Description

Technical Field

[0001] This utility model relates to the field of transportation equipment technology, specifically a self-propelled amphibious rapid transport vehicle for yachts. Background Technology

[0002] A yacht is a vessel equipped with a mechanical propulsion system, used solely by the yacht owner for sightseeing, leisure, and entertainment activities.

[0003] As a typical imported sport, yachting has gradually gained recognition among Chinese people with the development of China's economy and the improvement of living standards. Domestic yacht clubs have gradually emerged. However, due to the constraints of consumption conditions, natural conditions, and lagging legal regulations, there are still significant shortcomings in the yacht transportation and hoisting process. The existing yacht transportation methods are mainly divided into land transportation and sea transportation. Land transportation relies on special flatbed trucks or trailers, which can only achieve land travel and cannot adapt to amphibious transportation scenarios. In particular, when launching or landing yachts, external hoisting equipment is required, which is cumbersome and inefficient. The yacht fixing devices of existing transport vehicles are mostly simple frame structures, lacking anti-slip support surfaces and adjustable fixing brackets, which makes the hull prone to swaying or shifting during transportation. Although some small trailers are equipped with basic support components, they are difficult to meet the transportation needs of medium and large yachts. Domestic hoisting equipment and facilities are backward, and most scenarios rely on single-point lifting by truck cranes, which is difficult to operate and has a high accident rate. The popularity of professional davits is extremely low, which further restricts the safety and convenience of yacht transportation. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1, please refer to Figures 1-4 In this embodiment of the utility model, a self-propelled amphibious rapid transport vehicle for yachts includes a chassis frame 100, a yacht fixing device 110 on the top of the chassis frame 100, the yacht fixing device 110 including an anti-slip support surface 111 and a fixing bracket 112, a first traveling wheel 200 and a second traveling wheel 220 below the chassis frame 100, the first traveling wheel 200 and the second traveling wheel 220 being connected to a steering mechanism 120 at the front end of the chassis frame 100 via an axle 210, a support frame 130 and a motor 140 on the left side of the chassis frame 100, a traction device 300 at the front end of the support frame 130, the traction device 300 including a traction rope 310 and a traction hook 320, a chassis fixing bracket 150 at the bottom of the chassis frame 100, and fixing holes 151 at the rear of the chassis frame 100. The modular design enables amphibious transport functionality, with a compact overall layout and convenient operation.

[0024] Specifically, the yacht fixing device 110 includes an anti-slip support surface 111 and a fixing bracket 112. The anti-slip support surface 111 is made of metal sheet, and the fixing bracket 112 is welded and fixed to the anti-slip support surface 111. The yacht fixing device 110 is symmetrically distributed on both sides of the chassis frame 100. The steering mechanism 120 includes a steering linkage and a steering shaft. The steering shaft is laterally located at the lower end of the chassis frame 100. One end of the steering shaft is connected to the axle 210 of the first traveling wheel 200 by a key, and the other end extends to the second traveling wheel 220. The towing hook 320 of the towing device 300 has a hook-shaped structure. Its root is welded to the crossbeam at the front end of the chassis frame 100. One end of the towing rope 310 is tied and fixed to the top of the hook of the towing hook 320, and the other end is wrapped in the rope wheel groove at the front end of the chassis frame 100. The support frame 130 is a square column, and its top is connected to the left and right side walls of the chassis frame 100 by hinges. The motor 140 is covered with a metal protective cover, and the bottom of the protective cover is fixed to the crossbeam of the support frame 130 by bolts. The output shaft of the motor 140 is connected to the middle of the axle 210 by a coupling. The chassis fixing bracket 150 is an elliptical steel plate. The vertical section is welded to the bottom of the chassis frame 100, and the horizontal section extends outward. The fixing hole 151 is a circular through hole, which is opened at the tail end of the chassis frame 100. There is one fixing hole on each side. The axle 210 is a solid cylindrical structure. Its two ends pass through the hubs of the first traveling wheel 200 and the second traveling wheel 220, respectively. The axle 210 is connected to the hub by bearings. The outer surface of the axle 210 is coated with a zinc layer.

[0025] like Figure 1 As shown, in this embodiment, the chassis frame 100 is welded from rectangular steel pipes, and the frame is reinforced internally by cross-shaped stiffeners to enhance the overall load-bearing capacity. The yacht fixing device 110 is installed in the upper central area of ​​the chassis frame 100. The anti-slip support surface 111 is made of stainless steel plate, and the surface is sandblasted to form a diamond pattern, which can increase the friction coefficient between the yacht and the support surface and effectively prevent the hull from sliding laterally during transportation. The fixing bracket 112 is a U-shaped frame made of bent carbon steel, and its bottom end is fixed to the anti-slip support surface 111 by welding. The weld is ground and polished to avoid sharp edges damaging the yacht surface.

[0026] like Figure 2 As shown, in this embodiment, both the first traveling wheel 200 and the second traveling wheel 220 use radial tires specifically designed for engineering machinery, with wheel hubs made of cast aluminum. The axle 210 is a solid cylinder forged from alloy structural steel, and its outer surface is coated with a zinc layer through a hot-dip galvanizing process to improve its resistance to salt spray corrosion. The axle 210 is connected to the wheel hub via a tapered roller bearing, which can withstand the combined effects of radial and axial loads, ensuring smooth rotation of the axle during driving.

[0027] like Figure 1 and Figure 3As shown, in this embodiment, the steering shaft of the steering mechanism 120 is made of carbon steel, and one end of it is connected to the wheel axle 210 of the first traveling wheel 200 through a flat key; the steering linkage is a "V" shaped structure made of seamless steel pipe bent into shape, and both ends are connected to the steering shaft and the chassis frame 100 through ball joint bearings, which can realize multi-directional rotation and reduce mechanical jamming during the steering process.

[0028] like Figure 4 As shown, in this embodiment, the traction hook 320 of the traction device 300 is forged and has a "J"-shaped hook structure. Its root is fixed to the crossbeam at the front end of the chassis frame 100 by submerged arc welding. The traction rope 310 is a polyester industrial filament rope. One end of the rope is fixed to the top of the traction hook 320 by a stainless steel rope clip, and the other end is wound in the groove of the nylon rope wheel at the front end of the chassis frame 100. The release and retraction of the traction rope can be controlled by a manual crank.

[0029] like Figure 2 and Figure 4 As shown, in this embodiment, the support frame 130 is made of square tubing, and its top end is connected to the left and right side walls of the chassis frame 100 through stainless steel hinges, which can achieve multi-angle rotation; the bottom of the support frame 130 is provided with a circular rubber pad. When the transport vehicle is parked, the support frame 130 can be driven by a hydraulic cylinder to support downward to the ground, forming a multi-point support structure together with the traveling wheels, reducing the pressure on the ground and adapting to the parking needs of soft road surfaces.

[0030] like Figure 1 As shown, in this embodiment, the motor 140 is a permanent magnet synchronous motor, with an external steel plate protective cover. The surface of the protective cover has louvered ventilation holes to ensure the motor's operating temperature is controlled within a reasonable range. The bottom of the protective cover is fixed to the crossbeam of the support frame 130 by bolts to prevent the bolts from loosening due to vibrations generated during motor operation. The output shaft of the motor 140 is connected to the wheel axle 210 via a flexible pin coupling, which can compensate for installation errors and absorb vibrations, improving the stability of the transmission system.

[0031] like Figure 1 and Figure 2 As shown, in this embodiment, the chassis mounting bracket 150 is an elliptical structure made of stamped steel plate. Its vertical section is welded to the bottom of the chassis frame 100 by fillet welds; the horizontal section extends outward, and the mounting hole 151 is opened at the end of the horizontal section. The hole wall is chamfered to remove burrs, making it easy for bolts to be inserted. When the transport vehicle is in amphibious operation, the mounting bracket for the underwater propulsion device can be installed through the mounting hole 151, realizing rapid switching between the amphibious and land propulsion systems.

[0032] In this embodiment, the fixing holes 151 at the rear end of the chassis frame 100 are symmetrically distributed, compatible with the connection holes of standard yacht trailers. They can be combined with other transportation equipment using high-strength bolts to expand transportation capabilities in multiple scenarios. Brass bushings are embedded inside the fixing holes 151 to reduce wear between the bolts and the hole walls, extending their service life.

[0033] like Figure 3 As shown, in this embodiment, the bearing between the axle 210 and the hub is axially positioned by a shaft elastic retaining ring and a bore elastic retaining ring to ensure that the bearing does not move axially during operation. The outer ring of the bearing is interference-fitted with the hub, and the inner ring is transition-fitted with the axle to ensure the normal operating clearance of the bearing. Both ends of the axle 210 are sealed with dust covers to prevent mud and seawater from entering the bearing and extend the maintenance cycle.

[0034] Beneficial Effects: This embodiment improves hull stability during transportation by optimizing the material and structural design of the yacht's securing device; the use of high-strength alloy materials and anti-corrosion treatment extends the service life of key components in the marine environment; the precise coordination of the steering mechanism and the walking system ensures flexibility for both road travel and on-site turning; and the multi-functional design of the towing device and support frame expands the equipment's applicable scenarios. The overall structure is compact and highly modular, facilitating manufacturing and maintenance, and can meet the integrated needs of transporting yachts from land to water, effectively reducing the operational complexity of traditional transportation methods that rely on the coordination of multiple devices.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
