A fixed bottom pivot of a miter gate

Abstract

The invention discloses a fixed-type bottom pivot for a miter gate. The fixed-type bottom pivot comprises a bottom pivot supporting base, a bearing pedestal gasket, a mushroom head and a bearing platform. The bearing platform is fixedly embedded in concrete. The bottom pivot supporting base is fixedly connected with a bottom beam. The bearing pedestal gasket is nested in the bottom pivot supporting base. A base of the mushroom head is placed on the bearing platform, and a bulb of the mushroom head is matched with the bearing pedestal gasket through a spherical pair. The fixed-type bottom pivot for the miter gate is characterized in that a bearing insertion block is installed at the bearing side of the bottom pivot supporting base through a detachable structure; a seal ring is installed on the journal section of the mushroom head, and a base plate is arranged between the base of the mushroom head and the bearing platform; and the bearing pedestal gasket is made of a self-lubricating material. The fixed-type bottom pivot for the miter gate has the beneficial effects of improving abrasion resistance of main operation parts, enhancing safety and stability of the bottom pivot structure and being convenient to maintain and repair.

Description

technical field [0001] The invention belongs to the technical field of water transport gate devices, and in particular relates to a fixed bottom pivot of a miter gate. Background technique [0002] With the development of society, the water transportation industry is becoming more and more prosperous. As the most widely used type of ship lock gate, miter gates are opened and closed very frequently and operate almost all year round. The problem of wear and maintenance of the bottom pivot is gradually exposed. The bottom hinge structure of the miter door is subject to heavy loads, complex forces, and poor working environment. The friction surfaces such as bearing seat liners and mushroom heads are severely worn after years of operation, and the mushroom head fixing bolts are likely to be cut off when the bottom hinge is not running smoothly. , affecting the safety and stability of the bottom pivot structure. During the inspection and maintenance of the ship lock, it is inconv...

Problems solved by technology

The bottom hinge structure of the miter door is subject to heavy loads, complex forces, and poor working environment. The friction surfaces such as bearing seat liners and mushroom heads are severely worn after years of operation, and the mushroom head fixing bolts are likely to be cut off when the bottom hinge is not running smoothly. , affecting the safety and stability of the bottom pivot structure

During the maintenance of the ship lock, it is inconvenient to replace parts such as the bottom pivot bearing block and the support block, and the maintenance period is long, which reduces the operating efficiency of the ship lock
