DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See Figures 1 to 3 In the embodiment of the present utility model, a building construction safety anti-falling net includes two groups of side fixed steel pipes 1, the bottom of the two groups of side fixed steel pipes 1 are fixedly connected with a bottom cross bar 5, the top of the two groups of side fixed steel pipes 1 are fixedly connected with a top cross bar 6, both sides of the top cross bar 6 are rotatably connected with a rotating seat 7, the rotating seat 7 is fixedly connected with a rotating frame 8, the inner wall of the rotating frame 8 is fixedly connected with a mounting hook 9, and the mounting hook 9 is installed with an anti-falling net 10.

[0020] A traction rope 14 assembly is installed on the rotating frame 8 for pulling the rotating frame 8, and a mounting and fixing assembly is installed in the side fixed steel pipe 1 for mounting and fixing the side fixed steel pipe 1;

[0021] The utility model first installs and fixes the equipment to the outer wall of the scaffolding outside the building by installing the fixing assembly, and then rotates the rotating frame 8 to the side away from the scaffolding to open. At this time, the anti-falling net 10 is opened on the outside of the scaffolding. When a falling object or a falling person falls on the anti-falling net 10, the impact force generated by the fall first acts on the anti-falling net 10, so that the impact force is initially absorbed by the elastic expansion and contraction of the anti-falling net 10, and then the impact force drives the rotating frame 8 to rotate downward, thereby converting the impact force into a rotational driving force of the rotating frame 8. At this time, the rotational driving force is connected to the first rotating connecting arm 15 and the second rotating connecting arm 15. The movable connecting arm 21 acts on the telescopic connecting rod 19, and the telescopic connecting rod 19 acts on the spring 20 in the rotating cylinder 17 through the slider 18, and then the spring 20 buffers and absorbs the rotary driving force, thereby reducing the impact force on the anti-fall net 10, thereby improving the carrying capacity of the anti-fall net 10, that is, improving the safety of the equipment. At the same time, due to the elastic setting of the anti-fall net 10 and the rotating frame 8, when a falling person falls on the anti-fall net 10, the falling person can grab the traction rope 14 assembly to drive the rotating frame 8 to rotate and contract, and use the traction rope 14 as the force point, which makes it easier for workers to quickly exert force and leave the anti-fall net 10.

[0022] In one embodiment of the present invention, see Figures 1 to 3 The top of the rotating frame 8 is fixedly connected with an elastic mounting buckle 11, and the elastic mounting buckle 11 cooperates with the top cross bar 6. The utility model elastically clamps the rotating frame 8 and the top cross bar 6 through the setting of the elastic mounting buckle 11, thereby avoiding shaking during the installation and transportation process, and when the construction is completed, the rotating frame 8 can also be fixed to the top cross bar 6 through the elastic mounting buckle 11, thereby reducing the damage to the anti-fall net 10 caused by wind and sun.

[0023] In one embodiment of this invention, see Figures 1 to 3 The traction rope 14 assembly includes a fixing frame 12 fixedly connected to the top cross bar 6, and a roller 13 is rotatably connected inside the fixing frame 12. One end of the traction rope 14 is connected to the top of the rotating frame 8, and the other end of the traction rope 14 passes through the roller 13 and is arranged on the side of the side fixed steel pipe 1 away from the rotating frame 8. The utility model pulls the rotating frame 8 through the setting of the traction rope 14 and the roller 13. When the rotating frame 8 needs to be folded, the staff can pull the traction rope 14, and the traction rope 14 drives the rotating frame 8 to rotate and retract, thereby improving the safety of the staff.

[0024] In one embodiment of this invention, see Figures 1 to 3The traction rope 14 is arranged on one end of the side fixed steel pipe 1 away from the rotating frame 8 and is fixedly connected with a counterweight 22. The counterweight 22 can be placed in the anti-fall net 10. The traction rope 14 assembly places the traction end of the traction rope 14 in the anti-fall net 10 through the setting of the counterweight 22, so that the falling person can grab the traction rope 14, and then the staff can pull the traction rope 14 to drive the body to rise quickly. When the staff pulls the traction rope 14, the psychological sense of security of the faller can be effectively improved, thereby preventing the faller from shaking and rolling on the anti-fall net 10 due to fear, causing secondary injuries. At the same time, the setting of the traction rope 14 also gives the faller a force point, which is more convenient for the worker to quickly exert force and leave the anti-fall net 10.

[0025] In one embodiment of this invention, see Figures 1 to 3 The installation and fixing component includes a first installation buckle 2 fixedly connected to the bottom of the side fixed steel pipe 1, and a telescopic steel pipe 3 is slidably connected to the top of the side fixed steel pipe 1, and a second installation buckle 4 is fixedly connected to the telescopic steel pipe 3. The installation and fixing component first connects the bottom of the side fixed steel pipe 1 to the scaffolding outside the building through the first installation buckle 2, and at the same time connects the telescopic steel pipe 3 to the scaffolding outside the building through the second installation buckle 4. At the same time, the top of the side fixed steel pipe 1 is installed and fixed through the sliding connection between the side fixed steel pipe 1 and the telescopic steel pipe 3, and the relative distance between the first installation buckle 2 and the second installation buckle 4 can be freely adjusted through the sliding connection between the side fixed steel pipe 1 and the telescopic steel pipe 3 to adapt to free installation and fixation in scaffolding of different specifications.
