Description

Technical Field

[0001] The utility model relates to the technical field of slag pan cars, in particular to a frequency conversion control device for slag pan cars. Background Art

[0002] The slag pan car operates by reciprocating between the rail gauges, with one end performing a tank hoisting operation and the other end performing a slag receiving operation. The control method is to operate the forward and reverse buttons through the contactor on the slag pan car control device. Before the slag receiving operation, the slag pan car needs to be frequently operated to align and then receive the slag. There are some defects in the actual use of the slag pan car control device.

[0003] When the slag truck control device is used, it can only realize a single control function. Since the motor runs fast and is frequently started by inching, the starting current of the motor always runs at six times the rated current of the motor. On average, one motor will burn out and need to be replaced every week, which will increase the cost of motor overhaul, increase the labor intensity of employees and affect the slag receiving operation; secondly, when the slag truck control device is running, the electronic components inside it suffer serious heat loss and are very prone to burning. In addition, the components on the device are often not easy to disassemble and maintain independently, which makes the device difficult to repair and replace, and affects the service life of the device.
