[0002] The explosion-proof electric control box for mines is suitable for use in coal mines and other environments with explosive gases (methane mixtures) in the surrounding medium. It is used in control systems of coal mine loaders, warehouse clearing machines, conveying pumps, shotcrete machines and centrifuges with an AC 50Hz and a voltage of up to 1140V. It can also be used for the operation and stop of automatic control systems in other production links of coal mines.

[0003] After searching, the applicant found that a Chinese patent disclosed "a flameproof electric control box for mining", and its publication (announcement) number is "CN 220341799 U". This patent mainly provides a foldable placement table on one side of the distribution box door. After the maintenance personnel come, they open the box door and inspect the internal parts. During the inspection, the placement table can be rotated outward and then rotated again toward the distribution box so that the placement table is located in front of them for placing tool boxes and disassembled parts, which brings convenience to the maintenance personnel. However, the placement table is installed on the outside of the electric control box, which increases the space occupied by the electric control box and is easily damaged when moved. It is impossible to further limit the rolling parts, which easily causes the parts to roll and fall, resulting in the loss of parts. For this reason, we propose an flameproof electric control box for coal mining machines. Utility Model Content

[0036] Working principle:

[0037] First, open the sealing door 12, then rotate the tool box 21 clockwise along the rotating shaft, so that the tool box 21 is parallel to the bottom wall of the electric control compartment 13, then the side sealing plate 26 can be moved to the right, thereby driving the anti-slip plate 28 to move to the right, until the anti-slip plate 28 contacts the anti-slip block 27, then the side sealing plate 26 can be rotated clockwise, so that the side sealing plate 26 is placed on the right side of the tool bench 2, and then the tools can be placed inside the first tool compartment 22. After removing the parts from the electric control box 11, the replacement sealing plate 25 can be pushed to move toward the first tool compartment 22, thereby opening the second tool compartment 23, and then the parts can be placed. Place it inside the second tool compartment 23, and then move the replacement sealing plate 25 to the left again to seal the second tool compartment 23. When the maintenance is completed, use the replacement sealing plate 25 and the side sealing plate 26 to seal the first tool compartment 22 and the second tool compartment 23, and rotate the tool box 21 counterclockwise so that the tool box 21 and the bottom wall of the electric control compartment 13 are in a vertical state. Then the buckle frame 32 can be rotated clockwise along the installation axis 31, so that the buckle frame 32 fixes the tool box 21, and then move the limiting plate 34 into the fixing hole to further limit the position of the tool box 21. At this point, the entire workflow is completed.
