Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0035] A main controller fixing component 2, the main controller fixing component 2 is rotatably arranged on the main controller mounting frame 1, and the main controller fixing component 2 is used to limit and fix the main controller;

[0036] An intrinsically safe base plate 3, which is slidably disposed on the main controller mounting frame 1 and is used to protect the main controller;

[0037] The power supply base plate 4 is arranged on the upper end of the intrinsically safe base plate 3 and is used for installing a power supply;

[0038] The electrical component mounting frame 5 is rotatably arranged between the intrinsic safety base plate 3 and the power base plate 4 and is used for mounting electrical components.

[0039] Furthermore, in the above-mentioned multi-layer rotary measurement and control unit of the coal mining machine electrical control box, the main controller mounting frame 1 includes a mounting base plate 11, support columns 12 and a slide rail plate 13. The support columns 12 are fixed on the mounting base plate 11 in a rectangular distribution, and the slide rail plate 13 is fixed to the top of the support by bolts, thereby forming an independent space for the main controller installation position.

[0040] Furthermore, in the above-mentioned multi-layer rotary measurement and control unit of the coal mining machine electrical control box, a slide groove 131 is symmetrically arranged on the upper end surface of the slide rail plate 13, and a slide table 31 is symmetrically arranged on the bottom of the intrinsically safe bottom plate 3. The intrinsically safe bottom plate 3 is slidably arranged in the slide groove 131 on the slide rail plate 13 through the slide table 31, so that the intrinsically safe bottom plate 3 slides out along the slide groove 131 through the slide table 31, which is convenient for the installation of electrical components installed on the intrinsically safe plate.

[0041] Furthermore, in the above-mentioned multi-layer rotary measurement and control unit of the coal mining machine electrical control box, the main controller fixing assembly 2 includes a mounting platform 21, a pressure plate 22 and a limiting bolt 23. The mounting platform 21 is fixed to the mounting base plate 11 by bolts, and one end of the pressure plate 22 is rotatably and symmetrically installed at both ends of the mounting platform 21. The other end of the pressure plate 22 is threadedly engaged with the mounting base plate 11 through the limiting bolt 23, so that the pressure plate 22 rotates around the two ends of the mounting platform 21. The limiting bolt 23 is used to limit the pressure plate 22 to fix the main controller, and at the same time, the pressure plate 22 is used to limit the left and right movement of the main controller.

[0042] Furthermore, in the above-mentioned multi-layer rotary measurement and control unit of the coal mining machine electrical control box, the length of the mounting platform 21 matches the width of the main controller, and the length of the pressure plate 22 is longer than the length of the main controller, thereby effectively ensuring that the main controller is completely fixed by the main controller fixing assembly 2.

[0043] Furthermore, in the above-mentioned multi-layer rotary measurement and control unit of the coal mining machine electrical control box, the electrical component mounting frame 5 includes an electrical component mounting plate 51, a first rotating column 52, a second rotating column 53 and a limiting stud 6. The first rotating column 52 is arranged in a rectangular distribution on the intrinsically safe base plate 3, the second rotating column 53 is arranged on the first rotating column 52 and fixed to the power supply base plate 4 by bolts, the electrical component mounting plate 51 can be rotatably arranged on the first rotating column 52, the limiting stud 6 is arranged on the side of the intrinsically safe base plate 3 close to the electrical component mounting plate 51, and the electrical component mounting plate 51 is fixed to the limiting stud 6 by bolts, thereby effectively ensuring that the electrical component mounting plate 51 can be rotated when the bolts on the limiting stud 6 are removed to facilitate the removal of the electrical components.

[0044] Furthermore, in the above-mentioned multi-layer rotary measurement and control unit of the coal mining machine electrical control box, the size of the electrical component mounting plate 51 matches the size of the installed electrical components, so that it is suitable for electrical components of various sizes.

[0045] Furthermore, in the above-mentioned multi-layer rotary measurement and control unit of the coal mining machine electrical control box, a first stud 521 is arranged at the bottom of the first rotating column 52, the first stud 521 is threadedly engaged with the intrinsically safe bottom plate 3, a rotating groove 522 is arranged at the upper end of the first rotating column 52, the electrical component mounting plate 51 is sleeved with the rotating groove 522, and a threaded groove 523 is arranged in the middle of the upper end of the first rotating column 52, so that the electrical component mounting plate 51 can rotate while avoiding excessive rotation to cause the first stud 521 to loosen.

[0046] Furthermore, in the above-mentioned multi-layer rotary measurement and control unit of the coal mining machine electrical control box, a second stud 531 is provided at the bottom of the second rotating column 53 , and the second stud 531 is threadedly engaged with the thread groove 523 .

[0047] Specifically, when the main controller is to be repaired, the limit bolts 23 are first taken out, the pressure plate 22 is lifted, and the pressure plate 22 rotates around the two ends of the mounting platform 21. At this time, the pressure plate 22 releases the limit on the main controller, and the main controller is pulled out of the main controller mounting frame 1 for repair. After the repair is completed, the main controller is pushed back into the main controller mounting frame 1, and the pressure plate 22 is pressed down to press the two sides of the main controller. At the same time, the pressure plate 22 is limited and fixed by the limit bolts 23. When the electrical component is to be repaired or replaced, the intrinsically safe bottom plate 3 is now pulled out along the slide groove 131 through the slide table 31. After pulling it out, the bolts on the limit studs 6 on one side of the electrical component mounting plate 51 where the electrical component to be repaired or replaced is located are removed. At this time, the electrical component mounting plate 51 is rotated outward along the rotating groove 522. At this time, the electrical component is removed for repair or replacement.

[0048] In summary, compared with the prior art, the multi-layer rotary measurement and control unit of the coal mining machine electrical control box of the present invention has the following advantages and beneficial effects: the overall structure of the present invention is simple, and the main controller is fixed by a main controller fixing assembly. The main controller can be taken out without removing the electrical components installed on the upper end of the main controller, thereby facilitating the installation, debugging and maintenance of the main controller. The electrical components are installed through the electrical component mounting frame, thereby facilitating the independent installation, debugging and maintenance of each electrical component, effectively reducing the downtime of the coal mining machine and improving production efficiency.
