When the current collecting trolley follows the moving component of the tire-type gantry crane, a large number of sensors are used to traction protect the current collecting trolley to prevent the moving component of the tire-type gantry crane from pulling the current collecting trolley out of the tire-type gantry crane bracket, so that the current collecting trolley can provide stable power supply to the tire-type gantry crane. For example, a tire crane current collecting trolley traction device with Chinese patent application number CN202320706940.7 includes an openable and closable switch ring, the switch ring includes a fixed rod fixed on the current collecting trolley, and a rotating rod rotatably connected to the current collecting trolley; the switch ring is opened and closed by rotating the rotating rod; a traction ring, the traction ring is sleeved on the switch ring to tow the current collecting trolley; a first contact plate is fixed on the rotating rod, and a second contact plate is provided on the tire crane bracket. When the first contact plate conflicts with the second contact plate, the first contact plate and the rotating rod rotate to drive the switch ring to open, so that the traction ring is separated from the switch ring.
