Description

Technical Field

[0001] This utility model belongs to the technical field of cargo loading and unloading equipment, and more specifically, relates to a multi-directional, multi-functional ramp-type platform slab. Background Technology

[0002] In the field of modern logistics warehousing and freight transportation, efficient and safe loading and unloading operations are crucial for ensuring the smooth operation of the supply chain. One common challenge is the height difference between the platform and the truck's cargo compartment floor during the transfer of goods between warehouse platforms and transport vehicles (such as trucks). To overcome this obstacle, various height-adjustable platforms or ramps have emerged and are widely used in loading and unloading areas of logistics centers, distribution stations, and manufacturing enterprises. Platform ramps, as a fixed yet adjustable auxiliary tool for balancing the height difference between trucks and platforms, are an important component in this field. Their design aims to pre-define installation dimensions and install the ramp entirely within a pre-reserved recess, using an external control switch to raise or lower the platform to meet the access needs of forklifts and other loading and unloading equipment.

[0003] Currently, existing technologies for addressing the height difference between trucks and platforms primarily focus on the design and application of transom platforms at warehouses. In practice, during the warehouse construction phase, the installation dimensions for the transom platform are pre-planned based on factors such as the expected types of trucks and forklift specifications. Custom-made transom platforms are then installed in the corresponding slots. When trucks stop at the platform for loading and unloading operations, workers can activate the transom platform's lifting system via an external control switch. Typically, this lifting system utilizes hydraulic or electric drives to achieve smooth lifting of the transom platform, thus bridging the height difference between the truck bed and the platform. This allows forklifts to safely and conveniently transport goods between the two, improving loading and unloading efficiency to a certain extent and reducing the workload and potential risks of manual handling.

[0004] However, limited by the fixed height of physical platforms, currently used platform ramps can only be adjusted in one direction. Furthermore, existing products are designed solely around this single adjustment direction, neglecting the flexibility and variability of market demands. For example, in actual logistics scenarios, the height of different types of trucks varies significantly. Besides standard-height trucks, there are modified or special-purpose trucks whose cargo box heights may be higher or lower than the standard range. For these non-standard-height trucks, existing single-direction adjustable ramps often fail to meet the requirements, unable to accurately adapt to the height difference, leading to obstruction of forklift loading and unloading operations, and potentially causing safety accidents such as goods falling or equipment damage. In addition, with the rapid development of the logistics industry, the functions and layouts of warehouses are constantly changing, requiring the connection of various types of transport vehicles in different areas and at different times. Existing ramps, lacking multi-directional adjustment capabilities and flexibility, may not be able to quickly adapt to these dynamic changes, severely restricting the overall efficiency and adaptability of logistics operations and failing to meet the ever-growing demands for efficient and diversified logistics. Utility Model Content

[0005] To address the aforementioned deficiencies or improvement needs of existing technologies, this utility model provides a multi-directional, multi-functional ramp-type platform. Through the coordinated design of a split platform structure and multiple independently driven hydraulic systems, each sub-platform can not only be raised and lowered as a whole to achieve traditional height adjustment, but also perform differentiated raising and lowering operations according to actual working conditions. This effectively adapts to the height differences of cargo box floors of different vehicle models and uneven parking conditions, solving the drawbacks of a single adjustment direction. At the same time, the split structure, combined with a multi-point supported hydraulic drive system, significantly enhances the overall load-bearing capacity and structural stability of the platform, avoiding deformation or fatigue damage caused by concentrated stress in traditional single-unit platforms.

[0006] To achieve the above objectives, this utility model provides a multi-directional, multi-functional ramp-type platform, comprising: a platform, a support assembly located at the bottom of the platform, and a controller located on the working ground and adjacent to the platform; wherein: The ferrule platform includes at least: a first sub-platform, a second sub-platform, and a third sub-platform; the two ends of the second sub-platform are respectively hinged to one end of the first sub-platform and one end of the third sub-platform.

Multiple first electro-hydraulic rods are arranged in a row along the length of the first sub-platform. The movable end of the second electro-hydraulic rod is hinged to the middle of the bottom end of the second sub-platform, and the fixed end is detachably connected to the bottom surface of the mounting hole adapted to the working ground. Multiple second electro-hydraulic rods are arranged in a row along the length of the second sub-platform. The movable end of the third electro-hydraulic rod is hinged to the middle of the bottom end of the third sub-platform, and the fixed end is detachably connected to the bottom surface of the mounting hole adapted to the working ground. Multiple third electro-hydraulic rods are arranged in a row along the length of the third sub-platform. The controller is electrically connected to multiple first electro-hydraulic rods, multiple second electro-hydraulic rods, and multiple third electro-hydraulic rods, and is used to control the synchronous extension and retraction of multiple hydraulic rods in the same row.

[0007] Furthermore, the support component also includes multiple bases, which are evenly distributed at the bottom of the first sub-platform, the second sub-platform, and the third sub-platform.

[0008] Furthermore, the base includes at least two sections along its length. The first section is detachably connected to the bottom surface of the mounting hole on the working ground, and the upper end of the second section is hinged to the bottom end of each sub-platform. The first section and the second section are slidably connected by a dovetail groove guide structure.

[0009] Furthermore, the support assembly also includes a buffer spring, one end of which is fixedly connected to the bottom end of the second segment, and the other end is fixedly connected to the bottom surface of the mounting hole where the first segment is located.

[0010] Furthermore, each of the first sub-platform, the second sub-platform, and the third sub-platform has at least one longitudinally extending positioning stripe on its left and right sides, and the positioning stripes on the same side of adjacent sub-platforms are longitudinally collinear.

[0011] Furthermore, the first sub-platform, the second sub-platform, and the third sub-platform are all made of stainless steel.

[0012] Furthermore, the upper surfaces of the first sub-platform, the second sub-platform, and the third sub-platform are all provided with anti-slip patterns.

[0013] Furthermore, the ramp-type platform slab also includes an overlapping component, which is composed of multiple square plates of the same width that are hinged together in sequence. One end of the overlapping component is detachably fixed to the upper end of the platform, and the other end is detachably fixed to the upper end of the first sub-platform.

[0014] Furthermore, the ramp-type platform slab also includes a lip plate, one end of which is hinged to one end of the third sub-platform, and its length is the same as that of the third sub-platform and its width is 20cm to 50cm.

[0015] In summary, compared with the prior art, the above-described technical solution conceived by this utility model can achieve the following beneficial effects: 1. The platform transition plate of this utility model connects the first, second, and third sub-platforms sequentially via hinges to form a transition plate platform, creating a flexible, multi-segment transition structure.

Furthermore, the coordinated design of the split platform structure and multiple independently driven hydraulic systems enables the sub-platforms to not only lift and lower as a whole to achieve traditional height adjustment, but also to perform differentiated lifting operations based on actual working conditions. This effectively adapts to the height differences of cargo box floors in different vehicle models and uneven parking conditions, overcoming the drawbacks of a single adjustment direction.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model. Furthermore, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0022] Please refer to Figures 1 to 4 One embodiment of this utility model provides a multi-directional, multi-functional ramp-type platform, comprising: a ramp platform 3, a support assembly 4 disposed at the bottom end of the ramp platform, and a controller 5 disposed on the working ground 1 and adjacent to the ramp platform 3; wherein: The ferrule platform 3 includes at least: a first sub-platform 31, a second sub-platform 32, and a third sub-platform 33; the two ends of the second sub-platform 32 are respectively hinged to one end of the first sub-platform 31 and one end of the third sub-platform 33; The support assembly 4 includes at least: a plurality of first electro-hydraulic rods 41, a plurality of second electro-hydraulic rods 42 and a plurality of third electro-hydraulic rods 43; The movable end of the first electro-hydraulic rod 41 is hinged to the middle of the bottom end of the first sub-platform 31 and the fixed end is fixedly disposed on the working ground 1. Multiple first electro-hydraulic rods 41 are arranged in a row along the length of the first sub-platform 31. The movable end of the second electric hydraulic rod 42 is hinged to the middle of the bottom end of the second sub-platform 32, and the fixed end is detachably connected to the bottom surface of the mounting hole that is adapted to the working ground 1. Multiple second electric hydraulic rods 42 are arranged in a row along the length of the second sub-platform 32. The movable end of the third electric hydraulic rod 43 is hinged to the middle of the bottom end of the third sub-platform 33 and the fixed end is detachably connected to the bottom surface of the mounting hole adapted to the working ground 1. Multiple third electric hydraulic rods 43 are arranged in a row along the length direction of the third sub-platform 32. The controller 5 is electrically connected to a plurality of first electro-hydraulic rods 41, a plurality of second electro-hydraulic rods 42 and a plurality of third electro-hydraulic rods 43, and is used to control the synchronous extension and retraction of a plurality of hydraulic rods in the same column.

[0023] During use, the first sub-platform 31, the second sub-platform 32, and the third sub-platform 33 are connected sequentially via hinges to form the transition platform 3, creating a flexible, multi-segment transition structure. This is combined with multiple sets of electro-hydraulic rods located at the bottom of each sub-platform. The movable ends of each set of hydraulic rods are hinged to the center of the corresponding sub-platform's bottom, while the fixed ends are securely installed in pre-set mounting holes on the working surface 1, arranged in a row along the length of each sub-platform. This allows for convenient and precise independent height control of each sub-platform via the controller 5. It is understood that the coordinated design of the split platform structure and multiple independently driven hydraulic systems enables the sub-platforms to not only lift and lower as a whole to achieve traditional height adjustment, but also to perform differentiated lifting operations based on actual working conditions. This effectively adapts to the height differences of cargo box floors in different vehicle models and uneven parking conditions, overcoming the drawbacks of a single adjustment direction. Simultaneously, the split structure, combined with a multi-point supported hydraulic drive system, significantly enhances the overall load-bearing capacity and structural stability of the platform, avoiding deformation or fatigue damage caused by concentrated stress in traditional single-unit platforms.

[0024] Please refer to Figures 1 to 4 The support component 4 also includes multiple bases 44, which are evenly distributed at the bottom of the first sub-platform 31, the second sub-platform 32 and the third sub-platform 33. These bases provide additional support strength and structural stability when the transfer platform 3 is under heavy load, effectively disperse concentrated loads, reduce the risk of platform deformation, enhance overall rigidity, extend equipment service life, and ensure the safe passage of forklifts and other loading and unloading equipment.

[0025] In an optional embodiment, the base 44 includes at least two sections along its length. The first section 441 is detachably connected to the bottom surface of the mounting hole on the working ground 1, and the upper end of the second section 442 is hinged to the bottom end of each sub-platform. The first section 441 and the second section 442 are slidably connected through a dovetail groove guide structure. This ensures the structural strength of the base 44 while allowing it to achieve stable guidance and slight radial adjustment during lifting, effectively absorbing lateral stress, reducing movement jamming, improving the smoothness and reliability of the operation of the first electro-hydraulic rod 41, the second electro-hydraulic rod 42, and the third electro-hydraulic rod 43, and extending the service life of the support assembly 4.

[0026] In an optional embodiment, the support component 4 further includes a buffer spring 45, one end of which is fixedly connected to the bottom end of the second segment 442, and the other end is fixedly connected to the bottom surface of the mounting hole where the first segment 441 is located. This buffer spring provides elastic cushioning when the platform 3 is subjected to dynamic loads or sudden impacts, effectively absorbs vibration energy, reduces the structural stress of the base 44 and the support component 4, improves the stability and safety of the operation of the first sub-platform 31, the second sub-platform 32 and the third sub-platform 33, and extends the overall service life of the equipment.

[0027] Please refer to Figures 1 to 3 Each of the first sub-platform 31, the second sub-platform 32, and the third sub-platform 33 has at least one longitudinally extending positioning stripe 34 on its left and right sides. The positioning stripes 34 on the same side of adjacent sub-platforms are longitudinally collinear. This allows for visual observation of the alignment of the positioning stripes 34 between each sub-platform, enabling convenient judgment and adjustment of the relative position of each sub-platform. This ensures precise alignment during lifting or tilting, prevents misalignment, improves the intuitiveness and safety of operating the transfer platform 3, and ensures smooth and stable forklift passage.

[0028] It is understood that when the positioning strips 34 are used in conjunction with the electric hydraulic rod to adjust the height of the ferrule platform 3, the height of the first sub-platform 31, the second sub-platform 32 and the third sub-platform 33 in the horizontal state is adapted to the height of the ground of the platform 2, so as to eliminate the height difference between the platform and the ferrule, form a continuous and flat working plane, facilitate the smooth passage of forklifts and personnel between the platform and the ferrule, significantly improve the safety of operation and loading and unloading efficiency, and at the same time avoid impact damage to the equipment caused by the height difference. Furthermore, the angle between the ramp platform 3 and the ground of the platform 2 is within the range of ±10°. This angle range is set with full consideration of the power performance, tire grip, center of gravity distribution, and operating habits of loading and unloading tools such as forklifts. This ensures that forklifts can smoothly and safely ascend and descend the ramp platform 3 during ramp operation, effectively preventing safety hazards such as slippage, rollover, or brake failure caused by excessively steep slopes. At the same time, this angle range not only meets the adjustment needs of the common height difference between the cargo box floor of most trucks and the platform 2, but also avoids the additional load on the forklift transmission system and hydraulic system caused by excessive tilting, thus extending the service life of the equipment.

[0029] In an optional embodiment, the first sub-platform 31, the second sub-platform 32, and the third sub-platform 33 are all made of stainless steel to adapt to harsh working conditions such as humidity and heavy load, and to extend the service life of the equipment.

[0030] In an optional embodiment, the upper surfaces of the first sub-platform 31, the second sub-platform 32, and the third sub-platform 33 are all provided with anti-slip patterns to enhance the friction between the forklift tires and the platform, effectively prevent slippage accidents under wet or oily conditions, ensure the safety of personnel and equipment during loading and unloading operations, and improve the overall reliability and safety of the transfer platform 3.

[0031] In an optional embodiment, the ramp-type platform slab further includes an overlapping member 6, which is composed of multiple square plates of the same width hinged together in sequence. One end of the overlapping member 6 is detachably fixed to the upper end of the platform 2, and the other end is detachably fixed to the upper end of the first sub-platform 31. This allows for adaptive adjustment of the bending angle during the lifting and lowering of the platform 3, effectively filling the gap between the platform 1 and the first sub-platform 31, forming a continuous and flat passage surface, preventing forklift wheels from getting stuck, and improving passage safety and operational efficiency. At the same time, its detachable design also facilitates later maintenance, replacement, and partial repair, significantly improving the flexibility of use and maintenance efficiency of the platform 3.

[0032] In an optional embodiment, the ramp-type platform slab further includes a lip plate 7, one end of which is hinged to one end of the third sub-platform 33. The lip plate 7 has the same length as the third sub-platform 33 and a width of 20cm to 50cm. It is used to flip outward and overlap the truck bed floor or working ground 1 after the third sub-platform 33 is raised and lowered to the target height, forming a stable transition connection, effectively extending the working range, preventing forklifts from overturning, and improving the safety and adaptability of loading and unloading operations.

[0033] In an optional embodiment, the controller 5 includes: a memory processor and a communication module; the memory is used to store a basic program for controlling the extension and retraction of the electro-hydraulic rod; the processor is used to control the extension and retraction of the electro-hydraulic rod based on the basic program; and the communication module is used for data exchange and remote control with other devices.

[0034] It is understood that the memory can be high-speed RAM or non-volatile memory, such as at least one disk storage device; optionally, the memory can also be at least one storage device located remotely from the processor. The processor can be a central processing unit (CPU), or it can be other general-purpose processors, DSPs, ASICs, FPGAs, or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc.; the general-purpose processor can be a microprocessor or any conventional processor. The communication module includes standard wired interfaces and wireless interfaces (such as Wi-Fi interfaces) and can provide network communication functionality.

[0035] The working principle of this utility model is as follows: When the truck stops near platform 2, the operator activates controller 5 to send control signals to multiple first electric hydraulic rods 41, multiple second electric hydraulic rods 42, and multiple third electric hydraulic rods 43 in the same row, adjusting the extension and retraction stroke of each set of hydraulic rods. Since the movable end of the first electric hydraulic rod 41 is hinged to the middle of the bottom end of the first sub-platform 31, and the second electric hydraulic rods 42 and the second sub-platform 32, and the third electric hydraulic rods 43 and the third sub-platform 33 are all connected in the same way, and the fixed ends of each hydraulic rod are firmly installed in the mounting holes of the working ground 1, the extension and retraction movement of the hydraulic rods can drive the corresponding sub-platforms to achieve independent operation. Alternatively, it can be raised and lowered in tandem; by precisely controlling the synchronous movement of each hydraulic rod, one end of the first sub-platform 31 can be raised and lowered to be flush with the cargo box floor, ensuring smooth passage of the forklift; at the same time, during the raising and lowering process, the dovetail groove guide structure in the base 44 guides the second section 442 to slide stably along the first section 441, and the buffer spring 45 absorbs dynamic impact, enhancing the smoothness of operation; secondly, when the first sub-platform 31 is raised to the target height, the lip plate 7 can be flipped outward around its hinge end with the first sub-platform 31, overlapping to the cargo box floor or working ground 1, forming a complete transition path; while the overlapping part 5 connects the platform 1 and the upper end of the first sub-platform 31, and adaptively adjusts the angle with the movement of the platform to eliminate gaps. Furthermore, the ramp-type platform includes multiple preset modes. In truck mode, the sub-platforms within the platform 3 are parallel and non-horizontal to accommodate unloading operations of trucks of different heights. In ramp mode, the sub-platforms within the platform 3 are parallel and the third sub-platform 33 is in contact with the working ground 1, allowing forklifts and other unloading equipment to pass through for corresponding loading and unloading operations. In level mode, the sub-platforms within the platform 3 are horizontally positioned to accommodate unloading operations under special working conditions.
