Cantilever crane with underslung trolley and balance end beam bodies and collector slip ring

Abstract

The application discloses a cantilever crane with a suspension trolley, a balanced end beam and a current collector slip ring, including a double-girder bridge frame with an end beam and a main beam; the end beam is composed of a balanced end beam and a connecting rod; There is a cart driving device and a horizontal wheel device; the suspension trolley is connected to the track under the main beam; 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 rails; Multiple driving mechanisms are connected to the trolley frame; the trolley frame is equipped with a roller device next to the driving mechanism; the trolley frame is connected to the rotating mechanism; the lower end of the boom shaft in the rotating mechanism is connected to the cantilever member, and the upper end is connected to the collector Slip ring; electric hoist is installed on the cantilever member; the cantilever member is under the main beam and can rotate at any angle 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 suspension trolley, a balanced end beam and a collector slip ring. 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 b...

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
