DETAILED DESCRIPTION
[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments.

[0023] An embodiment of the present application provides a cargo hold swing door for a deck transport ship, which can solve the problems in the prior art that the cargo hold door of a deck transport ship is bulky, difficult to open and close, and has a weak locking structure, which affects construction efficiency and safety.
[0024] Since the cargo door of the deck transport ship is heavy and the locking structure is not firm, there are problems such as difficulty in opening and closing the cargo door and unreliable locking structure, so a telescopic rod is hinged on the cargo door, and the other end of the telescopic rod is hinged to the coaming of the cargo hold, so that the opening and closing of the cargo door can be controlled by the telescopic rod, and a rotating assembly and a limiter are respectively arranged on the door body, and the locking or opening of the cargo door can be achieved by the clamping, abutting or separation of the rotating assembly and the limiter. In this way, the problems such as the heavy cargo door of the deck transport ship and the unfirm locking structure, difficulty in opening and closing the cargo door and unreliable locking structure are solved.
[0025] refer to Figure 1-4 A cargo hold swing door for a deck transport ship comprises: a coaming 4 having an opening; a door body 1 comprising two parts and located at the opening, the two parts of the door body 1 being hinged to the corresponding two sides of the coaming 4, and being hinged to telescopic members 3, respectively, the other end of the telescopic members 3 being hinged to the corresponding coaming 4; a stopper located on one part of the door body 1; a rotating assembly 2 located on the other part of the door body 1, and being engaged with or separated from the stopper.
[0026] The structure of the cargo hold swing door can improve the opening and closing efficiency of the cargo hold door and increase safety. When the door body 1 needs to be opened, the worker remotely controls the rotating assembly 2 to rotate so that it is separated from the limiter, thereby releasing the locked state of the door body 1, and then controls the telescopic member 3 by operation to drive the door body 1 to rotate and be in an open state; when the door body 1 needs to be closed, the telescopic member 3 is continued to be controlled by operation to drive the door body 1 to rotate and be in a closed state, and then the worker remotely controls the rotating assembly 2 to rotate so that it is engaged with the limiter, thereby locking the door body 1. The two parts of the door body 1 are also hinged with telescopic members 3 respectively, so that the movement of the door body 1 can be controlled more flexibly and smoothly when opening and closing the door body 1. The setting of the limiter and the rotating assembly 2 and the engagement, abutment or separation between them can ensure the locking or opening of the door body 1. The cooperation of the limiter and the rotating assembly 2 can realize a more intelligent locking method of the door body 1, thereby improving the functionality and stability of the cargo hold door.
[0027] In some preferred embodiments, the door body 1 includes a first door body 11 and a second door body 12; the rotating assembly 2 is arranged on the first door body 11; and the limiter is arranged on the second door body 12. Through this arrangement, the design structure is specifically optimized, and the rotating assembly 2 and the limiter are respectively arranged on the first door body 11 and the second door body 12, so that the intelligent control of the door body 1 can be better realized. Through such a layout, the rotating assembly 2 can be remotely rotated by the worker at an appropriate time, and can be engaged with or separated from the limiter to control the locking or opening of the door body, thereby ensuring the safe use and stability of the door body 1. This design scheme makes the operation of the cargo door more convenient and flexible, while reducing the possibility of workers operating it by hand, and improving the intelligence level of the system. In addition, in practical applications, these preferred embodiments can also better adapt to different operating environments and requirements, and improve the overall performance and reliability of the cargo door.

In this design, the design of the telescopic member 3 adopts a combination of the first oil cylinder 31 and the second oil cylinder 32, and the telescopic action of the door body is realized by the hinged connection between the oil cylinder and the door body and the enclosure. Specifically, one end of the first oil cylinder 31 is hinged to the first door body 11, and the other end is hinged to the corresponding enclosure 4, while one end of the second oil cylinder 32 is hinged to the second door body 12, and the other end is also hinged to the enclosure 4. Such a design enables the two oil cylinders to work together to achieve stable control of the door body 1 and smooth telescopic operation. Through the push and pull force of the oil cylinder, the opening and closing of the door body can be controlled, while ensuring the balance and stability of the door body during use. This structural design not only improves the reliability and safety of the cargo door, but also facilitates the automated control and intelligent application of the door body 1.
[0029] In some preferred embodiments, the telescopic member 3 further includes a hydraulic pump station 33 and a hydraulic pipe 34; the hydraulic pump station 33 is arranged around the enclosure 4, and is connected to the first oil cylinder 31 and the second oil cylinder 32 respectively through the hydraulic pipe 34. In this design, the function of the hydraulic pump station 33 is to provide hydraulic power for the oil cylinder to realize the control of the oil cylinder. The hydraulic pump station 33 is usually installed around the enclosure 4, so that the hydraulic pipe 34 can be more conveniently connected to each oil cylinder, while reducing the length of the hydraulic pipe 34, thereby improving the stability and working efficiency of the system. The hydraulic pump station 33 is connected to the first oil cylinder 31 and the second oil cylinder 32 respectively through the hydraulic pipe 34, and the hydraulic energy is transmitted to each oil cylinder to control the movement of the oil cylinder, thereby realizing the telescopic action of the door body 1. Through the combination of the hydraulic pump station 33 and the hydraulic pipe 34, the working pressure and flow of the oil cylinder can be more accurately controlled to ensure the smooth movement of the door body 1. In addition, the hydraulic system can also realize multi-point control, making the telescopic operation of the door body 1 more flexible and intelligent. The application of hydraulic technology in the telescopic member 3 not only improves the reliability and stability of the system, but also improves the performance and stretching smoothness of the door body 1, providing workers with a better user experience.
