Description

Technical Field

[0001] This utility model relates to the field of industrial and power facility technology, specifically a cable fixing device on a steel frame. Background Technology

[0002] Steel frames are widely used as primary load-bearing structures in building construction, bridge construction, and the construction of large industrial facilities. During the construction phase, cables are typically laid on the steel frames to meet the needs of on-site lighting, power supply for electrical equipment, and other applications. To ensure the orderly laying and safe management of cables, they are usually secured to the steel frames.

[0003] Chinese utility model patent CN212626914U discloses a temporary cable fixing device for construction sites, including a mounting plate and a cable fastener. The mounting plate has mounting holes symmetrically distributed along its left and right edges. The cable fastener includes a fixed fastener and a movable fastener. The fixed fasteners are symmetrically distributed on both sides of the movable fastener, and a connecting plate is fixedly connected between them. The connecting plate is fixedly connected to the mounting plate. A sliding plate is fixedly connected to the bottom of the movable fastener, located in the middle of the connecting plate and slidably connected to it. A rectangular groove is provided at the connection between the movable fastener and the connecting plate, and a locking threaded rod is provided on the surface of the sliding plate. This device secures the cable using the fixed fastener, movable fastener, and locking threaded rod.

[0004] The existing technologies, including the aforementioned patents, have the following problems: In practical use, the fixing direction of cables varies, and they may be installed perpendicular to the ground or parallel to the ground. If the fixing of cables is considered and the fixing device is designed only from the perspective of a single direction, it will limit the applicable scenarios of the device. Cables usually need to be fixed to load-bearing structures such as steel frames, and the fixing point of the base is often not a flat and wide ground or wall surface. Flat bases may face problems such as inconvenient installation and insufficient device stability. Utility Model Content

[0005] The main objective of this novel experimental device is to provide a cable fixing device on a steel frame to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A cable fixing device on a steel frame includes: a base, which is detachably fixed to the steel frame; a connecting arm, which is fixedly connected to one end of the base away from the steel frame; and a fixing assembly, which includes a support portion for limiting and supporting the cable, with connecting portions connected to both ends of the support portion, and the connecting portions being detachably fixed to the outer surface of the connecting arm by a fixing member.

[0008] Furthermore, a protective section is provided between the support portion and the connecting arm to protect the cable sheath. The cable sheath, which contacts the connecting arm and support portion, is more prone to wear; providing a protective section at this location extends the cable's service life and reduces safety hazards.

[0009] Furthermore, one side of the base is provided with a U-shaped groove for securing the steel frame, and the sidewall of the U-shaped groove is connected to the steel frame via a fastener. The U-shaped groove facilitates quick insertion of the base into the steel frame, reducing installation complexity.

[0010] Furthermore, the second fixing component includes a threaded rod fixed to the connecting arm, the end of which passes through the connecting part and is tightened with a nut. This facilitates assembly and disassembly, increasing the flexibility and reusability of the device.

[0011] Furthermore, the support portion is semi-circular in shape. The semi-circular shape in the middle is designed to mimic the outline of the cable. The semi-circular shape and symmetrical structural design can increase the contact area between the fixing component and the cable and balance the circumferential pressure distribution, effectively reducing local stress concentration.

[0012] Furthermore, the connecting arm has an L-shaped cross-section, and the base is provided with a U-shaped groove. Since the connecting arm is fixedly connected to the base, the right-angle design of the L-shaped connecting arm can disperse the stress of the cable's weight on the connection point. The combination of the two reduces the installation complexity while ensuring structural strength, achieving a balance between lightweight design and high load-bearing capacity.

[0013] As can be seen from the above solutions, this utility model has the following beneficial effects:

[0014] This invention detachably fixes the base to the steel frame, and the connecting part is detachably fixed to the outer surface of the connecting arm via a second fastener, facilitating assembly and disassembly and adapting to flexible and complex practical environments. A U-shaped groove is provided on the base; the U-shaped opening better fits the steel frame structure, offering greater stability and practicality compared to a flat base. The connecting arm has an L-shaped cross-section with two outer surfaces, allowing the fixing component to be positioned on one of the outer surfaces depending on the cable's fixing direction. The supporting part of the fixing component is semi-circular, increasing the contact area between the fixing component and the cable and evenly distributing circumferential pressure, effectively reducing localized stress concentration.

[0020] like Figures 1-3 As shown, a cable fixing device on a steel frame includes: a base 1, which is detachably fixed to a steel frame 5; a connecting arm 2, which is fixedly connected to the end of the base 1 away from the steel frame 5; and a fixing assembly 3, which includes a support part 32 for limiting and supporting the cable, with connecting parts 31 connected to both ends of the support part 32, and the connecting parts 31 being detachably fixed to the outer surface of the connecting arm 2 by a fixing member 33.

[0021] Preferably, the fixing component 3 adopts a symmetrical arc-shaped support plate, and the connection method between the connecting arm 2 and the base 1 is welding.

[0022] like Figures 1-3 As shown, a protective part 4 is provided between the support part 32 and the connecting arm 2 to protect the cable sheath. Preferably, the protective part 4 is a wear-resistant rubber pad, evenly wrapped around the cable 6. The wear resistance increases the service life of the protective part 4. Rubber, as an insulating material, is wear-resistant, tough, cold-resistant (low-temperature resistant), water-resistant, aging-resistant, acid and alkali-resistant, weather-resistant, has a long service life, and is UV-resistant, thus increasing the stability of the device. Especially in dynamic environments, such as when the cable frequently moves or vibrates, even wrapping can prevent excessive wear at any point, extending the cable's lifespan. Simultaneously, the protective part 4 has a certain sealing performance, which can isolate liquids, gases, dust, etc., improving the stability of the device.

[0023] like Figure 3 As shown, one side of the base 1 is provided with a U-shaped groove 11 for fitting the steel frame 5. The side wall of the U-shaped groove 11 is connected to the steel frame 5 by a fastener 12. Specifically, a U-shaped groove 11 is provided at one end of the base 1 to facilitate the quick insertion of the base into the steel frame 5. Preferably, the fastener 12 is a pair of screws, and mounting holes are pre-drilled on the side wall of the U-shaped groove 11.

[0024] like Figures 2-3 As shown, the fixing component 33 includes a threaded rod 331 fixed to the connecting arm 2. The end of the threaded rod 331 passes through the connecting part 31 and is tightened with a nut 332. The connecting arm 2 has an L-shaped cross-section. The connecting arm 2 has two outer surfaces, and the fixing component 3 can be set on one of the outer surfaces according to the fixing direction of the cable. The outer surface welded to the base 1 and the outer surface connected to the connecting part 31 can be the same outer surface or different outer surfaces.

[0025] Preferably, a threaded hole is provided on the connecting arm 2, and the threaded rod 331 is fixed by screwing it into the hole, with the hexagonal head of the threaded rod 331 facing away from the connecting part 31. The outer side 21 of the connecting arm 2 is welded to the base 1, and the end of the threaded rod 331 passes through the connecting part 31 and is tightened with a nut 332 to fix the connecting part 31 to the outer side 21.

[0026] like Figure 3 As shown, the support part 32 is semi-circular and matches the outer periphery of the cable.

[0027] Before use, place the base 1 on the edge of the target steel frame, ensuring the U-shaped groove 11 on the base 1 fits the edge structure of the steel frame 5. The base 1 is detachably installed onto the steel frame by passing the fastener 12 through the pre-drilled mounting holes on the base. The outer side 21 of the connecting arm 2 is welded to the end of the base 1 away from the U-shaped groove 11. The connecting arm 2 has an L-shaped cross-section and, after installation, forms a support structure for connecting the fixing component 3. A protective part 4 is provided between the connecting arm 2 and the support part 32 of the subsequently installed fixing component 3, wrapping around the cable 6 to prevent damage from pressure or scratches. The support part 32 covers the outside of the cable 6 wrapped with the wear-resistant rubber pad 4, forming a clamping structure together with the outer side 21 of the connecting arm 2. A threaded hole is made on the connecting arm 2, and the threaded rod 331 is fixed by screwing it into this hole. The hexagonal head of the threaded rod 331 faces away from the connecting part 31. The end of the threaded rod 331 passes through the connecting part 31 and is tightened with a nut 332 to ensure the stability of the cable 6. When it is necessary to readjust the cable layout or dismantle the device, simply remove the nut 332, take off the fixing component 3, and the cable 6 can be taken out; if the entire device needs to be dismantled, further remove the fixing component 12, and the base 1 can be removed from the steel frame 5 for convenient reuse.
