The invention belongs to the technical field of tunnel turnover equipment, and particularly relates to a trackless portal crane for tunnel construction, which comprises two groups of upright posts, a cross beam and a hoisting mechanism, and is characterized in that the upright posts are vertically arranged at intervals; the two ends of the cross beam are connected to the stand columns correspondingly, and the lifting mechanism is arranged on the cross beam and used for lifting materials; the bottom of each stand column is further provided with a walking mechanism used for moving in the tunnel, each walking mechanism comprises two sets of driving wheels, a balance wheel, a mounting base and a position adjusting piece, the driving wheels are connected to the mounting bases at intervals, and the mounting bases are connected to the bottoms of the stand columns; the driving wheel is in transmission connection with the driving motor so as to move in the tunnel; the balance wheel is connected to the mounting base through a position adjusting piece, and the position adjusting piece is used for adjusting the position of the balance wheel so that the balance wheel can be in a tripod state relative to the driving wheel. Therefore, the technical problem that in the prior art, a trackless portal crane moves unstably and extends out is solved.
本发明属于隧道周转设备技术领域,具体涉及一种隧道施工用无轨门式起重机,包括立柱、横梁和起重机构,其中,立柱配设为两组,并竖直且间隔地设置;横梁的两端分别连接于立柱,起重机构设置于横梁上,以用于提升物料;每个立柱的底部还设有用于在隧道中移动的行走机构,行走机构包括驱动轮、平衡轮、安装座和调位件,驱动轮配设为两组并间隔地连接于安装座,安装座连接于立柱的底部;驱动轮传动连接于驱动电机,以能够在隧道中移动;平衡轮通过调位件连接于安装座,调位件用于调节平衡轮的位置,以使得平衡轮相对于驱动轮形成三足鼎立状态。由此,解决了现有技术中无轨门式起重机移动不平稳所延伸出来的技术问题。
