Herringbone tower crane anti-collision device with energy-dissipation function

Abstract

The invention discloses a herringbone tower crane anti-collision device with an energy-dissipation function. The herringbone tower crane anti-collision device comprises two support arms; each support arm comprises a channel steel bar and a buffer channel steel bar; the first end of each buffer channel steel bar is connected with the first end of the corresponding channel steel bar in a frictionally slidable manner; the second end of each channel steel bar is fixedly connected with a stable part of a building structure; the second ends of the two buffer channel steel bars are connected with each other through a rotatable hinge; and cushion rubber is fixedly connected with the second ends of the two buffer channel steel bars. In practical application, the herringbone tower crane anti-collision device with the energy-dissipation function is arranged between a protected object and a tower crane; when the big arm of the tower crane collides with the cushion rubber, the collision time can be prolonged by the cushion rubber, and the impact force can be reduced; meanwhile, a large amount of impact energy can be dissipated through frictional sliding of the buffer channel steel bars; and the impact force is reduced, and the bouncing effect of the support arms on the big arm of the tower crane is reduced, so that the influence of impact on the tower crane and the big arm of the tower crane is reduced.

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 collisions between tower cranes and old buildings, and between tower cranes and tower cranes occur from time to time. In order to reduce the damage to the tower crane and the building caused by the collision, a limit device is generally installed on the tower crane, but this kind of limit device often does not work well in the case of a power outage or strong wind. Summary of the invention [0003] The design objective of the present invention is to provide an anti-collision device for a herringbone tower c...
