Description

Technical Field

[0002] Tower cranes are essential mechanical equipment in the construction process and are commonly found at construction sites of all kinds of construction sites. They are used for vertical and horizontal transportation of various materials or components. In recent years, accidents involving lifting and hoisting have occurred frequently, especially for the risks of lifting during nighttime construction. When no warning devices are set up, there are no other warnings and barriers except for increasing on-site lighting and raising workers' awareness, which poses a great safety hazard.

[0003] The existing announcement number is CN210594994U, and its name is a warning device for a tower crane. It is installed on the luffing mechanism of the tower crane. The warning device includes a fixed frame and a first light-emitting body and a second light-emitting body arranged on the fixed frame. The first light-emitting body is used to perform aerial positioning of the warning device and the luffing mechanism through the position of the light source when the first light-emitting body is emitting light, and the second light-emitting body is used for vertical spatial and ground positioning of the luffing mechanism. The warning device is arranged on the luffing mechanism of the tower crane to locate and track the motion trajectory of the tower crane, thereby solving the problem of night positioning of the luffing mechanism of the tower crane and reducing the risk of night lifting operations.

[0004] With respect to the above-mentioned related technologies, the inventors found that the above-mentioned tower crane warning device uses a single point-shaped lighting lamp as a warning method, which can only warn the position of the tower crane but cannot warn the outline of the tower crane. This results in that when the tower crane is under construction at night, it is not conducive for workers to observe the specific outline position of the tower crane in detail, affecting the safety of the tower crane construction.
