Power car for narrow gauge electric motor car

Abstract

The invention relates to a power car for a narrow gauge electric motor car, which comprises a power car body, wherein, an electrical control system, a drive power supply and a braking device are arranged inside the car body; and two power steering frames are arranged at the bottom of the car body. The power car is characterized in that one of the power steering frames is arranged at the bottom of the car body under the drive power supply, and the other power steering frame is arranged between the bottom of the car body and the bottom of a carriage of an adjacent tow truck; the car body and the adjacent carriage are connected through an articulation device and a passing platform; the articulation device is arranged on a lower center plate of one of the power steering frames; the passing platform is arranged at the top of the articulation device; and the both sides between the car body and the adjacent carriage are connected with each other through a damper plate. The power car can be widely used in various occasions needing narrow gauge transportation, such as mine exploitation, tunnel excavation, light rails, subways, etc.

Description

technical field [0001] The invention relates to a moving car of an electric locomotive, in particular to a moving car of a narrow-gauge electric locomotive suitable for narrow-gauge transportation such as mining and tunnel excavation. Background technique [0002] The locomotives used in the existing mines are generally transported by narrow gauges with a gauge of 900mm, 720mm and 600mm. The maximum speed of the locomotives designed according to the national standard is 10.8km / h, while the speed of the existing locomotives is only 4-6km / h, the driving power of the locomotive and motor car uses a lead-acid battery, and the running part of the locomotive and motor car uses a steering gear. The motor car of the above-mentioned existing locomotive has the following problems: 1. The speed of the motor car of the locomotive is too slow, especially when the working face is located at a far place, it usually takes a long time to transport, which makes the underground auxiliary work...

AI Technical Summary

Problems solved by technology

The motor car of the above-mentioned existing locomotive has the following problems: 1. The speed of the motor car of the locomotive is too slow, especially when the working face is located at a far place, it usually takes a long time to transport, which makes the underground auxiliary work time increase and the production Reduced efficiency

2. Since the steering gear frame and the wheel set of the locomotive are rigid welded structures, the wheel set and the frame cannot be elastically displaced, resulting in a large wheel-rail angle of attack when the curve passes, so that the locomotive motor car often derails when turning , once the motor car of the locomotive derails, it will endanger the life safety of the workers

3. Since the frame of the steering gear and the wheel set are rigid welded structures, there is no shock absorbing device, and the disturbance from the rails is directly transmitted to the car body, causing greater vibration and noise in the car

4. The driving power of existing locomotives and motor vehicles uses lead-acid batteries, which are not only large in size, heavy in weight, and low in storage capacity, but also cannot be recharged as they are used, which also pollutes the environment
