Embodiment Construction
[0011] see figure 1 As shown, the herringbone tower crane anti-collision device 1 with energy dissipation function of the present invention mainly includes a buffer rubber 10 and two support arms 20 .
[0012] The support arm 20 is composed of a channel steel 21 and a buffer channel steel 22. The first end 211 of the channel steel 21 and the first end 221 of the buffer channel steel 22 are placed back to back (that is, the webs of the two are stacked on each other), and the cooperation figure 2 As shown, a notch 30 is opened in the overlapping range of the channel steel 21 and the buffer channel steel 22, and the channel steel 21 and the buffer channel steel 22 are connected by a plurality of bolts 40 in the notch 30. When the support arm 20 is subjected to When colliding, the buffer channel steel 22 can slide in the notch 30 through friction. The two support arms 20 are connected by a rotating louver 60 , and the two sides of the rotating louver 60 are respectively welded a...
