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...

Abstract

The invention discloses an anti-collision device with an energy consumption function for a herringbone tower crane, which comprises two supporting arms and a buffer rubber, wherein each supporting arm comprises a steel channel and a buffer steel channel; the first ends of the buffer steel channels are connected to the first ends of the steel channels in a frictional slide mode; the second ends of the steel channels are fixedly connected to the stable position of a building structure; the second ends of the two buffer steel channels are connected through a rotary louver; and the buffer rubber is fixedly connected to the second ends of the two buffer steel channels. In the actual application, the anti-collision device with the energy consumption function for the herringbone tower crane is installed between a protected object and a tower crane; when the large arm of the tower crane collides with the buffer rubber, the buffer rubber can prolong the collision time and reduce impact force; and simultaneously, the buffer steel channels consume a large amount of impact energy through frictional slide, can further prolong the collision time, reduce the impact force and lighten the rebound of the supporting arms on the large arm of the tower crane, thereby reducing the influence of collision on the tower crane and the large arm of the tower crane.

Description

technical field [0001] The invention relates to a tower crane anti-collision device, in particular to a herringbone tower crane anti-collision device with energy consumption function. Background technique [0002] Tower cranes are mainly used for vertical and horizontal transportation of materials and installation of building components in house construction. At present, there are more and more new construction, reconstruction and expansion projects in densely built areas, and collision accidents between tower cranes and old buildings, tower cranes and tower cranes occur from time to time. In order to reduce the damage caused by the collision to both the tower crane and the building, a limiter is generally installed on the tower crane, but this limiter often does not work well in the case of power failure or strong wind. Contents of the invention [0003] The design purpose of the present invention is to provide a herringbone tower crane anti-collision device with energy ...
