Electric contact net and storage battery set dual-power steel rail milling-grinding machine

Abstract

An electric contact net and storage battery pack dual-power steel rail milling-grinding machine is disclosed and comprises a power vehicle providing power needed by vehicle operation and travelling and an operation vehicle provided with a milling-grinding operation device. The power vehicle is provided with a storage battery chamber and a traction electrical cabinet chamber, the storage battery chamber is internally provided with a storage battery, and the traction electrical cabinet chamber is internally provided with an auxiliary current transforming cabinet, an auxiliary power supply cabinet and a storage battery managing cabinet; the output end of the auxiliary current transforming cabinet is connected to the input end of the auxiliary power supply cabinet, the auxiliary power supply cabinet supplies power to the milling-grinding operation device, an on-vehicle auxiliary device and a battery charger, and the battery charger supplies power to the traction storage battery; the storage battery managing cabinet comprises a breaker, a charging module and a direct current parallel-connection assembly and is used for protecting the storage battery and controlling charging and discharging of the storage battery; and the storage battery can temporarily supply power to the power vehicle and the operation vehicle. The electric contact net and storage battery pack dual-power steel rail milling-grinding machine can be suitable for operation in closed environments such as subways, safe and stable operation of the vehicles are ensured, vibration is small, and the milling-grinding cutting effect is excellent.

Description

technical field [0001] The invention relates to the field of railway maintenance, in particular to a dual-power rail milling vehicle for an electric catenary and a battery pack. Background technique [0002] The rail milling and grinding car is an important intelligent equipment for rail maintenance. After the rail is put into use, the surface will gradually have defects such as deformation and microcracks, and after deterioration, defects such as fat edges and peeling will form. After 3-9 months of use, the newly opened lines will produce damage such as wave wear and fish scales. This will aggravate the vibration of the train and the track, cause damage to components, and have a significant adverse effect on the safety and comfort of track operation. [0003] Scientific maintenance of rails will effectively ensure the safe and economical operation of railways. Regular rail maintenance for heavy-duty railways can increase the life of rails from 400 million tons to 2.2 billi...

AI Technical Summary

Problems solved by technology

[0005] However, it has relatively prominent disadvantages: 1. It needs low noise and low pollution discharge when operating in a closed environment such as the subway, while using an internal combustion engine as the driving power will generate a lot of noise and smoke; Medium and low vibration or even no vibration is required, while using an internal combustion engine as the driving power will generate vibration, which will affect the effect of rail milling and grinding

[0006] Therefore, the rail milling and grinding car with the internal combustion engine as the driving force cannot meet the above requirements.
