Crane with anti-roller operation trolley and position-adjustable car bumper

Abstract

This application discloses a crane with a running trolley with anti-rolling wheels and an adjustable block position, which includes two end girders and two main girders, which form a bridge structure; one of the main girders is equipped with a pick-up frame and hanging cables on the outside; There is a track on the top of the main beam, and the running trolley is connected to the track; both ends of the end beam are equipped with a cart driving device and an anti-tipping device; a steel rail parallel to the above-mentioned track is installed on the inner side of the main beam, and the rail step Face down; two sets of anti-roller devices are connected to each side of the trolley, and the anti-roller devices are lapped on the rail; the trolley is equipped with a rotating mechanism; the boom shaft in the rotating mechanism is connected to the cantilever member; the cantilever on the cantilever The beam is equipped with an electric hoist and can move back and forth horizontally along the cantilever beam; the cantilever beam is located under the main beam and can rotate; the cantilever beam is connected with a car stop device and its position is adjustable.

Description

technical field [0001] The present application relates to the field of cranes, in particular to a crane with a traveling trolley with anti-rolling wheels and an adjustable gear position. 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
