Description

Technical Field

[0001] This invention relates to the field of transfer equipment technology, specifically an amphibious transfer trolley. Background Technology

[0002] Amphibious yacht transport vehicles are specially designed transport tools to meet the needs of transporting yachts in different terrains and environments. Combining the features of land vehicles and water navigation technology, amphibious yacht transport vehicles can travel on both land and water, thus achieving flexible transport of yachts. They have advantages such as amphibious performance, strong load-bearing capacity, good maneuverability, and strong adaptability. With the continuous development of the yacht industry and the increasing demand for leisure and entertainment, the market demand for this type of transport vehicle is expected to further expand.

[0003] Chinese Patent Application No. CN202211665359.1 discloses an amphibious geotechnical engineering survey platform and its usage method. The patent includes at least one of the following beneficial technical effects: when it is necessary to expand the area of ​​the working platform, the two extension sections are driven to rotate to the horizontal by a drive device, thereby expanding the area of ​​the working platform to meet the survey requirements. The operation is convenient and simple. The buoyancy part can not only provide good support for the extension sections, but also increase the buoyancy of the survey platform, providing sufficient buoyancy for the survey platform to work in water. The movable frame is driven to rotate by the telescopic component, so that the movable frame is away from the mounting frame to realize the unfolding of the rain cover, thereby facilitating the provision of a rain shelter for the workers on the working platform in rainy weather. The movable frame is brought closer to the mounting frame by the telescopic component to realize the storage of the rain cover, which facilitates the guarantee of working space on the working platform.

[0004] Chinese patent application CN 202010348301.9 discloses an amphibious vehicle. This application allows for wheel-track interchange, enabling it to adapt to wet, soft, and slippery terrains such as snow, deserts, swamps, rivers, lakes, and coastlines, providing mobility and traction, and exhibiting good traversal capabilities on complex terrains. Furthermore, when the amphibious vehicle is navigating on water, the rear first track can be raised above the water jet propulsion system, thus not affecting the vehicle's performance on water. However, the following problems still exist in practical applications:

[0005] 1. When the amphibious yacht is transported and needs to be launched, the existing technologies all require launching through a waterway with a certain slope, which affects the quality and efficiency of launching and cannot meet the launching needs in any environment.

[0006] 2. Existing technologies have poor clamping and fixing effects on the side walls of amphibious yachts, with low clamping precision, which cannot meet the fixing requirements of amphibious yachts of different shapes and sizes, thus reducing the subsequent handling and lifting effects.

[0007] 3. During the process of the yacht moving on the trolley frame, the friction is large and the energy consumption is large. At the same time, it cannot be adjusted according to the size of the yacht.

[0008] Therefore, the present invention provides an amphibious transfer vehicle to solve the above problems. Summary of the Invention

[0034] The foregoing and other technical contents, features and effects of the present invention are described in conjunction with the appendix below. Figures 1 to 7 The detailed description of the embodiments will make this clear. All structural details mentioned in the following embodiments are based on the accompanying drawings.

[0035] Exemplary embodiments of the present invention will now be described with reference to the accompanying drawings.

[0036] This invention relates to an amphibious transport vehicle, comprising a vehicle frame 1. Two sets of wheel systems are connected to the lower end of the vehicle frame 1, enabling the vehicle frame 1 to slide. Each wheel system includes several symmetrically distributed wheel supports 2. A rotating frame 3 is rotatably connected to the lower end of each wheel support 2. A fixed frame 4 is connected to the lower end of each rotating frame 3. Wheels 5 are connected to the fixed frame 4. The driving force of the wheels 5 drives the vehicle frame 1 to move. The wheels 5 are connected to an external drive source.

[0037] The rotating frame 3 within the traveling wheel system is divided into two symmetrical groups. A connecting push rod 6 rotatably connects to each of the two adjacent rotating frames 3 in the same group. One end of the connecting push rod 6 is rotatably connected to a hydraulic telescopic rod 7, which is connected to a pressure supply system. The other end of the hydraulic telescopic rod 7 is rotatably connected to the trolley frame 1. Both the front and rear symmetrical hydraulic telescopic rods 7 are connected to a pressure supply system attached to the trolley frame 1. The pressure supply system enables the synchronous extension and retraction of the two symmetrical hydraulic telescopic rods 7. The extension and retraction of the hydraulic telescopic rods 7, in turn, drives the rotation of the rotating frame 3 via the connecting push rod 6. The rotation of the rotating frame 3, in turn, drives the rotation of the fixed frame 4 and the traveling wheels 5, thereby enabling the traveling wheels 5 to turn, and ultimately, the trolley frame 1 to turn during its travel.

[0038] Two parallel lifting structures are placed between the two connected rotating frames 3. The lifting mechanism is a conventional hydraulic lifting structure, which will not be described in detail here. The lifting structure is used to adjust the lifting and raising of the yacht placed on the trolley frame 1.

[0039] In this embodiment, the yacht equipment is placed on the upper end of the lifting mechanism. The lifting structure supports the yacht, and the drive source of the traveling wheel system is activated to drive the traveling wheels 5. The movement of the traveling wheels 5 drives the movement of the trolley frame 1, thereby realizing the transfer function. When it is necessary to turn the trolley frame 1, the rotation of the rotating frame 3 is adjusted by extending and retracting different hydraulic telescopic rods 7, thereby realizing the rotation of the traveling wheels 5. During the rotation of the traveling wheels 5, the trolley frame 1 is steered during its movement.

[0040] In order to raise the height of the yacht according to practical applications, this embodiment provides a lifting structure. Specifically, the lifting structure includes a hydraulic lifting mechanism 8 placed between the two rotating frames 3. The upper end of each hydraulic lifting mechanism 8 is fixedly connected to a support tray 9, and the upper end of each support tray 9 is connected to a lifting plate 10. The lifting plate 10 supports the yacht, and the hydraulic lifting mechanism 8 drives the lifting of the support tray 9, thereby realizing the lifting adjustment of the lifting plate 10.

[0041] During the travel of the walking wheel 5, when the walking wheel 5 is on a muddy road or wading through water, it is necessary to adaptively adjust the height between the walking wheel 5 and the trolley frame 1. Therefore, this embodiment provides an adjustment structure. Specifically, the lower end of the wheel bracket 2 is rotatably connected to an adjusting telescopic rod 11. The lower end of the adjusting telescopic rod 11 is rotatably connected to the fixed frame 4. The adjusting telescopic rod 11 is a hydraulic rod. The height of the walking wheel 5 can be adjusted by extending and retracting the adjusting telescopic rod 11.

[0042] To accommodate yachts of varying widths, this embodiment provides a structure for adjusting the width of the trolley frame 1. Specifically, the trolley frame 1 is divided into a front frame 13 and a rear frame 14, connected by an I-beam connecting beam 15. Both the front and rear frames are fixedly connected with limiting sleeves 16 that mate with the I-beam connecting beam 15. The limiting sleeves 16 connect the front and rear frames to the I-beam connecting beam 15. The limiting sleeves 16 have mounting holes 17, and the I-beam connecting beam 15 has several linearly arranged adjusting holes 18. The mounting holes 17 and adjusting holes 18 are bolted together. By using the bolts and the different mounting holes 17 and adjusting holes 18, the distance between the front and rear frames 13 and 14 can be adjusted, thus adapting to yachts of different widths.

[0043] To ensure that the support tray 9 can be adapted to different slopes, the support tray 9 and the hydraulic lifting mechanism 8 are rotatably connected. The upper end of the hydraulic lifting mechanism 8 is connected to a rotating base 19, and the rotating base 19 and the lower end of the support tray 9 are hinged to an elastic ball. During the process of supporting the yacht, the support tray 9 can be adaptively adjusted according to the shape of the yacht's outer wall. At the same time, the stability of the support between the support tray 9 and the yacht is ensured during the adjustment process, avoiding line contact support, which would lead to unstable support.

[0044] To prevent the yacht on the trolley frame 1 from shifting during transport, a structure for limiting the yacht is provided. Specifically, a positioning component is connected to the trolley frame 1. The positioning component includes several sets of symmetrically distributed positioning clamps 20. The positioning clamps 20 are symmetrically distributed in pairs, effectively limiting the yacht and preventing shifting. Each positioning clamp 20 includes a clamping frame 21 fixedly connected to the trolley frame 1. A lifting clamping rod 22 is slidably connected vertically to the clamping frame 21. The rod 22 and the clamping frame 21 are connected by a hydraulic telescopic rod 7. The extension and retraction of the clamping frame 21 is achieved by extending and retracting the hydraulic telescopic rod 7. A telescopic arm 23 is slidably connected to the lifting clamping rod 22. The telescopic arm 23 is a hydraulic telescopic rod 7. A limit control rod 24 is fixedly connected to the upper end of the telescopic arm 23. A positioning plate is fixedly connected to the upper end of the limit control rod 24. The positioning plate is made of elastic material. The position of the positioning plate is adjusted by extending and retracting the telescopic arm 23, thereby ensuring that the positioning plate effectively clamps the yacht.

[0045] When the trolley frame 1 moves through water, in order to ensure that the traveling wheels 5 can move forward better and make full use of the forward force during the rotation of the traveling wheels 5, several driving reinforcing ribs 26 are fixedly connected inside the hub of each traveling wheel 5. The driving reinforcing ribs 26 are spiral inclined. While the traveling wheels 5 rotate underwater, the driving reinforcing ribs 26 rotate to provide driving force for the trolley frame 1. The reinforcing ribs reinforce the hub of the traveling wheels 5 and also play a role in dispersing the water during the rotation, providing auxiliary power for the movement of the trolley frame 1.

[0046] To ensure that the yacht can smoothly glide to the middle position of the trolley frame 1 when placed on the upper end of the trolley frame 1, this embodiment provides a structure to reduce the yacht's sliding resistance. Specifically, a rubber plate 27 is fixedly connected to the upper end of the lifting platform 10. The rubber plate 27 is in direct contact with the outer wall of the yacht, increasing the friction between the rubber plate 27 and the yacht and preventing the yacht from shifting during transport. The lifting platform 10 has a hollow structure, and an adjusting plate 28 is connected inside the lifting platform 10. Several rolling balls 29 are rotatably connected to the adjusting plate 28. The rubber plate 27 has slots 30 that cooperate with the rolling balls 29. The rolling balls 29 pass through the slots 30 and cooperate with the slots 30. The rolling balls 29 contact the outer wall of the yacht. When the yacht is placed in the middle position of the trolley frame 1, the rolling balls 29 roll, reducing the yacht's sliding resistance and facilitating the transport of the yacht.

[0047] Meanwhile, the lifting pallet 10 has a hydraulic chamber inside, and the adjusting plate 28 is placed inside the hydraulic chamber. During the process of adjusting the pressure inside the hydraulic chamber, the lifting and lowering of the adjusting plate 28 is realized, thereby enabling the rolling ball 29 to extend out of the storage box inside the slot 30. When the rolling ball 29 is stored inside the slot 30, the rubber plate 27 is in direct contact with the yacht, thereby increasing the friction between the yacht and the rubber plate 27, thus preventing the yacht from shaking during the transfer process. At the same time, when the rolling ball 29 extends, it contacts the yacht, reducing the yacht's sliding resistance, thus facilitating the loading and unloading of the yacht.

[0048] The trolley frame 1 is connected to a hydraulic control system 31, which is connected to the pressure supply system. The hydraulic control system 31 controls all the hydraulic systems to ensure that each part works in an orderly manner.

[0049] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
