Description

Technical Field

[0001] This utility model belongs to the technical field of cable laying fixing clips, and specifically relates to a cable fixing clip. Background Technology

[0002] Traditional installation methods face numerous challenges in the temporary construction cable laying process for large equipment such as thermal power plants. Due to the considerable height of the construction platforms and steel frame structures, cable laying becomes complex and carries significant risks. Traditional methods typically rely on hoisting equipment to lift the cables to the high-altitude installation location, followed by manual welding and securing by construction workers. This method not only consumes substantial manpower and resources but also presents significant safety hazards, such as the risk of falls from heights and the possibility of insecure securing due to cable weight. Furthermore, the construction process requires close coordination among multiple disciplines, including welding, electrical, and mechanical operations, increasing the complexity and time cost. In addition, traditional fixing methods struggle to guarantee long-term stability in practical use, easily leading to cable loosening due to weak welding or improper installation, thus posing safety hazards.

[0003] To overcome the above shortcomings, it is necessary to explore more efficient and safer cable fixing solutions. Although prefabricated and modular installation methods have been introduced into existing technologies, these solutions mostly rely on a large amount of manual labor, have poor installation flexibility, are difficult to adapt to the changing needs of temporary construction environments, and are costly and uneconomical in project applications.

The fastening bolt passes through the outer flat iron, the inner flat iron and the mounting structure in sequence. The fastening nut is threadedly engaged with the end of the fastening bolt.

[0006] Furthermore, the mounting structure includes: a U-shaped clamp, a fixing nut, and a tightening bolt.

[0019] To facilitate understanding of this utility model, it will be described in more detail below with reference to the accompanying drawings and specific embodiments. However, this utility model can be implemented in many different forms and is not limited to the embodiments described in this specification. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0020] The cable clamp in this application is mainly composed of flat iron, channel steel, and several bolts, nuts, and washers, assembled through fastening. All bolts and nuts are made of high-strength alloy steel, ensuring durability and reliability of the clamp in various temporary construction environments. The structure is simple in design and easy to process and assemble. This clamp simplifies the cable installation process, improves construction efficiency, and enhances the reliability and safety of cable fixation in complex construction environments. It improves the efficiency of cable fixing and removal; it is reusable, saving materials while improving on-site management of temporary construction cable laying.

[0021] Example 1: Refer to Figure 1-3 and Figure 5 A cable clamp includes: an outer flat iron 1, an inner flat iron 2, a mounting structure 3, a fastening bolt 4, and a fastening nut 5. The outer flat iron 1 and the inner flat iron 2 exist in pairs and are the main fixing components of the clamp, located on the front side of the clamp. The middle part of the outer flat iron 1 protrudes away from the inner flat iron 2, forming a groove 101 on its inner side. The two sides of the groove 101 are flat plate structures, namely a flat end A102 and a flat end B103. The inner flat iron 2 has a working plane, and the two ends of the outer flat iron 1 are installed against the working plane of the inner flat iron 2, creating a space for the cable to pass through in the middle. The mounting structure 3 serves as a support structure for the clamp, dispersing the pressure applied by the cable. One end of the mounting structure 3 is fixed to a platform support frame, and the other end is fitted with the outer flat iron 1 and the inner flat iron 2. The fastening bolt 4 passes through the outer flat iron 1, the inner flat iron 2, and the mounting structure 3 in sequence, and the fastening nut 5 is threaded into the end of the fastening bolt 4. The mounting structure 3 is fixedly installed opposite to the outer flat iron 1 and the inner flat iron 2. The mounting structure 3 includes: a U-shaped clamp 301, a fixing nut 302, and a tightening bolt 303. The fixing nut 302 is welded to the U-shaped clamp 301. The tightening bolt 303 and the fixing nut 302 are threaded together. The U-shaped clamp 301 has a through hole, and the center line of the tightening bolt 303 coincides with the center line of the through hole.

[0022] In practical applications, the installation structure 3 uses channel steel. First, the channel steel is processed and assembled into an integral support structure. Then, the inner flat iron 2 and the outer flat iron 1 are installed on the front side of the channel steel. During construction, the fixing clamp is installed on the boiler platform support structure using the U-shaped clamp 301 in the installation structure 3, and then secured by the tightening bolt 303. Specifically, in this embodiment, as... Figure 3 As shown, the first U-shaped head 304 has a horizontal opening and is positioned horizontally. The platform support 7 is located in the middle of the first U-shaped head 304 and is secured by the tightening bolt 303 screwed in and tightened. Figure 1Understood. During cable laying, the cable 6 to be fixed is placed between two flat iron pieces, and the fixing nut 5 is tightened to secure the cable together, thereby achieving rapid and stable fixing of the cable. The U-shaped structure of the groove 101 ensures that the cable is stable and does not shift. The working surface on the inner flat iron 2 ensures that the cable can be firmly positioned in the clamp, preventing the cable from sliding or loosening due to external forces or vibrations. The groove design on the outer flat iron 1 further improves the stability of the cable, allowing it to remain stable in the complex environment of the boiler.

[0023] Example 2: Unlike Example 1, in the installation structure 3, the channel steel is longer, the outer flat iron 1 and the inner flat iron 2 are located at one end, and the second U-shaped head 306 of the U-shaped clamp 301 is set at the other end, such as... Figure 4-5 As shown, the channel steel, serving as the side support structure of the fixing clamp, effectively disperses the pressure on the cable, preventing damage due to uneven local stress. Simultaneously, the channel steel provides a secure support point for the bolts, and its robust design ensures the overall durability and stability of the fixing clamp. It is suitable for various fixing platforms, particularly improving cable laying efficiency and fixing reliability in complex boiler environments. For example, platform support 28 is an I-beam, with one side extending into the second U-shaped head 306, secured by the tightening bolt 303 screwed in and tightened against that side.

[0024] In the actual installation process, the two channel steels are first welded and assembled into a whole to form the installation structure 3. Then, the inner flat iron 2 and the outer flat iron 1 are fixed to the front side of the installation structure 3 with the fastening bolts 4. The outer flat iron 1 forms a U-shaped space outward to ensure that the cable can be easily placed into this space for fixing. Then, the cable 6 to be fixed can be freely placed between the flat irons. Finally, the entire fixing clamp structure is installed on the boiler platform support structure using the tightening bolts 303 to ensure a tight connection with the platform. The entire fixing clamp is then tightened together. The pressure applied by tightening the fastening bolts 4 makes the outer flat iron 1 firmly clamp the cable 6 to be fixed, thereby achieving reliable cable fixing. The tightness of the fastening bolts 4 can be adjusted according to the diameter of the cable and specific installation requirements to ensure that the cable is neither damaged by over-clamping nor displaced by insecure fixing.

[0025] This invention proposes a cable clamp specifically designed for temporary construction power supply. This device simplifies installation, reduces time spent working at heights, and improves construction efficiency, while ensuring the stability of the cable fixation, thereby reducing the risk of cable loosening due to environmental factors. This clamp can be pre-installed at a designated location before cable laying; once the cable is in place, installation is completed simply by rotating the bolts, significantly reducing construction difficulty and safety risks. This design not only improves construction safety and efficiency but also significantly reduces the input of manpower and materials, providing an efficient and reliable solution for temporary cable laying.

[0026] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
