[0026] like Figures 1-6 As shown, this utility model includes a column support 1, a rotating arm assembly 2, a hinge bracket unit 3, a hydraulic unit 4, and a pair of rotating arm telescopic cylinders 5. The column support 1 is a welded structural component, and its base plate 11 is fixed to the ground. The rotating arm assembly 2 includes a center seat 21, an outer tube 22, a horizontal bar 23, a hinge plate 24, and a tie rod 25. The bottom flange 211 of the center seat is vertically fixed to the top flange 121 of the steel pipe column 12, and the bottom flange 122 of the column 12 is fixed to one end of the base plate 11.
[0027] The outer tube 22 is fitted onto the center seat 21, and the radial bearing 26 and the thrust bearing 27 are respectively supported between the upper and lower ends of the inner side of the outer tube 22 and the upper and lower ends of the center seat 21. Figure 3 The vertically arranged hinge plate 24 shown is welded and fixed to the front side of the outer tube 22 on its right side. (See figure) Figure 2 , Figure 3 and Figure 5 As shown, the lower ends of a pair of vertical plates 6 are symmetrically welded and fixed to both sides of the outer tube 22 by two right-angle rib plates 27. The right end of the horizontal rod 23 is fixed to the hinge plate 24. The left end of the tie rod 25 is hinged to the vertical plate 231 at the left end of the horizontal rod 23, and the right end of the tie rod 25 is hinged to the upper part of the hinge plate 24. Thus, the tie rod 25, the horizontal rod 23 and the hinge plate 24 are connected to form a stable triangular structure, which significantly improves the load-bearing capacity of the rotating arm assembly 2.
[0028] The hinged bracket unit 3 includes two sets of multi-layer inclined bracket assemblies 31 and one set of multi-layer horizontal bracket assemblies 32. The two ends of the multi-layer horizontal bracket assembly 32 are hinged to the upper ends of the multi-layer inclined bracket assembly 31 in a figure-eight shape. The multi-layer inclined bracket assembly 31 and the multi-layer horizontal bracket assembly 32 have the same structure; in this embodiment, both the multi-layer inclined bracket assembly 31 and the multi-layer horizontal bracket assembly 32 are bracket assemblies with a total of four layers. The side plates 311 on both sides of the multi-layer inclined bracket assembly 31 and the multi-layer horizontal bracket assembly 32 are arranged parallel to each other vertically. Vertical plates 312 are spaced apart on the outside of the side plates 311. The two ends of the spaced horizontal bars 313 extend through the side plates 311 and are hinged to the vertical plates 312, making both sides of the multi-layer inclined bracket assembly 31 a parallelogram mechanism that is easy to swing. Multiple parallel-arranged wire pulleys 314 are respectively fitted onto the horizontal bars 313 at both ends of the multi-layer inclined bracket assembly 31. The wire pulleys 314 reduce the frictional resistance during cable movement and cable feeding. Figure 2 and Figure 3 The vertical plate 312 at the right end of a multi-layer inclined bracket assembly 31 on the right side is fixed to the upper right side of the upright plate 6, so that the hinge bracket unit 3 and the rotating arm assembly 2 are fixedly connected as one unit.
[0029] The hollow rectangular cross-section guide groove 33 is welded and fixed to the upper middle part of the horizontal rod 23. The sliding rod 34 passes through the elongated slots 331 on both sides of the longitudinal direction of the guide groove 33. The two ends of the sliding rod 34 are respectively hinged to the lower end of the first support rod 35 located on the outer longitudinal direction of the guide groove 33. The upper end of the first support rod 35 is respectively connected to... Figure 2 and Figure 3 The bottom end of the crossbar 313 of the multi-layer inclined bracket assembly 31 is hinged. The two ends of another sliding rod 34 are respectively hinged to the lower ends of the second support rod 36 located longitudinally outside the guide groove 33, and the upper ends of the second support rod 36 are respectively hinged to the bottom end of the crossbar 313 of the bottom layer of the multi-layer inclined bracket assembly 31 on the right side. (Example) Figure 4 As shown, the sliding rod 34 at the lower end of the first support rod 35 is connected to the sliding rod 34 at the lower end of the adjacent second support rod 36 via a connecting plate 37. The first support rod 35 and the second support rod 36 reliably support the hinged bracket unit 3 and the cables thereon.

The piston rod end hinges of the rotary arm telescopic cylinders 5 are respectively hinged to both ends of a sliding rod 34 and the lower end of the first support rod 35. The hydraulic unit 4 is fixed to the lower outer side of a vertical plate 6. Figure 4 As shown, when the piston rod of the rotating arm telescopic cylinder 5 extends outward, it drives the first support rod 35 and the second support rod 36 to move outward through the connecting plate 37, thereby realizing the linkage deployment of the two sets of multi-layer inclined bracket assemblies 31.
[0031] like Figure 4 As shown, the telescopic locking mechanism 38 includes multiple locking pin holes 332 and four locking pins 391, which are respectively spaced apart on the upper and lower longitudinal sides of the guide groove 33. When the hinge bracket unit 3 is telescopically extended to the position, the locking pins 391 pass vertically through the corresponding locking pin holes 332. The locking pin holes 332 are respectively located outside the sliding rod 34 hinged to the lower end of the first support rod 35 and outside the sliding rod 34 hinged to the lower end of the second support rod 36, thereby locking the first support rod 35 and the second support rod 36 in the required positions, preventing the hinge bracket unit 3 from suddenly collapsing and ensuring the safety of the present invention.
[0032] like Figure 3 and Figure 6 As shown, the rotating arm assembly rotation locking mechanism 7 is located between the bottom flange 211 of the center seat and the lower right side of the horizontal rod 23. It includes a cross-shaped locking handle 71, a nut seat 72, and multiple locking holes 73 evenly distributed on the outer edge of the bottom flange 211 of the center seat. The nut seat 72 is fixed to the lower part of the U-shaped hanging plate 721, and the upper end of the U-shaped hanging plate 721 is fixed to the lower right side of the horizontal rod 23. The horizontal screw 711 of the cross-shaped locking handle 71 is screwed into the nut seat 72, and the outer diameter of the locking rod 712 at the end of the horizontal screw 711 matches the diameter of the locking hole 73. When locking the rotation angle of the rotating arm assembly 2, the cross-shaped locking handle 71 is rotated clockwise, causing the locking rod 712 at the end of the cross-shaped locking handle 71 to extend into the corresponding locking hole 73 when the rotating arm assembly 2 is rotated to its desired position, thereby locking the rotating arm assembly 2 at the required rotation angle.
[0033] like Figure 1 As shown, a pair of rolling bearings 341 are fixed on the middle part of the sliding rod 34. The rolling bearings 341 are supported on the bottom surface of the guide groove 33, which greatly reduces the lateral resistance of the sliding rod 34.
[0034] like Figure 1 and Figure 2 As shown, to facilitate cable exit, a single-layer inclined bracket assembly 10 is installed on the lower outer side of the vertical plate 6, including two inclined side plates 101, two inclined tie rods 102, and several horizontal bars 313. The two ends of the spaced-apart horizontal bars 313 are respectively hinged to the inclined side plates 101. Multiple parallel wire pulleys 314 are respectively fitted onto the horizontal bars 313. The upper ends of the inclined tie rods 102 are respectively hinged to one side of the upper part of the vertical plate 6, and the lower ends of the inclined tie rods 102 are respectively hinged to the outer side of the middle part of the inclined side plates 101. A rectangular frame-type cable hanger 8 is suspended on the lower side of the middle part of the horizontal bar 23.
