[0002] In the field of high-altitude steel structure operations, the reliable fixation of safety ropes is crucial. Currently, the common method is to weld the safety rope device directly to the construction steel beam. Although this method is secure, it has significant drawbacks: after construction, the device must be cut to remove it, which is not only cumbersome and inefficient, but also damages the device and the steel beam, making the device completely unrecyclable and unusable, with extremely poor adaptability, resulting in resource waste and increased costs.

[0003] Therefore, there is an urgent need for a safety rope device that can quickly and firmly connect steel beams and can be easily disassembled without damage after construction. Such a design can not only meet the extreme safety requirements of high-altitude operations, but also realize the rapid installation, disassembly and repeated use of the device, significantly improving construction efficiency and device adaptability, and solving the problems of resource waste and non-reusability caused by existing welding fixing methods. Therefore, in view of the above technical problems, a safety rope device for steel structure construction is proposed here. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-6 This utility model proposes a safety rope device for steel structure construction, including a welding base 1 and a connecting rod 4. The welding base 1 serves as the fixed foundation of the entire device, and its bottom has a slot 3 for receiving the connecting rod 4. An insert plate 5 is fixedly connected to the upper side of the connecting rod 4 to form a detachable connection with the welding base 1. A hanging ring 6 is fixedly connected to the bottom of the connecting rod 4 for suspending the safety rope. A pressing mechanism is installed on the inner side of the welding base 1 to provide downward pressure. A pressure plate 9 is connected to the bottom of the pressing mechanism to achieve a locking function. A planar limiting mechanism is installed between the pressure plate 9 and the insert plate 5 to prevent rotation. A support block 18 is fixedly connected to the bottom of the insert plate 5 to bear vertical loads, and the support block 18 abuts against the inner bottom of the welding base 1 to form a stable support. A quick-release mechanism is installed on the upper side of the pressure plate 9 to achieve a quick-release function.

[0025] A welding component 2 is fixedly connected to the upper side of the welding base 1 for connection with the steel beam, and the welding component 2 is welded to the construction steel beam for permanent fixation. The insertion plate 5 and the slot 3 are matched to ensure precise alignment. The pressing mechanism includes a first compression spring 7 and a telescopic rod 8. The first compression spring 7 provides continuous clamping force, and the telescopic rod 8 ensures the vertical movement trajectory of the pressure plate 9. The first compression spring 7 and the telescopic rod 8 are fixedly connected to the inner top of the welding base 1, and the pressure plate 9 is fixedly connected to the bottom of the first compression spring 7 and the telescopic rod 8 to achieve linkage.

[0026] The planar limiting mechanism includes a rectangular groove 10, a positioning groove 11, a rectangular block 12, and a positioning block 13. The rectangular groove 10 is formed on the upper side of the insert plate 5 to create a positioning reference. The positioning groove 11 is formed on the inner side of the rectangular groove 10 to provide secondary positioning. The rectangular block 12 is fixedly connected to the bottom of the pressure plate 9 to achieve the primary positioning function. The positioning block 13 is fixedly connected to the bottom of the rectangular block 12 to enhance positioning accuracy. The positioning groove 11 and the positioning block 13 are both cylindrical structures and match to achieve precise fit. The rectangular block 12 and the rectangular groove 10 are both rectangular structures and match to ensure anti-rotation function. Furthermore, the length and width of the rectangular groove 10 and the rectangular block 12 are not equal to prevent incorrect installation.

[0027] The welding seat 1 has a slot 14 on its inner side for radial positioning. The bottom of the insert plate 5 is fixedly connected to a limiting cylinder 15 as a guide component. A conical block 16 is slidably connected to the inner side of the limiting cylinder 15 to achieve automatic centering. The conical block 16 and the slot 14 match to form a radial lock. The conical block 16 has a conical structure to facilitate sliding in. A second compression spring 17 is fixedly connected to the upper side of the conical block 16 to provide a reset elastic force. The other end of the second compression spring 17 is fixedly connected to the lower side of the insert plate 5 to form an elastic support.

[0028] The quick-release mechanism includes a pull rod 19 and a connecting plate 20. The pull rod 19 is fixedly connected to the upper side of the pressure plate 9 to transmit the operating force. The end of the pull rod 19 protrudes from the upper surface of the welding seat 1 for easy operation and is fixedly connected to the connecting plate 20 to achieve linkage. The connecting plate 20 is fixedly connected between the two sets of pull rods 19 to ensure synchronous action.

[0029] The working principle of a safety rope device for steel structure construction based on an embodiment is as follows: During installation, the insert plate 5 at the top of the connecting rod 4 is first aligned with the slot 3 at the bottom of the welding seat 1 and inserted. During insertion, the upper surface of the insert plate 5 presses against the rectangular block 12 at the bottom of the pressure plate 9, pushing the pressure plate 9 upward against the elastic force of the first compression spring 7 until the support block 18 at the bottom of the insert plate 5 contacts the inner bottom surface of the welding seat 1. At this time, the operator can control the connecting rod 4 to rotate 90 degrees. In the initial stage of rotation, the limiting cylinder 15 fixed at the bottom of the insert plate 5... The internal conical block 16, due to the pressure generated by the contact between its conical side and the inner wall of the slot 3, is forced to contract into the limiting cylinder 15, compressing the second compression spring 17, allowing it to slide into the welding seat 1. When rotated to the 90-degree position, the conical block 16 is precisely aligned with the retaining groove 14 on the inner side of the welding seat 1. The second compression spring 17 releases its elastic force, pushing the conical block 16 into the retaining groove 14, completing the initial radial positioning. At the same time, the rectangular groove 10 on the insert plate 5 also rotates to align with the rectangular block 12 at the bottom of the pressure plate 9. At this point, the compressed... The first compression spring 7 drives the pressure plate 9 to move downward, causing the rectangular block 12 to quickly embed into the rectangular groove 10. Simultaneously, the positioning block 13 at its bottom also engages with the positioning groove 11 inside the rectangular groove 10, forming a stable axial and planar lock. This structure greatly improves safety. On one hand, the rectangular block 12 engaging with the rectangular groove 10 prevents the insert plate 5 from rotating unexpectedly under gravity; on the other hand, the continuous downward pressure torque applied by the first compression spring 7 keeps the rectangular block 12 tightly against the rectangular groove 10, effectively preventing the insert plate 5 from accidentally loosening in the vertical direction. When disassembly is required, pull up the connecting plate 20 connected to the pull rod 19, which will move the pressure plate 9 upward, causing the rectangular block 12 and the positioning block 13 to disengage from the rectangular groove 10 and the positioning groove 11. Then, rotate the connecting rod 4 in the opposite direction by 90 degrees, and the conical block 16 will be pressed back into the limiting cylinder 15 and disengage from the slot 14 under the action of the inclined plane. Finally, the insert plate 5 can be pulled out vertically. This design, through the spring-driven quick automatic locking and double anti-disengagement structure, ensures extreme safety in high-altitude operations while also achieving convenient installation and disassembly.
