Cantilever crane with hung end beam trolley and capable of rotating at any angle

Abstract

The application discloses a cantilever crane with a suspended end beam trolley and can be rotated at any angle, comprising two end beams and two main beams; both end beams are provided with cart running devices; There is a pick-up frame and a cable guide rail, and the cable guide rail is connected with a pulley and a hanging cable; rails are arranged under the two main beams, and the two rails are connected to the suspension end beam trolley; the suspension end beam trolley is connected to the conductive frame and drag the pulley to move; the suspension end beam trolley is provided with a rotating mechanism; the boom shaft in the rotating mechanism is a hollow shaft; the lower end of the boom shaft is connected with the cantilever member, and the upper end is connected with a collector slip ring; the cantilever on the cantilever member The beam is connected to the vehicle stop device and its position is adjustable; an electric hoist is installed on the cantilever beam; the cantilever beam is located under the two main beams and can extend out of the workshop for operation, and can rotate at any angle on the horizontal plane.

Description

technical field [0001] The present application relates to the field of cranes, in particular to a cantilever crane with a suspended end beam trolley capable of rotating 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 pull...

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
