Abstract

The invention relates to a full alternative-current controlled mining electric-wheel dumper, belonging to the technical field of design and application of a mining electric-wheel dumper, which comprises a full alternative-current transmission system of the mining electric-wheel dumper, wherein the full alternative-current transmission system of the mining electric-wheel dumper is improved for realizing more optimal transmission control, comprises a main generator auxiliary winding for suppling power for a cooling system, and an auxiliary rectifier, a fan inverter A and a fan inverter B which are matched with the main generator auxiliary winding, and also comprises an alternative-current brake resistance cooling fan, a main cooling fan, a wheel motor A and a wheel motor B. According to the invention, the full alternative-current control of the mining electric-wheel dumper can be realized, so that the designs of parts easy to damage in the original system can be greatly reduced, the mining electric-wheel dumper can be ensured to safely and stably operate, the working condition requirement of long-term continuous operation in a mine can be favorably realized, and the fault rate of the mining electric-wheel dumper in the use process can be effectively reduced.

Description

technical field [0001] The invention relates to a fully AC-controlled electric-wheel mine dump truck, which belongs to the field of electric-wheel mine dump trucks. Background technique [0002] The electric wheel mining dump truck is a large-scale transportation equipment, which has the characteristics of large load capacity, high efficiency, low transportation cost and long service life. However, in the prior art in the art, electric wheel mining dump trucks have the following characteristics: [0003] (1) It adopts a complete DC control method, and the wheel motor and cooling fan are both DC motors; [0004] (2) The AC and DC coexistence control method is adopted, the wheel motor uses an AC motor, and the cooling fan uses a DC motor. [0005] The components such as contactors and carbon brushes used in the DC system need to be replaced regularly, which brings about frequent maintenance, high failure rate, low efficiency and other disadvantages, which greatly affects the...
