The anti-derailment traveling crane comprises a vertical plate arranged on the inner side of a traveling wheel of the traveling crane, a side rolling wheel and a lower rolling wheel, the side rolling wheel and the lower rolling wheel are arranged on the vertical plate, and the tread of the side rolling wheel makes contact with the side portion of a track and can roll along the side portion of the track. The tread of the lower roller is in contact with the bottom surface of the side part of the track and can roll along the bottom surface of the side part of the track; the side rollers and the lower rollers are arranged on the vertical plates, the lower rollers are additionally arranged on the bottom surfaces of the side parts of the rails on the premise that the side rollers ensure that the travelling crane turns on one side, and when the travelling crane travels downhill or the left and right of the bottom plate are uneven, the lower rollers are additionally arranged on the bottom surfaces of the side parts of the rails to avoid the situation that the travelling crane flies off the rails due to inertia. The lower rollers arranged at the bottoms of the side parts of the rails can prevent the travelling crane from being separated from the bottom surfaces of the rails and limit the travelling crane in the direction perpendicular to the rails, so that the running stability of the travelling crane is ensured.

    本发明公开了一种行车防脱轨装置及其防脱轨行车,包括用于设置在行车行走轮内侧的立板以及设置在所述立板上的侧滚轮和下滚轮,所述侧滚轮的胎面与轨道的侧部接触并可沿轨道侧部滚动,所述下滚轮的胎面与轨道的侧部底面接触并可沿轨道的侧部底面滚动;本发明通过在立板上设置侧滚轮和下滚轮的方式,在侧滚轮保证行车出现侧翻的前提下,通过在轨道侧部底面增设下滚轮,当行车在下坡或者底板左右不平的情况下行驶时,为了避免行车由于惯性出现飞起脱离轨道的情况发生,设置在轨道侧部底部的下滚轮可以阻止行车脱离轨道底面,对行车起到垂直轨道方向的限位作用,保证行车运行的稳定性。
