Strip mine electric shovel cable protection device

The invention relates to the technical field of strip mine electric shovels, in particular to a strip mine electric shovel cable protection device which comprises a fixing component. Comprising a first half part, a second half part arranged on the first half part, a supporting assembly arranged between the first half part and the second half part, a clamping assembly arranged on the supporting assembly, a damping assembly arranged between the clamping assembly and the first half part, and a driving assembly arranged on the supporting assembly. A plurality of groups of protection devices are connected through hinge rods, so that the device can be assembled into a protection assembly adaptive to the length of a cable and can be bent along with the cable at the same time, thereby being suitable for the use scene of the cable; and the driving assembly drives the supporting assembly to rotate, so that the clamping assembly slides on the supporting assembly, the clamping assembly can clamp cables of different sizes
