Description

Technical Field

[0001] This utility model relates to the field of ship transportation equipment technology, specifically to an amphibious transport vessel frame for loading and unloading ships. Background Technology

[0002] In various fields such as water conservancy projects, water environment monitoring, and maritime operations, small vessels are frequently used for short-distance material transportation, equipment deployment, and personnel transfer. Small vessels are characterized by their compact size and maneuverability, enabling them to navigate easily in narrow waters and shallow areas that are difficult for larger vessels to access, thus providing strong support for various maritime operations.

[0003] However, small vessels face numerous challenges during loading and unloading. Firstly, their relatively light weight makes them susceptible to capsizing during loading due to water currents or unstable placement, potentially damaging the vessel and endangering the lives of operators. Secondly, removing small vessels from the water requires multiple people to lift them due to their slippery hull, resulting in strenuous labor and a risk of injury. Therefore, developing equipment to solve the loading and unloading problems of small vessels is urgently needed. Utility Model Content

[0004] The purpose of this utility model is to provide an amphibious transport vessel frame for loading and unloading ships, so as to solve the problems of easy capsizing and high labor intensity of loading and unloading of existing small ships during the process of entering and leaving the water.

[0005] To solve the above-mentioned technical problems, the present invention provides an amphibious transport vessel frame for loading and unloading ships, comprising a mobile chassis, a control box, and a vessel frame body. The mobile chassis has four wheels connected to its four corners, and one side of the mobile chassis is fixedly connected to the control box. A movable arm is rotatably connected to one side of the upper part of the mobile chassis, and the other end of the movable arm is rotatably connected to the mobile chassis via a first hydraulic cylinder. The top of the movable arm is rotatably connected to one side of the bottom of the vessel frame body, and the other side of the bottom of the vessel frame body is rotatably connected to the mobile chassis via a second hydraulic cylinder. Both the vessel frame body and the mobile chassis are frame structures. The vessel frame body is composed of a main frame and side frames rotatably connected on both sides. The main frame has a main positioning post on the side closest to the control box, and multiple side positioning posts are provided on the side frames.

[0006] As a preferred embodiment of this utility model, the driving method of the movable wheel is a dual front wheel hydraulic motor, and the movable wheel is a solid tire.

[0007] As a preferred technical solution of this utility model, the control box integrates a battery, a motor and a hydraulic system, and the top of the control box is provided with an operating equipment placement rack, wherein the motor is used to drive the hydraulic system, and the hydraulic system is connected to the first hydraulic cylinder, the second hydraulic cylinder and the moving wheels.

[0008] As a preferred embodiment of this utility model, the number of movable arms is two, and the movable arms are symmetrically arranged on both sides of the mobile chassis.

[0009] As a preferred technical solution of this utility model, a rotating seat is provided at the connection between the movable arm and the movable chassis and the ship frame body, and the height of the rotating seat matches the height of the movable arm. The rotating seats at the bottom of the ship frame body are located on both sides of the bottom of the main frame.

[0010] As a preferred embodiment of this utility model, the number of the second hydraulic cylinder is one, and the positions of the second hydraulic cylinder and the first hydraulic cylinder are symmetrically arranged.

[0011] As a preferred embodiment of this utility model, there are two main positioning columns, which are symmetrically arranged on the main frame, and the connection between the second hydraulic cylinder and the ship frame body is located in the middle of the two main positioning columns.

[0012] As a preferred embodiment of this utility model, the height of the side positioning post is 3 / 4 to 4 / 5 of the height of the main positioning post, and the main positioning post and the side positioning post are staggered to prevent collision during folding.

[0013] As a preferred technical solution of this utility model, one side of the side positioning column is provided with a corresponding support frame on the side frame and the main frame, and a V-shaped placement structure is formed between the two support frames.

[0014] The advantages of this utility model compared with the prior art are as follows:

[0015] 1. This amphibious transport vessel frame achieves automated lifting and lowering of the vessel body through the cooperation of the movable chassis and the movable arm, as well as the drive of the first and second hydraulic cylinders. This allows the hull to be horizontally lifted at positions such as the ramps for entering and exiting the water, keeping the hull on the water surface. Operators can operate the vessel directly while sitting on the hull, reducing the labor intensity during the loading and unloading process of small vessels and improving loading and unloading efficiency.

[0016] 2. The amphibious transport vessel frame effectively increases the contact area and stability with small vessels through the unique frame structure of the frame body and the design of the main positioning column, side positioning column and support frame. This avoids the small vessels from capsizing and colliding during loading and unloading, ensuring the safety of the vessel and the operators. In addition, the folding mechanism makes it easy to store. Attached Figure Description

[0025] Example 1:

[0026] As per the instruction manual Figure 1-4 As shown, an amphibious transport vessel frame for loading and unloading ships includes a mobile chassis 1, a control box 2, and a frame body 3.

[0027] In this utility model, each of the four corners of the mobile chassis 1 is connected to a mobile wheel 4. The mobile wheel 4 is driven by a dual front wheel hydraulic motor and is a solid tire. One side of the mobile chassis 1 is fixedly connected to the control box 2 to support the control box 2. The control box 2 integrates a battery, a motor, and a hydraulic system. The top of the control box 2 is equipped with an operating equipment placement rack 12. The motor is used to drive the hydraulic system, which is connected to the first hydraulic cylinder 6, the second hydraulic cylinder 7, and the mobile wheel 4. The motor is a 10.3kw AC motor, the battery is a 48V / 205Ah lithium battery, and the hydraulic system is approximately 25 liters.

[0028] In this utility model, a movable arm 5 is rotatably connected to one side of the upper part of the movable chassis 1, and the other end of the movable arm 5 is rotatably connected to the movable chassis 1 through a first hydraulic cylinder 6; the top of the movable arm 5 is rotatably connected to one side of the bottom of the boat frame body 3, and the other side of the bottom of the boat frame body 3 is rotatably connected to the movable chassis 1 through a second hydraulic cylinder 7. There are two movable arms 5, and the movable arms 5 are symmetrically arranged on both sides of the movable chassis 1. There is one second hydraulic cylinder 7, and the positions of the second hydraulic cylinder 7 and the first hydraulic cylinder 6 are symmetrically arranged.

[0029] In this utility model, both the ship frame body 3 and the mobile chassis 1 are frame structures. The ship frame body 3 is composed of a main frame 8 and side frames 9 rotatably connected on both sides. The main frame 8 has two main positioning columns 10 located on the side near the control box 2. The main positioning columns 10 are symmetrically arranged on the main frame 8. The connection between the second hydraulic cylinder 7 and the ship frame body 3 is located in the middle of the two main positioning columns 10. The side frame 9 has multiple side positioning columns 11. The height of the side positioning columns 11 is 3 / 4 to 4 / 5 of the height of the main positioning columns 10. The main positioning columns 10 and the side positioning columns 11 are staggered to prevent collisions during folding. One side of the side positioning column 11 is provided with a corresponding support frame 14 on the side frame and the main frame 8. The two support frames 14 form a V-shaped placement structure.

[0030] Example 2:

[0031] When a small boat needs to be placed in the water, the first hydraulic cylinder 6 and the second hydraulic cylinder 7 are activated by operating the control device. The second hydraulic cylinder 7 extends to lift one end of the boat frame body 3. At the same time, the first hydraulic cylinder 6 extends to slowly tilt and lift the boat frame body 3, keeping it horizontal until the boat is smoothly placed into the water. During the placement process, the boat's entry position can be precisely adjusted by the movement function of the mobile chassis 1.

[0032] When the small boat needs to be taken ashore after use, first move the boat to a suitable position on the frame body 3, then move it to a suitable landing location via the mobile chassis 1, then control the first hydraulic cylinder 6 and the second hydraulic cylinder 7 to move in opposite directions, first raise the frame body 3 to a horizontal state, then slowly position the boat with the main positioning column 10 and the side positioning column 11, then move the boat along the shore via the mobile chassis 1 until the boat is completely out of the water, and finally use the mobile wheels 4 to transport the boat to the designated storage location.

[0033] When the equipment is not in use, for easy storage and transportation, the first hydraulic cylinder 6 and the second hydraulic cylinder 7 are operated by the control device to retract, so that the movable arm 5 and the frame body 3 are folded into a suitable storage state. Since the main positioning column 10 and the side positioning column 11 are staggered, and the second hydraulic cylinder 7 and the first hydraulic cylinder 6 are symmetrically positioned, no collision will occur during the process of folding the side frame 9 inward, ensuring the safety and service life of the equipment.

[0034] In its specific implementation, this utility model utilizes a hydraulic system to control the frame body 3, thereby completing the loading and unloading of small vessels. The electric motor within the control box 2 provides power to the hydraulic system, which controls the extension and retraction of the first hydraulic cylinder 6 and the second hydraulic cylinder 7 to change the position and angle of the movable arm 5 and the frame body 3. When the first hydraulic cylinder 6 and the second hydraulic cylinder 7 work together, they can precisely control the lifting and tilting angles of the frame body 3, enabling it to smoothly support and move small vessels. The moving wheels 4 on the mobile chassis 1 are responsible for the overall movement of the equipment, ensuring accurate adjustment of the vessel's position during loading and unloading. The main frame 8, side frames 9, main positioning columns 10, side positioning columns 11, and support frame 14 of the frame body 3 work together to provide stable support and positioning for the small vessels, ensuring the safety and stability of the loading and unloading process.

[0035] The present invention and its embodiments have been described above. This description is not restrictive, and the specific embodiments shown are only one of the embodiments of the present invention. The actual structure is not limited to this. In short, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
