Description

Technical Field

[0001] The utility model relates to the technical field of safety nets, in particular to a fall-prevention safety net device for construction engineering. Background Art

[0002] In modern society, with the acceleration of urbanization and the continuous development of construction projects, aerial work and activities at height are becoming increasingly frequent. At the same time, the risk of various accidental falls has also increased, posing a serious threat to people's lives and safety. Against this backdrop, fall prevention nets have emerged as a vital safety device.

[0003] The history of fall prevention nets dates back to the early days of construction and industry. In the past, workers faced a high risk of falling while working at heights due to a lack of effective protective measures. With the gradual rise of safety awareness, people began to explore various methods to prevent falls. Initial fall prevention measures were relatively simple, such as simple railings and safety belts.

[0004] With the advancement of technology and the increasing demand for safety, specially designed fall protection nets have gradually emerged. These early fall protection nets mainly consisted of ropes and metal mesh. By fixing them to the edge of buildings or structures, they provided a certain buffer and interception effect to reduce the damage caused by falls.

[0005] Chinese patent CN219045325U discloses a construction anti-fall safety net, comprising a mounting frame, a winding roller rotatably mounted on the inner wall of the mounting frame, one end of a pull rope fixedly connected to the curved outer wall of the winding roller, the other end of the pull rope fixedly connected to the safety net, and a blocking mechanism provided on the lower surface of the mounting frame. To prevent the safety net from repeatedly shaking when struck by falling objects, thereby reducing the effectiveness of the safety net, the construction anti-fall safety net is provided with a blocking mechanism that cooperates with an elastic member and a connecting rod so that the blocking plate has a blocking effect on the upward movement of the pull rope, reducing the speed of the pull rope being wound by the winding roller, thereby reducing the upward movement of the safety net after being impacted, thereby reducing the kinetic energy of the falling object when impacting the safety net, and improving the effectiveness of the safety net.

[0006] Although the above technical solution reduces the upward movement tendency of the safety net after being impacted, thereby reducing the kinetic energy of the falling objects on the safety net and improving the use effect of the safety net, it only provides a protective measure with the safety net. Once a person falls, it is difficult for the fallen person to maintain a comfortable posture and wait for rescue because the safety net does not have good support. It is also easy to cause shaking and secondary danger. Utility Model Content

[0027] like Figure 1-4As shown, in this embodiment, a fall prevention safety net device for construction engineering includes a support mechanism, which is connected to an anti-fall net 1 through a buffer device. A support plate 2 is also provided under the anti-fall net 1, and the support plate 2 is connected to the support mechanism for lifting.

[0028] In this embodiment, the support mechanism includes two symmetrically supported support beams 3, one end of the support beam 3 is fixedly connected to the wall, and the other end of the support beam 3 is connected to a pull rope 4, which is arranged obliquely upward and the other end of the pull rope 4 is connected to the wall.

[0029] In order to improve safety and prevent rolling from the anti-fall net 1, in this embodiment, the anti-fall net 1 includes a bottom net 1-1, a fence 1-2 is provided on the upper side of the bottom net 1-1, and a suspension rod 1-3 is horizontally provided on the top of the left and right sides of the fence 1-2.

[0030] In order to prevent the anti-fall net 1 from bouncing up and down repeatedly and causing secondary danger when a fall occurs, in this embodiment, the buffer device includes a plurality of elastic components, and the plurality of elastic components are evenly distributed on the support beam 3. The elastic component includes a cylinder, the upper end of the cylinder is connected to the support beam 3, a spring 5 is provided in the cylinder, the upper end of the spring 5 is connected to the top of the cylinder, and a slider 6 is provided at the lower end of the spring 5. The slider 6 is provided with an elastic piece 7 arranged obliquely upward around the periphery of the slider 6, and a plurality of slots 8 are vertically arranged at the position corresponding to the elastic piece 7 at the bottom of the cylinder, and the bottom of the slider 6 is connected to the suspension rod 1-3 through a suspension rope.

[0031] In this embodiment, a fixed pulley 9 is provided in the middle of the sides of the two support beams 3, and a connecting bracket 10 is provided in the middle of the upper surface of the side of the support plate 2. The top end of the connecting bracket 10 is connected to a traction device in the building via a rope passing through the fixed pulley 9. In this embodiment, the traction device is an electric winch.

[0032] In order to prevent collision with the cylinder when falling and to improve the sealing performance, in this embodiment, an anti-collision baffle 11 is provided on the inner side of the support beam 3 to shield the buffer device, and the outer layer of the anti-collision baffle 11 is wrapped with sponge.

[0034] The working principle and beneficial effects of the above technical solution are:

[0035] When in use, when a person or object falls onto the anti-fall net 1, the anti-fall net 1 moves downward. During the movement, the springs 5 in the elastic components act as a deceleration buffer to reduce the damage caused by the fall. When the anti-fall net 1 falls to the lowest point, the springs 5 contract, driving the slider 6 to start moving upward. At this time, the spring piece 7 moves and engages with the nearest slot 8 above it, thereby limiting the vibration of the anti-fall net 1. When rescuers arrive, the traction device winds the rope to make the support plate 2 rise, thereby supporting the person and providing a stable support to facilitate subsequent rescue.

[0036] Compared with the prior art, the utility model further provides a support plate 2 under the anti-fall net 1. Once a person falls, the support plate 2 can be lifted to provide the fallen person with a relatively stable support point, which is convenient for subsequent rescue. At the same time, when falling objects occur, once the falling objects cut or break through the anti-fall net, the support plate can play a supporting role to prevent the danger caused by falling objects from high altitude.

In order to limit the downward rotation of the support beam 3, a limit plate 12 is further provided at the bottom of the support beam 3, and one end of the limit plate 12 is fixedly connected to the wall.

[0038] The above are only preferred embodiments of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed in the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
