The application discloses a cable trench cover plate intelligent hydraulic lifting system and a running method thereof, and belongs to the field of cable trench cover plate lifting equipment. The system is an independent mobile external device, is not integrated in the cover plate body, and comprises a walking and supporting chassis, a four-column synchronous lifting system, a self-adaptive grabbing hook system, an environment sensing module and a control system cluster. The system realizes millimeter-level centering through two-stage positioning, realizes cover plate horizontal lifting by relying on master-slave displacement following load distribution dynamic compensation algorithm, and realizes non-destructive locking of the cover plate without a preset lifting hole through the self-adaptive grabbing hook. The three safety interlocking mechanisms form a software and hardware double insurance. The application realizes single-person operation of the cover plate opening and closing, solves the problems of low efficiency and high risk of manual carrying, and solves the problems of general equipment adaptation to narrow space and cover plate without lifting points, improves operation safety and operation and maintenance efficiency, and can realize equipment health assessment and remote monitoring, and adapts to high-frequency operation and maintenance requirements of the power and municipal industries.
