Description

Technical Field

[0001] This utility model relates to material handling in the logistics industry, and in particular to an ultra-low profile rotatable lifting platform. Background Technology

[0002] With the continuous development of science and technology, artificial intelligence has been widely applied, leading to the vigorous development of various industries. In the logistics industry, material handling is a crucial link. Moving materials from the ground or low altitude to higher ground is a common operation, but this operation is often time-consuming, labor-intensive, and prone to causing personal injury.

[0003] Currently, this operation typically involves using a hydraulic platform to lift the material to a certain height and then rotate it to complete the material transfer. However, this method has some limitations. First, traditional hydraulic platforms are usually elevated above the ground, meaning that the entire load of material needs to be moved onto the hydraulic platform manually or using lifting equipment (such as forklifts, cranes, or overhead cranes). This not only increases the complexity of the operation but may also introduce additional safety risks.

[0004] To address this issue, some sites opt to excavate trenches in the ground and place the hydraulic platform within them, ensuring the platform's surface is flush with the ground. While this approach does make it easier to load materials onto the hydraulic platform, it also introduces new problems. First, this method requires specific site conditions and necessitates civil engineering work, which is not only time-consuming and labor-intensive but also increases costs. Second, if the site requires further redevelopment later, restoring it to its original state becomes difficult and expensive. Finally, this fixed installation method significantly reduces the equipment's flexibility and mobility.

[0005] Furthermore, existing hydraulic platforms often neglect versatility in their design. Most platforms can only perform simple lifting functions and lack additional functions such as rotation, which limits their application range in complex working environments. At the same time, the structural design of traditional equipment is often relatively complex, increasing maintenance difficulty and cost. Utility Model Content

[0006] To address the aforementioned technical deficiencies, the purpose of this utility model is to provide an ultra-low-profile rotatable lifting platform, which has the advantages of simple structure, convenient operation, strong mobility, no need for site modification, and multi-functional integration. It is particularly suitable for moving materials from the ground and lifting and flipping them.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an ultra-low rotatable lifting platform, comprising a base, a power source installed on one side of the base, and two side panels extending from the other side. The surfaces of the two side panels are respectively provided with an upper hinge hole and a lower hinge hole. One end of the power actuator fixing plate and one end of the lifting power actuator are hinged to the side panel at the lower hinge hole via a hinge pin. One end of the swing plate is hinged to the side panel at the upper hinge hole via a hinge pin. The power actuator fixing plate and the swing plate are hinged together by a linkage rod to form a working cavity. The other end of the lifting power actuator inside the working cavity is connected to the lifting power actuator fixing position located on the swing plate. The power actuator fixing plate is fixedly connected to one end of the rotary power actuator. The other end of the rotary power actuator is hinged to the rotating fixing position of the carrying pallet. The other end of the swing plate is hinged to the lifting fixing position of the carrying pallet. The power actuator fixing plate, the lifting power actuator, the swing plate, and the rotary power actuator are symmetrically arranged on both sides of the carrying pallet. The power source provides power to the rotary power actuator and the lifting power actuator.

[0008] Furthermore, the upper and lower hinge holes on the surface of the enclosure are arranged at an angle.

[0009] The other end of the rotary actuator is hinged to the rotating fixed position of the carrying pallet, and the other end of the swing plate is hinged to the lifting fixed position of the carrying pallet. They are arranged at an angle.

[0010] On the other side of the working cavity formed by the power actuator fixing plate and the swing plate, there is a vertical plate. The vertical plate and the surrounding plate are respectively provided with an upper hinge hole and a lower hinge hole. One end of the power actuator fixing plate and one end of the lifting power actuator are hinged to the vertical plate and the surrounding plate at the lower hinge hole, and one end of the swing plate is hinged to the vertical plate and the surrounding plate at the upper hinge hole.

[0011] When the pallet is not in use, the working surface is 50mm or less above the ground. When the pallet is in use, a pallet is installed inside, and the pallet is lower than the outside height of the pallet. The pallet entrance is provided with a flared opening.

[0012] A cushioning pad is provided below the rotating and fixed position of the carrying pallet, and the cushioning material is polyurethane or rubber.

[0013] The lifting and rotating power actuators are hydraulic cylinders or electric push rods. The power source includes an electrical control box and a hydraulic station for controlling the operation of the hydraulic cylinder or electric push rod. The electrical control box and the hydraulic station are used for lifting and tilting operations via a handle.

[0014] When not in operation, the pallet does not lift or flip, and the entire device is rectangular on the ground. During operation, the lifting actuator extends its telescopic end by manually operating the handle, causing one end of the swing plate to rise continuously. The rotary actuator also extends its telescopic end. During the lifting process, the fixed plate of the actuator rises together with the lifting actuator under the linkage. At this time, the linkage plate gradually tilts as it rises, and the pallet is in an inclined state. When it is raised to an appropriate height or angle, the rotary actuator retracts its telescopic end. At this time, the lifting actuator's telescopic end remains stationary, and the other end of the pallet gradually rises, finally flipping to a flat surface or an appropriate angle for easy loading and unloading of goods.

[0015] The beneficial effects of this utility model are as follows: The device can be raised, lowered, and rotated by manual operation of a handle, enabling materials to be lifted / rotated from the ground to a suitable height / angle. This integrates lifting and rotation functions, reducing the labor intensity of workers and freeing them from heavy workloads by having the equipment perform the task. The design allows the platform to maintain an ultra-low height when not in use, requiring no special site modifications and providing excellent mobility. The application of hydraulic cylinders or electric push rods enables convenient operation and control, offering advantages such as simple structure, easy operation, high mobility, no site modification required, and multi-functional integration.

[0024] See appendix Figure 1-5 This is one embodiment of the present invention, disclosing an ultra-low rotatable lifting platform, including a base, a power source 18 installed on one side of the base, and two side panels 1 extending from the other side. The surfaces of the two side panels are respectively provided with upper hinge holes 3 and lower hinge holes 2. One end of the power actuator fixing plate 4 and one end of the lifting power actuator 7 are hinged to the side panels at the lower hinge hole 2 via hinge pins 6. One end of the swing plate 5 is hinged to the side panels at the upper hinge hole 3 via hinge pins 6. The power actuator fixing plate 4 and the swing plate 5 are hinged together by a linkage rod 9 to form a working cavity. Inside the working cavity... The other end of the lifting power actuator 7 is connected to the lifting power actuator fixing position 10 located on the swing plate 5; the power actuator fixing plate 4 is fixedly connected to one end of the rotary power actuator 8; the other end of the rotary power actuator 8 is hinged to the rotating fixing position 12 of the carrying pallet; the other end of the swing plate 5 is hinged to the lifting fixing position 13 of the carrying pallet; the power actuator fixing plate 4, the lifting power actuator 7, the swing plate 5, and the rotary power actuator 8 are symmetrically arranged on both sides of the carrying pallet 11; the power source 18 provides power to the rotary power actuator 8 and the lifting power actuator 7.

[0025] In this embodiment of the invention, a power source 18 is installed on one side of the base, and two side panels extend out from the other side. Upper hinge holes 3 and lower hinge holes 2 are provided on the surface of the side panels, enabling a hinged connection between the power actuator fixing plate 4, the lifting power actuator 7, and the swing plate 5, forming a working cavity. The lifting power actuator 7 inside the working cavity is connected to a fixed position on the swing plate 5, thereby achieving the lifting function. Simultaneously, the power actuator fixing plate 4 is connected to a rotary power actuator 8, enabling the rotation of the carrying tray 11. The entire structure is symmetrically arranged, ensuring the stability and reliability of the platform.

[0026] Compared to existing technologies, this invention has significant advantages. Firstly, the base height is low, and the working surface of the support pallet 11 is less than or equal to 50mm from the ground when not in use, allowing materials to be easily placed on the platform, reducing the need for manual handling and lifting equipment. Secondly, the lifting and rotating functions of the platform are achieved through the hinged connection between the lifting power actuator 7 and the swing plate 5, making operation more convenient. Finally, the symmetrical arrangement of the entire structure ensures the stability and reliability of the platform, further improving operational safety, while also increasing the efficiency and safety of material handling.

[0027] In this embodiment of the invention, the upper hinge hole 3 and lower hinge hole 2 on the surface of the enclosure are arranged at an angle, not in the horizontal or vertical direction. The main purpose of this angled arrangement is to optimize the structural stability and operational flexibility of the lifting platform. The angled arrangement of the hinge holes allows for more even force distribution on the hinged components during movement, reducing stress concentration and thus extending the service life of the hinged components. Simultaneously, this arrangement also makes the lifting platform more stable during lifting and rotation, reducing the possibility of swaying and tilting, and improving operational safety and reliability.

[0028] Specifically, the obliquely arranged hinge holes can be achieved in the following ways: during the manufacturing of the enclosure, oblique upper hinge holes 3 and lower hinge holes 2 are opened on the surface of the enclosure using precision machining technology to ensure the accuracy of the angle and position of the hinge holes; adjustable hinge pins are used so that the hinge components can be adjusted according to actual needs to achieve the oblique arrangement; and a special hinge assembly is designed so that the hinge components automatically form an oblique arrangement during installation.

[0029] This utility model, through the design of the obliquely arranged upper hinge hole 3 and lower hinge hole 2, significantly improves the structural stability and operational flexibility of the lifting platform, and solves the problems of uneven stress on the hinged parts, short service life, and unstable operation of the lifting platform in the prior art.

[0030] In this embodiment of the invention, the other end of the rotary power actuator 8 is hinged to the rotating fixed position 12 of the carrying pallet, and the other end of the swing plate 5 is hinged to the lifting fixed position 13 of the carrying pallet, arranged obliquely, not in the horizontal or vertical direction. The main purpose of this design is to optimize the motion trajectory and stability of the lifting platform. In the technical implementation process, the oblique arrangement can effectively reduce the lateral force generated during rotation and lifting, and improve the smoothness and accuracy of the system operation. Specifically, the oblique arrangement makes the power transmission path more reasonable, reduces the stress concentration at the hinge point, and thus extends the service life of the system. In addition, this design can also reduce the swaying that may occur during the lifting and rotation of the platform, and improve work efficiency and safety.

[0031] This utility model also proposes that a vertical plate 20 be provided on the other side of the working cavity formed by the power actuator fixing plate 4 and the swing plate 5 on the enclosure plate 1. The vertical plate 20 is provided with an upper hinge hole 3 and a lower hinge hole 2 respectively corresponding to the enclosure plate 1. One end of the power actuator fixing plate 4 and one end of the lifting power actuator 7 are hinged to the vertical plate 20 and the enclosure plate 1 at the lower hinge hole 2. One end of the swing plate 5 is hinged to the vertical plate 20 and the enclosure plate 1 at the upper hinge hole 2. Through the above technical solution, one end of the power actuator fixing plate 4, one end of the lifting power actuator 7 and one end of the swing plate 5 are hinged between the enclosure plate and the vertical plate, making the entire lifting platform more stable and reliable during the rising and turning process.

[0032] This embodiment of the invention also proposes that the working surface of the carrying pallet 11 is less than or equal to 50mm above the ground when not in use, and that a pallet 16 is installed inside the pallet 11 when in use. The pallet 16 is lower than the external height of the carrying pallet 11, and a flared opening 14 is provided at the entrance of the carrying pallet 11. The pallet 16 can be easily fed onto the carrying pallet 11 by a hydraulic trolley or other handling tools (the carrying pallet 11 has a ground-level design, which basically allows for bump-free operation).

[0033] This invention reduces the height of the support pallet 11, making it easier to place materials onto the platform. Specifically, the working surface height of the support pallet 11 when not in use is less than or equal to 50mm, allowing materials to be easily placed without additional lifting equipment. Furthermore, when in operation, the support pallet 11 is equipped with an internal pallet 16, the height of which is lower than the external height of the support pallet 11, further reducing the difficulty of material placement. A flared opening 14 is provided at the pallet's entrance for convenient material loading.

[0034] This utility model also proposes to provide a buffer pad 17 below the rotating fixed position of the carrying tray 11. The buffer material is polyurethane or rubber. By providing the buffer pad 17 below the rotating fixed position of the carrying tray 11, the protection of the equipment and the extension of its service life are achieved. The material of the buffer pad 17 is polyurethane or rubber, which have good cushioning performance and durability, and can effectively absorb vibration and impact, reducing wear and damage to the equipment during rotation. In addition, the buffer pad 17 can be designed to be detachable for easy maintenance and replacement. The thickness and hardness of the buffer material can be adjusted according to specific application requirements to provide the best cushioning effect. By adding the buffer pad 17, the practicality and reliability of the ultra-low profile rotating lifting platform are further improved. This solution can better protect the equipment, extend its service life, and reduce maintenance costs.

[0035] This invention also proposes that the lifting actuator 7 and the rotating actuator 8 are hydraulic cylinders or electric push rods. The power source 18 includes an electrical control box and a hydraulic station for controlling the operation of the hydraulic cylinders or electric push rods. The electrical control box and the hydraulic station are connected to a handle 19 for lifting and tilting operations. Hydraulic cylinders and electric push rods are common actuator types. The former drives the piston movement through the pressure of hydraulic oil, while the latter drives the screw or gear mechanism through an electric motor to achieve push-pull movements. Both have high reliability and long service life, making them suitable for various industrial automation equipment. Controlling the working state of the hydraulic cylinders or electric push rods through the electrical control box and the hydraulic station enables precise lifting and rotating actions. The electrical control box has built-in control circuits and programs, which can automatically adjust the working state of the hydraulic cylinders or electric push rods according to preset parameters and operational requirements. The hydraulic station provides the pressure source of hydraulic oil, ensuring that the hydraulic cylinders can complete their actions smoothly. Through the handle 19, operators can easily control the lifting and tilting, improving the ease of operation and safety of the equipment.

[0036] The above description is merely an embodiment of this application and is not intended to limit the scope of protection of this application. Various modifications and variations can be made to this application by those skilled in the art. Any 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.
