Description

Technical Field

[0001] This utility model relates to the field of hatch cover lifting devices, specifically a hatch cover lifting device. Background Technology

[0002] A hatch cover lifting device is used to control the opening and closing of hatches. Ships that transport cargo are called freighters. Freighters have been sailing the oceans for thousands of years, enabling trade between different parts of the world. Today, a large variety of freighters sail the seas, from large oil tankers to small tugboats, from car ferries to ships specially designed for searching damaged vessels. Freighters rarely have a superstructure (the part above the main deck). The ship has a pilot's bridge with a funnel. Below the bridge are the engines and living quarters. The rest of the ship can accommodate as much cargo as possible.

[0003] Currently, hatch covers are generally opened and closed by side-opening. This method limits the size of the hatch, seriously affecting the loading and unloading of cargo. In addition, the hatch cover has a single function and cannot assist in suspending and fixing cargo during the opening process, making it inconvenient to load and unload cargo. Utility Model Content

[0008] In a further embodiment, a secondary hydraulic rod is provided on the top side of the connecting plate by means of a hinge, and the telescopic end of the secondary hydraulic rod is hinged to the ear bracket.

[0009] In a further embodiment, a control panel is provided on the top of the mounting side plate, and the output end of the control panel is electrically connected to the input ends of the main hydraulic rod, the auxiliary hydraulic rod, and the electric actuator.

[0010] In a further embodiment, the pad is provided with two mounting holes, and the hanging hook is threaded into the mounting holes by a screw head.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model is equipped with a hatch cover, a pad at the bottom of the hatch cover, and a detachable cargo hook at the bottom of the pad. The cargo can be hung conveniently, and the cargo can be lifted out during the opening process, which facilitates the loading and unloading of cargo and saves a lot of labor for picking up cargo.

[0013] 2. The hatch cover of this utility model is provided with a limiting plate at the top. The limiting plate is hinged to the connecting plate on one side by a connecting frame. An auxiliary hydraulic rod is provided above the hinge, which allows the hatch cover to be flipped and controlled. The hatch cover can also be moved open by an electric push rod, so as to avoid affecting the entry and exit of goods during the hatch cover opening process, making it more convenient to use.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figure 1-5 This utility model provides an embodiment of a hatch cover lifting device, including a hatch cover 1, a cargo hook 2, a control panel 5, an electric push rod 6, and a mounting side plate 7. The top of the hatch cover 1 is provided with a limiting plate 4. One end of the limiting plate 4 is hinged to a connecting plate 17 via a connecting frame 15. The end plate 18 at the end of the connecting plate 17 is connected to the telescopic end of the electric push rod 6. The cylinder end of the electric push rod 6 is located on the cylinder mounting port 12 on the mounting side plate 7. The mounting side plate 7 is connected to the wheel well main plate 10 via a mounting sleeve 8. The hatch cover 1 is sealed on the top of the cargo hatch opening 9, which is located on the wheel well main plate 10. The limiting plate 4 is used to install the main hydraulic rod 13. The hinge between the connecting frame 15 and the connecting plate 17 allows the limiting plate 4 to rotate the hatch cover 1 via the main hydraulic rod 13. The cylinder mounting port 12 facilitates the installation of the electric push rod 6.

[0022] A pad 3 is provided at the bottom center of the hatch cover 1. Cargo hooks 2 are provided on both sides of the bottom of the pad 3. Cargo can be suspended by the cargo hooks 2. The pad 3 has two mounting holes 11. The cargo hooks 2 are threaded into the mounting holes 11 by screw heads. The mounting holes 11 facilitate the installation of the cargo hooks 2. A main hydraulic rod 13 is provided at the top center of the limiting plate 4. The telescopic end of the main hydraulic rod 13 is connected to the hatch cover 1. An ear bracket 14 is provided on one side of the top of the limiting plate 4. The main hydraulic rod 13 is used to control the vertical lifting and lowering of the hatch cover 1.

[0023] A secondary hydraulic rod 16 is hinged to one side of the top of the connecting plate 17. The telescopic end of the secondary hydraulic rod 16 is hinged to the ear bracket 14. The secondary hydraulic rod 16 is used to control the flipping of the hatch cover 1. A control panel 5 is provided on the top of the mounting side plate 7.
