Description

Technical Field

[0001] The invention relates to the technical field of vehicle transportation machinery, in particular to a mobile boarding lifter used for vehicle loading and transportation. Background Art

[0002] In the field of vehicle loading and transportation, traditional loading methods often rely on simple ramps or fixed-height loading and unloading platforms. However, this method has many inconveniences and risks. For vehicles with different chassis heights, the fixed-height loading and unloading platform cannot be flexibly adjusted, which can easily cause vehicles to collide when entering and exiting, damaging the vehicle and cargo, increasing maintenance costs and transportation risks. Moreover, the slope loading method is not only inefficient, but also has high requirements for the flatness of the site. When used on uneven sites, the vehicle is prone to side sliding or tilting, seriously threatening the safety of the operator and the integrity of the cargo. In addition, the traditional loading method lacks effective vehicle positioning and stabilization devices. The vehicle is prone to displacement during the loading process, resulting in loading difficulties, extending the operation time, reducing the overall transportation efficiency, and it is difficult to meet the needs of modern logistics for fast, efficient and safe operation.

[0003] Although some existing lifters have certain height adjustment functions, they have defects in structural stability and precision control. For example, some simple hydraulic lifting devices are prone to shaking or tilting when carrying heavier vehicles due to unreasonable hydraulic system design, and cannot provide stable and reliable support for the vehicle, resulting in safety hazards during the lifting process of the vehicle. In the design of the loading unit, some existing equipment lacks accurate vehicle positioning and convenient loading operation design, and cannot adapt to the loading needs of various types of vehicles, resulting in a cumbersome and error-prone loading process. At the same time, the reliability of the conveying unit needs to be improved. Once a single conveying structure fails, the entire loading and transportation process will be forced to be interrupted, increasing downtime and maintenance costs, and seriously affecting the continuity and stability of logistics operations. These shortcomings limit the further development and application of vehicle loading and transportation equipment.

[0004] To this end, we proposed a mobile loading and unloading lift for vehicle loading and transportation. Summary of the invention

[0020] Compared with the prior art, it has the following beneficial effects:

[0021] 1. In the present invention, the height of the lifting frame can be flexibly adjusted according to actual conditions through the function of the lifting unit. At the same time, the loading unit and the positioning loading frame on the top work together with the lifting unit to achieve perfect coordination between height control and loading process. When loading a vehicle, the operator can accurately adjust the lifting frame to a position that matches the height of the vehicle chassis, and then use the positioning loading frame to accurately position the vehicle for loading, ensuring that the vehicle can smoothly enter the loading area, avoiding loading difficulties caused by inappropriate height, such as vehicle collision with the lifter, difficulty in loading and unloading of goods, etc., effectively reducing the difficulty of vehicle loading and improving the accuracy and safety of loading operations; during the loading process In the process, the vehicle needs to move smoothly from one position to the predetermined loading position. Any shaking or instability in this process may cause damage to the vehicle and cargo, and even endanger the safety of the operator. The close cooperation between the conveying unit and the loading unit can provide stable support and power transmission for the vehicle, so that the vehicle can always maintain a stable state during the entire loading and transportation process. Even in the face of some uneven loading sites or uneven distribution of the vehicle's center of gravity, it can effectively prevent the vehicle from deviating, skidding and other dangerous situations, greatly improving the safety and reliability of loading and transportation, providing a solid guarantee for the safe transportation of vehicles, and reducing potential economic losses and safety risks.

[0022] 2. The design of the lifting unit in the present invention fully considers space utilization and stability. The hydraulic support arm 1 and the hydraulic support arm 2 are rotatably arranged on the left and right sides of the mobile frame respectively. This symmetrical layout makes the force evenly distributed and provides a stable and reliable support foundation for the lifting frame. The cross-rotation connection mode of the front and rear sides and the setting of the rotation axis enhance the rigidity and stability of the entire structure, effectively preventing shaking or tilting during the lifting process. Even when carrying a heavy vehicle for lifting operations, it can ensure the smooth operation of the equipment and reduce the potential damage risk to the vehicle and the equipment itself due to structural instability. At the same time, the compact structural design is also convenient for installation and maintenance in the limited space of the mobile frame, thereby improving the integrity and practicality of the equipment. Through the hydraulic cylinder and The ingenious cooperation of the rotating connecting frame and the fixed frame realizes precise control of the lifting process. When the driving end of the hydraulic cylinder is extended, it can accurately drive the upper side of the hydraulic support arm 2 to lift upward. Due to the linkage relationship between the hydraulic support arm 1 and the hydraulic support arm 2, the two move synchronously, thereby lifting the lifting frame smoothly upward. This hydraulic drive method has high precision and controllability. The operator can accurately adjust the extension and retraction amount of the hydraulic cylinder through the hydraulic control system according to actual needs, thereby realizing fine adjustment of the overall height of vehicle loading and transportation. Whether it is docking vehicle cargo boxes of different heights or fine-tuning the height during loading and unloading to adapt to the placement of goods, it can be completed efficiently and accurately, greatly improving the operational convenience and efficiency of vehicle loading and transportation.

[0023] 3. In the present invention, the loading and transporting frame and the loading and transmission frame are provided with accurate moving tracks through the loading fixed frame and the transport limiting groove inside thereof, so that the two can adjust their positions quickly and smoothly during the loading process. The electrically controlled rotating shaft connects the loading and transmission frame and the loading and transporting frame, which is convenient for controlling the rotation angle of the loading and transporting frame, so that it can be tilted according to actual needs, which is convenient for the vehicle to drive into the positioning loading frame. Before the vehicle is loaded, the loading and transporting frame is first moved and tilted through a clever operation process, and the servo electric cylinder and the support block are used for stable support, so that the vehicle can enter the loading position with relatively low difficulty. The cooperation between the positioning loading frame and the loading and transporting frame ensures the accurate positioning and stable transportation of the vehicle during the loading process. The hydraulic telescopic block interacts with the positioning hole of the positioning loading frame, and can firmly fix the positioning loading frame when the vehicle is not loaded to ensure the accuracy of its position. When loading, the positioning loading frame can be conveniently released so that it can be smoothly towed to the loading surface. At the same time, the limiting slide The design of the block and the limit slide groove further enhances the stability during loading and prevents the vehicle from being displaced or shaken during transportation; finally, the meshing transmission of the transport drive sleeve with the transmission tooth grooves of the loading transmission frame and the loading transport frame realizes precise power transmission and ensures the stable sliding of the loading transport frame and the loading transmission frame in the transport limit groove, thereby ensuring that the vehicle can move smoothly in the loading unit, and the auxiliary chain, guide wheel, retractable shaft roller and related transmission structure, such as the linkage with the drive shaft through the bevel gear and the transmission chain, provide redundant protection for the conveying process. When the transport drive sleeve fails, the auxiliary chain can continue to provide traction and stability to prevent the vehicle from being in danger due to the failure of the conveying structure. This redundant design greatly improves the reliability and safety of the equipment during vehicle loading and transportation, reduces the downtime and potential safety accident risks caused by equipment failure, and provides strong support for long-term stable operation.

The two driving wheels 2 are controlled to rotate by the two reduction driving machines 4, and the mobile driving control of the entire mobile frame 1 is realized in cooperation with the two steering wheels 3, so as to facilitate the transportation and transfer of the loaded vehicles.

[0038] A lifting unit 5 is provided inside the mobile frame 1, and a lifting frame 6 is fixedly provided on the top of the lifting unit 5. Through the cooperation of the lifting unit 5 and the lifting frame 6, the height of the vehicle loading and transportation is flexibly controlled;

[0039] The loading unit 7 is provided on the top of the lifting frame 6, and a positioning loading frame 8 is movably provided on the top of the loading unit 7. By positioning the vehicle loading on the top of the positioning loading frame 8, the lifting unit 5 and the loading unit 7 are coordinated to realize the control of the vehicle loading and transportation height and the coordination during the loading and transportation process, thereby reducing the difficulty of vehicle loading;

[0040] A conveying unit 9 is provided at the bottom of the lifting frame 6, and the interior of the conveying unit 9 cooperates with the interior of the loading unit 7 for transmission; when the vehicle is loaded and transported, the cooperation of the conveying unit 9 and the loading unit 7 can ensure the stability of the vehicle loading and transportation to a great extent.

[0041] In a specific embodiment, the present invention can flexibly adjust the height of the lifting frame 6 according to actual conditions through the action of the lifting unit 5. At the same time, the loading unit 7 and the positioning loading frame 8 on the top thereof work in coordination with the lifting unit 5 to achieve perfect coordination between height control and the loading process. When loading a vehicle, the operator can accurately adjust the lifting frame 6 to a position that matches the height of the vehicle chassis, and then use the positioning loading frame 8 to accurately position the vehicle for loading, ensuring that the vehicle can smoothly enter the loading area, avoiding loading difficulties caused by inappropriate height, such as vehicle collision with the lifter, difficulty in loading and unloading of goods, etc., effectively reducing the difficulty of vehicle loading and improving the accuracy and safety of loading operations. During the loading process, the vehicle needs to move smoothly from one position to the predetermined loading position. Any shaking or instability during this process may cause damage to the vehicle and the cargo, and even endanger the safety of the operator. The close cooperation between the conveying unit 9 and the loading unit 7 can provide stable support and power transmission for the vehicle, so that the vehicle can always maintain a stable state during the entire loading and transportation process. Even when facing some uneven loading sites or uneven distribution of the center of gravity of the vehicle, it can effectively prevent the vehicle from deviating, skidding and other dangerous situations, greatly improving the safety and reliability of loading and transportation, providing a solid guarantee for the safe transportation of vehicles, and reducing potential economic losses and safety risks.

[0042] Specifically, the lifting unit 5 includes a hydraulic support arm 10, a hydraulic support arm 2 11 and a hydraulic cylinder 14. The left and right sides of the mobile frame 1 are rotatably provided with the hydraulic support arm 10 and the hydraulic support arm 2 11, and the tops of the hydraulic support arm 10 and the hydraulic support arm 2 11 are rotatably connected to the two sides of the bottom of the lifting frame 6, respectively. The front and rear sides of the hydraulic support arm 10 and the hydraulic support arm 2 11 are cross-rotatably connected, and a rotating shaft 12 is rotatably provided between the front and rear sides of the hydraulic support arm 10 and the hydraulic support arm 2 11. A rotating connecting frame 13 is fixedly provided in the middle of the hydraulic support arm 2 11, and a fixed frame 16 is fixedly provided at the bottom of the hydraulic support arm 10. A hydraulic cylinder 14 is rotatably provided on one side of the fixed frame 16, and the driving end of the hydraulic cylinder 14 is rotatably connected to the top of the rotating connecting frame 13. A hydraulic control system 15 is also fixedly provided on one side of the mobile frame 1, and the interior of the hydraulic control system 15 is hydraulically connected to the interior of the hydraulic cylinder 14.

[0043] It should be noted that when controlling the lifting and lowering of the vehicle loading and transportation, the driving end of the hydraulic cylinder 14 is extended, and the driving end of the hydraulic cylinder 14 is used to drive the upper side of the hydraulic support arm 2 11 to lift upward through the rotating connecting frame 13. At the same time, since the hydraulic support arm 10 and the hydraulic support arm 2 11 are rotatably connected through the rotating shaft 12, as the upper side of the hydraulic support arm 2 11 is lifted upward, the upper side of the hydraulic support arm 10 will also be lifted synchronously with the hydraulic support arm 2 11, and the tops of the hydraulic support arm 10 and the hydraulic support arm 2 11 are connected to the two sides of the bottom of the lifting frame 6, so that the hydraulic support arm 10 and the hydraulic support arm 2 11 drive the lifting frame 6 to lift upward, thereby completing the lifting and lowering control of the overall height of the vehicle loading and transportation.

[0044] In a specific embodiment, the design of the lifting unit 5 in the present invention fully considers space utilization and stability. The hydraulic support arm 10 and the hydraulic support arm 2 11 are rotatably arranged on the left and right sides of the mobile frame 1 respectively. This symmetrical layout makes the force evenly distributed, and provides a stable and reliable support foundation for the lifting frame 6. The cross-rotation connection mode of the front and rear sides and the setting of the rotating shaft 12 enhance the rigidity and stability of the entire structure, effectively preventing shaking or tilting during the lifting process. Even when carrying a heavy vehicle for lifting operations, it can ensure the smooth operation of the equipment and reduce the potential damage risk to the vehicle and the equipment itself due to structural instability. At the same time, the compact structural design is also convenient for installation and maintenance in the limited space of the mobile frame 1, which improves the integrity and practicality of the equipment; through the hydraulic cylinder 1 4 is cleverly coordinated with the rotating connecting frame 13 and the fixed frame 16 to achieve precise control of the lifting process. When the driving end of the hydraulic cylinder 14 is extended, it can accurately drive the upper side of the hydraulic support arm 2 11 to lift upward. Due to the linkage relationship between the hydraulic support arm 10 and the hydraulic support arm 2 11, the two act synchronously, thereby smoothly lifting the lifting frame 6 upward. This hydraulic drive method has high precision and controllability. The operator can accurately adjust the extension and contraction amount of the hydraulic cylinder 14 through the hydraulic control system 15 according to actual needs, thereby achieving fine adjustment of the overall height of vehicle loading and transportation. Whether it is docking vehicle cargo boxes of different heights or fine-tuning the height during loading and unloading to adapt to the placement of goods, it can be completed efficiently and accurately, greatly improving the operational convenience and efficiency of vehicle loading and transportation.

[0045] Embodiment 2:

[0046] Specifically, the loading unit 7 includes a loading fixed frame 17, a loading transport frame 18 and a loading transmission frame 19.

When the vehicle is loaded and transported from the top of the loading and transport frame 18, the two positioning grooves on one side of the positioning loading frame 8 are connected by the traction equipment of the loading surface. At this time, the four hydraulic telescopic blocks 21 are controlled to withdraw from the positioning holes inside the positioning loading frame 8, and the traction equipment is used to pull the positioning loading frame 8 from the top of the loading and transport frame 18 to the loading surface. Through the cooperation of the two limiting sliders and the two limiting slide grooves, the stability of vehicle loading can be guaranteed to a great extent.

[0047] Furthermore, two servo electric cylinders 22 are fixedly disposed on one side of the bottom of the loading and transporting frame 18 , and support blocks 23 are fixedly disposed on the driving ends of the two servo electric cylinders 22 .

[0048] It should be noted that when the vehicle is loaded and transported, first, the loading and transporting frame 18 and the loading and driving frame 19 are controlled to move in the transport limiting groove 20 inside the loading and fixed frame 17 toward the side of the vehicle to be loaded and transported, and then the electric rotating shaft arranged on one side of the loading and driving frame 19 is used to control one side of the loading and transporting frame 18 to rotate toward the ground. After the servo electric cylinder 22 and the support block 23 on one side of the bottom of the loading and transporting frame 18 slide to one side of the loading and fixed frame 17, the driving end of the servo electric cylinder 22 extends, and the support block 23 is used to contact the ground to support the bottom of one side of the loading and transporting frame 18. As one side of the loading and transporting frame 18 rotates, the servo electric cylinder 22 is controlled to rotate toward the ground. The driving end of the servo electric cylinder 22 is synchronously reset, so that the loading and transporting frame 18 is in an inclined state when loading the vehicle. At this time, one side of the loading and transporting frame 18 is in contact with the ground, and the other side is located on one side of the loading transmission frame 19. After the vehicle to be loaded is loaded on the top of the positioning loading frame 8 through the fixed lock, the driving ends of the two servo electric cylinders 22 are controlled to extend to lift the height of one side of the loading and transporting frame 18 until the upper end surface of the loading and transporting frame 18 and the upper end surface of the loading transmission frame 19 are in a horizontal state. Finally, the conveying unit 9 is cooperated to load the vehicle on the top of the positioning loading frame 8 to the top of the loading fixed frame 17 to complete the loading operation of the vehicle.

The front and rear sides of the loading fixed frame 17 are both rotatably provided with a transmission frame 24, and the interiors of the two transmission frames 24 are both driven by rotating a plurality of transmission shafts 37 rotatably provided inside the loading fixed frame 17. The surfaces of the two transmission frames 24 are also provided with a transport drive gear sleeve 25 through a connecting piece fixed sleeve, and one side of the two transport drive gear sleeves 25 extends to the inside of the two transport limit grooves 20 respectively. The loading transmission frame 19 and the loading transport frame 18 are both provided with a transmission tooth groove 26 below the front and rear sides, and the tooth surface of the transmission tooth groove 26 and the tooth surface of the transport drive gear sleeve 25 are meshed for transmission.

[0050] Furthermore, a servo motor 31 is fixedly provided on one side of the bottom of the lifting frame 6, and a driving shaft 32 is fixedly provided on the top end of the output shaft of the servo motor 31 through a coupling, and a transmission chain 1 33 is meshed and transmitted at the top end of the driving shaft 32, and the front side of the transmission chain 1 33 is meshed and transmitted with one of the transmission shafts 2 37 rotatably arranged on the front side of the loading fixed frame 17, and the rear side of the transmission chain 1 33 is meshed and transmitted with a driven shaft arranged on the rear side of the loading fixed frame 17, and at the same time, the bottom end of the driven shaft and one of the transmission shafts 2 37 arranged on the rear side of the loading fixed frame 17 are transmitted by means of two gear external meshing; this arrangement is intended to ensure that the two transmission frames 24 on the front and rear sides of the loading fixed frame 17 rotate in opposite directions, so as to synchronously control the sliding of the loading transport frame 18 and the loading transmission frame 19 in the transport limit groove 20.

[0051] Furthermore, an auxiliary chain 27 is sleeved on one side of the loading transmission frame 19, and a guide wheel 28 is fixedly arranged on one side of the loading fixed frame 17, and one end of the auxiliary chain 27 is drivingly connected to the surface of the guide wheel 28, and a mounting frame 30 is fixedly arranged on one side of the bottom of the loading fixed frame 17, and a retractable shaft roller 29 is rotatably arranged inside the mounting frame 30, and the surface of the retractable shaft roller 29 is fixedly connected to one end of the auxiliary chain 27, and the retracting and releasing control of the auxiliary chain 27 is realized by controlling the clockwise and counterclockwise rotation of the retractable shaft roller 29;

[0052] Furthermore, a transmission shaft 35 is rotatably provided inside the lifting frame 6 through the mounting block, and a bevel gear 34 is fixedly provided at one end of the transmission shaft 35 and the bottom end of the driving shaft 32, and the tooth surfaces of the two bevel gears 34 are meshed for transmission, and a transmission chain 2 36 is also meshed for transmission at the other end of the transmission shaft 35, and one end of the transmission chain 2 36 extends to the inside of the mounting frame 30, and one end of the transmission chain 2 36 is meshed for transmission connection with one end of the retracting shaft roller 29.

[0053] It should be noted that when loading the vehicle, the transmission chain 33 set at one end of the driving shaft 32 drives the two transmission frames 24 on the front and rear sides to rotate, and the transport driving gear sleeve 25 cooperates with the meshing transmission of the transmission tooth groove 26 to allow the loading transport frame 18 and the loading transmission frame 19 to slide to one side inside the transport limit groove 20. At the same time, the surface of the retractable shaft roller 29 controls the winding of the auxiliary chain 27, and one end of the auxiliary chain 27 is used to further ensure the stability of the loading transport frame 18 during the sliding process inside the transport limit groove 20. Through the coordinated work of the two conveying structures of the transport driving gear sleeve 25 and the auxiliary chain 27, when one side fails, the traction of the other side can be stable, thereby avoiding safety accidents caused by the failure of one conveying structure during vehicle loading and transportation.

[0054] In a specific embodiment, the present invention provides a precise moving track for the loading and transporting frame 18 and the loading and driving frame 19 through the loading fixed frame 17 and the transport limiting groove 20 inside the loading and transporting frame 18, so that the two can adjust their positions quickly and smoothly during the loading process. The electrically controlled rotating shaft connects the loading and driving frame 19 and the loading and transporting frame 18, which is convenient for controlling the rotation angle of the loading and transporting frame 18, so that it can be tilted according to actual needs, which is convenient for the vehicle to enter the positioning loading and transporting frame 8. Before the vehicle is loaded, through a clever operation process, the loading and transporting frame 18 is first moved and tilted, and the servo electric cylinder 22 and the support block 23 are used for stable support, so that the vehicle can enter the loading position with lower difficulty; the cooperation between the positioning loading frame 8 and the loading and transporting frame 18 ensures the precise positioning and stable transportation of the vehicle during the loading process, and the hydraulic telescopic block 21 interacts with the positioning hole of the positioning loading frame 8, so that the positioning loading frame 8 can be firmly fixed when the vehicle is not loaded to ensure the accuracy of its position, and when loading, the positioning loading frame 8 can be easily released so that it can be smoothly towed to the loading surface. At the same time, The design of the limit slider and the limit slide groove further enhances the stability during loading and prevents the vehicle from being displaced or shaken during transportation. Finally, the meshing transmission of the transport drive gear sleeve 25 with the transmission tooth grooves 26 of the loading transmission frame 19 and the loading transport frame 18 realizes precise power transmission and ensures the stable sliding of the loading transport frame 18 and the loading transmission frame 19 in the transport limit groove 20, thereby ensuring that the vehicle can move smoothly in the loading unit 7. The auxiliary chain 27, guide wheel 28, retractable shaft roller 29 and related transmission structures, such as the linkage with the drive shaft 32 realized by the bevel gear 34 and the transmission chain 2 36, provide redundant protection for the conveying process. When the transport drive gear sleeve 25 fails, the auxiliary chain 27 can continue to provide traction and stability to prevent the vehicle from being in danger due to a failure of the conveying structure. This redundant design greatly improves the reliability and safety of the equipment during vehicle loading and transportation, reduces downtime and potential safety accident risks caused by equipment failure, and provides strong support for long-term stable operations.

[0055] In summary, the bottom of the mobile frame 1 in the present invention drives the driving wheel 2 to rotate through the reduction drive machine 4, and cooperates with the steering wheel 3 to achieve overall flexible movement, which is convenient for transporting and transferring the loaded vehicle; in the lifting unit 5, the hydraulic cylinder 14 drives the hydraulic support arm 10 and the hydraulic support arm 2 11 to synchronously lift the lifting frame 6, which can accurately control the height of vehicle loading and transportation, and adapt to the needs of different vehicles and loading scenarios; the loading fixed frame 17, the loading transport frame 18 and the loading transmission frame 19 of the loading unit 7 cooperate with each other, and the loading transport frame 18 can be tilted to facilitate vehicle loading, and the servo electric cylinder 22 and the support block 23 at the bottom thereof ensure The stability of the loading process is improved. At the same time, the design of the hydraulic telescopic block 21 and the positioning loading frame 8 improves the positioning accuracy and stability of vehicle loading; in the conveying unit 9, the transport drive gear sleeve 25 and the auxiliary chain 27 work together. The transport drive gear sleeve 25 controls the sliding of the loading transport frame 18 and the loading transmission frame 19 through the meshing transmission with the transmission tooth groove 26, and the auxiliary chain 27 further ensures the stability of the sliding process. Even if one side fails, the other side can maintain traction stability, effectively avoiding vehicle loading and transportation safety accidents caused by conveying structure failures, and greatly improving the efficiency, stability and safety of vehicle loading and transportation.

[0056] Embodiment 3:

[0057] Specifically, this embodiment also discloses a working method of a mobile vehicle loading and transporting lift, as follows:

[0058] When the vehicle needs to be loaded and transported, the moving function of the mobile rack 1 is first used to start the two reduction drive machines 4 on the front and rear sides of the mobile rack 1 to drive the two driving wheels 2 on one side of the bottom to rotate, and at the same time cooperate with the two steering wheels 3 on the other side. The operator can flexibly control the mobile rack 1 to move to the appropriate position of the vehicle to be loaded according to the actual site and vehicle position, so as to achieve overall rapid transfer and precise positioning, and prepare for subsequent loading operations;

[0059] Then, the preparation work before loading is carried out. In the loading unit 7, the loading and transporting frame 18 and the loading and driving frame 19 are controlled to move in the transport limiting groove 20 inside the loading and fixed frame 17 toward the side of the vehicle to be loaded and transported. After reaching the appropriate position, the electric rotating shaft on one side of the loading and driving frame 19 is used to rotate one side of the loading and transporting frame 18 toward the ground. In this process, the servo electric cylinder 22 and the support block 23 on one side of the bottom of the loading and transporting frame 18 slide with the rotation of the loading and transporting frame 18. After sliding to one side of the loading and fixed frame 17, the driving end of the servo electric cylinder 22 extends, and the support block 23 contacts the ground, providing bottom support for one side of the loading and transporting frame 18. At the same time, as the loading and transporting frame 18 continues to rotate, the driving end of the servo electric cylinder 22 is controlled to be reset synchronously, so that the loading and transporting frame 18 is in an inclined state. At this time, one side of it contacts the ground, and the other side is located on one side of the loading and driving frame 19, which is convenient for vehicles to enter.

[0060] Then, the vehicle loading operation begins. The vehicle to be loaded is loaded on the top of the positioning loading rack 8 through the fixed lock. At this time, the positioning loading rack 8 cooperates with the limiting slide grooves on the top of the loading and transporting rack 18 and the loading transmission rack 19 through the limiting slider at the bottom thereof to ensure stability during the loading process. At the same time, the hydraulic telescopic blocks 21 around the top of the loading and transporting rack 18 are inserted into the positioning holes around the inside of the positioning loading rack 8 to firmly fix the position of the positioning loading rack 8. After that, the driving ends of the two servo electric cylinders 22 are controlled to extend again, so that the height of one side of the loading and transporting rack 18 is gradually raised until the upper end surface of the loading and transporting rack 18 and the upper end surface of the loading transmission rack 19 are in a horizontal state, and the vehicle is ready to be transported to the top of the loading fixed rack 17;

[0061] During the vehicle loading and transportation process, the servo motor 31 on the bottom side of the lifting frame 6 is started, and the top end of its output shaft drives the driving shaft 32 to rotate through the coupling, and the transmission chain 1 33 at the top end of the driving shaft 32 drives the two transmission frames 24 on the front and rear sides of the loading fixed frame 17 to rotate. This is achieved by the meshing transmission of the transmission chain 1 33 and a transmission shaft 2 37 on the front side of the loading fixed frame 17 and the driven shaft on the rear side. At the same time, the bottom end of the rear driven shaft and the other transmission shaft 2 37 are meshed with two gears to ensure that the two transmission frames 24 rotate in opposite directions, so that the transportation drive gear sleeves 25 on the surfaces of the two transmission frames 24 are meshed with the transmission tooth grooves 26 on the front and rear sides of the loading transmission frame 19 and the loading and transport frame 18, thereby driving the loading and transport frame 18 and the loading transmission frame 19 to move inside the transportation limit groove 20 toward the loading fixed frame The bottom end of the driving shaft 32 is meshed with the helical gear at one end of the transmission shaft 1 35 through the helical gear 34, and the transmission chain 2 36 at the other end of the transmission shaft 1 35 drives the retracting shaft roller 29 inside the mounting frame 30 to rotate. By controlling the clockwise or counterclockwise rotation of the retracting shaft roller 29, the retracting and releasing control of the auxiliary chain 27 is realized. One end of the auxiliary chain 27 is sleeved and connected with one side of the loading transmission frame 19, and the other end is fixedly connected to the surface of the retracting shaft roller 29 through the transmission connection of the guide wheel 28, thereby further ensuring the stability of the loading and transporting frame 18 in the process of sliding inside the transport limit groove 20. Through the coordinated work of the two conveying structures of the transport driving gear sleeve 25 and the auxiliary chain 27, it is ensured that the vehicle can smoothly move from the loading and transporting frame 18 and the loading transmission frame 19 to the top of the loading fixed frame 17, thereby completing the loading operation of the vehicle.

[0062] If the height of the vehicle loading and transportation needs to be adjusted during the loading and transportation process, such as docking vehicle cargo boxes of different heights or fine-tuning the height according to the cargo placement requirements during loading and unloading, it can be achieved through the lifting unit 5. The operator accurately adjusts the extension and contraction amount of the hydraulic cylinder 14 through the hydraulic control system 15. When the driving end of the hydraulic cylinder 14 extends, the upper side of the hydraulic support arm 2 11 will be driven to lift upward through the rotating connecting frame 13. Since the front and rear sides of the hydraulic support arm 10 and the hydraulic support arm 2 11 are cross-rotated and connected by the rotating shaft 12, and the tops of the two are respectively connected to the two sides of the bottom of the lifting frame 6, the upper side of the hydraulic support arm 10 will be synchronously lifted with the hydraulic support arm 2 11, thereby driving the lifting frame 6 to lift upward, thereby achieving fine adjustment of the overall height of the vehicle loading and transportation, ensuring the height adaptability and operational convenience of the vehicle during the entire loading and transportation process.
