Cantilever crane with two travelling trolleys and anti-tipping end beams

Abstract

This application discloses a cantilever crane with two running trolleys and end girder anti-tipping, including two end girders and two main girders; Two running trolleys are connected on the track; both ends of the end beam are equipped with a cart driving device and a horizontal wheel device; the inner side of the main beam is equipped with a steel rail and the tread faces downward; two sets of anti-rolling wheel devices are connected to each side of the running trolley. The anti-roller device is lapped on the rail; the active wheel groups on the running trolley are connected by spline sleeve couplings; the running trolley is equipped with a rotating mechanism; the driving device in the rotating mechanism passes through the coupling and the boom Shaft connection; the lower end of the boom shaft is connected to the cantilever member; the cantilever member is provided with a rotation limit device; the cantilever beam is equipped with an electric hoist and can move back and forth horizontally along the cantilever beam; the cantilever beam is placed under the main beam and can rotate; the cantilever beam The car block device is connected on the top and the position is adjustable.

Description

technical field [0001] The application relates to the field of cranes, in particular to a cantilever crane with two running trolleys 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 will be pulled obliquely,...

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
