Clamping jaw type locking device capable of turning for bulkhead gate

The invention discloses a clamping jaw type locking device capable of turning for a bulkhead gate. The locking device comprises locking platforms symmetrically arranged on the two sides of the bulkhead gate, wherein locking beams are arranged on the upper portions of the locking platforms, locking support arms are arranged on one sides, close to the bulkhead gate, of the locking support arms, and the locking support arms are connected with the locking beams through locking shafts and self-lubricating shaft sleeves; and hanging bodies are arranged on the two sides of the bulkhead gate, and the hanging bodies are clamped with the locking supporting arms. The locking device is simple in structure, reliable in technology, economical and practical; and according to the locking device, the locking support arms can turn around the shafts so that automatic locking or unlocking can be realized when the gate is opened and closed; and manual operation is not needed in the using process, so that the problems that the bul
