Abstract
Description
Technical Field
[0001] This utility model belongs to the field of lifeline structure technology, and in particular relates to a lifeline safety protection device that does not require unhooking. Background Technology
[0002] In construction, a lifeline refers to the protective measures installed to ensure the safety of workers during high-altitude operations. Lifelines primarily consist of flexible materials such as wire ropes, fiber ropes, or webbing, used to prevent falls from heights. Their main purpose is to prevent workers from directly hitting the ground upon falling, thereby reducing injury. Lifelines must possess sufficient strength and stability to withstand the impact of a fall, ensuring the safety of workers.
[0003] Lifelines typically consist of a main lifeline running around the perimeter of a building. Workers attach their safety ropes to this main lifeline using safety locks. To enhance stability, the main lifeline is often supported by brackets at intervals. When the safety lock reaches the vicinity of a bracket while being pulled by the safety rope, it must be unlocked and reattached to pass through the bracket. During this process, workers lack adequate protection, posing a safety risk. Utility Model Content
[0004] This utility model provides a safety protection device for lifeline without removing the hook, which aims to solve the problem that the current safety lock needs to be unlocked and re-hooked when passing through the support frame, and there is a certain safety risk to the workers due to the lack of protection during this process.
[0005] This utility model is implemented as follows: a lifeline safety protection device that does not require removal of the hook, comprising:
[0006] A bracket and a lifeline, wherein the bracket includes a connecting plate and a fixing head, and several sets of brackets fix the lifeline, and the lifeline is assembled in the fixing head;
[0007] A sliding component for attaching a safety lock has a frame-shaped structure with a hollow center. The component is nested within the lifeline. The component also has a sliding opening located on its side wall, through which the hollow center communicates with the outside of the component. As the worker moves along the lifeline, the hollow center of the component passes over a support, and the component is offset from the connecting plate via the sliding opening.
[0008] Preferably, the slider is a rectangular frame structure, and the sliding opening is located on one side wall of the slider, in the middle section of the side wall.
[0009] Preferably, the sliding opening is further provided with an L-shaped reverse hook, which is located on the inner edge of the side wall of the slider, and the reverse hook and the side wall of the slider form a concave limiting area.
[0010] Preferably, the fixing head includes a first fixing ring and a second fixing ring, the second fixing ring being connected to the connecting plate by bolts, and the first fixing ring and the second fixing ring being fixedly connected by bolts.
[0011] Preferably, the inner walls of the first and second fixing rings are provided with limiting rubber pads, and the lifeline is disposed between the first and second fixing rings. When the first and second fixing rings are connected, the limiting rubber pads abut against the lifeline.
[0012] Preferably, the second fixing ring has a fixed sleeve, and the first fixing ring has a fixing rod. When the first fixing ring and the second fixing ring are connected, the fixing rod is inserted into the fixed sleeve, and the end of the lifeline is connected to the fixing rod.
[0013] Preferably, there are two sets of fixing rods and fixing sleeves, and the lifelines that need to be connected are fixed on different fixing rods.
[0014] Compared with the prior art, the embodiments of this application have the following main advantages:
[0015] The lifeline safety protection device provided by this utility model uses a sliding member to replace the safety lock of the safety rope connected to the body. When it encounters a support bracket for the lifeline, the sliding member offsets the connecting plate with the sliding port, allowing the sliding member to pass through the bracket in a staggered manner due to its own structural characteristics. This reduces the need for the safety lock to unlock near the lifeline and provides safety during movement. Attached Figure Description

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.
[0025] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0026] This utility model embodiment provides a lifeline safety protection device that does not require unhooking, such as Figures 1-6 As shown, the lifeline safety protection device that does not require removal of the hook includes:
[0027] The bracket 200 and the lifeline 300 are provided. The bracket 200 includes a connecting plate 220 and a fixing head 210. Several sets of brackets 200 fix the lifeline 300, and the lifeline 300 is assembled in the fixing head 210.
[0028] The sliding component 100 has a frame-shaped structure with a hollow center. The worker attaches the safety buckle of the safety rope connecting the body part to the sliding component 100, and the sliding component 100 is nested on the lifeline 300.
[0029] The slider 100 is also provided with a sliding opening 101, which penetrates the side wall of the slider 100. The hollow area is connected to the outside of the slider 100 through the sliding opening 101. When the worker moves along the lifeline 300, the hollow area of the slider 100 passes through the support 200, and the slider 100 is offset from the connecting plate 220 by means of the sliding opening 101.
[0030] In this application, the slider 100 replaces the safety buckle of the safety rope connecting the body part and slides on the lifeline 300. When it encounters the support bracket 200 supporting the lifeline, the slider 100 offsets the connecting plate 220 by means of the sliding port 101, allowing the slider 100 to pass through the support bracket 200 by offsetting its own structural characteristics. This reduces the need for the safety buckle to be unable to unlock through the lifeline 300 near the support bracket 200, and provides safety during movement. The slider 100 in this application adopts a square frame structure, and the sliding port 101 is located in the middle of one side frame of the slider 100. In order to reduce slippage, the sliding port 101 cannot be located in the corner area of the slider 100.
[0031] As a preferred embodiment of this example, the sliding opening 101 is further provided with an L-shaped reverse hook 110. The reverse hook 110 is located on the inner edge of the side wall of the sliding member 100, and the reverse hook 110 and the side wall of the sliding member 100 form a concave limiting area.
[0032] In this embodiment, the concave limiting area can increase the risk of the lifeline 300 and the safety lock slipping off from the sliding opening 101 during movement, thereby enhancing the safety of the slider 100. Figure 1 As shown, under the influence of gravity and tension, the lifeline 300 and the safety buckle are usually located at opposite corners of the slider 100, which are not adjacent to each other. The slider 100 has a sliding opening 101 on the side wall near the connecting plate 220. During movement, the support of gravity and the lifeline 300 makes it difficult for the lifeline 300 and the safety buckle to approach the sliding opening 101. The reverse hook 110 further prevents the lifeline 300 and the safety buckle from sliding directly to the vicinity of the sliding opening 101 by adding a concave limiting area.
[0033] In a preferred embodiment of this invention, the fixing head 210 includes a first fixing ring 211 and a second fixing ring 212. The second fixing ring 212 is connected to the connecting plate 220 by bolts, and the first fixing ring 211 and the second fixing ring 212 are fixedly connected by bolts.
[0034] The inner walls of the first fixing ring 211 and the second fixing ring 212 are provided with limiting rubber pads 230. The lifeline 300 is disposed between the first fixing ring 211 and the second fixing ring 212. When the first fixing ring 211 and the second fixing ring 212 are connected, the limiting rubber pads 230 abut against the lifeline 300.
[0035] In this embodiment, the fixing head 210 mainly provides fixing support and limiting for the lifeline 300; the limiting rubber pad 230 abuts against the lifeline 300 to reduce friction and shaking between the lifeline 300 and the bracket 200;
[0036] In a preferred embodiment of this invention, the fixing head 210 includes a first fixing ring 211 and a second fixing ring 212. The second fixing ring 212 is connected to the connecting plate 220 by bolts, and the first fixing ring 211 and the second fixing ring 212 are fixedly connected by bolts.
[0037] The second fixing ring 212 is fixed with a sleeve 241, and the first fixing ring 211 is provided with a fixing rod 242. When the first fixing ring 211 and the second fixing ring 212 are connected, the fixing rod 242 is inserted into the fixing sleeve 241, and the end of the lifeline 300 is connected to the fixing rod 242. There are two sets of fixing rods 242 and fixing sleeves 241, and the lifelines 300 that need to be connected are fixed on different fixing rods 242 respectively.
[0038] In this embodiment, the fixing head 210 helps to connect and fix the two sets of lifelines 300 that need to be connected. The lifelines 300 are fixed by passing around different fixing rods 242 and with the help of the auxiliary locking structure. Usually, the lifelines 300 are locked by passing around the fixing rods 242 and then using rope locks. The locks are not limited in this application. Any rope and fixing rod lock structure that can be completed by existing technology and equipment can be used.
