The explosion-proof special type lead-acid battery rack rail car (permanent magnet frequency conversion integrated machine) is mainly composed of a cab, a drive unit, an electro-hydraulic control car, a lead-acid battery car, a pull rod, etc. It can run on special-shaped rail systems or ordinary rail systems.
Main components
drive unit
It is mainly composed 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: the traction force of a 22kW variable frequency speed control integrated machine is 60kN, and the traction force of a 45kW variable frequency speed control integrated machine is 135kN.
Mine flameproof and intrinsically safe lead-acid battery power charger
The charger is used to charge the lead-acid battery power supply device and can charge multiple boxes of batteries at the same time.
(1) The connection method between the mining flameproof charger and the battery adopts an integrated connection pin structure.
(2) Input AC voltage: 660V/1140V, DC output current: 10A〜100A, DC output voltage: 20V〜400V.
(3) The charger has a self-test function. Before the charger enters the working state, it can first perform a self-test. The self-test items include whether the polarity of the charging battery is reversed, whether the various parts of the main channel are normal, etc. The charger can enter the charging state only after the self-test is normal.
(4) It has a reverse battery connection protection function. The charging mode cannot be entered when the charging cable is connected in reverse.
(5) It has protection functions such as overcurrent, overload, short circuit and overtemperature (charging current is halved when the temperature is above 60°C).
(6) The charger has two charging working modes: constant current and constant voltage. (1 to 4 are constant current working modes, and 5 is constant voltage working mode)
(7) The charger can automatically complete the entire process from the start of charging to the end of charging without manual intervention. During each working process, the system can continuously detect the charging status: voltage, current, time and other set values. When one of the three reaches the set value, it will automatically switch to the next charging program until charging is completed. At the same time, the charger must also have the function of manual intervention during the charging process.
(8) The charger has an intelligent display function, and the display screen can display the charging status in real time, including: set current, real-time current, set voltage, real-time voltage, charging time, etc.
(9) It has a fault display function that can display the fault code or fault content on the display screen to facilitate fault finding and repair. The charger is used to charge the lead-acid battery power supply device and can charge multiple boxes of batteries at the same time. The length of the charging gun cable must be greater than 10m.
Product Advantages
Using batteries as the power source, low noise, no pollution, environmental protection, energy saving and safety;
●The locomotive is short in length and has its own power unit, enabling continuous transport without re-transfer and strong adaptability;
●The whole process is operated on track, which is highly safe;
●It can transport both materials and personnel;
●The locomotive can be controlled from the cab, by wireless remote control, or remotely from the dispatching room;
●The locomotive is equipped with a three-stage braking system and a safety brake car to realize backup safety braking for climbing, rolling back and downhill speeding.
According to the specific requirements of customers, various transport components can be selected, such as flatbed trucks (capable of transporting support materials, construction materials, belts, cables, small equipment and scattered spare parts); man-carriages (capable of transporting personnel underground, including 10-person and 15-person cars, which can transport 30 people at a time); ~45 people) etc.
