Lifting hook capable of holding goods in emergency during falling

Abstract

The invention discloses a lifting hook capable of holding goods in emergency during falling. The lifting hook comprises a lifting hook body, wherein a placing cavity with an upward opening is formed in the lifting hook body, a placing plate is connected to the placing cavity in an up-down sliding mode, a main liquid cavity is formed in the lower wall of the placing cavity in a communicating mode,a reset spring cavity located on the left side of the main liquid cavity is formed in the lower wall of the placing cavity in a communicating mode, a reset spring is fixedly connected between the lower wall of the reset spring cavity and the lower end surface of the placing plate, a main connecting block located on the right side of the reset spring is fixedly connected to the lower end surface ofthe placing plate, and a main piston plate which is in sliding connection with the main liquid cavity is fixedly connected to the lower end surface of the main connecting block. According to the lifting hook, the placement of the goods is sensed through the spring placing plate, after the goods are placed, pressing blocks on the left side and the right side are pushed through a hydraulic piston cylinder to hold a hanging rope so as to prevent the hanging rope from falling off, and then the front side and the rear side of the hanging rope are held again.

Description

technical field [0001] The invention relates to the related field of cranes, in particular to a lifting hook that can be held tightly tightly when cargo falls. Background technique [0002] In many engineering projects, cranes are needed to lift some heavy goods, and because of the heavy weight of these goods, there will be many accidents during the transportation process, especially the process of transporting goods to high places During the process, the goods may be separated from the lifting hook due to shaking and strong wind, and even the lanyard may break and cause the goods to fall and other accidents. Some existing cranes are difficult to prevent the lanyard from falling off well, and it is even more difficult to take protective measures when the lanyard breaks accidentally, and the protection is poor. The invention discloses a lifting hook that can be held tightly tightly when the goods fall, which can solve the above problems. Contents of the invention [0003]...
