The main characteristics of construction projects include: Comprehensiveness: Construction projects involve multiple professional fields and require the collaborative work of multiple trades. Complexity: Construction projects are large in scale, and the construction process is complex and changeable, requiring meticulous management. Durability: Buildings usually have a long service life, so their quality and safety are of paramount importance. High investment: Construction projects require a large amount of capital, manpower, and material resources.

[0003] Among them, during the construction of construction projects, protective measures will be used to protect against risks that may exist during the construction process of construction projects; for example, when construction workers enter the employee passage inside the construction building, protective measures are needed to protect the top of the employee passage to prevent employees from being injured by falling objects from high altitude when entering the construction building.

[0027] Working principle: When in use, the utility model pushes and moves the main frame 1 to the construction site of the construction project that requires fall protection. When the main frame 1 is pushed and moved to the construction site that requires fall protection, the inner side of the lower end of the main frame 1 can be used for construction workers to pass through. When the construction workers pass through, the side ends of the passers-by are protected by the side protection grilles 5. At the same time, the electric telescopic rod 6 is turned on by control. When the electric telescopic rod 6 is turned on, the side protection grilles 5 are driven to swing and adjust, so that the side protection grilles 5 can swing and adjust the protection position. The top of the passers-by is protected by the protective top plate 11. When falling objects fall to the upper end of the protective top plate 11, the protective top plate 11 will be forced to move downward. When the protective top plate 11 moves downward, it will bring When the limit slide bar 8 moves downward in a straight line, the limit ring 9 will be driven to move downward in a straight line. When the limit ring 9 moves downward in a straight line, the support spring 10 will be stretched downward. When the support spring 10 is stretched downward, the elastic potential energy generated by the stretching deformation of the support spring 10 will push the limit ring 9 and the limit slide bar 8 in the opposite direction, so that when the falling object falls to the upper end of the protective top plate 11, the protective top plate 11 will be subjected to force buffering.

[0028] At the same time, the connecting rod 19 is pulled downward by the pull ring 20. When the connecting rod 19 is pulled downward, the pin 18 is driven to move linearly downward, and the reset spring 21 is stretched downward. When the pin 18 moves linearly downward, the two main frames 1 are docked front and back. When the two main frames 1 are docked front and back, the limiting boss 14 is inserted into the inner wall of the limiting groove 16. When the limiting boss 14 is inserted into the inner wall of the limiting groove 16, the first pin hole 15 is vertically aligned with the second pin hole 17. When the first pin hole 15 is vertically aligned with the second pin hole 17 During alignment, by releasing the force of pulling the connecting rod 19, when the force of pulling the connecting rod 19 is released, the elastic potential energy generated by the stretching of the reset spring 21 will drive the connecting rod 19 to reset upward in the opposite direction. When the connecting rod 19 resets upward, it will drive the pin 18 to reset upward and be plugged into the inner wall of the second pin hole 17 and the first pin hole 15, so that the pin 18 cooperates with the second pin hole 17 and the first pin hole 15 to limit the docking of the main frame 1, thereby realizing fall protection during construction of construction projects and facilitating the docking of several main frames 1 to extend the protection area.
