The invention discloses a rail-clamping travelling wheel. The rail-clamping travelling wheel comprises an adjusting block, a frame mounting part, a bottom travelling wheel and a locking lever. The adjusting block is arranged in the middle of the locking lever and connected with the same in a threaded manner, the frame mounting part is arranged on the lower portion of the locking lever, and the bottom travelling wheel is rotationally arranged at the bottom of the frame mounting part. Two sides of the adjusting block are hinged with lateral connection arms, and a lateral connecting rod is hinged to the outer end of each lateral connection arm; lateral auxiliary wheels are arranged at the lower ends of the lateral connecting rods. During working, the bottom travelling wheel contacts with the upper surface of a rail, and the lateral auxiliary wheels are arranged on the left and right sides of the rail respectively. The rail-clamping travelling wheel is provided with the bottom travelling wheel contacting with the upper surface of the rail and the lateral auxiliary wheels contacting with the middles of the left and right sides of the rail, and is in point contact with the rail when used, so that the rail can be locked and the rail-clamping travelling wheel is more stable in travelling.
