Abstract
Description
Technical Field
[0001] The embodiment of the utility model relates to the technical field of safety protection equipment, and in particular to a movable walking safety hook on a steel structure. Background Art
[0002] In recent years, with the country's substantial investment and emphasis on infrastructure construction, steel structures, as a durable and versatile building material, have been widely used in various infrastructure projects, gradually becoming the mainstream choice. The installation and welding of steel structures are essential components of current production and construction processes. To ensure the safety of workers performing high-altitude construction tasks, the most commonly used safety measure is the five-point safety harness. This harness connects to a safety rope at five points, providing comprehensive protection for workers.
[0003] However, while the five-point safety harness significantly improves the safety of aerial work, it also has some limitations. First, the use of the safety harness is limited by the length of the safety rope, which means that the worker's range of movement during work is restricted, and they cannot move freely on a large work surface. Second, the choice of safety hook attachment point also affects the worker's safe operation. In some complex steel structures, finding a reliable and secure attachment point becomes particularly difficult, which not only limits the worker's work efficiency but also may increase safety risks during the operation.
[0004] Therefore, while the five-point safety harness provides a significant degree of worker safety, its limitations are also evident. To further improve the safety and efficiency of aerial work, the development and application of more advanced safety protection equipment and technologies are necessary to address the practical limitations of existing safety harnesses. This requires not only technological innovation but also the continuous optimization of safety measures during the construction process to ensure that every aerial worker can work in a safe and reliable environment.

[0006] In order to achieve the above-mentioned purpose, according to one aspect of the utility model, a mobile walking safety hook on a steel structure is provided, including a safety anti-falling steel pipe and a limiter. Two limiters are arranged on the safety anti-falling steel pipe, and the two limiters are distributed in a symmetrical structure; the limiter includes a steel pipe adaptation structure, a walking steel wheel, and a limit hook. The safety anti-falling steel pipe is provided with a steel pipe adaptation structure, the inner end of the steel pipe adaptation structure is provided with a walking steel wheel, and a limit hook is provided below the steel pipe adaptation structure; the steel pipe adaptation structure is provided with a fastening screw.
[0007] Furthermore, a safety belt hanging ring is provided in the middle of the safety anti-fall steel pipe.
[0008] Furthermore, two pins are respectively provided at both ends of the safety anti-fall steel pipe.
[0009] Furthermore, a fixer is provided on the limit hook, and the fixer includes a screw and a stop block. The screw is threadedly connected to the limit hook, and a stop block is provided on the upper end of the screw.
[0010] Compared with the prior art, the beneficial effects of the utility model are as follows: the device solves the problem of small working area during installation and welding of steel structures and difficulty in finding safe hanging points of ordinary safety hooks; the device only needs to adjust the fastening screws to adjust the distance between the two limiters to meet the requirements of steel structures of different widths; it is easy to process and install; it has the characteristics of reasonable structure, easy disassembly, simple production, low cost, and repeated use.

DETAILED DESCRIPTION
[0018] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0019] like Figures 1 to 4 As shown, a mobile walking safety hook on a steel structure includes a safety anti-fall steel pipe 1 and a limiter 2. Two limiters 2 are mounted on the safety anti-fall steel pipe 1, and the two limiters 2 are symmetrically distributed. The limiter 2 includes a steel pipe adapter structure 3, a walking steel wheel 4, and a limit hook 5. The steel pipe adapter structure 3 is mounted on the safety anti-fall steel pipe 1, and the inner end of the steel pipe adapter structure 3 is provided with a walking steel wheel 4. The walking steel wheel 4 is rotatably connected to the steel pipe adapter structure 3. The lower end of the steel pipe adapter structure 3 is provided with a limit hook 5. The steel pipe adapter structure 3 is provided with a fastening screw 6. When the fastening screw 6 is tightened, the inner end of the fastening screw 6 abuts against the outer wall of the safety anti-fall steel pipe 1. In this embodiment, the limit hook 5 is in the shape of the letter "L", and the top of the vertical section of the limit hook 5 is fixedly connected to the steel pipe adapter structure 3, and the horizontal sections of the limit hooks 5 of the two limiters 2 are close to each other.
[0020] In actual application, two limiters 2 are installed on the safety anti-fall steel pipe 1, and the two limiters 2 are distributed in a symmetrical structure; the requirements of steel structures of different widths are met by adjusting the distance between the two limiters 2, and the safety anti-fall steel pipe 1 is cooperated to form a safety hook point structure that can be moved on the steel structure.
[0021] The structure of the steel pipe adapter structure 3 is matched with the safety anti-fall steel pipe 1. After adjusting the positions of the two limiters 2 according to the width of the steel structure, the two limiters 2 are fixed by fastening screws 6. Specifically, the specific method of adjusting the distance between the two limiters 2 is: loosen the fastening screws 6 to separate the inner ends of the limiters 2 from the outer wall of the safety anti-fall steel pipe 1, and then move the steel pipe adapter structure 3 along the axial direction of the safety anti-fall steel pipe 1. After the distance between the two limiters 2 and the steel pipe adapter structure 3 is appropriate, tighten the fastening screws 6 to make the inner ends of the limiters 2 tightly abut against the outer wall of the safety anti-fall steel pipe 1. The inner end of the steel pipe adapter structure 3 is provided with a walking steel wheel 4 rotatably connected thereto. The outer edge of the walking steel wheel 4 abuts against the steel structure, so that the entire structure can be moved on the steel structure under the drag of the operator. The limiting hook 5 below the steel pipe adapter structure 3 prevents the entire structure from detaching from the steel structure.
[0022] In this embodiment, a reinforcing rib is provided on the limiting hook 5 , and the reinforcing rib is fixed between the outer side of the limiting hook 5 and the outer wall of the steel pipe adapting structure 3 to ensure the structural strength of the limiting hook 5 .
[0023] In this embodiment, a safety belt hanging ring 7 is provided in the middle of the safety anti-fall steel pipe 1, and the safety belt hanging ring 7 is used to cooperate with the safety belt of the operator.
[0024] In this embodiment, two pins 8 are provided at both ends of the safety anti-falling steel pipe 1. When the limiters 2 are not fixed, the two pins 8 are used to prevent the two limiters 2 from sliding off the safety anti-falling steel pipe 1.
[0025] In this embodiment, a fixing device 9 is provided on the limit hook 5. The fixing device 9 includes a screw 10 and a stop block 11. The screw 10 is threadedly connected to the limit hook 5, and the upper end of the screw 10 is provided with a stop block 11. In some scenarios where the two ends of the steel structure are open structures, it is necessary to set a limiting structure at both ends of the steel structure to prevent the entire structure from sliding off the two ends of the steel structure. In this embodiment, when the fixing device 9 is used as a limiting structure, after fixing the two limiters 2 by tightening the screws 6, the screw 10 is rotated so that the stop block 11 abuts against the bottom of the flange plate of the steel structure. In this way, it is fixed to the steel structure through the mutual cooperation between the stop block 11 and the walking steel wheel 4.
[0026] At the same time, when fixed hanging points are required in some special scenarios, the entire structure can also be fixed to the steel structure through the fixer 9.
[0027] This device solves the problem of limited working area and difficulty finding safe hanging points for conventional safety hooks during installation and welding of steel structures. This device can meet the requirements of steel structures of varying widths simply by adjusting the distance between the two limiters by adjusting the fastening screws. The walking steel wheels 4 allow the entire structure to be moved on the steel structure by the operator, resolving the issue of safety belts being limited by the length of the safety rope. A fixing device 9 is provided to secure the entire structure to the steel structure when a fixed hanging point is required in special scenarios. It is also easy to process and install, and features a reasonable structure, convenient disassembly, simple production, low cost, and repeated use.
