Crane provided with two hanging end beam trolleys and cantilever beams capable of rotating at any angle

Abstract

This application discloses a crane with two suspended end girder trolleys and a cantilever beam that can rotate at any angle, including a double girder bridge frame with end girders and main girders; Turning device; two suspended end beam trolleys are connected to the rails below the two main beams; a rotating mechanism with fan gear transmission is installed on the suspended end beam trolley; 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 cantilever member includes a cantilever beam and a suspension seat; the suspension seat is welded at one end of the cantilever beam; the cantilever beam is made of I-beam; the cantilever beam is provided with a guide rail; The hanging cable; one end of the hanging cable passes through the center hole of the boom shaft and is connected to the collector slip ring; the electric hoist is connected to the cantilever beam, and the cantilever beam is located under the main beam and can be extended outside the workshop, and can Rotate at any angle on the horizontal plane.

Description

technical field [0001] The present application relates to the field of cranes, in particular to a crane with two suspended end beam trolleys and a cantilever beam that can rotate at any angle. Background technique [0002] Existing bridge cranes are used in enterprise workshops. In some workshops, many machine tools are arranged 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 beams of the crane, and the crane can only run back and forth along the cart tracks on the span columns on both sides of the workshop, so that the range of goods that can be hoisted by the crane hook is within the two cart tracks of the workshop. Within the plane enclosed by the two ends, when the goods on the edge of this plane need to be hoisted, the hook will be pulled di...

AI Technical Summary

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
