The working characteristic of tower crane is intermittent movement, that is, the corresponding mechanisms of material picking, transportation, unloading and other actions work alternately in one working cycle. The development and use of tower crane in the market are becoming more and more extensive. The hook for tower crane hoisting is an important structural part on the tower crane. The locking structure of the hook for tower crane hoisting has an important application on the hook, which plays the role of preventing objects from falling off during hoisting and preventing objects from detaching from the surface of the hook under the action of external force. Usually, the locking structure of the hook for tower crane hoisting is braked by a single-structured tongue to play a locking role, but it is not conducive to the use of elastic connection locking anti-decoupling when in use, which is convenient for taking and placing hanging objects, and greatly affects the increase of the strength of the structural connection and the safety of the object during hoisting.

[0003] The Chinese utility model patent with application number: 202321199385.X discloses a hook locking structure for tower crane hoisting, including a boom and a connecting shaft, a connecting shaft is installed at the top of the boom, a hook is installed at the bottom end of the boom, a latch is installed at the top of the hook, a pressure arm is installed on the outer wall of the boom below the connecting shaft, a hinge shaft is installed at one end of the pressure arm close to the boom, and the pressure arm is movably connected to the boom through the hinge shaft, a clamping plate is installed at the bottom end of the pressure arm, a limit block is installed on the outer wall of the boom on one side of the pressure arm, an arc groove is provided inside the limit block, a sliding shaft is provided at one end of the pressure arm close to the arc groove, and the sliding shaft is slidably connected to the arc groove. However, this type of tower crane hoisting hook locking structure can only be installed and operated by cooperating with a rope and a fixed pulley. Its installation method and working method are relatively simple and have certain usage restrictions. The hook structure cannot be directly installed on the lifting equipment to meet the installation requirements of different lifting equipment, and the installation height of the hook cannot be adjusted according to actual conditions, and its flexibility of use is poor.
