Description

Technical Field

[0001] This invention relates to the field of safety equipment for high-altitude operations, specifically to a steel structure high-altitude operation safety belt and safety rope support device and its application. Background Technology

[0002] In most steel structure building construction processes, H-beams are used for the steel beams, which have advantages such as good load-bearing capacity and good cross-sectional stability. However, during the welding of the top steel beams and the laying of the roof panels, the lack of safety belt suspension points makes it impossible for workers to suspend their safety belts, causing inconvenience for high-altitude construction and posing significant safety hazards to workers at height.

[0003] Most existing safety ropes are suspended from a steel pipe or angle steel, which is welded to a crossbeam. This method not only requires welding the steel pipe first, but also requires dismantling the steel pipe or angle steel after the project is completed, which greatly increases the workload. At the same time, the movement of the safety rope usually involves setting up steel cables between multiple sets of steel pipes, allowing the safety rope to move through the steel cables. This causes the safety rope to rub against the steel cables for a long time, which can easily damage it. In addition, the single connection point between the safety rope and the steel cable makes the safety not high. Summary of the Invention

[0020] (III) Beneficial Effects

[0021] This invention provides a safety rope support device for high-altitude operations on steel structures and its application, which has the following beneficial effects:

[0022] A positioning block is fixedly connected to one side of the lower end face of the horizontal plate. A pin is provided on the lower end face of the horizontal plate, and a plug is slidably connected inside the pin. One end of a screw rod is fixedly connected to one side of the plug, and a clamping plate is fixedly connected to the lower end face of the plug. A rotating connection groove is provided on the side end face of the clamping plate, and an adjusting plate is rotatably connected inside the rotating connection groove. Both sides of the adjusting plate are rotatably connected to rotating connecting columns via transition connecting columns. An adjusting groove is provided on the inner wall of each side of the rotating connection groove, and at least one set of positioning blocks is fixedly connected inside the adjusting groove. The at least one set of positioning blocks is spaced apart inside the adjusting groove, so that the transition connecting columns and rotating connecting columns can be adjusted to enter the spaced position of at least one set of positioning blocks by pulling, thereby adjusting the adjusting plate. The position inside the moving connection groove, and the rotating surfaces of the rotating connecting column and the transition connecting column are parallel to the main body of the guardrail. Magnets are installed inside the main body of the guardrail, so that after the adjusting guardrail is rotated perpendicular to the clamping plate, the adjusting guardrail and the horizontal plate can clamp the flange of the "I"-shaped horizontal beam in the middle. The magnets ensure that the adjusting guardrail and the flange of the "I"-shaped horizontal beam are attracted. An oblique opening is provided on the side adjacent to the positioning block and the clamping plate. The "I"-shaped horizontal beam can be clamped by the positioning block, the clamping plate, and the adjusting guardrail. Then, the fixing mechanism and the "I"-shaped horizontal beam can be completely fixed by the screw rod and bolts, thus ensuring that the support device and the horizontal beam are firmly fixed, resulting in higher safety. Furthermore, the installation and removal of the support device and the horizontal beam are very convenient.

[0023] The main body of the railing is rotatably connected to the inside of the rotating connecting groove via transition connecting columns and rotating connecting columns. The transition connecting columns and rotating connecting columns extend into the adjusting groove. The rotating connecting columns are located within the interval of at least one set of positioning blocks, so that the position of the adjusting railing inside the rotating connecting groove can be adjusted. This allows it to adapt to beams of different thicknesses, making the device more adaptable and more practical.

[0024] At least one set of connecting columns on a fixing mechanism are connected by using a first connecting rod. A positioning groove is provided on the side end face of the first connecting rod. A transition connecting ring is slidably connected to the first connecting rod through the positioning groove. A second limiting ring is rotatably connected to the inner ring of the first limiting ring. One end of the second connecting rod is fixedly connected to the side end face of the first limiting ring, and the other end of the second connecting rod is fixedly connected to the side end face of the hook ring. The outer diameter of the second limiting ring is equal to the inner diameter of the first limiting ring. Two contact points between the second limiting ring and the first limiting ring are respectively penetrated by a set of rotating shafts. The contact point of the ring is equipped with a torsion spring, which keeps the second limiting ring and the first limiting ring at a 90° angle under normal conditions. By rotating the second limiting ring into the first limiting ring, the first and second limiting rings can pass through the positioning groove. By fixing one end of the safety rope to the hook ring and tying the other end to the worker, the safety rope relies on the first and second limiting rings for force. The positioning groove can slide with multiple sets of transition connecting rings, and one set of safety rope can pass through multiple sets of hook rings, so that the force of the device is distributed and the force strength is higher, thus making it safer for workers to operate.

One end of the first and second connecting rods 11 is fixedly connected to the side end face of the first limiting ring 9, and the other end of the first and second connecting rods 11 is fixedly connected to the side end face of the hook ring 12. The outer diameter of the second limiting ring 10 is equal to the inner diameter of the first limiting ring 9.

A torsion spring is provided at the contact point between the second limiting ring 10 and the first limiting ring 9, so that the second limiting ring 10 and the first limiting ring 9 maintain a 90° angle under normal conditions. By rotating the second limiting ring 10 into the first limiting ring 9, the first limiting ring 9 and the second limiting ring 10 can pass through the positioning groove 7. By fixing one end of the safety rope to the hook ring 12 and tying the other end to the worker, the safety rope is subjected to force by the first limiting ring 9 and the second limiting ring 10. Moreover, the positioning groove 7 can be slidably connected with multiple sets of transition connecting rings 6. One set of safety rope can pass through multiple sets of hook rings 12, so that the force of the device is distributed and the force strength is higher, thus making it safer for workers to operate.
