Technical Field
[0001] This application relates to the field of cargo box trucks, and more particularly to a multi-purpose dump cargo box truck. Background Technology
[0002] A stake semi-trailer is a type of vehicle equipped with a cage-like or fence-like cargo box, with grilles installed at certain intervals inside the cage or fence, used for transporting goods. Stake semi-trailers are mainly used for transporting stake-type specialized cargo. Stake semi-trailers have the advantages of being lightweight and portable, and therefore also have a certain place in the field of cargo vehicles, mainly used for transporting agricultural and sideline products and other light goods.
[0003] With the development of the logistics industry, various goods need to circulate nationwide to achieve resource utilization upon arrival at their destinations. In recent years, promoting the standardization and digital transformation of logistics, optimizing transportation processes, improving operational efficiency, reducing logistics costs, and strengthening in-transit management have become common needs in logistics transportation. However, due to the limitations of cargo trucks, some goods cannot be transported, such as sand, gravel, and coal. These goods can only be transported by dump trucks. Dump trucks, due to their heavier size, are generally unsuitable for transporting ordinary light goods for cost and convenience reasons. Every type of vehicle has its limitations, and some models have to be taken out of service during industry downturns, not only wasting resources but also causing significant inconvenience to vehicle owners, leading to high maintenance costs and decreased income. Utility Model Content
[0004] In order to enable the cargo wagon to adapt to more types of goods and realize the self-unloading function, this application provides a multi-purpose self-unloading cargo wagon.
[0005] This application provides a multi-purpose self-unloading cargo truck, which adopts the following technical solution:
[0006] A multi-purpose self-dumping cargo truck includes a cab and a body, wherein the body includes a bottom support frame and a cargo box, the cargo box includes a frame and a floor, and the floor is liftable within the frame.
[0007] The bottom support frame includes a T-shaped main beam and a T-shaped tilting beam. The T-shaped tilting beam is fixedly installed on the vehicle floor. The T-shaped tilting beam can be switched between a support state and a tilting state. When the T-shaped tilting beam is in the support state, the T-shaped main beam supports the T-shaped tilting beam and the vehicle body, and the T-shaped tilting beam is located inside the T-shaped main beam.
[0008] By adopting the above technical solution, the adjustable floor design greatly improves the convenience of loading and unloading goods. Furthermore, the floor height can be adjusted according to the height requirements of different goods. When transporting taller goods, raising the floor prevents collisions between the goods and the top of the truck bed. When the T-shaped tilting beam is in the supported state, it works in conjunction with the T-shaped main beam to provide stable support for the truck bed. The T-shaped main beam supports both the T-shaped tilting beam and the truck bed. This double-layer support structure effectively distributes the weight of the truck bed and goods. Compared with the traditional single-beam structure, it can better cope with the impact of vehicle movement during operation. Various forces generated by road bumps, braking, and acceleration, such as vertical impact forces and horizontal inertial forces, ensure the safety of goods during transportation. The design of the T-shaped tilting beam located within the T-shaped main beam makes the bottom support frame structure more compact, without taking up extra space at the bottom of the carriage. It improves the strength of the vehicle body without increasing the vehicle height and enables the tilting function. When the T-shaped tilting beam is switched to the tilting state, it is convenient to unload the goods in the carriage. At the same time, this tilting state can also adapt to some special transportation scenarios or vehicle usage needs, improving the utilization rate of the vehicle.
[0009] Preferably, the T-shaped main beam includes a left main beam and a right main beam, the T-shaped flip beam includes a left flip beam and a right flip beam, and the bottom support frame also includes a bottom crossbeam and a flip crossbeam. The bottom crossbeam connects the left main beam and the right main beam, and the flip crossbeam connects the left flip beam and the right flip beam.
[0010] The flip beam includes a first beam and a second beam, with a gap between the first beam and the second beam, and the bottom beam can be embedded between the first beam and the second beam.
[0011] By adopting the above technical solution, the bottom crossbeam can be embedded in the gap between the first and second crossbeams, which is equivalent to forming a mortise and tenon structure. This structure can limit the relative displacement between the bottom crossbeam and the tilting crossbeam. When the vehicle is subjected to complex combinations of external forces, such as the superposition of centrifugal force during turning and road bumps, this structure can effectively prevent the twisting and deformation of the bottom support frame, thereby providing more reliable support for the carriage and cargo. Due to the design of the liftable floor, the structure of the bottom support frame can better cooperate with it. When the floor is raised or lowered, the connection between the bottom crossbeam and the tilting crossbeam can effectively adapt to this change.
[0012] Preferably, the flipping crossbeam and the bottom crossbeam are fitted together to form a composite crossbeam, and a left flipping shaft passes through the composite crossbeam near its left end; or
[0013] The composite beam is fitted with a right-flipping shaft near its right end.
[0014] By adopting the above technical solution, the setting of the left or right tilting shaft provides a precise rotation center for the tilting of the T-shaped tilting beam. When the T-shaped tilting beam needs to be switched to the tilting state, the carriage rotates around the tilting shaft, ensuring the stability and accuracy of the tilting process. The left or right tilting shaft is inserted near the end of the composite crossbeam. This structure allows the composite crossbeam to better transfer the force to the tilting shaft when it is subjected to external force, and then distribute it to other structural components of the vehicle through the tilting shaft. The composite crossbeam will transfer some of the impact force to other support structures of the frame through the tilting shaft, thereby reducing the risk of damage to local structures due to excessive force and enhancing the impact resistance of the entire bottom support frame.
[0015] Preferably, the composite beam has a left rotating shaft hole and a right rotating shaft hole near both ends, respectively. The left rotating shaft can be inserted into the left rotating shaft hole, and the right rotating shaft can be inserted into the right rotating shaft hole.
[0016] By adopting the above technical solution, the setting of the left and right pivot holes provides precise installation positions for the left and right tilting shafts. After the tilting shaft is inserted into the corresponding pivot hole, it can be ensured that it is in the predetermined and accurate spatial position, so that the T-shaped tilting beam always moves around the precisely fixed rotation center when it is tilting, avoiding the tilting shaft from deviating or shaking. In the vehicle assembly process, the installation method of inserting the left tilting shaft into the left pivot hole and the right tilting shaft into the right pivot hole is simple and direct. After the left tilting shaft is inserted into the left pivot hole, the carriage can tilt to the left, and after the right tilting shaft is inserted into the right pivot hole, the carriage can tilt to the right. When both the left and right tilting shafts are inserted, the carriage cannot tilt to the left or right.
[0017] Preferably, the flip beam is coaxial with the T-beam.
[0018] By adopting the above technical solution, when the tilting beam and the T-beam are coaxial, the force can be transmitted along a more direct and reasonable path when the vehicle is subjected to the weight of the cargo, the impact force of the road surface, or the inertial force during the driving process. This coaxial structure helps to improve the overall load-bearing capacity of the bottom support frame.
[0019] Preferably, the vehicle frame includes a frame body and a flip door, the flip door is mounted on the frame body, and the pivot of the flip door is located at the end of the frame body away from the wheel.
[0020] By adopting the above technical solution, due to the design of the door hinge position, the flip door can fit better against the main body of the frame when the door is closed, without taking up too much space inside the carriage. Compared with some side-opening doors or doors with a central hinge, it makes the interior space of the carriage more regular. When transporting goods with irregular shapes or large volumes, it can make fuller use of the carriage space and reduce space waste caused by the door structure.
[0021] Preferably, an automatic air pump door hook is provided between the vehicle frame body and the flip door.
[0022] By adopting the above technical solution, the automatic air pump door hook plays a reliable connecting role between the main body of the vehicle frame and the tilting door. When the door is closed, the automatic air pump door hook can generate a stronger locking force through the pressure provided by the air pump, effectively preventing the door hook from loosening due to long-term use, and enhancing the sealing of the compartment and the safety of the goods. When the automatic air pump door is opened, the pneumatic pump pushes out the rod through the linkage mechanism, and the door hook moves upward to realize the automatic unhooking action, which facilitates automatic unloading when the compartment is tilted. The automatic air pump door hook has the feature of automatic control, which improves the convenience of opening and closing the door. When loading and unloading goods, the driver or staff does not need to manually operate the complicated door hook device to open or close the door. Through simple control buttons or sensor triggers, the door hook can automatically complete the unlocking or locking action, reducing the steps and time of manual operation and improving the efficiency of loading and unloading goods.
[0023] Preferably, it also includes an integrated operating lever, which is mounted on the carriage and includes an operating lever, an operating lever mounting base, and an operating lever sliding control assembly;
[0024] The control lever is slidably mounted on the control lever mounting base via a control lever sliding control assembly. At least three control levers are provided, and each control lever can be controlled independently.
[0025] By adopting the above technical solution, the integrated control lever integrates multiple operating functions into one device. It is installed on the carriage for convenient use by operators. Operators do not need to search for different operating tools or devices around the carriage. They can complete multiple tasks through this control lever, improving the convenience of operation. Individual control allows each control lever to correspond to the same or different functions, improving work efficiency.
[0026] Preferably, the joystick sliding control assembly includes a joystick paddle disposed within the joystick mounting base, and a joystick sliding rod connected and installed with the joystick paddle.
[0027] By adopting the above technical solution, the control lever paddle is connected to the control lever slide rod and is set in the control lever fixing seat. This structure can achieve precise control of the control lever sliding. The operator can move the paddle and drive the control lever to slide on the fixing seat in a predetermined direction and trajectory by using the control lever slide rod. At the same time, with the linkage of the control lever paddle and slide rod, the control lever can perform a variety of different sliding actions, thereby realizing a variety of different functional operations.
[0028] Preferably, the operating lever fixing seat, the operating lever slide, and the paddle are in a clearance fit.
[0029] By adopting the above technical solution, the clearance fit allows the operating lever slide to move more smoothly within the operating lever mounting seat and during the linkage with the paddle.
[0030] In summary, this application includes at least one of the following beneficial technical effects:
[0031] 1. The adjustable floor design greatly improves the convenience of loading and unloading goods. Furthermore, the floor height can be adjusted according to the height requirements of different goods. When transporting taller goods, raising the floor prevents collisions between the goods and the top of the truck bed. When the T-shaped tilting beam is in the supported state, it works in conjunction with the T-shaped main beam to provide stable support for the truck bed. The T-shaped main beam supports both the T-shaped tilting beam and the truck bed. This double-layer support structure effectively distributes the weight of the truck bed and goods. Compared to the traditional single-beam structure, it can better cope with various forces generated during vehicle operation due to road bumps, braking, acceleration, etc., such as vertical impact forces and horizontal inertial forces, ensuring the safety of goods during transportation. The design of the T-shaped tilting beam located within the T-shaped main beam makes the bottom support frame structure more compact, without taking up extra space at the bottom of the truck bed. It increases the strength of the vehicle body without increasing the vehicle height and enables the tilting function. When the T-shaped tilting beam is switched to the tilting state, it facilitates unloading of goods from the truck bed. This tilting state can also adapt to some special transportation scenarios or vehicle usage needs, improving vehicle utilization.
[0032] 2. The bottom crossbeam can be embedded in the gap between the first and second crossbeams, forming a mortise and tenon structure that restricts the relative displacement between the bottom crossbeam and the tilting crossbeam. When the vehicle is subjected to complex combinations of external forces, such as the superposition of centrifugal force during turning and road bumps, this structure can effectively prevent the bottom support frame from twisting and deforming, thus providing more reliable support for the carriage and cargo. Due to the liftable design of the vehicle floor, the structure of the bottom support frame can better cooperate with it. When the carriage floor is raised or lowered, the connection between the bottom crossbeam and the tilting crossbeam can effectively adapt to this change. Attached Figure Description

[0038] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0039] This application discloses a multi-purpose dump truck. The multi-purpose dump truck includes a cab and a body, the body comprising a bottom support frame 1 and a cargo box 2. In an optional embodiment, the cargo box 2 includes a frame 21 and a floor 22, the floor 22 being height-adjustable within the frame 21. In a preferred embodiment, the distance between the floor 22 and the frame 21 is 20-30cm. When there is a gap between the floor 22 and the frame 21, the floor 22 can be raised and lowered independently, and can also be tilted to one side. In a preferred embodiment, the floor 22 is provided with a locking ring, and the frame 21 is provided with a locking hook that cooperates with the locking ring. When the floor 22 needs to be raised or tilted independently, the locking ring is in the open state; when the entire vehicle body needs to be tilted, the locking ring is in the locked state. Optionally, the vehicle floor 22 is lifted by a cylinder, and the cylinder of the vehicle floor 22 is equipped with a control component, so that the operator can control the vehicle floor 22 from the cab.
[0040] The bottom support frame 1 includes a T-beam 11 and a T-shaped tilting beam 12. The T-shaped tilting beam 12 is fixedly installed on the vehicle floor 22, and the T-beam 11 supports the T-shaped tilting beam 12 and the vehicle body 2. The T-shaped tilting beam 12 can be switched between a supported state and a tilting state. When the T-shaped tilting beam 12 is in the supported state, it is located inside the T-beam 11.
[0041] Optionally, when the T-shaped tilting beam 12 is in a supported state, it cooperates with the T-shaped main beam 11 to provide stable support for the carriage 2. The T-shaped main beam 11 supports the T-shaped tilting beam 12 and the carriage 2. This double-layer support structure can effectively distribute the weight of the carriage 2 and the cargo. Compared with the traditional single main beam structure, it can better cope with various forces generated by road bumps, braking, acceleration and other situations during vehicle operation, such as vertical impact force and horizontal inertial force, thereby reducing the possibility of deformation of the carriage 2 and ensuring the safety of the cargo during transportation.
[0042] Meanwhile, the design of the T-shaped tilting beam 12 located inside the T-shaped main beam 11 makes the structure of the bottom support frame 1 more compact and will not occupy additional space at the bottom of the carriage 2. When transporting some large goods, the placement of the goods will not be affected by the abrupt structure of the bottom support frame 1. For example, when transporting long and narrow goods (such as timber, pipes, etc.), the flat space at the bottom of the carriage 2 can be fully utilized to arrange the goods closely and increase the vehicle's load capacity.
[0043] In an optional embodiment, the T-beam 11 includes a left beam 111 and a right beam 112, the T-shaped tilting beam 12 includes a left tilting beam 121 and a right tilting beam 122, and the bottom support frame 1 further includes a bottom crossbeam 13 and a tilting crossbeam 14. The bottom crossbeam 13 connects the left beam 111 and the right beam 112, and the tilting crossbeam 14 connects the left tilting beam 121 and the right tilting beam 122. In an optional embodiment, both the tilting crossbeam 14 and the bottom crossbeam 13 are located in the middle, front, and rear of the frame. The middle section enhances the rigidity of the frame in the central area of the vehicle, preventing the frame from denting or deforming when bearing the weight of cargo or being impacted by the road surface; the front section helps to strengthen the structural stability of the front end of the frame; and the rear section supports the rear end of the cargo compartment 2 and bears the weight of the rear portion of the cargo. In a preferred embodiment, the bottom crossbeam 13 is provided with an interface for mounting suspension components.
[0044] Optionally, the tilting crossbeam 14 is coaxial with the T-beam 11. The tilting crossbeam 14 includes a first crossbeam 141 and a second crossbeam 142, with a gap between them. The bottom crossbeam 13 can be embedded between the first crossbeam 141 and the second crossbeam 142. This further enhances the overall structural integrity. When the bottom crossbeam 13 is embedded, it forms a mortise and tenon structure, restricting the relative displacement between the bottom crossbeam 13 and the tilting crossbeam 14. When the vehicle is subjected to complex combinations of external forces, such as the superposition of centrifugal force during turning and road bumps, it can effectively prevent the bottom from twisting and deforming, thus providing more reliable support for the carriage 2 and the cargo.
[0045] Furthermore, this structure better complements the design of the liftable floor 22. For example, when the floor 22 is raised or lowered, the connection between the bottom crossbeam 13 and the tilting crossbeam 14 can effectively adapt to changes. For instance, during the descent of the floor 2, the relative positions of the bottom crossbeam 13 and the tilting crossbeam 14 can be flexibly adjusted through gaps and embedded structures, without interference or affecting the stability of the structure due to changes in the position of the floor 2, thus improving the practicality of the vehicle during loading and unloading operations.
[0046] In an optional embodiment, the flip beam 14 and the bottom beam 13 are fitted together to form a composite beam, with a left flip shaft 15 passing through the composite beam near its left end; or a right flip shaft 16 passing through the composite beam near its right end. The setting of the left flip shaft 15 or the right flip shaft 16 provides a precise rotation center for the flipping of the T-shaped flip beam 12. When the T-shaped flip beam 12 needs to be switched to the flipped state, the carriage 2 rotates around the flip shaft, ensuring the stability and accuracy of the flipping process. The left flip shaft 15 or the right flip shaft 16 is located near the end of the composite beam. This structure allows the composite beam to better transfer the force to the flip shaft when subjected to external force, and then distribute it to other structural components of the vehicle through the flip shaft. The composite beam will transfer some of the impact force to other support structures of the frame through the flip shaft, thereby reducing the risk of damage to local structures due to excessive force and enhancing the impact resistance of the entire bottom support frame 1.
[0047] In a preferred embodiment, the composite crossbeam has left and right pivot holes near both ends, respectively. The left tilting shaft 15 can be inserted into the left pivot hole, and the right tilting shaft 16 can be inserted into the right pivot hole. The configuration of the left and right pivot holes provides precise installation positions for the left tilting shaft 15 and the right tilting shaft 16. After the tilting shaft is inserted into the corresponding pivot hole, it can be ensured that it is in a predetermined and accurate spatial position, so that the T-shaped tilting beam 12 always moves around a precisely fixed rotation center during the tilting operation, avoiding the tilting shaft from deviating or shaking. During vehicle assembly, the installation method of inserting the left tilting shaft 15 into the left pivot hole and the right tilting shaft 16 into the right pivot hole is simple and direct. After the left tilting shaft 15 is inserted into the left pivot hole, the carriage 2 can tilt to the left, and after the right tilting shaft 16 is inserted into the right pivot hole, the carriage 2 can tilt to the right. When both the left and right tilting shafts 15 and 16 are inserted, the carriage 2 cannot tilt to the left or right.
[0048] In a preferred embodiment, an integrated operating lever 3 is further included. The integrated operating lever 3 is mounted on the carriage 2. The integrated operating lever 3 includes an operating lever 31, an operating lever mounting base 32, and an operating lever sliding control assembly 33. The operating lever 31 is slidably mounted on the operating lever mounting base 32 via the operating lever sliding control assembly 33. At least three operating levers 31 are provided, and each operating lever 31 can be controlled independently. The integrated operating lever 3 integrates multiple operating functions into one device. Installed on the carriage 2, it is convenient for operators to use. Operators do not need to search for different operating tools or devices around the carriage 2. Multiple tasks can be completed through this single operating lever 31, improving operational convenience. Individual control allows each operating lever 31 to correspond to the same or different functions, improving work efficiency.
[0049] In an optional embodiment, the joystick sliding control assembly 33 includes a joystick paddle 331 disposed within the joystick mounting base 32, and a joystick sliding rod 332 connected and mounted to the joystick paddle 331. The joystick mounting base 32, the joystick sliding rod 332, and the paddle are in a clearance fit. This clearance fit allows the joystick sliding rod 332 to move more smoothly within the joystick mounting base 32 and during its linkage with the paddle. The joystick paddle 331, connected to and disposed within the joystick mounting base 32, enables precise control of the joystick 31's sliding motion. By moving the joystick paddle 331, the operator, with the aid of the joystick sliding rod 332, drives the joystick 31 to slide along a predetermined direction and trajectory on the mounting base 32. Simultaneously, the linkage between the joystick paddle 331 and the sliding rod allows the joystick 31 to perform various sliding actions, thereby corresponding to various functional operations.
[0050] In an optional embodiment, the vehicle frame 21 includes a frame body 211 and a flip door 212. The flip door 212 is mounted on the frame body, and the pivot of the flip door 212 is located at the end of the frame body away from the wheels. Due to the design of the door pivot position, when the door is closed, the flip door 212 can fit better against the frame body and will not occupy too much space inside the carriage 2. Compared with some side-opening doors or doors with a central pivot, it makes the interior space of the carriage 2 more regular. When transporting irregularly shaped or large-volume goods, it can make fuller use of the space in the carriage 2 and reduce space waste caused by the door structure.
[0051] Preferably, an automatic air pump door hook 213 is provided between the main frame body and the tilting door 212. The automatic air pump door hook 213 plays a reliable connection role between the main frame body and the tilting door 212. When the door is closed, the automatic air pump door hook 213 can generate a stronger locking force through the pressure provided by the air pump, effectively preventing the door hook from loosening due to long-term use, and enhancing the sealing of the compartment 2 and the safety of the goods. When the automatic air pump door is opened, the pneumatic pump pushes out the rod through the linkage mechanism, and the door hook moves upward to realize the automatic unhooking action, which facilitates automatic unloading when the compartment 2 is tilted. The automatic air pump door hook 213 has the feature of automatic control, which improves the convenience of opening and closing the door. When loading and unloading goods, the driver or staff does not need to manually operate the complicated door hook device to open or close the door. Through simple control buttons or sensor triggers, the door hook can automatically complete the unlocking or locking action, reducing the steps and time of manual operation and improving the efficiency of loading and unloading goods.
[0052] The implementation principle of this application embodiment is as follows: The liftable design of the vehicle floor 22 greatly improves the convenience of loading and unloading goods. Furthermore, the height of the vehicle floor 22 can be adjusted according to the height requirements of different goods. When transporting taller goods, raising the vehicle floor 22 can prevent the goods from colliding with the top of the carriage 2. When the T-shaped tilting beam 12 is in a supported state, it cooperates with the T-shaped main beam 11 to provide stable support for the carriage 2. The T-shaped main beam 11 supports the T-shaped tilting beam 12 and the carriage 2. This double-layer support structure can effectively distribute the weight of the carriage 2 and the goods. Compared with the traditional single-beam structure, it can better cope with the vehicle's movement. During operation, various forces generated by road bumps, braking, acceleration, etc., such as vertical impact force and horizontal inertial force, are mitigated to ensure the safety of goods during transportation. The design of the T-shaped tilting beam 12 located within the T-shaped main beam 11 makes the structure of the bottom support frame 1 more compact and does not occupy additional space at the bottom of the carriage 2. It improves the strength of the vehicle body without increasing the vehicle height and enables the tilting function. When the T-shaped tilting beam 12 is switched to the tilting state, it is convenient to unload the goods in the carriage 2. At the same time, this tilting state can also adapt to some special transportation scenarios or vehicle usage needs, improving the utilization rate of the vehicle.
[0053] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
