Electric vehicle for routing inspection of power transmission lines

An electric vehicle for routing inspection of power transmission lines, used for routing inspection along multiple divided cables of high-voltage power transmission lines comprising:

• a body;
• a running mechanism mounted to the body, comprising a front wheel and a rear wheel connected by a cross beam and rolling on the cable, the front and rear wheels each having an annular groove on its circumferential rim for receiving the cable therein;
• an obstacle sensor directing forward with respect to the front wheel;
• and a cam rotatably mounted to the cross beam, the cam rotating to roll onto the cable after an obstacle is detected on the cable within an effective range in front of the front wheel by the obstacle sensor, to support a front portion of the cross beam upwards such that the front wheel is raised to a position above the cable, and the cam continuing rolling on the cable after the front wheel passes the obstacle such that the front portion of the cross beam falls back downwards and the front wheel then falls back onto the cable, wherein two of the running mechanisms are running on two parallel cables, respectively;
• a hanging seat rotatably hanging to the body, below the running mechanisms;
• and
• a control device at least partially disposed in the hanging seat and comprising a braking device, the braking device having a braking block able to detachably press against a lower surface of the cable and/or the front wheel and/or the rear wheel;
• wherein each of the two running mechanisms is mounted to the body by a respective hanging arm;
• and
• each hanging arm has a lower end mounted to the body and an upper end above the cable for mounting the running mechanism, at least one of the hanging arms is movable, with its lower end rotatably mounted to the body such that the two hanging arms can rotate with respect to each other to be in a close state or an open state, wherein in the close state, the front and rear wheels of the two running mechanisms are mounted and positioned on the cables;
• and
• wherein at least one of the two hanging arms has a telescopic portion in the direction of the length such that the upper end of the hanging arm has an adjustable elevation.
