Rail transfer car manufacturers to introduce you to the structure and principle application of KPD electric transfer car

Henan rail transfer car manufacturers said the frame system: the load-bearing capacity of the flat car, overload factor of 1:1.1; electric transfer car frame to ensure that the extra load does not deform. On the electric transfer car platform, located above the reducer motor with access holes, access hole strength to ensure that the load-bearing capacity is not affected; frame with lifting positions on both sides, easy to lift the flat car, lifting method to choose the unloading bolt lifting.

The raw material of the wheel is ZG55, the raw material of the bearing housing is ZG35, the raw material of the shaft is 45# and tempered, and the bearing through the spherical roller bearing seat stuck in the frame crossbeam under the positioning plate, each side with high-strength bolts fixed, positioning plate and bearing seat between the rubber pad to smooth the impact. One side of the bearing housing of the wheel pair has a suitable amount of clearance through the cover and boring cover, which can make the bearing move in the bearing housing axially in a trace, in order to solve the frame in the case of no-load, heavy load, the amount of elastic deformation and track transverse parallelism of the error, to ensure the smoothness of the work of the wheel on the track, and improve the service life of the vehicle. Insulation sleeve and insulated outer and inner pads are provided between the wheel and axle, and the insulating sleeve is made of high mechanical function insulating material.

The axis distance error is ±2.0mm; the parallelism of the two-wheel pairs axis is 3.0mm; the difference between the two-wheel pairs diagonal L1 and L2 is not more than 3.0mm; the two-wheel pairs bearing's the free end is installed on the same side of the vehicle. The operation mode is operated by a hand-operated push-button switch with the vehicle, and the operation box is equipped with emergency stop, travel and retreat pointing buttons. The single-phase low-voltage power supply electrical equipment includes the control box, step-down transformer, DC motor, ground control cabinet, etc.

Perfect Transfer Cart is equipped with sound and light alarm equipment on each flat car: two red sound and light warning lights are included, and the red sound and light warning lights are installed on both sides of the front of the car, and the alarm works at the same time when it is started. The motor is made of a DC motor of a famous brand, with protection grade IP44 and insulation grade B; the temperature rise of the motor and other components is not more than 80℃.
