Description

Technical Field

[0001] The utility model relates to the technical field of power transmission line detection, in particular to a power transmission line detection device. Background Art

[0002] With the gradual increase in the demand for electricity consumption in society, the number of power transmission lines in my country is increasing every year. On the vast power transmission lines, the detection of power transmission lines has become an important task for the power department. Many power transmission lines are built in very high places, and generally professionals climb up the power transmission lines for crawling inspection. The long-term crawling inspection is very physically demanding for personnel, and physical strength is easily consumed, so a power transmission line detection device is needed.

[0003] If the existing power transmission line detection device adopts closed running wheels, it is difficult for the actual operator to hang the running wheels of the detection device on the power transmission line. For example, the existing patent announcement number CN218726760U discloses "a power transmission line detection device", and the detection device body is provided with a support rod and a running wheel. The support rod is in a U-shaped structure, and the transmission line is closed together with the running wheel. However, this closed structure can only detect this section of the line, and its applicability is greatly reduced. If the running wheel and the support rod form a semi-enclosed C-shaped structure, although it is convenient to hang the device and the running wheel on the power transmission line, it is easy to fall off, and is affected by the ups and downs of the power transmission line and rain and snow. When the above-mentioned device is moving, only the upper running wheel is driven. When the friction is insufficient, it is easy to slip, making the detection device unable to move.

The semi-annular component 10 is also a semi-annular structure. The pressing wheel 7 can be raised and lowered by using the linear motor 5. When the pressing wheel 7 descends, the bracket 2, the walking wheel 3 and the pressing wheel 7 form a C-shaped structure. At this time, the device is in an open state.

Since the second half ring 102 is provided with teeth 107, and the second half ring 102 can slide on the first half ring 101 by using the slider 104 and the annular groove 103, the first half ring 101 and the second half ring 102 can encircle the transmission line, so that the transmission line can be fully detected.

[0023] The two sides of the U-shaped frame 6 are vertically provided with sliding grooves 12, and a sliding member 13 is slidably connected in the sliding grooves 12. The axle of the pressing wheel 7 is rotatably mounted on the sliding member 13, and a spring 14 is fixedly mounted on the bottom of the sliding member 13.
