Cantilever crane provided with lifting trolley, running trolley and anti-rollover end beams

Abstract

This application discloses a cantilever crane with a lifting trolley, a running trolley and an end girder anti-tipping, which includes a double-girder bridge frame composed of two end girders and two main girders; A lifting trolley and a running trolley are connected to the rails above the two main girders; both ends of the end girders are equipped with cart driving devices and horizontal wheel devices; side rails are set on the outer sides of the two main girders; The lower gap of the track is connected with a safety hook, and one end of the safety hook is connected to the running trolley; the running trolley is provided with a rotating mechanism; one end of the boom shaft in the rotating mechanism is provided with a spline head; the lower end of the boom shaft is connected to the cantilever member, and the upper end is connected to the The safety ruler is connected; the limit switch is connected on the trolley frame; the electric hoist is installed on the cantilever member and can move back and forth along the cantilever beam; the cantilever beam is under the main beam and can rotate; the position-adjustable car stop device is connected to the cantilever beam.

Description

technical field [0001] The present application relates to the field of cranes, in particular to a cantilever crane with a lifting trolley, a running trolley and an end girder with anti-tipping. 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 w...

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
