[0015] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0016] In this document, terms such as “up,” “down,” “left,” “right,” and “top” indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0017] like Figures 1 to 4 As shown, a fall arrest device for temporary suspension includes a hanging point frame 1 for connecting to a tower. The hanging point frame 1 is provided with a connecting component for connecting a safety rope 2 and a snap-fit ​​component for attaching to the tower. The snap-fit ​​component includes a first snap-fit ​​part and a second snap-fit ​​part to achieve dual protection. A buffer part is provided between the first snap-fit ​​part and the hanging point frame 1.

[0018] This device uses a temporary suspension point at the top of the tower, with a safety rope 2 attached to it. Workers can avoid falls by attaching the safety buckle from their safety belt to the safety rope 2, thus ensuring their safety. When the suspension frame 1 is placed on the tower, if the safety rope 2 is under stress, the force is transmitted to the first locking part, which locks onto the tower to provide anchor support for the safety rope 2. A second locking part is also provided to prevent the first locking part from failing and thus ensuring the suspension point function. This gives the fall protection device a secondary safety guarantee effect. The device has a simple structure and high reliability.

[0019] In this embodiment, the first locking part is specifically a stop block. The stop block includes a locking block 4 for locking the angle steel 3 on the tower. The safety rope 2 pulls the stop block 4 close to the angle steel 3 through the connecting component, so that the locking block 4 locks with the angle steel 3 to fix the hanging point frame 1.

[0020] Specifically, the stop block can reciprocate on the hanging point frame 1. When the hanging point frame 1 is hung on the angle steel 3, the safety rope 2 is not under force. After the worker establishes a connection with the safety rope 2, he pulls the safety rope 2 and drives the stop block to move through the connecting component, so that the angle steel 3 is locked into the limiting groove formed by the snap-fit ​​block 4, thereby locking the hanging point frame 1 and the angle steel 3, i.e., the tower, and serving as an anchor point to support the safety rope 2 and the worker.

[0021] Preferably, a flexible self-locking device is provided on the safety rope 2 to facilitate the connection between the worker and the safety rope 2.

[0022] In this embodiment, the hanging frame 1 includes two parallel support plates 5, which are connected by several connecting plates 6. The stop block also includes a slider 7, which is sleeved around the guide rod 8 and slidably connected to the guide rod 8. The guide rod 8 is fixed between the two support plates 5, and the snap-fit ​​block 4 is fixedly connected below the slider 7.

[0023] Specifically, the two support plates 5 and the connecting plate 6 form the hanging point frame 1, ensuring that the hanging point frame 1 has sufficient strength. The slider 7 slides around the guide rod 8 to drive the locking block 4 to lock with the angle steel 3. The stop block is located between the two support plates 5, thereby locking with the angle steel 3 from the middle of the hanging point frame 1, so that the hanging point frame 1 is evenly stressed. At the same time, the support plates 5 on both sides play a limiting and guiding role for the stop block, ensuring the locking effect of the locking block 4 and the angle steel 3.

[0024] The support plate 5 is J-shaped and has a right-angled side that matches the right angle of the angle steel 3. After the stop block and the end of the angle steel 3 are locked together, the angle steel 3 is stably clamped between the stop block and the hanging point frame 1, thereby stably supporting the safety rope 2 and ensuring the safety of the workers.

[0025] In this embodiment, a fall arrestor for temporary suspension is provided at both ends of the guide rod 8, which are respectively fixedly connected to the hanging point frame 1. A hanging plate is provided above the slider 7. The buffer part is specifically a spring 10 connected between the left limiting block 9 and the hanging plate. A steel wire rope 11 for connecting the connecting components is provided on the other side of the hanging plate.

[0026] Two limit blocks 9 are set to stably fix the guide rod 8 on the hanging point frame 1. When the wire rope 11 pulls the stop block, the spring 10 generates the opposite tension, which buffers the sliding of the stop block on the guide rod 8 and prevents the stop block from colliding with the angle steel 3 and causing damage to the stop block. At the same time, when the wire rope 11 is not under force, the spring 10 can drive the locking block to reset, so as to detach from the angle steel 3.

[0027] In this embodiment, a guide block and a pulley are provided on the right-side limiting block 9 in the fall arrest device. The steel wire rope 11 passes through the guide block and is led out through the pulley to facilitate connection of the connecting component. A spring 10 is provided between the steel wire rope 11 and the connecting component.

[0028] A guide block is set to limit the wire rope 11 to prevent it from falling off the limit block 9. A pulley is set to change the direction of the wire rope 11 while reducing the friction of the wire rope 11 and improving its service life. A spring 10 is set between the wire rope 11 and the connecting component to buffer the wire rope 11 from both ends and prevent stress concentration and breakage caused by sudden force on the wire rope 11.

[0029] In this embodiment, the connecting assembly for the temporary suspension fall arrest device includes a U-shaped ring 12 for connecting the safety rope 2. The top two ends of the U-shaped ring 12 are rotatably connected to the movable shaft 13, and the two ends of the movable shaft 13 are slidably connected to the grooves opened on the two side support plates 5.

[0030] With the above setup, when the hanging frame 1 is placed on the angle steel 3, if the safety rope 2 is under stress, the force will first be transmitted to the stop block through the wire rope 11. After the stop block is engaged with the angle steel 3, the U-shaped ring 12 continues to descend, and the force will only be transmitted to the hanging frame 1 when it reaches the bottom of the chute. This design is simple in structure, highly reliable, and can effectively buffer the impact of the safety rope 2 on the hanging frame 1.

[0031] In this embodiment, a snap-fit ​​plate 14 is provided at the end of the hanging point frame 1. The snap-fit ​​plate 14 is located below the stop block. The second snap-fit ​​part is specifically the slot between the snap-fit ​​plate 14 and the hanging point frame 1. The angle steel 3 is snapped into the slot to prevent the hanging point from loosening when the stop block fails.

[0032] Specifically, the snap-fit ​​plate 14 is located at the hook-up end of the J-shaped support plate 5. The snap-fit ​​plate 14 is connected to the support plates 5 on both sides and extends to the inner side of the hanging point frame 1 to form a slot for snapping the angle steel 3. With the above setting, if the wire rope 11 breaks accidentally, the snap-fit ​​between the stop block and the angle steel 3 will fail. Under the tension of the safety rope 2, the hanging point frame 1 will rotate, and the angle steel 3 can be snapped into the slot, preventing the hanging point frame 1 from continuing to rotate and causing the angle steel 3 to fall off. This design has a secondary safety protection function and improves the safety of the fall arrest device.

[0033] The fall arrestor for temporary suspension in this embodiment also includes a driving mechanism for moving the hanging point frame 1 to a specified height position on the tower. The driving mechanism includes a drone 15 and a mounting component located below the drone 15 for connecting the hanging point frame 1.

[0034] Thanks to advancements in drone technology, we can use a drone 15, along with a mounting kit, to attach temporary anchor points to the top of the tower. After the work is completed, the drone 15 can also be used to remove the temporary anchor point for future use.

[0035] In this embodiment, the temporary suspension anti-fall device includes a flexible hanging rod 16 and a hook. The hook is rotatably connected to the flexible hanging rod 16 via a hook nose. A counterweight 17 is provided at the top of the hook, and a hanging point 19 is provided at the bottom of the hook for hooking onto the hanging frame 18 located above the hanging point frame 1.

[0036] Specifically, the hook includes a hook body 20 and a hook claw 21. By adjusting the counterweight 17, the hook can be in a horizontal state when unloaded, which is beneficial for the drone 15 to unhook or attach to the attachment point. When there is a load on the attachment point 19, it will cause the center of gravity to shift, causing the hook claw 21 to lift up. This can prevent the attachment point from accidentally detaching. Once the attachment point is attached to the angle iron 3, the drone 15 can detach and break free.

[0037] Preferably, the hook consists of two hook plates that are spaced apart and symmetrically arranged, and the flexible hanging rod 16 is hinged between the two hook plates. This arrangement enables the hook to have a directional function, which can prevent the hanging point from rotating randomly after being hooked, and facilitates the hanging and unhooking operations of the UAV 15 on the hanging point.

[0038] In this embodiment, in the temporary suspension anti-fall device, the mounting point 19 is located between the hook 21 and the hook body 20. There are two hooks 21 symmetrically arranged about the hook body 20, and an included angle is provided between the two hooks 21 to facilitate hooking with the hanging frame 18.

[0039] Specifically, the hook frame 18 is T-shaped and located above the hanging point frame 1. The T-shaped junction of the hook frame 18 matches the hanging point 19. The two arms of the T-shape are respectively hooked to the hook claws 21, and the force is evenly distributed. The included angle between the two hook claws 21 is set to facilitate the guidance of the vertical rod of the T-shaped hook frame 18 so that it can finally be locked into the hanging point 19. This hook has the characteristics of simple structure, compactness, reliability and easy operation.
