Technical Field

[0001] The utility model relates to the technical field of cable supports, in particular to a supporting device for power cables. Background Art

[0002] Cable is a wire made of one or more mutually insulated conductors and an outer insulating protective layer. It is laid underground, in the air, etc. Cables are generally composed of three parts: conductor, insulating layer, and protective layer. There are usually two types of power cables and control cables. Power cables are mainly used for the transmission and distribution of electric energy; control cables are mainly used for measurement, protection, control and other lines. Cables have the characteristics of internal power supply and external insulation.

[0003] After searching, the existing Chinese patent announcement number is: CN 211296127 U, which provides a power cable insulator that prevents cables from falling off. The patent winds the wires and cables between the top plate and the cable placement chamber, and then slides the wound wires and cables into the interior of the cable placement chamber. The two ends of the incoming and outgoing wires of the wires and cables are respectively embedded in the interior of the cable placement groove. The setting of the cable placement chamber and the cable placement groove avoids the problem of the cable falling off the insulator.

[0004] Although the above patent can prevent the cable from falling off the insulator, the above-mentioned power cable insulator for preventing the cable from falling off still has the following problems: the distance between the two insulators cannot be adjusted well, and thus cannot be adjusted well according to the position of the cable, which easily causes the cable to not remain horizontal.

[0005] In view of the above problems, a supporting device for a power cable is proposed. Utility Model Content

[0011] As a further description of the above technical solution: two limiting slideways are provided inside the first fixed block, limiting sliders are slidably connected inside the two limiting slideways, and the two limiting sliders are fixedly connected to the surface of the movable support block.

[0012] By adopting the above technical solution, through the provision of the limiting slider and the limiting slideway, it is convenient to limit the movable support block, thereby preventing the movable support block from sliding out from the interior of the fixed block.

[0013] As a further description of the above technical solution: a second fixed block is fixedly installed on the surface of the movable support block, a sliding rod is movably connected inside the second fixed block, a fixed plate is fixedly installed on the upper end of the sliding rod, a nut hole is opened on the surface of the fixed plate, and the nut hole matches the nut.

[0014] By adopting the above technical solution, the nut hole is no longer sleeved on the nut, and thus the nut is no longer restricted, thereby preventing the nut from rotating.

[0017] As a further description of the above technical solution: two protrusions are fixedly installed on the surface of the sliding rod, and two grooves are formed on the second fixed block. The two protrusions are respectively slidably connected with the inside of the two grooves.

[0018] By adopting the above technical solution, through the arrangement of two protrusions and two grooves, the fixing plate can be rotated 180 degrees in the opposite direction, so that the disassembly of the top plate is no longer affected, thereby facilitating the installation of the cables.

[0019] Compared with the prior art, the beneficial effects of the utility model are:

[0031] When fixing the cable, rotate the nut 11 to move the nut 11 upward, so that the nut 11 is no longer located on the surface of the first threaded rod 5, and then remove the top plate 8 from the cable placement chamber 6, and then pass the cable from the inside of the cable placement groove 7, and then pass it out from the inside of another cable placement groove 7, and then rotate the nut 11 to make the top plate 8 complete the fixation of the cable, so as to facilitate the fixation of the cable, and then by rotating the second threaded rod 20, the movable support block 4 slides inside the first fixed block 3, so as to facilitate the adjustment of the distance between the two cable placement chambers 6, and then facilitate the adjustment of the distance between the two cables according to the needs of use, so as to prevent the cables from being interfered with, improve the convenience of device installation, and provide convenience for the staff.

[0032] A supporting side rod 2 is fixedly installed on the cable bracket 1, and two limiting slides 18 are opened inside the first fixed block 3. The insides of the two limiting slides 18 are slidably connected with limiting sliders 19, and the two limiting sliders 19 are fixedly connected to the surface of the movable support block 4.

[0033] A second fixed block 14 is fixedly installed on the surface of the mobile support block 4, and a sliding rod 12 is movably connected inside the second fixed block 14. A fixed plate 9 is fixedly installed on the upper end of the sliding rod 12. A nut hole 10 is opened on the surface of the fixed plate 9, and the nut hole 10 is consistent with the nut 11. A circular plate 13 is fixedly installed on the bottom of the sliding rod 12, and a spring 16 is movably sleeved on the surface of the sliding rod 12. The upper end of the spring 16 is fixedly connected to the second fixed block 14, and the lower end of the spring 16 contacts the top of the circular plate 13.

[0034] When the nut 11 is disassembled, the fixing plate 9 is pulled upwards to make the sliding rod 12 slide inside the second fixing block 14, thereby squeezing the spring 16, and then the fixing plate 9 is rotated so that the nut hole 10 is no longer sleeved on the nut 11, and the nut 11 is no longer restricted, thereby preventing the nut 11 from rotating on its own and preventing the nut 11 from loosening, thereby improving the safety of the device, and avoiding the top plate 8 and the first threaded rod 5 from being separated to the greatest extent, thereby improving the fixing effect of the cable.

[0039] When the sliding rod 12 slides inside the second fixed block 14, the two protrusions 15 will slide inside the two grooves 17.
