Abstract

The invention discloses an underwater hydraulic axis-penetrating locking device, which comprises a locking oil cylinder arranged at the lower end of a gate girder and an underwater locking console arranged on a gate embedded part. A hermetical preservative and compressive cover is installed on an upper end cover of the locking oil cylinder, and internally provided with a magnetostrictive displacement transducer of which a measuring rod is extended to a core hole of a hollow structure piston rod, and an induction ring is fixed on the ring. A locking plate is arranged on the underwater locking console, and an anti-shearing plate is arranged on one side of the locking console. The front end of the piston rod is connected with a locking shaft by an oil cylinder suspension head and a pin shaft, the pin shaft is provided with an induction measuring ring used for a limiting transducer, two limiting transducer seats are arranged on the gate web, and the locking shaft is connected with the underwater locking console in a locking way. The underwater hydraulic axis-penetrating locking device is characterized in that the locking shaft is arranged at the front end of the piston rod of the locking oil cylinder, and the penetration and escape of locking are performed by the forward and backward movement of the locking shaft, thereby realizing the locking function.

Description

technical field [0001] The invention relates to a gate locking device, in particular to an underwater hydraulic through-shaft locking device. Background technique [0002] The hydraulic locking device is a necessary condition to ensure whether the gate can meet the two-way support requirements at the bottom and realize the two-way water retaining and locking of the gate. Restricted by the layout of the gate, the locking seat of the gate can only be set on the embedded part of the gate, and it will work underwater for a long time. Manual locking does not meet the operating conditions, and the reliability of conventional automatic locking is not high, and when underwater problems occur, it is not easy to solve. Contents of the invention [0003] The object of the present invention is to provide a safe and reliable underwater hydraulic through-shaft locking device which realizes door-closing locking and maintenance locking. [0004] To achieve the above object, the present ...
