[0015] Furthermore, the locking block has a wedge-shaped block structure.

[0016] Furthermore, each ratchet has a corresponding limiting latch at a position near the bottom of each ratchet groove; the magnetic card lock also includes a limiting latch; the limiting latch is connected to one side of the other end of the magnetic slide rod, and when the card lock block is inserted into a ratchet groove, the corresponding limiting latch is locked onto the limiting latch.

[0017] Furthermore, the fall arrestor also includes a power module; the power module is located inside the housing and is electrically connected to the electromagnetic locking device;

Detailed Implementation

[0040] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0041] like Figures 1 to 5As shown, a fall arrest device for high-altitude operations includes a fall arrestor 10 and a power-off button 20. The fall arrestor 10 includes a housing 1, a ratchet rope winding mechanism 2, a fall arrest rope 3, a double stop key 4, and an electromagnetic locking device 5. The housing 1 includes an outer shell and a cover connected to one side of the outer shell. The ratchet rope winding mechanism 2 is connected inside the housing 1. The ratchet rope winding mechanism 2 includes a ratchet 21, a main shaft, a coil spring, and a winding drum for winding the fall arrest rope 3. The connection relationships and principles between the various structures of the ratchet rope winding mechanism 2 are basically the same as those of existing speed-differential fall arrestors and are not described in detail. The fall arresting rope 3 is wound around the ratchet rope winding mechanism 2; the double stop key 4 is connected to the housing 1 and can lock with the ratchet 21 to prevent the ratchet 21 from rotating; the electromagnetic locking device 5 is located inside the housing 1; the electromagnetic locking device 5 has a magnetic locking element 51 that can be extended and moved and can lock the ratchet 21 to prevent the ratchet 21 from rotating; the power off button 20 is electrically connected to the electromagnetic locking device 5; the housing 1, ratchet 21, and fall arresting rope 3 are made of nano-ceramic aluminum alloy.

[0042] This high-altitude work fall protection device improves upon the fall arrestor 10 by adding an electromagnetic locking device 5 to the existing housing 1, ratchet rope winding mechanism 2, fall arrest rope 3, and double stop key 4. This device, combined with a power-off button 20, allows for a first layer of safety protection when a worker falls. The fall arrest rope 3 is pulled out at a significantly faster speed, causing the ratchet 21 on the ratchet rope winding mechanism 2 to shift and lock against the double stop key 4. Power is then cut off to the electromagnetic locking device 5 via the power-off button 20, allowing the magnetic locking element 51 to move and lock the ratchet 21, further preventing its rotation. This provides a second layer of safety protection. Thus, the high-altitude work fall protection device offers multiple layers of protection, achieving a superior fall protection effect. It is safe and reliable, reduces safety hazards for workers at heights, provides safety assurance for high-altitude operations, and effectively protects the lives of workers. Meanwhile, the shell 1, ratchet 21, and fall arrest rope 3 are all made of nano-ceramic aluminum alloy. The fall arrestor 10 manufactured in this way has the characteristics of light weight, high rigidity, high strength, fatigue resistance, low expansion, high damping, and high temperature resistance. When working at height, it is not easy to shake, making it more convenient to move and work. It has better quality and achieves a third layer of safety protection, which better ensures safety and provides better protection.

[0043] To facilitate observation of the magnetic card lock 51, an observation window 11 is provided on the housing 1 at the position corresponding to the ratchet 21 of the magnetic card lock 51. In this embodiment, the electromagnetic locking device 5, in addition to the magnetic card lock 51, also includes a mounting base 52, a spring 53, and an electromagnetic structure 54. The mounting base 52 is connected to the housing 1. One end of the magnetic card lock 51 is telescopically connected to the mounting base 52 via the spring 53. The electromagnetic structure 54 is provided on the housing 1 and, after being energized, is magnetically connected to one end of the magnetic card lock 51 to retract the magnetic card lock 51 away from the ratchet 21. After the electromagnetic structure 54 is energized, the electromagnet of the electromagnetic structure 54 generates magnetic force to magnetically attract the magnetic locking component 51 using the electromagnetic control principle. The spring 53 contracts, and the magnetic locking component 51 contracts away from the ratchet 21 on the mounting base 52. When it is necessary to lock the ratchet 21, the power-off button 20 de-energizes the electromagnetic structure 54. After being unlocked by power-off, the magnetic locking component 51 moves to the ratchet 21 under the action of the spring 53 and locks the ratchet 21 to stop the ratchet 21 from rotating, thus achieving a second layer of safety protection. The structure is simple and easy to operate, which is conducive to providing safe and reliable fall protection for workers at heights.

[0044] Preferably, the ratchet 21 has ratchet grooves 211 evenly distributed around its central axis; the magnetic locking component 51 includes a magnetic sliding rod 511 and a locking block 512 that can be engaged in the ratchet grooves 211 to lock the ratchet 21; one end of the magnetic sliding rod 511 is telescopically connected to the mounting base 52 via the spring 53, and the other end is connected to the locking block 512. The electromagnetic structure 54 can magnetically attract the magnetic sliding rod 511. On the mounting base 52, after the electromagnetic structure 54 is de-energized, the magnetic sliding rod 511, under the action of the spring 53, drives the locking block 512 to engage in the ratchet grooves 211 to lock the ratchet 21. More preferably, the locking block 512 is a wedge-shaped block structure. When the locking block 512 engages with the ratchet groove 211, the magnetic locking component 51 can better lock the ratchet 21, preventing the ratchet 21 from rotating, thus achieving a better fall protection effect and ensuring safety and reliability. Furthermore, the magnetic locking component 51 of this application is designed so that, within the offset range of the ratchet 21 from its normal rotation to when it engages with the double stop key in four phases, the magnetic locking component 51 can move to lock the ratchet 21 after power-off unlocking. Workers at height can, according to their needs and convenience, first de-energize the electromagnetic structure 54 to allow the magnetic locking component 51 to lock the ratchet 21, or, after a fall, when the ratchet 21 shifts and engages with the double stop key in four phases, de-energize the electromagnetic structure 54 to allow the magnetic locking component 51 to lock the ratchet 21 first. The electromagnetic locking device 5 is positioned inside the housing 1, which meets the design requirements. The requirement is that within the offset range of the ratchet 21 from normal rotation to when it locks with the double stop key 4, the magnetic locking component 51 can move the locking ratchet 21 after power failure and unlocking.

[0045] To better lock the ratchet 21, prevent its rotation, and enhance locking stability, each ratchet 21 has a corresponding limiting part 212 located near the bottom of each ratchet groove 211. The magnetic locking component 51 also includes a limiting slot 513. The limiting slot 513 is connected to one side of the other end of the magnetic sliding rod 511, and when the locking block 512 is engaged in a ratchet groove 211, the corresponding limiting part 212 locks onto the limiting slot 513. The limiting slot 513 can be U-shaped or V-shaped.

[0046] In this embodiment, the fall arrestor 10 also includes a power module 6; the power module 6 is preferably a lithium battery, which has a long service life, light weight, and is environmentally friendly, making it more suitable for use in this high-altitude work fall arrest device, thus facilitating high-altitude work fall protection. The power module 6 is located inside the housing 1 and is electrically connected to the electromagnetic locking device 5; the high-altitude work fall arrest device also includes a safety belt 30, a safety rope 40, and a conductive wire 50; the safety belt 30 is connected to the fall arrest rope 3 through the safety rope 40; one end of the conductive wire 50 is connected to the power-off button 20, and the other end passes through the interior of the safety belt 30 and is connected to the power module 6. The safety rope 40 is improved to facilitate the passage of the conductive wire 50 and to conceal the conductive wire 50, which is beneficial for high-altitude workers. Specifically, the safety rope 40 has a self-locking safety buckle 401, a buffer rope 402, and a connecting rope 403 connected in sequence; the self-locking safety buckle 401 is connected to the fall arrest rope 3; the connecting rope 403 is connected to the safety belt 30; the buffer rope 402 and the connecting rope 403 have conductor cavities through which the conductive wire 50 can pass. The conductive wire 50 of this application has good mechanical properties and can withstand an impact force greater than 2949N. When a worker falls from a height, it is not easily torn due to excessive impact force during the fall, and it has strong tensile strength.

[0047] Preferably, both the buffer rope 402 and the connecting rope 403 include a nano-ceramic aluminum alloy braided layer 60 and a high-strength polyester layer 70 wrapped around the nano-ceramic aluminum alloy braided layer 60. Combining the nano-ceramic aluminum alloy braided layer 60 and the high-strength polyester layer 70 to form the buffer rope 402 and the connecting rope 403 results in the buffer rope 402 and the connecting rope 403 being lightweight, high-rigidity, high-strength, fatigue-resistant, low-expansion, high-damping, and high-temperature resistant, making them convenient for high-altitude workers. During high-altitude operations, they are less prone to swaying, making movement easier, improving quality, enhancing safety protection, and providing better fall protection.

[0048] To better protect the conductive wire 50 and prevent damage to it due to instantaneous pulling during a fall from a height, the length of the conductive wire 50 is longer than the length of the safety rope 40. The end of the conductive wire 50 near the housing 1 has a wire buffer section 501 that is detachably electrically connected to the output end of the power module 6. Preferably, the length of the wire buffer section 501 is 0.2-0.5m. By setting the wire buffer section 501, the protection of the conductive wire 50 is improved, while optimizing its range and avoiding interference with high-altitude operations. The detachable electrical connection between the wire buffer section 501 and the power module 6 is an existing connection method. By adding existing detachable structures, such as snap-fit ​​structures, to further improve the stability of the electrical connection between the wire buffer section 501 and the power module 6, the electromagnetic structure 54, the power module 6, the conductive wire 50, and the power-off button 20 form a circuit loop that can be switched on and off.

[0049] It should be noted that the power-off button 20, electromagnetic structure 54, and self-locking safety buckle 401 are general standard parts or structures known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods. The housing 1, ratchet rope winding mechanism 2, fall arrest rope 3, double stop key 4, buffer rope 402, connecting rope 403, magnetic card lock 51, conductive wire 50, and other structures of this application all meet the requirements for appearance quality, mechanical properties, and drop test of fall arrest devices. They have good tensile strength, are not easily torn, and have reached the safety standards for the structure of existing fall arrest devices.

[0050] This invention also provides a method for using a fall protection device for working at heights, which is implemented using the aforementioned fall protection device for working at heights; the method for using the fall protection device for working at heights includes the following steps:

[0051] Step 1: Install the fall protection device for working at height in a stable manner and conduct an overall visual inspection of the fall protection device for working at height.

[0052] Step 2: Before starting work, fix the fall arrestor 10 at a low position, pull out the fall arrestor rope 3 instantly, and check whether the double stop key 4 securely locks the ratchet 21 so that the fall arrestor rope 3 cannot be pulled out; after the double stop key 4 locks the ratchet 21, press the power off button 20 to cut off the power, and check whether the magnetic locking component 51 moves to lock the ratchet 21 to stop the ratchet 21 from rotating after the power is cut off and unlocked.

[0053] Within the offset range of the ratchet 21 from normal rotation to when it locks with the double stop key 4 phase, the magnetic card lock 51 can move the lock ratchet 21 after power failure and unlocking.

[0054] Step 3: Fix the fall arrestor 10 above the work point, and then pull out the fall arrestor rope 3 inside the fall arrestor 10 at will. Work at a certain position and when the person moves upward, the fall arrestor rope 3 will automatically retract into the ratchet rope winding mechanism 2.

[0055] By adopting the above-mentioned method of using the fall protection device for high-altitude operations, the safety of high-altitude workers is enhanced, the risk of falls during high-altitude operations is reduced, and safety is provided for high-altitude operations, effectively protecting the lives of workers.

[0056] In summary, the embodiments of the present invention provide a fall protection device for high-altitude operations and its method of use, which has the following advantages:

[0057] I. This invention improves the fall arrestor 10 by adding an electromagnetic locking device 5 to the housing 1, ratchet rope winding mechanism 2, fall arrestor rope 3, and double stop key 4. This device, combined with the power-off button 20, allows for a significant increase in the pull speed of the fall arrestor rope 3 when a worker falls from height. The ratchet 21 on the ratchet rope winding mechanism 2 shifts and locks against the double stop key 4, preventing the ratchet 21 from rotating, thus achieving the first layer of safety protection. Furthermore, by de-energizing the electromagnetic locking device 5 via the power-off button 20, the magnetic locking element 51, after unlocking, moves to lock the ratchet 21, preventing its rotation, thus achieving the second layer of safety protection. Therefore, this fall arrestor provides multiple layers of protection against falls, achieving a better fall arrest effect, ensuring safety and reliability, reducing safety hazards for workers at height, providing safety assurance for high-altitude operations, and effectively protecting the lives of workers.

[0058] Second, the present invention uses nano-ceramic aluminum alloy to make the shell 1, ratchet 21 and fall arrest rope 3. The fall arrestor 10 manufactured in this way has the characteristics of light weight, high rigidity, high strength, fatigue resistance, low expansion, high damping and high temperature resistance. When working at height, it is not easy to shake, making it more convenient to move and work. The quality is better, the safety is better guaranteed and the protection is better.
