Supporting platform for frequency converter assembly

Abstract

The invention relates to the technical field of frequency converters, in particular to a supporting platform for frequency converter assembly. The supporting platform for frequency converter assemblycomprises two first supporting rods; one side of each third supporting rod is provided with a second threaded rod; the two ends of each second threaded rod are rotationally connected with the corresponding third supporting rod; a driven chain wheel is connected to the lower part of the outer side of each second threaded rod in a sleeving manner; a threaded sliding block is connected to outer sidethreads of each second threaded rod; the upper surface of each threaded sliding block is fixedly provided with a second supporting rod; a connection rod is connected between the two third supporting rods; the lower end of a rotary shaft is rotationally connected with the connection rod; each driving chain wheel is in transmission connection with the corresponding driven chain wheel through a chain; and a first supporting plate is connected to the upper ends of the two second supporting rods together. The supporting platform provided by the invention can perform omnidirectional regulation on aheight, an inclination and a rotation angle of a frequency converter in a groove, enables frequency converter assembly to be more efficient and rapider, saves the manpower and material resources, improves the assembly efficiency and lowers the loss of an enterprise.

Description

technical field [0001] The invention relates to the technical field of frequency converters, in particular to a supporting platform for assembling frequency converters. Background technique [0002] Inverter (Variable-frequency Drive, VFD) is a power control device that uses frequency conversion technology and microelectronics technology to control AC motors by changing the frequency of the motor's operating power supply. The frequency converter is mainly composed of rectification (AC to DC), filter, inverter (DC to AC), braking unit, drive unit, detection unit, micro-processing unit, etc. The frequency converter adjusts the voltage and frequency of the output power supply by switching off the internal IGBT, and provides the required power supply voltage according to the actual needs of the motor, thereby achieving the purpose of energy saving and speed regulation. In addition, the frequency converter has many protection functions , such as overcurrent, overvoltage, overloa...

AI Technical Summary

Problems solved by technology

[0003] However, when the existing frequency converters are assembled, they are all assembled on a fixed platform. The fixed platform cannot change the height and angle. There are many inconveniences in the assembly of the frequency converter. On the one hand, it is a great waste of manpower and material resources. Seriously affect the assembly efficiency of the frequency converter, which will cause greater losses to the factory. In view of the above defects, we propose a support platform for frequency converter assembly
