Cantilever crane provided with double trolleys and adopting sector gears for transmission

Abstract

This application discloses a cantilever crane with double trolleys and fan gear transmission, which includes two end beams and two main beams, the ends of the two main beams are respectively connected to the two end beams; There is a trolley running device; two end beams are connected with safety hooks; I-steel rails are installed under the two main beams; both ends of the I-steel rails are connected to the car stop device; the lifting trolley is connected between the two I-steel rails and the suspended end beam trolley; the suspended end beam trolley is provided with a rotating mechanism with fan gear transmission; one end of the boom shaft in the rotating mechanism is connected to the cantilever component; the cantilever component is provided with a rotation limit device; the cantilever beam on the cantilever component The electric hoist is installed, and the electric hoist can move back and forth horizontally along the cantilever beam; the cantilever beam is located under the two main beams and can rotate; two end beams are each equipped with a lifting frame, and two steel cable rails are connected between the lifting frames , the two steel cable rails are connected with hanging cables.

Description

technical field [0001] The present application relates to the field of cranes, in particular to a cantilever crane with double trolleys and sector gear transmission. 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
