Crane provided with double trolleys and anti-tipping balancing end beams

Abstract

This application discloses a crane with double trolleys and balanced end girder anti-tipping, including a double-girder bridge frame; the double-girder bridge frame includes an end girder and a main girder; ; One end of the balance end beam is connected to the driving device of the cart, and the other end is connected to the passive wheel group; two ends of the end beam are respectively connected to a set of anti-tipping device; there is a track under the main beam; The lifting trolley and the suspended end beam trolley are connected to the two rails; the lifting trolley is provided with a lifting device; the suspended end beam trolley is provided with a rotating mechanism; the lower end of the boom shaft in the rotating mechanism is connected to the cantilever member , the upper end is connected to the collector slip ring; the electric hoist is installed on the cantilever member and can move back and forth along the cantilever beam; the cantilever beam is under the main beam and can rotate at any angle; the cantilever beam is connected with a car stop device and its position is adjustable; Two independently movable hanging cables are arranged in the hanging cable device.

Description

technical field [0001] The present application relates to the field of cranes, in particular to a crane with double trolleys and balanced end beams against tipping. 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 pulled obliquely, and ...
