Abstract: The present invention discloses an obstacle navigation travelling device of a power line inspection robot. The present obstacle navigation travelling device of a power line inspection robot includes: a travelling device underframe; a first arm assembly mounted at one end of the travelling device underframe; a first linear driving device for driving the first arm assembly to move linearly on the one end of the travelling device underframe; a second arm assembly mounted at one end of the travelling device underframe far from the first arm assembly; a second linear driving device for driving the second arm assembly to move linearly on the one end of the travelling device underframe far from the first arm assembly; and a third arm assembly. The present invention has the beneficial effects of a large turning range and excellent balancing.

Abstract: The invention discloses a rail type anti-falling safety device including a primary bearing block, an anti-falling tongue through-groove is opened on an upper end face of the primary bearing block, an anti-falling tongue pin is provided in the through-groove, an anti-falling tongue is provided on and rotatable about the anti-falling tongue pin, the anti-falling tongue is pressed tightly against a T-shaped steel-rail surface under the action of an elastic element, the anti-falling tongue has a cam structure at the end pressed against the T-shaped steel rail surface and a hanging loop at the end far from the end pressed against the T-shaped steel rail surface. A first clamping block is provided on a lower end face of the primary bearing block. The invention allows adjustments to the groove width of the anti-falling device while the safety and reliability is ensured, thereby providing uninterrupted personal safety guarantee for the worker.
