Abstract
Description
Technical Field
[0001] This utility model relates to the field of safety rope fixing technology for high-altitude operations, specifically a safety rope fixing device for high-altitude operations on building exterior walls. Background Technology
[0002] Currently, safety rope securing devices are commonly used for high-altitude work on building exterior walls to ensure the safety of construction workers. Traditional securing methods typically involve directly fixing the safety rope hook to the wall with expansion bolts, or using simple metal ring structures for fixation. However, these devices have the following problems in practical use: Single-point fixation poses a high risk: Most devices rely on a single bolt or lock nut for fixation. If the nut loosens or falls off due to vibration, impact, or long-term wear, the safety rope may fail instantly, posing a serious safety hazard. Insufficient anti-loosening performance: High-altitude working environments are often accompanied by external forces such as strong winds and equipment vibrations. Traditional fixed structures have limited anti-loosening measures, and nuts are prone to loosening by self-rotation, requiring frequent inspection and maintenance, which increases the workload. Poor structural stability: The mounting base of some fixing devices (such as the base plate) is fixed with only a few screws. When the force is uneven, it is easy to cause local stress concentration, which may lead to deformation or detachment after long-term use. Insufficient weather resistance: Ordinary metal components are easily corroded by rain and ultraviolet rays in outdoor environments, leading to rust or reduced strength and affecting service life; Limited adaptability: The existing devices have a relatively simple fixing method, which makes it difficult to adapt to different wall structures or safety rope specifications, resulting in poor versatility. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model provides a safety rope fixing device for high-altitude operations on building exterior walls, thereby solving the problems mentioned in the background section.
[0004] To achieve the above objectives, this utility model provides the following technical solution: A safety rope fixing device for high-altitude operations on building exterior walls, comprising: A base plate, wherein multiple mounting holes are provided on the base plate for fixing the base plate to the wall surface using expansion nails; Anti-slip pads are placed between the base plate and the wall to prevent nuts from loosening; A U-shaped plate is vertically fixed to a base plate. A groove is formed between the two side walls of the U-shaped plate, and sliding holes are provided inside the two side walls. A threaded groove is provided in one of the sliding holes. A thimble, placed at the bottom of the groove, is used to secure the safety rope; Bolts, which pass through the sliding holes and collars of the U-shaped plate and mate with the threaded grooves, are used to provide support force; The lock nut, which mates with the exposed portion of the bolt, is used to secure the collar inside the U-shaped plate; When the lock nut comes off due to external force, the bolt and the threaded groove continue to fix the collar.
[0005] Preferably, there are four mounting holes, symmetrically distributed at the four corners of the base plate.
[0006] Preferably, the anti-slip pad is made of rubber and has anti-slip texture on its surface.
[0007] Preferably, the collar is made of stainless steel and has an anti-slip coating on its outer surface.
[0008] Preferably, the U-shaped plate is fixed to the base plate by welding.
[0009] Compared with the prior art, the beneficial effects of this utility model are: 1. The safety rope fixing device for high-altitude operations on the exterior wall of this building has a dual fixing mechanism to enhance safety. The main fixing method is through bolts and locking nuts, and the backup fixing method is through bolts and threaded grooves. This ensures that even if the locking nut comes loose due to external force, the device can still remain stable, preventing the safety rope from accidentally coming loose and significantly improving the safety of high-altitude operations.
[0010] 2. The safety rope fixing device for high-altitude operations on the exterior wall of this building features an anti-loosening design, reducing maintenance needs. The anti-slip pads (rubber material and anti-slip texture) effectively inhibit the loosening of the nuts due to vibration or impact, reducing the need for frequent inspections and tightening, and lowering maintenance costs.
[0011] 3. The safety rope fixing device for high-altitude operations on the exterior wall of this building has an optimized structure and enhanced stability. The symmetrical installation holes at the four corners ensure that the base plate is subjected to uniform force, avoids local stress concentration, and improves the reliability of wall fixing. The U-shaped plate is welded to the base plate to ensure the rigidity of the overall structure and prevents the connection from loosening after long-term use.
[0012] 4. The safety rope fixing device for high-altitude operations on the exterior wall of this building is designed to be corrosion-resistant and wear-resistant, extending its service life. The stainless steel collar and anti-slip coating are corrosion-resistant and have a strong load-bearing capacity, making them suitable for harsh outdoor environments and preventing the safety rope from slipping. The PTFE wear-resistant layer reduces friction loss and extends the life of the device.
[0013] 5. This safety rope fixing device for high-altitude operations on building exterior walls is highly adaptable and easy to install. It uses standard expansion bolts for fixing, making installation simple. It is suitable for different building exterior wall structures, and the lap design is compatible with multiple types of safety ropes, making it highly versatile. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0017] Example: Please refer to the following: Figure 1-3 , A safety rope fixing device for high-altitude operations on building exterior walls, comprising: The base plate 1 has multiple mounting holes 2 for fixing the base plate 1 to the wall using expansion nails. Anti-slip pad 3 is placed between the base plate 1 and the wall to prevent the nuts from loosening; U-shaped plate 4 is vertically fixed on base plate 1. A groove 5 is formed between the two side walls of U-shaped plate 4, and sliding holes are provided inside the two side walls. A threaded groove 6 is provided in one of the sliding holes. The collar 7 is placed at the bottom of the groove 5 to secure the safety rope; Bolt 8, passing through the sliding hole and collar 7 of U-shaped plate 4 and matching the threaded groove 6, is used to provide support force; The locking nut 9, which mates with the exposed part of the bolt 8, is used to secure the collar 7 inside the U-shaped plate 4; When the locking nut 9 falls off due to external force, the bolt 8 and the threaded groove 6 continue to fix the collar 7. Specifically, base plate 1 serves as the mounting base for the device and is fixed to the wall surface by expansion bolts passing through mounting holes 2 to ensure overall stability; Anti-slip pad 3: Located between the base plate 1 and the wall, it uses the frictional properties of rubber to prevent the bolt 8 from loosening and reduce displacement caused by vibration or external force; U-shaped plate 4: vertically welded to the base plate 1, the grooves 5 formed on its two side walls are used to accommodate the collar 7, the sliding hole allows the bolt 8 to pass through, and the threaded groove 6 of one side of the sliding hole provides an alternative fixing method; Loop 7: Serves as the fixing point for the safety rope. It is placed at the bottom of the groove 5 and is double-fixed by bolt 8 and lock nut 9. Bolt 8 and lock nut 9: Main fixing method: After the bolt 8 passes through the sliding hole of the collar 7 and the U-shaped plate 4, it is tightened with the lock nut 9 to directly fix the collar 7; Alternative fixing method: If the lock nut 9 falls off, the bolt 8 engages with the threaded groove 6, and the collar 7 can still be prevented from falling off through the threaded connection; Key innovation: Through the redundant design of the threaded groove 6 and bolt 8, even if the locking nut 9 fails, the device can still maintain the fixing function of the safety rope, thus improving the safety of high-altitude operations. In this embodiment: there are four mounting holes 2, symmetrically distributed at the four corners of the base plate 1; Specifically, the mounting holes 2, which are symmetrically distributed at the four corners, ensure that the base plate 1 is subjected to uniform force, avoid stress concentration at a single point, and enhance the reliability of wall fixing. In this embodiment: the anti-slip pad 3 is made of rubber and its surface is provided with anti-slip texture; Specifically, the rubber material and anti-slip texture increase friction through material elasticity and surface texture, further suppressing the nut from loosening due to vibration; In the embodiment: the collar 7 is made of stainless steel and its outer surface is provided with an anti-slip coating; Specifically, stainless steel is corrosion-resistant and has a strong load-bearing capacity, making it suitable for harsh outdoor environments. Anti-slip coating: Increases friction between the safety rope and the loop 7 to prevent the rope from slipping or coming off; In this embodiment: the U-shaped plate 4 is fixed to the base plate 1 by welding; Specifically, welding and fixing: ensure that there is no relative displacement between the U-shaped plate 4 and the base plate 1, avoid loosening of the connection after long-term use, and improve the overall structural strength; Working principle: Before use, the base plate 1 needs to be fixed to the wall. Using traditional installation methods, expansion bolts and other components are used in conjunction with the mounting holes 2 to fix the base plate 1. The anti-slip pad 3 is used to prevent the nut from slipping and loosening due to vibration. First, place the collar 7 at the bottom of the groove 5, and then pass the bolt 8 through the sliding hole opened inside the U-shaped plate 4. The sliding hole on the left side is provided with a threaded groove 6. The bolt 8 is passed through the collar 7 by rotation, providing support for the collar 7. When the bolt 8 passes through the sliding hole on the right side, the exposed part of the bolt 8 cooperates with the locking nut 9 to fix the collar 7 inside the U-shaped plate 4. When the locking nut 9 falls off due to external force or vibration, the bolt 8 matches the threaded groove 6 and can continue to fix the collar 7, thus fixing the collar 7. At this time, the safety rope can be fixed to the outside of the collar 7.
[0018] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
