The invention discloses a dynamic descending speed limiting device for a high altitude cable climbing robot. The dynamic descending speed limiting device for the high altitude cable climbing robot comprises a stator, a rotor and a mandrel, wherein a plurality of inclined sliding grooves are uniformly formed in a circumferential direction of the rotor; an inertial block matched with the inclined surface of the inclined sliding groove is placed in each inclined sliding groove; each inertial block is laminated with a sliding disk under an effect of a pressure spring; conical valve cores are arranged on the sliding disks; hydraulic chambers, internal side blind holes and external side blind holes, which are communicated with each other, are formed in the stator; impellers are arranged in the hydraulic chambers; the internal side blind holes comprise conical holes in which steel balls connected with the springs are arranged; and conical valve holes matched with the conical valve cores are arranged in the external side blind holes. After the structure is adopted, the dynamic descending speed limiting device for the high altitude cable climbing robot, disclosed by the invention, is advantaged in that the structure of the dynamic descending speed limiting device is simple and compact, the braking force of the dynamic descending speed limiting device can dynamically self-adaptively change with the change of descending speed; the lower limit speed of the robot is controllable, the braking resistance comes from damping force generated when a fluid flows through a damping hole, pure mechanical friction type thermal decay problem does not exist, the dynamic descending speed limiting device can perform long-time and long-distance braking, and the promotion value of the dynamic descending speed limiting device is high.
