Abstract
The invention discloses a rapid moving method for a portal crane. According to the rapid moving method, grooves are formed in the peripheral faces of two walking wheels which are arranged at interval, wherein convex parts on the two sides of the grooves are covered with outer gear rings; a motor and a driving gear which is arranged above the walking wheels and are engaged with the outer gear rings are further included; the output end of the motor is connected with the driving gear; in a movement process, the grooves have the effect of limiting the walking wheels so as to prevent the walking wheels from being laterally moved; the outer gear rings are arranged so that the stress on the left and right ends of the grooves is uniform, and the condition that the movement stability of the portal crane is influenced due to the increasing of friction between the walking wheels and a portal crane main body structure as one end of each groove is intensively stressed so as to be inclined is avoided; meanwhile, the grooves are internally coated with lubricating oil so as to reduce the friction among the walking wheels, a steel rail and the driving gear, and further the stability of the device is improved; the high abrasion and high risk influences caused by chain connection in a process of moving a traditional portal crane are also avoided.
