[0003] When installing large frequency converters, it usually requires manual labor (typically 6 people) to work together for more than 6 hours to remove the old frequency converter and install the new one. During the disassembly and assembly process, the production system often experiences large fluctuations, affecting output. At the same time, the slow disassembly and assembly of frequency converters and the long working hours make it difficult to work effectively, resulting in low efficiency in the disassembly and assembly of frequency converters.

[0004] Therefore, this utility model provides a portable inverter disassembly and assembly device. Utility Model Content

[0036] The method of using this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0037] like Figures 1 to 6 As shown, a portable inverter assembly / disassembly device includes: a base 1; and further includes:

[0038] Two uprights 2 are respectively vertically installed at both ends of the base 1;

[0039] A fixing rod 3 is horizontally installed across the top of the two uprights 2, and both ends of the fixing rod 3 are detachably installed to the top of the two uprights 2 respectively;

[0040] Two horizontal bars 4 are respectively installed at the top of the upright 2, and the horizontal bars 4 correspond one-to-one with the upright 2 and are perpendicular to each other;

[0041] Tripod 5 is movably mounted on the crossbar 4; tripod 5 uses a hoist to lift the frequency converter and connect and fix the frequency converter.

[0042] A crossarm support 6 is slidably mounted on the crossbar 4, and the crossarm support 6 is used to fix the frequency converter.

[0043] The crossarm support 6 includes:

[0044] The upper crossbeam 61 is horizontally slidably mounted on the crossbar 4;

[0045] The first threaded rod 62 is located at one end of the upper crossbeam 61;

[0046] The second threaded rod 63 is located at the top of the other end of the upper crossbeam 61;

[0047] The lower crossbeam 64 is movably connected at both ends to the bottom of the first threaded rod 62 and the bottom of the second screw, respectively.

[0048] The vertical height of the frequency converter can be adjusted by adjusting the distance between the lower crossarm 64 and the upper crossarm 61.

[0049] The crossarm support 6 can adjust the distance between the upper crossarm 61 and the lower crossarm 64 to raise or lower the inverter and adapt it to the inside of the electrical box. This allows the inverter to be quickly installed in the designated position inside the electrical box without the need for worker adjustment, saving labor intensity and installation time.

[0050] The crossarm support 6 is used to fix the frequency converter and adjust the vertical height of the frequency converter. The crossarm support 6 also drives the frequency converter to slide horizontally on the crossbar 4 and allows for the assembly and disassembly of the frequency converter.

[0051] The inverter is lifted by the base 1, crossbar 4, tripod and crossbeam support 6 and quickly installed inside the electrical box. The installation and removal of the inverter can usually be completed in just one hour, which greatly improves work efficiency and safety. In addition, the quick installation and removal of large inverters can reduce fluctuations in the production system, improve production stability and output.

[0052] At the same time, the entire device can be quickly disassembled and is easy to use.

[0053] One end of the crossbar 4 is vertically provided with a tube 41, and one end of the crossbar 4 is located in the middle of the tube 41. The tube 41 is connected to the top of the upright 2 by a fixing bolt 42. The other end of the crossbar 4 is vertically provided with a fixing screw 43. A fixing nut 44 is provided on the tail end of the fixing screw 43. A baffle 45 is provided on the fixing screw 43, and the baffle 45 is located between the crossbar 4 and the head end of the fixing screw 43.

[0054] By adjusting the fixing nut 44 on the fixing screw 43 and fixing one end of the crossbar 4 to the inner wall of the electrical box, the crossbar 4 is supported at both ends, thus allowing the frequency converter to be installed inside the electrical box. The baffle 45 is to prevent the crossbar 4 from slipping out of the electrical box, increase its contact area, and make the crossbar 4 more stable.

[0055] The tripod 5 includes:

[0056] Two isosceles triangles, 51, are arranged symmetrically to each other;

[0057] The reinforcing rod 52 has one end vertically mounted on the base of the isosceles triangle 51, and the other end mounted on the apex of the isosceles triangle 51.

[0058] The connecting rod 53 is connected at both ends to the apex of the two isosceles triangular blocks 51. The connecting rod 53 is used to connect to the hoist and lift the frequency converter.

[0059] During installation or disassembly, a hoist is required to connect the frequency converter so that it can be lifted and pushed into the electrical box for installation, or pulled out of the electrical box for disassembly.

[0060] The two ends of the upper crossarm 61 are movably connected to the tops of the first threaded rod 62 and the second threaded rod 63 via the first nut 65, and the two ends of the lower crossarm 64 are movably connected to the bottoms of the first threaded rod 62 and the second threaded rod 63 via the second nut 66. While fixing the upper crossarm 61 and the lower crossarm 64 with the first nut 65 and the second nut 66, the distance between the two crossarms can be adjusted, thereby adjusting the height of the frequency converter from the ground and adapting to the installation position inside the electrical box.

[0061] The fixing rod 3 has a first tube 31 and a second tube 32 vertically installed at both ends. The first tube 31 is connected to the tube 41 at the top of one of the uprights 2 by a first bolt 33, and the second tube 32 is connected to the tube 41 at the top of the other upright 2 by a second bolt 34. The first bolt 33 and the second bolt 34 are used to fix the fixing rod 3 and the upright 2.

[0062] The base 1 is connected to the bottom of the upright 2 at both ends by a third bolt 11 and a fourth bolt 12, respectively. The third bolt 11 and the fourth bolt 12 are used to fix the base 1 and the upright 2.

[0063] During installation: First, place the free end of the crossbar 4 inside the electrical box and fix it inside the box using the fixing screw 43 and fixing nut 44. Then, place the tripod 5 horizontally on the crossbar 4 and install the hoist on the tripod 5. Simultaneously, connect the hoist to the frequency converter. Then, pull the hoist to lift the frequency converter. Determine the height between the frequency converter and the ground based on its position inside the electrical box. Adjust the first nut 65 and the second nut 66 on the lower crossarm 64 to change the distance between the lower crossarm 64 and the upper crossarm 61. Then, fix the frequency converter on the lower crossarm 64 and remove the hoist and tripod 5 from the frequency converter. Finally, push the frequency converter inward into the electrical box to quickly install it inside. Then, remove the lower crossarm 64 from the frequency converter and the crossbar 4 inside the electrical box to complete the installation.

[0064] During disassembly, firstly, the free end of the crossbar 4 is inserted into the electrical box, and the free end of the crossbar 4 is fixed inside the electrical box by fixing screws 43 and fixing nuts 44. Adjust the first nut 65 and the second nut 66 on the lower crossarm 64 to change the distance between the lower crossarm 64 and the upper crossarm 61, and fix the lower crossarm 64 to the frequency converter. Then, remove the frequency converter from the electrical box, thereby pushing the electrical box outward. The upper crossarm 61 will slide outward on the crossbar 4. Subsequently, place the tripod 5 horizontally on the crossbar 4, and install the tool hoist on the tripod 5. Connect the hoist to the frequency converter, disconnect the connection between the lower crossarm 64 and the frequency converter, and finally, pull the hoist to lower the frequency converter, quickly completing the disassembly of the frequency converter.
