[0026] Example 1

[0027] like Figure 1-4 As shown, a seated bearing 3 is fixedly connected to the inner surface of the U-shaped frame 1, a conveying roller 302 is rotatably connected inside the seated bearing 3, and a rubber sleeve 303 is nested on the outer surface of the conveying roller 302.

[0028] In this embodiment, the seated bearing 3 is securely mounted on the U-shaped frame 1 by bolts 301, providing stable support and a rotational base for the conveying roller 302. The outer surface of the conveying roller 302 is nested with a rubber sleeve 303. The rubber sleeve 303 has good wear resistance and a certain degree of elasticity, which can provide stable support and gentle friction when in contact with the bottom of the mining switch cabinet housing, preventing the housing from sliding or being damaged during the conveying process, and facilitating the loading and unloading of the switch cabinet.

[0029] like Figure 1-4 As shown, bolts 301 are fixedly connected to the outer surface of the bearing 3 with a seat. The bearing 3 with a seat is fixedly connected to the U-shaped frame 1 by bolts 301. Support legs 2 are fixedly connected to the lower surface of the U-shaped frame 1. A through groove is opened on the upper surface of the U-shaped frame 1. A mounting seat 4 is fixedly connected to the upper surface of the U-shaped frame 1. A limit seat 401 is fixedly connected to the upper surface of the mounting seat 4. A first limit rod 404 is slidably connected inside the limit seat 401. A push plate 403 is fixedly connected to one end of the first limit rod 404. A first hydraulic cylinder 402 is fixedly connected to the outer surface of the limit seat 401.

The output end of the second hydraulic cylinder 608 is fixedly connected to the lifting seat 606.

[0034] In this embodiment, the second hydraulic cylinder 608 can drive the lifting seat 606 to move up and down along the sliding seat 601, thereby realizing the lifting and lowering adjustment of the drilling mechanism 7. The sliding connection of the second limiting rod 607 in the sliding seat 601 guides the movement of the lifting seat 606, ensuring the stability of the lifting process of the drilling mechanism 7. It can flexibly adjust the contact position between the drill bit 702 and the outer shell according to the different thicknesses of the outer shell and the drilling requirements, thus improving the versatility and adaptability of the equipment.

[0036] In this embodiment, the telescopic connection structure of the sleeve rod 703 and the inner rod 704 allows the protective cover 705 to effectively block the flying debris generated during drilling. When the second hydraulic cylinder 608 drives the lifting seat 606 to descend, the position of the protective cover 705 is changed through the telescopic connection structure, protecting the safety of the equipment and operators. It also helps to maintain a clean working environment and improve the service life and work efficiency of the equipment.
