Abstract
The invention discloses a gantry crane moving mechanism which comprises two traveling wheels arranged at an interval, a motor, and a drive gear arranged above the traveling wheels and engaged with outer gear rings, wherein grooves are formed in the outer circumferential surfaces of the traveling wheels; an outer gear ring is arranged on the embossment parts on the two sides of each groove in a wrapping manner; the output shaft of the motor is connected with the drive gear. During moving, the traveling wheels are limited by the grooves and prevented from lateral displacement; the left and right ends of each groove can be uniformly stressed through the outer gear ring, so that the influence on the moving stability of a gantry crane due to enhancement of friction between each traveling wheel and a gantry crane main body structure caused by tilt due to centralized stress of one end of the groove is avoided; the inside of the groove is coated with lubricating oil, so that friction between the traveling wheel and a steel rail and between the traveling wheel and the drive gear is reduced, the stability of the device is improved, and the influence of high wear and high risk caused by chain connection when a traditional gantry crane is moved is avoided.
