Description

Technical Field

[0001] This utility model relates to the technical field of roll-on / roll-off frames, and more specifically to a roll-on / roll-off frame. Background Technology

[0002] The towing end of the roll-on / roll-off (Ro-Ro) frame engages with the towing gooseneck of the tractor unit, allowing the towing gooseneck to be guided into the interior of the towing end of the Ro-Ro frame through the towing inlet. Once the towing gooseneck is in position, it is lifted, and through mechanical engagement with the fishplate and anti-derailment post, a rigid connection is achieved between the tractor unit and the Ro-Ro frame. This causes the towing end of the Ro-Ro frame to lift off the ground, allowing the tractor unit to drive the Ro-Ro frame.

[0003] Current roll-on / roll-off frames are simply assembled from existing hot-rolled profiles. Their structure is reinforced with a large number of stiffeners, which causes stress to be indirectly transmitted to the main load-bearing components. This can easily lead to uneven stress distribution, local stress concentration, instability risk, and poor impact resistance.

[0004] Therefore, a roll-on / roll-off frame is needed to at least partially solve the above problems. Utility Model Content

[0005] The description of this utility model introduces a series of simplified concepts, which will be further explained in detail in the detailed description section. This description is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0007] According to the roll-on / roll-off frame of this utility model, the traction side beam extends upward to directly connect to the fishplate and end beam, so that the end beam, traction side beam, and reinforcing crossbeam form an integral frame structure. The lifting force of the fishplate on the traction gooseneck and the downward pressure of the anti-derailment column on the traction gooseneck can be directly transmitted to the main load-bearing components such as the traction side beam, end beam, and reinforcing crossbeam, making the stress distribution more uniform and avoiding stress concentration caused by redundant structures and redundant transmission chains.

[0013] Preferably, it further includes end reinforcement members, at least two of which are disposed within the end beam, and in the width direction, two of the at least two end reinforcement members are respectively disposed corresponding to the two fishtail plates.

[0014] Preferably, it further includes a guide post, which is connected to the inner side of the two traction side beams and located above the anti-detachment post.

[0015] Preferably, in the length direction, the guide post and the anti-detachment post are arranged correspondingly.

[0016] Preferably, the guide post has a guide surface facing the anti-detachment post, and the guide surface is inclined relative to both the horizontal and vertical directions.

[0017] Preferably, it further includes a guide plate connected to the two fishtail plates and the anti-detachment post, the guide plate extending gradually upward from the fishtail plates to the anti-detachment post.

[0018] Preferably, it also includes a crash barrier connected to the two fishplates and located on top of the traction inlet. Attached Figure Description

[0028] like Figure 1 As shown, this utility model discloses a roll-on / roll-off vehicle frame. Figure 2 and Figure 3 As shown, the roll-on / roll-off (Ro-Ro) frame includes fishplates 110, end beams 120, traction side beams 130, reinforcing crossbeams 140, and anti-derailment posts 150. Two fishplates 110 are located at the traction end 100 of the Ro-Ro frame and are spaced apart along the width direction of the Ro-Ro frame. A traction inlet 111 is provided between the two fishplates 110. The end beam 120 extends along the width direction of the Ro-Ro frame. The end beam 120 connects to the two fishplates 110 and is located above the fishplates 110. The traction side beams 130 extend along the length direction of the Ro-Ro frame. Two traction side beams 130 are spaced apart along the width direction of the Ro-Ro frame and are respectively connected to the two fishplates 110. Both traction side beams 130 extend upwards beyond the fishplates 110 along the height direction of the Ro-Ro frame and are both connected to the end beams 120. The reinforcing crossbeam 140 extends along the width of the roll-on / roll-off frame and is spaced apart from the fishplate 110 along the length of the roll-on / roll-off frame. The reinforcing crossbeam 140 is connected to the two traction side beams 130. The anti-detachment post 150 is disposed between the fishplate 110 and the reinforcing crossbeam 140 along the length of the roll-on / roll-off frame and is connected to the inner side of the two traction side beams 130.

[0029] According to the roll-on / roll-off frame of this utility model, the traction side beam 130 extends upward to directly connect to the fishplate 110 and the end beam 120, so that the end beam 120, the traction side beam 130, and the reinforcing crossbeam 140 form an integral frame structure. Figure 4 As shown, the lifting force of the traction gooseneck 10 on the fishtail plate 110 and the downward pressure of the traction gooseneck 10 on the anti-detachment column 150 can be directly transmitted to the main load-bearing components such as the traction side beam 130, end beam 120 and reinforcing crossbeam 140, making the stress distribution more uniform and avoiding stress concentration caused by redundant structures and redundant transmission chains.

[0030] like Figure 1 As shown, the roll-on / roll-off frame also includes side beams 230 extending along the length of the frame. Two side beams 230 are spaced apart along the width of the frame. End beams 120 and reinforcing crossbeams 140 are both connected to the two side beams 230 to further transmit forces to the side beams 230, thus dispersing the force. The anti-detachment post 150 can be constructed as a solid column to increase strength and prevent deformation under the action of the traction gooseneck 10.

[0031] like Figure 6 As shown, the traction side beam 130 is inclined relative to the length direction of the roll-on / roll-off frame. That is, the traction side beam 130 gradually extends inward from the fishplate 110 to the reinforcing crossbeam 140, and the two traction side beams 130 gradually approach each other from the fishplate 110 to the reinforcing crossbeam 140.

[0032] like Figure 3 and Figure 6As shown, the roll-on / roll-off frame also includes an additional crossbeam 160. The additional crossbeam 160 extends along the width of the roll-on / roll-off frame and connects to two traction side beams 130. Along the length of the roll-on / roll-off frame, the additional crossbeam 160 is located between the end beam 120 and the reinforcing crossbeam 140. The additional crossbeam 160 is located above the anti-derailment post 150. The additional crossbeam 160 connects to two side beams 230 to further transmit forces to the side beams 230.

[0033] like Figure 3 and Figure 5 As shown, the roll-on / roll-off frame also includes side beam reinforcements 131. Side beam reinforcements 131 extend along the height direction of the roll-on / roll-off frame. Side beam reinforcements 131 are connected to the outer side of the traction side beam 130 and the additional crossbeam 160. Two side beam reinforcements 131 are respectively disposed on the outer side of the two traction side beams 130. Side beam reinforcements 131 can bear the load, thereby increasing the strength of the traction side beam 130, and can also transfer the load on the traction side beam 130 to the additional crossbeam 160, further dispersing the load.

[0034] Preferably, such as Figure 3 As shown, along the length of the roll-on / roll-off frame, the additional crossbeam 160 and the side beam reinforcement 131 are both correspondingly arranged with the anti-detachment post 150. In other words, the additional crossbeam 160 is located directly above the anti-detachment post 150, and the projections of the anti-detachment post 150 and the additional crossbeam 160 along the height direction of the roll-on / roll-off frame at least partially overlap; the projections of the anti-detachment post 150 and the side beam reinforcement 131 along the width direction of the roll-on / roll-off frame at least partially overlap. Thus, the downward pressure on the anti-detachment post 150, after being transmitted to the traction side beam 130, can be further transmitted to the side beam reinforcement 131 and the additional crossbeam 160 via the shortest path.

[0035] like Figure 3 and Figure 7 As shown, in this embodiment, the upper surface of the traction beam 130 is flush with the upper surface of the reinforcing beam 140 and the upper surface of the additional beam 160, thereby increasing the moment of inertia of the traction beam 130 section and making the end beam 120, traction beam 130, additional beam 160 and reinforcing beam 140 form an integral frame structure, so that the force transmission is direct and stress concentration is avoided. Figure 6 As shown, in this embodiment, the additional crossbeam 160 includes a plurality of short beams. For example, the additional crossbeam 160 includes three short beams. Two of the three short beams are respectively connected to the outer sides of the two traction side beams 130, and the other short beam is connected to the inner side of the two traction side beams 130. That is, the two traction side beams 130 divide the additional crossbeam 160 into three segments.

[0036] Understandably, in embodiments not shown, the upper surface of the traction beam 130 is close to the upper surface of the reinforcing beam 140 and the upper surface of the additional beam 160. For example, the upper surface of the traction beam 130 may be lower than the upper surfaces of the reinforcing beam 140 and the additional beam 160. In this embodiment, the additional beam 160 is constructed as a single, integral piece. For example, the bottom of the additional beam 160 may have two openings for connecting the two traction beams respectively.

[0037] like Figure 7 As shown, both traction side beams 130 extend downwards along the height direction of the roll-on / roll-off frame beyond the reinforcing crossbeam 140. The roll-on / roll-off frame also includes support stiffeners 170. The support stiffeners 170 are connected to the bottom of the traction side beams 130 and the bottom of the reinforcing crossbeam 140 to increase the strength of the overall structure.

[0038] like Figure 3 As shown, both fishplates 110 extend downwards along the height of the roll-on / roll-off frame beyond the towing side beam 130. The roll-on / roll-off frame also includes reinforcing ribs 220. The reinforcing ribs 220 are connected to the bottom of the fishplates 110 and the bottom of the towing side beam 130 to increase the strength of the overall structure.

[0039] like Figure 3 As shown, in this embodiment, the end beam 120 includes a main body 122 and a cover plate 123. The main body 122 is constructed as a C-shaped beam with an outward opening. The cover plate 123 is connected to the main body 122 and covers the opening of the main body 122. This facilitates the installation of reinforcing components within the end beam 120. For example, the roll-on / roll-off frame also includes end reinforcements 121. At least two end reinforcements 121 are disposed within the end beam 120. The end reinforcements 121 can be connected to the main body 122 or the cover plate 123 first, and then the cover plate 123 can be connected to the main body 122. Figure 2 As shown, in the width direction of the roll-on / roll-off frame, two of the at least two end reinforcements 121 are respectively disposed corresponding to the two fishplates 110. That is, the projections of the end reinforcements 121 and the fishplates 110 along the height direction of the roll-on / roll-off frame at least partially overlap, so that when the lifting force on the fishplates 110 is transmitted to the end beams 120, the end reinforcements 121 can bear the force, thereby preventing deformation of the end beams 120. It is understood that, in embodiments not shown, the end beams 120 may also be constructed as a single piece, for example, using a hollow square tube.

[0040] like Figure 3As shown, the roll-on / roll-off frame also includes a guide post 180. The guide post 180 is connected to the inner side of the two traction side beams 130 and is located above the anti-detachment post 150. The guide post 180 has a guide surface 181 facing the anti-detachment post 150, and the guide surface 181 is inclined relative to both the horizontal and vertical directions to guide the traction gooseneck 10 of the tractor unit, so that the traction gooseneck 10 can be accurately positioned and engaged with the anti-detachment post 150 after being inserted into the traction inlet 111. Preferably, as... Figure 3 As shown, guide posts 180 and anti-detachment posts 150 are correspondingly arranged along the length of the roll-on / roll-off frame. In other words, guide posts 180 are located directly above anti-detachment posts 150, and the projections of guide posts 180 and anti-detachment posts 150 along the height direction of the roll-on / roll-off frame at least partially overlap, thereby allowing the force on anti-detachment posts 150 to be better transmitted to guide posts 180 through the traction side beam 130. Guide posts 180 can be constructed as solid columns, which simultaneously possess guiding and force-distributing functions, thereby increasing the overall structural strength.

[0041] Furthermore, along the length of the roll-on / roll-off frame, the additional crossbeam 160, guide post 180, side beam reinforcement 131, and anti-detachment post 150 are all correspondingly arranged, i.e., located in the same vertical plane, so that stress transmission is more uniform and stress concentration is better avoided.

[0042] The roll-on / roll-off frame also includes a guide plate 190. The guide plate 190 is connected to two fishplates 110 and anti-detachment posts 150. The guide plate 190 extends gradually upwards from the fishplates 110 to the anti-detachment posts 150. The guide plate 190, together with the two traction side beams 130, causes the traction inlet 111 to be configured as an inwardly tapering flared shape. The guide plate 190 guides the tractor's gooseneck 10 into the traction inlet 111 and engages with the anti-detachment posts 150.

[0043] like Figure 2 and Figure 3 As shown, the roll-on / roll-off frame also includes a crash barrier 210. The crash barrier 210 is connected to the two fishplates 110 and is located on top of the towing inlet 111. The crash barrier 210 is used to prevent the towing gooseneck 10 of the tractor from colliding with the end beam 120 and also to make it easier for the towing gooseneck 10 to enter the towing inlet 111.

[0044] like Figure 3 As shown, the reinforcing beam 140 can be constructed as a C-shaped beam, and the additional beam 160 can be constructed as a hollow square tube. For example... Figure 7 As shown, the traction side beam 130 can also be constructed as a C-shaped beam.

The terminology used herein is for descriptive purposes only and is not intended to limit the scope of the invention. Features described in one embodiment may be applied, alone or in combination with other features, to another embodiment, unless that feature is not applicable in that other embodiment or is otherwise stated.

[0046] This utility model has been described through the above embodiments. However, it should be understood that the above embodiments are only for illustrative purposes. This utility model is not limited to the above embodiments. Many variations and modifications can be made based on the teachings of this utility model, and all such variations and modifications fall within the scope of protection claimed by this utility model.
