Bridge type cantilever crane with reaction wheel type running trolley and safety hooks

Abstract

This application discloses a bridge-type cantilever crane with a trolley running on reverse rollers and a safety hook. It includes two end girders and two main girders to form a double-girder bridge structure; The running trolley is connected to the track above the beam; both ends of the end beam are equipped with a cart driving device with wheel rims and gear teeth and an anti-tipping device; steel rails are set on the outside of the main beam; both sides of the running trolley are connected with anti-rolling device The device runs on the rails; the two active wheel groups on the running trolley are driven independently; the running trolley is equipped with a rotating mechanism; the thrust bearing in the rotating mechanism is connected to the upper part of the bearing seat; the lower part of the boom shaft in the rotating mechanism is connected to the cantilever The components are connected, and the upper part is connected to the collector slip ring; the electric hoist is installed on the cantilever component and can move back and forth horizontally along the cantilever beam; the cantilever beam is under the main beam 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 an overhead cantilever crane with a running trolley and a safety hook. 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, an...

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
