DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0035] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0036] like Figure 1-Figure 5As shown, it is a structural diagram of a maintenance auxiliary device for a power transmission line provided by an embodiment of the present invention, comprising a movable ring 1, an elastic detection unit, a dynamic detection unit, a stepping drive unit and a lifting unit, wherein the movable ring 1 is arranged on the outside of the transmission line 2, the elastic detection unit is slidably mounted on the movable ring 1, and the working end of the elastic detection unit abuts against the outside of the transmission line 2; the dynamic detection unit is rotatably mounted in the movable ring 1, and the dynamic detection unit rotates synchronously with the movable ring 1 to perform real-time detection of the outer surface of the transmission line 2; the stepping drive unit is mounted on the inner side of the movable ring 1, one end of the stepping drive unit abuts against the transmission line 2, and the other end of the stepping drive unit is transmission-connected to the inner gear ring 17 in the dynamic detection unit; the lifting unit is arranged at the bottom end of the movable ring 1, and casters are mounted at the bottom of the lifting unit for driving the movable ring 1 to move.

[0037] In one embodiment of the present invention, a lifting ring 22 is installed on the bottom side of the movable ring 1. The lifting ring 22 is used to pull the movable ring 1 to move along the power transmission line 2 when a pull rope or a pull rod is hung.

[0038] like Figure 1 and Figure 2 As shown, as a preferred embodiment of the present invention, the elastic detection unit includes a guide rod 3, an arc block 4, a limit block 5, an elastic support member 6 and a pressure sensor 7;

[0039] There are multiple guide rods 3, all of which are slidably mounted on the movable ring 1, and a limit block 5 is installed on the outer side of the guide rod 3;

[0040] An arc block 4 is installed on the inner side of the guide rod 3, and an elastic support member 6 is arranged between the movable ring 1 and the arc block 4 on the guide rod 3;

[0041] Therefore, a plurality of pressure sensors 7 are evenly mounted on the inner side surface of the arc block 4 .

[0042] In one example of the present invention, the number of the arc blocks 4 and the pressure sensors 7 can be adjusted as needed to cover the outer surface of the transmission line 2. When the movable ring 1 moves along the transmission line 2, the arc blocks 4 and the pressure sensors 7 move along the surface of the transmission line 2. When the diameter of the transmission line 2 changes, the arc blocks 4 are forced to push the guide rod 3 to slide along the movable ring 1, and the elastic support member 6 is elastically deformed under the force. The pressure sensor 7 transmits the force applied to it to an external controller, and the controller automatically calculates the diameter of the transmission line 2 according to the change in elasticity.

[0043] like Figure 1 , Figure 3 and Figure 4As shown, as another preferred embodiment of the present invention, the dynamic detection unit includes an inner gear ring 17, a fixed sleeve 18, a feeler rod 19, an elastic support member 20 and a detection head 21;

[0044] The inner gear ring 17 is rotatably mounted in the movable ring 1, and a fixing sleeve 18 is fixedly mounted on the inner side surface of the inner gear ring 17;

[0046] A detection head 21 is installed at the end of the feeler rod 19 .

[0047] In one example of the present invention, the inner gear ring 17 slides along the movable ring 1 when subjected to force, and the fixed sleeve 18 and the touch rod 19 move synchronously therewith, and the elastic support member 20 performs dynamic detection along the outer surface of the power transmission line 2. When the touch rod 19 is subjected to force, it slides along the fixed sleeve 18, and the elastic support member 20 built into the fixed sleeve 18 undergoes elastic deformation under the force.

[0048] like Figure 1 and Figure 5 As shown, as another preferred embodiment of the present invention, the stepping drive unit includes a bracket 1 8, a rotating shaft 1 9, a roller 10, a bracket 2 11, a rotating shaft 2 12, a pulley 13, a synchronous belt 14, a bevel gear 1 15 and a bevel gear 2 16;

[0050] A bevel gear 15 is fixedly mounted on the end of the second rotating shaft 12 . The bevel gear 15 meshes with a bevel gear 16 disposed outside the second rotating shaft 12 . The bevel gear 16 meshes with the inner gear ring 17 .

[0051] In one example of the present invention, when the roller 10 moves along the transmission line 2, the roller 10 drives the rotating shaft 9 to rotate along the bracket 8, the pulley 13 on the rotating shaft 9 rotates synchronously, and drives the rotating shaft 2 12 to rotate along the bracket 2 11 through the set synchronous belt 14, the rotating shaft 2 12 drives the bevel gear 15 and the bevel gear 2 16 to rotate, and then drives the inner gear ring 17 to rotate along the movable ring 1, thereby driving the fixed sleeve 18 to rotate synchronously.

[0052] like Figure 1As shown, as another preferred embodiment of the present invention, the lifting unit includes a bottom plate 23, a T-shaped rod 24, a multi-stage telescopic member 25 and a through hole 26;

[0053] The bottom plate 23 is arranged at the bottom end of the movable ring 1, and the T-shaped rod 24 is fixedly installed on the bottom plate 23. A support rod 27 is installed between the bottom plate 23 and the T-shaped rod 24 to improve the strength of the support;

[0054] The two ends of the T-shaped rod 24 are symmetrically mounted with multi-stage telescopic members 25 . The multi-stage telescopic members 25 and the base arranged at the bottom side of the movable ring 1 are both provided with through holes 26 and are connected via an external pin shaft.

[0055] In one example of the present invention, the multi-stage telescopic member 25 is electrically connected to an external controller for controlling the extension of the two multi-stage telescopic members 25; when in use, the multi-stage telescopic member 25 in the present application can select linear drive devices such as cylinders, hydraulic cylinders, electric cylinders and electric telescopic rods in actual applications, and adjust the extension of the multi-stage telescopic member 25 through an external controller, thereby pushing the movable ring 1 to move in the height direction.

[0056] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.

[0057] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
