The invention relates to the technical field of hoisting equipment, in particular to a tower crane climbing frame which comprises four main chord members, an upper cross beam, a lower cross beam and a jacking cross beam, the lower cross beam is connected with the four main chord members, the upper cross beam is connected with the four main chord members, and at least eight lifting oil cylinders are arranged on the lower cross beam. The lifting oil cylinders are evenly distributed at the four corners of the lower cross beam, the ends, away from the lower cross beam, of the lifting oil cylinders are connected with the jacking cross beam, the jacking cross beam is arranged on the side, away from the upper cross beam, of the lower cross beam, a plurality of first climbing claws are detachably arranged on the lower cross beam, and a plurality of second climbing claws are detachably arranged on the jacking cross beam. The lifting device has the beneficial effects that enough jacking force can be improved by adopting the at least eight lifting oil cylinders, and the multiple lifting oil cylinders are arranged close to the four main chord members correspondingly, so that bending stress borne by the climbing frame can be reduced, and the stability of the climbing frame of the super-tonnage tower crane in the climbing process can be improved.

    本发明涉及起重设备技术领域,尤其涉及一种塔机爬升架,包括四个主弦杆、上横梁、下横梁和顶升横梁,下横梁和四个主弦杆相连,上横梁和四个主弦杆相连,下横梁上至少设置有八个抬升油缸,多个抬升油缸均匀的分布在下横梁的四个边角处,抬升油缸远离下横梁的一端和顶升横梁相连,顶升横梁设置在下横梁远离上横梁的一侧,下横梁上可拆卸设置有多个第一爬爪,顶升横梁上可拆卸设置有多个第二爬爪。本发明的有益效果为:本发明通过采用至少八个抬升油缸能够提高足够的顶升力,且多个抬升油缸分别靠近四个主弦杆设置,能够减少爬升架受到的弯曲应力,有利于提高超大吨位塔式起重机的爬升架在爬升过程中的稳定性。
