The invention discloses a cam type crane. The cam type crane comprises a frame, wherein rollers are mounted at the bottom end of the frame; a convex groove wheel is rotationally mounted on the frame; a driving motor is in transmission connection outside the convex groove wheel; a lifting rod is slidingly arranged on the frame; the lower end of the lifting rod fits the convex groove wheel in a sliding manner; a support plate is rotationally arranged at the upper end of the lifting rod; and a lifting hook is connected to the lower end of the support plate. The cam type crane solves the problems of low lifting height, low space utilization rate of factory buildings, complex manufacturing process and instable structure in the prior art, and adopts a cam form to achieve the effects of stable actions and high positioning accuracy.
Description
technical field [0001] The invention relates to the field of cranes, in particular to cam cranes. Background technique [0002] Existing single-girder cranes generally have a structure in which both ends of the main girder are fused on the end girder, and the hoist trolley is hung at the bottom of the main girder in a U-shape. In this way, the distance between the bottom end of the hoist trolley and the ground is relatively close, and the lifting height of objects is low. The factory building must be built higher to lift large objects, which increases the input cost of the factory building to a certain extent and reduces the cost of the factory building. Space utilization. Moreover, such a single girder crane has a complicated manufacturing process, requires a large number of welding processes, has low structural stability, and has low lifting weight. Contents of the invention [0003] The purpose of the present invention is to address the deficiencies of the prior a...
