[0015] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation methods of the present invention are now described with reference to the accompanying drawings.

[0016] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0017] As used in this application and the claims, unless the context clearly indicates otherwise, the words "a," "an," "an," and / or "the" are not intended to refer to the singular but may include the plural. Generally speaking, the terms "comprises" and "include" only indicate the inclusion of the steps and elements specifically identified, and these steps and elements do not constitute an exclusive list. A method or apparatus may also include other steps or elements.

[0018] Without the aid of a turning device, manual labor is impossible to perform the flipping and installation. Using manual labor alone would create safety hazards and compromise product quality. The reactor being installed weighs 300 kg, and manual labor is not feasible to flip the inverter to install the reactor. Installing the inverter from the bottom would pose a serious safety hazard, compromise product quality, and waste labor time.

[0019] Therefore, a more efficient inverter flipping device is provided.

[0020] like Figure 1-6 As shown, a frequency converter flipping device includes:

[0021] The support frame 101 includes a bottom frame 1011 and two longitudinal frames 1012 , wherein each of the longitudinal frames has at least one guide limit rod 1013 and a lead screw 1014 .

[0022] The turning frame 102 includes at least one inverter fixing arm 1021 .

[0023] The flipping drive mechanism 103 includes: a flipping fixed frame 1033 of the guide limit rod 1013 and the lead screw 1014 passing through the longitudinal frame on one side, a gearbox 1031 installed on the flipping fixed frame, and a flip hand wheel 1032 and a flipping drive shaft 1034 connected to the gearbox 1031; wherein, the flipping drive shaft 1034 is fixedly connected to the flip frame 102, the flip hand wheel 1032 rotates to drive the gearbox 1031 and then drives the flipping drive shaft 1034 to rotate, and the flipping drive shaft 1034 drives the flip frame 102 to flip.

[0024] Lifting drive mechanism: a lifting and fixing frame 1041 of the guide limit rod 1013 and the lead screw 1014 passing through the longitudinal frame on the other side, a lifting hand wheel installed on the lifting and fixing frame 1041, the lifting hand wheel is connected to and drives the lifting chain 1042, and a matching rotating shaft installed on the lifting and fixing frame 1041, the matching rotating shaft is also connected to the flip frame 102; wherein, the lifting hand wheel rotates to drive the lifting chain 1042 and then drives the gear matching with the lifting chain 1042, and then drives the lifting and fixing frame 1041 to rise and fall through the combination of the lead screw engaged with the gear.

[0025] In one embodiment, the two longitudinal frames are fixedly connected via a crossbeam 1015 .

[0026] In one embodiment, a moving wheel 1016 is installed at the bottom of the bottom frame 1011 .

[0027] In one embodiment, the turning frame 102 is equipped with a counterweight 1022 .

[0028] In one embodiment, the lifting and fixing frame 1041 is installed with a positioning block 1035 and a positioning pin 1036 .

[0029] In one embodiment, the flip frame 102 has a socket 1023 , and the socket 1023 is used to fix the flip frame 102 in conjunction with the positioning block 1035 and the positioning pin 1036 .

[0030] In one embodiment, a fixing hole 1024 is provided on the inverter fixing arm 1021 for fixing the inverter 200 with a fixing assembly.

[0031] Specifically, the tilting frame can be rotated to a horizontal position and pushed onto the inverter body. The fastening points of the box's lifting beam and the tilting frame must be aligned and tightened. Finally, the rotating wheels of the tilting device must be locked. The assembler must manually crank the lifting handwheel to raise the box, then manually crank the tilting platform to flip the box 180°, with the reactor facing upward. The positioning pins must be inserted to lock the box to prevent it from tilting. When removing and installing the reactor, one person can stand on a ladder and operate an overhead crane to coordinate the operation. After the work is completed, the box must be flipped back to its original position. The wooden pier must be placed at the load-bearing position. The tilting frame must be manually cranked onto the pier, the screws removed, and the tilting device removed.
