Technical Field

[0001] This utility model relates to the field of line maintenance and flaw detection technology, and in particular to a transmission line maintenance and flaw detection device. Background Technology

[0002] Transmission line inspection and flaw detection equipment is a specialized device used to detect and diagnose potential defects or damage in high-voltage transmission lines, aiming to prevent faults and ensure the safe operation of the power grid.

[0003] Existing line inspection and flaw detection mechanisms are placed on the inspection line, allowing the inspection and flaw detection device to move along the line and perform flaw detection on the line using a flaw detector. However, existing flaw detectors can generally only detect flaws on lines of a fixed diameter and cannot detect flaws on cables of different diameters, which limits the applicability of the inspection and flaw detection device. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that existing technologies cannot perform flaw detection on cables of different diameters, and to propose a flaw detection device for power transmission line maintenance.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A flaw detection device for power transmission line maintenance includes two parallel support plates, with a connecting plate integrally installed between the two support plates. A flaw detection machine for detecting flaws in the line is fixedly installed at the bottom of the connecting plate. Two symmetrically arranged first mounting plates are fixedly installed at the bottom of each of the two support plates, and two symmetrically arranged fixed sleeves are fixedly installed on each of the four first mounting plates. A movable plate is slidably arranged inside each of the two fixed sleeves, and a drive wheel is rotatably installed between the two movable plates.

[0006] Preferably, a second mounting plate is fixedly installed at the bottom of the connecting plate, an electric telescopic rod is fixedly installed on the second mounting plate, a connecting push plate is fixedly installed at the end of the electric telescopic rod, and two limiting holes are opened on the connecting push plate. Guide rods are slidably arranged in both limiting holes, and the ends of the two guide rods are fixedly installed on the second mounting plate.

[0007] Preferably, each of the two fixed sleeves has a sliding hole arranged opposite to the other, and a connecting push plate is slidably arranged in both sliding holes, with both ends of the connecting push plate being fixedly connected to the two moving plates respectively.

[0008] Preferably, each of the two support plates is provided with a rolling wheel at its bottom end, and a drive motor for driving the drive wheel to rotate is fixedly installed on the movable plate.

[0009] Preferably, two symmetrically arranged second mounting plates are fixedly installed at the bottom of the connecting plate, and a liquid storage tank is fixedly installed on the outer wall of each of the two second mounting plates. An output pipe connected to the liquid storage tank is fixedly installed inside each of the two second mounting plates.

[0010] Preferably, each of the two second mounting plates is fixedly equipped with a lifting ring at its bottom end, and each of the two lifting rings is equipped with a lifting hook. The bottom ends of the two lifting hooks are jointly fixedly equipped with a wire rope, and a counterweight is fixedly installed on the wire rope.

[0011] Compared with the prior art, the present invention has the following advantages: 1. This utility model uses the extension and retraction of an electric telescopic rod to move a connecting push plate and a moving plate. By adjusting the distance between the two drive wheels, the two drive wheels are brought into contact with the outer walls on both sides of the cable, thus moving the equipment. This is suitable for flaw detection of cables of different diameters.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figures 1-4 A flaw detection device for power transmission line maintenance includes two parallel support plates 1, a connecting plate 2 integrally installed between the two support plates 1, a flaw detection machine 3 for detecting flaws in the line fixedly installed at the bottom end of the connecting plate 2 by bolt assembly, two symmetrically arranged first mounting plates 5 fixedly installed at the bottom end of each of the two support plates 1 by bolt assembly, and two symmetrically arranged fixing sleeves 6 fixedly installed on each of the four first mounting plates 5 by bolt assembly, a movable plate 7 slidably arranged inside each of the two fixing sleeves 6, and a drive wheel 8 rotatably installed between the two movable plates 7.

[0017] An electric telescopic rod 13 is fixedly installed on the second mounting plate 14 by bolt assembly. A connecting push plate 11 is fixedly installed at the end of the electric telescopic rod 13 by bolt assembly. Two limiting holes are opened on the connecting push plate 11. Guide rods 12 are slidably arranged in the two limiting holes, and the ends of the two guide rods 12 are fixedly installed on the second mounting plate 14 by bolt assembly.

[0018] Both fixed sleeves 6 are provided with oppositely arranged sliding holes 10. A connecting push plate 11 is slidably arranged in both sliding holes 10, and the two ends of the connecting push plate 11 are respectively fixedly connected to the two moving plates 7 by bolt assemblies.

[0019] Both support plates 1 are equipped with rollers 4 at their bottom ends, and a drive motor 9 that drives the drive wheel 8 to rotate is fixedly installed on the movable plate 7 by bolt assembly.

[0020] Two symmetrically arranged second mounting plates 14 are fixedly installed at the bottom of the connecting plate 2 by bolt assembly. The outer walls of the two second mounting plates 14 are fixedly installed with liquid storage tanks 15 by bolt assembly. The inside of the two second mounting plates 14 are fixedly installed with output pipes 16 that are connected to the liquid storage tanks 15 by bolt assembly. The end of the output pipe 16 is integrally installed with a nozzle 17, and a delivery pump is provided on the output pipe 16.

[0021] The bottom ends of the two second mounting plates 14 are fixedly mounted with lifting rings 18 by bolt assemblies. Each of the two lifting rings 18 is equipped with a hook 19, and the bottom ends of the two hooks 19 are jointly fixedly mounted with a wire rope 20. A counterweight 21 is fixedly mounted on the wire rope 20. The counterweight 21 lowers the overall center of gravity of the equipment, making the equipment more stable when moving.

[0022] It should be noted that the bolt assembly is existing technology, specifically including bolts and bolt holes. The specific models and specifications of the flaw detector 3 and drive motor 9 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts existing technology in this field, so it will not be elaborated here.

[0023] The functional principle of this utility model can be explained through the following operation methods: In use, the device is placed on the line so that the roller 4 contacts the upper end of the cable. The connecting push plate 11 is pulled by the end of the electric telescopic rod 13 and moved towards the second mounting plate 14 in the sliding hole 10. The connecting push plate 11 pushes the moving plate 7 to move. The distance between the two drive wheels 8 is adjusted so that the two drive wheels 8 are in contact with the side walls of the line. The drive motor 9 rotates the drive wheels 8, which moves the device so that the flaw detector 3 can automatically detect the line. When a circuit fault is detected, the paint stored in the storage tank 15 is sprayed out through the nozzle 17 to mark the faulty circuit, making it easier for subsequent inspection personnel to operate. By suspending the hook 19 on the lifting ring 18, the counterweight 21 lowers the center of gravity of the equipment, making the equipment more stable when running on the line.
