Description

Technical Field

[0001] This utility model relates to the field of cable installation technology, specifically to a fixing structure for aluminum core cables. Background Technology

[0002] In power transmission and distribution systems, aluminum core cables are widely used in various industrial, civil, and infrastructure construction scenarios due to their low cost, light weight, and suitable conductivity. However, the reliability of the fixing structure of aluminum core cables directly affects the safety and stability of the overall power system during actual installation and operation. Traditional aluminum core cable fixing methods often use simple metal clamps, plastic cable ties, or bracket clamps. Over long-term use, these structures are prone to loosening and poor contact due to displacement caused by the cable's thermal expansion and contraction, external vibrations, or environmental corrosion. This can lead to localized overheating, insulation wear, and even short circuits and power outages. Furthermore, some fixing structures do not fully consider the material characteristics of aluminum core cables in their design. For example, aluminum has low hardness and is easily oxidized, which may cause compression damage to the cable body during fixing, affecting its service life and conductivity. Therefore, designing a fixing structure that ensures stable fixing of aluminum core cables while avoiding damage and adapting to complex environmental changes has become a pressing technical problem in the industry, driving continuous improvement and innovation in related fixing structures.

A fixing device is provided inside the protective shell. The fixing device includes a moving rod, with connecting blocks fixedly connected to both ends of the moving rod, a guide block fixedly connected to the other end of the connecting blocks, and a fixing plate fixedly connected to one side of the connecting blocks. The specification of prior art 1 discloses a flexible cable fixing and protection device. When in use, it can be adjusted according to the size of the cable to facilitate fixing and protecting cables of different sizes. However, in actual applications, since the cable is suspended, in windy weather, the cable is fixed and the wind blows the cable, causing it to sway. At this time, the cable will be pulled after being fixed, resulting in wear or even breakage of the cable sheath. Summary of the Invention

[0004] This utility model provides an aluminum core cable fixing structure, which aims to solve the problem that in the existing cable fixing device, when encountering strong winds, the fixed end of the cable will be pulled when the wind blows and the cable sways, resulting in damage to the cable sheath.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A fixing structure for aluminum core cables includes a fixing base, a fixing device, and a buffer device.

[0022] Please see Figures 1-3 As shown, this embodiment discloses an aluminum core cable fixing structure, including a fixing base 101, a fixing device, and a buffer device; the fixing base 101 is used to install on a plane; the fixing device is used to fix the cable; the buffer device is arranged on both sides of the fixing device, and the buffer device includes a slide rod 102, a slide cylinder 103, and a spring 104. The fixing device is provided with slide rods 102 at both ends, and slide cylinders 103 are slidably arranged on the slide rods 102. The end of the slide cylinder 103 is connected to a fixing plate 105, which is used to fix the fixing base 101. One end of the spring 104 is fixedly connected to the slide cylinder 103, and the other end is fixedly connected to the slide rod 102. The mounting base 101 is also equipped with a steering component, which is used to change the installation angle of the cable.

[0023] This utility model mainly includes a fixing base 101, a fixing device, and a buffer device. In actual use, the operator installs the fixing base 101 on the plane where the cable needs to be fixed, then passes the cable through the fixing device, which fixes the cable. Then, the cable passes through the turning assembly, which changes the installation direction of the cable. If no change is needed, the direction of the turning assembly is the same as the direction of the cable. After installation, if strong winds blow the cable, the cable will pull the fixing device to slide on the fixing base 101. At this time, the slide rod 102 slides in the slide cylinder 103. One end of the fixing device presses the spring 104 on the fixing plate 105, and the other end pulls the spring 104 on another fixing plate 105, thereby achieving overall buffering of the fixing device, effectively preventing the cable from being pulled after being shaken, and effectively protecting the cable.

[0024] In some embodiments, the fixing device includes a sliding block 106, a support groove 107, a buckle plate 108, and a pressure plate 109. The sliding block 106 is slidably mounted on the fixing base 101. Both ends of the sliding block 106 are fixedly connected to sliding rods 102. The support groove 107 is disposed on the sliding block 106. The buckle plate 108 is fastened to the support groove 107 and forms a cable routing hole 110 in the support groove 107. The pressure plate 109 is mounted on the buckle plate 108 by a screw 111. The pressure plate 109 is used to fix the cable. The screw 111 is threadedly connected to the buckle plate 108 and rotatably connected to the pressure plate 109.

[0025] In some embodiments, a rubber pad is provided on the inner surface of the pressure plate 109.

[0026] In actual use, the purpose of setting the rubber pad is to prevent the pressure plate 109 from damaging the outer surface of the cable when it squeezes the cable. The rubber pad can also increase the friction between the pressure plate 109 and the outer surface of the cable.

[0027] In some embodiments, a sliding seat 112 is provided on the fixed seat 101, a sliding block 106 is slidably mounted on the sliding seat 112, and a fixed plate 105 is fixedly mounted on the sliding seat 112.

[0029] In some embodiments, the slider 106 is slidably connected to the slider seat 112 via a sliding component.

[0030] In actual use, the use of sliding components can make the sliding between the sliding block 106 and the sliding seat 112 smoother.

[0031] In some embodiments, the sliding component includes a groove 113 disposed on the sliding seat 112 and a sliding protrusion 114 disposed at the bottom of the sliding block 106, the sliding protrusion 114 being slidably connected to the groove 113.

[0032] In actual use, the purpose of setting the groove 113 and the sliding protrusion 114 is to guide the sliding block 106 when it slides, so that the sliding block 106 is more stable when it slides.

[0033] In some embodiments, the cross-sections of the sliding protrusion 114 and the groove 113 are both T-shaped structures.

[0034] In actual use, the purpose of setting the T-shaped sliding protrusion 114 and the sliding groove 113 is to limit the radial position of the sliding block 106 during the relative sliding process between the sliding block 106 and the sliding seat 112, thereby making the sliding block 106 more stable during sliding.

[0035] In some embodiments, a support base 115 is provided on the fixed base 101, and a plurality of placement slots 116 are provided on the support base 115 for supporting the cable.

[0036] In actual use, the position and number of placement slots 116 correspond to the position and number of fixing devices. After the cable passes through the placement slots 116, it is fixed by the pressure plate 109, and finally the direction is adjusted by the steering component.

[0037] In some embodiments, the steering assembly includes a frame 117 and a rotating cylinder 118. A through groove 119 is provided on the fixed base 101. The frame 117 is installed inside the through groove 119. There are a plurality of rotating cylinders 118. The number of rotating cylinders 118 corresponds to the position of the sliding block 106 and the placement groove 116. The rotating cylinders 118 are used for damping rotation and are installed on the frame 117.

[0038] In actual use, after the cable is fixed by the pressure plate 109, the cable passes through the rotating cylinder 118. By adjusting the rotation direction of the rotating cylinder 118, the angle of rotation and bending of the cable can be adjusted.

[0039] In some embodiments, a rotating protrusion 120 is provided on the outer wall of the rotating cylinder 118, and the rotating protrusion 120 is rotatably connected to the frame 117.

[0040] In actual use, the purpose of setting the rotating protrusion 120 is to facilitate the rotating connection between the rotating cylinder 118 and the frame 117.
