Description

Technical Field

[0001] This utility model relates to the field of vehicle transportation equipment technology, and in particular to a vehicle transport vehicle sinking and fixing bridge plate. Background Technology

[0002] In the vehicle transportation industry, especially in the field of center-axle vehicle transport trains, these trains, as specialized trains for transporting commercial vehicles, consist of a front car (vehicle transport car) and a rear car (vehicle transport trailer). The upper platform of the vehicle transport trailer plays a crucial role in placing the vehicles to be transported. The safe and smooth loading and unloading operations on the upper platform rely on a specially designed lifting device between the upper platform and the lower frame. This device is extremely important for the lifting and lowering control of the upper platform.

[0003] Currently, most commercially available vehicle transport trailers employ a specific technical solution to achieve upper platform lifting functionality. This involves welding a set of wide uprights onto the lower frame. These uprights typically have a C-shaped cross-section, and hydraulic cylinders are housed inside. The lower part of the cylinder is hinged to the upright, while the upper part connects to a slider built into the upright. This slider is then hinged to the upper platform. The extension and retraction of the hydraulic cylinders causes the slider to slide within the upright, thus raising and lowering the upper platform. For example, a similar structure is used in patent documents [specific patent name]. However, these existing platform lifting devices have revealed a series of significant drawbacks in practical applications.

[0004] Because the hydraulic cylinder is built into the column, its installation is extremely inconvenient, making the entire device complex and bulky, requiring a large amount of materials and resulting in poor economic efficiency. Furthermore, the width of vehicle transport trailers is limited, and these wide columns occupy too much usable space in the width direction, affecting the design of the trailer's effective width space and making it difficult to meet increasingly stringent transportation standards and the demands for efficient transportation. Moreover, the guide blocks and slide rails in traditional structures often rely on moving friction, which easily wears down after prolonged use, resulting in poor reliability. During transportation, if the guide blocks or slide rails malfunction, it may cause instability in the lifting and lowering of the upper platform, or even jamming, seriously affecting transportation safety and efficiency.

[0005] Furthermore, some traditional lifting devices struggle to achieve precise lifting control when handling vehicles of varying weights and center of gravity. When carrying heavy vehicles, issues may arise such as excessive platform descent or insufficient lifting speed; conversely, when transporting light vehicles, over-lifting may occur. This not only affects the safety and convenience of vehicle loading and unloading but may also cause unnecessary damage to the vehicle. Moreover, due to structural design limitations, some lifting devices are prone to component loosening and deformation after prolonged use, requiring frequent maintenance and further increasing operating costs.

[0006] In conclusion, it is urgent to develop a vehicle transport trailer sunken bridge deck technology that can achieve stable lifting and lowering adjustment of the bridge deck body, accurately adapt to vehicles with different chassis heights, ensure safe and reliable lifting process, convenient and efficient operation, and meet transportation compliance requirements.

[0011] Preferably, a first mounting beam and a second mounting beam are provided between the first crossbeam and the continuous crossbeam, and between the second crossbeam and the continuous crossbeam; the bottom of the first mounting beam and the second mounting beam are respectively provided with a first set of hinge seats and a second set of hinge seats that are hinged to the first set of sinking oil cylinders and the second set of sinking oil cylinders; the first set of hinge seats and the second set of hinge seats have the same structural configuration.

[0012] Preferably, the first set of sinking cylinders and the second set of sinking cylinders are hinged to the transport vehicle through the third set of hinge seats and the fourth set of hinge seats, respectively; the third set of hinge seats and the fourth set of hinge seats have the same structural configuration.

[0018] The vehicle transport vehicle sinking and fixing bridge plate provided by this utility model has the following beneficial effects:

[0019] In this invention, the technical solution achieves the lifting and lowering of the bridge deck body through the alternating operation of the first and second sets of sinking hydraulic cylinders. This effectively avoids the problem of bridge deck tilting and swaying caused by uneven force distribution due to a single or synchronously driven hydraulic cylinder, significantly improving the stability and safety of the lifting process and reducing the risk of displacement of the transported vehicle, chassis scraping, and rollover. The articulated cooperation between the two sets of sinking hydraulic cylinders and the bridge deck body and transport vehicle, combined with the articulated design of the bridge deck body with the transport vehicle through the first and second supports, allows for precise adjustment of the bridge deck height, flexibly adapting to different needs. For vehicles with the same chassis height, the slope of the upper and lower bridge decks is reduced, improving loading adaptability and efficiency. The main body of the bridge deck adopts a combination structure of the first longitudinal beam, the second longitudinal beam, and multiple sets of cross beams and continuous beams, and is equipped with reinforcing components such as reinforcing plates, which can enhance overall rigidity, evenly distribute loads, and improve load-bearing capacity and durability. The setting of multiple sets of hinge seats and hinge shafts simplifies the connection structure between the bridge deck and the transport vehicle, facilitating quick installation and operation. At the same time, by precisely controlling the height of the bridge deck, it can be ensured that the overall height of the vehicle and the axle load distribution comply with road transport regulations and meet compliance requirements.

[0028] Example 1

[0029] Please see Figure 1 This utility model provides a sunken fixed bridge plate for a vehicle transport vehicle. The sunken bridge plate is installed in the vehicle transport vehicle primarily to adapt to the characteristics and needs of motor vehicle transportation. On one hand, it significantly reduces the height of the loading platform, decreases the slope when vehicles are loaded and unloaded, and prevents scraping of passenger vehicles such as sedans and SUVs with low chassis when loading and unloading. It also reduces the overall height of large vehicles after loading, ensuring compliance with road height restrictions. On the other hand, by flexibly adjusting the height, multi-layer loading can be achieved, increasing the single-transport capacity. It also optimizes the center of gravity distribution of the transported vehicles, enhances driving stability, reduces the risk of rollover, and evenly distributes weight to each axle, complying with axle load distribution regulations and ensuring transportation safety and compliance.

[0030] Compliance primarily refers to the requirement that the fixed bridge deck of the vehicle transport vehicle must comply with relevant road transport regulations regarding the vehicle's overall height and axle load distribution during use. Specifically, by precisely controlling the lifting height of the bridge deck body 100, it can be ensured that the total height of the entire vehicle (including the transported vehicle) does not exceed the road height limit. Simultaneously, the bridge deck's structural design evenly distributes the weight of the transported vehicle across all axles, preventing excessive load on any single axle, thus meeting traffic regulations for oversized and overweight transport and ensuring the legality and compliance of the transport activities.

[0031] Please see Figure 1 This embodiment provides a sunken bridge deck for a vehicle transport vehicle; it includes a bridge deck body 100 and a first set of sinking cylinders 110 and a second set of sinking cylinders 120 disposed at both ends of the bridge deck body 100 and hinged to the bridge deck body 100; the first set of sinking cylinders 110 and the second set of sinking cylinders 120 are respectively hinged to the transport vehicle; one end of the bridge deck body 100 is hinged to the transport vehicle through a first support 121 and a second support 122 respectively; each of the first set of sinking cylinders 110 and the second set of sinking cylinders 120 includes a pair of sinking cylinders 123 disposed on both sides of the bottom of the bridge deck body 100; the first set of sinking cylinders 110 and the second set of sinking cylinders 120 work alternately to realize the raising or lowering of the bridge deck body 100.

[0032] Further, please see Figure 1 and Figure 3 The first set of sinking cylinders 110 and the second set of sinking cylinders 120 are inclined. One end of their cylinder bodies is hinged to the corresponding hinge seat of the transport vehicle, and one end of the piston rod is inclined upward and hinged to the hinge seats on the first mounting beam 141 and the second mounting beam 142 at the bottom of the bridge plate body 100. The two sets of cylinders are symmetrically distributed on both sides of the bottom of the bridge plate body 100, and the inclination direction forms a certain angle with the length direction of the bridge plate body 100. This inclined layout allows the cylinders to decompose the driving force into vertical lifting or lowering force to drive the bridge plate body 100 to rise and fall during telescopic operation. It can also enhance the stability of the connection between the bridge plate and the transport vehicle through the horizontal component force. At the same time, the inclination angle is adapted to the rotation trajectory of the bridge plate body 100 to avoid motion interference with other components, providing a structural basis for the alternating operation of the two sets of cylinders.

[0033] The core function of a lowered bridge deck is to adjust its height to accommodate the loading and unloading needs of different vehicles (such as low-chassis cars and high-chassis trucks). When the inclined drive unit exerts force, its driving force can be decomposed into a vertical lifting force and a horizontal auxiliary support force. The vertical component directly acts on the lowering or lifting of the bridge deck, while the horizontal component counteracts the lateral displacement tendency of the bridge deck caused by the vehicle, reducing additional frictional resistance. Compared to a vertical configuration where the driving force is entirely concentrated in the vertical direction (which is prone to lateral force due to slight tilting of the bridge deck, leading to shearing of the hydraulic cylinders), the inclined layout reduces the load on the drive unit through force decomposition. Especially when the bridge deck is carrying heavy loads, it reduces power loss and improves lifting efficiency.

[0034] When the sunken bridge plate carries a vehicle, it needs to withstand a large vertical load and horizontal impact force. The connection points between the bridge plate and the frame are distributed at an angle, which can transfer the load to the main body of the frame along the angle, avoiding excessive local stress caused by the load being concentrated at a single connection point when vertically installed. If a tilting cylinder is used for drive, the cylinder axis is closer to the force direction of the bridge plate, reducing the radial force on the cylinder (when vertically installed, the cylinder is prone to radial bending moment due to slight shaking of the bridge plate), and extending the service life of the drive components.

[0035] In use, the second set of sinking cylinders 120 is activated first to extend the piston rod, so that the bridge plate body 100 rotates and rises based on the hinge with the transport vehicle; after rising to the preset position, the vehicle can be driven in; after the vehicle has driven in, the piston rod can be retracted to sink the vehicle.

[0036] If the vehicle needs to be raised as a whole, first activate the second set of sinking cylinders 120 to extend the piston rod, allowing the bridge plate body 100 to rotate and rise based on its hinge with the transport vehicle. After rising to the preset position, activate the first set of sinking cylinders 110, allowing the bridge plate body 100 to rotate and rise to a position where both ends are level based on its hinge with the first set of sinking cylinders 110. When lowering is required, retract the first set of sinking cylinders 110 and the second set of sinking cylinders 120 in sequence to lower the vehicle. Please describe the contents of the above structure based on this principle, including detailed principles, effects, and operation.

[0037] Please see Figure 1 and Figure 2 The sunken bridge deck includes a bridge deck body 100, both ends of which are hinged to a transport vehicle via a first support 121 and a second support 122. A first set of sinking cylinders 110 and a second set of sinking cylinders 120 are provided on both sides of the bottom, each set containing a pair of cylinders 123. The cylinder body of cylinder 123 is hinged to the transport vehicle, and the piston rod is inclined upwards and hinged to the mounting beam at the bottom of the bridge deck body 100. The inclination direction forms a certain angle with the length direction of the bridge deck body 100, constituting a stable support and drive structure.

[0038] Its working principle is based on the force decomposition and alternating operation mechanism of the tilting cylinder 123. The tilted cylinder 123 decomposes the extension force into vertical and horizontal components. The vertical component is used to drive the bridge plate body 100 to rise or fall, while the horizontal component counteracts the lateral force when the vehicle enters or exits, preventing the bridge plate from swaying. When the two sets of cylinders work alternately, by means of the hinge point between the bridge plate body 100 and the transport vehicle, one set of cylinders drives one end of the bridge plate to rotate and rise, and then the other set of cylinders adjusts the other end, realizing the smooth lifting and attitude control of the entire bridge plate.

[0039] During operation, if a vehicle needs to drive in and sink, first activate the second set of sinking cylinders 120 to extend the piston rod, causing the bridge plate body 100 to rotate and rise to the preset position around the hinge point with the transport vehicle. After the vehicle drives in, retract the piston rod to allow the bridge plate to drive the vehicle to sink. To raise the vehicle as a whole to be level at both ends, first activate the second set of sinking cylinders 120 to raise one end of the bridge plate. After it reaches the position, activate the first set of sinking cylinders 110 to rotate and raise the other end of the bridge plate until both ends are level. When lowering, the operation is reversed, retracting the two sets of cylinders in sequence to gradually sink the bridge plate.

[0040] Furthermore, the force decomposition of the tilting cylinder 123 reduces stress concentration in a single direction. The horizontal component enhances the stability of the bridge deck, preventing lateral tilting when vehicles enter or exit, while the vertical component ensures efficient and labor-saving lifting and extends the service life of the drive components. The alternating operation mechanism allows the bridge deck to flexibly adapt to different height requirements, facilitating smooth vehicle entry and exit while precisely controlling the overall height to ensure compliance with height restrictions and axle load distribution during transportation, thereby improving loading efficiency and safety.

[0041] Further, please see Figure 1 The bridge deck body 100 includes a first longitudinal beam 131 and a second longitudinal beam 132 arranged at intervals, and a first crossbeam 134 and a second crossbeam 135 connecting the two ends of the first longitudinal beam 131 and the second longitudinal beam 132.

[0042] Furthermore, a number of continuous crossbeams 136 are provided at intervals between the first longitudinal beam 131 and the second longitudinal beam 132, and the continuous crossbeams 136 are connected to each other by continuous longitudinal beams 137; the top of the first longitudinal beam 131, the second longitudinal beam 132 and the number of continuous crossbeams 136 and continuous longitudinal beams 137 are covered with a tread plate 138.

[0043] Furthermore, a first mounting beam 141 and a second mounting beam 142 are provided between the first crossbeam 134 and the continuous crossbeam 136, and between the second crossbeam 135 and the continuous crossbeam 136; the bottom of the first mounting beam 141 and the second mounting beam 142 are respectively provided with a first set of hinge seats 143 and a second set of hinge seats 149 that are hinged to the first set of sinking oil cylinders 110 and the second set of sinking oil cylinders 120; the first set of hinge seats 143 and the second set of hinge seats 149 have the same structural configuration.

[0044] The aforementioned first longitudinal beam 131, second longitudinal beam 132, first crossbeam 134, and second crossbeam 135 constitute the basic frame of the bridge deck body 100. Continuous crossbeams 136 and continuous longitudinal beams 137 are distributed intermittently between them, forming a crisscrossing support structure. This design can evenly distribute the weight of the transported vehicles across the entire bridge deck, avoiding excessive local stress that could lead to deformation, and significantly improving the overall load-bearing capacity of the bridge deck. Even when transporting heavy engineering vehicles and other large vehicles, the structure can remain stable.

[0045] The first longitudinal beam 131, the second longitudinal beam 132, the continuous crossbeam 136, and the continuous longitudinal beam 137 are topped with a tread plate 138, forming a flat and continuous load-bearing surface. This not only provides stable support for vehicles going up and down the bridge deck, reducing friction damage between the tires and the bridge deck, but also prevents vehicles from skidding due to road bumps during transportation. At the same time, it protects the underlying longitudinal beams, crossbeams, and other structures from external impacts, extending the service life of the bridge deck.

[0046] Please see Figure 1 The first mounting beam 141 and the second mounting beam 142 connect the crossbeam to the continuous crossbeam 136. The first set of hinge seats 143 and the second set of hinge seats 149 at their bottoms provide stable connection points for the first set of lowering hydraulic cylinders 110 and the second set of lowering hydraulic cylinders 120. This layout allows the driving force of the hydraulic cylinders to be evenly transmitted to the bridge plate body 100 through the mounting beams, avoiding stress concentration in a certain area and ensuring smoother lifting and lowering of the bridge plate when the hydraulic cylinders operate alternately. Furthermore, the two sets of hinge seats have identical structures, facilitating installation and maintenance, ensuring the reliability of the connection between the hydraulic cylinders and the bridge plate, and providing a solid foundation for flexible height adjustment of the bridge plate.

[0047] Further, please see Figure 1 and Figure 3 The first set of sinking cylinders 110 and the second set of sinking cylinders 120 are respectively hinged to the transport vehicle through the third set of hinge seats 151 and the fourth set of hinge seats 152; the third set of hinge seats 151 and the fourth set of hinge seats 152 have the same structural configuration.

[0048] Furthermore, the third set of hinge seats 151 includes a reinforcing plate 144 connected to the transport vehicle, and a first hinge plate 145 and a second hinge plate 146 spaced apart on the reinforcing plate 144; the first hinge plate 145 and the second hinge plate 146 are also provided with hinge shafts 148.

[0049] Furthermore, the top of the first hinge plate 145 and the second hinge plate 146 is also provided with a pad plate 147 that can support the bridge plate body 100.

[0050] The first set of sinking cylinders 110 and the second set of sinking cylinders 120 are respectively hinged to the transport vehicle via the third set of hinge seats 151 and the fourth set of hinge seats 152, and the two sets have identical structures. This arrangement ensures the symmetry and consistency of the connection between the two sets of cylinders and the transport vehicle, making the cylinders bear force evenly and avoiding force deviations caused by differences in connection structures. This ensures coordinated movement at both ends when the bridge plate is raised and lowered, and the unified structure also reduces processing and maintenance costs. The reinforcing plate 144 of the first set of hinge seats 143 is connected to the transport vehicle, which can enhance the strength of the connection and prevent deformation of the transport vehicle connection due to long-term stress. The spaced first hinge plate 145 and second hinge plate 146, together with the hinge shaft 148, provide a stable hinge support point for the cylinders, allowing the cylinders to rotate flexibly during extension and retraction, ensuring effective force transmission. This structure is both stable and flexible, meeting the dynamic force requirements when the cylinders drive the bridge plate to rise and fall.

[0051] Please see Figure 1 The pads 147 on top of the first hinge plate 145 and the second hinge plate 146 can support the bridge plate when the bridge plate body 100 is raised or lowered to a specific position, avoiding direct hard contact between the bridge plate and the hinge plate, reducing collision wear, and extending the service life of both. At the same time, the pads 147 can distribute the pressure transmitted by the bridge plate, protect the hinge seat structure, ensure the stability of the bridge plate in the supporting state, and provide more reliable support for vehicle loading, unloading, and transportation.

[0052] Further, please see Figure 1 The first longitudinal beam 131 is also provided with a plurality of side hook units 160 at intervals; the side hook unit 160 includes a first side hook plate 161 and a second side hook plate 162 arranged at intervals, and a side hook body 163 disposed on the first side hook plate 161 and the second side hook plate 162.

[0053] During vehicle transportation, by passing a chain or belt through the side hook body 163, the vehicle can be effectively and securely connected to the transport vehicle, preventing displacement or slippage due to bumps or shaking during transport, thus improving the stability and safety of the vehicle during transportation. Side hook units 160 are spaced apart on the first longitudinal beam 131, allowing for flexible selection of appropriate hook positions to secure the vehicle according to its size and fixing requirements, enhancing the adaptability of the transport device to transport different types of vehicles. The first side hook plate 161 and the second side hook plate 162 cooperate to provide a stable mounting base for the side hook body 163, ensuring the structural stability of the side hook when bearing the vehicle fixing tension, and ensuring that the side hook can reliably play its role in fixing the vehicle throughout the transportation process. Furthermore, the design of the side hook body 163 also considers the ease of installing chains or belts, enabling operators to quickly and efficiently complete the vehicle fixing work, improving the efficiency of vehicle loading, unloading, and transportation.

[0054] Further, please see Figure 4 The pedal panel 138 is also provided with a wheel catcher 170 at one end; the wheel catcher 170 includes a fastening pin 171 and a first web plate 172 and a second web plate 173 disposed on both sides of the fastening pin 171; the first web plate 172 and the second web plate 173 are provided with wheel catcher panels 174. The wheel catcher panels 174 are provided with a concave arc surface to adapt to the car tire.

[0055] The recessed, curved wheel-stopping panel 174 is designed to closely conform to the outer contour of the car tire, greatly enhancing its tire-stopping effect. When the vehicle is parked on the pedal panel 138, the recessed curved surface acts like a "hug," firmly holding the tire in place and preventing it from rolling due to the vehicle's own inertia or external vibrations, further ensuring the vehicle's stability during transportation. The fastening pin 171 connects the first web plate 172 and the second web plate 173, providing a stable support for the entire wheel-stopping device 170 structure. This makes it less prone to deformation or damage when subjected to tire pressure and impact, ensuring the wheel-stopping device 170 functions reliably over a long period. Simultaneously, the reasonable spacing between the first web plate 172 and the second web plate 173 allows for the adaptation of various car tire widths, improving the versatility of the entire transportation device for different types of vehicles. Whether it's a small car or a large truck, the wheel-stopping device 170 can effectively secure the tire. This setup also enhances the safety of transportation operations, preventing accidents such as collisions and slips that may be caused by rolling vehicle tires, providing more reliable safety for operators, and reducing the risk of damage to vehicles and transportation equipment during transportation.

Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
