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

Abstract

This application discloses a cantilever crane with a hoisting trolley, a suspension trolley and a movable stopper, including a double-girder bridge frame; the double-girder bridge frame includes an end beam and a main beam; both ends of the end beam are equipped with a cart driving device and a horizontal wheel device There is a track under the main beam; the two ends of the track are connected to the car stop device; the two tracks are connected to the lifting trolley and the suspension trolley; the suspension trolley is equipped with a rotating mechanism with fan gear transmission; The cantilever component is connected to the collector slip ring at the upper end; the electric hoist is installed on the cantilever component and can move back and forth along the cantilever beam; the cantilever beam is located under the main beam and can rotate at any angle; Two rows of guide rails are connected under the frame; hanging cables are connected on the guide rails, and the hanging cables are respectively connected to the electrical connections on the lifting trolley and the suspension trolley.

Description

technical field [0001] The present application relates to the field of cranes, in particular to a cantilever crane with a hoisting trolley, a suspension trolley and movable gear blocks. 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 p...
