Bridge type cantilever crane with end beam hanging trolley

Abstract

This application discloses a bridge-type cantilever crane with a suspended end beam trolley, 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 set of cart driving device and a safety hook at each end; there is a pick-up frame between the tops of the two main girders, and the guide rails, pulleys and hanging cables are connected under the pick-up racks; rails are set under the two main girders ; The two rails are connected with the suspended end beam trolley; the cables on the suspended end beam trolley are connected with the hanging cables on the above-mentioned guide cable rail through the conductive frame; the trolley frame of the suspended end beam trolley is provided with a rotating mechanism; The boom shaft in the mechanism is connected with the cantilever member; there is a rotation limit device between the cantilever member and the trolley frame; the electric hoist is installed on the cantilever member and can move back and forth horizontally along the cantilever beam; the cantilever beam is under the two main beams And can rotate.

Description

technical field [0001] The present application relates to the field of cranes, in particular to an overhead cantilever crane with a suspended end beam trolley. 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
