Description

Technical Field

[0001] The utility model relates to a tower crane with a visual hook, and belongs to the technical field of tower crane safety. Background Art

[0002] A tower crane is a large mechanical device used to lift and move heavy materials and equipment on construction sites. It is usually supported by a tall column with a beam on top, on which a lifting mechanism is installed. The end of the lifting mechanism is equipped with a hook for hanging the object to be lifted. The tower crane is usually fixed to the ground of the construction site to provide a stable support and operating platform. In construction projects, tower cranes are widely used to lift concrete, steel, building materials and other heavy equipment.

[0003] During the hoisting process, tower cranes usually communicate with the communicator through walkie-talkies to ensure the safe and orderly progress of the hoisting work. However, with the development of technology, cameras are also used in tower cranes to observe the hook and the environment around the hook in real time to facilitate hoisting. However, tower cranes are generally used on construction sites, where there will be a certain amount of dust. Dust accumulates on the camera, which will affect the clarity of the shot, so the camera needs to be cleaned.

[0004] For example, a Chinese utility model patent with the announcement number CN218320354U discloses a visualization device for a tower crane hook. By setting a cleaning mechanism, a driving member drives a rotating member to rotate, so that the cleaning part can wipe the lens of the camera module, without the need for manual climbing and cleaning or moving the variable-length trolley 30 to the near end for wiping, and cleaning is more convenient. However, in actual use, this wiping cleaning method has the problem of incomplete cleaning. Therefore, the utility model proposes a tower crane with hook visualization. Utility Model Content

A part of the surface of the hemispherical tempered glass of the hemispherical camera is sprayed and cleaned, and the control module 26 controls the motor 22 to reverse one circle, which can drive the nozzle 10 to rotate to clean the remaining part of the hemispherical tempered glass of the hemispherical camera 12. Then the control module 26 controls the motor 22 to rotate half a circle forward again, so that the nozzle 10 returns to its original position; in this process, the remaining part of the water pipe 11 at the bottom of the protective cover 3 moves with the rotation of the motor 22 under the rotational pulling force of the rotating disk 7 and the self-gravity pull of the counterweight block 14, so that the water pipe 11 will not affect the entire cleaning process.

The above examples are only used to help understand the method and core ideas of the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
