Example 1
[0032] See also Figures 1 to 3 A high-altitude safety hook comprises a support hook 2 and a rotating lifting ring 3. The support hook 2 is made of metal. The lifting ring is installed under the support hook 2 by a screw 10 and can rotate 360°. An opening is provided on the support hook 2. An automatically opening and closing latch kit 4 is provided on the support hook 2 below the opening. When sliding on the steel cable, the latch lasso closes the opening to prevent the steel cable from falling radially, thereby improving the safety of use. When passing through the connecting bracket, it can be automatically opened to facilitate safe passage. A safety protection component 5 is provided between the latch kit 4 and the support hook 2. In case of emergency on the line, professional tools can be used for emergency opening and closing to improve safety.
[0033] Specifically, the latch kit 4 includes a housing 6, a tongue lock 7 and a baffle 8. The housing 6 is mounted on the support hook 2 through a safety protection component 5. The tongue lock 7 is mounted on the baffle 8 and can slide relative to the baffle 8. The baffle 8 is fixedly mounted on the housing 6. A reset spring 9 is mounted on the tongue lock 7. A partition is provided on the baffle 8. The partition limits the spring under force compression so that the reset spring 9 drives the tongue lock 7 to reset. When in use, when the high-altitude safety hook 1 passes through the connecting bracket, the tongue lock 7 moves downward relative to the baffle 8 and compresses the spring at the same time. After passing through the connecting bracket, the tongue lock 7 is reset under the action of the spring to prevent the steel cable from being separated in the radial direction.
[0034] Furthermore, the safety protection assembly 5 includes a screw 10 and a spring pin 11. In case of emergency on the line, the safety protection assembly 5 can be opened and closed with professional tools. The safety protection assembly 5 is provided with double-layer protection. After the screw 10 is loosened to a suitable position, the first layer of protection is opened, and the spring pin 11 is pressed to open the second layer of protection. At this time, the latch kit 4 can be rotated and opened relative to the support hook 2, and after an opening is formed, the high-altitude safety hook 1 can be separated from the steel cable.
[0035] Furthermore, the upper support portion of the support hook is inclined to one side to form a wide portion structure, and a bent portion is formed at the inclined portion, and the support hook as a whole has a structure that is wide at the top and narrow at the bottom. When in use, the support hook can pass through a narrower fork or bracket in a vertical state, and can also pass through a wider fork or bracket in a tilted state.
[0036] A tongue-lip protector 12 is provided on the upper support portion above the opening. A wear protector 13 is also provided on the bent portion. The tongue-lip protector 12 and the wear protector 13 are connected to the support hook 2 by screws and can be replaced to extend the service life of the high-altitude safety hook 1. Example 2
[0037] A lifeline protection system, see Figure 4-6 , including a plurality of support bodies 18 and connecting brackets, wherein the plurality of connecting brackets are connected end to end by steel cables, and the high-altitude safety hook 1 can slide on the connecting brackets and the steel cables.
[0038] The connecting bracket includes one or more of a rock plate bracket assembly 19 , a wall-mounted bracket assembly 14 , a simple bracket assembly 15 , a zipline bracket assembly 16 , a fork assembly 17 and a multi-channel switching system 20 .
[0039] The support body 18 includes one or more of pillars, trees, walls, and mountains.
[0040] Specifically, the fork assembly 17 includes a three-way fork plate 21 and a connecting plate 22. The connecting plate 22 is arranged on the three fork plates of the three-way fork plate 17 and is used to connect with the cable. The width of the three-way fork plate 17 can allow the wide part above the support hook to pass smoothly. When in use, the fork assembly is connected to the cable, and the support hook can be tilted to use its wide part to Figure 5 The dotted line shown passes through the direction to achieve the effect of reversing.
[0041] Specifically, the multi-channel reversing system 20 includes a clamp bracket 23 and a fixed plate 24, the fixed plate is connected to the clamp bracket 23 through a connecting support plate, a plurality of mounting plates 25 are installed on the fixed plate 24 by screws, and a plurality of baffles 26 are also installed on the fixed plate 24. When in use, the multi-channel reversing system is installed on the support body through the clamp, the mounting plate is connected to the cable, and the opening of the support hook can pass through the fixed plate and the mounting plate to achieve the reversing effect. The design feature of the support hook of the present application is wide at the top and narrow at the bottom, which matches the bracket divider. When the support hook passes through a three-way or multi-way divider, the hook passing width is increased by tilting the hook angle to achieve the direction selection function.
[0042] When in use, personal PPE is hung on the rotating ring of the support hook and connected to the high-altitude safety hook. The high-altitude safety hook is hung on the steel cable line. The high-altitude safety hook moves forward with the experiencer on the steel cable line to provide uninterrupted protection and protection throughout the entire process.
