The explosion-proof lithium battery rack rail car (permanent magnet frequency conversion integrated machine) mainly consists of a cab, a lithium battery drive unit, a brake car, a pull rod, etc. It can run on special-shaped rail systems or ordinary rail systems.
Main components
Cab + electro-hydraulic control unit
Cab A is equipped with a control panel, operating status and road condition display screens, and a road condition detection robot. The latter monitors the locomotive's road conditions in real time and triggers an alarm, slows down, and automatically stops the vehicle when it detects an obstacle, ensuring driving safety. The electro-hydraulic control unit consists of a hydraulic control system and an electrical control system to achieve precise control and efficient operation of the locomotive.
Cab + drive unit
Cab B consists of the control room and drive unit, integrating a control box, operating status and road condition display screens, and a road condition detection robot. The road condition detection robot monitors the locomotive's road conditions in real time, issues an alarm when encountering obstacles, and automatically triggers deceleration or parking to ensure safe operation.
Dual drive cab
The integrated design of the cab, two drive units and electro -hydraulic control unit can effectively save space.
Dual-drive rail battery car
It is composed of 3 boxes of lithium-ion battery power supply + two drive units and is one of the basic components of the rack rail vehicle.
Lithium-ion battery power supply
The mining flameproof lithium-ion battery power supply device is composed of multiple explosion-proof lithium-ion battery power supplies.
The single lithium battery power supply is 320V and the rated capacity is not less than 228Ah.
A full charge can provide the locomotive with an empty-load range of 15 to 30km (the actual mileage is related to the lithium battery capacity, the number of drive parts, the load, the slope and the roadway conditions).
Frequency converter drive unit
It mainly consists of a variable frequency speed control integrated machine, a planetary reducer, a working brake (equipped with a built-in wet brake in the reducer and a disc brake acting on the drive wheel), a drive wheel, an encoder speed measuring device, a centrifugal speed limiting device, a drive bracket, a wheel swing frame, a rail wheel, a guide wheel, etc.
The driving force of a single drive unit is: equipped with two 22kW variable frequency speed control integrated machines, the traction force is 60kN; equipped with two 75kW variable frequency speed control integrated machines, the traction force is 135kN.
Lithium-ion battery power charger
Charger protection functions: overcurrent protection, input over/under voltage protection, overtemperature protection, short circuit protection, output over/under voltage protection, fault shutdown, emergency shutdown, lithium battery voltage detection and polarity protection.
Charger human-machine interface: intrinsically safe touch screen, parameter setting, status monitoring, data storage, fault recording, etc.
(a) Charging method: Programmable variable current intermittent rapid charging and manual control are used.
(b) The charger uses a fully digital display and has an excellent human-machine interface.
The human-machine interface is simple, easy to operate, and reliable.
The charger is equipped with a full digital display that can display charging parameters and status such as charging time, charging capacity, charging current, charging voltage, and internal temperature.
