Cantilever crane with reverse roller travelling trolley

Abstract

This application discloses a cantilever crane with a trolley running on reverse rollers, which includes a bridge structure composed of two end girders and two main girders; There is a track, and the running trolley is connected to the track; a steel rail parallel to the above track and with the tread facing down is set above the outer side of the main beam; two sets of anti-rolling wheel devices are connected to each side of the running trolley through adjusting gaskets, and the anti-rolling wheel devices are connected to each other. Connected to the rail; there is a rotating mechanism in the center of the running trolley; the boom shaft in the rotating mechanism is connected to the cantilever component; a rotation limit device is set between the cantilever component and the running trolley; a set is installed at each end of the two end beams A cart driving device and a safety hook with shaft-connected wheels; an electric hoist is connected to the cantilever member, and the electric hoist can move back and forth horizontally along the cantilever beam; the cantilever beam is placed under the two main beams and can rotate.

Description

technical field [0001] The present application relates to the field of cranes, in particular to a cantilever crane with a trolley running on anti-rolling wheels. 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 the...

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
