Description

Technical Field

[0001] This invention relates to the technical field of fall protection devices, and more particularly to a hanging device for fall protection devices. Background Technology

[0002] During regular maintenance of power transmission line towers, workers need to climb the tower openings to perform high-altitude operations, and these workers must wear appropriate fall protection equipment before climbing the tower.

[0003] Currently, fall arrestor systems are mainly installed manually or by drone. Manual installation requires experienced tower climbers to pre-install the fall arrestor on the tower in an unprotected state, which poses a very high safety risk to the installers.

[0004] When using a drone to attach a fall arrestor, a clamp is used to grip and remove the fall arrestor from its disc. During the gripping process, the clamp must be kept below the disc before the clamp can be retracted to remove the fall arrestor. When a novice is flying the drone, the clamp needs to be positioned correctly relative to the disc to remove it. The limited range of motion of the drone used by a novice can affect the success rate of attaching the fall arrestor using the drone. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a lower attachment device for a fall arrestor to increase the difficulty for beginners to attach fall arrestors and improve the success rate of beginners attaching fall arrestors to drones.

[0006] Based on the technical problems existing in the background art, the present invention proposes a lower hanging device for a fall arrestor, including a fall arrestor mechanism, a hanging mechanism, and a lifting mechanism. The lifting mechanism includes a limiting part and a connecting part. The limiting part is installed on the fall arrestor mechanism through the connecting part. The hanging mechanism is provided with two adjustable opening and closing claws. The two claws form an annular upper ring frame with an opening. A lower ring frame is installed at the bottom end of the hanging mechanism. A funnel-shaped flexible connecting part is installed between the lower ring frame and the upper ring frame. The limiting part is located inside the flexible connecting part and the limiting part is larger than the diameter of the lower ring frame.

[0007] Preferably, the hanging mechanism is further provided with an adjustment structure, which can adjust the opening and closing of the two grippers on the hanging mechanism.

[0008] Preferably, the gripper includes a first gripper and a second gripper, with the first gripper located above the second gripper, and both the first gripper and the second gripper being circumferentially slidably mounted on the hanging mechanism.

[0009] Preferably, a sliding rod is installed on both the first and second grippers, and a stabilizing component is provided on the hanging mechanism, with the sliding rod slidably mounted on the stabilizing component.

[0010] Preferably, the diameter of the upper ring frame is greater than the width of the limiting part.

[0011] Preferably, the fall arrestor includes a hook frame and a rotating claw, the rotating claw being rotatably mounted on the hook frame, and the axis of rotation of the rotating claw relative to the hook frame being horizontal.

[0012] Preferably, an elastic element is installed between the rotating claw and the hook frame, the elastic element allowing the rotating claw to be in an open state on the hook frame.

[0013] Preferably, the hanging mechanism has a mounting frame, the stabilizing component is mounted on the mounting frame, and the first gripper and the second gripper are both circumferentially slidably mounted on the stabilizing component and driven by the driving component.

[0014] Preferably, the slide bar includes a first slide bar and a second slide bar, the first slide bar is installed on the outer ring side of the first gripper, and the second slide bar is installed on the inner ring side of the second gripper. Both the first slide bar and the second slide bar pass through the stabilizing component and are slidably connected.

[0015] Compared with the prior art, the lower hanging device for fall arrestor proposed in this invention adopts the above-mentioned technical solution and achieves the following technical effects:

[0016] This invention can increase the success rate of novice users in lowering the fall arrest mechanism, and at the same time make it easier for construction workers to lower the fall arrest device, thereby improving the success rate during the lowering process. The hanging mechanism can guide the limiting part to ensure the success rate of lowering. Attached Figure Description

[0022] Example

[0023] Please refer to Figures 1-2 This invention proposes a lower hanging device for a fall arrestor, including a fall arrestor mechanism 1, a hanging mechanism 2, and a lifting device 3. The hanging mechanism 2 is equipped with two adjustable grippers that form an upper ring frame with an opening. The two grippers can open and close on the hanging mechanism 2. When closed, they form a ring, but the ends of the two grippers do not contact each other, thus not forming a closed loop. A lower ring frame 4 is installed at the bottom of the hanging mechanism 2. A funnel-shaped flexible connecting part 32 is installed between the lower ring frame 4 and the grippers. The diameter of the upper ring frame is larger than that of the lower ring frame 4. The flexible connecting part 32 can guide objects within the funnel. The upper and lower ring frames 4 provide support for the flexible connection part 32. The lifting mechanism 3 includes a limiting part 31 and a connecting part 32. The limiting part 31 is installed on the fall protection mechanism 1 through the connecting part 32, and the limiting part 31 is located inside the flexible connection part 32. During use, the opening and closing of the upper ring frame is controlled by adjusting the two grippers. When the limiting part 31 is located inside the upper ring frame from a top view, and the limiting part 31 is located at the upper end of the lower ring frame 4, the upward movement of the funnel will guide the limiting part 31 onto the lower ring frame 4. The entire funnel or lower ring frame 4 supports the limiting part 31, realizing the hanging effect of the fall protection mechanism 1. The limiting part 31 is larger than the diameter of the lower ring frame 4.

[0024] In a specific embodiment, refer to Figures 1-2The hanging mechanism 2 is also provided with an adjustment mechanism 55. The adjustment mechanism 5 can adjust the opening and closing between the two grippers on the hanging mechanism 2. The adjustment mechanism 5 can control the opening and closing of the two grippers. When in use, it can facilitate the inclusion of the limiting part 31 within the flexible connecting part 32.

[0025] In a specific embodiment, refer to Figures 1-2 The gripper includes a first gripper 61 and a second gripper 62. The first gripper 61 is located above the second gripper 62, and both the first gripper 61 and the second gripper 62 are slidably mounted on the hanging mechanism 2 in a ring shape. When the first gripper 61 is above the second gripper 62, the sliding of the first gripper 61 and the second gripper 62 will not affect each other, and the first gripper 61 and the second gripper 62 can form a ring-shaped upper ring frame when viewed from above.

[0026] In a specific embodiment, refer to Figures 1-2 Both the first gripper 61 and the second gripper 62 are equipped with sliding rods. The hanging mechanism 2 is provided with a stabilizing component 21. There are two stabilizing components 21 in this invention. The sliding rod can improve the stability of the first gripper 61 or the second gripper 62, so that the first gripper 61 or the second gripper 62 can slide smoothly on the hanging mechanism 2. The sliding rod is slidably installed on the stabilizing component 21.

[0027] In a specific embodiment, refer to Figures 1-2 The diameter of the upper ring frame is larger than the width of the limiting part 31. If the limiting part 31 is above the upper ring frame, it may not be possible for the limiting part 31 to move below the upper ring frame. Therefore, this situation can be avoided when the diameter of the upper ring frame is larger than the width of the limiting part 31 in the horizontal direction.

[0028] In a specific embodiment, refer to Figures 1-2 The fall arrestor 1 includes a hook frame 11 and a rotating claw 12. The rotating claw 12 is rotatably mounted on the hook frame 11, and the axis of rotation of the rotating claw 12 relative to the hook frame 11 is horizontal.

[0029] In a specific embodiment, refer to Figures 1-2 An elastic element 13 is installed between the rotating claw 12 and the hook frame 11. The elastic element 13 allows the rotating claw 12 to be in an open state on the hook frame 11. When the fall arrestor is being hung, the rotating claw 12 can be in an open state with the hook frame 11 under the action of the elastic element 13, preventing the rotating claw 12 from closing and causing the hanging to fail. At the same time, during the hanging process, the rotating claw 12 can provide assistance when it is open on the hook frame 11, preventing the hook frame 11 from failing to hang.

[0030] In a specific embodiment, refer to Figures 1-2The mounting mechanism 2 has a mounting bracket 22, a stabilizing component 21 is mounted on the mounting bracket 22, and a first gripper 61 and a second gripper 62 are both circumferentially slidably mounted on the stabilizing component 21 and driven by a driving component. The first gripper 61 and the second gripper 62 can be driven on the stabilizing component 21 by the driving component, and the circumferential sliding axes of the first gripper 61 and the second gripper 62 are the same.

[0031] In a specific embodiment, refer to Figures 1-2 The sliding rod includes a first sliding rod 63 and a second sliding rod 64. The first sliding rod 63 is installed on the outer ring side of the first gripper 61, and the second sliding rod 64 is installed on the inner ring side of the second gripper 62. Both the first sliding rod 63 and the second sliding rod 64 pass through the stabilizing component 21 and are slidably connected. The stabilizing component 21 has two spaced connecting portions 32. The first sliding rod 63 and the second sliding rod 64 are slidably installed on the connecting portions 32. The first gripper 61 can provide a stabilizing effect under the installation relationship between the first sliding rod 63 and the stabilizing component 21, and the second gripper 62 can provide a stabilizing effect under the installation relationship between the second sliding rod 64 and the stabilizing component 21.

[0032] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
