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

Embodiment Construction

[0030] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0031] Such as 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] Such as 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 t...

Abstract

The invention discloses a carrying and obstacle crossing mechanism for electromagnetic detection of a power transmission line. The carrying and obstacle crossing mechanism comprises a driving motor mounted on a fixed plate, wherein a swing arm which is capable of circumferentially swinging by taking an output shaft of the motor as a circle center when the motor rotates is mounted on the output shaft of the driving motor and the swing arm is connected with a seat plate positioned under the swing arm through springs and a connection rod; the springs are perpendicularly mounted over the axis of the power transmission line under a free state; an elliptical limiting through hole is formed in the middle part of the seat plate; the connection rod penetrates through the elliptical limiting through hole; a self-locking screw cap of which the size is greater than the length of a short axis of the elliptical limiting through hole is arranged at the lower end of the connection rod in a sleeving manner; the lower part of the seat plate is connected with pulleys which are capable of being clamped on the power transmission line and an electromagnetic detection device which is used for performing electromagnetic detection on the power transmission line. The carrying and obstacle crossing mechanism is used for carrying the electromagnetic detection device and has the functions of preventing shaking, stabilization, obstacle crossing and the like.

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...
