The invention belongs to the technical field of track detection vehicles, and particularly relates to a left-hand thread limiting steel rail center detection split trolley which comprises a bottom plate, four first needle bearings are movably connected to the bottom plate in an equidistant rectangular mode, and sliding grooves are symmetrically formed in the two sides of the top end of the bottom plate; the two screw rod seats are mounted at the tops of the sliding grooves respectively, the screw rod seats are connected with threaded rods in a penetrating mode, the threaded rods can rotate in penetrating parts of the screw rod seats, threads on the threaded rods on the two sides of the threaded rods are arranged in opposite directions, and the direction of the sliding grooves is the same as that of the threaded rods; the two sliding blocks are arranged on the threaded rods on the two sides of the threaded rod base in a penetrating mode respectively, and the threaded rods are matched with the penetrating portions of the sliding blocks through threads. According to the left-hand thread limiting steel rail center detection split trolley, the bearings on the two sides can be driven to move synchronously by rotating the threaded rod, so that the vertical center of the prism coincides with the center of the steel rail.

    本发明公开的属于轨道检测车技术领域,具体为反螺纹限位钢轨中心检测分体小车,其包括:底板,等距矩形的活动连接有四个第一滚针轴承,所述底板的顶端两侧对称开设有滑槽;两个螺杆座,分别安装在所述滑槽的顶部,所述螺杆座贯穿连接有螺纹杆,所述螺纹杆可在所述螺杆座的贯穿部内转动,所述螺纹座两侧的螺纹杆上的螺纹呈反向设置,所述滑槽方向与所述螺纹杆方向相同;两个滑块,分别贯穿设置于所述螺杆座两侧的螺纹杆上,所述螺纹杆与所述滑块的贯穿部通过螺纹配合。该反螺纹限位钢轨中心检测分体小车,能够通过旋转螺纹杆,带动两侧的轴承同步移动,使棱镜的竖向中心与钢轨的中心重合。
