The invention discloses a tunnel construction trolley. The trolley structurally comprises a supporting frame, a jack, side fences and a top table; the jack is arranged inside the supporting frame; theside fences are welded to the left and right sides of the supporting frame; the bottom of the top table is embedded in the upper surface of the supporting frame. The tunnel construction trolley provided by the invention has the beneficial effects that a rotating belt drives a positioning ring to rotate to enable supporting legs to rotate; the trolley can turn as required during moving; when the trolley is fixed, a thread pushes a push rod downwards to move a moving block to cling to the ground, and thus the stability of the trolley is improved, shaking of the trolley during tunnel construction is avoided, and the situation that a tunnel cannot be accurately machined is avoided; a sliding plate is fixed through a clamping plate, rotating balls move downwards along with the moving block, moving wheels are tightly attached to the ground of the tunnel downwards, and harm to safety of workers is avoided.
本发明公开了一种隧道施工台车,其结构包括支撑架、千斤顶、侧栏、顶台,千斤顶安装在支撑架内侧,侧栏通过焊接连接于支撑架左右两侧,顶台底部嵌固于支撑架上表面,本发明的有益效果在于:通转带带动定位环转动使得支撑脚转动,利于台车移动时根据需求而转弯,当台车固定时螺纹向下推动推杆使移动块移动至紧贴地面,从而提高台车的稳定性,避免台车在对隧道进行施工时摇晃,以免导致无法对隧道精确加工,卡板将滑板进行固定,并通过转珠跟随移动块向下移动,使移动轮向下紧贴隧道地面,以免对工作人员的安全造成危害。
