Crane with reaction wheel travelling trolley and equalizing end beams

Abstract

The application discloses a crane with a running trolley and a balanced end girder, which includes a double-girder bridge frame with two end girders and two main girders; The running trolley is connected on the track; the end beam is composed of a balanced end beam and a connecting rod; one end of the balanced end beam is connected to the driving device of the cart, and the other end is connected to the passive wheel group; both ends of the end beam are connected to the horizontal wheel device; the outer side of the main beam is equipped with rails; Both sides of the trolley are connected with anti-roller devices, and the anti-roller devices are hooked and run on the rails; the two driving wheels on the trolley are connected to the same driving axle to drive; the trolley is equipped with a rotating mechanism; the lower end of the boom shaft and the cantilever member Connection, the upper end is connected to the collector slip ring; the electric hoist is installed on the cantilever member; the car stop device is connected to the cantilever beam; the cantilever beam is located under the main beam and can rotate at any angle on the horizontal plane.

Description

technical field [0001] The present application relates to the field of cranes, and in particular, to a crane with a running trolley with reverse rollers and a balancing end beam. Background technique [0002] Existing bridge cranes are used in enterprise workshops. In some workshops, many machine tools are arranged 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 beams of the crane, and the crane can only run back and forth along the cart tracks on the span columns on both sides of the workshop, so that the range of goods that can be hoisted by the crane hook is within the two cart tracks of the workshop. Within the plane enclosed by the two ends, when the goods on the edge of this plane need to be hoisted, the hook will be pulled diagonally, and ...

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
