Abstract
Description
Technical Field
[0001] This utility model belongs to the field of protective netting technology, specifically relating to a fall-prevention barrier net. Background Technology
[0002] Fall protection nets are safety devices used to prevent people or objects from falling from heights. They are widely used in construction sites, stadiums, warehouses, and other fields. Their main function is to prevent people or objects from falling from heights, thereby reducing accidents and protecting the safety of people and facilities. For example, on construction sites, fall protection nets can prevent workers from falling from heights and also prevent objects from falling from heights and causing injury to people or facilities below. They serve as the last line of defense for workers on construction sites.
[0003] Commonly used fall protection nets have only a single-layer structure. Although they have the function of interception and protection, they lack sufficient cushioning when a person falls onto the net, which can easily cause strangulation and abrasions to workers who fall on them. Utility Model Content
[0004] The purpose of this invention is to provide a fall arrest net that can provide sufficient cushioning and reduce the reaction force of the net on workers, thereby solving the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a fall arrest net, comprising a fall arrest net and a buffer net, wherein the buffer net is disposed above the fall arrest net, and the top of the buffer net is provided with equidistantly distributed pull ropes, and the top of the buffer net is provided with equidistantly distributed connecting ropes, wherein the sidewalls of the pull ropes are provided with buffer components, and a plurality of the connecting ropes are respectively fixedly connected to a plurality of the buffer components, wherein the connecting ropes are slidably connected to the corresponding pull ropes through the buffer components.
[0006] Furthermore, a first rope loop is fixedly connected to the top of the fall protection net, and one end of the pull rope is fixedly connected to the first rope loop.
[0007] Furthermore, a second rope loop is fixedly connected to the top of the buffer net, and one end of the connecting rope is fixedly connected to the second rope loop.
[0008] Furthermore, the buffer assembly includes an outer cylinder and an inner cylinder, the inner cylinder being slidably connected inside the outer cylinder, the pull rope passing through the outer cylinder and the inner cylinder, the pull rope being fixedly connected to the outer cylinder, and the pull rope being slidably connected to the inner cylinder.
[0009] Furthermore, a spring is provided inside the inner cylinder, and the two ends of the spring are fixedly connected to one end of the inner cylinder and the top end of the inner wall of the outer cylinder, respectively.
[0010] Furthermore, the outer cylinder has a groove on its side wall, and a connecting plate is fixedly connected to the top of the inner cylinder side wall. The connecting plate is slidably connected inside the groove. One end of the connecting rope is fixedly connected to the connecting plate. Reinforcing plates are symmetrically arranged at the bottom of the connecting plate, and one side of the reinforcing plate is fixedly connected to the side wall of the inner cylinder.
[0011] Furthermore, the top and bottom ends of the outer cylinder are both fixedly connected to connecting cylinders, and the connecting cylinders are fixedly connected to the pull rope.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: when a worker falls, the worker first falls onto the buffer net. As the body falls, the buffer component plays a buffering role, thereby providing sufficient cushioning and reducing the reaction force of the buffer net on the worker. As the buffer net descends, when the body falls into the anti-fall net, the anti-fall net supports the body and prevents the body from falling further. Attached Figure Description

[0019] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0020] like Figure 1As shown, a fall arrest net includes a fall arrest net 1 and a buffer net 2. The buffer net 2 is positioned above the fall arrest net 1. The top of the buffer net 2 is provided with equally spaced pull ropes 3 and equally spaced connecting ropes 4. The side walls of the pull ropes 3 are provided with buffer components 5. Several connecting ropes 4 are fixedly connected to several buffer components 5 respectively. The connecting ropes 4 are slidably connected to the corresponding pull ropes 3 through the buffer components 5.
[0021] According to the above structure, when a worker falls, the worker first falls onto the buffer net 2. As the person falls, the buffer component 5 acts as a buffer, reducing the reaction force of the buffer net 2 on the worker. As the buffer net 2 descends, when the person falls into the fall protection net 1, the fall protection net 1 supports the person and prevents the person from falling further.
[0022] like Figure 1 As shown, the top of the fall arrest net 1 is fixedly connected to a first rope loop 11, one end of the pull rope 3 is fixedly connected to the first rope loop 11, the top of the buffer net 2 is fixedly connected to a second rope loop 21, and one end of the connecting rope 4 is fixedly connected to the second rope loop 21.
[0023] According to the above structure, the pull rope 3 is connected to the fall arrest net 1 through the first rope loop 11 to improve the stability of the connection, and the connecting rope 4 is connected to the buffer net 2 through the second rope loop 21 to improve the stability of the connection between the connecting rope 4 and the buffer net 2.
[0024] like Figure 2-4 As shown, the buffer assembly 5 includes an outer cylinder 51 and an inner cylinder 53. The inner cylinder 53 is slidably connected inside the outer cylinder 51. A pull rope 3 passes through the outer cylinder 51 and the inner cylinder 53. The pull rope 3 is fixedly connected to the outer cylinder 51 and slidably connected to the inner cylinder 53. A spring 54 is provided inside the inner cylinder 53. The two ends of the spring 54 are fixedly connected to one end of the inner cylinder 53 and the top end of the inner wall of the outer cylinder 51, respectively. A groove 52 is provided on the side wall of the outer cylinder 51. A connecting plate 55 is fixedly connected to the top end of the side wall of the inner cylinder 53. The connecting plate 55 is slidably connected inside the groove 52. One end of the connecting rope 4 is fixedly connected to the connecting plate 55. A reinforcing plate 56 is symmetrically provided at the bottom end of the connecting plate 55. One side of the reinforcing plate 56 is fixedly connected to the side wall of the inner cylinder 53.
[0025] According to the above structure, when a worker falls onto the buffer net 2, the worker's body causes the buffer net 2 to move downwards, thereby tightening the connecting rope 4. After the connecting rope 4 is tightened, it is driven by the connecting plate 55 to pull the inner cylinder 53 downwards, which in turn stretches the spring 54 to play a buffering role. During the movement of the inner cylinder 53, the connecting plate 55 slides along the slide groove 52, and the reinforcing plate 56 plays a role in strengthening the connecting plate 55 and improving the strength of the connecting plate 55.
[0026] like Figure 2As shown, the top and bottom ends of the outer cylinder 51 are both fixedly connected to the connecting cylinder 57, and the connecting cylinder 57 is fixedly connected to the pull rope 3.
[0027] According to the above structure, the connection tube 57 can improve the connection strength between the outer tube 51 and the pull rope 3.
[0028] The working principle of this utility model is as follows: When a worker falls, the worker first falls onto the buffer net 2. As the person falls, the buffer component 5 acts as a buffer, reducing the reaction force of the buffer net 2 on the worker. As the buffer net 2 descends, when the person falls into the fall arrest net 1, the fall arrest net 1 supports the person and prevents them from falling further. The pull rope 3 is connected to the fall arrest net 1 through the first rope loop 11 to improve the stability of the connection. The connecting rope 4 is connected to the buffer net 2 through the second rope loop 21 to improve the stability of the connection. The stability of the connection between the inner cylinder 51 and the buffer net 2 is ensured when a worker falls onto the buffer net 2. The worker's body causes the buffer net 2 to move downward, thereby tightening the connecting rope 4. After the connecting rope 4 is tightened, it is driven by the connecting plate 55 to pull the inner cylinder 53 downward, which in turn stretches the spring 54 to play a buffering role. During the movement of the inner cylinder 53, the connecting plate 55 slides along the slide groove 52. The reinforcing plate 56 strengthens the connecting plate 55 and increases its strength. The setting of the connecting cylinder 57 can improve the connection strength between the outer cylinder 51 and the pull rope 3.
[0029] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
