The invention discloses a movable rotating platform for steering of a tunnel construction vehicle, belongs to the technical field of tunnel engineering, and is used for solving the problems that an existing rotating platform is unstable in steering and inconvenient to run on an arc-shaped ground. Comprising a positioning mechanism, a moving mechanism and a telescopic mechanism, when the construction vehicle drives onto the rotating table, the position of a tire can be driven to the position right opposite to a positioning groove, a first servo electric cylinder contracts to drive a folding frame to be folded, then a supporting plate is driven to descend, when the supporting plate descends, the tire of the construction vehicle can be clamped into the positioning groove, and then the construction vehicle can be positioned on the rotating table; a third servo electric cylinder works, a crawler belt can be inclined under the action of a second hinge seat and a third hinge seat, and the crawler belt stops when the crawler belt is inclined to obtain the maximum complete contact area with the tunnel ground, so that the contact area of the crawler belt moving in the track can be greatly increased; and the moving stability of the crawler belt is greatly improved.

    本发明公开了一种用于隧道施工车辆转向的可移动式旋转平台,属于隧道工程技术领域,用于解决现有的旋转平台转向不稳定、不便于在弧形地面行驶的问题;包括定位机构、移动机构、伸缩机构;当施工车辆开上旋转台时,轮胎的位置将会开到与正对定位槽处,第一伺服电缸收缩带动折叠架进行折叠,进而带动支撑板进行下降,当支撑板进行下降时,施工车辆的轮胎将会卡进定位槽中,进而可使施工车辆在旋转台上进行定位,使车辆稳定准确掉头,使第三伺服电缸工作,在第二铰接座与第三铰接座的作用下可使履带进行倾斜,当履带倾斜得到能与隧道地面完全接触面积最大时停止,该方式可大大增加了履带在轨道内移动的接触面积,大大增加了履带移动的稳定性。
