Embodiment Construction

[0018] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0019] Such as figure 1 , figure 2 As shown, the hydraulic bow door device of this embodiment includes a bow door that is movably installed on the deck 2 through a hinge shaft 1. The bow door includes a door frame 3 and a door leaf 4 that are sealed and installed together. A hydraulic drive cylinder is installed on the front side of the door frame 3 5. The cylinder body of the hydraulically driven cylinder 5 is hinged to the door frame 3, and the end of the piston rod is hinged to the hinge shaft 1 through the first connecting rod assembly. After the piston rod of the hydraulically driven cylinder 5 is pushed out, the bow door is turned over and placed horizontally Status; a foldable guardrail assembly is installed on the front side of the bow door. Such as figure 2 As shown, the first connecting rod assembly includes a first connecting...

Abstract

The invention relates to a hydraulic bow door device, comprising a bow door moveably installed on a deck through a hinged shaft; the bow door comprises a door frame and a hinge which are installed together in a sealing manner; the front face side of the door frame is equipped with a hydraulic driving cylinder, and a cylinder body of the hydraulic driving cylinder is hinged with the door frame; the end part of a piston rod thereof is hinged with the hinged shaft through a first link rod component; after pushing out the piston rod of the hydraulic driving cylinder, the bow door is overturned to be a horizontal placing state; the front face side of the bow door is equipped with a foldable guardrail component. According to the invention, the guardrail component is combined with the bow door; when the bow door is opened, the guardrail can be unfolded, so as to guarantee the protecting safety of a channel formed after connecting the bow door with a wharf; the hydraulic bow door device is reasonable in structural design; the opening operations of the guardrail and the bow door are simple; when the hydraulic driving cylinder drives the bow door, the route is short, and the supporting stability is good.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a bow door device. Background technique [0002] The bow door is the door located at the front of the ship. After opening, the bow springboard can be connected to the dock, which is convenient for vehicles to pass up and down. The bow door currently used only plays the role of connecting the ship and the wharf after being opened, and has a single function, and the existing hydraulic bow door has a large stroke of the hydraulic cylinder and poor opening stability. Contents of the invention [0003] Aiming at the above-mentioned problems existing in the existing bow door, the applicant conducts research and improvement, and provides a hydraulic bow door device. The present invention adopts the following scheme: [0004] A hydraulic bow door device, including a bow door that is movably installed on the deck through a hinge shaft, the bow door includes a door frame and a door leaf t...
