Crane provided with suspension end beam trolley and rotating mechanism adopting opening transmission

Abstract

This application discloses a crane with a suspended end beam trolley and a rotating mechanism with open transmission, including an end beam and a main beam; the end beam is composed of a balanced end beam and a connecting rod; Tilting device; there are tracks under the two main beams; the suspended end beam trolley connected to the tracks has a rotating mechanism; the boom shaft is connected to the thrust bearing and bearing A and bearing B; the thrust bearing is connected inside the bearing seat , Bearing A and Bearing B are respectively connected to both ends of the above-mentioned bearing housing through a fixed cover and a flange cover; the driving device is connected to the support of the reducer; the output shaft of the driving device is connected to the pinion, and the pinion is meshed with the large gear. The large gear is connected to the upper part of the boom shaft; the lower part of the boom shaft is connected to the cantilever member; the upper end of the boom shaft is connected to the safety ruler; two travel switches are connected to the small frame; the cantilever beam in the cantilever member is connected to the electric hoist; the cantilever beam It is under the main beam and can be rotated.

Description

technical field [0001] The present application relates to the field of cranes, in particular to a crane with a suspended end beam trolley and a rotating mechanism with open transmission. 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 ...

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
