Description

Technical Field

[0001] The utility model relates to the technical field of maintenance platforms, in particular to a frequency converter maintenance platform device. Background Art

[0002] The frequency converter is a power regulation device used to control the speed and output power of AC motors. It controls the motor by changing the power supply frequency and voltage, thereby adjusting its speed and output power, achieving energy saving, speed regulation, and reducing starting current. During the use of the frequency converter, various faults may occur, such as circuit board burnout, component damage, loose connection wires, etc., which require maintenance to repair the faults and ensure the normal operation of the equipment.

[0003] In the prior art, there is a patent with application number CN202321767631.7, which provides a frequency converter maintenance and testing platform, including a load-bearing base, a placement plate and an adjustment component. A placement plate is arranged above the load-bearing base, an adjustment component is arranged between the placement plate and the load-bearing base, and a clamping component is arranged on the top of the placement plate. When the staff needs to adjust the height of the placement plate, they can start the motor to rotate one of the pulleys, thereby driving the other pulley to rotate through the belt, so that the two worms rotate accordingly, so that the worm drives the turbine to rotate, and at the same time, the threaded structure inside the turbine is used to drive the screw to drive the placement plate to move upward, so that the height of the placement plate can be adjusted to adapt to the different operating habits and heights of the staff, increasing the applicability of the device in practice.

[0004] However, the above patent still has the following deficiencies during use:

[0005] When the inverter is installed on the platform, the maintenance angle of the inverter cannot be flexibly adjusted during the maintenance process. In the actual inverter maintenance process, it is usually necessary to disassemble, wire, and replace components of the inverter. The fixed angle of the inverter may increase the difficulty of observation and operation for maintenance personnel, thereby reducing the work efficiency of inverter maintenance.
