Overhead type cantilever crane provided with hanging trolley

Abstract

This application discloses a cantilever crane with a suspension trolley on a bridge frame, which includes a double-girder bridge frame with an end girder and a main girder; the end girder is composed of a balanced end girder and a connecting rod; There is an I-shaped steel track under the main beam; the suspension trolley is connected to the two tracks; the suspension trolley includes a trolley frame, a driving mechanism, and a roller device; the driving mechanism is composed of a geared motor and wheels; the wheels are connected to the edge of the track above; the drive mechanism is connected to the trolley frame; the edge of the trolley frame is connected to the roller device beside the drive mechanism, the roller device is located under the track and its centerline is parallel to the centerline of the wheel; the trolley frame is provided with a rotation mechanism; the rotation mechanism and The cantilever components are connected; the electric hoist is installed on the cantilever components; the cantilever beam can be stretched out of the workshop and can rotate on the horizontal plane.

Description

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