Crane provided with suspended car and balancing end beams and capable of rotating at any angle

Abstract

The invention discloses a crane provided with a suspended car and balancing end beams and capable of rotating at any angle. The crane comprises a double-beam bridge frame which comprises end beams anda main beam. Each end beam is composed by connecting the two corresponding balancing end beams and a connecting rod between the two corresponding balancing end beams. One ends of the balancing end beams are connected with cart driving devices, and the other ends of the balancing end beams are connected with passive wheel sets. The two ends of each end beam are each connected with a horizontal wheel device. The suspended car is connected to tracks below the main beam and provided with a rotating mechanism adopting fan gears for transmission. The lower end of a suspender shaft in the rotating mechanism is connected with a cantilever component, and the upper end of the suspender shaft is connected with a current collection sliding ring. An electric hoist is mounted on the cantilever component and can move back and forth along a cantilever beam, and the cantilever beam is located below the main beam and can rotate at any angle. The two end beams on the double-beam bridge frame are each connected with a wire suspending frame, a steel cable track is connected between the two wire suspending frames, and hung cables are connected to the steel cable track.

Description

technical field [0001] The present application relates to the field of cranes, in particular to a crane with a suspension trolley and a balanced end beam that can rotate at any angle. 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 pul...

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
