Description

Lift-up stern door structure

This creation is about a flip-up stern door structure, especially a stern door structure used on large ships. The primary application of this creation is to use a flip-up design to meet the needs of ship operation.

According to the law, the watertight door installed on the stern outer plate for loading and unloading goods and for personnel to enter and exit is called the "stern door". The stern passage system of some ships is composed of a stern door and a gangway, which is used for large air cushion boats to enter and exit the dock, and is the key to the entire passage system. Among them, the stern gangway is fixed to the dock deck through hinges, and the stern door is hung on the stern sealing plate through hinges. The stern gangway is turned upward to close, and the stern door is turned downward to close. The two are locked together by hydraulic pressure and pressed against the rubber of the door frame, thereby closing the stern part of the ship, effectively separating the outer side of the hull and the dock, and playing the role of a watertight bulkhead.

However, the stern doors of general ships open downwards, and after opening, they provide a bridge function for loading and unloading cargo and for personnel to enter and exit. However, this type of stern door is not used on ships. If the ship is throwing reconnaissance objects into the water, the downward-flipping stern door with a bridge will make it impossible to throw.

Today, the creators, in the spirit of continuous improvement and based on their rich experience in design, development and actual manufacturing in the relevant industry for many years, have specially provided a lift-up stern door structure in the hope of achieving the purpose of better practical value.

The main purpose of this invention is to provide a flip-up stern door structure, especially a stern door structure used on a large ship, which is designed to meet the purpose of ship operation through a flip-up design.

The main purpose and function of this invention's lift-up stern door structure are achieved by the following specific technical means:

It is mainly provided with an exit at the rear end of the ship, and a stern gate is installed at the exit, wherein a base is erected around the inner side of the exit, and power cylinders are respectively provided on both sides of the base, and the output shaft end of the power cylinder corresponds to the stern gate hinge assembly, and a pulley is provided on the stern gate, and the pulley is embedded in the guide rail on the base; thereby, by driving the power cylinder to operate, the pulley of the stern gate can slide and move in the guide rail, so that the stern gate can be opened or tightly closed relative to the stern exit, so as to achieve the safety effect and advantage of stable control and reliable opening and closing.

The invention provides a preferred embodiment of the lift-up stern gate structure, wherein a first positioning seat and a second positioning seat are further provided at the upper and lower positions of the pulleys on both sides of the stern gate, and a latch seat corresponding to the first positioning seat and the second positioning seat is provided on the base, and a latch rod is provided in the latch seat, and the latch rod is correspondingly latched in the first positioning seat to keep the stern gate tightly closed to close the outlet, or the latch rod is correspondingly latched in the second positioning seat to keep the stern gate lifted up to open the outlet.

In a preferred embodiment of the lift-up stern door structure of the invention, at least one sealing buckle rod is provided on the two side door edges of the stern door, and an inclined guide seat is provided at the base corresponding to the sealing buckle rod.

In order to make the technical content, purpose and effect of this creation more complete and clear, we explain it in detail below. Please also refer to the disclosed diagrams and figure numbers:

First, please refer to the first to third figures, which are the three-dimensional appearance and side section schematic diagrams of the lifting stern door structure of this invention. It is mainly provided with an exit (11) at the rear end of the ship (1), and a stern door (2) is installed at the exit (11), wherein:

A hinge part (21) is provided on both sides above the stern gate (2), and a base (12) is set up around the inner side of the outlet (11). A power cylinder (3) is respectively assembled on both sides of the base (12). The output shaft end of the power cylinder (3) corresponds to the hinge part (21) of the stern gate (2). A guide rail (13) is respectively provided on both sides above the base (12), and a pulley (22) is provided on the inner side of the stern gate (2) corresponding to the guide rail (13). The pulley (22) slides and displaces in the guide rail (13) to form the stern gate (2) to be lifted up or tightly closed.

Please refer to the first to fourth figures. The stern gate structure of this invention is mainly used on large ships. The stern gate (2) of this type of ship weighs several tons. Therefore, the operation must be stable and the switch must be sure to ensure its safety during the opening and closing process. When it is actually used, the power cylinder (3) is controlled to operate, so that the output shaft end extends and links the stern gate (2) to lift, so that the pulley (22) of the stern gate (2) slides and moves in the guide rail (13). Furthermore, the guide rail (13) is an arc guide rail (13), so that the pulley (22) drives the stern gate (2) along the path of the arc guide rail (13). The stern gate (2) is opened [as shown in the first and fourth figures]; on the contrary, when the output shaft end is retracted and linked to the stern gate (2) to rotate downward and close, the pulley (22) of the stern gate (2) slides and moves in the guide rail (13), allowing the pulley (22) to drive the stern gate (2) to close downward and tightly along the path of the arc guide rail (13) [as shown in the second and third figures].

As the stern gate (2) weighs several tons, the opening and closing process needs to be ensured and maintained in a safe state. Please refer to the fifth and sixth figures. A first positioning seat (23) and a second positioning seat (24) are provided at the upper and lower positions of the pulley (22) on both sides of the stern gate (2), and a latch seat (14) corresponding to the first positioning seat (23) and the second positioning seat (24) is provided on the base (12). A latch rod (141) is provided in the latch seat (14). The latch rod (141) is latched in the first positioning seat (23) to keep the stern gate (2) tightly closed to close the outlet (11), or the latch rod (141) is latched in the second positioning seat (24) to keep the stern gate (2) open to open the outlet (11).

As shown in FIG. 7, at least one sealing buckle rod (25) is provided on the two side door edges of the stern door (2), and an inclined guide seat (15) is provided on the base (12) corresponding to the sealing buckle rod (25). The sealing buckle rod (25) is gradually pushed and buckled with the inclined surface of the inclined guide seat (15) corresponding to the inclined surface of the inclined guide seat (15), so that the stern door (2) is more tightly fitted to the outlet (11), achieving the effect of sealing and waterproofing.

The aforementioned embodiments or drawings do not limit the structural form of the present invention. Any appropriate changes or modifications by a person having ordinary knowledge in the relevant technical field should be deemed to be within the patent scope of the present invention.

In summary, the embodiments of this invention can achieve the expected effects of use, and the specific structure disclosed is not only not seen in similar products, but also has not been disclosed before the application. It fully complies with the provisions and requirements of the Patent Law. Therefore, an application for a new patent is filed in accordance with the law. I sincerely request your review and grant of the patent. I would really appreciate the convenience.
