Cantilever crane with open drive rotating mechanism

Abstract

The invention discloses a cantilever crane with an open drive rotating mechanism. The cantilever crane comprises two end beams and two girders, wherein the ends of the two girders are connected with the two end beams and the two girders are perpendicular to the two end beams; a cable hanging frame is arranged on the outer side face of one girder; the two end beams are provided with cart travelling devices; rails above the two girders are connected with a travelling trolley; a cable on the travelling trolley is connected with a hanging cable on the cable hanging frame; side rails are arranged above the outer side faces of the two girders; the lower side of each side rail is in clearance connection with a safety hook, and one end of each safety hook is connected with the travelling trolley; the open drive rotating mechanism is arranged in the center of the travelling trolley; a suspender shaft in the open drive rotating mechanism is connected with a cantilever component; a rotating limit device is arranged between the cantilever component and the travelling trolley; an electric hoist is mounted on a cantilever beam on the cantilever component and can move horizontally back and forth along the cantilever beam; and the cantilever beam is arranged below the two girders and can rotate.

Description

technical field [0001] The present application relates to the field of cranes, in particular to a cantilever crane with an open transmission rotation mechanism. Background technique [0002] Existing bridge cranes are used in enterprise workshops. Some workshops are equipped with many machine tools for processing and production. Products and raw materials need to be transported to the next workshop or other departments in real time; the hooks of the cranes in the workshop are hung from the trolley. For hoisting goods, the trolley can only run back and forth along the double girders of the crane, and the crane can only run back and forth along the cart rails on the cross columns on both sides of the workshop, so that the range of goods that the crane hook can lift is within the distance between the two cart rails in the workshop. Within the plane surrounded by the two ends, when the goods at the edge of the plane need to be hoisted, the hook will be pulled obliquely, and the ...

Problems solved by technology

[0002] Existing bridge cranes are used in enterprise workshops. Some workshops are equipped with many machine tools for processing and production. Products and raw materials need to be transported to the next workshop or other departments in real time; the hooks of the cranes in the workshop are hung from the trolley. For hoisting goods, the trolley can only run back and forth along the double girders of the crane, and the crane can only run back and forth along the cart rails on the cross columns on both sides of the workshop, so that the range of goods that the crane hook can lift is within the distance between the two cart rails in the workshop. Within the plane surrounded by the two ends, when the goods at the edge of the plane need to be hoisted, the hook will be pulled obliquely, and the items farther away from this plane (such as outside the workshop door, outside the span) cannot be hoisted. At this time, it can only be transferred with the help of other transportation equipment. Usually, the car drives into the workshop to lift the goods under the hook. Go to the hook to hand over the goods, and some set up a special cantilever crane at the workshop door (or workshop aisle) to transfer and dispatch the goods outside the workshop, first hoist the goods into the place where the crane hook of the workshop can reach , and then the cargo is hoisted by the crane to other stations in the workshop. The existing bridge crane used in this working condition cannot directly transfer the cargo with the workshop next door, and must use other transportation equipment to schedule operations, which brings considerable inconvenience. It also wastes manpower and material resources
