Crane with two travelling trolleys and with cantilever beams capable of rotating at any angle

Abstract

This application discloses a crane with two running trolleys and a cantilever beam that can rotate at any angle, including a double-girder bridge frame composed of two end beams and two main beams; The electric frame and hanging cable are connected outside the walking platform; two running trolleys are connected to the track above the main girder; the end girder is composed of a balanced end girder and a connecting rod; The beam is connected with an anti-tipping device; both sides of the running trolley are connected with anti-roller devices, and the anti-rolling device hooks on the rails on the outer side of the main beam to run; the running trolley is driven by a ZSC reducer; the running trolley is equipped with a rotating mechanism; the rotating mechanism The lower end of the boom shaft is connected to the cantilever member, and the upper end is connected to the current collector slip ring; the electric hoist is installed on the cantilever beam in the cantilever member; the cantilever beam is located under the main beam and can be extended outside the workshop, and can be rotated at any angle on the horizontal plane .

Description

technical field [0001] The present application relates to the field of cranes, in particular to a crane with two running trolleys and a cantilever beam that can rotate at any angle. 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 pulle...

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
