The invention discloses equipment for continuous recognition of voltage classes of multiple groups of cables and an application method of the equipment, and particularly relates to a device capable ofrealizing rapidly continuous recognition of voltage classes of cables. The device is simple and rapid and capable of saving labor force and simplifying detection flow. The technical scheme includes that a guide rod is sleeved with a sleeve block, a clamp plate is fixedly connected to the right side of the sleeve block, a movable plate is hinged to the front of the clamp plate, a side plate is fixedly connected to the upper portion of the left of a support plate, a drive motor is fixed to the upper portion of the side plate through a flange, a turn plate is fixedly connected to the end of an output shaft, the upper end of a connecting rod is rotationally connected to the eccentric point of the outer edge of the lateral side of the turn plate, and the sleeve block is rotationally connectedwith the lower end of the connecting rod; a first bevel gear is fixed to the lower portion of a driven shaft, a second bevel gear meshes with the lower portion of the first bevel gear and is fixed tothe upper end of the driven shaft, and a gear is fixedly connected to the lower portion of the driven shaft; a rack is engaged with the back of the gear, penetrates the side plate and the guide rod, and is fixed to a detection car, a detection barrel is fixed onto the detection car, and a plurality of pressure sensors are distributed uniformly in the detection barrel. The equipment and the application method thereof are applicable to the field of electrical equipment.
