Description

Technical Field

[0001] This utility model relates to the technical field of safety equipment for pipeline installation, and in particular to a safety protection device for the construction of large-diameter circular pipelines. Background Technology

[0002] Large-diameter circular pipelines are commonly used in nuclear power engineering, chemical engineering, and wastewater treatment. Depending on the specific application of these pipelines, various methods are employed for their installation and connection, including supports, underground burial, and trenching. Each method corresponds to a different construction environment. Due to the pipeline's massive size, installation requires hoisting equipment, elevated construction equipment, and construction safety equipment, significantly complicating the construction environment and increasing the inherent risks. For example, ensuring worker safety is crucial. Traditionally, large-diameter circular pipeline construction involves erecting scaffolding on either side or above the pipeline. Workers use safety harnesses in conjunction with the scaffolding for safe operation. However, this method suffers from numerous intersections in the scaffolding structure, making safety harness adjustment inconvenient. Workers, while hooked to the scaffolding, cannot move freely over long distances due to these intersections, and frequent re-hooking of the safety harness is necessary when changing work positions, hindering pipeline installation efficiency. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a safety protection device for large-diameter circular pipeline construction that allows workers to move freely over a large distance on the pipeline while significantly reducing the frequency of safety belt hook adjustment, thus helping to improve pipeline construction efficiency.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a safety protection device for the construction of large-diameter circular pipes, including two protective support frames arranged opposite each other, a protective rope connecting the two protective support frames, each protective support frame including two protective support rods arranged with increasing distance from top to bottom, a support rod connecting plate provided between the top ends of the two protective support rods, the end of the protective rope being connected to the support rod connecting plate, and a support rod fixing base fixedly connected to the bottom end of each protective support rod, the support rod fixing base being detachably assembled with the pipe reinforcing ribs on the surface of the large-diameter circular pipe.

[0005] As a preferred technical solution, the support rod connecting plate is configured as a fan-shaped steel plate, and the upper part of the support rod connecting plate is provided with a rope fixing hole for connecting with the protective rope. The support rod connecting plate below the rope fixing hole is provided with at least one row of support rod connecting holes arranged in an arc. The two protective support rods can be detachably assembled onto some of the support rod connecting holes.

[0006] As a preferred technical solution, a connecting bolt is detachably provided through the connecting plate of the support rod and each of the protective support rods, and a connecting nut is provided on the connecting bolt for use.

[0007] As a preferred technical solution, the support rod fixing base includes a buckle channel steel with the port facing downward. The buckle channel steel is buckled onto the top of the pipe reinforcing rib, and an assembly locking element is movably provided on at least one side wall of the buckle channel steel.

[0008] As a preferred technical solution, at least one inner surface of the side wall of the buckle channel steel is provided with a guide slope to facilitate assembly.

[0009] As a preferred technical solution, the inner top wall of the buckle channel steel is configured as an abutting arc surface.

[0010] As an improvement to the above technical solution, the contact end between the assembly locking component and the pipe reinforcing rib is fixed with a locking anti-slip block.

[0011] Due to the adoption of the above technical solution, the safety protection device for the construction of large-diameter circular pipelines includes two opposing protective support frames, with a protective rope connecting the two protective support frames. Each protective support frame includes two protective support rods arranged with increasing distance from top to bottom. A support rod connecting plate is provided between the top ends of the two protective support rods. The end of the protective rope is connected to the support rod connecting plate. A support rod fixing base is fixedly connected to the bottom end of each protective support rod. The support rod fixing base is detachably assembled with the pipeline reinforcement rib on the surface of the large-diameter circular pipeline. This utility model has the following beneficial effects: By assembling the support rod fixing base with the pipeline reinforcement rib, the corresponding protective support rod is installed and fixed to the top of the pipeline. The protective rope is limited and connected between the two support rod connecting plates. The safety belt used by the operator during construction can be hooked onto the protective rope. The length of the protective rope can limit the range of free movement of the operator after hooking the safety rope once, eliminating the need for frequent hooking and adjustment of the safety belt, making the construction operation more flexible and convenient, and helping to improve the efficiency of pipeline construction.

[0019] like Figures 1 to 4 As shown, the safety protection device for large-diameter circular pipe construction is installed and fixed on the pipe reinforcement ribs 2 on the surface of the large-diameter circular pipe 1. After installation, the entire device is located at the top of the large-diameter circular pipe 1, allowing construction personnel to hook safety belts or use it as a handrail. Specifically, it includes two opposing protective support frames connected by a protective rope 3. The protective rope 3 can be made of steel wire rope, nylon rope, etc., which is strong, not easily broken, and provides high safety. Furthermore, the distance between the two protective support frames can be adjusted according to actual operating conditions, and the protective rope 3 of appropriate length can be matched, offering good flexibility in use.

[0020] The protective support frame includes two protective support rods 4 arranged with increasing distance from top to bottom. A support rod connecting plate 5 is provided between the top ends of the two protective support rods 4. The end of the protective pull rope 3 is connected to the support rod connecting plate 5. The protective pull rope 3 and the support rod connecting plate 5 are detachably connected to facilitate replacement of the protective pull rope 3 with the required length, thereby improving the flexibility of use. The bottom end of each protective support rod 4 is fixedly connected to a support rod fixing base. The support rod fixing base and the pipe reinforcement rib 2 are detachably assembled, thereby avoiding the need for additional scaffolding, simplifying the preparation work for construction and optimizing the construction environment. Furthermore, the assembly and disassembly of the support rod fixing base and the pipe reinforcement rib 2 are simple and convenient.

[0021] Specifically, the support rod connecting plate 5 is a fan-shaped steel plate. The upper part of the support rod connecting plate 5 has a pull rope fixing hole 6 for connecting with the protective pull rope 3. A limiting block can be fixed to the end of the protective pull rope 3 to limit its connection with the pull rope fixing hole 6. Alternatively, a rope connector or similar device can be used to connect the protective pull rope 3. The limiting connection of the protective pull rope 3 is well known to those skilled in the art and will not be described in detail here. Below the pull rope fixing hole 6, the support rod connecting plate 5 has at least one row of arc-shaped support rod connecting holes 7. The two protective support rods 4 are detachably assembled with the support rod connecting plate 5 through some of the support rod connecting holes 7. In this embodiment, to improve the connection strength between the protective support rod 4 and the support rod connecting plate 5, two rows of arc-shaped support rod connecting holes 7 are provided. Each row has multiple support rod connecting holes 7, allowing the support rod connecting plate 5 to be finely adjusted according to the position of the support rod fixing base to achieve connection with the two support rod connecting plates 5.

[0022] In this embodiment, a connecting bolt 8 is detachably provided through the support rod connecting plate 5 and each of the protective support rods 4. The connecting bolt 8 is provided with a connecting nut 9 for use.
