The invention discloses a telescopic crane capable of preventing a steel rope from falling off. The telescopic crane comprises a base, an anti-falling mechanism is arranged on the base, and the anti-falling mechanism comprises a support arranged on the upper side of the base. Through mutual cooperation of an electric push rod and a winding wheel, cargos are hoisted and moved, the telescopic crane can automatically trigger the anti-falling function when the steel rope is broken, induction fan blades are driven to rotate through the falling air flow of a carrying box, a safety air bag is inflated through a reciprocating motion structure, and therefore cargoes are protected through the bulged safety air bag, in the falling process, the carrying box can give out alarm sound so as to remind pedestrians on the lower side to pay attention to hide, safety of the pedestrians is protected, a powerful suction cup is ejected to a moving box through elastic potential energy of a spring, so that the carrying box can be fixed when the steel rope is broken, the carrying box is prevented from hitting the pedestrians, the crane further has a moving alarm function, early warning is conducted on the pedestrians on the lower side when the carrying box moves, and the pedestrians are reminded to pay attention to high-altitude falling objects and keep away from a construction area.

    本发明公开了一种防止钢绳脱落可伸缩的起重机,包括底座,底座上设有防坠落机构,防坠落机构包括设置在底座上侧的支架,本发明利用电动推杆和绕线轮相互配合,来实现对货物起重并将货物移动,本发明能够在钢丝绳断裂时自动触发防坠落功能,利用载物箱下落的风流带动感应扇叶转动,并利用一组往复运动结构对安全气囊进行充气,从而利用鼓起的安全气囊保护货物,并且,在下落过程中,载物箱还能发出警报声,提醒下侧行人注意躲避,保护行人安全,本发明还能利用弹簧弹性势能,将强力吸盘弹射到移动箱上,从而在钢丝绳断裂时也能将载物箱固定,防止载物箱砸到行人,本发明还具备移动警报功能,在载物箱移动时,对下侧行人进行预警,提醒行人注意高空落物,远离施工区域。
