[0002] The monitoring equipment is the "eye" of the whole monitoring system, which is arranged at a position of the monitored place, so that the field of view can cover all the monitored parts. On the construction site, especially in the operation process of the tower crane, the monitoring equipment plays a crucial role. By setting monitoring cameras and sensors and other equipment around the tower crane, the working state of the tower crane and the surrounding environment can be monitored in real time, ensuring the safety and efficiency of the tower crane operation. The monitoring equipment can help the foreman or operator to discover abnormal conditions in time, take measures in advance, effectively prevent accidents, and protect the safety of the workers on the construction site. The monitoring equipment is set on the hook of the tower crane, which facilitates the movement of the hook to the vicinity of the object to be lifted, so that the worker can easily hang the hook on the object.

For example, the Chinese patent publication No. CN220116080U discloses a "video monitoring equipment of a tower crane", which protects the shooting end of the monitoring head by using a transparent sleeve and protects the monitoring head by using a protective bin, avoiding the influence of sand and dust for a long time and improving the service life. When the transparent sleeve is damaged by dirt, it can be directly and conveniently rotated and removed for replacement.

[0004] However, in actual use, the hook is often knocked during frequent use, causing damage to the monitoring equipment, which needs to be replaced. But the replacement operation is troublesome, and the bolt and other structures need to be disassembled. If the bolt is rusted and stuck together with the hook, it is difficult to separate, making the replacement of the monitoring equipment more troublesome and affecting the normal use of the tower crane.
