Anti-tipping double-beam crane with suspension end beam trolley and balance end beams

Abstract

This application discloses a double-girder crane with a suspended end beam trolley and a balanced end beam anti-tilt, including a double-girder bridge; the end beam in the bridge frame is composed of a balanced end beam and a connecting rod; one end of the balanced end beam is connected to a large The other end is connected to the passive wheel group; the two ends of the end beam are connected to the anti-tipping device; the track below the main beam is connected to the suspended end beam trolley; the suspended end beam trolley is equipped with a rotating mechanism with fan gear transmission; the boom The lower end of the shaft is connected to the cantilever member, and the upper end is connected to the safety ruler; the electric hoist is installed on the cantilever member and can move back and forth along the cantilever beam; the cantilever beam is located under the main girder and can rotate; the trolley hanging cable device is installed on the double girder bridge, and the trolley hanging cable device The hanging cable on the top is connected to the electrical connection on the suspended end beam trolley.

Description

technical field [0001] The present application relates to the field of cranes, in particular to a double-girder crane with a suspended end beam trolley and a balanced end beam anti-tipping. 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 ...

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
