The invention discloses an anti-collision device of a crane for building construction, relates to the technical field of crane anti-collision equipment. The problems that a fixed anti-collision structure is difficult to disassemble and replace, the later use is quite inconvenient, and the protection effect is poor are solved. The device comprises a supporting frame, and a protective sleeve mounting plate capable of sliding up and down is movably arranged on the outer side of a pull rope. According to the device, dismounting convenience can be increased through pre-fixing plates, the two pre-fixing plates are fixedly and symmetrically arranged at the front corner of the supporting frame through bolts before the crane is in use, and then a square plate at the bottom of an air bag support plate can be pushed from top to bottom to be embedded into an empty groove among the pre-fixing plates, a side clamping plate and a front clamping plate; and when the top of the front end of a telescopicframe collides, an air bag at the top of the air bag support plate firstly makes contact with external hard objects to play a preliminary buffering role, the air bag support plate can be forcefully pulled out upwards, the pre-fixing plates can be fixedly installed all the time, and therefore the replacement is more convenient in the later period.

    本发明公开了一种建筑施工用吊车的防撞装置,涉及吊车防撞设备技术领域,解决了固定式防撞结构难以进行拆卸更换,后期使用非常不便,防护作用较差的问题,包括支撑架;所述拉绳的外侧还活动设置有一个可上下滑动的保护套安装板。本装置通过预固定板可以增加拆卸的方便性,使用吊车前先将两个预固定板通过螺栓固定对称安装在支撑架的前方边角处,然后即可将气囊支撑板底部的方形板从上向下推动嵌入预固定板、侧夹板和前夹板之间的空槽中,当伸缩架的前端顶部发生碰撞时,气囊支撑板顶部的气囊会先接触外部硬物起到初步缓冲作用,而且气囊支撑板可用力向上抽出,预固定板可一直固定安装,因此在后期更换时也更加方便。
