Safe and durable hoisting hook of bridge crane

Abstract

The invention discloses a safe and durable hoisting hook of a bridge crane and belongs to the technical field of hoisting equipment. The safe and durable hoisting hook comprises a pulley cover, a pulley located in the pulley cover and a hoisting steel rope assembled on the pulley in a matched mode, and is characterized in that frames are arranged at the two ends of the pulley cover, and a buffering airbag covering the outside of the pulley cover is arranged between the frames at the two ends; a plurality of distance sensors are arranged on the periphery of one of the frames and connected with a controller; an inflation pump and a storage battery are further arranged on the pulley cover, and the inflation pump communicates with the buffering airbag through an air pipe; the storage battery and the inflation pump are in electric connection with the controller; a lubricating oil sleeve movably arranged outside the hoisting steel rope in a sleeving mode is arranged on a bracket; an oil jet hole is radially formed in the wall of an inner hole in the lubricating oil sleeve; and a shock absorption frame is connected with the lower end of the pulley cover through bolts. The problem that a hook of an existing crane is prone to colliding and damaging site facilities to cause safety accidents is solved.

Description

technical field [0001] The invention relates to the technical field of lifting equipment, in particular to a safe and durable lifting hook of a bridge type crane. Background technique [0002] At present, the cleaning of the bridge crane track is generally to use the lifting hook to lift and transfer the goods to be carried. The quality of the lifting hook is relatively heavy. The lifting hook includes a pulley cover, a pulley and a hook on the pulley cover. , the crane realizes the lifting of the lifting hook through the transmission between the steel rope and the pulley. Due to the large volume and heavy weight of the lifting hook during the on-site operation, the swing of the lifting steel rope is relatively large, so It is easy to cause a collision between the lifting hook and the on-site equipment, or a collision with the on-site workers, which is prone to safety accidents and damage to the on-site facilities. [0003] On the other hand, under the long-term interaction...
