DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0022] References to "embodiments" herein mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments.

[0023] A beam transporter is a specialized engineering vehicle used to transport large precast concrete beams on railway and highway bridge construction sites. These bridge components are typically enormous, requiring multiple body components to be assembled to meet the transport requirements. Therefore, how to quickly and easily assemble beam transporters is a key challenge in transporting these large precast concrete beams.

[0024] In order to solve the above problems, the present application provides a vehicle body, referring to Figure 1 As shown, it includes a drive assembly 200, a plurality of body assemblies 100 and at least one connecting assembly 300, wherein the body assembly 100 is provided with a plurality of clamping portions 110; Figure 2 As shown, the drive assembly 200 includes a drive motor 210 and a screw rod 220. The drive motor 210 is connected to the screw rod 220, and the drive motor 210 is used to drive the screw rod 220 to rotate; Figure 3As shown, the connecting assembly 300 is disposed between adjacent body assemblies 100 and includes an extrusion block 310 and a plurality of clips 320. The clips 320 are spaced apart in a first direction X1. The extrusion block 310 is disposed between adjacent clips 320. In a second direction X2, the extrusion block 310 is connected to the screw 220. Rotation of the screw 220 causes the extrusion block 310 to move in the second direction X2. The clips 320 form an inclined force-bearing surface 321 in the first direction X1. The extrusion block 310 also forms an inclined pushing surface 311 in the first direction X1. The pushing surface 311 and the force-bearing surface 321 abut against each other. The extrusion block 310, through the cooperation of the pushing surface 311 and the force-bearing surface 321, moves the clips 320 toward or away from the clamping portion 110 in the first direction X1. The first direction X1 intersects with the second direction X2. This design makes the assembly of adjacent body assemblies 100 more flexible and convenient. The extrusion block 310 is driven to move in the second direction X2 by the screw rod 220. The inclined force-bearing surface 321 and the pushing surface 311 cooperate with each other to convert the displacement in the second direction X2 into the displacement in the first direction X1, so as to adjust the position of the clamping member 320 in the first direction X1, so that the clamping member 320 is close to or away from the clamping portion 110 in the first direction X1, thereby realizing the clamping and disengagement of the clamping member 320 from the clamping portion 110. This structure reduces the operational complexity of traditional mechanical connection methods and makes the assembly of the vehicle body more convenient. Due to the modular design, the vehicle body assembly 100 can be flexibly combined according to actual needs to meet the requirements of different transportation tasks. Compared with the fixed structure of traditional beam transport vehicles, this adjustable connection method significantly improves the versatility and operational convenience of the equipment and reduces maintenance costs.

[0025] In some embodiments, reference Figure 1 As shown, the vehicle body is assembled from multiple independent body assemblies 100, with the number of body assemblies 100 determined by the number of precast concrete beams. The connecting assembly 300 also includes a second housing 360. The drive motor 210 is mounted on the second housing 360 of the connecting assembly 300. The clamping member 320 and the extrusion block 310 are mounted within the second housing 360, encasing the clamping member 320 and the extrusion block 310 for protection.

[0026] Reference Figure 2 As shown, the screw rod 220 employs a reverse thread structure. The drive motor 210 drives the screw rod 220, thereby achieving the opposite movement of the extrusion block 310. The clamping members 320 in the connection assembly 300 are arranged in an array and can be spaced apart along the first direction X1 and the second direction X2. The specific number of clamping members 320 is determined by the connection strength of the body assembly 100.

[0027] In some embodiments, reference Figure 2As shown, the clamping members 320 are spaced apart in the first direction X1, and both ends of each clamping member 320 can be engaged with the clamping portion 110. If there are two clamping members 320 spaced apart in the first direction X1, each vehicle body assembly 100 has two clamping portions 110 in the first direction X1, both of which are engaged with the ends of the clamping members 320.

[0028] In some embodiments, reference Figure 3 As shown, the clamping portion 110 and the clamping member 320 can be connected using a wedge-shaped locking structure, a hydraulic lock pin, and a latch mechanism. The wedge-shaped locking structure involves configuring the end of the clamping member 320 and the clamping portion 110 of the body assembly 100 as wedge-shaped blocks, with the corresponding wedges cooperating to achieve connection. The hydraulic lock pin and latch mechanism involves providing a pin hole in the body assembly 100, inserting the clamping member 320 into the pin hole, and securing the connection via a latch. Other types of connection can also be used to achieve connection between the clamping portion 110 and the clamping member 320.

[0029] In the present application, refer to Figure 3 As shown, the clamping portion 110 is configured as a first wedge block 111, and the clamping member 320 includes a crossbeam 326 and a second wedge block 327. The second wedge block 327 is arranged at the end of the crossbeam 326. The first wedge block 111 and the second wedge block 327 are correspondingly arranged, and the first wedge block 111 and the second wedge block 327 are clamped to each other.

[0030] In some embodiments, the first direction X1 is the vertical direction of the vehicle body, the second direction X2 is the left-right direction of the vehicle body, and the third direction X3 is the front-to-back direction of the vehicle body. The front-to-back direction of the vehicle body is also the length direction of the vehicle body, and the left-to-right direction of the vehicle body is also the width direction of the vehicle body.

[0031] In some embodiments, reference Figure 4As shown, the extrusion block 310 has two pushing surfaces 311 in the first direction X1, and the distance between the two pushing surfaces 311 gradually increases from the outside to the inside in the second direction X2. Adjacent clamping members 320 in the first direction X1 each have a force-bearing surface 321, and the distance between the two force-bearing surfaces 321 gradually increases from the outside to the inside in the second direction X2. By gradually increasing the distance between the pushing surfaces 311 from the outside to the inside, the extrusion block 310 forms a trapezoidal structure. The distance between the force-bearing surfaces 321 gradually increases from the outside to the inside, forming a trapezoidal hole structure between adjacent force-bearing surfaces 321. When the extrusion block 310 moves outward in the second direction X2, the pushing surfaces 311 apply a thrust to the force-bearing surfaces 321, causing the distance between adjacent clamping members 320 to gradually increase and approach the clamping portion 110. When the extrusion block 310 moves inward in the second direction X2, due to the gradual decrease in the distance between the adjacent pushing surfaces 311, at least one clamping member 320 approaches the other clamping member 320 under the action of gravity, so that the distance between the adjacent clamping members 320 gradually decreases and moves away from the clamping portion 110. This technical feature can be implemented in a variety of ways. For example, the extrusion block 310 can be designed in a wedge shape or other tapered shapes, and the material can be selected from high-strength alloys or composite materials to ensure sufficient rigidity and durability. The force-bearing surface 321 of the clamping member 320 can adopt a similar design concept, and ensure that its distance change in the second direction X2 meets the requirements through precision processing. During implementation, computer-aided design technology can be used for modeling and verification to ensure the precise matching of the dimensions of each part.

[0032] In some embodiments, combined Figure 3 and Figure 4 As shown, when the extrusion blocks 310 move toward each other in the second direction X2, the force-bearing surface 321 and the pushing surface 311 slide relative to each other, causing the clamping member 320 to approach each other in the first direction X1 and move away from the clamping portion 110; when the extrusion blocks 310 move away from each other in the second direction X2, the force-bearing surface 321 and the pushing surface 311 slide relative to each other, causing the clamping member 320 to move away from each other in the first direction X1 and move closer to the clamping portion 110. This design allows the clamping member 320 to be flexibly loosened or fixed, improving the convenience of installation and maintenance. At the same time, when fixing is required, the clamping member 320 is close to the clamping portion 110, ensuring a stable connection. This structure not only improves operational flexibility but also ensures the reliability of the connection.

[0033] In some embodiments, the second direction X2 can be the width direction of the vehicle body or other specific direction. When the extrusion block 310 moves toward each other along this direction, the relative sliding between the force-bearing surface 321 and the pushing surface 311 causes the clamping member 320 to approach each other in the other direction (the first direction X1), thereby moving away from the clamping portion 110. This design allows the clamping member 320 to be loosened or adjusted in position, facilitating installation and removal. Conversely, when the extrusion block 310 moves in the opposite direction along the second direction X2, the sliding of the force-bearing surface 321 and the pushing surface 311 causes the clamping member 320 to disperse in the first direction X1 and approach the clamping portion 110, thereby connecting the two or enhancing the tightness of the connection between the two.

[0034] In some embodiments, reference Figure 2 As shown, at least one connecting assembly 300 includes a first connecting assembly 301 and a second connecting assembly 302 that are correspondingly arranged. The first connecting assembly 301 and the second connecting assembly 302 are spaced apart in the second direction X2. The extrusion block 310 of the first connecting assembly 301 and the extrusion block 310 of the second connecting assembly 302 are respectively connected to the screw 220 in the second direction X2. The screw 220 rotates to move the extrusion blocks 310 toward or away from each other in the second direction X2, respectively causing the clamping parts 320 of the first connecting assembly 301 and the clamping parts 320 of the second connecting assembly 302 to approach or move away from the corresponding clamping parts 110 in the first direction X1. The main beneficial effects of this technical solution are: first, by spaced apart in the second direction X2, the entire mechanical structure is made more stable and reliable. Second, the design of the extrusion block 310 moving when the screw 220 rotates ensures the accuracy and synchronization of the system during operation. Finally, the ability to adjust the clamping member 320 closer or farther in the first direction X1 provides greater flexibility and adaptability to meet different installation and usage requirements. This design not only improves the overall performance of the mechanical system, but also simplifies the installation process and effectively saves space.

[0035] In some embodiments, reference Figure 2 As shown, the first connecting assembly 301 and the second connecting assembly 302 are arranged along the second direction X2 and are spaced apart from each other. Each connecting assembly 300 is equipped with an extrusion block 310, which is respectively connected to the screw rod 220. When the screw rod 220 rotates, it drives the extrusion blocks 310 to move in the second direction X2, and this movement can be towards or in the opposite direction. Through this design, the clamping parts 320 on the first connecting assembly 301 and the second connecting assembly 302 can be adjusted in the first direction X1, so that they can be closer to or farther away from the corresponding clamping portion 110.

[0036] In some embodiments, reference Figure 2 As shown, the clip 320 includes a first clip 322, a second clip 323, a third clip 324, and a fourth clip 325, and the extrusion block 310 includes a first extrusion block 312 and a second extrusion block 313. The first clip 322, the second clip 323, and the first extrusion block 312 are configured as a first connecting assembly 301, while the third clip 324, the fourth clip 325, and the second extrusion block 313 are configured as a second connecting assembly 302. The first extrusion block 312 and the second extrusion block 313 are spaced apart in the second direction X2. The first extrusion block 312 is located between the first clip 322 and the second clip 323 in the first direction X1, and the second extrusion block 313 is located between the third clip 324 and the fourth clip 325 in the first direction X1. By rationally allocating the clip 320 and the extrusion block 310 into two independent connecting assemblies 300, the overall stability and durability of the vehicle body structure are enhanced. The first connecting assembly 301 and the second connecting assembly 302 are respectively responsible for different stress-bearing areas, avoiding stress concentration and improving safety. When the vehicle is impacted or vibrated, this layered arrangement can effectively absorb energy and reduce the possibility of structural deformation and damage.

[0037] In some embodiments, reference Figure 2 As shown, the vehicle body design includes multiple connection assemblies 300 to enhance structural stability. Four clips 320 and two extrusion blocks 310 work together to form a coordinated connection system. The first connection assembly 301 consists of a first clip 322, a second clip 323, and a first extrusion block 310 therebetween. The second connection assembly 302 consists of a third clip 324, a fourth clip 325, and a second extrusion block 310 therebetween. This configuration ensures that the vehicle body assembly 100 provides sufficient support in both the length (third direction X3), width (second direction X2), and height (first direction X1). In practice, the clips 320 can be made of high-strength, lightweight materials such as aluminum alloy or carbon fiber composite materials. The extrusion blocks 310 absorb and disperse stress from various directions and are typically made of metal with good plasticity and strength, heat-treated to enhance their load-bearing capacity.

[0038] In some embodiments, reference Figure 2As shown, the connecting assembly 300 also includes a first guide rod 330 and a second guide rod 340. The first guide rod 330 passes through the adjacent clamping member 320 in the first direction X1, and the second guide rod 340 passes through the extrusion block 310 in the second direction X2. This structure increases the stability of the connecting assembly 300 and improves the overall strength and durability of the vehicle body. The arrangement of the first guide rod 330 in the first direction X1 can guide the connecting member 410, while the design of the second guide rod 340 in the second direction X2 can guide and bear the weight of the extrusion block 310. Such a design not only improves the stability of the connecting assembly 300, but also improves the safety performance of the vehicle body. This design can be implemented using a variety of materials and installation methods. For example, the guide rod can be made of high-strength alloy and accurately matched with the clamping member 320 and the extrusion block 310 through precision processing.

[0039] In some embodiments, reference Figure 2 As shown, the connecting assembly 300 also includes an elastic member 350, which is sleeved on the first guide rod 330. On the one hand, when the clamping member 320 moves toward each other, by adding the elastic member 350 to the connecting assembly 300, a pulling force can be applied to the clamping member 320, causing the clamping member 320 to gradually separate from the clamping portion 110. Since the clamping member 320 and the clamping portion 110 may attract each other due to direct capillary force during long-term use, it is difficult for the clamping member 320 to separate from the clamping member 320 under the action of gravity. Therefore, the pulling force of the elastic member 350 can promote the separation of the two. On the other hand, the elastic member 350 sleeved on the first guide rod 330 can improve the buffering performance of the vehicle body connection part. This design can effectively absorb vibration energy during vehicle driving.

[0040] In some embodiments, reference Figure 2 As shown, the elastic member 350 is a component that can store and release energy. The elastic member 350 can be made of a spring, rubber, or other elastic material. The elastic member 350 is sleeved on the first guide rod 330. The elastic member 350 can be directly sleeved on the first guide rod 330 and positioned by an appropriate fixing device. Alternatively, the elastic member 350 can be combined with other components of the guide rod to form an integrated elastic system. In specific implementations, different specifications and types of elastic members 350 can be selected according to actual needs to adapt to different usage environments and requirements.

[0041] In some embodiments, reference Figure 5 As shown, the vehicle body assembly 100 includes a first shell 120, which forms a receiving cavity 121; the vehicle body further includes a reinforcement assembly 400, which is disposed in the receiving cavity 121. Figure 6As shown, the reinforcement assembly 400 includes multiple connectors 410 and multiple support frames 420. The multiple support frames 420 are spaced apart along a third direction X3. The multiple connectors 410 are located at least on opposite sides of the support frames 420. Each connector 410 is provided with multiple slots 411 along the third direction X3. The connectors 410 engage with the support frames 420 via the slots 411. The third direction X3, the second direction X2, and the first direction X1 are perpendicular to each other. By spacing the support frames 420 along the third direction X3, the pressure from different parts of the body assembly 100 can be effectively distributed, thereby improving the overall strength and rigidity of the body. The snap-fit connection between the connectors 410 and the support frames 420 via the slots 411 not only makes installation easier and faster, but also ensures a secure connection between the various components, further enhancing structural stability. This design also offers high adjustability and modularity. Because the connector 410 is provided with multiple slots 411 distributed along the third direction X3, different snap-fit positions can be selected according to actual needs, enabling flexible adjustment and optimization. In general, this body design not only improves structural strength and stability through reasonable space layout and efficient connection methods, but also simplifies the installation process and improves maintenance convenience.

[0042] In some embodiments, combined Figure 5 and Figure 6 As shown, the first housing 120 is the primary structural component of the vehicle body, forming an enclosed space, or chamber 121. This chamber 121 can accommodate various devices or components. A reinforcement assembly 400 is located within this chamber 121. This reinforcement assembly 400 increases the structural strength of the first housing 120 while also reducing the weight of the vehicle body assembly 100. The reinforcement assembly 400 consists of multiple connectors 410 and support frames 420. The support frames 420 are arranged along the third direction X3 and spaced apart at regular intervals. This design helps distribute force and enhance overall structural rigidity. The connectors 410 can be installed on opposite sides of the support frames 420, or on multiple sides. However, when only two connectors 410 are present, it is preferred that they be installed on opposite sides to enhance the structural stability of the reinforcement assembly 400 and ensure that the support frames 420 are securely attached. Each connector 410 is provided with multiple slots 411 distributed along the third direction X3. Through these slots 411 , the connector 410 can be quickly and reliably connected to the support frame 420 to form a stable connection structure.

[0043] In some embodiments, reference Figure 7As shown, the vehicle body also includes a composite component 500, which is positioned on the vehicle body component 100.
