Cantilever crane provided with suspended car and rotating mechanism

Abstract

This application discloses a cantilever crane with a suspension trolley and a rotating mechanism, which includes a double-girder bridge frame; the double-girder bridge frame includes an end beam and a main beam; the end beam is composed of a balanced end beam and a connecting rod; Car driving device and anti-tipping device; there is a track under the main beam; the suspension trolley is connected to the track; the suspension trolley is provided with a rotating mechanism; Inside the bearing seat, the boom shaft is connected to bearing A and bearing B, and bearing A and bearing B are respectively connected to both ends of the above bearing seat through a fixed cover and a flange cover; the driving device is connected to the upper end of the boom shaft through a coupling Connection; the lower end of the boom shaft is connected to the cantilever member; the electric hoist is installed on the cantilever member; the trolley hanging cable device is installed on the double girder bridge frame, and the hanging cable on the trolley cable hanging device is electrically connected to the hanging trolley.

Description

technical field [0001] The present application relates to the field of cranes, in particular to a jib crane with a suspension trolley and a rotating 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 pulled obliquely, and the i...

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
