Adjustable lofting device suitable for accurate lofting of track laying base mark
The invention relates to the technical field of track laying base mark lofting, and discloses an adjustable lofting device suitable for track laying base mark accurate lofting. Comprising a fan-shaped plate, and the horizontal angle of the fan-shaped plate is adjusted by rotating a threaded sleeve or an adjusting shaft; a transverse gradienter and a longitudinal gradienter which are transversely arranged are arranged at the top of the sector plate, the inner end of the moving rod is arranged in the guide rail groove and connected with a lead screw, and a nut is connected to the lead screw; the nut is rotated to drive the moving rod to move in the guide rail groove and drive the swing rod to swing, so that the hinge sleeve drives the marking end plane to move. The horizontal position of a sector plate is controlled in a high-precision mode through three threaded sleeves and an adjusting shaft in cooperation with a transverse gradienter and a longitudinal gradienter, and a nut is used for driving a movable rod to drive a swing rod to control a lofting rod and a prism to move front, back, left and right for precise positioning. Therefore, a base mark for track laying can reach an accurate and rapid lofting position without re-leveling, and the lofting process can be completed at one time without gradual approaching.
本发明涉及铺轨基标放样的技术领域，公开了适用于铺轨基标精准放样的可调式放样器；包括扇形板，通过转动螺纹套筒或调节轴，调节扇形板的水平角度；扇形板的顶部设有横向布置的横向水平仪以及纵向水平仪，移动杆的内端置于导轨槽中，且连接有丝杆，丝杆上连接有螺母；通过转动螺母，驱动移动杆在导轨槽中移动，带动摆动杆摆动，以使铰接套筒带动标记端平面移动；通过三个螺纹套筒以及调节轴再配合横向水平仪以及纵向水平仪高精度控制扇形板的水平位置，利用螺母驱动移动杆进而带动摆动杆控制放样杆以及棱镜前后左右移动精准定位，以使铺轨的基标达到精确、快速放样位置而无需重新调平，可使放样过程一次完成，无需逐渐趋近。
