Bridge cantilever crane with two travelling trolleys and horizontal wheel devices

Abstract

This application discloses a bridge-type cantilever crane with two running trolleys and a horizontal wheel device, which includes a bridge frame composed of two end girders and two main girders; Connect the electric frame and hanging cable; connect two running trolleys on the track above the main beam; set a set of horizontal wheel devices at both ends of the end beam; set rails on the outside of the main beam; The hook runs on the rail; the two driving wheels on the running trolley are connected to the same driving axle to drive; the center of the running trolley is equipped with a rotating mechanism; the lower end of the boom shaft is connected to the cantilever member, and the upper end is connected to the collector slip ring; The electric hoist can also move back and forth horizontally along the cantilever beam; the cantilever beam can be stretched out of the workshop when it is under the main beam, and can rotate at any angle on the horizontal plane.

Description

Technical field [0001] This application relates to the field of cranes, in particular to a bridge cantilever crane with two running trolleys and horizontal wheel devices. Background technique [0002] Existing bridge cranes are used in enterprise workshops. In some workshops, many machine tools and equipment 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 crane hook on the workshop is suspended 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 rails on the span columns on both sides of the workshop, so that the range of goods that the crane hook can lift is within the two cart rails of the workshop In the plane enclosed by the two end points, when the goods on the edge of this plane need to be hoisted, the hook will be inclined, and the goods far away from ...

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
