Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of flatbed trucks, and particularly relates to a heavy full-remote-control electric-drive flatbed transfer vehicle. BACKGROUND

[0002] As a kind of transport equipment specially used for carrying heavy materials, the flatbed transfer vehicle is widely used in manufacturing industry, logistics transportation and engineering construction due to its large load capacity, flexible operation and strong adaptability. Especially in the operation scene of loading and long-distance transfer of equipment in cooperation with trucks, the collaborative operation capability of the flatbed transfer vehicle is particularly critical. However, in the actual use process, the difference in height and posture between the transfer vehicle and the truck is always one of the technical bottlenecks that are difficult to solve, especially in the case of complex terrain, variable load and different heights of truck platforms, the posture adjustment of the transfer vehicle is often not in place, which often causes poor docking of goods and seriously affects the efficiency and safety of the carrying operation.

[0003] At present, the common flatbed transfer vehicle relies on manual judgment and mechanical devices to complete the operation in terms of height and posture adjustment, which not only has the problems of low adjustment accuracy and slow response speed, but also easily causes misalignment of the transfer vehicle chassis and the truck platform due to improper adjustment, causing safety hazards such as material falling, equipment damage and operation interruption. Especially when the truck travels to different unloading areas and is parked on uneven ground, the transfer vehicle needs to frequently adjust the height to match different platforms, which puts higher requirements on the instant adjustment capability and posture stability of the equipment. When facing the demand of rapid docking and multiple lifting, the traditional adjustment system often fails to meet the requirements, which not only reduces the overall work efficiency, but also increases the labor intensity of the operators. With the continuous improvement of transportation automation level, it has become a technical problem to be solved in the industry to realize efficient and accurate docking between the transfer vehicle and the truck.

[0009] As a preferred technical scheme of the present application, the top of the swing spoon is inserted with a butt spring and is connected with the longitudinal beam in a penetrating manner, and a damping spring is arranged around the swing spoon to limit displacement of the swing spoon.

[0010] As a preferred technical scheme of the present application, wheel cavities are symmetrically arranged at two sides of the cross rod, and are matched with the outer periphery of the hollow wheel to prevent deviation and positioning of the wheel set.

[0011] As a preferred technical scheme of the present application, rubber pads are respectively arranged in the middle part of the longitudinal beam, and the rubber pads are elastically abutted on the compartment plate to elastically overcorrect the posture of the transfer trolley.

[0012] As a preferred technical scheme of the present application, a surrounding fence is arranged around the outer periphery of the compartment plate to prevent goods from sliding off.

[0013] As a preferred technical scheme of the present application, hinge support points and middle support points are symmetrically arranged at the edges of the bottom wall of the compartment plate, middle support points are arranged at the centers of the four corners of the compartment plate to quickly respond to the posture adjustment of the transfer trolley.

[0014] As a preferred technical scheme of the present application, the wheel set can be matched with a T-shaped track to transfer stored goods.

[0015] As a preferred technical scheme of the present application, a battery pack is arranged in the longitudinal beam.

[0016] The present application has the following beneficial effects: Structure stability guarantees load bearing and safety: The heavy full-remote control electric drive flat transfer vehicle adopts H-shaped main frame structure, which is composed of symmetrical longitudinal beams and crossbars connecting the longitudinal beams. From the perspective of mechanics, the symmetrical longitudinal beam design can evenly distribute the weight of the loaded goods, making the force on each part of the main frame balanced. The crossbar further enhances the overall rigidity of the main frame, connecting the longitudinal beams into a stable whole. This structural design enables the transfer vehicle to effectively avoid structural deformation and damage caused by excessive local stress when carrying heavy goods, greatly improving the load capacity and safety of the transfer vehicle.

[0017] Wheel set and transmission mechanism ensure flexible operation: The wheel set and transmission mechanism are coupled and connected through the transmission frame and the main frame, which is the core of the flexible operation of the transfer vehicle. The transmission frame is arranged across the crossbar, which reasonably arranges the position of the wheel set. When the power is transmitted to the wheel set through the transmission mechanism, the wheel set can rotate flexibly to realize the forward and backward movement of the transfer vehicle. In different working scenarios, whether it is a spacious site or a narrow passage, this design can make the transfer vehicle easily cope with it. For example, when working in a narrow warehouse, the transfer vehicle can flexibly shuttle under the goods shelves and efficiently complete the transfer task of goods.

[0018] Homodyne assembly realizes precise attitude adjustment: The second homodyne mechanism in the homodyne assembly includes a horizontal oil cylinder and a vertical oil cylinder, which are connected with the compartment plate and can realize the lifting adjustment of the compartment plate. In actual transportation process, the uneven distribution of goods and the complex transfer road conditions will affect the attitude of the transfer vehicle. At this time, the horizontal oil cylinder and the vertical oil cylinder can be adjusted according to the specific situation. When the center of gravity of the goods deviates to one side, the oil cylinder on the corresponding side is elongated, so that the compartment plate is raised, thereby adjusting the center of gravity of the goods and keeping the balance of the transfer vehicle. This attitude adjustment function can correct the attitude deviation of the transfer vehicle in time, ensure that the goods are always in a stable state, reduce the risk of goods damage, and also reduce the additional stress on the structure of the transfer vehicle due to unstable attitude, prolonging the service life of the transfer vehicle.

[0019] In summary, the design of the heavy full-remote control electric drive flat transfer vehicle in structure, operation and attitude adjustment has many significant beneficial effects in heavy goods transfer. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical scheme and advantages of the present application clearer and more understandable, the present application will be further described in detail below in combination with embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not to limit the present application.

[0022] Embodiment one To solve the technical problems in the background art, the following heavy full-remote control electric drive flat transfer trolley is given: In combination Figures 1-8 As shown in the figure, a heavy full-remote control electric drive flat transfer trolley comprises a wheel set 4 and a transmission mechanism 2 supported by an H-shaped main frame 1, a panel 5 is supported on the main frame 1, and a tuning assembly 3 is arranged below the main frame 1 for posture adjustment of the transfer trolley. The main frame 1 comprises symmetrical longitudinal beams 11 and crossbars 12 arranged therebetween, a transmission frame 21 is arranged on the crossbars 12, and the wheel set 4 is coupled and connected to the main frame 1 at both ends of the transmission frame 21. The tuning assembly 3 comprises a second tuning mechanism 32, which comprises transverse oil cylinders 322 and longitudinal oil cylinders 321 arranged on both sides of the main frame 1. The transverse oil cylinders 322 and the longitudinal oil cylinders 321 are connected to the panel 5 for lifting adjustment of the panel 5.

[0023] Please refer to the attached drawingsFigures 1-8 The present application provides a first embodiment of a heavy-duty full-remote-control electrically-driven flat transfer vehicle. The heavy-duty full-remote-control electrically-driven flat transfer vehicle mainly consists of an H-shaped main frame 1 as the core support structure. The H-shaped main frame 1 supports the wheel set 4 and the transmission mechanism 2, providing a solid foundation for the normal operation of the transfer vehicle. The main frame 1 is provided with a compartment plate 5 for loading goods, and a tuning assembly 3 is arranged below the compartment plate 5. The core function of the tuning assembly 3 is to accurately adjust the posture of the transfer vehicle.

[0024] Specifically, the main frame 1 is composed of symmetrical longitudinal beams 11 and cross bars 12 connecting the longitudinal beams 11. The battery pack 13 is arranged in the longitudinal beam 11 to provide power. The symmetrical design of the longitudinal beams 11 makes the main frame 1 more stable and balanced in structure, and the cross bars 12 further enhance the overall rigidity and stability of the main frame 1. The transmission frame 21 is arranged on the cross bar 12, and the wheel set 4 arranged at both ends of the transmission frame 21 is connected with the main frame 1 through a specific coupling mode. This connection mode ensures that the wheel set 4 and the main frame 1 can effectively transmit power and torque. The transmission mechanism 2 drives the wheel set 4 to rotate, thereby providing the transfer vehicle with the power to move flexibly.

[0025] Further, the second tuning mechanism 32 in the tuning assembly 3 is the key part to realize the posture adjustment. It contains the horizontal oil cylinder 322 and the vertical oil cylinder 321 arranged on both sides of the main frame 1, which are connected with the compartment plate 5. The extension and retraction of the horizontal oil cylinder 322 and the vertical oil cylinder 321 can adjust the lifting of the compartment plate 5. When it is necessary to change the height or inclination angle of the compartment plate 5, the control system will issue instructions to the corresponding oil cylinder according to the actual situation. The oil cylinder accurately adjusts the position and posture of the compartment plate 5 through the extension and retraction of the piston rod, so as to adapt to different transportation needs and road conditions.

[0026] In addition, the transmission frame 21 is also provided with a pressure sensor for real-time monitoring of the stress between the wheel set 4 and the main frame 1. The pressure sensor feeds back data to the control system, which can adjust the transmission mechanism 2 and the oil cylinder according to the stress condition, to ensure the stability and safety of the transfer vehicle during operation. Through the cooperation of multiple sensors and the accurate control system, the heavy-duty full-remote-control electrically-driven flat transfer vehicle can accurately adjust the posture of the compartment plate 5 under different working conditions, ensuring the stability and safety of the goods transportation.

[0027] Embodiment Two As shown in the above embodiment, the present embodiment further gives the following contents: Figures 6-8 In this embodiment, the second tuning mechanism 32 is provided with a supporting oil cylinder 323, which is arranged on the transmission frame 21 in an interleaved manner and is in contact with the center top of the compartment plate 5, for balancing adjustment of the compartment plate 5.

[0028] ​The transverse oil cylinder 322 and the longitudinal oil cylinder 321 are arranged in a transverse and longitudinal staggered manner and are respectively connected with the edges of the compartment plate 5, and the compartment plate 5 is translated up and down by traction of the oil cylinders.

[0029] Please refer to the drawings in the description Figures 6-8 The second embodiment of the second synchronization mechanism 32 in the synchronization assembly 3 of the heavy-duty full-remote electric drive flat transfer vehicle is provided. In this embodiment, the second synchronization mechanism 32 is mainly used for adjusting the attitude and balance of the compartment plate 5 of the heavy-duty full-remote electric drive flat transfer vehicle, which is composed of a supporting oil cylinder 323, a transverse oil cylinder 322 and a longitudinal oil cylinder 321.

[0030] The supporting oil cylinder 323 is a key component for adjusting the balance of the compartment plate 5. It is arranged in a staggered manner on the transmission frame 21 and is in contact with the center top of the compartment plate 5. During the driving process of the transfer vehicle, due to factors such as uneven transfer road surface and uneven distribution of goods, the compartment plate 5 may be unbalanced. At this time, the supporting oil cylinder 323 will respond according to the signal from the attitude sensor. The attitude sensor monitors the inclination angle and balance state of the compartment plate 5 in real time, and once the unbalance of the compartment plate 5 is detected, the control system will immediately control the supporting oil cylinder 323 to extend and retract. For example, when one side of the compartment plate 5 is higher, the supporting oil cylinder 323 in the corresponding direction will extend to exert an upward force on the center of the compartment plate 5, and through the coordinated action with other oil cylinders, the compartment plate 5 will restore balance.

[0031] The transverse oil cylinder 322 and the longitudinal oil cylinder 321 are arranged in a transverse and longitudinal staggered manner and are respectively connected with the edges of the compartment plate 5, and the compartment plate 5 is translated up and down by traction of the oil cylinders.

[0032] In the specific working process, the control system will comprehensively consider the driving state of the transfer vehicle, the weight distribution of the goods and the road surface conditions and other factors to cooperatively control the supporting oil cylinder 323, the transverse oil cylinder 322 and the longitudinal oil cylinder 321. For example, when turning, in order to prevent the goods from shifting due to centrifugal force, the control system will adjust the state of the oil cylinder in advance to keep the compartment plate 5 balanced and stable. Through the close cooperation and accurate control of the oil cylinders in the second synchronization mechanism 32, the heavy-duty full-remote electric drive flat transfer vehicle can effectively adjust the attitude and balance of the compartment plate 5 under various complex working conditions, ensuring the safety and stability of goods transportation.

[0033] Embodiment three As Figures 1-10As shown, on the basis of the above embodiment, the embodiment further gives the following content: In the embodiment, the transmission mechanism 2 comprises a motor 22 and a speed reducer 23 respectively attached to both ends of the transmission frame 21, the top of the motor 22 is provided with a buffer layer for shock absorption, the speed reducer 23 is connected with the wheel set 4 in a sleeve manner, and the motor 22 and the speed reducer 23 can move up and down along the transmission frame 21; the wheel set 4 comprises a roller shaft 41 inserted into the speed reducer 23, and hollow wheels 42 are respectively sleeved on both ends of the roller shaft 41.

[0034] The synchronous assembly 3 comprises a first synchronous mechanism 31, which comprises a swing spoon 311 sleeved on both ends of the roller shaft 41, the rear end of the swing spoon 311 is connected with the front part of the main frame 1 and swings up and down with the roller shaft 41, and a hinge seat 313 is arranged above the swing spoon 311 at the end of the longitudinal beam 11, and an extension sleeve 312 is connected therebetween, so as to swing and pull the main frame 1 with the wheel set 4.

[0035] The top of the swing spoon 311 is inserted with a butt spring 3111 and a longitudinal beam 11, and a damping spring 3112 is sleeved on the outer periphery of the swing spoon 311 to limit the displacement of the swing spoon 311.

[0036] Please refer to the drawings in the description Figures 1-10 The third embodiment of the heavy full-remote control electric drive flat transfer vehicle is provided.

[0037] The transmission mechanism 2 comprises a motor 22 and a speed reducer 23 respectively attached to both ends of the transmission frame 21, the top of the motor 22 is provided with a buffer layer for shock absorption, the speed reducer 23 is connected with the wheel set 4 in a sleeve manner, and the motor 22 and the speed reducer 23 can move up and down along the transmission frame 21; the wheel set 4 comprises a roller shaft 41 inserted into the speed reducer 23, and hollow wheels 42 are respectively sleeved on both ends of the roller shaft 41.

[0038] The first tuning mechanism 31 is arranged on the tuning assembly 3, and the core is a double-sided swing spoon 311 device sleeved on the roller 41. The rear end of the swing spoon 311 is hinged with the equipment main frame 1, so that the swing spoon 311 can produce spatial displacement with the roller 41. More importantly, the swing spoon 311 is dynamically connected with the end of the longitudinal beam 11 through a hinged seat 313, and a telescopic sleeve 312 mechanism is arranged therebetween. The telescopic sleeve 312 produces telescopic movement when the wheel set 4 rises and falls, thereby dragging the main frame 1 to produce cooperative displacement. The top end of the swing spoon 311 is designed as an interfacial spring 3111 penetrating the longitudinal beam 11 in the axial direction, so that the longitudinal beam 11 and the swing spoon 311 form an elastic connection, and a damping spring 3112 annular structure is additionally arranged on the outer periphery of the swing spoon 311, which limits the abnormal displacement amplitude of the swing spoon 311 through pre-tightening force.

[0039] The operation mechanism mainly embodies two dimensions: in the dynamic balance dimension, the telescopic sleeve 312 provides a rigid guide track for the movement of the wheel set 4, and the swing spoon 311 constitutes a double-limiting mechanism through the elastic reset of the interfacial spring 3111 and the damping constraint of the damping spring 3112. When the equipment passes through the undulating road surface, the displacement of the wheel set 4 drives the swing spoon 311 to deflect through the roller 41, and at this time the rigid guide of the telescopic sleeve 312 and the cooperative action of the elastic element significantly buffer the impact load received by the main frame 1. In the passability dimension, when it is necessary to pass through complex terrain, the oil cylinder drives the compartment plate 5 to press down, drives the motor 22 to drag the reducer 23 unit to sink as a whole, so that the height of the wheel set 4 is lowered. At this time, the swing spoon 311 is angularly deflected with the downward movement of the roller 41, the telescopic sleeve 312 is contracted and drags the main frame 1 to increase the elevation angle, so as to realize the lifting of the ground clearance of the main frame 1. In the full-load working condition, the cooperative movement can make the equipment efficiently avoid the roadblock and avoid the scraping collision of the main frame 1 chassis.

[0040] Further explanation of the working logic of the elastic limiting system: the swing spoon 311 forms an elastic connection with the longitudinal beam 11 through the interfacial spring 3111, which allows it to deflect within the designed range; at the same time, the damping spring 3112 restricts the lateral displacement of the swing spoon 311 in the form of ring wrapping. When the wheel set 4 encounters a road surface protrusion, the roller 41 lifts to push the rear end of the swing spoon 311 to swing upward, at this time the interfacial spring 3111 produces tensile deformation to absorb kinetic energy, and the damping spring 3112 is compressed to suppress lateral shaking. When the wheel set 4 encounters a pit, the roller 41 falls to drive the swing spoon 311 to lean forward, the interfacial spring 3111 is compressed to store potential energy, and the damping spring 3112 is stretched to prevent the main frame 1 from deviating. This three-dimensional elastic limiting mechanism ensures that the movement track of the main frame 1 is always within a controllable range.

[0041] In the preferred embodiment, the connection between the main frame 1 and the swing spoon 311 adopts a universal joint structure to ensure freedom in all directions; the reducer 23 and the roller 41 are connected by a spline to ensure efficient transmission; the buffer layer is made of high-damping composite material; and the telescopic sleeve 312 is designed as an inner and outer tube stacked structure. When the equipment enters special terrain, the hydraulic cylinder actuator system is activated first, driving the motor 22 and wheel assembly 4 modules to descend as a whole; at this time, the descent of the wheel assembly 4 causes the swing spoon 311 to increase its tilt angle, while the telescopic sleeve 312 extends to pull the main frame 1 to rise as a whole, so that the main frame 1 forms a boat-shaped passage posture. Without changing the structural strength of the main frame 1, the passability of the equipment is substantially improved through mechanical coupling.

[0042] In summary, after a complete mechanical cycle: road impact causes the wheel set 4 to shift, driving the roller 41 to rotate, which in turn causes the swing scoop 311 to deflect, thus extending and retracting the telescopic sleeve 312 to buffer the main frame 1, ultimately maintaining the equipment's operational stability under complex working conditions. The essence of this technical solution lies in the coupling design of the liftable transmission platform and the elastic linkage mechanism, achieving the equipment's terrain-adaptive function in a purely mechanical way.

[0043] Example 4 like Figures 3-10 As shown, based on the above embodiments, this embodiment further provides the following: In this embodiment, wheel cavities 211 are symmetrically arranged on both sides of the crossbar 12, which are adapted to the outer periphery of the hollow wheel 42 and are used for anti-deviation positioning of the wheel set 4.

[0044] Rubber pads 15 are embedded in the middle part of the longitudinal beams 11 and are pressed down on the box panel 5 for elastic transition of the transport vehicle's posture adjustment.

[0045] The outer perimeter of the panel 5 is provided with a barrier 54 to prevent goods from slipping off.

[0046] The bottom wall edge of the panel 5 is symmetrically provided with hinge points 52 and center support points 53, and center support points 53 are provided at the four corners of the center for rapid response of the transfer vehicle's attitude adjustment.

[0047] Please refer to the instruction manual appendix. Figures 3-10 This invention provides a fourth embodiment of a heavy-duty fully remote-controlled electric-driven flatbed transport vehicle. In this embodiment, the transport vehicle achieves functions such as wheel assembly 4 positioning, attitude adjustment, and cargo protection through the coordinated operation of components such as crossbars 12, longitudinal beams 11, and side panels 5.

[0048] The crossbar 12 plays a role of preventing the wheel set 4 from deviating in the transfer trolley. The crossbar 12 is symmetrically provided with wheel cavities 211 on both sides, which are adapted to the outer periphery of the hollow wheel 42. When the wheel set 4 is running, the hollow wheel 42 is located in the wheel cavity 211, which can limit the lateral movement of the hollow wheel 42, ensure the wheel set 4 to run along the predetermined track, prevent the wheel set 4 from deviating, and thus ensure the stability of the vehicle running.

[0049] The longitudinal beam 11 plays an important role in the posture adjustment of the transfer trolley. The middle part of the longitudinal beam 11 is respectively embedded with rubber pads 15, which will be elastically contacted with the chamber plate 5 when the chamber plate 5 is pressed down. During the running of the vehicle, the posture of the vehicle may change due to uneven road surface or uneven distribution of goods. At this time, the chamber plate 5 will generate pressure on the longitudinal beam 11, and the elastic property of the rubber pad 15 enables it to play a role of buffering and transition between the chamber plate 5 and the longitudinal beam 11, realizing the elastic transition of the posture adjustment of the transfer trolley, and avoiding the occurrence of violent vibration and impact during the posture adjustment process.

[0050] The chamber plate 5 not only serves as a component for carrying goods, but also has the functions of protection and posture adjustment response. The chamber plate 5 is annularly provided with a fence 54, which can effectively prevent the goods from falling off during transportation, thereby ensuring the safety of goods transportation. The bottom wall edge of the chamber plate 5 is symmetrically provided with hinge support points 52 hinged with the transverse oil cylinder 322 and top support points 51 contacted with the longitudinal oil cylinder 321, and the center of the four corners is also provided with middle support points 53 connected with the supporting oil cylinder 323. When the transfer trolley needs to be adjusted in posture, these support points can quickly respond in cooperation with the second harmonic mechanism 32. For example, when the vehicle encounters uneven road surface or performs height-limited space operation, etc., the adjusting device such as the oil cylinder can exert force on the chamber plate 5 through these support points, so that the chamber plate 5 can quickly make corresponding posture adjustment, thereby driving the whole transfer trolley to change the posture.

[0051] During the actual running of the vehicle, the components cooperate with each other. When the posture of the vehicle needs to be adjusted, the chamber plate 5 is pressed down, the rubber pad 15 on the longitudinal beam 11 plays an elastic transition role, and the support points on the chamber plate 5 can quickly respond to the adjustment instruction. The wheel set 4 stably runs under the limitation of the wheel cavity 211 of the crossbar 12, ensuring the straightness of the vehicle running. The fence 54 of the chamber plate 5 always guards the safety of the goods, ensuring that the goods will not fall off during transportation. Through the cooperative work of these components, the heavy-duty full-remote electric drive flat transfer trolley can stably and safely transport goods under complex working conditions.

[0052] The working principle and use process of the present application are as follows: The use flow starts from pre-operation inspection, ensuring that the main frame 1, the wheel set 4 and the transmission mechanism 2 are normally assembled, the longitudinal beams 11 and the cross bars 12 on the main frame 1 are coupled well, the motors 22 and the speed reducers 23 at the two ends of the transmission frame 21 are normally installed, the buffer layer on the top of the motor 22 is intact, the motor 22, the speed reducer 23 and the wheel set 4 are connected in sequence, the oil cylinders of the same tuning assembly 3 (including the first and second same tuning mechanisms 32) are correctly connected, the rubber pads 15 in the middle of the longitudinal beams 11 are normally embedded, and the surrounding barriers 54 are arranged on the outer periphery of the compartment plate 5.

[0053] After starting the transfer vehicle, the transmission mechanism 2 starts to work: the motor 22 drives the speed reducer 23, which drives the rolling shaft 41 of the wheel set 4 to rotate, so that the hollow wheel 42 rolls to push the vehicle to move. During the movement, the motor 22 and the speed reducer 23 can move up and down along the transmission frame 21 to adapt to different road conditions. When passing through uneven roads and limited height spaces, the second same tuning mechanism 32 is started by remote control, the horizontal oil cylinder 322 and the vertical oil cylinder 321 arranged in a horizontal and vertical staggered manner on the two sides of the main frame 1 pull the edges of the compartment plate 5, so as to realize the lifting adjustment of the compartment plate 5; at the same time, the supporting oil cylinder 323 is arranged on the transmission frame 21 in a staggered manner and is in contact with the center top of the compartment plate 5 to perform the balance adjustment of the compartment plate 5. In addition, the first same tuning mechanism 31 operates, the rolling shaft 41 swings up and down to drive the swing spoon 311 sleeved on both ends of the rolling shaft 41 to swing, the rear end of the swing spoon 311 is connected with the front part of the main frame 1, and the upper telescopic sleeve 312 pulls the main frame 1 by swinging with the wheel set 4; the butt spring 3111 on the top of the swing spoon 311 is connected with the longitudinal beam 11 in a penetrating manner, and the shock absorbing spring 3112 on the outer periphery limits the displacement thereof. When the compartment plate 5 is pressed down, the rubber pad 15 in the middle of the longitudinal beam 11 elastically contacts the compartment plate 5, so as to provide an elastic transition for the attitude adjustment, and the hinge support point 52, the middle support point 53 on the bottom wall of the compartment plate 5 and the middle support points 53 on the four corners of the center quickly respond to the adjustment instruction, so as to realize the attitude adjustment. When transporting goods, the surrounding barriers 54 on the outer periphery of the compartment plate 5 effectively prevent the goods from falling off. If it is necessary to reduce the height of the whole vehicle, the oil cylinder pulls the compartment plate 5 to fall to reduce the wheel set 4, and cooperates with the swing spoon 311 and the telescopic sleeve 312 to realize the height reduction of the whole vehicle. The whole process can realize the cooperative work of the components through remote control, so as to ensure stable transportation.
