Description

Technical Field

[0001] This application relates to the field of flipping machine technology, and more specifically, to a hydraulic flipping machine that can move laterally. Background Technology

[0002] Hydraulic tipping machines are modern loading and unloading equipment widely used in logistics, grain, and chemical industries. Their core function is to use a hydraulic system to drive a large tipping plate, adjusting its tilt angle to dock with the truck bed, enabling rapid and efficient unloading of bulk materials or standardized pallets. This type of equipment significantly improves the mechanization level and efficiency of loading and unloading operations.

[0003] However, most mainstream hydraulic tippers on the market currently employ a traditional "two-drive, two-driven" mechanism, meaning they are equipped with two drive wheels and two driven wheels. In practical applications, especially in confined warehouses or areas requiring precise alignment, this reveals significant limitations. When the equipment needs to be moved slightly, shifted laterally, or adjusted to a specific angle, operators must perform a series of tedious and non-intuitive complex operations involving "forward-turning-backward-turning." This "zigzag" movement method is not only cumbersome and time-consuming, but also increases the safety risk of collisions with surrounding equipment or buildings due to the unpredictable movement trajectory, severely restricting operational efficiency and site adaptability.

At this time, it is in a moving state. In the second state, the telescopic component retracts, causing the wheel body to rise and the wheel frame to descend to contact the ground, so that the wheel frame bears the overall weight of the hydraulic tipper, at which point it is in a parked state.

Detailed Implementation

[0017] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0018] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movement of the components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0019] Please refer to Figure 1 and Figure 3 This application provides a laterally movable hydraulic tipper, including a tipping mechanism 100 and a moving mechanism 200. The tipping mechanism 100 includes a loading platform for carrying a truck; the moving mechanism 200 includes at least three units, fixedly connected to the bottom of the tipping mechanism 100. Specifically, there can be four units, symmetrically installed in pairs on both sides of the tipping mechanism 100. Figure 2 , Figure 4 and Figure 5 Each moving mechanism 200 includes: a wheel frame 210, a wheel body 220, a drive assembly 230, and a steering assembly 240; the wheel frame 210 is fixedly connected to the flipping mechanism 100, the wheel body 220 is rotatably mounted on the wheel frame 210 via its axle 221, the drive assembly 230 is drivenly connected to the wheel body 220 for driving the wheel body 220 to rotate, and the steering assembly 240 is drivenly connected to the axle 221 for driving the wheel body 220 to rotate around an axis perpendicular to the ground; the drive assembly 230 and the steering assembly 240 of each moving mechanism 200 are configured to be independently controllable, driving the wheel body 220 to rotate or turn, causing the flipping mechanism 100 to move laterally, and in addition, it can also produce omnidirectional movement including forward, backward, and rotation in place.

[0020] Each moving mechanism 200 is an independent motion unit, with its steering angle controlled by the steering component 240 and its rotation speed controlled by the drive component 230. Each moving mechanism 200 can be precisely and independently coordinated and controlled by the control system. By assigning different motion vectors to each wheel, different movement modes of the entire device can be synthesized. The steering angles of all four wheels are kept consistent, parallel to the main axis of the device. Subsequently, all wheels 220 are synchronously driven to rotate in the same direction. When all wheels 220 rotate forward, the entire device moves forward; when all wheels 220 rotate backward, the entire device moves backward. The steering component 240 controls the steering angle of all four wheels to rotate 90°, making them perpendicular to the main axis of the device. Subsequently, the drive component 230 synchronously drives all wheels 220 to rotate in the same direction. At this time, the direction of the wheel 220's rolling is the lateral movement direction of the device. This lateral movement solves the core pain point of lateral displacement in narrow spaces. The device does not need repeated forward and backward adjustments and can directly move to the target position, greatly improving work efficiency and positioning accuracy.

[0021] The two front wheels 220 and the two rear wheels 220 are controlled to turn at +90° and -90° angles respectively, and then the drive assembly 230 causes the wheels 220 to rotate. This allows the equipment to make a 360° turn around its own center. This is crucial when changing direction at the end of a passage or in extremely limited space, reducing the space required for turning. Therefore, this application can realize the omnidirectional rotation of the hydraulic tipper.

[0022] refer to Figure 5 and Figure 6In one embodiment, the wheel 220 is connected to the wheel frame 210 via a telescopic assembly 300. The telescopic assembly 300 includes a first state and a second state. In the first state, the telescopic assembly 300 extends, driving the wheel 220 down to contact the ground and raising the wheel frame 210, allowing the wheel 220 to bear the overall weight of the hydraulic tipper; in this state, it is in motion. In the second state, the telescopic assembly 300 retracts, driving the wheel 220 up and lowering the wheel frame 210 down to contact the ground, allowing the wheel frame 210 to bear the overall weight of the hydraulic tipper; in this state, it is in a stationary state. The wheel 220 is connected to the wheel frame 210 via the telescopic assembly 300. In the first state, the telescopic assembly 300 extends, pressing the wheel 220 down to contact the ground while raising the wheel frame 210, allowing the entire equipment to be carried by the wheel 220, thus achieving the motion function. In the second state, the retraction drives the wheel 220 up, causing the wheel frame 210 to fall back to the ground to bear the weight of the equipment, thus achieving stable parking. The telescopic assembly 300 can reliably switch the equipment between moving and stationary states, ensuring both flexibility during movement and stability during stationary operation. The telescopic assembly 300 can be implemented using linear drive components such as hydraulic cylinders or pneumatic cylinders, which provide sufficient thrust and holding force to meet the operating requirements of heavy equipment.

[0023] In one embodiment, the wheel frame 210 includes two parallel vertical support beams 211, a top connecting beam 212 fixedly connected to the top ends of the two vertical support beams 211, and a middle connecting beam 213 located in the middle. The upper end of the telescopic assembly 300 is mounted on the top connecting beam 212, and its main body passes downward through the middle connecting beam 213 and is connected to the wheel body 220. The wheel frame 210 adopts a frame structure of two vertical support beams 211 in conjunction with the top connecting beam 212 and the middle connecting beam 213. This structure has sufficient strength and rigidity to support the weight of the hydraulic tipper and transfer it to the foundation. To further enhance stability and load-bearing capacity, triangular connecting blocks can be set at the connection between the crossbeams and vertical beams to distribute stress, and triangular support feet with a larger contact area can be installed at the bottom of the vertical beams. These measures enable the equipment to be placed more stably on the ground when parked, resisting the risk of overturning due to uneven load or slight uneven ground.

[0024] refer to Figure 6 and Figure 7In one embodiment, the intermediate connecting beam 213 has a first guide hole 214, and the side wall of the first guide hole 214 has at least two opposing mounting grooves 215. Each mounting groove 215 contains a plurality of rollers 216 that can rotate around their own axis. The axes of the plurality of rollers 216 are collinear, and their wheel surfaces are used to abut against the surface of the telescopic component 300 passing through the first guide hole 214. The side wall of the first guide hole 214 of the intermediate connecting beam 213 has mounting grooves 215, in which a plurality of collinear rollers 216 are installed. The wheel surfaces of these rollers 216 contact the surface of the telescopic component 300 passing through, transforming traditional sliding friction into rolling friction. When the telescopic component 300 performs a lifting action, the relative movement between it and the intermediate connecting beam 213 is therefore smoother, requiring less driving force, which helps to reduce component wear and energy loss, and extend service life.

[0025] In one embodiment, multiple rollers 216 are connected in series via a first rotating shaft 217. A compression spring 218 is disposed between the first rotating shaft 217 and the inner wall opposite the opening of the mounting groove 215. When the telescopic assembly 300 passes vertically through the first guide hole 214, the compression spring 218 is in a pre-compressed state with a remaining compression margin, allowing the compression spring 218 to be squeezed when the telescopic assembly 300 tilts, thus achieving self-adaptation. The multiple rollers 216 connected in series via the first rotating shaft 217 have a pre-compressed spring with a remaining margin between their rotating shaft and the inner wall of the mounting groove 215. In cases of large equipment size and long leg spacing, the multiple telescopic assemblies 300 may inevitably exhibit asynchronous telescopic movement, causing the intermediate connecting beam 213 to be subjected to lateral compressive force from the tilted telescopic assembly 300. At this point, the spring can be further compressed, allowing the roller 216 assembly to absorb and disperse this lateral energy by allowing slight yielding, effectively reducing the potential damage to the intermediate connecting beam 213 caused by stress concentration, such as cracking, and improving the structural reliability and durability of the wheel frame 210.

[0026] In one embodiment, four rollers 216 are mounted side-by-side on a first rotating shaft 217. The two ends of the first rotating shaft 217 are fixedly connected by a U-shaped connecting frame 219, and a compression spring 218 is disposed between the U-shaped connecting frame 219 and the inner wall of the mounting groove 215. This specific configuration ensures that the four rollers 216 can evenly distribute the load and maintain stable contact with the surface of the telescopic assembly 300. The U-shaped connecting frame 219 evenly distributes the spring force to both ends of the rotating shaft, thereby enabling the entire roller group 216 to respond smoothly and consistently to the tilting of the telescopic assembly 300, enhancing the coordination and effectiveness of the adaptive mechanism.

[0027] refer to Figure 5 and Figure 6In one embodiment, the telescopic assembly 300 includes a leg cylinder 310 and a guide rod 320. The leg cylinder 310 includes a cylinder barrel 311 and a piston rod 312. The cylinder barrel 311 is fixedly installed on the top connecting beam 212, and the end of the piston rod 312 is fixedly connected to the guide rod 320. The guide rod 320 is vertically penetrating and slidably installed in the first guide hole 214 of the intermediate connecting beam 213. The cylinder barrel 311, fixed to the top connecting beam 212, provides thrust, and the piston rod 312 drives the guide rod 320, which slides in the guide hole of the intermediate connecting beam 213. This structure accurately converts the telescopic movement of the cylinder into the lifting and lowering of the wheel 220. The guide rod 320 ensures the straightness of the movement trajectory and prevents uneven loading. When the guide rod 320 has a hexagonal cross-section, and the first guide hole 214 can be provided with mounting grooves 215 with rollers 216 on multiple side walls, this design can adapt to tilting trends from different directions. When the telescopic assembly 300 may tilt in either direction due to asynchrony, the spring assembly of the rollers 216 on the corresponding side can provide effective cushioning, significantly improving the system's fault tolerance to complex working conditions.

[0028] In one embodiment, the wheel 220 is mounted on the bridge support 250 via its axle 221, and a steering sprocket 241 is fixedly mounted on the bottom end of the guide rod 320. The bridge support 250 and the steering sprocket 241 are fixedly connected, so that the steering sprocket 241 can controllably drive the bridge support 250 and the wheel 220 to rotate synchronously. The steering assembly 240 includes a servo motor 242 and a reducer 243 connected to the output end of the servo motor 242. The output shaft of the reducer 243 is connected to the steering sprocket 241. When the servo motor 242 drives the steering sprocket 241 via the reducer 243, the bridge support 250 and the entire wheel 220 can be precisely controlled to rotate around the vertical axis. This layout integrates the steering structure and the telescopic assembly 300 into one compact structure. The servo motor 242, in conjunction with the reducer 243, provides sufficient steering torque and precise angle control, which is the basis for realizing the complex maneuvering actions such as lateral movement, diagonal movement, and stationary rotation of the equipment.

[0029] In one embodiment, the drive assembly 230 is a hydraulic motor, the output end of which is connected to the axle 221 of the wheel 220 to drive the wheel 220 to rotate. The hydraulic motor provides low-speed, high-torque output characteristics, making it ideal for the driving needs of heavy-duty equipment like hydraulic tippers. Its robust structure and strong overload resistance allow it to operate reliably under harsh conditions, ensuring power supply for the equipment in various movement modes.

The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
