Electric Flat Car,Electric Rail Car,Trolley

Product Description:

Profile

Electric flat car is an electric rail transport vehicle.Also known as trolley, cross vehicle.It has the advantages of simple structure, convenient use, easy maintenance, large bearing capacity, less pollution and so on.Widely used in machinery manufacturing and metallurgy factory, as the workshop internal coordination crane transport heavy cross in. 

Technical Parameters

The most of electric flat car is reel power supply for electric flat car, with a cable reel 380V AC power supply.Cable reel for hysteresis coupling, ensure the uniform stress of the cable is not easy bad.The exchange of 380V to flatcar YZ metallurgy Lifting motor provides power, electric flat car operation.Flat car running cable reel automatic cable rolled up or release, by the reel power supply length effects, general maximum operating distance is less than 200m. The single-phase 36V (three-phase) low-voltage track power supply electric flat car, rail sliding contact line power supply.Ground step-down transformer control cabinet (three-phase AC single-phase) 380V buck to single phase (phase 36V), via rail sliding contact line is fed to a flat car, the car a step-up transformer for single phase (phase 380V) AC.For flat cars in single phase capacitor motor provides power (three YZ metallurgy Lifting motor).Because there is no cable, it is safe and reliable, not afraid of hot, not hit, do not prevent cross transport, easy to realize the remote control and automation, transportation arrangement with great convenience to the factory.But the track construction requirements higher, should ensure that the track insulation, over a certain distance running track should be added to copper compensation line.Running distance is longer also need to increase the number of voltage transformer.

The electric flat car starting through the track starting current is very large (up to 1000A), at the end of the track has a large voltage drop, caused by single phase capacitor motor starting difficulty, the single-phase  flatcar maximum tonnage is 50 tons, load 50 tons and above using three-phase 3

Structure

-General

The electric flat car mainly consist of frame, transmission device (active, passive wheel wheel), electrical control.

Frame with four longitudinal beams and a plurality of beams and decking plate welded into a frame structure, usually with large steel as frame longitudinal beam, bearing frame, take eight, uniform stress.Wheel-set on the shoulder pole bearing seat is connected with the frame by bolts, the structure effectively reduces the height of table.

Gear reducer cycloidal type gear reducer on the flat end, convenient assembly and maintenance, convenient refit.

Electric flat car and set up a connection hook, when necessary, can draw other cars or be towed.Flat car for lifting the lifting holes arranged on both sides.Mode of operation for the use of a hand held button box walking vehicle control.

-Wheel

The wheel and axle of the electric flat car is arranged between the inner and outer insulating sleeve and the insulating pad, the insulating sleeve with high mechanical properties of insulating materials made from nylon, wheel after insulation makes the electric flat car can use two tracks as a two conductor rail.Axle material for the 45 # steel quenched and tempered, wheel material using 55 high quality steel, surface quenching, bearings are double-row spherical roller bearings, can automatically compensate the deformation of frame error.

Wheel bearing seat through the pole mounted on the frame, each side with four fixing bolt, the structure effectively reduces the height, lateral stability, bearing capacity, stress of a frame beneficial.

-Transmission Device

The transmission form of the electric flat car as a V belt deceleration with a two gear reducer.The motor through a triangular V belt transmission two stage gear reducer, reducer high speed motor is fixed on the body side, by tension bolt and tension belt.

Speed reducer for flat car special axle-hung hardened-gear speed reducer, the output shaft is driving wheel axle, gear for hardened gear, has the advantages of small volume, large transmission power, good fatigue strength.Gear material pinion 40 Cr, 20Cr.Speed reducer and the driving wheel set is composed of a transmission device assembly.Through the pole bearing block is mounted on the frame, each side with four bolts to fix.

-Traction Hook

Electric flat car and set up a connection hook, when necessary, can draw other cars or be towed.Pay special attention to when the car is towed, be sure to lift the brake, to prevent gear or triangle V belt damage.And do not exceed the rated speed of flat, otherwise the motor for super rotation state which could damage.
