[0057] In this embodiment, the installation and use process of the drilling device for the horizontal pipes in the coke oven basement is as follows:

[0058] 1. Pre-assemble the transverse tubes 8 according to the requirements of the drawings. In this embodiment, the transverse tubes to be processed are composed of two long transverse tubes 801 in the middle and two short transverse tubes 802 at both ends; the two ends of the pre-assembled transverse tubes 8 are respectively seated on the bracket seats 101 of the two transverse tube fixing brackets 1, and then the bracket pressure plates 102 are installed and tightened with bolts to prevent the transverse tubes 8 from rotating during the drilling process; in this embodiment, rubber pads are added to the contact parts between the transverse tube fixing brackets 1 and the transverse tubes 8 to prevent damage to the transverse tubes 8.

[0059] 2. Adjust the position of the horizontal guide rail 2 so that it maintains a set distance from the horizontal pipe 8 and allows the three drill bits to act vertically on the center line of the horizontal pipe 8.

[0060] 3. Assemble the drilling assembly; first, pass the coupling 302, two shaft bevel gears 304 and the intermediate gear plate 303 in the transmission mechanism through the intermediate protective cover 702, connect the two lower parts of the coupling 302 to the intermediate gear plate 303, make the shaft bevel gear 304 and the intermediate gear plate 303 mesh correctly, then weld the bottom plate to the bottom of the intermediate protective cover 702, and finally insert the intermediate drill bit 308 through the reserved hole on the bottom plate and connect it to the intermediate gear plate 303.

[0061] 4. Install the outer gear disc 307 and the shaft bevel gear 2 306 in the two outer protective covers 704 respectively, so that the shaft bevel gear 2 306 and the outer gear disc 307 are properly meshed, weld the bottom plate of the outer protective cover 704, and then install the outer drill bit 309, and then connect the two shaft bevel gears 2 306 and the two shaft bevel gears 1 304 through the adjustable connecting rod 305, adjust the length of the adjustable connecting rod 305, and tighten it with screws after adjusting it in place.

[0064] 7. After all installations are completed, the equipment should be debugged to ensure that the drilling components can move smoothly in the horizontal and vertical directions. After the equipment is debugged, the drilling operation can be carried out.

[0065] If the spacing between the prefabricated holes on the horizontal tube 8 is too small, the minimum length of the adjustable connecting rod 305 cannot meet the requirements, and the drilling can be carried out in a skipped sequence, that is, first process the three spaced holes (such as hole 1, hole 3, hole 5), and then process the adjacent holes (i.e. hole 2, hole 4, hole 6).
