Abstract
Description
Technical Field
[0001] This application relates to the technical field of safety protection equipment for working at heights, and in particular to a horizontal lifeline device. Background Technology
[0002] A horizontal lifeline is a safety system used for work at heights or fall protection, and is a component of personal fall protection equipment. It consists of a horizontal, flexible or rigid cable anchored between two or more points, providing continuous fall protection for workers during movement.
[0003] Using traditional horizontal lifelines during high-altitude operations can result in significant impact forces on personnel in the event of a fall, potentially causing injury. This issue warrants improvement. Utility Model Content
[0004] The purpose of this application is to provide a horizontal lifeline device to reduce harm to personnel.
[0005] The horizontal lifeline device provided in this application adopts the following technical solution: The device includes a rope, with connectors at both ends. Each connector has a shock absorber connected to its end away from the rope, and each shock absorber has a first shock-absorbing anchor connected to its end away from the connector. The rope is connected to a plurality of second shock-absorbing anchors, all of which are located between two connectors. Both the first and second shock-absorbing anchors are used for connection to a building. The shock absorber includes a first shock-absorbing element and two connecting portions respectively disposed at both ends of the first shock-absorbing element. The first shock-absorbing element has a wavy S-shaped structure.
[0006] By adopting the above technical solution, the two ends of the rope are connected to shock absorbers and first shock-absorbing anchors via connectors. The rope is connected to several second shock-absorbing anchors, which can fix the device to the building to form a horizontal lifeline, providing continuous fall protection for workers at heights. In the event of a fall, the first shock absorber will stretch and deform under the influence of the person's weight, thus playing a role in shock absorption, cushioning, and tensioning, thereby reducing the risk of injury to personnel.
[0007] Optionally, two first shock absorbers are spaced apart on the connecting portion, with each first shock absorber having its two ends connected to the two connecting portions respectively.
[0008] By adopting the above technical solution, in the event of a fall, the first shock absorber, which is set at two intervals, will be stretched and deformed under the influence of the person's weight, which can further enhance the shock absorption, buffering and tensioning effect, and better protect the safety of personnel.
[0009] Optionally, the shock absorber is in the shape of a straight plate.
[0010] By adopting the above technical solution, the shock absorber is designed as a straight plate, which can provide sufficient tension during installation and is not easily deformed.
[0011] Optionally, the shock absorber is Z-shaped.
[0012] By adopting the above technical solution, during the fall, while the first shock absorber in the shock absorber is stretched and deformed by the person's weight, the Z part of the shock absorber will also be stretched and deformed, thereby enhancing the shock absorber's buffer deformation.
[0013] Optionally, the rope is connected to several shock-absorbing brackets. Each shock-absorbing bracket includes a connecting pipe, a connecting plate, and two second shock-absorbing components. The second shock-absorbing components have a wavy S-shaped structure. The two ends of each second shock-absorbing component are connected to the connecting pipe and the connecting plate, respectively. The rope passes through the connecting pipe, and the connecting plate is connected to the second shock-absorbing anchor.
[0014] By adopting the above technical solution, in the event of a fall, the second shock absorber will be stretched and deformed under the influence of the person's weight, and the second shock absorber will play the role of shock absorption, buffering and tensioning, thereby reducing the harm to personnel.
[0015] Optionally, the shock absorber bracket further includes a first reinforcing rib, which is located between two second shock absorbers. The two ends of each second shock absorber are respectively connected to the two ends of the first reinforcing rib, and the two ends of the first reinforcing rib are respectively connected to the connecting pipe and the connecting plate.
[0016] By adopting the above technical solution, the first reinforcing rib can not only ensure the effect of buffering and shock absorption, but also ensure the structural strength of the connecting pipe and the connecting plate.
[0017] Optionally, one end of the connecting pipe is bent.
[0018] By adopting the above technical solution, the curved connecting pipe is suitable for different terrains and building conditions, making it easier for people to safely pass through multi-angle connection points and reducing safety hazards at multi-angle connection points.
[0019] Optionally, the connecting plate is connected with a bolt, the threaded end of the bolt passing through the second shock-absorbing anchor and the connecting plate, and the bolt is threaded with a nut.
[0020] By adopting the above technical solution, when the shock absorber bracket or the second shock absorber anchor is damaged, the nut can be loosened to replace the shock absorber bracket or the second shock absorber anchor, which is relatively convenient.
[0021] Optionally, the second shock-absorbing anchor includes two mounting plates and at least two sets of third shock absorbers, with each set of third shock absorbers connected to the two mounting plates at both ends, and the third shock absorbers having a wave-like S-shaped structure.
[0022] By adopting the above technical solution, in the event of a fall, the third shock absorber will be stretched and deformed under the influence of the person's weight, and the third shock absorber will play the role of shock absorption, buffering and tensioning, thereby reducing the harm to personnel.
[0023] Optionally, the second damping anchor also includes at least two second reinforcing ribs. The number of second reinforcing ribs is the same as the number of groups of the third damping components. Each group of the third damping components corresponds one-to-one with the second reinforcing rib. The two ends of the second reinforcing rib are respectively connected to the two mounting plates. Each group of the third damping components includes two third damping components, and the second reinforcing rib is located between the two third damping components.
[0024] By adopting the above technical solution, multiple third damping components undergo tensile deformation under the influence of human weight, which further enhances the damping, cushioning, and tensioning effects, thus better protecting personnel safety. The second reinforcing rib ensures both the cushioning and damping effect and the structural strength of the two mounting plates.
[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. In the event of a fall, the first shock absorber will stretch and deform under the influence of the person's weight, thus playing a role in shock absorption, buffering, and tensioning, thereby reducing the risk of injury to personnel.
[0026] 2. Multiple third damping components undergo tensile deformation under the influence of human weight, further enhancing the damping, cushioning, and tensioning effects, thus better protecting personnel safety. The second reinforcing rib ensures both the cushioning and damping effect and the structural strength of the two mounting plates. Attached Figure Description
