Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.
[0028] The embodiment provides a high-altitude work anti-falling lifeline system, which comprises a first horizontal lifeline, a second horizontal lifeline and a safety belt. Figures 1 to 8As shown, it comprises a first horizontal lifeline 1 and a second horizontal lifeline 2, the first horizontal lifeline 1 is suspended, the first horizontal lifeline 1 extends along a first horizontal operation direction, the first horizontal lifeline 1 is arranged at intervals along a second horizontal operation direction, the second horizontal operation direction is perpendicular to the first horizontal operation direction. The second horizontal lifeline 2 is used for the safety belt 3 to hang, one end of the second horizontal lifeline 2 is slidably connected to one of the first horizontal lifelines 1, the other end of the second horizontal lifeline 2 is slidably connected to another of the first horizontal lifelines 1, and the second horizontal lifeline 2 extends along the second horizontal operation direction. After the worker wearing the safety belt 3 hangs the safety belt 3 on the second horizontal lifeline 2, the second horizontal lifeline 2 is slid along the extension direction of the first horizontal lifeline 1, the operation in the first horizontal operation direction can be realized, and the safety belt 3 is slid along the extension direction of the second horizontal lifeline 2, the operation in the second horizontal operation direction can be realized, thereby improving the operation range in the second horizontal operation direction, without the worker frequently returning to the starting position to switch the first horizontal lifeline 1 for hanging, and ensuring the operation efficiency.
[0029] In actual construction, it should be noted that when the first horizontal lifeline 1 and the second horizontal lifeline 2 are arranged, they should be as straight as possible, so that the first horizontal lifeline 1 and the second horizontal lifeline 2 are arranged horizontally as a whole, so that the first horizontal lifeline 1 is parallel to the first horizontal operation direction, the second horizontal lifeline 2 is parallel to the second horizontal operation direction, and all the first horizontal lifelines 1 are at the same elevation. Of course, the above-mentioned horizontal is as close to the theoretical parallel as possible, and if there is an error, it should also be covered within the scope mentioned in the embodiment, such as the end of the horizontal lifeline being slightly higher than the other end, the depression of the middle part of the horizontal lifeline under the weight of the worker, and the above-mentioned same elevation is as close to the same elevation as possible, and if there is an error, it should also be covered within the scope mentioned in the embodiment, such as a single first horizontal lifeline 1 being slightly higher or lower than the elevation. In addition, according to some special needs, the first horizontal lifeline 1 and the second horizontal lifeline 2 can also be arranged horizontally, such as the end of the horizontal lifeline being higher than the other end, at this time, as long as the first horizontal lifeline 1 extends along the first horizontal operation direction, and the second horizontal lifeline 2 extends along the second horizontal operation direction, according to special needs, the first horizontal lifeline 1 can not be at the same elevation, as long as the first horizontal lifeline 1 is arranged at intervals along the second horizontal operation direction.
[0030] In an embodiment, as Figures 1 to 8As shown, the system includes two first horizontal lifelines 1, with one end of a second horizontal lifeline 2 sliding on one of the first horizontal lifelines 1 and the other end sliding on the other first horizontal lifeline 1. When the worker's safety belt 3 is attached to the second horizontal lifeline 2, the worker's working range in the second horizontal working direction is the distance between the two first horizontal lifelines 1 plus the maximum working range that each first horizontal lifeline 1 can reach outward along the second horizontal working direction.
[0031] In one implementation, such as Figures 1 to 8 As shown, the spacing between two first horizontal lifelines 1 is 2m to 4m. This spacing is mainly applicable to fall protection lifeline systems for high-altitude operations that contain only two first horizontal lifelines 1. If there are three or more first horizontal lifelines 1, the spacing between two adjacent first horizontal lifelines 1 can be adjusted accordingly based on the actual situation.
[0032] In one implementation, such as Figures 1 to 8 As shown, this includes three or more (covering three) first-level lifelines 1. When there are three or more first-level lifelines 1, the second-level lifeline 2 can select any two of them for sliding connection. For example... Figure 3 and Figure 7 As shown, the two ends of the second horizontal lifeline 2 are slidably connected to the first horizontal lifeline 1 at the beginning and end, respectively. Figure 4 As shown, among the three first-level lifelines 1, the two ends of the second-level lifeline 2 are selected to be slidably connected to the two adjacent first-level lifelines 1, as follows. Figure 6 As shown, among the four first-level lifelines 1, the second-level lifeline 2 skips one of them and slides to connect with the other two first-level lifelines 1. The above is just a simple example. You can choose the settings according to your needs.
[0033] When there are three or more first-level lifelines 1, the safety belt 3 should be equipped with at least two buckles to facilitate crossing a first-level lifeline 1 that is blocked in the middle during the worker's movement. Figure 3 For example, in the initial stage, after the workers fasten all the locks to the second level lifeline 2, all the locks and the workers are now located at the first level lifeline 1. Figure 3 The topmost first level lifeline 1) and the second first level lifeline 1 ( Figure 3 Located between the middle first-level lifeline 1, when workers need to move to the second first-level lifeline 1 and the third first-level lifeline 1 ( Figure 3If the first horizontal lifeline 1 at the bottom is unfastened first, the second horizontal lifeline 1 between the second first horizontal lifeline 1 and the third first horizontal lifeline 1 is fastened first, and then the remaining fasteners are fastened to the second horizontal lifeline 1 between the second first horizontal lifeline 1 and the third first horizontal lifeline 1, the worker can cross the second first horizontal lifeline 1 and move to the second first horizontal lifeline 1 and the third first horizontal lifeline 1.
[0034] In an embodiment, as shown in Figures 1 to 8 The second horizontal lifeline 2 is slidably connected to all the first horizontal lifelines 1, and a plurality of moving areas are formed between the first horizontal lifelines 1 connected to the second horizontal lifeline 2, i.e., one moving area is formed between each adjacent two first horizontal lifelines 1. At this time, at least two fasteners are arranged on the safety belt 3, and when the moving area is switched, one fastener or a plurality of fasteners are fastened to the second horizontal lifeline 2 in the moving area to be switched, and then the remaining fasteners are fastened to the second horizontal lifeline 2 in the moving area to be switched from the currently fastened moving area, so that the moving area switching can be realized.
[0035] In an embodiment, as shown in Figures 1 to 8 At least two fasteners for fastening to the second horizontal lifeline 2 are arranged on the safety belt 3. Through the cooperation of the fasteners being unfastened and fastened in sequence, the first horizontal lifeline 1 intercepted or the different moving areas formed by the first horizontal lifelines 1 can be switched. That is, part of the fasteners are unfastened to cross the first horizontal lifeline 1 intercepted, and then the remaining fasteners are unfastened to cross the first horizontal lifeline 1 intercepted and fastened to the second horizontal lifeline 2.
[0036] In an embodiment, as shown in Figures 1 to 8 The second horizontal lifeline 2 is slidably connected to the first horizontal lifeline 1 through the sliding member 5.
[0037] In an embodiment, as shown in Figures 1 to 8 The sliding member 5 is a sliding ring, a sliding sleeve, or a sliding cable pulley, etc. According to the actual demand or the commonly used sliding member in construction, the selection can be made. As a preferred, lubricating oil can be applied between the sliding member 5 and the first horizontal lifeline 1 to reduce the friction.
[0038] In an embodiment, as shown in Figures 1 to 8 The two ends of the first horizontal lifeline 1 are respectively anchored on the anchor 4, such as a wall or a column, etc.
[0039] In an embodiment, as shown in Figures 1 to 8 The first horizontal lifeline 1 and the second horizontal lifeline 2 are both steel wire ropes.
