The support frame 3 is equipped with a brush lightning protection structure 4. The brush lightning protection structure 4 is connected to the support frame 3 through a connecting rod 4-7. The brush lightning protection structure 4 is grounded, and the brush 4-1 therein is in contact with the wire rope to achieve lightning protection.
[0018] In this embodiment, the brushes maintain continuous contact with the wire rope, enabling continuous operation while the cableway is in operation, providing real-time lightning protection, and significantly improving safety.
[0019] See Figure 3As shown, the brush lightning protection structure 4 includes a brush 4-1, a mounting shaft 4-2, a brush sleeve 4-3, and a grounding wire 4-8. The brush 4-1 is fixed on the brush sleeve 4-3, and the brush sleeve 4-3 is fitted onto the mounting shaft 4-2. One end of the mounting shaft 4-2 is fixed and limited by a washer 4-4 and a nut 4-5, and the other end is fixedly connected to a retaining ring 4-6 for further limitation. A connecting rod 4-7 is also connected to the mounting shaft 4-2, which is used to connect to the support frame 3. The brush 4-1 maintains elastic contact with the cableway wire rope 2. The grounding wire 4-8 is connected to the mounting shaft 4-2, and the other end of the grounding wire 4-8 is connected to the earth grounding electrode. In this embodiment, the brush and brush sleeve are movably fitted onto the mounting shaft, allowing for rolling friction with the wire rope and reducing wear on the wire rope.
[0020] Preferably, the brush 4-1 is a conductive carbon brush or copper brush, which has good wear resistance and a long service life.
[0021] Preferably, the grounding wire 4-8 is a copper braided strip, with one end connected to the mounting shaft 4-2 and the other end connected to the earth grounding electrode.
[0022] See Figure 3 As shown, the guide adjustment structure 5 is located between the connecting rod 4-7 and the support frame 3, and is used to adjust the contact position between the brush 4-1 and the cableway wire rope 2.
[0023] The guiding adjustment structure 5 includes: an adjusting screw 5-1, a connecting block 5-6, and a limiting block 5-9; the adjusting screw 5-1 is screwed into the adjusting screw hole 5-2 on the support frame 3; the connecting block 5-6 is located on the upper end of the connecting rod 4-7; one end of the adjusting screw 5-1 is provided with a T-shaped head 5-7, which is adapted to fit into the stepped hole in the connecting block 5-6 and can move relative to it; the stepped hole is provided with a pressure block 5-8 for limiting; the limiting block 5-9 is fixed on the support frame 3 and is provided with a guide slide 5-11; the connecting block 5-6 is provided with a guide slider 5-10 that is slidably adapted to the guide slide 5-11; a locking nut 5-3 is screwed onto the adjusting screw 5-1; one end of the adjusting screw 5-1 is fixed with a handle 5-4 by a set screw 5-5.
