Plane center horizontal door structure

Abstract

The invention discloses a plane center horizontal door structure. The plane center horizontal door structure comprises a gate body; the gate body at least includes a branch hinge side arranged on the side of a lock chamber side pier, and a movable side with the support hinge side as rotating axis; the movable side is stopped on the lock chamber side pier through a hinge base structure; a fixed wheel branch hinge is arranged at the bottom and / or the top of the branch hinge side, and includes a main shaft connected to the gate body; a main roller is rolled on one part, projected on the gate body, of the main shaft; the hinge base structure is arranged on the outer peripheral surface of the main roller for locking and releasing the main roller; and the hinge base structure is connected with a first lock chamber side pier for forming a chute. The gate body is reliable and stable in opening / closing; the silting of a lock head section is eliminated; the maintenance is convenient; and in the water leveling period, after the hinge base structure is released, the gate body is totally lifted out of a lock chamber through the chute for land maintenance without influencing normal ship navigation, so that such requirements as navigation, flood control and water retaining are satisfied.
