Crane with running trolley, balancing end beams and arbitrary angle rotation

Abstract

The invention discloses a crane with a running trolley, balancing end beams and arbitrary angle rotation. The crane comprises a double-beam bridge frame formed by two end beams and two main beams; an electric cable suspension scaffolding and a hanging cable are arranged outside one main beam; tracks are arranged on the two main beams respectively and are connected with the running trolley; each end beam is formed by connecting the two balancing end beams with a connection rod therebetween; one end of each balancing end beam is connected with a cart drive device, and the other end is connected with a driven wheel group; each end of each end beam is connected with a set of horizontal wheel device; side tracks are arranged on the outer side surfaces of the two main beams respectively; an interval below each side track is connected with a safety hook; each safety hook is connected to the running trolley; the running trolley is provided with a rotation mechanism; a thrust bearing in the rotation mechanism is connected with the upper part of a bearing seat; the lower end of a suspender shaft in the rotation mechanism is connected with a cantilever member, and the upper end is connected with a current collecting slip ring; an electric hoist is installed on the cantilever member and can move back and forth along a cantilever beam; and the cantilever beam is arranged below the main beams and can rotate with an arbitrary angle.

Description

technical field [0001] The present application relates to the field of cranes, in particular to a crane with a trolley and a balanced end 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 pulled oblique...

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
