Description

Technical Field

[0001] This invention belongs to the field of ship transportation technology, and relates to a ship support frame, and more particularly to a ship land transportation support frame. Background Technology

[0002] Yachts, as private, non-commercial recreational vessels, are mainly used for sightseeing, leisure and entertainment, and business receptions.

[0003] Because users need to operate yachts in different waters, yacht relocation is a frequent occurrence. Transporting yachts during relocation presents a challenge, and currently, transport pallets are commonly used for this purpose.

[0004] However, since yachts come in different types and vary in shape and size, transport racks of appropriate size must be arranged for each yacht before transportation. These transport racks need to be customized and have low reuse rates.

[0005] Moreover, since yachts generally have a rounded shape, in order to make the yacht and the transport frame fit together perfectly, it is often necessary to manually add sandbags between the yacht and the transport frame during the transport process to adjust the gap between them. This process often needs to be repeated, which is time-consuming, labor-intensive, and poses safety hazards.

[0006] Therefore, given the shortcomings of existing technologies, there is an urgent need to develop a new type of land transportation device suitable for various types of yachts. Summary of the Invention

[0007] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a land transport device suitable for various types of yachts. This device can be towed by a flatbed truck along with the yacht and is adaptable to different types of yachts, thereby realizing land transport of yachts by flatbed truck.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] A land transport device suitable for various types of yachts includes a rail plate and multiple yacht support frames mounted on the rail plate. The multiple yacht support frames are used to support the yacht from both sides. The yacht support frames are characterized in that they are longitudinally adjustable on the rail plate. Each yacht support frame includes a rail body, with two symmetrically arranged outer support frames on each side of the rail body. Each outer support frame is equipped with a height-adjustable double-arm support mechanism. Two symmetrically arranged inner support systems are also provided between the two sides of the rail body. The inner support systems are laterally adjustable on the rail body and are also height-adjustable. The double-arm support mechanisms and the inner support systems together provide support for the yacht.

[0010] Preferably, a longitudinal slide rail is provided on each side of the rail plate, and a longitudinal sliding block and an anti-slip lock are provided at both ends of the lower part of the rail body. The longitudinal sliding block fits into the longitudinal slide rail so that the rail body can move longitudinally on the rail plate, and the anti-slip lock can be inserted into the longitudinal sliding block to lock the rail body relative to the rail plate.

[0011] Preferably, the outer support frame includes a triangular outer support frame body, the outer support frame body is fixed on the rail body, and a rotating shaft and multiple locking holes are provided on the hypotenuse of the outer support frame body.

[0012] Preferably, the external double-arm support mechanism includes a forearm and a large arm. The lower end of the forearm is fitted with a bushing, and the top end is fitted with an external pressure support plate. The bushing is fitted on the rotating shaft frame. The upper end of the large arm is connected to the upper part of the forearm through the large arm rotating shaft, and the lower end can be snapped into the locking hole.

[0013] Preferably, the lower part of the external pressure support plate is connected to the top of the forearm via a forearm pivot.

[0014] Preferably, the internal support system includes a transverse slider that can move laterally within the rail body. The transverse slider has multiple protrusions, the height of each protrusion is adjustable, and the top of each protrusion is provided with an internal pressure support plate that can be angled.

[0015] Preferably, the rail body has two transverse tracks inside, and the transverse slider is disposed between the two transverse tracks. The transverse slider can move laterally between the two transverse tracks and can be clamped and fixed between the two transverse tracks.

[0016] Preferably, the inner sides of the rail body are each provided with a long groove, and each side of the rail body is also provided with a locking hole that communicates with the long groove. The transverse track includes a rail body, a sliding plate, and a locking plate. The sliding plate connects the rail body and the locking plate. The sliding plate is wedged into the long groove and can move longitudinally to adjust the distance between the two rail bodies. Each side of the transverse slider is provided with a protrusion that is embedded in the inner side of the rail body. A locking pin can be inserted into the locking hole, and after the locking pin is rotated, it can abut against the locking plate and the inner wall of the locking hole to lock the transverse slider between the two rail bodies.

[0017] Preferably, a spring bolt is provided inside each of the two ends of the rail body, and the inner support system further includes a spring, one end of which is sleeved on the spring bolt and the other end is connected to the outer end of the transverse slider.

[0018] Preferably, the internal pressure support plate includes a pressure plate, and the upper surface of the pressure plate is provided with a plurality of mounting holes, and each mounting hole is provided with a magnetic pressure sensor.

[0043] To solve the transportation problems existing in the land transportation of yachts in the prior art, the inventors, after long-term research, invented a land transportation device suitable for various types of yachts.

[0044] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0045] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0046] like Figure 1-5 As shown, the land transport device of the present invention suitable for various types of yachts includes a rail plate 1 and a plurality of yacht support frames disposed on the rail plate 1.

[0047] In use, the rail-mounted flatbed 1 can replace the ordinary flatbed towed by the flatbed truck, so that the flatbed truck can tow the rail-mounted flatbed 1 to move, thereby realizing the land transportation of the yacht through the flatbed truck.

[0048] The multiple yacht support frames are used to support the yacht from both sides. This support ensures the stability of the yacht during transportation.

[0049] In this invention, the yacht support frame includes a rail carrier 2. The rail carrier 2 is capable of longitudinal movement on the rail carrier plate 1, thereby enabling the yacht support frame to be longitudinally adjusted on the rail carrier plate 1.

[0050] Specifically, such as Figure 6 As shown, a longitudinal slide rail 11 is provided on each of the two sides of the rail-carrying plate 1. Meanwhile, as... Figure 7 As shown, the rail carrier 2 includes a rail carrier body 21, and both ends of the lower part of the rail carrier body 21 are provided with longitudinal sliding blocks 22 and anti-slip locks 23.

[0051] Among them, such as Figure 8 As shown, the longitudinal slider 22 is provided with a wedge part, which can fit into the longitudinal slide rail 11, so that the carrier body 2 can move longitudinally on the carrier plate 1 by means of the cooperation between the longitudinal slider 22 and the longitudinal slide rail 11.

[0052] like Figure 9 As shown, the anti-slip lock 23 has serrated protrusions to increase friction. After the rail body 2 is longitudinally adjusted to the appropriate position, the anti-slip lock 23 is inserted into the longitudinal sliding block 22 below the rail body 21, so that the serrated surface with serrated protrusions is pressed against the rail plate 1, thereby locking the rail body 2 relative to the rail plate 1. Therefore, in the event of sudden braking during transportation, the rail body 2 can be prevented from sliding relative to the rail plate 1, ensuring safety.

[0053] Preferably, the lower ends of the rail body 21 are provided with four longitudinal sliding blocks 22 and four anti-slip locks 23. The four longitudinal sliding blocks 22 and four anti-slip locks 23 are respectively located at the four corners of the lower part of the rail body 21, ensuring the smooth longitudinal movement of the rail body 2.

[0054] Continue to refer to Figure 7 The track body 2 has two symmetrically arranged outer support frames 3 on both sides, and each outer support frame 3 is equipped with an external double-arm support mechanism 4 that can be height adjusted.

[0055] Specifically, the outer support frame 3 includes a triangular outer support frame body 31, which is fixed to the rail carrier 2. One right-angled side of the triangular outer support frame body 31 is fixed to the rail carrier 2, and the other right-angled side faces outwards, causing its hypotenuse to slope inwards. The hypotenuse of the outer support frame body 31 has a pivot bracket 32 ​​and multiple locking holes 33.

[0056] like Figure 10As shown, the external double-arm support mechanism 4 includes a forearm 41 and a main arm 44. The lower end of the forearm 41 is fitted with a bushing 42, and the top end is fitted with an external pressure support plate 45. The bushing 42 is fitted onto the rotating shaft frame 32. The external pressure support plate 45 is used to support the bottom of the yacht. The upper end of the main arm 44 is connected to the upper part of the forearm 41 via a main arm rotating shaft 43, and the lower end can be engaged in the locking hole 33.

[0057] Therefore, when it is necessary to adjust the height of the external pressure support plate 45, it is only necessary to snap the lower end of the upper arm 44 into the different snap holes 33, so the adjustment is very convenient.

[0058] Preferably, the forearm 41 has a forearm pivot at its top, and the lower part of the external pressure support plate 45 is connected to the top of the forearm 41 via the forearm pivot. This allows the angle of the external pressure support plate 45 to be adjusted as needed, thus ensuring a better fit with the bottom of the yacht.

[0059] More preferably, the top end of the forearm 41 is also provided with a locking member. Thus, after the external pressure support plate 45 is adjusted to the correct angle, it is locked by the locking member to prevent it from rotating again.

[0060] Continue to refer to Figure 1-5 Two symmetrically arranged inner support systems 5 are also provided between the two sides of the rail carrier 2. The inner support systems 5 are adjustable laterally on the rail carrier 2 and also adjustable in height. In this invention, the outer double-arm support mechanism 4 and the inner support systems 5 together provide support for the yacht.

[0061] like Figure 17 and 18 As shown, the internal support system 5 includes a transverse slider 51. The transverse slider 51 is capable of moving laterally within the carrier rail 2. The transverse slider 51 is provided with multiple bosses 53. The height of each boss 53 is adjustable (for example, the boss 53 is a hydraulically controlled boss or a sleeve-type boss, so that its height can be adjusted), and the top of each boss 53 is provided with an angle-adjustable internal pressure support plate 54. The internal pressure support plate 54 is also used to support the bottom of the yacht.

[0062] Preferably, the transverse slider 51 is provided with nine protrusions 53 to facilitate better support.

[0063] In this invention, the track carrier 2 is equipped with two transverse tracks inside. For example... Figure 14 and 15As shown, the transverse slider 51 is disposed between the two transverse tracks. The transverse slider 51 is capable of moving laterally between the two transverse tracks and can be clamped and fixed between the two transverse tracks.

[0064] Specifically, such as Figure 7 , 11 As shown in Figures 1 and 12, each of the two sides of the inner side of the rail body 2 is provided with a long groove 26, and each of the two sides of the rail body 2 is also provided with a locking hole 24 that communicates with the long groove 26.

[0065] And, as Figure 13-15 As shown, the transverse track includes a track body 28, a sliding plate 29, and a locking plate 210. The sliding plate 29 connects the track body 28 and the locking plate 210.

[0066] The sliding plate 29 is wedged into the elongated groove 26. The sliding plate 29 is relatively narrow, and after being wedged into the elongated groove 26, it can move longitudinally to adjust the distance between the two track bodies 28.

[0067] like Figure 17 and 18 As shown, each side of the transverse slider 51 is provided with a protrusion 52 embedded in the inner side of the track body 28, so that the transverse slider 51 can move longitudinally relative to the track body 28.

[0068] Under normal circumstances, such as Figure 14 As shown, the lateral slider 51 is capable of moving laterally between the two track bodies 28.

[0069] After the horizontal sliding slider 51 is moved laterally to the appropriate position, the locking pin 211 is inserted into the locking hole 24 and the locking pin 211 is rotated.

[0070] like Figure 15 and 16 As shown, one end of the locking pin 211 has a protrusion. Thus, as... Figure 15 As shown, when the locking pin 211 is rotated, the protrusion abuts against the inner wall of the locking hole 24, causing the main body of the locking pin 211 to abut inward against the locking plate 210, and through the locking plate 210 to abut inward against the sliding plate 29 and the track body 28, so that the transverse slider 51 is firmly clamped between the two track bodies 28, thereby locking the transverse slider 51 relative to the track body 28.

[0071] Continue to refer to Figure 17 and 18Preferably, the top of the boss 53 is provided with a boss pivot 56, and the lower part of the inner pressure support plate 54 is connected to the top of the boss 53 through the boss pivot 56. Thus, the angle of the inner pressure support plate 54 can be adjusted as needed, thereby allowing it to better fit the bottom of the yacht.

[0072] More preferably, the top of the boss 53 is also provided with a locking member. Thus, after the internal pressure support plate 54 is adjusted to the correct angle, it is locked by the locking member to prevent it from rotating again.

[0073] Furthermore, preferably, such as Figure 7 As shown, a spring bolt 27 is provided inside each of the two ends of the rail body 2. Meanwhile, as... Figure 17 and 18 As shown, the internal support system 5 also includes a spring 55. One end of the spring 55 is sleeved on the spring bolt 27, and the other end is connected to the outer end of the transverse slider 51.

[0074] Therefore, when the yacht's hull is fixed to the transport device, the internal pressure support plate 54 is inclined, which will generate an outward lateral force on the internal pressure support plate 54. This lateral force compresses the spring 55, thereby allowing the transverse slider 51 to be subjected to an inward thrust, which in turn causes the internal pressure support plate 54 to contact or squeeze the yacht's hull.

[0075] like Figures 19-20 As shown, the inner pressure support plate 54 includes a pressure plate 541. The upper surface of the pressure plate 541 has multiple mounting holes 543, and each mounting hole 543 contains a magnetically attached pressure sensor 544. Therefore, when the pressure plate 541 contacts the bottom of the yacht, due to magnetic force, the pressure sensor 544 protrudes from the mounting hole 543 and adheres to the bottom of the boat. In this way, the pressure sensor 544 measures the pressure borne by each pressure plate 541 and can automatically adjust the height of the protrusion 53 according to the pressure borne by each pressure plate 541.

[0076] Preferably, the inner pressure support plate 54 also has two rings 542, which are disposed on the lower surface of the pressure plate 541 so as to be fitted onto the boss shaft 56.

[0077] In this invention, the structure of the external pressure support plate 45 is the same as that of the internal pressure support plate 54, and for the sake of simplicity, it will not be described in detail.

[0078] Meanwhile, in this invention, preferably, as follows: Figure 7 As shown, a rope threading body 25 is provided at each end of the track body 2.

[0079] like Figure 21 As shown, the rope-carrying body 25 has a rope hole 251. The tow rope can be looped onto the yacht and passed through the rope hole 251 and knotted to help secure the yacht.

[0080] Finally, in this invention, preferably, a shock-absorbing pad is affixed to the recessed portion in the center of the pressure plate 541 and the rail body 21 to prevent the yacht from being bumped during fixing and transportation.

[0081] When transporting yachts using the land transport device of the present invention, which is suitable for various types of yachts, the workflow is as follows:

[0082] 1. Assembly: When transporting a yacht, replace the flatbed towed by a regular flatbed truck with the aforementioned rail plate 1. Select an appropriate number of rail bodies 2 according to the yacht's length and slide them onto the rail plate 1. Simultaneously, slide the rail bodies 2 to the appropriate position, and then insert the anti-slip lock 23 into the slider 22 to lock the rail bodies 2 and prevent them from sliding forward or backward during braking and starting.

[0083] 2. Lifting and placement: Adjust each of the external double-arm support mechanisms 4 to the appropriate locking holes 33, lift the yacht above the carrier rail 2, adjust the height of the external double-arm support mechanisms 4 again, and after adjusting it appropriately, slowly place the yacht on the external pressure support plate 45 of the external double-arm support mechanism 4.

[0084] 3. Locking pin insertion: After the internal pressure support plate 54 in the inner support system 5 is pressed, the transverse slider 51 moves to both sides, and the spring 55 is compressed. After the spring stops moving, the locking pin 211 is inserted into the locking hole 24 of each rail body 2 and rotated to the left / right respectively to push the locking plate 210, locking the transverse slider 51 and preventing it from sliding.

[0085] 4. Adjusting the inner support system 5: Activating the pressure sensor 544 of the inner pressure support plate 54, each pressure support plate 54 on the boss 53 will adjust the height of the boss 53 according to the pressure displayed by the pressure sensor 544. When the sensed pressure is too low, the boss 53 will slowly rise; when the sensed pressure exceeds the limit, the boss 53 will slowly descend to a suitable height.

[0086] 5. Attach the towing rope: After the inner support system / 5 is adjusted, attach one end of the towing rope to the yacht railing, tighten it, and then tie the other end to the rope hole 251 on the rail body to secure it.

[0087] The yacht support frame of this invention, suitable for land transportation of various types of yachts, serves to support and stabilize the yacht, preventing it from swaying from side to side. When used with a flatbed truck, the entire transportation device and the yacht can be towed together, adapting to the land transportation needs of different yachts. Furthermore, the yacht support frame of this invention is adjustable longitudinally, laterally, and vertically, allowing it to be positioned appropriately to support the yacht. It is suitable not only for supporting yachts of different types, models, and sizes, but also provides more stable support.

[0088] The above embodiments of the present invention are merely examples for clearly illustrating the present invention and are not intended to limit the implementation of the present invention. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is impossible to exhaustively list all possible implementations here. All obvious variations or modifications derived from the technical solutions of the present invention are still within the protection scope of the present invention.
