Abstract
Description
Technical Field
[0001] This utility model relates to the field of safety rope technology for roof panels, and more specifically, to a safety rope fixing device for steel structure roof panels. Background Technology
[0002] Steel structure roof panels are the core roof components of steel structure buildings. They are typically assembled using connection methods such as standing seam. They are lightweight, high-strength, and easy to install, and are widely used in the roof systems of factories, warehouses, and large stadiums. In high-altitude operations such as the installation and maintenance of steel structure roof panels, safety ropes are crucial protective equipment to ensure the safety of construction workers. Their function is to provide cushioning and traction in the event of an accidental fall. The safety rope fixing device is the core component that stably connects the safety rope to the steel structure roof panel. It must reliably cooperate with the standing seam mechanism of the roof panel to ensure that the safety rope is securely suspended, which is directly related to the operational safety of the workers.
[0003] However, existing safety rope fixing devices for steel structure roof panels are difficult to meet actual construction needs. Specifically, they have poor dimensional applicability, cannot flexibly adjust to changes in the spacing of the standing seam of the roof panels, and most devices can only be used for standing seam roof panels with fixed spacing. When the spacing of the standing seam mechanism is large, they cannot be used. At the same time, existing devices are not optimized for the suspension height of the safety rope. After the safety rope is set, it cannot meet the standard requirement of "high hanging and low use" for safety belts, which can easily lead to excessive fall distance when personnel fall, increasing safety risks and making it difficult to adapt to the safety protection needs of high-altitude operations on steel structure roof panels under different working conditions. Utility Model Content
[0004] (a) Technical problems to be solved In view of the above situation and to overcome the defects of the prior art, this utility model provides a safety rope fixing device for steel structure roof panels, which aims to solve the problems in the background art.
[0005] (II) Technical Solution To achieve the above objectives, this application provides the following technical solution: a safety rope fixing device for steel structure roof panels, comprising a first fixing bracket, a vertical pole fixedly connected to the upper surface of the right end of the first fixing bracket, a second fixing bracket fixedly connected to the bottom surface of the middle part of the right end of the first fixing bracket, an adjusting groove provided on the upper surface of the first fixing bracket, a sliding plate slidably connected inside the adjusting groove, a sliding bracket fixedly connected to the bottom surface of the sliding plate, a symmetrical first clamping plate, a second clamping plate and a fastening bolt provided on both sides of the bottom end of the second fixing bracket and both sides of the bottom end of the sliding bracket, a first nut threadedly connected to the outer surface of the left end of each fastening bolt, a retaining bolt threadedly connected to the inner wall of the sliding plate, an anti-slip pad sleeved on the outer surface of the retaining bolt, a second nut threadedly connected to the outer surface of the retaining bolt, multiple reserved holes provided on the outer surface of the vertical pole, four symmetrical rope hanging rings provided on the outer side of the vertical pole, a second bolt assembly provided inside two of the reserved holes, and a safety rope sleeved on the outer surface of one of the rope hanging rings.
[0006] The present invention is further configured such that the two sides of the second fixed bracket and the two sides of the sliding bracket are respectively in contact with the top of the two first clamping plates and the two second clamping plates close to each other on one side. The left ends of the two fastening bolts pass through the two second clamping plates, the second fixed bracket and the two first clamping plates in sequence and extend to the left side of the two first clamping plates. The left ends of the other two fastening bolts pass through the other two second clamping plates, the sliding bracket and the other two first clamping plates in sequence and extend to the left side of the other two first clamping plates. The right side of each first nut is in contact with the left side of the first clamping plate. The upper surface of the head of the fixing bolt and the bottom surface of the anti-slip pad are in contact with the bottom surface and the upper surface of the first fixed bracket, respectively. The bottom surface of the second nut is in contact with the upper surface of the anti-slip pad. An auxiliary pulling bracket is fixedly connected to the upper surface of the sliding plate, and the bottom surface of the auxiliary pulling bracket is fixedly connected to the upper surface of the sliding bracket.
[0007] The present invention is further configured such that three sets of fixing clamps are snapped onto the outer surface of the safety rope, the inner wall of each set of fixing clamps is in contact with the outer surface of the safety rope, and two symmetrical first bolt assemblies are provided on the outer side of each set of fixing clamps, the outer surface of each first bolt assembly is threadedly connected to the inner wall of the fixing clamp.
[0008] The present invention is further configured such that the four hanging rope rings are respectively located on both sides of two of the reserved holes, and each pair of hanging rope rings is fixed to the upright by means of a second bolt assembly in conjunction with the reserved holes.
[0009] The present invention is further configured such that two symmetrical stiffening ribs are fixedly connected to the bottom outer surface of the upright, and the bottom surface of each stiffening rib is fixedly connected to the upper right surface of the first fixed bracket.
[0010] (III) Beneficial Effects Compared with the prior art, the beneficial effects of this utility model are: By setting up a cooperative structure between the adjusting groove and the sliding plate, the sliding bracket can drive the first clamping plate and the second clamping plate to move along the adjusting groove. The positions of the first clamping plate and the second clamping plate can be flexibly adjusted according to the vertical locking edge spacing of the roof panel, adapting to vertical locking edge mechanisms with different spacings. This achieves effective fixing of roof panels of various sizes, avoiding the problem of being unable to adapt to vertical locking edge roof panels with different spacings due to poor size applicability. By opening multiple reserved holes on the uprights and using rope ring and bolt assemblies, appropriate reserved hole positions can be selected according to construction needs, and the rope ring can be installed at different heights on the uprights. This achieves flexible adjustment of the safety rope suspension height, meets the standard requirement of "high hanging and low use" for safety belts, reduces the fall distance when personnel fall, and avoids the problem of increased safety risks due to unreasonable safety rope suspension height.

[0016] Please see Figures 1-4 The system includes a first fixed bracket 1, with a vertical rod 6 fixedly connected to the upper right surface of the first fixed bracket 1. A second fixed bracket 4 is fixedly connected to the bottom middle of the right end of the first fixed bracket 1. An adjusting groove 14 is provided on the upper surface of the first fixed bracket 1. A sliding plate 16 is slidably connected inside the adjusting groove 14. A sliding bracket 13 is fixedly connected to the bottom surface of the sliding plate 16. A first clamping plate 2, a second clamping plate 3, and fastening bolts 2 are provided on both sides of the bottom end of the second fixed bracket 4 and on both sides of the bottom end of the sliding bracket 13, respectively. 0. Each fastening bolt 20 has a first nut 21 threadedly connected to the outer surface of its left end. The inner wall of the sliding plate 16 is threadedly connected to a retaining bolt 17. The outer surface of the retaining bolt 17 is fitted with an anti-slip pad 19. The outer surface of the retaining bolt 17 is threadedly connected to a second nut 18. The outer surface of the upright 6 has multiple reserved holes 7. The outer side of the upright 6 is provided with four symmetrical hanging rope rings 8. The interior of two of the reserved holes 7 is provided with a second bolt assembly 9. The outer surface of one of the hanging rope rings 8 is fitted with a safety rope 12.
[0017] Specifically, the first fixed bracket 1 provides the installation foundation, with the upper right surface of the first fixed bracket 1 fixed to the upright 6 and the middle bottom surface fixed to the second fixed bracket 4, forming a stable support frame. The adjusting groove 14 on the first fixed bracket 1 slides with the sliding plate 16. The sliding plate 16 drives the sliding bracket 13 on the bottom surface to move, which can adjust the distance between the sliding bracket 13 and the second fixed bracket 4. The first clamping plate 2 and the second clamping plate 3 at the bottom of the second fixed bracket 4 and the sliding bracket 13 clamp the roof panel upright locking mechanism with the fastening bolt 20 and the first nut 21. The fixing bolt 17 on the inner wall of the sliding plate 16 locks the position of the sliding plate 16 with the anti-slip pad 19 and the second nut 18. The reserved hole 7 of the upright 6 and the second bolt assembly 9 fix the hanging rope ring 8. The hanging rope ring 8 is fitted with a safety rope 12, so that the device can be adapted to upright locking mechanisms with different spacing and suspend the safety rope 12, solving the problem of poor size applicability of the existing device.
[0018] Please see Figures 1-4The two sides of the second fixed bracket 4 and the two sides of the sliding bracket 13 are respectively in contact with the top of the two first clamping plates 2 and the two second clamping plates 3 on one side. The left ends of the two fastening bolts 20 pass through the two second clamping plates 3, the second fixed bracket 4 and the two first clamping plates 2 in sequence and extend to the left side of the two first clamping plates 2. The left ends of the other two fastening bolts 20 pass through the other two second clamping plates 3, the sliding bracket 13 and the other two first clamping plates 2 in sequence and extend to the left side of the other two first clamping plates 2. The right side of each first nut 21 is in contact with the left side of the first clamping plate 2. The upper surface of the head of the fixing bolt 17 and the bottom surface of the anti-slip pad 19 are in contact with the bottom surface and the upper surface of the first fixed bracket 1, respectively. The bottom surface of the second nut 18 is in contact with the upper surface of the anti-slip pad 19. An auxiliary pulling bracket 15 is fixedly connected to the upper surface of the sliding plate 16. The bottom surface of the auxiliary pulling bracket 15 is fixedly connected to the upper surface of the sliding bracket 13.
[0019] Specifically, the sides of the second fixed bracket 4 and the sliding bracket 13 contact the first clamping plate 2 and the second clamping plate 3. The fastening bolt 20 passes through the second clamping plate 3, the second fixed bracket 4, the sliding bracket 13 and the first clamping plate 2 in sequence and is threaded to the first nut 21. Tightening the first nut 21 makes the first clamping plate 2 and the second clamping plate 3 clamp the bracket, enhancing the stability of the connection between the clamp and the bracket. The head of the fixing bolt 17 and the anti-slip pad 19 contact the bottom surface and the top surface of the first fixed bracket 1, respectively. The second nut 18 presses the anti-slip pad 19, improving the anti-slip effect of the fixing bolt 17 locking the sliding plate 16. The auxiliary pulling bracket 15 on the sliding plate 16 is fixed to the sliding bracket 13, which facilitates pushing the sliding bracket 13 to adjust its position, further optimizing the ease of installation and connection reliability of the device, and preventing the clamp from loosening or the sliding plate 16 from shifting.
[0020] Please see Figures 1-4 The outer surface of the safety rope 12 is fitted with three sets of fixing clamps 11. The inner wall of each set of fixing clamps 11 is in contact with the outer surface of the safety rope 12. Each set of fixing clamps 11 has two symmetrical first bolt assemblies 10 on its outer side. The outer surface of each first bolt assembly 10 is threaded to the inner wall of the fixing clamp 11.
[0021] Specifically, the outer surface of the safety rope 12 is clamped to the fixing clamp 11, the inner wall of the fixing clamp 11 is fitted with the safety rope 12, and the first bolt assembly 10 is threadedly connected to the inner wall of the fixing clamp 11. Tightening the first bolt assembly 10 causes the fixing clamp 11 to clamp the safety rope 12, preventing the safety rope 12 from slipping or falling off on the rope ring 8, ensuring the safety rope 12 is suspended stably, solving the problem of the existing safety rope 12 being not firmly fixed and easily shifting, and ensuring the safety of construction personnel.
[0022] Please see Figures 1-4Four hanging rope rings 8 are located on both sides of two of the reserved holes 7. Each pair of hanging rope rings 8 is fixed to the upright 6 by the second bolt assembly 9 in conjunction with the reserved hole 7.
[0023] Specifically, four rope loops 8 are located on both sides of the two reserved holes 7. The second bolt assembly 9 passes through the reserved holes 7 and the rope loops 8, fixing each pair of rope loops 8 to the upright 6. Different reserved holes 7 can be selected to install rope loops 8 according to the "high hanging, low use" requirement, and the suspension height of the safety rope 12 can be adjusted to meet the safety belt specifications, solve the problem that the existing device cannot meet the "high hanging, low use" requirement, and reduce the risk of personnel falling.
[0024] Please see Figures 1-4 Two symmetrical stiffening ribs 5 are fixedly connected to the bottom outer surface of the upright 6, and the bottom surface of each stiffening rib 5 is fixedly connected to the upper right surface of the first fixed bracket 1.
[0025] Specifically, the bottom surface of the stiffening rib 5 at the bottom of the upright 6 is fixed to the upper surface of the first fixed bracket 1. The stiffening rib 5 enhances the connection strength between the upright 6 and the first fixed bracket 1, disperses the tension of the safety rope 12 borne by the upright 6, prevents the upright 6 from bending and deforming due to excessive force, improves the overall structural stability of the device, and ensures the long-term safe use of the device.
[0026] Working principle: In use, the first fixed bracket 1, the upright 6, and the second fixed bracket 4 form a support frame. By pushing the auxiliary pull bracket 15 on the sliding plate 16, the sliding plate 16 slides along the adjustment groove 14 of the first fixed bracket 1, causing the sliding bracket 13 on the bottom surface to adjust the distance between itself and the second fixed bracket 4. After the distance is adapted to the roof panel standing edge locking mechanism, the fixing bolts 17 on the inner wall of the sliding plate 16 are tightened, and the position of the sliding plate 16 is locked with the anti-slip pad 19 and the second nut 18. Then, the first clamping plate 2 and the second clamping plate 3 at the bottom of the second fixed bracket 4 and the sliding bracket 13 are attached to the standing edge locking mechanism, and the fastening bolts 20 are used to pass through the second clamping plate in sequence. 3. After tightening the first clamp plate 2 and the first nut 21, clamp the clamp to the upright locking mechanism. Then, according to the "high hanging and low use" requirement, select the appropriate reserved hole 7 on the pole 6, fix the hanging rope ring 8 to both sides of the pole 6 through the second bolt assembly 9, put the safety rope 12 on the hanging rope ring 8, and use the fixing clamp 11 in conjunction with the first bolt assembly 10 to clamp the safety rope 12 to prevent slippage. The stiffening rib 5 at the bottom of the pole 6 enhances the connection strength between the pole 6 and the first fixed bracket 1. The whole device is stably fixed to the roof panel and the safety rope 12 is reliably suspended, which solves the problems of poor size applicability of the existing device, inability to meet the "high hanging and low use" requirement and unstable connection.
[0027] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
