In a preferred embodiment, the upper block outer wall is provided with a groove.

Through the technical scheme, the overall weight of the upper stop block is reduced.

In a preferred embodiment, the lower stop block is of an L-shaped structure, and reinforcing ribs are uniformly arranged on two sides of the lower stop block.

Through the technical scheme, the mechanical strength of the lower stop block is improved.

In a preferred embodiment, the lower and upper stops are each cast from high manganese steel.

Through the technical scheme, the steel wire rope has higher strength and longer service life.

In a preferred embodiment, a thread groove is formed on one side of each of the lower stop block and the upper stop block.

Through above-mentioned technical scheme, be convenient for install convenient to detach through the thread groove.

In summary, due to the adoption of the technical scheme, the beneficial effects of the utility model are as follows: the utility model provides a tower crane rotation anti-collision buffer device, which aims to carry out steering limit on a tower crane and improve the safety of the tower crane.

Through with lower dog fixed mounting on the lower gyration lower support of tower crane, with last dog fixed mounting in tower crane gyration upper support, the contained angle between upper dog and the lower dog is the allowable maximum rotation range of tower crane, makes the tower crane before the big arm of gyration bumps, and upper dog contact telescopic link reaches slow stop state through the rebound force of spring, avoids bumping to take place.
