Detailed Description

The invention will be further explained with reference to the drawings:

as shown in fig. 1-2, the utility model discloses a cable switching device, which comprises an input joint 2, a middle frame 1 and an output joint 2, wherein a cable 4 enters from the input joint 2, extends into the output joint 3 after passing through the middle frame 1, and finally is led out from the output joint 3; the input connector 2 and the output connector 3 are respectively connected to two opposite sides of the middle frame 1, the input connector 2 can rotate around a first rotating shaft a, the output connector 3 can rotate around a second rotating shaft b, and the first rotating shaft a and the second rotating shaft b are arranged perpendicular to each other.

One end of a cable entering the input connector 2 is connected to a power source, the cable is connected into the input connector 2, led out from the output connector 3 through the middle frame 1 and connected to the operation and maintenance machine equipment, and the power is provided by the cable to supply power to the machine equipment for maintaining the wind power tower.

The device follows behind the machine equipment, is positioned closer to the equipment for use, and is followed by a trailing cable. When the device rises to the high position of the wind power tower along with the equipment, a cable which hangs down from the rear is very long, and the swinging and twisting are easy to occur. When the cable entering the input connector 2 swings, the input connector 2 is driven to rotate to counteract most of the swinging, so that the machine equipment is ensured not to be interfered excessively and to operate normally; when the cable is twisted, the output connector 3 rotates along with the cable, so that the twisting is counteracted, and the cable is prevented from being wound.
