Description

Technical Field

[0001] This utility model relates to the technical field of logistics transportation and engineering machinery auxiliary equipment, specifically a high-strength ramp platform for containers. Background Technology

[0002] In the operation of container transport of wheeled machinery (such as forklifts, tractors, and mini excavators), ensuring the safe, efficient, and reliable entry and securing of the equipment inside the container has been a long-standing technical challenge. Existing technologies mainly employ the following methods: 1. Direct dragging method: The equipment relies on its own power or external force to forcibly enter the container by overcoming the height difference and gap between the container threshold and the ground. This method has significant drawbacks: First, the equipment tires must withstand the enormous impact of the step, making them prone to slipping and deviating. This not only makes operation difficult and inefficient, but also poses a major safety hazard of equipment tipping over or colliding with the container wall. Second, this method causes severe wear and damage to both the tires and the container threshold structure itself.

[0003] 2. Temporary ramp method: Using simple steel plates or wooden planks as temporary ramps. While this method alleviates the step problem to some extent, temporary ramps lack effective positioning and securing measures, making them prone to lateral slippage during equipment entry. Furthermore, the ramps themselves may move, posing a very high safety risk. In addition, the ramps have limited load-bearing capacity and are unsuitable for heavy equipment.

[0004] 3. Lifting method: Using cranes or other equipment to lift the equipment into the container. This method is costly, has strict requirements for the work site, and the precise positioning and securing of the equipment inside the container remains very difficult and time-consuming.

[0005] In summary, existing technologies generally suffer from three major problems: difficulty in entering the container, unclear positioning, and unreliable fixation, resulting in low operational efficiency, high safety risks, and easy damage to equipment and containers. Therefore, there is an urgent need for a dedicated ramp platform that can integrate guidance, positioning, limiting, and mooring functions, and possesses high strength and reliable connection characteristics. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a high-strength ramp platform for containers to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, a specific embodiment of this utility model provides a high-strength ramp platform for containers, used to connect the ground and the container. It includes a ramp structure, a positioning device, tethering rings, a limiting device, and a connecting mechanism. The ramp structure has its front end touching the ground along its direction of use, and its rear end extending into the container. The upper surface of the ramp structure is provided with an anti-slip structure. The positioning device is disposed on the upper surface of the ramp structure to guide the travel direction of wheeled equipment. Multiple tethering rings are fixedly disposed on the ramp structure. The limiting device is disposed in the rear end region of the ramp structure to restrict the displacement of the wheeled equipment. The ramp structure is detachably and fixedly connected to the bottom plate of the container via the connecting mechanism.

[0008] This utility model discloses a high-strength ramp platform for containers, which has the advantages of convenient entry into the container, accurate positioning, reliable fixation, and strong load-bearing capacity. Its optimized ramp design facilitates the labor-saving and quick entry and exit of equipment. The wheel hub positioning groove can effectively guide the equipment to move in a straight line and avoid deviation. The combination of tethering rings and limiting devices ensures stability during transportation. The high-strength steel frame, reinforcing ribs, and bolted connections significantly improve the overall structural strength, making it suitable for the transportation of heavy equipment.

[0009] In addition, the high-strength ramp platform for containers proposed in the above application may also have the following additional technical features: Specifically, the ramp structure includes a front ramp, a middle ramp, and a rear ramp that are smoothly connected from front to back; the inclination angle of the front ramp is smaller than that of the rear ramp, and the middle ramp is used to achieve the transition between the front and rear ramps.

[0010] Specifically, the inclination angle of the front ramp is 10°-20°, the middle ramp is horizontal, and the inclination angle of the rear ramp is 15°-25°.

[0011] Specifically, the anti-slip structure is an anti-slip texture pressed onto the upper surface of the ramp structure; the frame of the ramp structure is made of high-strength steel, and its lower surface is provided with at least two reinforcing ribs extending along the length direction.

[0012] Specifically, the positioning device is a hub positioning groove recessed on the upper surface of the ramp structure.

[0013] Specifically, the mooring rings are symmetrically distributed on both sides of the ramp structure and in the middle of the upper surface; the mooring rings are metal closed-loop structures, and their bottoms are welded and fixed to the ramp structure.

[0014] Specifically, the limiting device includes a front limiting block fixedly disposed on the upper surface of the rear end of the ramp structure, the front limiting block serving as a thrust point for the weight; the limiting device also includes a rear limiting component disposed at the end of the ramp structure.

[0015] Specifically, the rear limiting assembly includes a limiting baffle and an adjusting bracket for adjusting the height of the limiting baffle, and the rear limiting assembly is detachably connected to the ramp structure.

[0016] Specifically, the connecting mechanism includes a connecting lug plate disposed at the bottom of the ramp structure and a bolt assembly passing through the connecting lug plate; the ramp structure is locked and fixed to the pre-set threaded hole of the container floor by the bolt assembly.

[0017] Specifically, the cross-section of the reinforcing rib is rectangular, its height is 10cm-15cm, and the distance between two adjacent reinforcing ribs is 30cm-50cm.

[0018] The advantages of this invention compared to existing technologies are as follows: (1) The optimized multi-segment ramp design effectively reduces the slope of the equipment entering the cabin, making it easier and faster for the equipment to go up and down the ramp, and significantly improving the work efficiency.

[0019] (2) Guided by the hub positioning groove, the equipment can accurately enter the container's predetermined position along a straight line, avoiding left and right deviations during the entry process and saving adjustment time.

[0020] (3) The combination of the tethering ring and the front and rear limit devices forms multiple insurances, ensuring the absolute stability of the equipment during transportation and greatly reducing the risk of movement and damage.

[0021] (4) The high-strength steel frame, bottom reinforcing rib design and rigid bolt connection with the container floor enable the platform to withstand the load of heavy equipment and expand the scope of application of standard containers for transportation.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figures 1 to 6 As shown in one embodiment of this utility model, a high-strength ramp platform for containers has the core function of being built between the ground and the container 1 to form a stable transition channel, allowing wheeled equipment such as forklifts and tractors to safely and efficiently enter the container 1 and be reliably fixed.

[0028] The ramp platform, as an independent integrated structure, is mainly composed of five functional parts working together: 2. the ramp structure that bears the core load and provides transition functions; 3. the positioning device that guides the direction of travel; 4. the tethering rings for securing the equipment; 5. the limiting device that restricts the displacement of the equipment; and 6. the connecting mechanism that achieves a rigid connection between the platform and container 1. Before being put into use, container 1 must first be placed stably, and then the operator must precisely align the rear end of the ramp platform, i.e., the end closest to container 1, with the entrance threshold of container 1.

[0029] Detailed implementation of ramp structure 2 Ramp structure 2 is the main framework of the entire platform. To achieve a smooth transition and adapt to the internal space of container 1, ramp structure 2 in this embodiment adopts a three-section integrated design, consisting of a front ramp 22, a middle ramp 23, and a rear ramp 24 from front to back. These three ramp sections are connected into a smooth whole by welding or high-strength bolts, with rounded transitions at the joints to ensure a smooth ride for the equipment wheels.

[0030] The front ramp 22 is located on the outermost side, with its bottom directly contacting the ground. To reduce the difficulty and impact of the initial entry of the equipment, the front ramp 22 is designed with a relatively small inclination angle. The intermediate ramp 23 mainly serves as a transition and horizontal support; its length is determined according to actual needs to ensure that the equipment can travel a smooth distance after accelerating on the front ramp 22. The top of the rear ramp 24 connects to the intermediate ramp 23, while its bottom extends directly into the floor of container 1. Because it needs to cross the threshold of container 1, the inclination angle of the rear ramp 24 is slightly larger than that of the front ramp 22, but through optimized design, it is still within the range where the equipment can easily climb.

[0031] The frame of ramp structure 2 is preferably welded from Q355B or higher strength steel to ensure its base strength. On the upper surface of ramp structure 2, anti-slip patterns are integrally pressed using a large press, forming an anti-slip structure 21. These anti-slip patterns can be diamond-shaped, dotted, or other friction-increasing patterns, aiming to significantly increase the friction between the tires and the ramp surface, effectively preventing slippage during uphill or rainy weather operations. To further enhance the overall rigidity and bending strength of ramp structure 2 and prevent deformation under heavy equipment, at least two rectangular reinforcing ribs 25 are welded along the length of the lower surface of the ramp structure 2 frame. These reinforcing ribs 25 act as main beams, working together with the frame to effectively distribute concentrated loads throughout the entire structure.

[0032] Working mechanism of positioning device 3 The core function of the positioning device 3 is to constrain the lateral movement of wheeled equipment during its entry, ensuring that it enters the container 1 along a straight path and avoiding collision with the inner wall of the container. In this embodiment, the positioning device 3 is specifically embodied in a hub positioning groove 31 recessed on the upper surface of the ramp structure 2.

[0033] There are typically two hub positioning grooves 31, arranged parallel to each other on the ramp surface, with their spacing matching the standard wheelbase of the target wheeled equipment. When the equipment drives onto the ramp, its left and right tires naturally embed themselves into the corresponding hub positioning grooves 31. The groove walls physically constrain the sides of the tires, much like the guiding effect of train tracks on wheels, ensuring that the equipment can only move in a straight line along the extension direction of the groove. This design fundamentally eliminates the "deviation" phenomenon caused by minor operational errors or uneven ground during operation, achieving "foolproof" operation that eliminates the need for frequent manual corrections, greatly improving the accuracy and efficiency of cabin entry.

[0034] Cooperative fixing strategy of tethering ring 4 and limiting device 5 Once the equipment has accurately reached the predetermined position, it needs to be secured to prevent movement during transportation. This invention provides multiple layers of protection through the tethering ring 4 and the limiting device 5.

[0035] The tethering ring 4 is a closed-loop metal structure with a sufficient inner diameter, for example, made of bent round steel with a diameter of 20mm. Its bottom is firmly welded to the frame of the ramp structure 2 by full welding. The arrangement of the tethering rings 4 is optimized, symmetrically distributed on both sides of the ramp structure 2 and in the middle area of ​​the upper surface. This distribution provides operators with multiple flexible anchoring points, making it easy to select the most suitable tethering ring 4 according to different binding points on the equipment. Ropes, chains, or special straps are passed through the tethering rings 4 to securely connect the equipment to the ramp platform and the floor of the container 1.

[0036] The limiting device 5 provides physical obstruction and consists of two parts: front and rear. The front limiting block 51, acting as a thrust point for heavy objects, is a rectangular steel plate of considerable thickness, vertically welded to the upper surface of the rear ramp 24, located at its end closest to the interior of the container 1. When the equipment tire contacts the front limiting block 51, it indicates that the equipment has reached its designated position, preventing it from continuing forward and impacting the front inner wall of the container 1 due to inertia or operational errors. The rear limiting assembly 52 is located at the end of the ramp structure 2, and its function is to prevent the equipment from accidentally moving backward inside the container 1. The rear limiting assembly 52 consists of a limiting baffle 521 and an adjusting bracket 522. The adjusting bracket 522 can be positioned at different heights using bolts, thereby raising and lowering the limiting baffle 521 to accommodate equipment tires of different sizes. Once the equipment is in place, adjusting the limiting baffle 521 to a position close to the rear of the tire creates an effective rear obstruction.

[0037] The rigid connection of the connecting mechanism 6 is achieved The stability of the platform itself is the foundation of all its functions. The connecting mechanism 6 is used to achieve a rigid connection between the ramp structure 2 and the bottom plate of the container 1. Multiple connecting lugs 61 are welded to the bottom of the ramp structure 2, particularly below the frame of the rear ramp 24. The connecting lugs 61 have pre-drilled through holes. During installation, high-strength bolt assemblies 62 are passed through the through holes in the connecting lugs 61 and screwed into the pre-drilled threaded holes on the bottom plate of the container 1, or a bolt and nut combination is used to tighten them from below the bottom plate. By symmetrically tightening all bolts, the entire ramp platform is firmly fixed to the container 1, enabling it to withstand the enormous dynamic and static loads generated during the movement of heavy equipment, and forming a stable whole with the container 1.

[0038] Complete Workflow and Principle Overview The complete workflow of this utility model is as follows: 1. Preparation and Installation: Position container 1 stably. The operator moves the ramp platform to the container door, ensuring that the rear ramp 24 accurately aligns with the container 1 entrance and the front ramp 22 smoothly touches the ground. Then, using tools such as wrenches, securely connect the platform to the bottom plate of container 1 using the bolt assembly 62 of the connecting mechanism 6.

[0039] 2. Equipment entry and positioning: The wheeled equipment slowly drives up the front ramp 22, and the tires then fall into the wheel hub positioning groove 31. Guided by the groove wall, the equipment moves in a straight line through the front ramp 22, the middle ramp 23 and the rear ramp 24 in sequence, and smoothly enters the container 1 until the tires contact the front limit block 51 and stop automatically.

[0040] 3. Securing after positioning: After the equipment has come to a stable stop, the operator first adjusts the height of the limiting baffle 521 of the rear limiting component 52 according to the tire position, so that it is tightly attached to the rear side of the tire. Then, select a suitable tethering ring 4 and use rigging such as straps to secure the equipment to the ramp platform and the floor of the container 1 at multiple points.

[0041] 4. Transportation and Dismantling: During transportation, the overall rigidity of the platform, the accurate positioning of the equipment, and the multiple safeguards of mooring and limiting mechanisms jointly ensure the absolute stability of the equipment. Upon arrival at the destination, the mooring is released, the rear limiting component 52 is adjusted, and the equipment can safely drive off the ramp. Finally, the bolt assembly 62 is loosened, and the ramp platform can be removed for easy reuse.

[0042] This invention, through the precise coordination and synergistic operation of the aforementioned components, successfully transforms a complex equipment installation and securing process into a safe, efficient, and reliable standardized operation, effectively solving many pain points in the existing technology.

[0043] It should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made by those skilled in the art without departing from the spirit and principles of this utility model should be included within the scope of protection of this utility model. For example, the positioning device 3 can also adopt the form of an upwardly protruding guide rail; the cross-sectional shape of the reinforcing rib 25 can also be triangular, etc.; these simple variations and substitutions based on the core concept of this utility model all fall within the scope of protection of this utility model. The scope of protection of this utility model shall be determined by the scope defined in the claims.
