Abstract
Description
Technical Field
[0001] This utility model belongs to the field of steel frame and steel structure installation technology, and in particular relates to a safety lifeline device for the construction of steel frame and steel structure workshops. Background Technology
[0002] The steel frame structure forms the main framework of the factory building. Unlike traditional concrete-cast factory buildings, the steel frame structure offers faster construction and is also detachable, allowing for relocation of the factory. During the installation of the main frame, the steel frame structure needs to be pre-assembled. This assembly requires laying corrugated steel sheets on top of the steel frame structure, making the construction process high-altitude.
[0003] To increase construction safety, safety ropes (also known as lifelines) are currently installed on the top beams of the steel frame structure. During construction, operators attach their safety belts to the safety ropes, and the safety ropes prevent falls during the operation.
[0004] The safety telescopic suspension is mounted on a bracket fixed to the top beam of the steel frame structure. The bottom of the bracket is positioned on the top beam by compression screws. However, during operation, when the tension between the operator and the bracket is not perpendicular (e.g., the operator is on one side of the bracket), the bracket experiences offset tension. This offset tension significantly reduces the bracket's stability, causing the compression screws to loosen easily. (While the bracket is more stable under perpendicular tension, the operator is walking, so the force exerted by the safety rope on the bracket is always offset.) Therefore, in actual operation, the compression screws need to be retightened after a period of use, making the process extremely cumbersome.
[0005] Furthermore, the safety rope passes through the threaded loop on the support frame, causing the rope to constantly scrape against the loop when under stress, which makes the rope prone to damage and, in severe cases, compromises its safety. Utility Model Content
[0006] Based on the above background, the purpose of this utility model is to provide a safety lifeline device for the construction of steel frame and steel structure factory buildings.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] A safety lifeline device for the construction of a steel frame steel structure factory building includes several rope frame mechanisms for installing safety ropes, and the rope frame mechanisms are anchored to the steel beams of the steel frame structure;
[0009] All rope frame mechanisms include anchor brackets, and a safety rope locking wheel structure is installed at the upper end of the anchor brackets. The safety rope and the safety rope locking wheel structure roll and rub against each other.
[0010] The lower end of the anchor bracket is fixedly connected to the main anchor structure, and the two sides of the anchor bracket are respectively hinged to the auxiliary anchor structure that cooperates with the main anchor structure.
[0011] The main anchoring structure and the auxiliary anchoring structure form a triangular support structure.
[0012] Preferably, the main anchoring structure includes a lower anchor plate welded to the bottom of the anchoring bracket, and an upper anchor plate corresponding to the lower anchor plate welded to the lower part of the anchoring bracket.
[0013] An anchor bolt is threaded onto the upper anchor plate, and an anchor seat that mates with the lower anchor plate is fixedly connected to the bottom of the anchor bolt. The anchor seat is anchored onto the steel beam of the steel frame structure.
[0014] Preferably, the auxiliary anchoring structure includes an auxiliary anchor bracket, and an upper auxiliary anchor plate and a lower auxiliary anchor plate are fixedly connected to the top and bottom of the auxiliary anchor bracket, respectively.
[0015] The upper auxiliary anchor plate is threaded with an auxiliary anchor bolt, and the bottom of the auxiliary anchor bolt is fixedly connected to an auxiliary anchor seat that cooperates with the lower auxiliary anchor plate. The auxiliary anchor seat is anchored on the steel beam of the steel frame structure.
[0016] Preferably, the upper auxiliary anchor plate is hinged with a U-shaped hinge arm, the U-shaped hinge arm is fixedly connected with an inclined support rod, and the anchor bracket is fixedly connected with a hinge frame of the hinged inclined support rod.
[0017] Preferably, a T-shaped seat is fixedly connected to the anchor bracket, and the hinge bracket is fixed on the T-shaped seat.
[0018] Preferably, a number of triangular reinforcing plates are welded between the bottom of the lower anchor plate and the top of the upper anchor plate and the anchoring bracket.
[0019] Preferably, a number of triangular reinforcing plates are welded between the bottom of the upper auxiliary anchor plate and the top of the lower auxiliary anchor plate and the auxiliary anchoring bracket.
[0020] Preferably, the safety rope locking wheel structure includes a locking wheel seat, and the locking wheel seat has a through groove;
[0021] A pair of locking rope wheels are rotatably connected within the through groove; the safety rope is limited between the locking rope wheels.
[0022] Preferably, the locking rope wheel has a pair of grooves for limiting the safety rope, and the safety rope is limited between the grooves.
[0023] This utility model has the following beneficial effects:
[0024] 1. During operation, the operator attaches a safety rope to their body. When the operator is misaligned with the main anchoring structure (i.e., positioned to the side of the rope frame mechanism), a lateral tension is applied to the rope frame mechanism. Because the main anchoring structure has auxiliary anchoring structures on both sides, stability is further enhanced with the assistance of these auxiliary anchoring structures. In other words, the triangular support structure formed by one main anchoring structure and two auxiliary anchoring structures significantly improves the stability of the rope frame mechanism. Regardless of the direction of force on the main anchoring structure, the triangular support structure maintains high stability.
[0025] 2. The locking rope pulley has a pair of grooves for limiting the safety rope, with the double-stranded safety rope positioned between these grooves. This method ensures that when the safety rope (usually nylon) is stretched, it rubs against the locking rope pulley, causing it to roll slightly. In contrast, traditional methods involve threading the safety rope through a through-hole or welded guide ring. When stretched, the rope rubs against this through-hole or guide ring, resulting in excessive rope wear and compromising safety. Attached Figure Description

[0036] Example 1
[0037] like Figure 1-5 As shown, a safety lifeline device for steel frame and steel structure factory construction includes several rope frame mechanisms for installing safety ropes. The rope frame mechanisms are anchored to the steel beams of the steel frame structure (specifically, in the same way as the existing method, the rope frame mechanisms are anchored to the top beam of the steel frame structure, specifically, they are mostly anchored to the steel beams at the top edge of the steel frame).
[0038] Specifically, each rope support mechanism includes an anchor bracket 21, and a safety rope locking wheel structure 22 is installed at the upper end of the anchor bracket 21. The safety rope 1 and the safety rope locking wheel structure 22 roll and rub against each other. The rolling friction method keeps the safety rope 1 in place, while reducing the scraping and friction of the safety rope 1, increasing the service life and safety of the safety rope 1.
[0039] The lower end of the aforementioned anchoring bracket 21 is fixedly connected to a main anchoring structure 23, and auxiliary anchoring structures 24 that cooperate with the main anchoring structure 23 are respectively hinged to both sides of the anchoring bracket 21. A triangular support structure is formed by the main anchoring structure 23 and the auxiliary anchoring structures 24.
[0040] During operation, the operator attaches a protective rope to the safety rope 1. When the operator is misaligned with the main anchoring structure 23 (i.e., positioned to the side of the rope frame mechanism), a lateral tension is applied to the rope frame mechanism. Because the main anchoring structure 23 has auxiliary anchoring structures 24 on both sides, stability is further enhanced with the assistance of these auxiliary anchoring structures 24. In other words, the triangular support structure formed by one main anchoring structure 23 and two auxiliary anchoring structures 24 significantly improves the stability of the rope frame mechanism. Regardless of the direction of force on the main anchoring structure 23, the triangular support structure maintains high stability.
[0041] Example 2
[0042] like Figure 1-5 As shown, based on the structure of Embodiment 1, the main anchoring structure 23 includes a lower anchor plate 232 welded to the bottom of the anchoring bracket 21, and an upper anchor plate 231 corresponding to the lower anchor plate 232 welded to the lower part of the anchoring bracket 21; an anchoring screw 233 is threadedly connected to the upper anchor plate 231, and an anchoring seat 2331 that cooperates with the lower anchor plate 232 is fixedly connected to the bottom of the anchoring screw 233. The anchoring seat 2331 is anchored on the steel beam of the steel frame structure.
[0043] Specifically, when the anchor bolt 233 is rotated, it gradually descends until the anchor seat 2331 is pressed against the top of the steel beam of the steel frame structure, while the lower anchor plate 232 is pressed against the bottom of the steel beam of the steel frame structure. In other words, the steel beam of the steel frame structure is clamped between the anchor seat 2331 and the lower anchor plate 232. This method greatly improves the stability of the anchoring and facilitates subsequent disassembly.
[0044] The aforementioned auxiliary anchoring structure 24 includes an auxiliary anchor bracket 241, with an upper auxiliary anchor plate and a lower auxiliary anchor plate 243 fixedly connected to its top and bottom, respectively. An auxiliary anchoring screw 233 is threaded onto the upper auxiliary anchor plate, and an auxiliary anchoring seat 2331, which mates with the lower auxiliary anchor plate 243, is fixedly connected to the bottom of the auxiliary anchoring screw 233. The auxiliary anchoring seat 2331 is anchored onto the steel beam of the steel frame structure. Similarly, the steel beam of the steel frame structure is compressed between the auxiliary anchoring seat 2331 and the lower auxiliary anchor plate 243.
[0045] The aforementioned upper auxiliary anchor plate is hinged with a U-shaped hinge arm 242 (the two sides of the U-shaped hinge arm 242 are hinged by pins). The U-shaped hinge arm 242 is fixedly connected to a diagonal support rod 244. A hinge frame 2441 (U-shaped) is fixedly connected to the hinged diagonal support rod 244 on the anchor bracket 21. Specifically, a T-shaped seat 245 is fixedly connected to the anchor bracket 21, and the hinge frame 2441 is fixed on the T-shaped seat 245 (the T-shaped seat 245 is welded to the anchor bracket 21 via a welding rod 2451). The hinge frames 2441 on the left and right sides are fixed to the side walls on both sides of the T-shaped seat 245.
[0046] During operation, after the main anchoring structure 23 is anchored, the auxiliary anchoring structure 24 is then anchored. This method forms a triangular stable anchoring structure with the main anchoring structure 23 and the auxiliary anchoring structures 24 on both sides. This ensures that when the main anchoring structure 23 is subjected to eccentric force on the left or right side, the entire triangular anchoring structure is not easy to loosen.
[0047] Several triangular reinforcing plates A are welded between the bottom of the lower anchor plate 232 and the top of the upper anchor plate 231 and the anchoring bracket 21. Similarly, several triangular reinforcing plates A are welded between the bottom of the upper auxiliary anchor plate and the top of the lower auxiliary anchor plate 243 and the auxiliary anchoring bracket 21. The triangular reinforcing plates A are arranged in right-angled triangles to increase the stability of the anchor plates.
[0048] Example 3
[0049] like Figure 1-5 As shown, based on the structure of Embodiment 2, the safety rope locking wheel structure 22 includes a locking wheel seat 221, on which a through groove is provided. A pair of locking rope wheels (the locking rope wheels are arranged vertically, specifically, the upper locking rope wheel 223 is located above the lower locking rope wheel 222) are rotatably connected within the through groove; the safety rope is limited between the upper locking rope wheel 223 and the lower locking rope wheel 222.
[0050] Meanwhile, both the upper locking sheave 223 and the lower locking sheave 222 have a pair of grooves (ring structure) for limiting the safety rope 1, and the safety rope 1 (double strand) is limited within the channel 224 formed between the grooves. This method ensures that once the safety rope 1 is stretched, during the tensioning process, it rubs against the upper locking sheave 223 and the lower locking sheave 222, causing them to roll slightly. In contrast, the traditional method involves passing the safety rope 1 through a through hole or a welded lead ring. When stretched, the safety rope 1 rubs against the through hole or the welded lead ring, resulting in excessive rope wear and compromising its safety.
[0051] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
