Problems solved by technology

Beneficial effects of this utility model: Comparing the laying effect of cables at the cross intersection and T-shaped opening of the cable trench, it is found that after installing the opposite-sex FRP cable bracket, the cables are arranged neatly, the binding is firm, and the cables have no sagging phenomenon. Compared with the cable arrangement in front of the support, the quality of the cable arrangement has been significantly improved; however, this utility model cannot adjust the height of the utility model and the horizontal support according to the needs, which is inconvenient to use, complicated in structure, and cannot meet the requirements of humid environments , short service life

Embodiment 1

[0031] Such as figure 1 As shown, an adjustable cable special-shaped support includes a base 1, wherein the base 1 is provided with mounting holes 2 for installing the present invention on the bottom of the intersection of the cable trench, which can be fixed by bolts or welded. A support rod 3 is set in the center of the base 1, wherein the base and the support rod can be welded or plugged in. The present invention is welding, wherein the support rod 3 is a hollow tube with a square cross section, and the support rod 3 is inserted inside There is a movable rod 4, and a plurality of threaded holes 5 are sequentially arranged at the corresponding positions of the movable rod 4 and the support rod 3 from top to bottom, wherein the longitudinal distance between the threaded holes 5 can be set to 150-180 mm as required. In this embodiment It is set to 150mm; because there will be water in the bottom of the cable trench, the distance between the threaded hole 5 at the bottom of the...

Embodiment 2

[0038] Embodiment 2 is basically the same structure as Embodiment 1, the difference is: as image 3 As shown, bolts are used between the support bar 3 and the movable bar 4, and the outer end of the cross bar 6 is hollow, and the inner thread is connected to the extension bar 9. When there are many cables and the width of the present invention is not enough, it can be extended by increasing Bar 9 increases the use width of the present invention, which is convenient and practical.

[0039] And the base 1, the support rod 3, the movable rod 4 and the horizontal support are all sprayed with waterproof and corrosion-resistant paint, wherein the waterproof and corrosion-resistant paint is made of the following raw materials in parts by weight: 32 parts of silicon acrylic emulsion, 11 parts of acrylic emulsion, silica sol 4 parts, 3.5 parts of titanium dioxide, 7 parts of ethylene glycol, 1.2 parts of sodium lauryl sulfate, 0.3 parts of dispersant, 5 parts of nano silicon carbide, 1...

Embodiment 3

[0042] Embodiment 3 is basically the same structure as Embodiment 2, the difference is: as Figure 4 As shown, the transverse support includes two transverse bars at the same level. In this embodiment, the two transverse bars 6 are horizontally arranged, and the threaded connection between the transverse bars 6 and the threaded holes 5. At this time, the direction of the cable is as follows: Figure 4 As shown, therefore the structure of the present invention can be adjusted according to the situation of the cable trench, which is very convenient and practical.

[0043] And the base 1, the support rod 3, the movable rod 4 and the horizontal support are all sprayed with waterproof and corrosion-resistant paint, wherein the waterproof and corrosion-resistant paint is made of the following raw materials in parts by weight: 34 parts of silicon acrylic emulsion, 10 parts of acrylic emulsion, silica sol 5 parts, 4 parts of titanium dioxide, 6 parts of ethylene glycol, 1.5 parts of s...

Abstract

The invention discloses a cable support, and belongs to the technical field of transmission line construction. The cable support comprises a base, installation holes are formed in the base, a supporting rod is fixed in the center of the base, the supporting rod is a hollow pipe, and a movable rod is in inserting connection with the supporting rod; and a plurality of threaded holes are formed sequentially in the corresponding positions of the movable rod and the supporting rod from top to bottom, a plurality of groups of transverse supports are arranged sequentially on the movable rod and the supporting rod from top to bottom, each group of transverse supports comprises two transverse rods which are located on the same horizontal plane, the transverse rods are in threaded connection with the threaded holes, and reinforcing rods are correspondingly arranged on the periphery of the supporting rod. The cable support is arranged on a crossed position of cable trenches, the cable support is adopted to arrange cables so that the cables can be more orderly arranged, the cables can be prevented from falling off, and meanwhile, the cable support can be used for the cable trenches with various heights and widths; and waterproof corrosion-resistant coatings are sprayed on the base, the supporting rod, the movable rod and the transverse supports of the cable support so that the cable support can be acid and alkali resistant, water resistant, salt resistant and long in service life.

Description

technical field [0001] The invention relates to the technical field of transmission line construction, in particular to a cable support. Background technique [0002] In recent years, with the rapid development of the national economy, the number and scale of substations are constantly expanding. With more and more cables in the stations, more and more underground cables are used. The installation of underground cables is usually realized by cable trenches. When laying cables in the trench, the cables cannot be laid directly in the cable trench. The cables need to be laid on the bracket for overhead protection to avoid external damage. However, the cables may fall off due to improper layout at the intersection of the cable trench. Potential safety hazards are caused, and the operation and maintenance costs are high and difficult after the cable falls off. [0003] Chinese Patent Publication No. CN 203574339 U discloses a cable bracket for a cable trench, including a cross b...
