Self-propelled conveyer

The utility model relates to a transmission device used for an intermittent automatic production line, which is composed of a travelling mechanism, a lifting mechanism, a guiding mechanism, a PC control system, etc., wherein, the travelling mechanism comprises a front trolley and a rear trolley. The travelling mechanism is installed on an H-shaped steel track. The front trolley plays the guiding role. The rear trolley is combined with a driving mechanism into integration, and the lower end of the front trolley and the lower end of the rear trolley are connected with a cross beam through a universal shaft. Both ends of the cross beam are connected with a loop chain bottle guard, the lower end of which is connected with a hanging tool through a chain wheel, and an electrical control box is fixedly connected below the cross beam. A guide mechanism is installed in the front position, the rear position, and the middle position between the cross beam and the hanging tool. The utility model has the advantages of low manufacturing cost, little space occupation, and the realization of complicated action.
