Cable irradiation equipment for rail transit vehicle

The invention discloses cable irradiation equipment for a rail transit vehicle, which comprises a rack, a rotary take-up and pay-off system, a rotary under-beam system, an electron accelerator and a rotary driving mechanism, and is characterized in that the rotary take-up and pay-off system and the rotary under-beam system are rotationally arranged on the rack and are driven by the rotary driving mechanism to rotate; the electron accelerator is arranged above the rotary under-beam system, and the cable is unwound by the rotary take-up and pay-off system, enters the rotary under-beam system and then is wound by the rotary take-up and pay-off system. By means of the structure of the rotary take-up and pay-off system and the rotary under-beam system, cable take-up and pay-off and 360-degree rotation of the under-beam cable are achieved, so that the irradiation doses borne by all the side faces of the cable under the beam of the electron accelerator are equal, and the irradiation uniformity of the cable is good.
