Bridge type cantilever crane provided with suspension end beam trolley and movable car stops

Abstract

This application discloses a bridge-type cantilever crane with a suspended end girder trolley and a movable car block, which includes a double-girder bridge frame; a cart running device and a safety hook are provided on the end beam of the bridge frame; a track is provided under the main beam of the bridge frame, The two ends of the track are connected to the stop device; the suspension end beam is connected to the track; the two ends of the suspension end beam are respectively connected to the driving mechanism and the buffer; the trolley frame is connected between the two suspension end beams to form a suspension end beam trolley; A pair of driving wheels on the mechanism with gears; a pair of driving wheels are connected to the transmission shaft through a transition gear; the output shaft on the driving mechanism is meshed with a driving wheel; the center of the suspended end beam trolley is equipped with a rotating mechanism; Collector slip ring, the lower end is connected to the cantilever member; the cable of the electric hoist on the cantilever member passes through the center of the boom shaft and is connected to the above collector slip ring; Rotate at any angle.

Description

technical field [0001] The present application relates to the field of cranes, in particular to an overhead cantilever crane with a suspended end beam trolley and a movable gear block. 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 pu...

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
