[0024] The present invention will be further described below in conjunction with the drawings and embodiments.

[0025] In the description of the present invention, terms indicating orientation or positional relationship such as "center", "upper", "lower", "left", "right", "inner", "outer", etc. are based on the orientation or positional relationship shown in the drawings, rather than indicating or implying that the device referred to must have a specific orientation.

[0026] As Figures 1 to 6 shown, the present invention includes a column support 1, a rotating arm assembly 2, an articulated bracket unit 3, a hydraulic unit 4 and a pair of rotating arm telescopic cylinders 5. The column support 1 is a welded structural member, and its bottom plate 11 is fixed on the ground. The rotating arm assembly 2 includes a center seat 21, an outer tube 22, a horizontal rod 23, an articulated plate 24 and a pull rod 25. The bottom flange 211 of the center seat is vertically fixed on the top flange 121 of the column 12 made of steel pipe, and the bottom flange 122 of the column 12 is fixed on one end of the bottom plate 11.

[0027] The outer tube 22 is sleeved on the center seat 21, and a radial bearing 26 and a thrust bearing 27 are respectively supported between the upper and lower ends inside the outer tube 22 and the upper and lower ends of the center seat 21. Figure 3 The vertically arranged articulated plate 24 shown is welded and fixed on the front side of the outer tube 22 on the right side. As Figure 2 , Figure 3 and Figure 5 shown, the lower ends of a pair of vertical plates 6 are respectively symmetrically welded and fixed on both sides of the outer tube 22 through 2 right-angle rib plates 27. The right end of the horizontal rod 23 is fixed on the articulated plate 24. The left end of the pull rod 25 is hinged to the vertical plate 231 at the left end of the horizontal rod 23, and the right end of the pull rod 25 is hinged to the upper part of the articulated plate 24, so that the pull rod 25, the horizontal rod 23 and the articulated plate 24 are connected into a stable triangular structure, significantly improving the bearing capacity of the rotating arm assembly 2.

[0028] The articulated bracket unit 3 includes two groups of multi-layer inclined bracket assemblies 31 and one group of multi-layer horizontal bracket assemblies 32. The two ends of the multi-layer horizontal bracket assembly 32 are respectively hinged to the upper ends of the multi-layer inclined bracket assemblies 31 to form an "eight" shape. The multi-layer inclined bracket assemblies 31 and the multi-layer horizontal bracket assemblies 32 have the same structure. In this embodiment, both the multi-layer inclined bracket assemblies 31 and the multi-layer horizontal bracket assemblies 32 are bracket assemblies with 4 layers up and down. The side plates 311 on both sides of the multi-layer inclined bracket assemblies 31 and the multi-layer horizontal bracket assemblies 32 are arranged in parallel at intervals up and down. The vertical plates 312 are arranged at intervals outside the side plates 311. The two ends of the horizontally arranged cross bars 313 respectively pass through the side plates 311 and are hinged to the vertical plates 312, so that both sides of the multi-layer inclined bracket assemblies 31 become parallelogram mechanisms that are convenient for swinging. A plurality of wire pulleys 314 arranged side by side are respectively sleeved on the cross bars 313 at both ends of the multi-layer inclined bracket assemblies 31, and the wire pulleys 314 reduce the frictional resistance during the pulling and feeding of the cable movement. Figure 2 and Figure 3 The vertical plates 312 at the right ends of the right group of multi-layer inclined bracket assemblies 31 in [Figure number] are respectively fixed to the upper right part of the vertical plate 6, so that the articulated bracket unit 3 is fixedly connected to the rotary arm assembly 2 as a whole.

[0029] The lower side of the guiding groove 33 with a hollow rectangular cross-section is fixedly welded to the middle part of the upper side of the horizontal rod 23. The sliding rods 34 respectively pass through the long waist holes 331 on both longitudinal sides of the guiding groove 33. The two ends of one sliding rod 34 are respectively hinged to the lower ends of the first support rods 35 located outside the longitudinal sides of the guiding groove 33, and the upper ends of the first support rods 35 are respectively connected to Figure 2 and Figure 3 the corresponding cross bar 313 ends at the lowermost layer of the multi-layer inclined bracket assemblies 31 in [Figure number]. The two ends of the other sliding rod 34 are respectively hinged to the lower ends of the second support rods 36 located outside the longitudinal sides of the guiding groove 33, and the upper ends of the second support rods 36 are respectively hinged to the corresponding cross bar 313 ends at the lowermost layer of the right multi-layer inclined bracket assemblies 31. As shown in Figure 4 [Figure number], the sliding rod 34 ends at the lower ends of the first support rod 35 and the adjacent second support rod 36 are respectively connected by a connecting plate 37. The first support rod 35 and the second support rod 36 reliably support the articulated bracket unit 3 and the cable thereon.

[0030] The cylinder tail hinge ears 51 of a pair of rotary arm telescopic cylinders 5 are respectively hinged to the hinge seats 62 on the cross plate 61 welded and fixed between the vertical plates 6. The piston rod end hinge ears of the rotary arm telescopic cylinders 5 are respectively hinged to the two ends of one sliding rod 34 and the lower end of the first support rod 35. The hydraulic unit 4 is fixed on the outer side of the lower part of a vertical plate 6. As shown in Figure 4 [Figure number], when the piston rod of the rotary arm telescopic cylinder 5 extends, it drives the first support rod 35 and the second support rod 36 to move outward through the connecting plate 37, realizing the linkage expansion of the two groups of multi-layer inclined bracket assemblies 31.

[0031] As Figure 4 shown, the telescopic locking mechanism 38 includes a plurality of locking pin holes 332 and four locking pins 391 that are respectively arranged at the longitudinal two sides of the upper and lower surfaces of the guiding groove 33 at intervals. After the articulated bracket unit 3 is telescopically in place, the locking pins 391 respectively pass through the corresponding locking pin holes 332 vertically. 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, so as to lock the first support rod 35 and the second support rod 36 at the required positions respectively, prevent the articulated bracket unit 3 from suddenly collapsing, and ensure the safe use of the present invention.

[0032] As Figure 3 and Figure 6 shown, the rotation locking mechanism 7 of the rotating arm assembly is arranged between the bottom flange 211 of the central seat and the lower side of the right end of the horizontal rod 23, and includes a cross locking handle 71, a nut seat 72 and a plurality of locking holes 73 evenly distributed on the outer edge of the bottom flange 211 of the central seat. The nut seat 72 is fixed in the lower part of the U-shaped hanging plate 721, and the upper ends of the U-shaped hanging plate 721 are respectively fixed on the lower side of the right end of the horizontal rod 23. The horizontal screw 711 of the cross 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 aperture of the locking hole 73. When locking the rotation angle of the rotating arm assembly 2, rotate the cross locking handle 71 clockwise so that the locking rod 712 at the end of the cross locking handle 71 extends into the corresponding locking hole 73 when the rotating arm assembly 2 rotates in place, thereby locking the rotating arm assembly 2 at the required rotation angle.

[0033] As Figure 1 shown, a pair of rolling bearings 341 are respectively fixed on the middle part of the sliding rod 34, and the rolling bearings 341 are supported on the bottom surface of the guiding groove 33, greatly reducing the lateral movement resistance of the sliding rod 34.

[0034] As Figure 1 and Figure 2 shown, in order to facilitate the cable outlet, the single-layer inclined bracket assembly 10 is arranged outside the lower end of the vertical plate 6, and includes two inclined side plates 101, two inclined tie rods 102 and several cross bars 313. The two ends of the several cross bars 313 arranged at intervals are respectively hinged to the inclined side plates 101, and a plurality of wire pulleys 314 arranged side by side are respectively sleeved on the cross 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 sides of the middle parts of the inclined side plates 101. The rectangular frame-type wire hanging rack 8 is suspended under the middle part of the horizontal rod 23.

[0035] In addition to the above embodiments, the present invention can also have other implementation manners. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the protection scope required by the present invention.
