1. A C-arm X-ray apparatus, comprising:
a C-arm translation assembly, a support column, a base, a counterweight, and an adjustment device, wherein
one end of the support column is connected to the base, and the other end of the support column is slidably connected to the C-arm translation assembly;
the counterweight is slidably connected to the base; and
the adjustment device is connected to the counterweight, and configured to drive the counterweight to move by a preset distance in a direction opposite to a first direction in the case that the C-arm translation assembly moves in the first direction, such that a gravity center of the C-arm X-ray apparatus remains at a preset position; wherein the adjustment device comprises: a follower, a driver and a pusher; wherein the follower is fixed on a side, facing towards the base, of the C-arm translation assembly; the driver is movably connected to the follower; the pusher is movably connected to the driver; and the driver is configured to transmit a movement distance of the follower to the pusher, and the pusher is configured to push the counterweight to move based on the movement distance.
