Abstract
Description
Technical Field
[0001] This utility model relates to the field of safety technology in building installation engineering, specifically a safety rope fixing device for the installation of large-span steel structure beams. Background Technology
[0002] With the continuous development of urban construction and the increase of modern construction projects, high-altitude operations are frequent at construction sites. However, high-altitude operations are extremely risky. Once a fall occurs, it will cause serious casualties and property damage. Therefore, the correct use of safety ropes and the prevention of falls from heights are the key concerns for safety in high-altitude operations.
[0003] Currently, the most common method for securing safety ropes during high-altitude operations on large-span steel structures, both domestically and internationally, is to use rope clamps to fix the ropes by drilling holes in the steel pipe columns. This results in the safety ropes being easily worn through the holes in the steel pipe columns and the rope clamps being prone to loosening during construction, posing safety hazards. Utility Model Content
[0004] This utility model provides a safety rope fixing device for the installation of crossbeams of large-span steel structures, which can solve the problem of easy wear and loosening of existing safety rope fixing devices for high-altitude operations during the installation of large-span steel structures.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a safety rope fixing device for the installation of large-span steel structure beams, comprising a clamp installed on the beam column, a pad installed on one radial side of the clamp, an upper screw installed on the side of the pad, a first nut fitted on the upper screw, a lower guide post installed centrally below the upper screw, lower screws symmetrically arranged on the left and right sides of the lower guide post, a pressure plate fitted on the lower guide post, and a second nut installed on the lower screw passing through the pressure plate. The safety rope passes through the gap between the lower guide post and the lower screw from bottom to top, wraps around the upper screw, and then passes through the gap between the lower guide post and the lower screw from top to bottom. By setting the upper screw, lower guide post, and lower screw, the safety rope can be fixed by being threaded through from top to bottom, and the safety rope is pressed and fixed by the pressure plate. This results in minimal wear on the safety rope and makes it less prone to loosening.
[0006] Preferably, a three-hole washer is installed on the side of the pressure plate facing away from the pad. The lower guide post and the lower screw both pass through the three-hole washer. The three-hole washer can prevent the second nut from loosening and also prevent the pressure plate from sliding.
[0007] Preferably, the open end of the clamp is connected and locked by a connecting bolt and a third nut, which can ensure that the entire fixing device can be firmly fixed to the beam column.
[0008] Preferably, the clamp and the pad are fixed by full welding to ensure a firm fixation between the clamp and the pad.
[0009] Preferably, the upper screw is fitted with a washer, and the first nut presses down on the safety rope through the washer, which can press down and fix the safety rope.
[0010] Compared with the prior art, the beneficial effects of this utility model are:
[0011] Compared to conventional safety rope fixing devices, this device adopts an integrated structural design. Conventional safety rope installation involves drilling holes in steel structure columns and then fixing them with rope clamps, which can lead to safety issues such as safety rope wear and easy loosening of rope clamps. This device, by setting up an upper screw, a lower guide post, and a lower screw, allows the safety rope to be threaded and fixed from top to bottom, and the safety rope is pressed down and fixed by a pressure plate. This results in minimal wear on the safety rope and makes it less prone to loosening. Attached Figure Description

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0018] like Figure 1-3As shown, this utility model provides the following technical solution to solve the problem of easy wear and loosening of safety rope fixing during high-altitude operations in the installation of large-span steel structures: a safety rope fixing device for the installation of crossbeams of large-span steel structures, including a clamp 2 installed on the crossbeam column, a pad 1 installed on one radial side of the clamp 2, an upper screw 5 installed on the side of the pad 1, a first nut 4 sleeved on the upper screw 5, and a lower guide post 8 installed centrally below the upper screw 5, with symmetrical arrangements on the left and right sides of the lower guide post 8. There is a lower screw 6, and a pressure plate 9 is sleeved on the lower guide post 8. The lower screw 6 passes through the pressure plate 9 and is equipped with a second nut 7. The safety rope 11 passes through the gap between the lower guide post 8 and the lower screw 6 from bottom to top and goes around the upper screw 5. Then it passes through the gap between the lower guide post 8 and the lower screw 6 from top to bottom. By setting the upper screw 5, the lower guide post 8 and the lower screw 6, the safety rope 11 can be fixed by connecting the upper and lower parts. The pressure plate 9 presses down and fixes the safety rope 11. This results in very little wear on the safety rope 11 and makes it less likely to loosen.
[0019] Specifically, clamp 2 can be installed on the crossbeam column as needed, and the height can be adjusted as needed. Multiple clamps 2 can be installed on adjacent crossbeam columns. The safety ropes 11 between the safety rope fixing devices on adjacent crossbeam columns can be the same or different. After the safety ropes 11 are fixed by multiple fixing devices, they can form a continuous safety rope. The safety belts on the construction workers can be fastened to the safety rope for movement. When the safety buckle of the safety belt moves to the fixing device, it can also go around the lower screw 6 and the upper screw 5 without affecting the movement of the construction workers.
[0020] In this embodiment, as Figure 2 As shown, a three-hole washer 10 is installed on the side of the pressure plate 9 facing away from the pad plate 1. The lower guide post 8 and the lower screw 6 both pass through the three-hole washer 10. The three-hole washer 10 can prevent the second nut 7 from loosening and also prevent the pressure plate 9 from sliding.
[0021] In this embodiment, the open end of the clamp 2 is connected and locked by the connecting bolt 12 and the third nut 13, which ensures that the entire fixing device can be firmly fixed to the beam column. Moreover, the clamp 2 and the pad 1 are fixed by full welding, ensuring a firm fixation between the clamp 2 and the pad 1.
[0022] In this embodiment, a washer 3 is provided on the upper screw 5, and the first nut 4 presses down on the safety rope 11 through the washer 3, which can press down and fix the safety rope 11.
[0023] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.
[0024] Furthermore, in this utility model, the use of terms such as "first," "second," etc., is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly and specifically defined.
[0025] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0026] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
