[0033] In one embodiment, Figure 1-Figure 10 As shown, the bracket adopts a frame-integrated iron structure, which is mainly composed of functional components (rollers), supporting components (supports) and structural components (beams and columns).

[0034] The functional components (rollers) include straight rollers 5 and transverse rollers 6, wherein the straight rollers 5 are mainly used to constrain the turning radius of cable laying, while the transverse rollers 6 mainly provide cable support. The two types of rollers have the same structure, but slightly different lengths. Both are welded from hot-dip galvanized steel pipes, discs, rings, etc. with different outer diameters. The roller is the only movable component of the cable bracket 2, and its two ends are movably installed in the reserved circular holes of the support component (support).

[0035] The support component (support) is used to install the functional component (roller) on the structural component (beam column), including two categories: flat steel support 7 and angle steel support, among which the angle steel support is further divided into three types: first angle steel support 8, second angle steel support 9, and third angle steel support 10. The flat steel support 7 is made of hot-dip galvanized flat steel with a specification of -63×6×140, and its characteristic is that it needs to be embedded in the reserved square hole 13 of the channel steel column 4, so it needs to be processed into an irregular shape according to the inner contour line of the channel steel, and the flat steel support 7 and the channel steel column 4 are welded and fixed along the contact part of the inner contour line. The first angle steel support 8 is made of hot-dip galvanized angle steel with a specification of ∠63×63×6×140. Its characteristics are that one side of the angle steel needs to be embedded in the reserved square hole 13 of the channel steel column 4 and needs to be processed into an irregular shape according to the inner contour line of the channel steel; while the other side needs to be installed close to the leg end of the channel steel column 4, so the first angle steel support 8 is welded and fixed to the channel steel column 4 along the inner contour line and the leg end contact part. The second angle steel support 9 is made of two hot-dip galvanized angle steels with a specification of ∠63×63×6×140 welded in reverse to form a "Z" shape. In addition, in order to strengthen the supporting effect, hot-dip galvanized flat steel with a specification of -63×6×140 is used as a reinforcing rib, which is welded with the two angle steels to form an integral structure. The second angle steel support 9 is welded and fixed to the channel steel column 4 along the leg end contact part. The third angle steel support 10 is made of a hot-dip galvanized angle steel with a specification of ∠63×63×6×140. The third angle steel support 10 is welded and fixed to the lower channel steel beam 3 along the contact part of the leg end.

[0036] The structural components (beams and columns) are composed of channel steel columns 4 and channel steel beams 3 to form an overall frame structure, all of which are made of #14a hot-dip galvanized channel steel (specifications are [140×58×6). The characteristic of the channel steel column 4 is that a number of 103×6 square holes 13 are reserved on the web, which are the embedding holes of the flat steel support 7 and the first angle steel support 8; in addition, the legs are cut off at the end to be embedded in the square holes 13 reserved for the channel steel beam 3. The characteristic of the channel steel beam 3 is that a number of 103×6 square holes 13 are reserved on the web, which are the embedding holes at the end of the channel steel column 4, and a number of φ18 round holes 14 are reserved for connection with the expansion bolts 12 on the ground of the working pit. The contact part between the channel steel column 4 and the channel steel beam 3 is fixed by welding.

[0037] The above embodiment discloses a corner well cable support for ensuring the cable laying radius. When in use, several groups of straight rollers 5 are installed on the channel steel straight column 4 through the flat steel support 7 and the first angle steel support 8, and several groups of transverse rolling shafts 6 are installed through the second angle steel support 9 and the third angle steel support 10. Then, the cable support 2 is fixed to the inner wall and the bottom ground of the corner well through several groups of expansion bolts 12, so that the corner laying of several groups of main bodies 1 can be realized, which is relatively convenient.

[0038] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
