Cantilever crane with suspended car and balance end beams

Abstract

The invention discloses a cantilever crane with a suspended car and balance end beams. The cantilever crane comprises a double girder bridge which comprises end beams and a main beam; the end beams are formed by connecting the two balance end beams and a connecting rod between the two balance end beams; one ends of the balance end beams are connected with cart driving devices, and the other ends of the balance end beams are connected with driven wheel sets; the two ends of the end beams are each connected with a horizontal wheel device, and rails are arranged below the main beam; a car bumperis arranged on the rails, and the suspended car is connected to the rails and provided with a rotary mechanism; a suspender shaft in the rotary mechanism is connected with a cantilever component whichis provided with a rotary limiting device, and an electric hoist is mounted on the cantilever component and can horizontally move along a cantilever beam which is located below the main beam and canrotate; and two wire suspending frames are arranged on the double girder bridge, and a steel cable rail is connected between the wire suspending frames and connected with a suspended 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 balanced end beam. 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...

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
