[0028] The following is in conjunction with the appendix Figure 1 To be continued Figure 7The present invention will be described in detail with specific embodiments.

[0029] like Figures 1 to 7 As shown, the present invention provides a frequency converter handling device, including a first connecting plate 1. Four rollers 11 are fixedly installed on the lower surface of the first connecting plate 1. In this embodiment, the rollers 11 are universal wheels with brakes. A second connecting plate 2 is fixedly connected to the upper surface of the first connecting plate 1, and a pair of handles 21 are fixedly connected to the side wall of the second connecting plate 2. Pushing the handles 21 causes the first connecting plate 1 to move through the second connecting plate 2. During the movement of the first connecting plate 1, the rollers 11 rotate.

[0030] A vertically arranged hydraulic cylinder 3 is fixedly connected to the upper surface of the first connecting plate 1. There are four hydraulic cylinders 3. The piston rod of the hydraulic cylinder 3 is fixedly connected to a support platform 4. A support plate 5 is connected to the top of the support platform 4.

[0031] When the inverter 51 needs to be removed for transport, the maintenance personnel move the first connecting plate 1 to the bottom of the inverter 51. The piston rod of the hydraulic cylinder 3 extends, so that the upper surface of the support plate 5 abuts against the bottom of the inverter 51. The support plate 5 supports the inverter 51. The maintenance personnel release the fixing between the inverter 51 and the distribution cabinet. Then the piston rod of the hydraulic cylinder 3 retracts, and the support platform 4 and support plate 5 descend, lowering the position of the inverter 51. The maintenance personnel push the handle 21 to transport the inverter 51 to the maintenance area. The removal and transport of the inverter 51 is completed by moving the support plate 5, reducing the possibility of crushing accidents and ensuring the personal safety of the maintenance personnel.

[0032] The weighbridge body 6 is fixedly connected to the upper surface of the support platform 4. The support plate 5 is fixedly connected to the upper surface of the weighbridge body 6. The weighbridge body 6 is electrically connected to a display screen 61, which is used to display the weight value detected by the weighbridge body 6. The display screen 61 is fixedly connected to the side of the second connecting plate 2 near the support platform 4.

[0033] The support plate 5 supports the removed inverter 51, and the display screen 61 displays the weight value. Maintenance personnel can observe the weight value to understand the weight of the inverter 51 that needs to be moved.

[0034] A pair of protective components 7 are connected to the upper surface of the support plate 5. After the support plate 5 supports the inverter 51, the pair of protective components 7 are placed on both sides of the inverter 51 to protect both sides of the inverter 51 and increase the safety during the transportation of the inverter 51.

[0035] Each protective component 7 includes a vertically arranged first stop 71 and a second stop 72, with a third stop 73 connecting the first stop 71 and the second stop 72. The upper surface of the support plate 5 has a first sliding groove 74, and the lower surface of each first stop 71 is fixedly connected to a first slider 75, which is slidably connected to the first sliding groove 74. The side wall of the support plate 5 has a connecting groove 76, which communicates with the first sliding groove 74. Each first slider 75 is threadedly connected to a connecting bolt 77, which passes through the connecting groove 76 and is slidably connected to the connecting groove 76. Tightening the connecting bolt 77 causes it to abut tightly against the side wall of the support plate 5, fixing the position of the first slider 75.

[0036] After the support plate 5 supports the inverter 51, the first stop lever 71 is moved closer to the side of the inverter 51. The first stop lever 71 drives the second stop lever 72 and the third stop lever 73 to move closer to the side of the inverter 51. The third stop lever 73 is positioned close to the side wall of the inverter 51. After the position of the first stop lever 71 is adjusted, the connecting bolt 77 is tightened. The third stop lever 73 protects the inverter 51. The two third stop levers 73 block both sides of the inverter 51, increasing the safety during the transportation of the inverter 51.

[0037] The upper surface of the support plate 5 is also provided with a second sliding groove 78, and a second slider 79 is fixedly connected to the lower surface of each second stop 72. The second slider 79 is slidably connected to the second sliding groove 78. During the movement of the second stop 72, the second slider 79 slides in the second sliding groove 78, and the second slider 79 guides the movement of the second stop 72, increasing the stability of the second stop 72 during the movement.

[0038] The first stop 71 has an adjustment groove 711 on the side near the second stop 72, and the third stop 73 is slidably inserted into the adjustment groove 711. The side wall of the first stop 71 has several insertion holes 712 along the vertical direction, which communicate with the adjustment groove 711. The third stop 73 has an insertion groove 731 on the side near the insertion holes 712, and an insertion rod 8 is inserted into the insertion hole 712. The insertion rod 8 is inserted into the insertion groove 731, fixing the position of the third stop 73.

[0039] When the removed inverter 51 is at different heights, separate the plug rod 8 from the plug slot 731, then separate the plug rod 8 from the plug hole 712. Move the third stop rod 73 vertically to adjust its position and height, positioning it close to the middle of the inverter 51 to protect the inverter 51 near the center. After adjusting the position of the third stop rod 73, plug the plug rod 8 into the corresponding plug hole 712 again, then plug the plug rod 8 into the plug slot 731 to fix the position of the third stop rod 73.

[0040] The second stop 72 is provided with a T-slot 721, and a T-block 732 is fixedly connected to one end of the third stop 73 near the second stop 72. The T-block 732 is slidably connected to the T-slot 721. During the vertical movement of the third stop 73, the T-block 732 slides within the T-slot 721, and the cooperation between the T-block 732 and the T-slot 721 increases the stability during the movement of the third stop 73.

[0041] The implementation principle of the inverter handling device provided by this utility model is as follows: When the inverter 51 needs to be removed for handling, the maintenance personnel move the first connecting plate 1 to below the inverter 51, the piston rod of the hydraulic cylinder 3 extends, so that the upper surface of the support plate 5 abuts against the bottom of the inverter 51, and the support plate 5 supports the inverter 51. The maintenance personnel release the fixing between the inverter 51 and the distribution cabinet, and then the piston rod of the hydraulic cylinder 3 retracts, the support platform 4 and the support plate 5 descend, and the position height of the inverter 51 is lowered. The maintenance personnel connect the first slider 75 to the first slide groove 74, and the second slider 79 to the second slide groove 78, so that the third stop 73 is placed close to the inverter 51. After the connecting bolt 77 passes through the connecting groove 76, the connecting bolt 77 is threadedly connected to the first slider 75. The connecting bolt 77 is tightened to fix the position of the first slider 75. The maintenance personnel push the handle 21 to transport the inverter 51 to the maintenance area.
