DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] The embodiment of the present application provides a power corridor cable support, which solves the main common bottleneck problems faced in the manufacturing and assembly process of the high-voltage cable support structure of the cable tunnel, such as molding quality, performance testing, eddy current loss, installation difficulties and poor flexibility in cable laying in the later stage, and realizes that the cable installation base surface 305 is fixed at different positions on the arc-shaped cable support 2, which is convenient for fixing the cable at a suitable position on the arc-shaped cable support 2, and is convenient for installing and fixing the cable, without the need for on-site secondary processing, greatly improving the installation efficiency, reducing the labor intensity, and adjusting the angle between the cable arm support 301 and the cable installation base surface 305, which is suitable for different installation environments, solves the problems of installation difficulties and poor flexibility in cable laying in the later stage, and the installation angle between the cable arm support 301 and the base 302 is adjustable;

[0034] In order to make full use of the cross-sectional space of the circular tunnel, the arc-shaped cable bracket 2 adopts the same arc surface structure design as the pipe gallery tunnel, is closely combined with the inner wall of the tunnel, and is integrally manufactured through an extrusion one-time molding process to obtain a mesh structure with a pulley edge. Compared with traditional metal brackets, it has higher strength and good bending and torsion resistance.

[0035] The arc cable bracket 2 is more corrosion-resistant than the traditional steel structure bracket and does not require secondary anti-corrosion treatment. By non-magnetizing the aluminum alloy material, the arc cable bracket 2 has no hysteresis and eddy current loss, and has better environmental protection and energy-saving effects in subsequent long-term use.

[0036] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0037] An embodiment of the present invention discloses a cable support for a power pipeline gallery.

[0038] According to the attached Figure 1-8 As shown, it includes a fixing frame 1, an arc-shaped cable support 2, a plurality of supporting units 3 and a connecting unit 4. The arc-shaped cable support 2 is located inside the fixing frame 1, the supporting unit 3 is arranged on the inner wall of the arc-shaped cable support 2, and the connecting unit 4 is arranged between the corresponding plurality of supporting units 3.

[0039] The support unit 3 includes a base 302 slidably connected to the arc-shaped cable bracket 2, a cable arm bracket 301 is rotatably connected to the outer peripheral wall of the base 302, and a cable installation base surface 305 is fixedly connected to the cable arm bracket 301. When it is necessary to adjust the positions of the cable arm bracket 301 and the cable installation base surface 305, the base 302 is slid along the inner wall of the sliding groove 202 to adjust the position of the base 302 on the arc-shaped cable bracket 2. At this time, the cable installation base surface 305 is fixed to different positions on the arc-shaped cable bracket 2, which is convenient for fixing the cable at a suitable position on the arc-shaped cable bracket 2, and is convenient for installing and fixing the cable without on-site secondary processing, which greatly improves the installation efficiency and reduces the labor intensity;

[0040] The connecting unit 4 includes a connecting frame 401 fixedly connected to the base 302 and the cable arm bracket 301, a sliding seat 402 is slidably connected to the inner wall of the connecting frame 401, a rotating rod 403 is rotatably connected to the inner wall of the sliding seat 402, and two sides of the rotating rod 403 are rotatably connected to the corresponding base 302 respectively;

[0041] As the rotating rod 403 rotates, the base 302 is pushed to slide on the inner wall of the sliding groove 202, changing the position of the cable arm bracket 301 on the arc-shaped cable bracket 2. The two rotating rods 403 have the same rotation angle, ensuring that the bases 302 on both sides move the same distance and the spacing between the multiple bases 302 is the same, which is beneficial to limit the distance between the cables and protect the cables.

[0042] An adjustment unit 5 is provided between the cable arm bracket 301 and the base 302. The adjustment unit 5 includes a threaded rod 502 and a connecting rod 501 located between the cable arm bracket 301 and the base 302. The threaded rod 502 is slidably connected to the inner wall of the connecting rod 501.

[0043] When the angle of the cable installation base 305 needs to be adjusted, the nut seat 503 is rotated so that the nut seat 503 drives the threaded rod 502 to slide along the inner wall of the connecting rod 501. The connecting rod 501 and the threaded rod 502 are rotated under the sliding of the threaded rod 502, and the cable arm bracket 301 is pushed to drive the rotating frame 303 to rotate along the connecting seat 304, so as to adjust the angle between the cable arm bracket 301 and the cable installation base 305. This is suitable for different installation environments and solves the problems of difficult installation and poor flexibility in cable laying in the later stage. The installation angle between the cable arm bracket 301 and the base 302 is adjustable.

[0044] A plurality of support frames 101 are fixedly connected between the fixing frame 1 and the arc-shaped cable support 2. Since the tunnel structure is generally a cement prefabricated part type, in order to ensure that the tunnel structure strength is not affected after the cable support is installed, the cable support fixed to the tunnel is strictly prohibited from using expansion bolts or other methods that damage the tunnel strength. In order to make full use of the cross-sectional space of the circular tunnel, the arc-shaped cable support 2 adopts the same arc surface structure design as the pipe gallery tunnel, is tightly combined with the inner wall of the tunnel, and is integrally manufactured through an extrusion one-time molding process to obtain a mesh structure with a wheel edge. Compared with traditional metal supports, it has higher strength and good bending and torsion resistance.

[0045] When the tunnel is under construction, the grounding ring can be pre-buried in the tunnel. After the tunnel is completed, the processed arc-shaped columns can be welded to the pre-buried ring according to the serpentine laying pitch.

[0046] Due to the arc-shaped structure, the bracket is close to the inner wall of the circular tunnel, and the structural form is more reasonable. The weight of the cable and the thermomechanical force generated by thermal expansion and contraction are dispersed to each clamp and released, completing the performance control design of the aluminum alloy bracket.

[0047] The arc cable bracket 2 is more corrosion-resistant than the traditional steel structure bracket and does not require secondary anti-corrosion treatment. By non-magnetizing the aluminum alloy material, the arc cable bracket 2 has no hysteresis and eddy current loss, and has better environmental protection and energy-saving effects in subsequent long-term use.

[0048] This project uses high-strength aluminum alloy adjustable cable tunnel self-supporting combined bracket. The cable clamp is made of high-strength aluminum alloy and fixed to the cable arm bracket 301 with stainless steel bolts. The bolt strength should meet the requirements of line short-circuit electrodynamic conditions. The contact surface between the clamp and the cable should be smooth and free of burrs, and the clamp outlet should be curved to avoid increased local stress on the cable.

[0049] A limit frame 201 is fixedly connected to the inner wall of the arc-shaped cable bracket 2, and a sliding groove 202 is provided between the arc-shaped cable bracket 2 and the limit frame 201, and the sliding groove 202 fits with the base 302, and the base 302 is fixedly connected to the inner wall of the arc-shaped cable bracket 2 by bolts. When it is necessary to adjust the position of the cable arm bracket 301 and the cable installation base 305, the base 302 is slid along the inner wall of the sliding groove 202 to adjust the position of the base 302 on the arc-shaped cable bracket 2. At this time, the cable installation base 305 is fixed to different positions on the arc-shaped cable bracket 2 by bolts, so that the cable can be fixed at a suitable position on the arc-shaped cable bracket 2 conveniently, and the cable can be installed and fixed conveniently without the need for on-site secondary processing, which greatly improves the installation efficiency and reduces the labor intensity.

[0050] A connecting seat 304 is fixedly connected to the outer wall of the base 302, and a fixing seat 306 is fixedly connected to the bottom end face of the connecting seat 304. Rotating frames 303 are rotatably connected to both sides of the connecting seat 304. The side of the rotating frame 303 away from the connecting seat 304 is fixedly connected to the outer wall of the cable arm bracket 301. The rotating frame 303 is driven by the cable arm bracket 301 to rotate along the connecting seat 304, and the angle of the cable installation base surface 305 is adjusted. It is suitable for different installation environments and solves the problems of difficult installation and poor flexibility in subsequent cable laying.

[0051] The bottom end surface of the cable arm bracket 301 is fixedly connected to a second rotating seat 506, the outer wall of the fixed seat 306 is fixedly connected to a first rotating seat 505, the inner wall of the first rotating seat 505 is rotatably connected to a first rotating block 507, and the inner wall of the second rotating seat 506 is rotatably connected to a second rotating block 508.

[0052] The second rotating block 508 is fixedly connected to the threaded rod 502, the first rotating block 507 is fixedly connected to the connecting rod 501, the inner wall of the connecting rod 501 is slidably connected to the limit seat 504, the limit seat 504 is fixedly connected to the end of the threaded rod 502, the outer peripheral wall of the threaded rod 502 is threadedly connected with a nut seat 503, and the nut seat 503 is rotatably connected to the connecting rod 501. When it is necessary to adjust the angle of the cable installation base 305, the nut seat 503 is rotated at this time, so that the nut seat 503 drives the threaded rod 502 to slide along the inner wall of the connecting rod 501, and the threaded rod 502 is adjusted. Under sliding, the connecting rod 501 and the threaded rod 502 rotate, and at this time, the second rotating block 508 and the first rotating block 507 rotate in the second rotating seat 506 and the first rotating seat 505. Under the rotation of the connecting rod 501 and the threaded rod 502, the cable arm bracket 301 is pushed to drive the rotating frame 303 to rotate along the connecting seat 304, and the angle between the cable arm bracket 301 and the cable installation base 305 is adjusted. When the cable installation base 305 is adjusted to a suitable angle, it is suitable for different installation environments, which solves the problems of difficult installation and poor flexibility in subsequent cable laying.

[0053] A sliding groove 405 is provided on the inner wall of the connecting frame 401 , and the sliding seat 402 is slidably connected to the inner wall of the sliding groove 405 .

[0054] A screw rod 404 is threadedly connected to the inner wall of the sliding seat 402, and the screw rod 404 is rotatably connected to the inner wall of the connecting frame 401. One end of the screw rod 404 outside the connecting frame 401 is fixedly connected to a handle 406. When the position of the base 302 needs to be adjusted, the bolts on the upper and lower corresponding bases 302 are removed to make the base 302 and the arc-shaped cable bracket 2 not fixed. At this time, the screw rod 404 is driven to rotate by rotating the handle 406;

[0055] Under the rotation of the screw rod 404, the sliding seat 402 rotates along the outer peripheral wall of the screw rod 404, so that the sliding seat 402 slides on the connecting frame 401. At this time, the sliding seat 402 rotates to drive the rotating rod 403 to rotate. Under the rotation of the rotating rod 403, the base 302 is pushed to slide on the inner wall of the sliding groove 202, and the position of the cable arm bracket 301 on the arc cable bracket 2 is changed. The rotation angles of the two rotating rods 403 are the same, which ensures that the bases 302 on both sides move the same distance and the spacing between the multiple bases 302 is the same, which is conducive to limiting the distance between the cables and protecting the cables.

[0056] It is easy to install and fix the cables without the need for on-site secondary processing, which greatly improves installation efficiency and reduces labor intensity;

[0057] The cable arm bracket 301 drives the rotating frame 303 to rotate along the connecting seat 304, and adjusts the angle of the cable installation base surface 305, which is suitable for different installation environments and solves the problems of difficult installation and poor flexibility of subsequent cable laying.
