Description

Technical Field

[0001] This utility model belongs to the field of logistics loading and unloading technology, specifically a rotating docking platform for intelligent logistics cargo loading and unloading. Background Technology

[0002] The intelligent logistics cargo loading and unloading rotary docking platform is mainly used for loading and unloading goods. The platform connects the truck bed and the storage platform to realize rapid loading and unloading of goods.

[0003] A search revealed that CN217577517U discloses a logistics cargo loading and unloading platform, including a reinforced base plate. A lifting device is installed on the upper center of the reinforced base plate, and assisting lifting components are installed on the upper side of the reinforced base plate and on both the left and right sides of the lifting device.

[0004] Currently, when a truck's parking position deviates, the equipment cannot adjust itself. The truck must be manually guided to move repeatedly to calibrate its position. This not only significantly extends the docking preparation time but also increases the risk of collisions between the vehicle and the platform or equipment due to improper vehicle movement, leading to cargo damage or equipment failure. Furthermore, the docking process relies on precise vehicle parking, which places high demands on the driver's skills. In actual operations, parking deviations are difficult to avoid due to factors such as site conditions and traffic flow. This directly results in low efficiency in the pre-loading and unloading preparation stage, severely restricts the overall loading and unloading operation rhythm, and fails to meet the needs of intelligent logistics for efficient and convenient docking.

[0005] Therefore, a rotating docking platform for intelligent logistics cargo loading and unloading is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the shortcomings of the existing technology and solve at least one of the technical problems mentioned in the background technology, this utility model proposes a rotating docking platform for intelligent logistics cargo loading and unloading.

[0007] The technical solution adopted by this utility model to solve its technical problem is: the intelligent logistics cargo loading and unloading rotary docking platform of this utility model includes a base, a plurality of lifting mechanisms are evenly arranged on the base, a first bearing platform is arranged on the lifting mechanism, and a second bearing platform is arranged above the first bearing platform.

[0008] A lifting and rotating mechanism is provided in the middle of the base. The lifting and rotating mechanism includes a power component. A lifting and rotating rod is provided in the middle of the power component and on the power component. The lifting and rotating rod passes through the first support platform. A double-structure force guide plate is provided on the lifting and rotating rod. The end of the double-structure force guide plate away from the lifting and rotating rod is fixedly connected to the second support platform.

[0009] Preferably, the lifting mechanism includes a fixed block whose bottom is fixedly connected to the base, an outer cylinder is provided in the middle of the fixed block, and a lifting push rod is provided inside the outer cylinder.

[0010] Preferably, a force-bearing plate is provided on the top surface of the lifting push rod, the force-bearing plate is fixedly connected to the first bearing platform, and fasteners are provided on the outer periphery of the outer cylinder and on the upper surface of the fixing block.

[0011] Preferably, the lifting push rod is provided with a second lifting rod, which passes through the force plate and the first support platform, and the top surface of the second lifting rod is fixedly connected to the second support platform.

[0012] Preferably, the second support platform is provided with connectors at both ends, and the other end of the connector is provided with an overlapping lip plate.

[0013] Preferably, both the first support platform and the second support platform are regular polygons.

[0014] Preferably, the two sides of the fixing block are support plates, one end of the support plates on both sides of the fixing block is fixed to the base, and the other end is parallel to the bottom surface.

[0015] The beneficial effects of this utility model are as follows: Relying on the lifting and rotating mechanism in the middle of the base, the second carrier platform can be driven to rotate flexibly to the angle corresponding to the carriage, eliminating the need for manual guidance of the truck to repeatedly move and calibrate, directly eliminating the time loss caused by moving the truck, greatly shortening the docking preparation time, significantly improving the overall efficiency of loading and unloading operations, and reducing the risk of collision between the vehicle and the platform and equipment during the moving process; With the lifting mechanism evenly distributed on the base, and the auxiliary support of the second lifting rod for the second carrier platform, the platform can adjust its height synchronously to adapt to the height differences of different types of carriages. The flexible transition of the connecting parts at both ends of the second carrier platform and the overlapping lip plate can tightly connect the carriage and the platform, preventing the goods from falling during transfer, further ensuring operational stability, and fully meeting the efficient and precise loading and unloading needs of intelligent logistics.

[0025] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Specific implementation examples are given below.

[0027] Please see Figures 1-5This utility model provides an intelligent logistics cargo loading and unloading rotating docking platform, including a base 1; multiple sets of lifting mechanisms 2 are evenly arranged on the base 1, a first bearing platform 4 is arranged on the lifting mechanism 2, and a second bearing platform 5 is arranged above the first bearing platform 4; a lifting and rotating mechanism is arranged in the middle of the base 1, the lifting and rotating mechanism includes a power component 30, a lifting and rotating rod 31 is arranged in the middle of the power component 30 and located on the power component 30, the lifting and rotating rod 31 passes through the first bearing platform 4, a double-structure force guide plate 32 is arranged on the lifting and rotating rod 31, and the end of the double-structure force guide plate 32 away from the lifting and rotating rod 31 is fixedly connected to the second bearing platform 5; the base 1 is a basic support component, welded from high-strength alloy steel, with excellent load-bearing strength and structural stability, and can adapt to the heavy load requirements in logistics loading and unloading scenarios. Multiple sets of lifting mechanisms 2, preferably four sets, are evenly distributed on the base 1 and symmetrically arranged in the four corner areas of the base 1. The top of the lifting mechanism 2 supports the first support platform 4. A second support platform 5 is arranged parallel above the first support platform 4 for directly receiving and transferring goods. The middle of the base 1 integrates a lifting and rotating mechanism to provide the second support platform 5 with the power for angle adjustment and synchronous lifting. At the same time, the two ends of the second support platform 5 are also equipped with connecting parts 6 and overlapping lip plates 7 to achieve flexible and stable docking with the truck body.

[0028] Furthermore, such as Figure 4 and Figure 5 As shown, the lifting mechanism 2 is the core component for achieving platform height adaptation, and its structure is as follows: Fixed block 21: As the basic fixing component of the lifting mechanism 2, its bottom is rigidly connected to the base 1 by high-strength bolts. The fixed block 21 adopts an integrated casting structure of "double-sided support plates + central connecting block". One end of the two side support plates is fixed to the base 1, and the other end extends horizontally parallel to the ground. This triangular reinforced structure greatly improves the support stability of the fixed block 21, effectively distributing the load during the lifting process and preventing local pressure deformation of the base 1.

[0029] Outer cylinder 22: Located in the middle of the fixed block 21, it is an integral casting with the fixed block 21. The inner wall is precision machined to ensure straightness and provides guidance for the lifting and lowering movement of the internal lifting push rod 24.

[0030] Lifting push rod 24: An electro-hydraulic push rod can be used, or a servo-electric push rod or a pneumatic push rod can be selected flexibly according to the needs of the scenario. Linear lifting is achieved by driving a hydraulic cylinder or a lead screw and nut pair through an internal motor. A force-bearing plate 25 is fixedly connected to the top surface of the lifting push rod 24. The force-bearing plate 25 is a thick-walled metal plate, which is fixed to the first support platform 4 by welding or bolting, thereby transmitting the lifting force of the lifting push rod 24 to the first support platform 4.

[0031] Fastener 23: It is a ring-shaped locking sleeve structure, which is sleeved on the outer periphery of the outer cylinder 22 and attached to the upper surface of the fixing block 21. The fastener 23 is arranged to fix the outer cylinder 22 and prevent shaking.

[0032] Furthermore, such as Figure 3 The lifting and rotating mechanism shown is used to drive the second support platform 5 to achieve angular rotation and synchronous lifting. Its structure is as follows:

[0033] Power Component 30: This is an integrated power unit combining "lifting drive + rotation drive," and can adopt a combined structure of "servo motor + hydraulic lifting cylinder + rotary joint." The servo motor provides high-precision power for the rotational motion, the hydraulic lifting cylinder provides high-load output for the lifting motion, and the rotary joint realizes the composite transmission of power.

[0034] The lifting and rotating rod 31 is vertically positioned in the middle of the power component 30 and rigidly connected to the output end of the power component 30. It can both lift and rotate vertically under the drive of the power component 30. The lifting and rotating rod 31 passes through the first support platform 4, which has a corresponding through hole. A high-precision bearing, such as a tapered roller bearing, is embedded in the hole, allowing the lifting and rotating rod 31 to smoothly complete lifting and rotating movements relative to the first support platform 4, while simultaneously bearing radial and axial loads.

[0035] Dual-structure force guide plate 32: This is a metal sheet with high rigidity and fatigue resistance, such as an alloy spring steel sheet, which is fixed to the outer circumference of the lifting and rotating rod 31 in a radial pattern. The end of the dual-structure force guide plate 32 away from the lifting and rotating rod 31 is fixedly connected to the bottom surface of the second support platform 5 by bolts, thereby realizing the synchronous transmission of "lifting force + rotational force" to the second support platform 5—when the lifting and rotating rod 31 rises and falls, it drives the second support platform 5 to rise and fall synchronously; when the lifting and rotating rod 31 rotates, it drives the second support platform 5 to rotate synchronously to the target angle.

[0036] Furthermore, such as Figure 1 and Figure 2 To further improve the stability and uniform force distribution during the lifting and lowering of the second support platform 5, a second lifting rod 8 is fixedly connected to the lifting push rod 24. The second lifting rod 8 is a cylindrical metal rod, and its bottom is rigidly connected to the top of the lifting push rod 24 via a connecting seat, allowing it to rise and fall synchronously with the lifting push rod 24. The second lifting rod 8 passes through the corresponding through holes in the force-bearing plate 25 and the first support platform 4, with wear-resistant bushings installed in the inner walls of the through holes. Its top surface is fixed to the bottom surface of the second support platform 5 by bolts. When the lifting push rod 24 drives the first support platform 4 to rise and fall, the second lifting rod 8 synchronously drives the second support platform 5 to rise and fall, playing the role of "auxiliary support + synchronous guidance," preventing the second support platform 5 from tilting or jamming due to unilateral force, and ensuring the stability of the height adjustment process.

[0037] Furthermore, such as Figure 1As shown, to achieve flexible and seamless docking between the platform and the truck bed, connectors 6 are provided at both ends of the second bearing platform 5. The connectors 6 are elastic connectors with buffering properties, such as rubber buffer blocks or metal connectors with built-in springs, which can absorb impact energy when the platform docks with the truck bed, avoiding damage to goods or equipment caused by rigid collisions.

[0038] Overlapping lip plate 7: The surface of the inclined plate structure is treated with anti-slip treatment, such as anti-slip texture. One end is connected to the second support platform 5 through the connector 6, and the other end extends in a "slope" shape to facilitate smooth overlap with the bottom plate of the truck bed, forming a transition surface for cargo transfer, completely eliminating the gap between the truck bed and the platform, and preventing cargo from falling during the transfer process.

[0039] Both the first support platform 4 and the second support platform 5 are designed as regular polygons, preferably regular quadrilaterals. This shape has advantages in angle adaptability and load-bearing stability. The advantage in angle adaptability is that the number of sides of the regular polygon is uniform, which makes it easy for the lifting and rotating mechanism to drive the second support platform 5 to rotate to any angle, so that it can smoothly dock with the side of the truck body and adapt to trucks with different parking angles.

[0040] Its load-bearing stability advantage lies in its regular square platform area, which provides a stable placement surface for goods, especially those with regular packaging, such as palletized or boxed goods, thereby improving the stability of goods during transportation.

[0041] The working process of this utility model is as follows: If the angle deviation of the truck's parking position is inconsistent with the platform's preset docking angle, the power component 30 of the lifting and rotating mechanism is activated using a remote control. The power component 30 drives the lifting and rotating rod 31 to rotate, and through the force transmission of the double-structure force guide plate 32, it drives the second support platform 5 to rotate synchronously until the side angle of the second support platform 5 is completely matched with the side angle of the truck's cargo box. This process eliminates the need for manual guidance of the truck to repeatedly move and calibrate, which significantly shortens the docking preparation time by more than 60% compared to traditional manual vehicle movement, and completely eliminates the risk of collision between the vehicle and the platform or equipment during the vehicle movement process.

[0042] When there is a height difference between the truck bed and the platform, the lifting push rods 24 of the multiple lifting mechanisms 2 are activated: the lifting push rods 24 extend and retract, driving the first support platform 4 to rise and fall through the force plate 25; at the same time, the second lifting rod 8 moves synchronously with the lifting push rods 24, driving the second support platform 5 to rise and fall synchronously, so that the top surface of the second support platform 5 is completely consistent with the height of the truck bed.

[0043] After angle and height calibration, the overlapping lip plates 7 at both ends of the second bearing platform 5, through the buffering effect of the connecting parts 6, smoothly overlap onto the floor of the truck bed, forming a smooth transition surface of "platform - overlapping lip plate 7 - truck bed". At this time, goods can be efficiently transferred between the second bearing platform 5 and the truck bed using loading and unloading equipment such as forklifts and conveyors, completely avoiding goods falling due to gaps or collisions, ensuring operational stability and cargo integrity; all contents not described in detail in the instruction manual are existing technologies known to those skilled in the art, and the model parameters of each electrical component are not specifically limited, and conventional equipment can be used.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
