Cantilever crane provided with lifting trolley and suspension trolley and capable of rotating at any angle

Abstract

The application discloses a cantilever crane with a lifting trolley and a suspension trolley that can rotate at any angle, including a double-girder bridge frame; the double-girder bridge frame includes an end beam and a main beam; the two ends of the track below the main beam are welded with stoppers and buffers; The lifting trolley and the suspension trolley are connected to the two rails; the suspension trolley is equipped with a rotation mechanism; the lower end of the boom shaft in the rotation mechanism is connected to the cantilever member, and the upper end is connected to the collector slip ring; the electric hoist is installed on the cantilever The cantilever beam moves horizontally; the cantilever beam is located under the main girder and can rotate at any angle; the end girder of the double-girder bridge is equipped with a lifting frame, and two steel cable rails are connected between the two lifting frames. The two hanging cables are respectively connected to the electrical connections on the suspension trolley and the lifting trolley.

Description

technical field [0001] The present application relates to the field of cranes, in particular to a cantilever crane with a hoisting trolley and a suspension trolley that can rotate at any angle. 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 w...

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
