Bridge type cantilever crane with lifting trolley and suspension end beam trolley

Abstract

The application discloses a bridge-type cantilever crane with a hoisting trolley and a suspending end beam trolley, comprising two end beams and two main beams, safety hooks are arranged on the end beams; A hoisting trolley is connected between them; the suspension end beams are also connected to the track; the two ends of the suspension end beams are connected to driving mechanisms; the trolley frame is connected between the two suspension end beams to form a suspension end beam trolley; Anti-roller device; a pair of driving gears on the driving mechanism are equipped with gears; the output shaft of the reduction motor on the driving mechanism is meshed with a driving gear shaft with a gear shaft; a pair of driving gears are connected by a transition gear and a transmission shaft; suspension end beam There is a rotating mechanism on the trolley; one end of the boom shaft in the rotating mechanism is connected with the cantilever member; the cantilever member is provided with a rotation limit device; the cantilever member is installed with an electric hoist and can move back and forth horizontally along the cantilever beam; Below the main beam 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 hoisting trolley and 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 pull...

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
