Anti-tilting crane with two hanging beam trolleys and balance beams

Abstract

The invention discloses an anti-tilting crane with two hanging beam trolleys and balance beams. The anti-tilting crane comprises a double-beam bridge, wherein each beam in the bridge is formed in a way that the balance beams and a connecting rod are combined; one end of each balance beam is connected with a cart driving device, and the other end of each balance beam is connected with a passive wheel group; anti-tilting devices are respectively connected to both ends of each beam; the two hanging beam trolleys are connected between tracks below two main beams; rotary mechanisms with sector geartransmission are arranged on the hanging beam trolleys; cantilever members are connected to the lower ends of boom shafts, and safety rulers are connected to the upper ends of the boom shafts; electric blocks are installed on the cantilever members and can move back and forth along cantilevers; the cantilevers are located below the main beams and can rotate; and a trolley hung cable device is arranged on the double-beam bridge, and two hung cables which can independently move are arranged on the trolley hung cable device.

Description

technical field [0001] The present application relates to the field of cranes, in particular to a crane with two suspended end beam trolleys and a balanced end beam 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.

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
