The invention discloses an anti-collision device for limiting the work zone of a tower crane. The anti-collision device is characterized by comprising an upper stop block, a lower stop block, an upper support, a lower support, a slew support and a high-strength bolt, wherein the upper stop block is arranged at the lower part of the upper support; the lower stop block is arranged at the upper part of the lower support; the slewing support is horizontally arranged; the mount ring of the slewing support is connected and fixed through the high-strength bolt, the lower support and the lower stop block; the movable ring of the slewing support is connected and fixed through the high-strength bolt, the upper support and the upper block. According to the anti-collision device, no limiting steel structure element needs to be welded on the upper and lower support of the tower crane; the mounting is extremely convenient; the processing cost is low; the anti-collision device works together with the original slewing limiting device of the tower crane and the effect is ideal.
