Problems solved by technology
It's just that there are very few types of mechanisms for carrying electromagnetic detection devices, and because traditional detection devices are all integral structures, it is difficult to automatically pass through obstacles when they encounter obstacles.
In addition, in actual use, since the transmission line is not completely horizontal, but has a certain inclination angle, or there is a high degree of undulation on the surface of the intersection of the crimping sleeve and the transmission line at the crimping joint, this will cause the detection device to be relatively Tilt and Shake of Transmission Line Axis Center

Embodiment Construction
[0030] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0031] like figure 1 As shown, the present invention includes an opening and closing drive motor platform, a swing arm 3, a connecting rod 5, a first compression spring 4, a second compression spring 7, a seat plate 6, a first pulley 8, a second pulley 12, an electromagnetic detection device.
[0032] like figure 2 As shown, the opening and closing drive motor platform includes a fixed plate 1, a drive motor 2 and bearings. The fixed plate 1 is used as the base of the whole mechanism to fix the mechanism to the transmission line inspection robot 13, and the drive motor 2 is fixed to the fixed plate 1 as the joint of the mechanism through the connecting piece and the bearing, and the swing arm 3 is fixed through the connecting piece It is fixedly connected to the output shaft of the drive motor 1 along the radial direction of the shaft. When the dri...

The invention discloses a carrying and obstacle-surpassing mechanism for electromagnetic detection of transmission lines, which includes a driving motor installed on a fixed plate, and a pendulum that swings in a circle with the output shaft as the center of a circle when the motor rotates is installed on the output shaft of the driving motor. The swing arm is connected to the seat plate directly below the swing arm through a spring and a connecting rod. The spring is vertically installed directly above the axis of the transmission line in a free state. There is a limiting elliptical through hole in the middle of the seat plate. The connecting rod passes through the limiting elliptical through hole, and the lower end of the connecting rod is fitted with a self-locking nut whose size is larger than the minor axis length of the limiting elliptical through hole; the lower part of the seat plate is connected with a pulley that can be stuck on the power line, and Electromagnetic detection device for electromagnetic detection of transmission lines. The mechanism is used to carry electromagnetic detection devices, and has the functions of anti-shake, stability, and obstacle surmounting.
Description
technical field [0001] The invention relates to an on-line patrol inspection mechanism for transmission lines, in particular to a carrying and obstacle-surmounting mechanism for electromagnetic detection of transmission lines, and belongs to the technical field of transmission line robots. Background technique [0002] The integrity of the high-voltage transmission line structure is very important for the safe operation of the transmission system. Since the transmission line works outdoors, it has been subjected to huge alternating tension and bending stress caused by vibration for a long time, which will inevitably cause cracks and broken strands in the conductors and ground wires of the transmission line. In addition, the surface of the transmission line will be damaged due to rapid changes in temperature and lightning strikes. If it is laid on the seashore or in an industrial area, it is easy to cause corrosion damage due to salt spray and acid rain. In addition, the tra...
