Hinge type light hydraulic watertight door under roll-on-roll-off ship

Abstract

The invention relates to a hinge type light hydraulic watertight door under a roll-on-roll-off ship, which comprises a door body, a hinge, a support, a sealing rubber strip, a hydraulic oil cylinder, a locking device and an oil cylinder support, wherein the watertight door is matched with a vehicle slope, the end part of the slope is arranged near a watertight bulkhead, the hinge is arranged below the door, and the door body is placed on the slope when the door is opened and forms an integer with the slope so as to be convenient to a vehicle to pass through; and the door is opened and closed by using the hydraulic oil cylinder, the periphery of the door is provided with the sealing rubber strip, the locking device is utilized for locking the door after the door is closed, so that the watertightness of the door is ensured. The distance between the watertight bulkhead and the end part of the slop is selected according to the gradient of the slope and a hinge installing space, part of the slope close to the watertight bulkhead locally concaves, the concave depth is equal to the thickness of the door body, the concave length is equal to the length of the door body, and when the watertight door is opened, the door body can be flatly placed on the slope and forms an integer with the slope so as to be convenient to the vehicle to pass through.

Description

technical field [0001] The invention relates to a lower-hinged light hydraulic watertight door for a roll-on ship. Through the watertight door, vehicles can pass through conveniently, and the watertightness of the bulkhead can be guaranteed to meet the requirements. Background technique [0002] There is a watertight door on the watertight bulkhead of the vehicle compartment of the ro-ro ship. When the door is opened, the vehicle can pass through it. When the door is closed, the bulkhead is a watertight bulkhead, which meets the requirements of the "Code" for the airtightness of the cabin. There are three types of watertight doors commonly used at present: upper hinge type, side hinge type and side sliding type. Both the upper hinge type and the side hinge type must be equipped with a threshold, which hinders the passage of vehicles, and these two types of watertight doors occupy a large space; 1. There must be a guide rail on the bottom, which is equivalent to the threshol...

Problems solved by technology

There are three types of watertight doors commonly used at present: upper hinge type, side hinge type and side sliding type. Both the upper hinge type and the side hinge type must be equipped with a threshold, which hinders the passage of vehicles, and these two types of watertight doors occupy a large space; , There must be a guide rail below, the lower guide rail is equivalent to the threshold, and in order to meet the requirements of watertightness, the size of the door hole is limited, sometimes it cannot meet the needs of vehicles passing through
