The invention discloses a tunnel top maintenance device for tunnel construction. The tunnel top maintenance device comprises a fixed base, wherein a plurality of vertically-arranged fixed pipes are fixedly connected to the upper end of the fixed base. The tunnel top maintenance device is reasonable in structure, by arranging a lifting mechanism and a folding mechanism, an output shaft of a first power motor rotates, an inclined rod rotates, and thus a sliding rod drives a lifting rod to achieve lifting of a platform; by arranging the folding mechanism, a moving rod moves to drive a plurality of rotating plates to rotate, under the effect of the rotating plates, a second sleeve rotates, and thus the second sleeve drives a rolling wheel to be folded and placed; and by arranging a fixing mechanism, an output shaft of a second power motor rotates, a threaded rod is driven to rotate, a clamping plate moves, thus a maintenance tool is clamped, a cover plate is rotated to effectively fix the maintenance tool, and the situation that the maintenance tool falls off, and consequently the working efficiency is affected, and meanwhile, danger is further caused to workers on the ground is avoided.

    本发明公开了一种隧道施工用隧道顶部维修设备,包括固定底座,所述固定底座的上端固定连接有多个呈竖直设置的固定管。本发明结构合理,通过设置升降机构与折叠机构,使第一动力电机的输出轴转动,使得斜杆转动,从而使滑动杆带动升降杆实现对平台进行升降,通过设置折叠机构,使移动杆移动,带动多个转动板转动,在转动板的作用下,第二套管转动,从而实现第二套管带动滚轮进行折叠放置,通过设置固定机构,使第二动力电机的输出轴转动,驱动螺纹杆转动,使夹板移动,从而将维修工具夹紧,转动盖板实现对维修工具进行有效的固定,避免维修工具掉落,影响工作效率的同时还会对地面上的工作人员造成危险。
