[0002] In automated production lines and material handling systems, efficient and stable transfer of workpieces is one of the key factors to ensure production efficiency and product quality.

[0003] Traditional workpiece transfer methods often rely on manual handling or simple mechanical conveyors. These methods suffer from low efficiency, high labor intensity, and poor positioning accuracy when handling heavy, large, or precisely positioned workpieces. Transferring workpieces between different heights is particularly challenging, as a transfer device with flexible height adjustment and stable operation is essential. Utility Model Content

[0023] 1. Guide rail; 2. Mobile base; 3. Lifting platform; 4. Lifting mechanism; 4.1. Support arm 1; 4.2. Support arm 2; 4.3. Push arm; 4.4. Hydraulic cylinder; 4.5. Support shaft; 4.6.

[0024] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0025] It should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood broadly. For example, they can refer to fixed connections, detachable connections, or integrated structures. Those skilled in the art will understand the specific meanings of such terms in this patent based on specific circumstances.

[0026] like Figure 1 and Figure 2 As shown, the hydraulic lifting workpiece transfer device of the present invention comprises a guide rail 1 arranged along the workpiece transfer direction, and a movable base 2 which can move back and forth along the guide rail 1; a lifting platform 3 and a lifting mechanism 4 connected to the lifting platform 3 are mounted on the movable base 2, and the lifting mechanism 4 is used to drive the lifting platform 3 to move up and down; a ball group 5 distributed in a row is arranged on the upper surface of the lifting platform 3.

[0027] Ascent process:

[0028] When the lifting platform 3 needs to be lifted, the hydraulic cylinder 4.4 starts to work, generating an upward thrust.

[0029] The thrust is transmitted to the support arm 1 4.1 and the support arm 2 4.2 through the push arm 4.3, causing them to deform accordingly.

[0030] Due to the hinged and sliding fit relationship between the support arm, the movable base 2 and the lifting platform 3, the deformation of the support arm will drive the lifting platform to rise along the guide rail or the sliding fit surface.

[0031] At the same time, the ball group 5 rolls on the table top of the lifting platform, reducing the friction resistance between the workpiece and the table top and improving the stability of the lifting.

[0032] Descending process:

[0033] When the lifting platform 3 needs to be lowered, the hydraulic cylinder 4.4 changes its working direction, generates a downward pulling force or stops the thrust output.

[0034] Under the action of gravity or the reverse pulling force of the hydraulic cylinder, the push arm 4.3 drives the support arm 1 4.1 and the support arm 2 4.2 to deform in the reverse direction.

[0035] The deformation of the support arm causes the lifting platform to descend along the guide rail (or sliding fitting surface) until it reaches a predetermined position.

[0036] Specifically, the support arm 1 4.1 and the support arm 2 4.2 are arranged in two groups relative to each other.

[0037] Two sets of support arms 1 4.1 and support arms 2 4.2 are provided, forming two sets of parallel quadrilateral structures. This design enhances the stability and load-bearing capacity of the lifting mechanism, making the lifting platform 3 more stable during the lifting process.

[0038] In addition, a support shaft 4.5 is provided between the two opposite support arms 1 4.1 and between the two opposite support arms 2 4.2; a guide pulley 4.6 is installed at the end of the support shaft 4.5; and a limiting rail 4.7 adapted to the corresponding guide pulley 4.6 is provided on the movable base 2 and the lifting platform 3.

[0039] The end of the support shaft 4.5 is provided with a guide pulley 4.6. The guide pulley serves to guide and reduce friction during the lifting process, ensuring that the support arm can move along a predetermined trajectory.

[0040] Both the mobile base 2 and the lifting platform 3 are provided with limit rails 4.7 adapted to the corresponding guide pulleys 4.6. The limit rails provide a clear movement path for the guide pulleys, preventing the support arm from deflecting or shaking during the lifting process, further improving the stability and safety of the lifting.

[0041] As an embodiment, the upper surface of the lifting platform 3 is further provided with a guardrail 6.1 with a loading and unloading opening reserved on one side.

[0042] Specifically, two sets of opposite limiting members 6 are arranged along the loading and unloading ports of the lifting platform 3, and a detachable partition 7 is arranged between the two limiting members 6. A handle 7.1 is installed on the partition 7.

[0043] The main function of the guardrail 6.1 is to prevent the workpiece or the operator from accidentally falling off the edge of the lifting platform during the workpiece transfer process, providing a necessary safety barrier. The removable partition 7 provided between the two limiters further enhances the stability of the workpiece during the transfer process.

[0044] As an embodiment, the mobile base 2 is further provided with a mobile wheel set 8 connected to the guide rail 1. The mobile base 2 and the guide rail 1 are matched through a precise structural design to ensure that the mobile wheel set 8 can fit closely to the guide rail and roll along it.

[0045] The driving mode of the mobile base 2 is usually selected according to specific design requirements and application scenarios. Common driving modes include motor drive, hydraulic drive, pneumatic drive and manual drive.

[0046] It should be noted that, in this article, the terms "include", "comprising" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also includes other elements that are not explicitly listed, or also includes elements inherent to such process, method, article or device. Unless otherwise expressly specified and limited, the terms "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be internal communication between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention.
