Cantilever crane provided with hanging trolley and adopting fan gear transmission

Abstract

The invention discloses a cantilever crane provided with a hanging trolley and adopting fan gear transmission. The cantilever crane comprises a double-beam bridge frame, and the two ends of each end beam of the bridge frame are provided with large vehicle driving devices and horizontal wheel devices; the lower portion of each main beam of the bridge frame is provided with a track; the hanging trolley is connected with the tracks; the hanging trolley is provided with a rotating mechanism adopting fan gear transmission; the lower end of a derrick shaft in the rotating mechanism is connected witha cantilever component, and the upper end of the derrick shaft is connected with a safety ruler; two stroke switches are connected to a trolley frame; an electric hoist is mounted on the cantilever component and can move back and forth along a cantilever beam; the cantilever beam is located below the main beams and can stretch out of a workshop for operation; and a plurality of wire suspending frames and a cable guiding rail are arranged on the top of the bridge frame, and the cable guiding rail is connected with a hanging cable.

Description

technical field [0001] The present application relates to the field of cranes, in particular to a cantilever crane with a suspension trolley and a sector gear transmission. 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 oblique...

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
