower.

7-ton overhead electric locomotive can reach 70 tons on the road surface with a slope of less than 3.

There are many models of overhead electric locomotives, and different models of overhead electric locomotives are suitable for different use requirements.

take the CJY10 as an example, a complete model code is CJY10/6GB.

CJY refers to the mining electric locomotive, in the case of CJL, it is a double cab.

The first number (10) represents the tonnage of the model. The main models are CJY1.5, CJY3, CJY6, CJY7, CJY10, CJY14, etc.

slash represents the gauge, generally 6, 7 and 9 represent 600mm, 762mm and 900mm respectively.

G refers to the steel wheel. At the same time, G also represents resistance speed regulation, GB is chopper speed regulation, and GP is frequency conversion speed regulation.

The main structure of the electric locomotive isFrame,Travel device,braking device,controller,Traction motor,Pantographand other equipment such as speakers.

Frame: The frame is divided into two parts: the cab and the body. The cab is the control center of the overhead electric locomotive, in which the driver controller, horn and direct transformer are installed. The car body is the main body of the overhead electric locomotive, which is equipped with walking device, braking device, traction motor and pantograph.

controller: The control core of the overhead electric locomotive, resistance speed regulation, chopper speed regulation and frequency conversion speed regulation.

Pantograph: The overhead electric locomotive obtains electric energy from the overhead line through the pantograph to supply energy for the electric locomotive. It is mainly composed of single-arm type and double-arm type. There are also pantographs of different materials to choose from.

Traction motor: The power source of overhead electric locomotive, there are two types of DC motor and AC motor.

In addition to different tonnage models, the overhead electric locomotive also has many configurations such as gauge, speed regulation mode, braking mode, working voltage, etc. to be selected. Because the power supply method of the overhead electric locomotive is that the pantograph contacts with the overhead line, it is easy to friction to generate electric sparks, so it cannot be applied to coal mines. In other mines with low gas concentration, safety protection should be done according to the relevant track.

speed control mode optional: There are three kinds of resistance speed regulation, chopper speed regulation and frequency conversion speed regulation. Resistance speed regulation is the most economical, simple principle and structure, easy to repair. Chopper speed regulation and frequency conversion speed regulation are stepless speed regulation, the control performance is better and more reliable, but there are certain requirements for repair personnel.

braking mode optional: air brake, hydraulic brake, mechanical brake three ways. Mechanical braking is the basic braking method and will be installed on all electric locomotives. Hydraulic brakes are mostly used for 3-5 tons of electric locomotives, and air brakes are mostly used for electric locomotives of 6 tons and above. In addition, electric braking can be selected as an auxiliary braking method.

working voltage: The common working voltage of electric locomotive is 250V or 550V.

support locomotive customization and modification: We can provide customers with customized production of locomotives, such as: wire storage battery dual-purpose power locomotives, special tool locomotives. It also provides electric locomotive transformation, for example, the locomotive control mode is changed from ordinary resistance to chopper speed regulation or frequency conversion speed regulation, ordinary mechanical brake is changed to hydraulic brake or air brake, and the locomotive load capacity is improved.
