Description

Technical Field

[0001] This utility model belongs to the technical field of safety protection equipment for high-altitude operations, and specifically relates to a safety rope fixing device. Background Technology

[0002] In high-altitude operations such as construction and industrial maintenance, safety ropes are the core protective equipment for ensuring the safety of workers. When workers are working at heights, the safety rope serves as the connection between them and a fixed point. In the event of an accident, such as slipping or falling, the safety rope can support the worker's weight, preventing a direct fall to the ground and thus avoiding serious injuries or even life-threatening situations. Even if the safety rope cannot completely prevent a fall, it can significantly shorten the distance the worker falls.

[0003] To ensure the safety rope's stability, workers need to secure one end of it. Traditional methods of securing safety ropes include anchoring, weight-based fixing, clip-on fixing, and wrapping. These methods mainly rely on fixed anchor points, limiting workers' movement to a limited range. This cannot meet the needs of workers moving over a larger area. When workers need to change positions, they must constantly find new anchor points and re-secure the safety rope. Frequent snagging and unsnagging of the safety rope not only affects work efficiency but also poses a high safety risk.

[0004] While existing methods for securing safety ropes have been improved—for example, Chinese invention patent application CN111249644A describes a device for facilitating the movement of safety ropes, and Chinese utility model patent CN211434831U describes a fastening device for safety belts on loading platforms—these improvements have increased the need for workers to move over a wider area and improved work efficiency. However, these devices suffer from high friction at the anchoring point, making the safety rope movement less flexible and unable to meet the needs of frequent anchor point movements. Furthermore, they are inconvenient to maintain and increase the risk of safety accidents. Utility Model Content

[0005] This utility model provides a safety rope fixing device, which solves the problems of high moving friction of the movable safety rope anchoring part in the prior art, insufficient flexibility of the safety rope movement, inability to meet the needs of frequent anchor point movement, inconvenient maintenance, and increased risk of safety accidents.

[0006] To achieve the above objectives, this utility model provides a safety rope fixing device, including a slide rail assembly and a sliding module, wherein the sliding module is slidably mounted on the slide rail assembly, and the safety rope is fixedly connected to the sliding module;

[0007] The slide rail assembly is made of a hollow tube and has continuous grooves along its length.

[0008] The sliding module includes a spherical slider and a connecting part; the spherical slider is disposed inside the slide rail assembly, and the diameter of the spherical slider is smaller than the inner diameter of the slide rail assembly and larger than the width of the slide groove; the connecting part is used to connect the spherical slider and the safety rope;

[0009] The slide rail assembly is also provided with a maintenance channel from which the spherical slider can be removed.

[0010] As described above, the safety rope securing device provided by this utility model has at least the following beneficial effects:

[0011] This safety rope fixing device adopts a combination design of hollow slide rail and spherical slider. The rolling friction between the slide rail and the spherical slider is smaller than the sliding friction generated between the slide rail assembly and the sliding module in the existing technical solution. The safety rope can move along the slide groove more quickly and flexibly, meeting the needs of frequent anchor point movement. At the same time, by setting up a maintenance channel, not only can the wear of the spherical slider be observed in time, but also the spherical slider can be quickly replaced after wear without damaging the slide rail assembly. Furthermore, the number of spherical sliders can be quickly and conveniently adjusted according to the operation requirements. Attached Figure Description

[0018] The technical solutions of the present utility model will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present utility model.

[0019] The structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and to facilitate understanding and reading of the invention. They are not intended to limit the implementation of this invention. The terminology used in this invention is solely for describing specific embodiments and is not intended to limit the invention. For example, terms such as "upper," "lower," "left," and "right," indicating orientation or positional relationships, are based solely on the orientations or positional relationships shown in the drawings and are used only for ease of description and simplification. They do not indicate or imply that the device / structure referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0020] Those skilled in the art will understand that, without conflict, the features in the following embodiments and implementations can be combined with each other.

[0021] Please see Figure 1 and Figure 2 This utility model provides a safety rope fixing device. Like the prior art, it includes a slide rail assembly 1 and a sliding module to facilitate the movement of the safety rope. The sliding module is slidably mounted on the slide rail assembly 1, and the safety rope is fixed to the sliding module. The difference from the prior art is that:

[0022] like Figure 2 As shown, the slide rail assembly 1 is composed of a hollow tube body, and has continuous slide grooves 3 along its length.

[0023] like Figure 2 As shown, the sliding module includes a spherical slider 2 and a connecting part 5. The spherical slider 2 is disposed inside the slide rail assembly 1. The diameter of the spherical slider 2 is smaller than the inner diameter of the slide rail assembly 1 and larger than the width of the slide groove 3, ensuring that the spherical slider 2 will not fall out of the slide groove 3 while moving inside the slide rail assembly 1. The connecting part 5 is used to connect the spherical slider 2 and the safety rope. The safety rope will move with the movement of the spherical slider 2, so that the operator does not need to frequently attach and detach the safety rope. This safety rope fixing device, through the combination design of the hollow slide rail and the spherical slider 2, has a lower rolling friction between the slide rail and the spherical slider 2 compared with the sliding friction generated by the cooperation between the slide rail assembly 1 and the sliding module in the prior art. The safety rope can move more quickly and flexibly along the slide groove 3, meeting the operational needs of frequent anchor point movement.

[0024] like Figure 1As shown, the slide rail assembly 1 is also provided with a maintenance channel 4, through which the spherical slider 2 can be removed. By providing the maintenance channel 4, this safety rope fixing device can not only observe the wear of the spherical slider 2 in a timely manner, but also quickly replace it after the spherical slider 2 wears out without damaging the slide rail assembly 1. Furthermore, the number of spherical sliders 2 can be quickly and conveniently adjusted according to the work requirements.

[0025] In summary, this safety rope fixing device solves the problems of high friction during the movement of the movable safety rope anchoring part in the existing technology, insufficient flexibility in the movement of the safety rope, inability to meet the needs of frequent anchor point movements, inconvenient maintenance, and increased risk of safety accidents.

[0026] In another implementation, please refer to Figure 3 The slide 3 includes a first slide 31 and a second slide 32, which intersect in an X-shape within the slide rail assembly 1. When at least two spherical sliders 2 are placed within the slide rail assembly 1, the spherical sliders 2 can move simultaneously and in parallel via the first slide 31 and the second slide 32, respectively. Furthermore, when multiple spherical sliders 2 move within the same slide 3, they can interchange positions in the X-shaped intersection area of ​​the two slide 3s in the middle. The safety rope fixing device in this embodiment is suitable for scenarios where multiple people work simultaneously, allowing for convenient and safe movement without removing the safety rope, and enabling changes in front and back positions.

[0027] In another implementation, please refer to Figure 1 The slide rail assembly 1 is provided with a limit module at its end to close both ends of the slide rail assembly 1. The limit module is detachable. When the limit module is installed at the end of the slide rail assembly 1, the spherical slider 2 moves normally in the slide rail assembly 1. When maintenance is required inside the slide rail assembly 1, such as applying lubricating oil, the limit module is removed. This not only ensures the working safety of the device, but also further improves the maintainability of the device.

[0028] In another implementation, please refer to Figure 1 The maintenance channel 4 is a hole, and its diameter is larger than that of the spherical slider 2. More specifically, the diameter of the hole is twice the diameter of the spherical slider 2, making it easy to remove. At the same time, compared with opening a long strip-shaped maintenance channel 4, the structure of this embodiment can reduce the possibility of foreign objects entering the slide rail assembly 1, thereby improving the working reliability of this safety rope fixing device. Because the maintenance channel 4 is a hole, in order to ensure that the spherical slider 2 can be removed or observed from multiple positions of the slide rail assembly 1, multiple maintenance channels 4 are provided and are discretely arranged along the length direction of the slide rail assembly 1.

[0029] In another implementation, please refer to Figure 1 The maintenance channel 4 is equipped with a sealing cover, which closes the maintenance channel 4 under normal working conditions, thereby preventing foreign objects from entering the slide rail assembly 1 and further improving the working reliability of this safety rope fixing device.

[0030] In another implementation, please refer to Figure 2 One end of the connecting part 5 is fixedly connected to the spherical slider 2, and the other end passes through the slide groove 3 and extends to the outside of the slide rail assembly 1, and is fixedly connected to the safety rope. This embodiment provides a specific fixing method for the connecting part 5, which has a simple structure and is easy to process and produce.

[0031] In another implementation, please refer to Figure 2 The connecting part 5 has a fixing hole 6, and a hook is fixed to the safety rope. The hook is connected to the fixing hole 6. The connection between the fixing hole 6 and the hook is convenient to operate, and the fixing hole 6 is easier to process than other structures.

[0032] In another embodiment, the slide rail assembly 1 has a segmented structure, which allows for quick assembly as needed in application scenarios where a longer slide rail assembly 1 is required.

[0033] In other implementations, such as Figure 4 As shown, the slide rail assembly 1 is wavy along its length, which can alleviate the potential energy of falling when encountering a large vertical height difference on the working surface; of course, in addition to wavy, the slide rail assembly 1 can also be serrated, reverse semi-circular, etc. along its length, which will not be elaborated here.

[0034] In summary, this utility model employs a combination design of a hollow slide rail and a spherical slider 2. The rolling friction between the slide rail and the spherical slider 2 is significantly less than the sliding friction generated between the slide rail assembly 1 and the sliding module in existing technologies. This allows the safety rope to move more quickly and flexibly along the slide groove 3, meeting the operational requirements of frequent anchor point movements. Furthermore, by providing a maintenance channel 4, not only can the wear condition of the spherical slider 2 be observed promptly, but it can also be quickly replaced after wear without damaging the slide rail assembly 1. Moreover, workers can quickly and conveniently adjust the number of spherical sliders 2 according to operational needs. Therefore, this utility model effectively overcomes the shortcomings of existing technologies and possesses high industrial application value.

[0035] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
