Abstract

The utility model discloses a lock herringbone lock gate door top automatic rising guardrail device. The device comprises an upstream side automatic lifting guardrail, a gate vertical fixing beam and a gate fixing oblique beam. When the gate is closed, the automatic lifting guardrail rises, so that a protection effect is achieved, personnel on the top of the gate door are prevented from falling carelessly, and personal safety is protected; when the gate needs to be opened, the automatic lifting guardrail falls down, the gate normally enters the door storehouse is not influenced, and the gate is completely opened, so that the ship smoothly passes through the ship lock. In addition, the automatic lifting guardrail also needs to be pulled up manually under the condition of sudden circuit failure, so that the normal navigation of the ship lock is not influenced.

Description

Automatic lifting guardrail device for door top of ship lock herringbone lock door

Technical Field

The utility model relates to a lock herringbone lock gate door top automatic rising guardrail technical field specifically is a lock herringbone lock gate door top automatic rising guardrail device.

Background

Ship lock refers to a kind of "navigable building". In natural rivers, because of the regulation of flow, canalization navigation and the restriction of topographic conditions and water surface gradient on the canal, a step-shaped vertical section is required to form a concentrated water surface drop. The vessel must be moved directly through the drop by means of a special navigable building. Modern navigable buildings are most commonly used in ship locks. The lock chamber is a chamber-shaped chamber for berthing a ship (or a fleet), and the water level in the lock chamber is adjusted by filling water or draining water in the lock chamber, so that the ship vertically ascends and descends between upstream and downstream water levels, and the water level difference of a concentrated channel is passed. When boats and ships went upstream by the low reaches, indoor water level falls to flushing with the low reaches water level, then opens the gate of low reaches lock head, and the lock room is gone into to the ship, closes the gate, and the watering is waited that the water level rises to flush the back with the upper reaches water level, opens the lock head gate of upper reaches, and the ship can go out the floodgate and navigate to the upper reaches through upper reaches approach channel.

The gate top of the miter gate of the Huaihe ship lock is designed and built in the early stage, and considering that the gate enters the door storehouse when the lock is closed, the fixed guardrail cannot be installed on the upstream side, and the fixed guardrail can be installed on the downstream side. This would result in one side having the guard rail and one side having no guard rail when the gate is closed. When a person walks on the walking stick, the person can fall into the water by accident (such as night, raining, icing, playing and alarming) to cause personal injury.
