Description

Technical Field

The first anchor 1 and the second anchor 2 are respectively arranged on the first bank 13 and the second bank 14;

[0040] The first cable tower 3 and the second cable tower 4 are respectively arranged on the bank 13 and the bank 2, and are located between the first anchor 1 and the second anchor 2; one end of the load-bearing cable 5 is anchored to the first anchor 1, and the other end is anchored to the second anchor 2 through the first cable tower 3 and the second cable tower 4 in sequence; the overhead travelling vehicle device 6 is slidably arranged on the load-bearing cable 5; the traction device 7 comprises a traction drive mechanism 7.1 and a traction cable 7.2, the traction drive mechanism 7.1 is arranged on the bank 13, the traction cable 7.2 is wound around the traction drive mechanism 7.1, the first end of the traction cable 7.2 is connected to the first anchor 1 through the first anchor 1, the first cable tower 3 and the first end of the overhead travelling vehicle device 6, the second end of the traction cable 7.2 is connected to the second anchor 2 through the first anchor 1, the first cable tower 3, the second cable tower 4, the second anchor 2 and the second end of the overhead travelling vehicle device 6; the traction drive mechanism 7.1 can drive the overhead travelling vehicle device 6 to slide along the load-bearing cable 5 through the traction cable 7.2.
