The invention provides a rail inspection trolley which comprises a beam body and a plurality of transverse tensioning mechanisms arranged at the two ends of the beam body. Each transverse tensioning mechanism comprises a base body, a first wheel set, a spring and a guide shaft, and each base body comprises a base and a sliding block in sliding connection with the base. The first wheel set comprises a first support connected with the bottom of the sliding block, a first rolling wheel installed on the first support and a first tensioning wheel. The guide shaft is fixed to the base, the top of the sliding block is connected with the guide shaft in a sliding and sleeving mode, and the spring is connected with the base and the sliding block and drives the sliding block in the tensioning direction of the first tensioning wheel so that the first tensioning wheel can tension the inner side face of the steel rail. According to the invention, the sliding block is arranged and is in sliding connection with the base, and the guide shaft is arranged to guide the sliding of the sliding block, so that the transverse telescopic movement of the first tensioning wheel is guided, and the stability of tensioning the steel rail by the first tensioning wheel is improved, so that the measurement posture of the rail detection trolley is reliably maintained, and the measurement precision of the rail detection trolley is improved.

    本发明提供一种轨检小车,包括梁体、及设于梁体两端的多个横向张紧机构,横向张紧机构包括基体、第一轮组、弹簧及导轴,基体包括基座及与基座滑动连接的滑块,第一轮组包括与滑块的底部连接的第一支座、安装于第一支座上的第一滚轮及第一张紧轮,导轴固定于基座上,滑块的顶部与导轴滑动套接,弹簧连接基座和滑块并朝第一张紧轮的张紧方向驱使所述滑块,以使第一张紧轮张紧钢轨内侧面。本发明通过设置滑块并使滑块与基座滑动连接,并设置导轴对滑块的滑动进行导向,以对第一张紧轮的横向伸缩运动进行导向,提高第一张紧轮张紧钢轨的稳定性,从而可靠的保持轨检小车的测量姿态,进而提高轨检小车的测量精度。
