An air compressor is a device used to compress gas. The structure of an air compressor is similar to that of a water pump. Most air compressors are reciprocating piston type, with rotating blades or rotating screws. In today's industry, air compressors are increasingly used in harsh environments and inconvenient conditions such as mines or the wild. However, most existing air compressors are fixed in a certain place and are inconvenient to move. In addition, unstable input voltage is often encountered in the wild and mines.

In addition, the transformer epoxy resin coil was heavy and required the cooperation of multiple people for installation or disassembly, which was time-consuming, labor-intensive and labor-intensive. As a result, the production efficiency of the dry-type transformer epoxy resin coil was low and there were many deficiencies.

Furthermore, as shown in FIG. 12 , a third side disassembly component 8 is also included, which is used to first break open the two ends of the outer mold 14 and then remove the outer mold 14 from the epoxy resin product 10 . The third side disassembly component 8 is arranged on a side of the front panel 15 close to the mold 1 .

Furthermore, since the outer mold 14 is clamped on the outside of the epoxy resin product 10, the two ends of the outer mold 14 are first broken apart, and then the outer mold 14 is removed from one side to achieve disassembly.

Further, as shown in FIG12 , the third side disassembly assembly 8 includes:

A pipe rack 81, wherein one end of the pipe rack 81 facing the mold 1 is in a shape with an inwardly turned edge, and the pipe rack 81 is filled with fluid;

Mold disassembly steps:

After the mold 1 filled with epoxy resin is cooled for a predetermined time, it is transported to a predetermined position by the second transport assembly 91;

The first moving assembly 6 drives the sixth guiding assembly 67 to guide the base 11 and make the base 11 stop at a predetermined position;

The transport assembly 93 moves to the predetermined position just above the mold 1, and the main power gear 24 rotates to drive the upper disassembly assembly 2, the first side disassembly assembly 3, and the second side disassembly assembly 5 synchronously, so that the tensioning screw 17 is screwed out of the base 11;

The clamping plate 18 is loosened, and the multiple bolts 19 on the front panel 15 are rotated to be separated from the epoxy resin product 10, and the transport assembly 93 transports the connected inner mold 13, the annular sealing plate 12, the fixing bracket 16, the fixing plate 23, and the tightening screw 17 to the first conveying assembly 9 and puts them down;

The third side disassembly assembly 8 moves to grab the outer mold 14 and moves it to the third conveying assembly 92 to release and detach from the outer mold 14;

The front panel 15 mounted on the base 11 and the epoxy resin product 10 mounted on the front panel 15 are transported to the next station by the second transport assembly 91, and the epoxy resin product 10 is taken away.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
