Embodiment Construction

[0023] The present invention will be further described below in combination with specific embodiments and accompanying drawings.

[0024] A marine hydraulic weathertight hinged door without threshold, such as Figure 1-6 As shown, including door leaf 1 and matching door frame 2,

[0025] The door leaf 1 and the door frame 2 are rotatably connected by a lifting hinge device 11 located on one side of the door frame 2,

[0026] A rubber sealing strip 3 is installed around the door leaf 1, and the left side, the upper side and the right side of the rubber sealing strip are respectively in contact with the pressing plate 4 arranged on the door frame 2, and the bottom edge of the rubber sealing strip is in contact with the pressing plate on the hull deck. Tight plate 4 contacts;

[0027] The lifting cylinder 6 arranged on one side of the door frame 2 is connected with the lifting hinge device 11 through a pin shaft; the lifting cylinder 6 lifts and lowers the door leaf through the...

Abstract

The invention relates to a threshold-free hydraulic weather-tight hinged door for a ship. The threshold-free hydraulic weather-tight hinged door comprises a door frame, a door leaf, a lifting hinge device, a sealing rubber strip, an oil cylinder and the like. In order to meet the requirements of large equipment, cargoes, vehicles and in-out cabins on a ship, a hinged door frame is required to be threshold-free, and a conventional hydraulic weather-tight hinged door cannot meet the requirements. The door frame is of a threshold-free structure, and a door body sealing strip needs to meet the sealing requirement on a door frame sealing face and a bottom deck sealing face. The hinge is a lifting hinge. Before the door leaf is opened or closed, the door leaf is lifted to a certain height by the lifting oil cylinder through the lifting hinge, so that collision or friction caused by contact between a sealing strip at the bottom of the door leaf and a ship body deck (including a guide rail and other structures arranged on the ship body deck) in the opening and closing process is avoided; after the door leaf is opened, the hydraulic control one-way valve arranged on the door opening oil cylinder can fix the door leaf, and the door body is prevented from swinging due to shaking of the ship body. The hinge door can meet the weather tight requirement, and the flushing test pressure reaches 0.2 MPa.

Description

technical field [0001] The invention belongs to the technical field of ship stern bulkheads, in particular to a marine hydraulic weathertight hinged door without threshold. Background technique [0002] With the development of the ship industry, customers have higher and higher requirements for ship outfitting equipment. In the original technology, the hydraulic weathertight hinged door is mainly composed of door frame, door leaf, switch cylinder, hinge device, locking device and other connections. This kind of hydraulic weathertight hinged door has a high threshold and cannot meet the needs of entering and exiting large equipment, goods and vehicles. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a hydraulic weather-tight hinged door without threshold for ships, which facilitates the entry and exit of large equipment, goods, vehicles and personnel. It adopts electro-hydraulic control and...
