The lower surface of the support rod 4 is fixedly connected with a clamping block 41, and the lower surface of the clamping block 41 is provided with a clamping groove 411. When the overhead crane 1 is stopped for maintenance, the clamping groove 411 is clamped with the track 11.
[0033] A rotating assembly 5 is provided between the connecting rod 2 and the overhead travelling crane 1. When the overhead travelling crane 1 needs to move, the rotating assembly 5 drives the connecting rod 2 and the connecting frame 21 to rotate upward, and the connecting frame 21 drives the warning sign 3 and the support rod 4 to rotate upward, so that the support rod 4 is separated from the track 11. When the overhead travelling crane 1 needs to stop for maintenance, the rotating assembly 5 drives the connecting rod 2 and the connecting frame 21 to rotate downward, and the connecting frame 21 drives the warning sign 3 and the support rod 4 to rotate downward, so that the clamping block 41 is clamped with the track 11, and the support rod 4 supports the warning sign 3, thereby increasing the stability of the connecting rod 2 and the connecting frame 21 when supporting the warning sign 3. The clamping groove 411 is clamped with the track 11, increasing the contact area between the clamping block 41 and the track 11, and increasing the stability of the clamping block 41 and the track 11.
