The invention discloses a trackless measuring trolley for a suspended contact network. The invention belongs to the technical field of rail construction. The trolley comprises a lower supporting plate, and an upper supporting plate is connected to the upper portion of the lower supporting plate through a frame body. The vertical center of the bottom end of the upper supporting plate is connected with a plumb bob through a connecting rope; the left end and the right end of the lower supporting plate are rotationally connected with idler wheels through connecting shafts respectively, a laser range finder is installed on the upper supporting plate, the axis of the laser range finder is perpendicular to the axis of the plumb bob, and the frame body is composed of two sets of telescopic framessymmetrically arranged on the lower supporting plate. A threaded rod is in threaded connection with a rotating shaft, so a hinge frame composed of two hinge rods can ascend and descend under the rotation of the threaded rod, so that the height of the left side or the right side of the upper supporting plate is adjusted, a worker can conveniently and rapidly adjust whether the upper end face of theupper supporting plate is horizontal or not and whether the upper end face of the upper supporting plate is parallel to a rail or not, and the working efficiency of the worker is improved.
本发明公开了悬挂接触网无轨测量小车,属于轨道施工技术领域,包括下支撑板,所述下支撑板的上方通过架体连接有上支撑板,且上支撑板底端的竖直中心处通过连接绳连接有铅锤,所述下支撑板的左右两端分别通过连接轴转动连接有滚轮,所述上支撑板上安装有激光测距仪,且激光测距仪的轴线与所述铅锤的轴心线垂直,所述架体由两组对称设于下支撑板上的伸缩架构成。本发明通过螺纹杆与转轴之间的螺纹连接,使由两个铰接杆构成的铰接架可在螺纹杆的转动下实现升降,以此对上支撑板的左侧或右侧的高度进行调节,以方便工作人员对上支撑板上端面是否水平以及是否与轨道平行进行快速的调整,提高工作人员的工作效率。
