It should be understood that the present disclosure can have various changes in different embodiments without departing from the scope of the present disclosure, and the descriptions and drawings therein are essentially for illustrative purposes rather than for limiting the present disclosure.

[0052] In the following description of different exemplary embodiments of the present disclosure, reference is made to the accompanying drawings, which form a part of the present disclosure and in which different exemplary structures, systems and steps that can implement multiple aspects of the present disclosure are shown by way of example. It should be understood that other specific schemes of components, structures, exemplary devices, systems and steps can be used, and structural and functional modifications can be made without departing from the scope of the present disclosure. Moreover, although the terms "above", "between", "within", etc. may be used in this specification to describe different exemplary features and elements of the present disclosure, these terms are used herein only for convenience, such as according to the direction of the examples described in the accompanying drawings. Nothing in this specification should be construed as requiring a specific three-dimensional orientation of the structure to fall within the scope of the present disclosure.

[0053] See also Figure 1 , which representatively shows the structural schematic diagram of the mining electric locomotive group proposed in the present disclosure. In this exemplary embodiment, the mining electric locomotive group proposed in the present disclosure is described by taking the locomotive equipment applied to mountain mines as an example. It is easy for those skilled in the art to understand that in order to apply the relevant design of the present disclosure to other types of locomotive equipment, various modifications, additions, substitutions, deletions or other changes are made to the specific embodiments described below, and these changes are still within the scope of the principle of the mining electric locomotive group proposed in the present disclosure.

[0054] like Figure 1 As shown, in one embodiment of the present disclosure, the mining electric locomotive group proposed in the present disclosure includes a control electric locomotive 100, two dump trucks 200, an electric transmission system and a power reconnection device. Figures 2 to 5 , Figure 2 , an enlarged view of controlling the electric locomotive 100 is representatively shown;

[0055] Figure 3 A schematic diagram of the plan layout of controlling the electric locomotive 100 is representatively shown in FIG. Figure 4 An enlarged view of a dump truck 200 is representatively shown in FIG. Figure 5 A schematic plan view of a dump truck 200 is representatively shown in FIG. 1 and FIG. 2 are views showing a schematic plan view of a dump truck 200. The structure, connection mode and functional relationship of the main components of the mining electric locomotive group proposed in the present disclosure will be described in detail below in conjunction with the above drawings.

[0056] like Figures 1 to 5 As shown, in one embodiment of the present disclosure, the control electric locomotive 100 is provided with a control system, a first traction motor and a first bogie 110. The control system can control the first traction motor. The first bogie 110 is a powered bogie, and the first bogie 110 is driven by the first traction motor. The dump truck 200 is provided with a second traction motor and a second bogie 210, and the second bogie 210 is a powered bogie, and the second bogie 210 is driven by the second traction motor. The electric transmission system is provided in the control electric locomotive 100, and the electric transmission system is connected to the second traction motor via the traction motor large line connector. The control electric locomotive 100 can receive power from the pantograph and supply power to the second traction motor via the electric transmission system. The power coupling device is connected to the control electric locomotive 100 and the dump truck 200, and the power coupling device includes a coupling connector, and the coupling connector connects the control system, the electric transmission system and the second traction motor. The control system can transmit a control signal to the second traction motor via the reconnection connector, and the electric transmission system can transmit electric energy to the second traction motor via the reconnection connector, that is, the control electric locomotive 100 supplies power to the second traction motors of the two dump trucks 200 and implements traction braking control through the power reconnection device. Accordingly, the present disclosure can realize the use of the control electric locomotive 100 to supply power to the dump truck 200 and implement traction (and may also include braking) control, that is, the grid-side circuit of the electric locomotive group adopts a centralized current collection and conversion, and decentralized traction power supply mode, and realizes the control instructions of the electric locomotive group are uniformly issued by the control electric locomotive 100 and executed by the dump truck 200. Through the above design, the present disclosure proposes a new type of electric locomotive group consisting of a control electric locomotive 100 and several powered dump trucks 200, integrating the control system and the electric transmission system into the control electric locomotive 100, and configuring the dump truck 200 with a powered bogie, thereby realizing that the control electric locomotive 100 and the dump truck 200 can both exert traction (for example, the electric air valve can be used to achieve the same action time of the control electric locomotive 100 and the dump truck 200, ensuring that both exert traction at the same time), thereby improving the climbing ability of the mining electric locomotive group. At the same time, since the present disclosure only uses one control electric locomotive 100, compared with the existing solution of using two or more locomotives, the present disclosure can significantly reduce the cost of the mining electric locomotive group, and has better economy.

[0057] like Figure 1As shown, in one embodiment of the present disclosure, the present disclosure is described by taking the example that a mining electric locomotive group includes a control electric locomotive 100 and two dump trucks 200. Accordingly, taking the axle weight of the mining electric locomotive group as 30t as an example, the starting traction force of the mining electric locomotive group can reach 1200kN, and the 40‰ slope can tow a weight of not less than 2500t, and the dump truck 200 can carry a load of not less than 45t. In other embodiments, the mining electric locomotive group proposed in the present disclosure may also include one, three or more dump trucks 200. The number of dump trucks 200 can be flexibly selected according to actual needs. In other words, in various possible embodiments consistent with the design concept of the present disclosure, the mining electric locomotive group proposed in the present disclosure includes a control electric locomotive 100 and at least one dump truck 200.

[0058] like Figure 2 As shown, in one embodiment of the present disclosure, the control electric locomotive 100 is provided with a pantograph, and the pantograph is, for example, arranged on the roof of the control electric locomotive 100, and the pantograph can cooperate with the pantograph network to receive the pantograph network power supply. On this basis, the pantograph can be a dual-current pantograph, and the control electric locomotive 100 can be compatible with the dual-current DC1.5kV and DC3kV voltage systems. Specifically, the pantograph can include a central pantograph 1201 and a side pantograph 1202. Moreover, the mining electric locomotive group can be suitable for DC pantograph network power supply.

Among them, the control electric locomotive 100 and the dump truck 200 can be provided with braking components such as basic braking devices. On this basis, the mining electric locomotive group proposed in the present disclosure can have a regenerative braking function, thereby enabling the mining electric locomotive group to recover the electric energy generated by the reverse rotation of the first traction motor and the second traction motor during the braking process and feed it back to the power grid. Through the above design, the present disclosure can further reduce energy consumption and improve economy.
