Abstract

The utility model discloses a multi-directional climbing device for a transmission tower, which comprises a multi-directional climbing module and a base. The multi-directional climbing module includes a clamping mechanism, a climbing mechanism and a steering mechanism. Among them, the clamping mechanism and the climbing mechanism are connected through the steering mechanism. The clamping mechanism is used to clamp or loosen the tower during climbing; the climbing mechanism adopts a screw drive mechanism, and transmits the power of the rotating motor to the ball screw through a synchronous pulley assembly, so as to drive the ball screw platform to complete longitudinal movement; the steering mechanism is used to cooperate with the movement of the clamping mechanism during climbing, so that the device can smoothly turn when reaching the cross arm of the tower. The device of the utility model can climb and cross obstacles, is applicable to transmission towers of different structural types including main material angle steel and cross arms, has a strong load capacity, and can carry maintenance equipment to complete maintenance tasks.
