Cantilever crane with travelling trolley and current collection slip ring

Abstract

This application discloses a cantilever crane with a running trolley and a collector slip ring, including an end beam and a main beam; an electric pick-up frame and hanging cables are arranged on the outside of one of the main beams; a track is arranged above the main beam, and a The running trolley; the end beam is equipped with an anti-tipping device; the outer side of the main beam is equipped with a side track and a safety hook, and the safety hook is connected to the running trolley with a rotating mechanism; the boom shaft in the rotating mechanism passes through the center of the bearing seat and the thrust Bearing connection; the thrust bearing is connected to the upper part of the bearing seat; the locknut A above the thrust bearing is threadedly connected with the boom shaft, and is loosened and fixed by the bolt passing through the diameter; the driving device is connected with the small fan gear, the small fan gear and the large fan The gear meshing connection, the large fan gear is connected to the boom shaft; the cantilever member and the collector slip ring are connected to the boom shaft; the electric hoist is connected to the cantilever beam; the cantilever beam is under the main beam and can rotate at any angle; the cantilever beam is connected There are two sets of car gears and their positions are adjustable.

Description

technical field [0001] The present application relates to the field of cranes, in particular to a cantilever crane with a running trolley and a collector slip ring. 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 ...

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
