Cantilever crane provided with hanging end beams and open-type transmission rotating mechanism

Abstract

This application discloses a cantilever crane with a suspended end beam and an open transmission rotation mechanism, which includes two end beams and two main beams, which constitute a double-girder bridge structure; two end beams are provided with cart running devices; The two main girders are equipped with a pick-up frame and a cable guide rail, and the cable guide rails are connected to the hanging cables; there are tracks under the two main girders, and the two rails are connected to the suspension end beams, and the two ends of the suspension end beams are provided with drive mechanism; a platform is connected between the two suspension end beams to form a trolley; the trolley is equipped with an open transmission and rotation mechanism; the boom shaft in the open transmission and rotation mechanism is connected to the cantilever component; an electric hoist is installed on the cantilever component, and the electric The gourd can move back and forth horizontally along the cantilever beam; the cantilever beam is under the two main beams, can be stretched out of the workshop, and can rotate.

Description

technical field [0001] The present application relates to the field of cranes, in particular to a cantilever crane with a suspended end beam and an open transmission rotation mechanism. 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...

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
