Crane with underslung trolley and position-adjustable bumper posts and capable of rotating at any angle

Abstract

The application discloses a crane with a suspension trolley and a position-adjustable car stopper that can be rotated at any angle, including a double-girder bridge frame with an end girder and a main girder; ;The suspension trolley is connected to the track below the main beam; the suspension trolley is provided with a rotating mechanism with fan gear transmission; the lower end of the boom shaft in the rotating mechanism is connected to the cantilever member, and the upper end is connected to the collector slip ring; the cantilever member includes cantilever beam, Suspension seat; the suspension seat is welded at one end of the cantilever beam; the buffer is fixed at one end of the cantilever beam close to the suspension seat, and the other end is connected with the car stop device, and the position of the car stop device is adjustable; the cantilever beam is connected with an electric hoist and can be moved along The cantilever beam moves horizontally; the cantilever beam is under the main beam and can rotate at any angle.

Description

technical field [0001] The present application relates to the field of cranes, in particular to a crane with a suspension trolley and an adjustable position of the car stop, which can be rotated 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 hois...

AI Technical Summary

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
