Crane with double trolleys and position-adjustable cantilever beam trolley stop

Abstract

The application discloses a crane with double trolleys and cantilever beams with adjustable position, including a double-girder bridge frame with end girders and main girders; both ends of the end girders are provided with cart driving devices and safety hooks; The two ends of the track below are connected to the stop device; the lifting trolley and the suspension end beam trolley are connected between the two tracks; the lifting trolley is provided with a hook type lifting device; the suspension end beam trolley is provided with a rotation mechanism; 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 safety ruler; two travel switches are connected to the trolley frame; the cantilever member includes a cantilever beam, a suspension seat, and a diagonal tie rod; One end, the other end of the cantilever beam is connected with the suspension seat to form a triangle structure; the end of the cantilever beam close to the suspension seat is fixedly connected to the buffer, and the cantilever end is connected to the car stop device and its position can be adjusted; the cantilever beam is connected to the electric hoist ; The cantilever beam is located under the main beam and can be stretched out of the workshop and rotated.

Description

Technical field [0001] The application relates to the field of cranes, in particular to a crane with a double trolley and a cantilever beam with adjustable positions. Background technique [0002] Existing bridge cranes are used in enterprise workshops. In some workshops, many machine tools and equipment 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 crane hook on the workshop is suspended 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 rails on the span columns on both sides of the workshop, so that the range of goods that the crane hook can lift is within the two cart rails of the workshop In the plane enclosed by the two end points, when the goods on the edge of this plane need to be hoisted, the hook will be inclined, and the goods far away from this...

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
