Anti-tilting crane with hung end beam trolley and balanced end beams

Abstract

This application discloses a crane with suspended end girder trolley and balanced end girder anti-tipping, including double-girder bridge frame; double-girder bridge frame includes end girder and main girder; end girder is connected by two balanced end girders and a connecting rod in the middle One end of the balanced end beam is connected to the driving device of the cart, and the other end is connected to the passive wheel group; two ends of the end beam are respectively connected to a set of anti-tipping device; there is a track under the main beam; Connect the buffer; the two rails are connected to the suspended end beam trolley; the suspended end beam trolley is equipped with a rotating mechanism; the lower end of the boom shaft in the rotating mechanism is connected to the cantilever member, and the upper end is connected to the collector slip ring; the electric motor is installed on the cantilever member. The hoist can also move back and forth along the cantilever beam; the cantilever beam is under the main beam and can rotate at any angle; the cantilever beam is connected with a car stop device and its position can be adjusted; on the electrical connection.

Description

technical field [0001] The present application relates to the field of cranes, in particular to a 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 be pulled obli...

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
