Walking clamping combined structure for inspection robot

The invention relates to an inspection robot mechanism and particularly relates to a walking clamping combined structure for an inspection robot. The structure comprises a walking wheel drive motor, a support, a walking wheel, a lifting mechanism, a clamping drive motor, a linkage mechanism and a clamping wheel. The support is mounted on an arm of the inspection robot, the walking wheel drive motor is arranged on the support, and the walking wheel is disposed above an overhead ground wire and is connected with an output shaft of the walking wheel drive motor and driven by the walking wheel drive motor to walk on the overhead ground wire. The lifting mechanism is mounted on the support and is connected with the clamping drive motor and driven by the clamping drive motor to rise and descend. The clamping wheel is arranged below the overhead ground wire and is connected with the lifting mechanism through the linkage mechanism and driven by the lifting mechanism to clamp or loosen the overhead ground wire. According to the mechanism, the clamping wheel performs clamping or loosening through the linkage mechanism, required moving space is small, the length of the inspection robot arm can be reduced, and reduction of the size and the weight of the inspection robot is facilitated.
