Hanging hook dangling limiting mechanism of bridge crane

Abstract

The invention provides a bridge crane hook dangling limiting mechanism which comprises a fixing frame, a left electric push rod and a right electric push rod, and the left electric push rod and the right electric push rod are fixedly installed on the two sides of the top of the fixing frame respectively. A left electric push rod and a right electric push rod are installed on the two sides of the fixing frame correspondingly, dragging rods are installed on output shafts of the left electric push rod and the right electric push rod correspondingly, and when the crane carriage moves forwards, the left electric push rod located on the rear portion stretches, so that a lifting rope on the rear portion is pulled by dragging a limiting base, and the lifting rope is lifted. And similarly, when the hoisting trolley stops, the right electric push rod in the front extends, so that the hoisting hook and the heavy object have the trend of moving backwards, the impulsive force brought by inertia of the heavy object is counteracted, and dangling can be effectively prevented. And the use safety is improved.

Description

technical field [0001] The invention belongs to the technical field of crane accessories, and in particular relates to a suspension hook suspension limit mechanism of a bridge crane. Background technique [0002] A bridge-type crane whose bridge runs on elevated tracks, also known as a crane. The bridge frame of the bridge crane runs longitudinally along the rails laid on the elevated sides on both sides, and the hoisting trolley runs horizontally along the rails laid on the bridge frame, forming a rectangular working range, which can make full use of the space under the bridge frame for hoisting and transporting materials. Hindered by ground equipment, this kind of crane is widely used in indoor and outdoor warehouses, workshops, docks and open-air storage yards. When lifting objects, under the action of inertia, the heavy objects will run one step slower than the lifting trolley , when the lifting trolley stops, the weight will rush forward again, which will cause the wei...

Problems solved by technology

The bridge frame of the bridge crane runs longitudinally along the rails laid on the elevated sides on both sides, and the hoisting trolley runs horizontally along the rails laid on the bridge frame, forming a rectangular working range, which can make full use of the space under the bridge frame for hoisting and transporting materials. Hindered by ground equipment, this kind of crane is widely used in indoor and outdoor warehouses, workshops, docks and open-air storage yards. When lifting objects, under the action of inertia, the heavy objects will run one step slower than the lifting trolley , when the lifting trolley stops, the weight will rush forward again, which will cause the weight to swing and reduce the safety of lifting. However, the existing bridge cranes cannot solve the above problems. Therefore, the present invention proposes a Hook Suspension Limit Mechanism of Bridge Crane
